[0027] Please refer to Figure 1 and Figure 2 The upper surface of the U-shaped frame 3 is placed with the bearing body 4, and the inner ring surface of the bearing body 4 is abutted with one side of the limiting pad 10, the inside of the workbench 1 is provided with the electric rotating disc 2, the top of the electric rotating disc 2 is fixedly connected with the bottom of the U-shaped frame 3, through the use of the electric rotating disc 2, the synchronous rotation of the bearing body 4 fixedly limited can be driven, that is, the corresponding cleaning and detection operation can be carried out.

[0028] The working principle is that when the bearing body 4 is positioned and fixed, the bearing body 4 is placed on the upper surface of the U-shaped frame 3, then the first servo motor 6 is driven by the power of the first servo motor 6 to rotate the gear 7 fixedly connected to the outer surface of the output shaft of the first servo motor 6.

Then, through the concave-convex degree of the outer ring surface of the bearing body 4, the extrusion pad 20 changes, and the change is sensed by the pressure detector 21 fixedly installed on the upper surface of the extrusion pad 20, so that the outer ring surface of the bearing body 4 is detected.
