Description

Technical Field

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

[0002] Bearings are important components in mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Rolling bearings are generally composed of four parts: an outer ring, an inner ring, rolling elements, and a cage. Raceways are usually provided on the inner ring wall of the outer ring and the outer ring wall of the inner ring for mounting rolling elements and providing space for the rolling elements to run. When processing the raceway of the bearing, a grinding device for the inner ring raceway of the bearing is required.

[0003] Some bearing inner ring raceway grinding devices currently on the market: for example, the utility model patent with authorization announcement number CN220240917U discloses a bearing inner ring raceway grinding device, which solves the problem that the same grinding device cannot grind the bearing raceway with increasing precision by setting a tripod, a grinding wheel, a polishing wheel, a fine polishing wheel, a square frame, and a rotating motor; first, the corresponding grinding wheel is brought into contact with the raceway of the inner wall of the bearing to be ground, and is rotated for grinding, while the bearing to be ground itself is clamped by a clamping plate, and the rotating motor is used to grind the bearing. The machine can drive the clamping rod to rotate, and the bearing to be ground rotates synchronously, so as to grind the raceway in the bearing to be ground, and then replace the polishing wheel and fine polishing wheel with higher precision for further grinding, so that the raceway is smoother and the grinding process is achieved quickly. However, when switching between the grinding wheel, polishing wheel and fine polishing wheel, it is necessary to remove the limit bolt and rotate the tripod. After switching between the grinding wheel, polishing wheel and fine polishing wheel, the limit bolt should be installed to fix the tripod, which is troublesome and inconvenient to switch.
