The lifting device 10 includes a lifting plate 11 and a lifting driving assembly 12, and the lifting plate 11 is connected to the lifting driving assembly 12.
The lift driving assembly 12 includes at least one lift member 121, and at least one link member 122, the lift member 121 is implemented to include a cylinder, the lift member 121 is fixed at a designated vertical position, the link member 122 is connected to the lift member 121 to be vertically movable up and down, and the link member 122 is connected to the lift plate 11. The lifting member 121 drives the link member 122 to move up and down, and further drives the lifting plate 11 to move up and down.
Preferably, at least two lifting elements 121 are provided, the lifting elements 121 may be implemented as threaded rods extending vertically from bottom to top, the link element 122 may be implemented as a threaded sleeve connected to the lifting plate 11, and the link element 122 is fixedly connected to the lifting plate 11. Each lifting element 121 is coaxially and threadedly sleeved with one of the link elements 122.
The lifting plate 11 is connected to the plurality of lifting members 121 via the plurality of links 122, respectively, so that the lifting plate 11 is restricted to move only up and down, and the links 122 are also restricted to move only up and down but not to rotate axially. When the lifting member 121 rotates axially, the link member 122 moves up and down in the vertical direction relative to the lifting member 121, so as to drive the lifting plate 11 to move up and down vertically together.
When the lifting plate 11 moves up and down, the upper surface of the lifting plate 11 is kept horizontal, and the integrated shell 600 is detachably and fixedly mounted on the upper surface of the lifting plate 11, so that the lifting plate 11 can drive the integrated shell 600 mounted thereon to vertically move up and down.
The rotor positioning device 20 is fixedly installed above the lifting plate 11, and the rotor positioning device 20 is detachably connected to the rotor shaft of the motor rotor 500 to detachably fix the motor rotor 500 above the lifting plate 11.
When the lifting plate 11 moves to the lowest position, the distance between the upper surface of the lifting plate 11 and the lower end surface of the rotor positioning device 20 is greater than the sum of the heights of the motor rotor 500 and the integrated housing 600, so that when the motor rotor 500 and the integrated housing 600 are respectively fixed to the rotor positioning device 20 and the lifting plate 11 moves to the lowest position, the motor rotor 500 and the integrated housing 600 are in a separated state, and the motor rotor 500 and the integrated housing 600 are not influenced by each other before being in butt joint assembly.
After the motor rotor 500 and the integrated housing 600 are respectively fixed to the rotor positioning device 20 and the lifting plate 11 that moves to the lowest position, and the integrated housing 600 is set in a state where the rotor insertion port 6002 faces the motor rotor 500, the lifting driving assembly 12 may drive the lifting plate 11 to move upward until the integrated housing 600 is pushed to a position where it is butt-assembled with the motor rotor 500.
It should be noted that the rotor positioning device 20 is installed outside the range of the path where the lifting plate 11 moves up and down, so as to prevent the rotor positioning device 20 from affecting the lifting plate 11 to push the integrated housing 600 to lift, so that the integrated housing 600 can be lifted smoothly and assembled with the motor rotor 500 in a butt joint manner.
After the integrated housing 600 is assembled with the motor rotor 500 in a butt joint manner, the rotor positioning device 20 is separated from the rotor shaft of the motor rotor 500, and after the lifting plate 11 moves and descends to the lowest position, a user can detach the assembled electric drive assembly 700 from the lifting plate 11.

In this way, the fool-proof member 30 can prevent the lifting plate 11 from being out of control and continuously rising after the integrated housing 600 and the motor rotor 500 are butt-jointed and assembled, so as to prevent the lifting plate 11 from being out of control and lifting to damage the integrated housing 600 and the motor rotor 500, and thus the device can run more safely.
Before the butt joint assembly, a user only needs to fix the motor rotor 500 above the lifting plate 11 through the rotor positioning device 20, and then fix the integrated housing 600 on the lifting plate 11 with the rotor inlet 6002 facing the position of the motor rotor 500. The electric motor rotor butt-joint assembling apparatus can butt-joint assemble the integrated housing 600 and the electric motor rotor 500 by simply vertically lifting the lifting plate 11, and the integrated housing 600 can be kept stable on the lifting plate 11 when being pushed to lift by the lifting plate 11 due to its own weight. The position of the motor rotor 500 is not changed in the whole butt-joint assembling process, expensive equipment for accurately controlling the movement of the motor rotor 500 is not needed, and the setting cost of the motor rotor butt-joint assembling equipment is greatly reduced.

The integrated housing 600 is mounted on the lifting plate 11, and after being sleeved outside the rotor positioning device 20, the motor rotor 500 is mounted on the rotor shaft connector 22. After the motor rotor 500 is installed, the lifting plate 11 is driven by the lifting drive assembly 12 to lift, and then the integrated housing 600 is driven to lift to a position where it is butt-jointed and assembled with the motor rotor 500.
