[0020] In this embodiment, the flanging and riveting base 605 further includes a flanging head 608, a movable block 609, a switching block 606, a rivet head 607 and a support platform; The rivet head 607 is arranged in the middle of the top of the support platform, and the rivet head 607 is covered by the flanging head 608. There is a certain space between the rivet head 607 and the flanging head 608 for accommodating the sleeve. The movable block 609 is arranged below the flanging head 608 and is connected to each other. There is a space inside the support platform, and the switching block 606 is moved horizontally by an external cylinder in the space. The flanging head 608 and the movable block 609 are in contact with the switching block 606. The sleeve is pushed onto the flanging head 608 by the pressure rod 604. As the height of the switching block 606 is different, the depth of contact with the rivet head 607 is different to complete the flanging or riveting work.

[0021] The inner bottom of the flanging head 608 is designed with rounded corners.

[0022] In this embodiment, a spring connection is provided between the outer edge of the movable block 609 and the base 401 .

[0023] The spring is used to reset the height of the movable block 609 after press-fitting or riveting the workpiece, so as to facilitate the next press-fitting and riveting work.

[0024] The rotor sleeve press-fitting assembly 5 is arranged adjacent to the rotor sleeve flanging and riveting assembly 6 .

[0025] One side of the sheath loading assembly 4 is provided with a sheath feeding assembly.

[0026] Specifically, First, the sheath is placed on the sheath positioning groove 502 by the sheath loading assembly 4, the rotor is placed in the sheath by the rotor loading assembly, and then the rotor is pressed into the sheath by the rotor sheath pressing assembly 5 to form a whole. The specific structural linkage process is as follows: The sheath is transported in from the outside, and the initial position of the clamping jaws 406 is toward the sheath entry position, with the back facing the sheath positioning groove 502. The lifting plate 403 is driven to rise on the base 401 by the lifting cylinder 402, and then aligned with the sheath feeding position. The clamping jaws 406 are opened and extended into the sheath as driven by the clamping jaw cylinder 405, and then contracted and fixed, and then rotated 180° to the position facing the sheath positioning groove 502 by the rotating cylinder 404, and then the lifting plate 403 is lowered through the lifting cylinder 402 to clamp the sheath in the sheath positioning groove 502, and then the clamping jaws 406 are driven to loosen by the clamping jaw cylinder 405, and then rotated 180° back to the initial position toward the sheath by the rotating cylinder 404. The sleeve enters the position, and the purpose of transporting the sleeve to the sleeve positioning groove 502 is completed. Then, the rotor is grabbed by the rotor loading assembly. The rotor loading assembly is specifically a double-clamp manipulator 2. The manipulator 2 clamps the rotor and inserts it into the sleeve on the sleeve positioning groove 502. Finally, the bottom lifting cylinder 503 drives the receiving rod to jack up in the machine 1 to the sleeve positioning groove 502 to align the lower end of the rotor, and then the pressing cylinder 505 drives the pressing top shaft 504 to press down and align the top of the rotor to form the purpose of upper and lower alignment limit. The rotor is completely pressed into the sleeve by lifting or lowering to form a finished product. The finished product of the rotor and sleeve press-fitting is collectively referred to as "sleeve rotation 610" in the subsequent text. What is especially important is that After the sleeve 610 is formed, the sleeve 610 needs to be subjected to flanging and riveting processes. However, in the traditional process, flanging and riveting are separate processes. During the flanging and riveting processes, it is necessary to switch from flanging equipment to processing equipment, which is inefficient. In this application, flanging and riveting are combined to achieve the purpose of improving processing efficiency. The specific process steps are as follows: When the cam 608 is pressed down, the cam 609 is pressed down and the cam 609 is pressed down. Figure 6As shown, the switching block 606 is driven by an external cylinder to be inserted into the innermost side of the internal space of the support platform. At this time, the movable block 609 is pushed upward by the right side of the switching block 606, so that the sleeve 610 exerts a force on the flanging head 608. Because the bottom inner wall of the flanging head 608 is rounded, the bottom of the sleeve 610 can be deformed and flanging. In this process, because the rivet knife of the rivet head 607 does not abut against the sleeve 610, there is still a certain amount of space, which only achieves the purpose of flanging. Next, the purpose of riveting needs to be achieved. The steps are as follows: refer to Figure 7 After the flange is flanging, the pressing rod 604 rises with the movable frame 602 and the pressing cylinder 603, driving the sleeve 610 to separate from the flanging head 608 on the pressing rod 604. At the same time, the switching block 606 is pulled out with the external cylinder, so that the left low position of the switching block 606 is aligned with the left side of the movable block 609. Then, the pressing rod 604 moves down with the sleeve 610 again. After pressing against the flanging head 608, the flanging head 608 moves down with the movable block 609. At this time, because the left position of the switching block 606 is pressed against the left position of the switching block 606, the flanging head 608 moves downward with the movable block 609.
