Technical Field

[0001] The utility model relates to the technical field of bearing fixtures, in particular to a bearing fixture for automatically pressing bearings. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearings often need to be press-fitted during the production and processing process. During press-fitting, the bearings need to be clamped and fixed by a fixture.

[0003] Application number: CN202222567508.2 discloses a bearing fixture for automatically pressing bearings, including a base, a positioning support ring is fixedly installed in the middle of the outer surface of the upper end of the base, a limiting ring is fixedly installed on the outer wall of the outer surface of the upper end of the positioning support ring, and a clamp assembly is fixedly installed on the left and right sides of the outer surface of the upper end of the base, and the clamp assembly includes a first transmission box, a second transmission box, a servo motor, an arc splint, a movable rod, an anti-slip pad, a slide groove, a guide rod, a sliding sleeve, a ball nut, a connecting rod, a ball screw, a worm, a rotating shaft and a worm wheel, and the first transmission box is fixedly installed on the left and right sides of the outer surface of the upper end of the base, and the second transmission box is fixedly installed on one side of the outer surface of the first transmission box.

[0004] The above patented technology drives the movable rod with the arc-shaped clamping plate to clamp the bearing for automatic press-fitting through the screw structure in the transmission box. However, the clamping size of the bearing ring body of this arc-shaped clamping plate is greatly limited. The size of the bearing ring body that can be clamped is greatly limited by the arc opening of the arc-shaped clamping plate. In addition, the driving structure of the arc-shaped clamping plate is relatively complicated. The maintenance and disassembly cost after damage is high, which cannot meet the economic clamping requirements during automatic press-fitting of bearings. For this reason, we propose a bearing fixture for automatic press-fitting of bearings. Utility Model Content
