Description

Technical Field

[0001] The utility model belongs to the technical field of bearing end surface grinding, and particularly relates to an end surface grinding device. 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. In bearing processing, the end face of the bearing frame needs to be polished. The traditional polishing method is usually manual polishing of the bearings, which is labor-intensive, time-consuming, inefficient, and has low precision.

[0003] The patent with application number 202021940573.X discloses a bearing processing end face grinding device, which relates to the field of bearing processing technology, including a base plate, a fixing frame is fixedly installed on the upper end of the base plate, and a sliding groove passing through the left and right is opened at the right end of the fixing frame. A fixing plate is fixedly welded to the middle part of the lower groove wall in the sliding groove, and a threaded rod is inserted and connected to the middle part of the fixing plate through the bearing sleeve, and the threads on the left and right parts of the outer surface of the threaded rod are reverse structures, a clamping mechanism is slidably connected in the sliding groove, and the clamping mechanism is threadedly connected to the threaded rod, and the front and rear ends of the fixing frame are fixedly installed with connecting plates, and movable plates are slidably connected to the two connecting plates.

[0004] The above technical solution utilizes two clamping plates with inner walls in a V-shaped structure that move toward each other to clamp and fix the grinding bearing. Although the inner wall of the V-shaped structure increases the contact area with the bearing during clamping compared to the traditional clamping plate, it cannot fully fit with the outer wall of the bearing, and the lead screw used for fixing is prone to loosening during the grinding process, resulting in poor stability in the bearing processing and installation. In addition, since the height of the grinding mechanism is constant, the grinding mechanism cannot contact the surface of the bearing end face after it is worn out due to grinding.
