[0032] The working principle is as follows: The bearing to be detected is sleeved on the mounting shaft 19 and is located outside each fixing mechanism. By controlling the operation of the motor 21, the control shaft 22 rotates. At the corresponding fixing mechanism, the electromagnetic sliding fixing seat 23 slides radially and supports and fixes the clamping inner ring 2801 to drive the driving gear ring 28 to rotate. For the fixing mechanism without a bearing installed, its docking part 18 does not rotate.

[0033] For the outside of the bearing, by controlling the operation of the adjustment motor 15, the gear ring 10 rotates, causing the first gear 14 to rotate, and the first lead screw 13 and the outer clamping plate 11 move. The outer clamping plate 11 fixes the outer ring of the bearing. Then, the driving motor 5 drives the turntable 7 to rotate, causing the mounting shaft 19 to rotate, and then driving the bearing to rotate to detect the performance of the bearing.

[0034] It should be noted that when sleeving the bearing, the docking cylinder 17 can be used to control the docking of the docking part 18 and the docking valve 20.
