[0002] A bearing is a mechanical element for limiting relative movement within a required movement range and reducing friction between movement parts.

[0003] There are many types of bearings, and the roller bearing is one of the more common types. The roller bearing is different from other bearings in that the rollers inside the roller bearing are in a cylindrical structure, and the roller bearing has good precision and rigidity. Before assembly, the rollers need to be ground to reduce the friction coefficient. At present, when the roller bearing rollers are ground, the two ends of the rollers are usually clamped by a clamping mechanism, and the rollers are driven to rotate, and the rollers are ground by cooperating with a grinding device. This processing method is relatively single, and the efficiency is poor. Single operation can only grind one roller. When processing a large number of rollers, it cannot meet the production needs. At the same time, the conventional roller grinding device can only grind the outer arc surface of the roller.

When the clamping module 8 drives the roller to ascend, the top edge of the roller will be in contact with the inclined grinding block 28, and the top edge of the roller can be ground. When the clamping module 8 drives the roller to continue to ascend, the extended push telescopic rod 29 is retracted to drive the grinding block 28 to reset to a vertical state, so that the roller can pass smoothly. When the clamping module 8 drives the roller to ascend above the grinding block 28, the telescopic end of the push telescopic rod 29 below the grinding base 27 is extended to push the grinding block 28 to be inclined in the opposite direction.
