The manipulator 7 can be driven by a cylinder or a motor to clamp or release the rotating shaft n; the manipulator 7 is installed on a cross slide 8 to carry and pre-install the rotating shaft n; a placement frame for placing the rotating shaft n can be arranged next to the pre-installation station C (see Figure 1 ), a rotating cylinder (not shown in the figure) is installed on the back of the manipulator 7, and the rotating cylinder drives the manipulator 7 to flip, flip the horizontal rotating shaft n to the vertical direction, and put it into the center hole of the shaftless rotor m. It should be noted that the rotating shaft n can also be pre-selected to be arranged vertically, in which case there is no need for a rotating cylinder.
