The power of the engine is transmitted to the wheels through the movable end joint, the intermediate shaft and the fixed end joint, so that the wheels are driven to rotate. The fixed end section mainly comprises a bell-shaped shell, an star-shaped sleeve, a retainer and a steel ball. In the high-performance transmission shaft with high transmission efficiency, large swing angle, light weight and low noise, eight inner ball tracks are arranged on the bell-shaped shell of the fixed end section, and each ball track is sequentially formed by two circular arc sections with different curvatures and one straight line section; the bell-shaped shell requires measurement and grouping of the distance between diameters corresponding to the center point of the ball channel, so that the bell-shaped shell is assembled with steel balls with corresponding sizes and eight ball channel star-shaped sleeves in a matched mode, and reasonable gaps among the pieces are guaranteed. The diameter corresponding to the ball channel center of the eight-ball channel bell shell is critical to the performance influence of the fixed end joint, if the diameter corresponding to the ball channel center of the bell shell is not accurately measured, the function test of the assembled fixed end joint is unqualified after assembly, the problems of reduced transmission efficiency, serious abrasion, shortened service life and the like can occur, even the assembly problems of clamping stagnation, abnormal sound, small swing angle and the like of the fixed end joint occur when a host factory is offline, the risk of shutdown or recall of the host factory exists, and the user satisfaction degree is reduced.

The qualified bell housing is selected again for assembly, so that the assembly efficiency of the transmission shaft is low, parts such as a clamp, a steel ball, lubricating grease, a rubber cover and the like of the fixed end joint after disassembly are all scrapped, serious waste of materials and materials is caused, and the production cost is increased; once the transmission shaft provided with the disqualified eight-lane bell housing is shipped to a user side, abnormal sound phenomenon can occur after the transmission shaft is used for a period of time, even if the transmission shaft is assembled on the site of the user, the phenomenon that a host factory stops line can not be assembled, so that the user returns goods or claims, and huge losses are caused for units.
Therefore, in the eight-lane bell housing processing field, there is a need for an automated device capable of detecting and grouping the center-to-center distances of the lanes thereof, instead of the three-coordinate detection method with low efficiency, so as to realize that the eight-lane bell housing can meet the severe requirement of rapidly inspecting and grouping piece by piece along with the production line.
