[0023] Specific implementation and principle:

[0024] During the inspection, the bearing to be inspected is placed in the fixed seat 2, and the outer ring of the bearing is fixed to the fixed seat 2 by the top screw, then the plug shaft 35 is inserted into the bearing, and the inner ring of the bearing is fixed to the plug shaft 35 by the top screw, and the plug shaft 35 is rotated so that the level meter 36 on it displays a horizontal state, which is convenient for the subsequent engagement between the driving gear 1 33 and the driving gear 2 351, and then the driving motor 41 is started, and the pulley 1 42 on the output shaft of the driving motor 41 drives the pulley 2 44 and the rotating shaft 1 31 to rotate through the driving belt 43, so that the driving gear 1 33 rotates, and at the same time, the bevel gear 1 311 on the rotating shaft 1 31 drives the rotating shaft 2 32 and the bevel gear 2 321 to rotate, so that the driving disk 39 on the rotating shaft 2 32 rotates accordingly, and the concave arc surface on the driving disk 39 The roller 343 in 391 moves along the surface of the driving disk 39, pushing the moving plate 34 forward. When the driving gear 1 33 meshes with the driving gear 2 351 on the plug shaft 35, the plug shaft 35 is driven to rotate. The plug shaft 35 causes the inner ring of the bearing to rotate, and the roller 343 rolls along the surface of the driving disk 39 to keep the driving gear 1 33 and the driving gear 2 351 in a meshing state. When the roller 343 moves to the bottom of the concave arc surface 391 of the driving disk 39, the output shaft of the driving motor 41 stops rotating.
