[0023] Optionally, a guide surface is provided at the end of the inflation piston protruding from the cover plate, and the guide surface is in the shape of a circular arc protrusion. The guide surface can abut against the plate surface and guide the inflation piston to slide in a direction close to the inflation flow channel.

The clamping assembly 2 is installed on the top surface of the base 1. The clamping assembly 2 can clamp the rotor and drive the rotor to be coaxially embedded in the stator inner cavity, so that the rotor is not easy to fit the stator inner cavity wall under the magnetic attraction of the stator, thereby reducing the difficulty of assembling the stator and the rotor, and improving the assembly efficiency of the stator and the rotor, thereby ensuring the assembly accuracy of the stator and the rotor, shortening the assembly cycle of the stator and the rotor, and reducing the assembly cost of the stator and the rotor.

The elastic member three 57 has the elastic force to drive the clamping plate 55 to slide in the direction close to the cover plate 51, and the surface of the clamping plate 55 is pressed against the surface of the cover plate 51, and the cover plate 51 is limited in the limiting cavity 31.

[0042] Reference Figure 3 and Figure 4 When the surface of the cover plate 51 is flush with the top surface of the fixing block 243, the elastic force of the elastic member 3 57 drives the clamping plate 55 to slide toward the direction close to the cover plate 51, and the surface of the clamping plate 55 presses against the surface of the cover plate 51, making it difficult for the cover plate 51 to rotate in the limiting cavity 31, thereby improving the limiting stability of the cover plate 51 in the limiting cavity 31.

[0043] Reference Figure 3 and Figure 4 An elastic airbag 6 is embedded in the surface of the cover plate 51 facing the limiting cavity 31. The material of the elastic airbag 6 can be rubber or silicone. In the embodiment of the present application, the material of the elastic airbag 6 is rubber, which has a certain deformation ability. The surface of the elastic airbag 6 can press against the surface of the base 4 and limit the base 4 in the limiting cavity 31. At the same time, the elastic airbag 6 is deformed by the pressure of the base 4, reducing the wear between the cover plate 51 and the base 4, thereby improving the production quality of the motor.

[0044] Reference Figure 3 and Figure 4The cover plate 51 is equipped with an inflatable component 7, which can inflate the inner cavity of the elastic airbag 6. The inflatable component 7 includes an inflatable piston 71 and an elastic member 72. The material of the inflatable piston 71 can be rubber or silicone. In the embodiment of the present application, the material of the inflatable piston 71 is rubber, which has a certain deformation ability. The cover plate 51 is provided with an inflatable flow channel 511 for the inflatable piston 71 to slide toward the plate surface of the abutting plate 55. The sliding direction of the inflatable piston 71 is parallel to the height direction of the base 1. The elastic member 72 can be a compression spring or a tension spring. In the embodiment of the present application, the elastic member 72 is a compression spring with a certain deformation ability. One end of the elastic member 72 in the elastic direction is fixed on the inner wall of the inflatable flow channel 511, and the other end of the elastic member 72 in the elastic direction is fixed on the surface of the inflatable piston 71. The elastic member 72 has the tendency of elastic force driving the inflatable piston 71 to slide in the direction away from the inflatable flow channel 511, and the end of the inflatable piston 71 protrudes from the plate surface of the cover plate 51.

[0045] Reference Figure 3 and Figure 4 The end of the inflation piston 71 protruding from the cover plate 51 is provided with a guide surface 711, and the guide surface 711 is in the shape of a circular arc protrusion. The guide surface 711 can abut against the surface of the clamping plate 55 and guide the inflation piston 71 to slide in the direction close to the inflation channel 511. The surface of the clamping plate 55 is provided with an inflation groove 551 for the end of the inflation piston 71 to be embedded in the inflation channel 511; when the clamping plate 55 slides in the direction close to the cover plate 51 and the inflation groove 551 is connected to the inflation channel 511, the elastic force of the elastic member 72 drives the inflation piston 71 to slide in the direction close to the inflation groove 551, and the end of the inflation piston 71 is embedded in the inflation groove 551. Inside, the outer peripheral surface of the inflation piston 71 presses against the inner wall of the inflation groove 551 to form a limit, so that the clamping plate 55 is not easy to deviate in the sliding cavity 561, thereby improving the clamping force between the clamping plate 55 and the cover plate 51; at the same time, the inner wall of the inflation groove 551 presses against the end of the inflation piston 71 and drives the inflation piston 71 to slide toward the inflation flow channel 511, and the air in the inflation flow channel 511 enters the inner cavity of the elastic airbag 6, and the surface of the elastic airbag 6 is pressurized and expanded and presses against the surface of the base 4 to form a limit, so that the base 4 is not easy to deviate in the limit cavity 31, thereby improving the assembly accuracy between the stator and the rotor.

[0046] The implementation principle of the rotor and stator assembly machine with a traction device in the embodiment of the present application is as follows: the base 4 is embedded in the limiting cavity 31, the end of the rotating shaft 8 is embedded in the positioning hole 235, the adjusting cylinder 22 drives the positioning block 23 to slide, the rotor axis and the stator axis coincide, the positioning cylinder 242 drives the fixing block 243 to slide in the direction close to the positioning rod 26, the end of the positioning rod 26 is embedded in the slide groove 2431, and the axis of the positioning hole 235, the axis of the stator and the axis of the fixing hole 2432 coincide, and the sliding seat 21 moves along the slide rail 25 toward the direction close to the positioning rod 26. The limit seat 3 slides in the direction, driving the positioning rod 26 to slide on the inner wall of the slide groove 2431, and the rotor is coaxially embedded in the positioning cavity. At the same time, the end of the rotating shaft 8 away from the positioning block 23 is embedded in the fixing hole 2432, and the circumferential outer wall of the rotating shaft 8 is pressed against the inner wall of the fixing hole 2432 to form a limit. The fixing block 243 and the positioning block 23 support both ends of the rotating shaft 8, so that the rotor is not easy to deviate in the stator cavity, thereby improving the assembly accuracy between the rotor and the stator, shortening the assembly cycle of the stator and the rotor, and thus reducing the assembly cost of the stator and the rotor.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
