technical field

The utility model relates to a synchronizer production line, in particular to a mechanism for detecting the major diameter of a spline in a gear hub on the synchronizer assembly detection line.

Background technique

At present, before the gear hub and gear sleeve of the synchronizer are assembled together, a series of inspections such as the major diameter of the spline inside the gear hub, the width of the hub groove, the major diameter of the ring groove, the position of the shift fork groove of the gear sleeve, etc. are required. Inspection, all inspection operations and assembly operations after inspection are carried out manually, so each shift requires 20 people, not only the labor cost is high, the efficiency of inspection and assembly is low, but also the accuracy of inspection and assembly is difficult to guarantee, and the consistency cannot be satisfied. requirements for sexual production.

If a fully automatic production line is designed, the detection and assembly of gear hubs and gear sleeves are all carried out automatically on the production line, which will greatly improve the production efficiency of the synchronizer and ensure product quality. But how to build a synchronizer automatic production line that meets the functional requirements is a technical problem that is urgently to be solved in the industry.
