The lower portion of top cap 4 is provided with pressing plate 6, and pressing plate 6 is annular structure with notch, and pressing plate 6 is fixed between top cap 4 through four struts 5.

[0025] As shown in Figure 2 , 3 shows, and lower die 2 is fixedly provided in a stacked manner from top to bottom by first limiting plate 32, second limiting plate 33, third limiting plate 34 and base plate 35. A positioning groove 8 is formed in the center, and the shape of the positioning groove 8 is adapted to the shape of the motor 20. The positioning groove 8 penetrates the first limiting plate 32, the second limiting plate 33 and the third limiting plate 34. A limiting groove 9 is also formed in the positioning groove 8, and the limiting groove 9 accommodates the motor cover plate 21, which can prevent the motor 20 from rotating and shifting.

[0026] As shown in Figure 3 , 4 shows, and six pressing block movable grooves 18 are arranged around the positioning groove 8, and the positions of the six pressing block movable grooves 18 are all located directly below the pressing plate 6. The pressing block movable grooves 18 penetrate the first limiting plate 32, the second limiting plate 33 and the third limiting plate 34, and a pressing block 10 is arranged in each pressing block movable groove 18. The pressing block 10 can slide up and down in the pressing block movable groove 18, and the top surface of the pressing block 10 is higher than the top surface of the first limiting plate 32. The middle part of the pressing block 10 in the vertical direction is provided with an inclined pressing surface 13, which makes the overall width of the pressing block 10 wider at the top and narrower at the bottom.

[0027] As shown in Figure 4 , a punch movable groove 12 is also formed in the second limiting plate 33, and the punch movable groove 12 communicates with the pressing block movable groove 18. A punch 11 is arranged in the punch movable groove 12, and the punch 11 can slide back and forth in the punch movable groove 12. Figure 5As shown, the punch 11 consists of a slanted pressure block 14 and a guillotine cutter 16. The slanted pressure block 14 cooperates with the slanted pressure surface 13, so that when the pressure block 10 moves downward, it can push the punch 11 to move towards the motor 20. A spring 19 is also provided in the gap between the slanted pressure block 14 and the punch movable groove 12, and the spring 19 provides the punch 11 with elastic force away from the motor 20. A guide groove 15 is also provided on the punch movable groove 12. The shape of the guide groove 15 is adapted to the guillotine cutter 16, providing stable movement guidance for the guillotine cutter 16. The guide groove 15 communicates with the positioning groove 8, and the position of the communication opening corresponds to the position of the riveting point 23 of the motor 20. The cutter head 17 at the end of the guillotine cutter 16 is provided with a vertically inclined surface 36. The height of the inclined starting end of the inclined surface 36 is higher than the top surface height of the motor housing 22, so that the motor housing 22 is subjected to a stable pressing force from the cutter head 17 during the riveting process.

[0028] When riveting the motor housing 22, the die handle 3 is first installed on the pressure bar of the press, and the lower die 2 is installed on the worktable of the press. The pressure bar drives the upper die 1 to move closer to the lower die 2. During the process of the pressure plate 6 pressing down on the six pressure blocks 10, the inclined pressure surface 13 pushes the inclined pressure block 14 to compress the spring 19, and the six punches 11 move towards the motor 20 at the same time. The inclined surface 36 of the cutter head 17 first contacts the top edge of the motor housing 22, causing the motor housing 22 to turn inward from the top, gradually riveting the motor housing 22 to the riveting point 23 of the motor 20, thus fixing the motor housing 22 to the motor 20. After riveting is completed, the upper die 1 moves upward. When the upper die 1 releases the pressure on the pressure block 10, the punches 11 move away from the motor 20 under the action of the spring 19, driving the pressure block 10 to move upward, completing the reset.

[0029] like Figures 6-8 As shown, the lower mold 2 is also provided with a disassembly groove 26, which is fan-shaped and forms an open end on the lower mold 2. The disassembly groove 26 is provided through the first limiting plate 32, the second limiting plate 33, the third limiting plate 34 and the base plate 35. At the bottom of the positioning groove 8, the base plate 35 is provided with a through hole 30 that penetrates the base plate 35. A support rod 25 is fixed across the disassembly groove 26. A striking rod 24 that can rotate around the support rod 25 is provided on the support rod 25. One end of the striking rod 24 extends to the bottom of the through hole 30 and is provided with a fork 27 at this end. The fork 27 is semi-circular. A rotatable lifting seat 28 is provided between the forks 27 through a pin 31. The top of the lifting seat 28 is provided with a guide rod 29 that matches the shape of the through hole 30. The guide rod 29 is inserted into the through hole 30.

[0030] After riveting of the motor housing 22 is completed, the striking rod 24 is used as a lever, the supporting rod 25 is used as a fulcrum, the free end of the striking rod 24 is pressed downward, the striking rod 24 rotates around the supporting rod 25, the lifting seat 28 is driven by the fork head 27 to move upward, the guide rod 29 extends from the top of the through hole 30, and the motor 20 is lifted out of the positioning groove 8.

[0031] The bottom surface of the top cover 4 is fixedly provided with a pre-pressing column 7, the pre-pressing column 7 is telescopic, and a spring is arranged in the pre-pressing column 7 to provide telescopic force. The bottom surface of the pre-pressing column 7 is lower than the bottom surface of the pressing plate 6, and the pre-pressing column 7 can contact the top surface of the motor 20 in advance during downward movement of the upper die 1, so that the motor 20 is pre-pressed to prevent the motor 20 from floating up.

[0032] In the description of the present application, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inner", "outer", "back", "middle" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.
