Description

Technical Field

[0001] The utility model relates to the technical field of cage processing, in particular to a cage deburring device. Background Art

[0002] The cage, also known as the bearing cage or bearing retainer, is an important part of the bearing. It partially wraps all or part of the rolling elements and moves with them. It is mainly used to isolate the rolling elements and usually guides the rolling elements and keeps them in the bearing.

[0003] In the production process of cages, deburring is a very important step. The burrs on the cages not only affect the appearance quality of the product, but may also cause noise, vibration or wear during use. The burrs will damage the contact surface between the cage and other components, reducing its motion performance and stability. The burrs on the cages will also affect the assembly accuracy and cause the bearing performance to deteriorate.

[0004] The Chinese utility model patent with the patent number CN202322587546.9 discloses a clamping device for deburring a bearing retainer, which belongs to the technical field of retainer processing. It includes a fixed seat, the number of which is two, and a limiting groove is provided on the side of the fixed seat. Two limiting blocks are slidably connected in the limiting groove, and the opposite surfaces of the corresponding two limiting blocks are respectively connected to the two ends of the first elastic telescopic rod, and the two limiting blocks on the left are threadedly connected with the same bidirectional screw. The first elastic telescopic rod, the second elastic telescopic rod and the limiting wheel of the above structure have the effect of clamping and positioning the retainer, but they need manual placement and manual adjustment, which is not convenient for loading and unloading the retainer when removing burrs.
