[0066] (2) the chuck clamps the end plate;

[0067] (3) according to the position of the threaded hole of the end plate, the X-axis driving motor and the R-axis driving motor of the bolt mechanism are driven to move the primary positioning pin above the threaded hole of the end plate;

[0068] (4) the primary positioning cylinder is driven to insert the bolt, since the angle of the conical head of the primary positioning pin is large, it can be compatible with a larger hole deviation, and then the primary positioning cylinder is retracted;

[0072] (8) Secondary positioning cylinder retracts, motor enables and returns to home position.

[0073] The device uses a mechanical bolt to position the holes of the head plate and the end plate, preventing the hole searching deviation problem caused by the machining quality. The device can effectively avoid the head plate deviation caused by the tightening of the first group of screws.
