Description

Technical Field

[0001] The present application relates to the field of needle roller bearing processing, and in particular to a needle roller bearing processing device. Background Art

[0002] Needle roller bearings are roller bearings with cylindrical rollers. Relative to their diameter, the rollers are both thin and long. This type of roller is called a needle roller. The manufacturing process of needle rollers is as follows: blank forming → deburring → heat treatment → rough, fine and final grinding of rolling surfaces → super finishing of rolling surfaces or sawdust polishing.

[0003] During the processing of existing needle roller bearings, processing personnel need to deburr and heat treat the needle roller blank to form a prototype of the needle roller bearing. Processing personnel are required to comprehensively grind the needle roller bearing to further deal with the burrs on its surface. During the grinding process, processing personnel need to transport several needle rollers into the grinding mechanism. The falling positions of the needle rollers are different, resulting in some needle roller surfaces not being grinded. Therefore, processing personnel often need to use needle roller bearing processing equipment during the processing of needle roller bearings.

[0004] Existing needle roller bearing processing equipment needs to deburr and heat treat the needle rollers. When the processing personnel process the rough, fine and final grinding of the rolling surfaces of the needle rollers, they usually place the needle rollers to be processed directly inside the grinding box, which causes the needle rollers to fall unevenly and some of the needle roller surfaces cannot be ground, reducing the grinding efficiency of the needle rollers inside the needle roller bearings. Utility Model Content
