Description

Technical Field

[0001] This application belongs to the technical field of bearing cages, and particularly relates to a circularity detection device for welded cylindrical cages. Background Art

[0002] The cage is a very important bearing accessory with high precision requirements and is one of the important components of the bearing. Especially for precision bearings, the quality of the cage has a great impact on the bearing performance.

[0040] In the above solution, by setting the longitudinal adjustment device 3, the initial detection settings can be pre-adjusted according to the specifications of the product to be tested. Through the lateral floating device 5 and the longitudinal floating device 4, the floating roller 22 can be accurately matched with the pocket holes of the cage product to be tested to ensure the detection accuracy. And the above actions can all be automatically controlled through the control unit 7. And through the connection between the control unit 7 and the dial indicator 6, automatic reading and recording of the detection results can be realized.
