[0057] Specifically,

[0058] First, the sheath is placed on the sheath positioning groove 502 by the sheath feeding assembly 4, the rotor is placed in the sheath by the rotor feeding assembly, and then the rotor is pressed into the sheath by the rotor-sheath pressing assembly 5 to form a whole, wherein the specific structure linkage process is as follows:

[0059] The sheath enters from the outside, the initial position of the clamping jaw 406 is towards the sheath entering position, the back is towards the sheath positioning groove 502, the lifting plate 403 is driven to rise on the base 401 by the lifting cylinder 402, and then aligns with the sheath feeding position, the clamping jaw 406 is driven to open and extend into the sheath by the clamping jaw cylinder 405, and then is fixed by contraction, and then is rotated by 180° to the position towards the sheath positioning groove 502 by the rotating cylinder 404, and then is lowered by the lifting plate 403 by the lifting cylinder 402 to clamp the sheath in the sheath positioning groove 502, and then the clamping jaw 406 is loosened by the clamping jaw cylinder 405, and then is rotated by 180° to the initial position towards the sheath entering position by the rotating cylinder 404, at this time the sheath is transported to the sheath positioning groove 502, and then the rotor feeding assembly is used to grab the rotor, the rotor feeding assembly is specifically a double-clamping manipulator 2, the rotor is inserted into the sheath on the sheath positioning groove 502 by the manipulator 2, finally, the receiving rod is driven to rise in the machine table 1 by the lifting cylinder 503 to align with the lower end of the rotor inserted into the sheath positioning groove 502, and then the pressing shaft 504 is driven to press down by the pressing cylinder 505 to align with the top end of the rotor inserted into the sheath positioning groove 502, so as to form the purpose of upper and lower alignment limiting, and then the rotor is completely pressed into the sheath by lifting or lowering to form a finished product, and the finished product of the rotor and the sheath is collectively referred to as "sleeve rotor 610" in the subsequent text;

[0060] Especially important,

[0061] After the sleeve rotor 610 is formed, the sleeve rotor 610 needs to be flanged and riveted, but the traditional flanging and riveting are separate processes, and need to be replaced from the flanging device to the processing device in the flanging and riveting processing, which is low in efficiency, in the present application, the flanging and riveting are combined to improve the processing efficiency, and the specific process steps are as follows:

[0062] Firstly, the robot 2 places the sleeve 610 on the pressing rod 604, which has a corresponding clamping structure, then the movable frame 602 is driven to move downward on the support frame 601 by the downward cylinder 603, when the movable frame 602 moves downward, the pressing rod 604 moves downward, when the pressing rod 604 drives the sleeve 610 to move downward, the sleeve 610 is aligned with the flanging head 608 on the flanging and riveting base 605 and enters the flanging head 608, after entering the flanging head 608, the rivet head 607 is conical and located in the middle of the flanging head 608 and extends out, the rivet head 607 just enters the middle of the sleeve 610, in this process, the pressing rod 604 above the sleeve 610 presses the sleeve 610, the flanging head 608, the rivet head 607 and the movable block 609 to move downward to the bottom of the support table, in this process, the switching block 606 plays a crucial role, as shown in Figure 6 the switching block 606 is driven by the external cylinder to insert into the innermost space of the support table, at this time, the movable block 609 is pushed on the upper side 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 to be flanged, in this process, because the rivet head 607 does not abut against the sleeve 610, there is still a certain space, only the purpose of flanging is achieved, then the purpose of riveting is achieved, the steps are as follows:

[0063] Referring to Figure 7 after flanging, the pressing rod 604 rises with the movable frame 602 and the downward cylinder 603, drives the sleeve 610 to separate from the flanging head 608 on the pressing rod 604, at the same time, the switching block 606 is extracted by the external cylinder, so that the left side of the switching block 606 is aligned with the left side of the movable block 609, then the pressing rod 604 drives the sleeve 610 to move downward again, after abutting against the flanging head 608, the flanging head 608 moves downward with the movable block 609, at this time, because the left side of the switching block 606 abuts against the left side of the switching block 606, because the left side of the switching block 606 is low, the sleeve 610 is lower than the height in the flanging process, at the lower height, the rivet head 607 is contacted, the pressing rod 604 gradually moves downward, so that the sleeve 610 is processed by the rivet head, to achieve the purpose of riveting.
