Laser dogs appearance makes medium application in the car

3kg, the gross weight after the light tripod of the form a complete set on join also does not exceed 20kg, can install conveniently go up in product line. Laser of graph 1 LTS1100 dogs appearance appearance laser dogs the outfit attune that a representative application of appearance is clamping apparatus of tool of solder outfit workshop. Outfit of solder of white automobile body is whole car one of the most important segment in making, the actor bad of solder outfit quality not only concern follow-up general assembly whether on the rails, affect the intensity of whole automobile body and security more likely to the car, and solder outfit quality depends on directly again the fixed position precision of solder outfit clamping apparatus. Before, go to work of car product line installs the initial installation of clamping apparatus to locate, it is to make car of a model first commonly, model car precision passes stationary 3 coordinate are measured machine will assure. Model car is placed in labour on, adjust collet position to make each working face and model car joint good, the action that appearance bar passes in measuring reached since this model car actually. Had adjusted through model car after each collet positions, the spot with relatively inferior level of this kind of precision measures reoccupy joint arm equipment undertakes answer measure examine. Articulatory arm measures range very small, the station is measured impossibly in in measure automobile body the one Kong Yi chamfer with original standard fixed position locates 3 times face, so original coordinate department often needs to pass 1 ～ 2 times to move the station will build. Accordingly, include necessarily in the fiducial coordinate department that builds through articulatory arm place move station error, this was restricted directly answer measured precision level, cannot assure the relative position precision inside big range. In addition, as a result of the limitation on its principle, articulatory arm is real service life is quite short. The use that passes period of time or unused hind, of joint position bearing wear away and of brachial body be out of shape can bring about its precision drop badly, and this kind of precision drops is cannot compensatory. Because of afore-mentioned reasons, solder installs the fixed position precision of clamping apparatus to rely on model car precision greatly essentially, but model car uses the deadliest weakness as appearance club is its are out of shape easily. Model car itself is the white automobile body with higher level of a precision only, spare parts of a housing, although pass stationary,3 coordinate are measured machine detect eligible, but shipping in the spot and process of follow-up outfit air waiting for element happening to be out of shape as a result of action of temperature change, outside force is uncertain, this part error will become solder to install the fixed position error of clamping apparatus directly. If use laser to dog appearance, be in above all bigger measure do not need to move inside limits station, can assure relatively the fiducial coordinate of high accuracy is (the precision inside 5m is ± 0.

025mm) . Having this accurate fiducial coordinate is, guide can be with automobile body digital-to-analogue directly after mathematical model more fiducial than be opposite will adjust range of clamping apparatus fixed position. Because clamping apparatus locates locate the academic digital-to-analogue of the face is of coincide on the academic digital-to-analogue of the face and automobile body, need not measure for clamping apparatus so found digital-to-analogue technically. After building fiducial coordinate to fasten, the face of clamping apparatus fixed position that puts target ball in need adjustment (fixed position is sold) on, coordinate of center of ball of target of software plan cipher out arrives fixed position face (fixed position is sold) the umbriferous distance of digital-to-analogue, make compensation computation get the direction of 3D deviation and numerical value according to target ball radius, real time shows go up in computer screen, observe and adjust till this deviation arrives inside tolerancepublic errand limits. After using this kind to measure craft, depend on model car precision no longer, the intermediate segment that reduced an error to deliver, saved the cost that make and measures model car at the same time, the advantage is clearly. Laser dogs appearance itself regards length as the standard from the laser interferometer of the belt with its, grating is piled up dish as angle standard, a series of calibration programs that adopt oneself are OK maintain high accuracy from beginning to end in cycle of whole product life. Normally, the API laser that be used in fixed work place and deposits dogs appearance does the cycle from calibration to be able to be as long as a few months, and the time that spends from calibration place also does not exceed 10min. API company is laser dogs not only the contriver of appearance, and still be in roll out new patulous technology ceaselessly. Traditional laser dogs the biggest challenge that measures a technology to be encountered in automobile industry is the issue that radial block decides, and the solution that this one difficult problem had two effective now: Technology of absolutely range finding (ADM) and intelligence measure head technology (Itelliprobe) . Traditional laser dogs because appearance uses the principle that laser interferes to measure target ball to arrive dog the distance of the head, ask the light between laser head and target ball cannot be broken by block, and often assure very hard at this o'clock when measuring car tool clamping apparatus. The technology of absolutely range finding of API allows to dog the process interrupts the light, can put target ball to target position to will dog again next directly even the head points to target ball to undertake metrical. This is one kind is based on reflex of infra-red smooth pulse to pat frequency enumerated technology of absolutely range finding, the precision inside its 10m can be as high as 0.

02mm. This technology is in online detect car clamping apparatus repeats effect of side of fixed position precision first-rate. Normally we install optical target on mobile collet, every time after collet reachs working place, software drive dogs an academic position that points to optical target, actual every time the position with located collet deviate theory position, dog the head will be all round academic position with corkscrewed yarn contrail motion searchs optical target, technology of absolutely range finding measures the reoccupy after the lock decides a goal give optical target to arrive dog the distance of the head, calculate thereby a real position with right now located collet. In software cooperate to fall, laser dogs appearance can be inside cutty time (need a few seconds only normally) measure those who give many collet to repeat fixed position precision, and precision far outclass is based on digital camera hand in collect take a picture measure a technology. Nextpage is additional, the TrackerIIPlus of API still supports a kind of intelligence to measure head technology, intelligence measures a head is a kind of special optical target (see a picture 2) , bottom can amount to the measuring staff of hundreds of millimeter of length, smooth target installs the top that measuring a head. Intelligence measures an in-house and compositive sensor to be able to feel intelligence to measure a head to change at the stance part of laser beam relatively, the coordinate cost that passes topmost and optical target and stance part computation give the coordinate with bottom most advanced measuring staff to be worth, can use surveying rod so most advanced the workpiece the reverse side that goes measuring laser illuminate to be less than and deeper aperture and chamfer. Graph 2 intelligence measure head laser to dog appearance offerred those who abound to propose coordinate way, besides the tradition building the coordinate, face that choose a route to build coordinate, much dot to plan to add up to coordinate at 3 o'clock is to wait for means beyond, still offerred a kind distinctive complex plan to close propose coordinate way. Aperture of this kind of aleatoric curved surface that builds coordinate means to allow to use workpiece to go up, planar, fixed position, fixed position nods combination to rise as what build coordinate fiducial, drafting coordinate of workpiece of aggregate cipher out is (see a picture 3) . The surface that chooses proper datum plane to go up on the workpiece maths model that guides above all is nodded (the fixed position face on corresponding tool) with fiducial aperture center (the fixed position on corresponding tool is sold) , next ordinal these fiducial element places that measure workpiece to go up, get planning to combine computational result. If fixed position is standard,had attributed fixed position, can know through analytic result data fiducial between what does existence conflict, is fiducial (through abandoning certain plan to add up to computation to restrain a condition to come true) , this kind complex plan to add up to the function that builds coordinate to make laser dogs appearance can replace all sorts of machinist to install check to provide will detect white automobile body and stamping workpiece. Secure good part above all, choice tool check provides the fixed position element when detecting (include to locate face and fixed position are sold) consult as what build coordinate fiducial. Such drafting that add up to gotten workpiece coordinate is accurate emersion mechanical check provides the workpiece coordinate that when detecting, uses is. Measure the workpiece error that give and mechanical check to provide right now detect the deviation data that give is consistent, the actual condition of workpiece of can accurate report. This is so called " electronic tool " technology. Those who build coordinate is fiducial the installation fixed position with real work is standard or working radical keeps consistent definitely, of such ability utmost reduce the error that measures coordinate chalaza to come. Use this kind to be based on mathematical model " electronic tool " technology, saving while production machinist holds cost of high specified number also leave out the labor power that has detect and be maintenanced to these mechanical tool is devoted, improved manufacturing efficiency greatly. Graph 3 choosing to plan to add up to coordinate on workpiece digital-to-analogue is fiducial in addition, laser dogs appearance also can be used at car appearance design. Laser dogs the mathematical model that the way of dynamic scanning work of appearance form diversity can beg curve of the freedom between clean, curved surface accurately instead, the production that reduces punch mould greatly thereby makes cost, make laser dogs appearance also can use at these punch moulds and workpiece detect. Laser dogs appearance laser dogs appearance measures equipment as the 3 coordinate with a kind of portable high accuracy, to automobile manufacturing industry, not be a strange thing. Be in Europe, beautiful - Xue Tielong Motor Corporation and Reynolds Motor Corporation had used company of engineering of American automatic nicety in great quantities (Automated Precision Inc.

, abbreviation API company) TrackerIIPlus laser of production dogs appearance, replace the other spot such as articulatory arm to measure equipment. Be in China, shanghai is general the TrackerIIPlus laser that also had chosen two API company dogs appearance, the tool that is used at producing the spot detects and the measurement of white automobile body and stamping workpiece.
