Application of 3D Optical Measuring System in Auto Shock Absorber’s Quality Inspection

Abstract

Auto shock absorbers, with helical surfaces together with multiple punching procedures needed in manufacturing processes, make the measurement and inspection difficult. TieNiu 3DOMS is adopted to acquire their surface data, the digital point cloud data of one single vision within 10s, automatically registering complete point cloud by rotary platform, so that the efficiency of process inspection and final quality control of the work pieces of complicated surfaces are improved. Experiments show that the surface inspection precision is better than 0.05mm, and one single surface inspection within minutes.
