TECHNICAL FIELD
[0001] The present application relates to the technical field of automobile part inspection, in particular to a kind of automobile parking piece tooth piece axle assembly inspection device and its using method. BACKGROUND
[0002] In the prior art inspection of automobile parking piece tooth piece axle assembly, its dimensional accuracy and structural integrity need to be strictly detected, further to realize production quality control, so as to ensure the absolute reliability of parking system, prevent vehicle from moving unexpectedly, and ensure driving safety.
[0003] There is an automobile parking piece tooth piece axle assembly at present, which is mainly composed of shaft body and tooth piece. In actual production, the size of the part needs to be inspected to determine whether it meets the production standard and is applied. The existing inspection method is to use a three-coordinate measuring instrument to measure the angle and length of the tooth piece axle assembly. By comparing the measured size data with the standard data, it is determined whether the tooth piece axle assembly meets the production standard. However, this method has certain problems when facing mass production inspection: The three-coordinate measuring instrument is used for measurement, which is to move the probe on the X, Y and Z three perpendicular coordinate axes by manual control, accurately collect the space coordinate values of the surface points of the tooth piece axle assembly, and then fit the geometric elements and calculate the size, shape and position tolerance through computer data processing. The whole measurement and inspection process is relatively complicated. Then, the inspection is completed by comparing the measured size with the standard size.

This leads to a long measurement time for a single part and low efficiency, which cannot meet the demand of mass production inspection and delivery.
