Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, and more specifically, to a grinding tool for small accessories. Background Art

[0002] Grinding is the process of finishing the machined surface by using abrasive particles coated or pressed on the grinding tool through the relative movement of the grinding tool and the workpiece under a certain pressure. It is an abrasive precision machining method that uses grinding tools and abrasives to grind off a very thin layer of metal from the surface of the workpiece on the basis of finishing. In the bearing manufacturing process, the inner and outer rings of the bearing are obtained by finishing and heat treatment after cutting the steel pipe to a fixed length. In the bearing ring processing process, the two cut end faces need to be ground to remove burrs in the cutting process on the one hand, and to ensure the flatness and surface smoothness of the bearing end face on the other hand.

Therefore, the entire machining process is time-consuming and it is difficult to improve the machining efficiency of the bearing ring end face.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0009] The utility model is further configured as follows: the grinding assembly includes a support frame, and the support frame is fixedly connected to the end of the U-shaped frame on the right side, two second motors are fixedly installed on the surface of the support frame, the output ends of the two second motors are fixedly connected to a rotating shaft, and the surface of the rotating shaft is sleeved with a grinding roller.

[0010] The utility model is further configured as follows: the width of the right longitudinal opening of the support frame is greater than the longitudinal length of the processing table, and the distance between the two grinding rollers is matched with the height of the bearing ring.
