[0026] Working Principle: This solution is a device for detecting the deviation of bearing rings before machining. The specific detection method is as follows: the detection probe 22 on the device is facing the clamping chuck of the lathe. When the bearing ring is clamped to the clamping chuck, the feed cylinder 10 is started, and the feed cylinder 10 drives the detection probe 22 to move and contact the outer end surface of the ring. Then, the clamping chuck is used to rotate the ring for detection.

[0027] During the test, the detection probe 22 is restricted by the ferrule, which drives the trigger screw 19 to move forward. The front end of the trigger screw 19 triggers the proximity switch sensor 12, and the indicator light 121 on the proximity switch sensor 12 is lit. When the ferrule rotates, its indicator light 121 is always on, which means that the ferrule is not misaligned.

[0028] If the indicator light 121 does not light up during the rotation of the ring, it means that the position of the detection probe 22 has changed, thereby causing a problem of installation deviation.
