Description

Technical Field

[0001] The utility model relates to the technical field of bearing production, in particular to a grinding device for bearing production. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy.

[0003] During the production of bearings, burrs and deviations will occur on both the inner and outer sides of the bearings. Therefore, a grinding device is required to grind the inner and outer sides of the bearings. Currently, the following problems exist in the process of using a grinding device to grind the inner side of the bearing:

[0004] First, when the bearing is clamped and positioned using a fixture, the centering and positioning effect cannot be achieved, thereby reducing the positioning accuracy of the bearing, making it inconvenient for the grinding device to grind, and affecting the grinding efficiency;

[0005] Secondly, when the grinding wheel is grinding the inner side of the bearing, it cannot move up and down, so it can only grind an area on the inner side of the bearing. This makes it impossible to fully and evenly grind the inner side of bearings of different thicknesses, thereby reducing the grinding quality. Utility Model Content
