(2) In the initial state, the telescopic cylinder 34 is in a contracted state, after thrust bearings with different specifications are manually placed on corresponding step layers of the step bearing tray 51, the rotary plate 22 is rotated anticlockwise through the motor I21, so that the movable seat 31 drives the mounting cylinder 32 and the pushing component 33 to move in opposite directions by pulling the transmission plate 23, the telescopic cylinder 34 synchronously contracts or stretches, the clamping unit 4 and the motor II 53 synchronously move along with the synchronous movement, the output shaft of the motor II 53 is spliced with the head end of the screw rod 55, and at the moment, the clamping claw 41 abuts against the thrust bearing to realize external clamping and fixing of the thrust bearing.
