Technical Field

[0001] The utility model relates to the field of bearing processing, and particularly relates to a positioning tooling for the processing of double-row ball bearings. Background Technique

[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy. According to the different friction properties of the moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. During the bearing processing and grinding process, it is necessary to grind the upper and lower end faces of the bearing components flat. A double-row ball bearing refers to a bearing in which two rows of ball bearings are fitted on the outer side of the bearing inner ring for rolling.

[0003] In the traditional method, it is necessary to perform different positioning and clamping on the bearing outer ring or inner ring respectively according to the processing position requirements before processing, which is rather troublesome.

[0012] The technical effects and advantages of the present utility model:

[0013] 1. In the actual operation of the present utility model, the bearing can be sleeved outside a plurality of elastic arc plates.

The sponge pad can play a buffering and protective role. Further, after the driving motor is started, the inner ring of the bearing can be driven to rotate through the tripod, which is convenient for the grinding mechanism to grind the upper end surface of the inner ring of the bearing. At the same time, when the inner ring of the bearing rotates, the sponge pad will clean the outer side of the inner ring of the bearing to avoid the adhesion of grinding debris on the outer side of the inner ring of the bearing, which is convenient for subsequent fitting with the outer ring of the bearing.
