The working principle of the press-mounting mechanism of the end face bearing is as shown in fig. 4, the end face bearing is clamped by a manipulator from a storage bin and is placed at the upper end of a shaft, a part can stay on the conical head of the shaft due to the taper of the shaft head, but the bearing can not be flat on the shaft head but is in a skew state due to the fact that only three buckling points are supported on the conical surface, and then the steps of press-mounting the bearing are as follows:

1. the pressing mechanism is driven by a servo press at the upper end to gradually approach the bearing and the shaft from top to bottom;

2. the pressure head guide cone 10 guides the bearing, then the shaft is inserted, so that the press-fit mechanism and the shaft are basically concentric;

5. in the process of continuing to rotate, two of the end face bearings are clamped into the clamping groove step by the corresponding floating pressure heads of the large floating pressure head springs 8, the other buckle cannot squeeze the other buckle of the bearing to enter the clamping groove due to the small elastic force of the small floating pressure head springs 14 in contact with the other buckle, but the floating pressure head on the side can be tightly attached to the end face bearings all the time, and the fact that the buckle which is installed in the rotating process cannot be separated is ensured.

6.
