[0023] In this embodiment, the docking assembly 7 includes an expansion slot 701, which is opened on the lower side of the base 1. A movable through-hole 704 is opened in the middle of the expansion slot 701. The movable through-hole 704 is located in the middle of the shell storage platform 6. An electric push rod 702 is fixedly installed inside the expansion slot 701.

[0024] A docking sleeve rod 703 for docking with the lower end of the rotor is fixedly installed at the output end of the electric push rod 702 , and the docking sleeve rod 703 is located inside the movable through hole 704 .

[0025] The hydraulic rod 4 can be pressed to press the butt joint pressure rod 401 to make the rotor insert into the shell. In this process, in order to avoid the position deviation of the rotor, the butt joint sleeve rod 703 is lifted by starting the electric push rod 702, so that the butt joint sleeve rod 703 extends into the shell storage table 6 and is butt jointed with the currently downward moving rotor, so as to avoid the activity of the rotor. Subsequently, the hydraulic rod 4 is reset after the rotor is inserted downward, so that the operator can preinstall the upper end of the current motor. After the installation is completed, the butt joint sleeve rod 703 is retracted to release the fixation between the butt joint sleeve rod 703 and the rotor. Then the lower end is assembled. Through the above structure, the rotor can be pre-fixed, so that the rotor can be accurately inserted into the shell, and the subsequent assembly is not affected.

[0026] In the embodiment, the positioning assembly 5 includes two installation tables 501 fixedly installed on the column bodies of the two side columns 2. The upper surfaces of the two installation tables 501 are fixedly installed with sliding rails 507. The sliding rails 507 are movably installed with moving tables 5021.

[0033] When in use, firstly, the assembled shell is stored in the shell storage table 6, and the installation plate 5041 is moved by starting the second air cylinder 504, and the side plates 505 on both sides and the buffer pad 506 can stabilize the shell currently stored in the shell storage table 6;

[0034] Then, the rotor to be assembled is placed in the fixed clamping groove 5022, and then the hydraulic rod 4 is pressed to press the butt joint rod 401, so that the rotor is inserted into the shell, and at the same time, the butt joint sleeve rod 703 is extended into the shell storage table 6 by starting the electric push rod 702 to rise the butt joint sleeve rod 703, and in the process, the two side moving tables 5021 of the first air cylinder 502 are separated by starting, so that the fixing of the rotor is released, and the rotor moves downward;

[0035] After completion, the hydraulic rod 4 is reset, so that the operator can pre-assemble the upper end of the current motor, and after the assembly is completed, the fixation between the butt joint sleeve rod 703 and the rotor is released by retracting the butt joint sleeve rod 703, and then the lower end assembly is performed.

[0036] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not limited to the embodiments of the utility model.
