[0003] During the processing of the rear lower control arm of an automobile, high precision requirements are imposed on the position and dimension accuracy. To ensure that the product dimensions and spatial positions are qualified, it is necessary to inspect the product. The traditional detection method is to use a coordinate measuring machine for spatial position detection. The part to be measured is placed in its allowed measurement space, and the values of each point on the surface of the part to be measured at different coordinate positions in space are accurately measured. Then, through computer processing, measurement elements such as circles, spheres, cylinders, cones, and curved surfaces are fitted, and geometric measurement data such as shape and position tolerances are obtained through mathematical calculations.

[0004] This detection method requires programming first, then positioning the product, and then measuring the product according to the program. After the product is detected, a report is generated, and then it is analyzed whether the report is qualified. The detection steps are complex, which prolongs the detection time, reduces the detection efficiency, and increases the detection cost. Summary of the Utility Model
