With the auto industry , coordinate precision measuring its efficient and accurate advantage on a wide range of complex shape, easy to damage , deformation, less rigid , easy to introduce additional error of car parts for quality control plays a increasingly important role. The topic for the car parts coordinate precision measuring and clamping scheme flexible fixture design research . To mark a car engine cover , for example, describes a flexible fixture coordinate precision measurement in the field of car parts an application mode . Through the flexible fixture design and component parameters management , so that in response to car -shaped thin-walled parts of the coordinate precision measurement with high rigidity and clamping accuracy , more reliable and give full play to its positioning , clamping fast , the deformation error is small, the characteristics of high accuracy , after the actual use of proven, with good results . The fixture structure using Pro / ENGINEER software to design ; rich in Wuhan tricyclic Rand Co. sample processing and the actual measurement work to improve ; serialized parts of the flexible fixture parameterized for category management and calls ; completion of the fixture national invention patent applications , has now entered the stage of publicity . Programming in clamping the substrate on the basis of the product shape and the outer contour projection rules of thumb determine the product's support program , the positioning positioning rules determine the form of the product , the product of the clamping area of feasible , according to the general shape of the product All available clamping point for a regional breakdown for each area to select a suitable clamping dots clamping scheme , and ultimately determine viable positioning, support, clamping scheme ; according clamping accuracy , measuring accessibility , loading and unloading fast, clamping stability , clamping force and deformation caused by clamping rule evaluation program to determine the optimal clamping scheme , through Pro / ENGINEER software to complete the product modulus virtual fixture, and complete ball head pole sphere center coordinates of the point cloud data export .
