Take a car seriously to detect new technology

Produce practice examine promoted detect the value engine of new technology is made in " 2 micron project " the enlightenment that uses practice uses optics to interfere 3D to become to be being measured like the principle the surface undertakes nicety detects, say again " holography is measured " , it is a new technology, but there already was success application in foreign auto industry. Roll out this one technology and relevant product (beautiful) company of division benefit power ever made count in last few years second explain to public, still provided a prototype for some college, but the impact is not big. Rise at the beginning of 2010 oneself, be located in Guangxi Liuzhou on steam is general university of traffic of 5 water chestnut, Shanghai and (beautiful) company combination comprised division Hui Li to produce learn to grind working group, establish " engine makes two micron " project, in order to explore dimension of the key in manufacturing process, form the tolerancepublic errand influence to the product, reach component to create the concern that precision and function match, and afore-mentioned optical interference 3D become the high accuracy plane that resemble to measure a technology (also weigh ShaPix) become adoption main method. Graph the main job principle of the fundamental ShaPix that 1 ShaPix measures sees a picture 1, it is after using laser to reflex, experience wave carry have news of height of the surface that be measured, will interfere image changeover to generate 3D height graph to represent the exterior state of the spare parts that be measured. The measurement that with CMM this is familiar with method photograph is compared, in resolution identical (all be 0.

1mm) below the circumstance, it is can more accurate, intuitionistic, fast the result that ground expression detects in real time. Graph the 2 measurement that are pair of cylinder body surfaces, show its end panel of a few cylinder bushing exists slightly protuberant circumstance. On steam is general the applied example that the delegate of 5 water chestnut passes a few vivid, successes was mirrorred begin " 2 micron project " the practical effect that obtains since the project, ask like higher to having technology (flatness ﹤ 0.

05, Ra0.

8) because crock lid underside receives the reason such as the knife to cause workpiece appearance the problem such as out of tolerance of surface roughness of section of raised, section. But of classics ShaPix intuitionistic detect, search quickly gave relevant influencing factor, specific aim ground did craft to improve, produced clear result (graph 3a is before improving, graph 3b is after improving) . Graph the planar measurement on 2 cylinder body result sketch map 3 consult detect result, the treatment effect signal after improving technology " altitude deeply cold " no longer, industrial CT is used morely already at producing industrial CT actually is at present the most advanced nondestructive detects one kind technology, but the use range in home is very at present narrow. Nevertheless this kind of circumstance is in already had apparent change in last few years, on this second annual meeting, have early or late (beautiful) Polaris is become mix like the company (heart) according to division inspected bright ray company to introduce this product technology, showed to everybody especially the success was obtained to use fact of this be related in more and more enterprises. Graph the main job principle of 4 industry CT pursues series of CT of 5 complete functions (left) and compact model CT series (right) the basic structure of CT of industry of give typical examples includes collimation of ray source, around implement, system of device of detector, mechanical scanning, electronics and interface, computer and, see the graph is shown 4 times. It can is opposite the form that scatheless premise leaves the content that be measured to resemble with image of 2 dimension fault or three-dimensional block diagram, the qualitative, state that be short of caustic and interior dimensions have the composition with fast, clear, accurate, intuitionistic internal to workpiece ground, composition, capable person test. What ask to product quality as the user is ceaseless rise, domestic and international business circles detects to X ray the demand that reachs computer fault scanning increases increasingly, and to reduce " altitude deeply cold " actual condition, each manufacturer developed sexual price to compare taller, the economy with stronger specific aim (say again " compact model " ) industrial CT Compact. Compare the series of complete function CT with high price, compact model CT uses room of compositive type lead to devise an idea, cover an area of an area small, the basis is measured the actual condition of workpiece, x ray source chooses small central issue, 450kv and line array detector, provided the optimal measure that can obtain data of accurate, full-scale test quickly already for medium and small businesses thereby, obtain the economic result that price of high-powered, tall sex compares again. In fact, the complete function CT that is like one steam masses, Shanghai masses to wait for large company place to deploy than minority (see a picture 5 left) , CT.

Compact (see a picture 5 right) expenditure is his only 40% the left and right sides, it suits to detect particularly medium or small all sorts of cast of dimension. Industry of hub, tire is the main component of auto industry, immanent to its product quality has the company strict control all takes very seriously, but stem from economically consideration, at present home uses industrial CT to regard as detect the enterprise of the method is very few still. On current annual meeting, "The Hua Shun that wear card " introduced a kind relatively of economy adopt X ray to become in real time picture full automatic the new method of blemish identifying: Multistage amends median to filter, through X light chain detects undertake blemish precaution is mixed cast a process to amend. Graph 6 it is X ray chain detects principle graph, the picture that shows by screen in the graph has been become by treatment but by ADR (automatic blemish identifies) processing can inspect body with what evaluate. Chain of ray of Nextpage graph 6 X detects the applied level that principle graph optics measures and enclothe a face to promote a graph 8 white light ceaselessly detect the sketch map that replaces traditional coordinate to measure way is current on annual meeting, many users pass the production of oneself to carry out, reflection goes out in this on one hand rise ceaselessly and expand what use level and range, and the value that in stimulative production, improvement quality respect shows. Attend first detect of annual meeting " Liuzhou force of motor-driven of willow of 5 water chestnut " the quality that introduced how to apply laser scanning to be checked in order to rise in workpiece quality inspection on the meeting. They measure the PH10 of machine to measure in 3 coordinate on joined laser measures a head, eliminated blind angle of the existence when original contact method is being measured, multichip measure data to go all out close complex, go all out combine the drawback with low precision. And be collected through nodding cloud data and handle, use automatic best-fitting to be opposite wait for 4 kinds of methods together, and the method such as chromatogram of the reference that uses a graph to change, deviation, see the workpiece that be measured and digital-to-analogue dimension, body OKer and intuitionisticly the difference of existence. The principle sketch map that graph 7a and B are orgnaization scanning respectively and the installation that measure a head to go up in CMM pursue. On steam is general 5 water chestnut criterion besides did on congress in be being made about engine " 2 micron project " outside the report, introduced to be in to the delegate that comes from countrywide each district again truckload Hexagon of the application in production (Haikesikang) the case that Bai Guang surveys a system. They point out, traditional coordinate is measured although machine is mature, also have many advantages, but put in a few apparent inadequacy, appropriative will be depended on to secure when detecting like workpiece measure stand, the condition of individual spare parts is not represented assemble position, when producing a problem how from go up to search a reason to wait a moment downward. And what measure a technology solely in vain is perfect intervene, made up for afore-mentioned inadequacy greatly, graph 8 be a figure replace a plan. Because Bai Guang measures measure to have high accuracy, cover a range big, can produce more detecting data, portable, get used to more workshop environment, powerful trends, fast, dimension to analyse ability, because this is in,answer a few intractable quality analysises, test to asked to its advantage shows when the problem. They were listed how to search a car to close the case of the source with too great power, leave very deep impression to everybody. Graph 7 laser scanning measures working principle graph and installation to measure the laser probe machinist on machine at coordinate the laser that academy of the 9th design introduced course of study to already obtained increasing applying gradually in domestic automobile manufacturing industry is online detect technology, point out, already came true as this technology homebred change, craft investment is reduced, and the quality monitoring of process of production of its dialogue automobile body comparatives again apparent, because this has wide development perspective. The exemple in the report that providing for congress lifted what build early or late in nearly 10 years " car of Hua Chen China " , " one steam nimble amounts to a car " , " one steam liberates a lorry " wait to have representative product line a few times, they all are stationary laser vision (CCD) software of processing of sensor union image and automobile body of dialogue of computer control system undertake of 100% detect. Graph the 9 applied example that are the automobile body product line that nimble of one steam masses amounts to a car, laser is online detect device installs advanced wind window to be versed in, detect time is 16s. Graph 9 medium A not stationary laser is online survey equipment solid scene, b is to detect place sketch map. Graph the laser on product line of 9 white automobile body is online detect window of the wind before device is reached measures place sketch map to pursue the actual application of 10 portable optical CMM in addition, (Canada) form achieved Creaform to roll out Handy PROBE of measuring instrument of optics of the 3rd acting hand-held on the meeting, this kind is called " portable optical CMM " the instrument detects not only precision is tall, uncertainty of measurement is in less than of 22 μ M, and efficiency is taller, use device of the type that do not have an arm and wireless data to transmit, have be opposite automatically neat function. It passes the name says the double CCD tracker of C-Track will come true powerful three-dimensional measure, achieved whole system to undertake automatic coordinate is opposite constantly neat working way. Graph the 10 working example that are Handy PROBE, see from inside the graph, the lower end that holds an instrument in handlers has with be measured to be in conterminous touched probe, and left rear it is C-Track namely. Because hold an instrument to weigh 450g only, make an operation very deft. Home detects the car ABS that the technology obtains progress to innovate prevents those who hold dead testing stand in the arms to be born to be developed by limited company of science and technology of equipment of car of Yantai smooth house " car ABS is prevented hold in the arms dead reach through model full automatic four-wheel fixed position is integrated testing stand " be can use one kind at car plant directly truckload of product line efficient. Graph 11 cars ABS is prevented hold in the arms dead reach through model full automatic four-wheel locate this equipment is in integrated testing stand 2 respects innovate somewhat, it is high speed trends detects ABS apply the brake, slippery watch of travel space, speed examines, say to weigh (annulus, axis) etc. 2 was to use through model get used to wheelbase oneself full automatic four-wheel the new technology that fixed position detects. Detect in will traditional car low speed (2.

The speed of 5km/h) or the static state detects, take the place of then detect with be close to the high speed at transport condition of car high speed more (the speed of 30km/h or 50km/h above) later, came true to detect the accord of condition and transport condition of car high speed, thereby the function of apply the brake when travel of high speed of car of can real report. Because this detects advancedly,means approachs the actual travel state of the car, can better land gets used to reason the need that new and high technology uses the car. For instance the characteristic that 4 drive car detects reachs contented full-time deploy ASR or ESP to prevent what drive wheel skids intelligence controls systematic traffic to examine demand, if use the sort of existing turning over,changed thereby stage of force apply the brake and speed stage are met the current situation that cannot detect. "Ceaseless enterprising, force starts banner brand, make contribution for all trades and professions " graph a kind of 12 model is measured spare parts give typical examples enterprise of civilian battalion high-tech " the day allows science and technology " also showed on current annual meeting in recent years a few new products. Among them, the contact of the blame that return number with most deep impression giving a person is video detect technology, they go up in original basis, extended sheet again second or batch check line is apart from, duplicate measure repeatability geometry quantity, coordinate to place, the graph compares a lot of function such as panoramic to mixing scanning. Because the enterprise insists to set out from the real need of the user, make for its even detect plan -- call " custom-built change measure " , while because this is in in recent years,the technology obtains progress ceaselessly, the client also is expanding every year. Graph 12 it is a typical case, of blueprint be measured make for aluminium of accurate mould pressing. The requirement carries circular arc radius to undertake detecting each to its, precision is 10 μ M. The requirement of the user includes to be opposite mould, first are measured with the process that regards main body as working content, and the set of task of the measurement that functional respect needs to have pair of basic measure, batch, and wait to measuring a result to undertake SPC analyses processing multinomial. To the project of the relatively severe exacting that a such medium and small businesses put forward, day accurate science and technology gives well finish. The fill of quantity appearance new product that tall sex price compares the blank of user demand estimates the more influential business in bearing industry twice in home: The Furuide that do not have stannum and stride day of machine without stannum, introduced on the meeting nearly one, roll out 2 years can replace foreign product, fill tall sex price compares blank of domestic user demand detect equipment and quantity appearance. Nextpage pursues 13 connecting rod are measured automatically say to weigh grading the machine that make bid is measured automatically by the connecting rod that develops without Xifuruide say to weigh grading the one level that the machine that make bid uses at limited company of Shanghai general motors is supplied -- a when Shanghai joins athletic force, this product line can process the connecting rod of 4 kinds of norms at the same time. Measure machine (see a picture 13) use full automatic job means, flow is: After treatment cleans ending connecting rod to be entered through carrying a line automatically, ordinal through retroflexioning, sentence beforehand, say heavy, dimension detects, work mark and grading etc, of all measure that implement connecting rod finally, weight detect reach grading make bid. Graph the Zun Tu of 13 is detect part, right graph is grading orgnaization. Long-term since, the integrated control machine with this kind of whole more complex system basically is by abroad forestall of place of a few companies, the price is high, the engine plant that causes domestic share to have demand or professional connecting rod produce a business, because this can choose to be measured by hand only consequently formerly,meet, say to be reached again make mark device in group. This equipment of own development tries hard via what come 2 years and improve ceaselessly already reached higher level, mix through reasonable mechanical design adjust plan, can realize the measurement of connecting rod of 4 kinds of different specifications, its are big aperture is the biggest differ can amount to 4mm, small head aperture differs 1mm, and the center is apart from differ for 8mm. Assuming 100% examining circumstances to fall, this measures the metre of machine to be able to amount to 12s, the interval of the two workpiece when this metre and serial production move is identical. In addition, this machine still has SPC statistic to analyse a function, can undertake to workpiece of avery kind of statistic is analysed alone. According to the need of the user, measure machine is OK deserve to environmental temperature compensates device, can be in right now 5 ° - work normally below the environment between 40 ° . Graph the 14 efficient whorl that take deepness reading stop flux compasses pursues 14 be by " without machine of Xi Mai day " whorl of deepness of type of two kinds of of development efficient reading stops flux compasses, its biggest characteristic is can numerate conveniently the actual measurement value of hole depth, and can use same gauge detects the screw of different deepness, if whorl is identical. Undoubted, this series product also can be extended conveniently, measure in order to be used at general smooth aperture, the commonnest cooperate whorl aperture namely measure, detect the whorl bottom outlet of workpiece. In addition, this one product has knockdown characteristic, gauge noumenon and whorl measure a head to show fission structure, measure a head through changing can very realize gauge to change conveniently model or update. In the graph a right kind those who adopt is differential canister scale reading, and Zun Fang the sort of used number to show pattern. Undeniable, it is the product that Danish Leitech company rolled out this kind to win patent above all before New Year more, obtained the welcome of the big batch manufacturer that is a delegate with automobile industry. Later, although the photograph is similar,again a few Euramerican manufacturers that measure appearance were developed by proper motion of this one concept, but the product that the texture differs completely, the car manufacturer that does not cross pair of home, price on the high side is a problem from beginning to end. Without Xi Mai day proper motion developed this product to absorb each strong point, have very high gender price to compare. The spot, real time, online / continue to become in monitoring of machine, process detect technical heat " the spot, real time, online / in monitoring of machine, process " these element also got sufficient test and verify on current annual meeting. Of the measuring instrument of portable surface roughness that new generation uses at producing the spot roll out a graph 15 new generation are applicable the measuring instrument of portable surface roughness that produces the spot (day) Tokyo nicety is a famous testing instrument manufacturer, and its product covers a range very wide, besides measure actively, the check outside the line is provided outside waiting for series product, outline of figure of 3 coordinate, face is measured machine be in Japan also is main supplier, and former amount to in Japanese market share 50.

3% , latter is achieved 60.

4% . Go up in current annual meeting however, tokyo nicety is emphasized those who roll out is although,one looks small, appearance of portable surface surface roughness measures the new generation that favors however by the enterprise machine SURFCOM FLEX. Well-known, long-term since surface roughness measuring instrument is to serve as accurate instrument to put measure in essence of life indoor, but the change as quality awareness, the manufacturer developed many equipment to agree with this kind of instrument of cell, but, true appropriate the measuring instrument of portable surface roughness at producing the spot is not simple, must have adaptability strong -- answer poorer, the different ground of each different nods the environment, operate easily -- quick, simple, master easily, the function is rich and have the changeability that chooses different drive ministry. Graph 15 be this kind of small-sized instrument show a picture, a is compact model the drive ministry of surface roughness appearance, the biggest measure span to amount to 50mm, and B is ministry of drive of 3 kinds of portable instruments a medium kind " standard type " , additional 2 kinds " keep out of the way " and " transverse measure model " . See from graph C, the controller that matchs is compact, concise, it is very easy to use pushbutton to operate, and among them screen is very big, the USB interface of earning can be occupied into linage general, also can use of course " U " dish save data. In machine measure / the range of products that the series of monitoring states well-known Italian MARPOSS company is abounded extremely likewise, also introduced its to be full of characteristic on the meeting " in machine measure / monitoring " the product of series, from the graph 16a can see, besides right lower part showing a picture is design treatment medium or outside the moving condition monitoring of numerical control machine tool, the others all is to belong to pair of workpiece inside, outside dimension / the position undertakes detecting, and be opposite inside implementation machine knife. These device have very bright characteristic, if use wireless signal to transmit a system, detect of the result send concise; In measuring a head, have infra-red measure a head, super- small-sized and infra-red measure head and radio to survey first class; System of the double optics that measure a head can use have the aid of a receiver, interface and measure a head with two kinds when measure at be being mixed to the knife suitable. And the face of supervisory system of MMS machine tool that graph 16b place shows, provided temperature, displacement, force transducer or separator bed status -- after vibration or power detect, had function is extremely rich, rose to run the stability of medium machine tool, dependability and security greatly. Graph 16 MARPOSS is in machine detect technical coordinate is measured machine walk into manufacturing site to pursue into the trend gradually 17 coordinate are measured machine already measured Zeiss of room trend workshop from essence of life (Cai Si) the coordinate of the company measures machine product celebrated domestic and international, but the side key when they change past introduction however on current annual meeting -- precision and stability, the key undertook recommending to applying to the type of workshop spot and relevant case. Graph 17a is a kind of machine DuraMax that develops technically for this one purpose, it already won success application in many enterprises, its are main the characteristic is as follows: (1) the structure is compact, take up the space is little; (2) can get used to the working environment with bigger change of the temperature below manufacturing site condition; (3) see from the graph, lade the workpiece that be measured can from on, left, medium, right 4 direction are entered measure machine, very convenient; (4) no matter be the angle from handlers,still be from cooperate with what produce working procedure, suit very; (5) have quite tall measurement precision, wait for the machine of norms to one Taichun, its MPEEmax=2.

4 μ M+L/300. Graph 17b is case of an actual application, be located in " Shanghai general motors " cylinder body product line is, just use another kind of means, right now coordinate is measured machine the hut that is isolated relatively by park (bonnet) inside, formed a microenvironment that can accuse. Below this kind of circumstance, can choose those current model. Manufacturing process monitoring still takes seriously for company place, but pay attention to more practical in the report of the be recruited paper that gets in current annual meeting and congress read out, producing process monitoring still is a popular topic, relevant paper amounts to 6, and stem from high outside school besides 1, all come from an enterprise. Nevertheless, pay attention to more practical, is not simple apply mechanically " classical SPC " already became a trend apparently. Among them by " divine dragon car " introductory servy record gets stuck even if have a representative kind of practical kind very much. Already was assisted by this company in relief factory applies extensively at the spot to produce process quality pilot to record card to have 3 kinds: "Only cost is checked (V gets stuck) " , " attribute is checked (A gets stuck) " and " accordance is checked (F gets stuck) " . Among them before 2 kinds of analysises that are used at odd parameter, it is V only what card dogs is value of a quantity, namely metric character, and A card just does qualitative analysis. F card suits pair of multinomial parameter at the same time monitoring, dog the accordance that the public errand of these parameter defines. From the point of the characteristic of card, "Only cost gets stuck " have implementation warning function, "Attribute gets stuck " had discovered after what one is particularly good at only / bad type, and " accordance gets stuck " also be substantially one kind comfortable the A that uses at multi-parameter monitoring gets stuck. Divine dragon car assists the delegate of in relief factory points out, in producing the spot to apply actually, choose a kind of card to be used alone only rarely, except is adopted " V gets stuck + A gets stuck " mode, it is namely " V gets stuck + F gets stuck " . Undeniable, dinkum from theoretic tell, the normative practice of afore-mentioned mode and SPC is a little abhorrent it seems that, but the practice that run makes clear, not only the monitoring requirement that already can satisfy enterprise opposite basically to produce a course, and because its are simple feasible, got of the workshop be approbated generally and hope to enlarge applied limits. Tell objectively, afore-mentioned mode were reflected through only cost card realizes process monitoring, and the objective quality that blocks pair of products through attribute card, accordance has pilot a kind of thought.
