Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to an end surface supporting device used for bearing processing. Background Art

[0002] A bearing is a workpiece that supports a rotating shaft and reduces the friction of the rotating shaft. During the processing of the bearing, the inner and outer rings and balls need to be pre-processed, and then the balls are assembled between the inner and outer rings. In addition, the circumferential surface of the bearing needs to be polished to make the surface of the bearing smoother. During this process, the bearing needs to be fixed by an end face support device to facilitate the grinding of the bearing.

[0003] The Chinese utility model patent with application date of 2021-06-09 and publication number CN214922468U discloses an end face support device for bearing processing, including a base plate, a support plate is fixedly installed at the end of the base plate, a circular groove is opened on the side wall of the support plate, and a movable column is movably installed on the inner wall of the circular groove, and the movable column is movably arranged inside the circular groove, and a clamp is fixedly installed on the end of the movable column away from the support plate, and an offset structure is formed between the two clamps. The connecting column is located in the middle of the two clamps, and a compression spring is fixedly installed on the side of the clamp opposite to the support plate. The compression spring is movably sleeved on the surface of the movable column, and the front end of the base plate is symmetrically provided with the same structure as the rear end of the base plate. A fixing mechanism is fixedly installed on the end of the base plate, and the fixing mechanism includes a vertical rod, and the vertical rod is fixedly installed on the side opposite to the base plate. A connecting column is fixedly installed on the end of the side wall of the vertical rod, and a movable disk is sleeved on the surface of the connecting column, so that the device can support and fix the outer end of a bearing of any size when in use, and the fixing effect is good.

[0004] In this technical solution, the bearing is clamped from the outside by a clamp that is offset up and down, and is clamped from the inside by a rubber ring and a compression spring. However, when the bearing is subjected to pressure in the axial direction, it is difficult for the clamp and the rubber ring to limit the bearing, which can easily cause the bearing to move and affect the fixing effect of the bearing. Further improvements can be made. Utility Model Content
