[0068] According to some embodiments of the present invention, a mechanical arm is further included, and the mechanical arm is used to transport the workpiece.

[0069] The beneficial effects of the utility model are as follows:

[0070] 1. During the production process, after the workpiece is placed on the floating tooling assembly 200, the press-fitting assembly 300 presses the workpiece. During the process, the workpiece is leveled by the leveling assembly 400 to ensure the accuracy of the press-fitting and prevent the workpiece from being crushed.

[0071] 2. After the workpiece is placed on the mounting seat 232 on the mounting plate 230, it is press-fitted by the press-fitting assembly 300 of the rotor press-fitting mechanism. After the press-fitting assembly 300 contacts the workpiece, it applies pressure downward. At this time, the mounting plate 230 moves downward and squeezes the elastic member 240. The elastic member 240 acts as a buffer, so that the support plate 220 will not be completely subjected to the same pressure. The pressure of the support plate 220 on the lower frame 100 is reduced, thereby avoiding the press-fitting assembly 300 from causing excessive pressure on the slide rail 110, the slider 222 and other components under the support plate 220, resulting in damage. At the same time, a support block 250 is also provided under the mounting plate 230. The support block 250 acts as a limiter. When the mounting plate 230 drops to a certain extent, the support block 250 contacts the bottom plate 210, thereby avoiding the elastic member 240 from being crushed.
