Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1 , 2As shown, a disassembly device for a small to medium-sized carbon brush motor includes a base device 2, a rack and pinion slider device 3, a three-jaw manipulator device 4, a ball screw drive device 6, and a gear 7. The ball screw drive device 6 is mounted on the base device 2, and the rack and pinion slider device 3 is mounted on the ball screw drive device 6. The base device 2 is provided with a gear 7 that meshes with the rack of the rack and pinion slider device 3. The three-jaw manipulator device 4 is mounted on the rack and pinion slider device 3. When the ball screw drive device 6 is working, under the guiding action of the meshing between the rack and pinion slider device 3 and the gear 7, the ball screw drive device 6 drives the rack and pinion slider device 3 to move up and down within the base device 2. When the three-jaw manipulator device 4 on the rack and pinion slider device 3 moves to a suitable position, the ball screw drive device 6 stops working, and then the stator housing of the small to medium-sized carbon brush motor is removed from the motor body by the three-jaw manipulator device 4.

[0023] In this invention, such as Figure 3-5 As shown, the base device 2 includes a support plate 201, a support base 202, and an insert plate 203. The support base 202 is installed on the top of the support plate 201. A U-shaped groove running through the front and back is opened on the top of the support base 202. Gears 7 are installed on the left and right side walls of the groove via rotating shafts 8. The rack and pinion slider device 3 is located in the groove, and its rack meshes with the corresponding gear 7. Slots of different heights are provided on the left and right sides of the support base 202. Insert plates 203 that can be inserted into the tooth grooves of the rack and pinion slider device 3 are inserted into the slots. The rack and pinion slider device 3 includes a rack 301, a positioning chuck 302, and a slider 306. A through hole running through the front and back walls is opened on the slider 306. The positioning chuck 302 is installed in the through hole. A three-jaw manipulator device 4 is installed on the positioning chuck 302. The rack 301 that meshes with the gear 7 is installed on the side wall of the slider 306. A U-shaped groove extending from front to back is provided at the top of the support base 202 to ensure that the entire rack and pinion slider device 3 can drive the three-jaw manipulator device 4 to move up and down. Meanwhile, slots of different heights are provided on the left and right sides of the support base 202. After the rack and pinion slider device 3 drives the three-jaw manipulator device 4 to the appropriate position, the insert plate 203 is inserted into the slot, so that the insert plate 203 engages with the tooth groove of the rack of the rack and pinion slider device 3. Simultaneously, a pair of opposing strip-shaped positioning holes 204 are provided on the left and right side walls of the support base 202. A positioning pin hole 304 matching the strip-shaped positioning hole is provided on the slider 306. A positioning pin is inserted into the strip-shaped positioning hole 204 and the positioning pin hole 304 and rests against the insert plate 203 to achieve height positioning of the rack and pinion slider device 3. This further fixes the position of the rack and pinion slider device 3, preventing the rack and pinion slider device 3 and the three-jaw manipulator device 4 from falling off the ball screw transmission device 6 due to excessive gravity during operation.

[0024] A handle 303 is provided on the top of the slider 306 to facilitate the extraction of the slider 306.

[0025] Preferably, the bottom of the support plate 201 is provided with a roller mechanism 1 with a self-locking function. The roller mechanism 1 facilitates the movement of the entire motor disassembly device. The roller mechanism 1 has a self-locking function and its structure is consistent with the existing self-locking mechanisms of strollers, etc. In this way, during the operation of the three-claw manipulator 4, the entire motor disassembly device can be prevented from shaking and affecting the disassembly of the motor.

[0026] like Figure 4 , 6As shown, the three-jaw manipulator device 4 includes a steering wheel 401, a steering wheel connector 402, a bottom connecting rod 403, a claw wrist connector 404, a base claw wrist 405, a wrist joint 406, a main gripper 407, and a support block 408. The base claw wrist 405 is fixedly mounted on the positioning chuck 302. Three guide holes are provided on the base claw wrist 405, and the three claw wrist connectors 404 are respectively located within the three guide holes on the base claw wrist 405. The front end of each claw wrist connector 404 is hinged via a connector. A wrist joint 406 is connected to the base claw wrist 405 via a connector. A main clamp 407 is fixedly installed on each wrist joint 406. The claw wrist connector 404 is hinged to the bottom connecting rod 403 via a connector. The bottom connecting rod 403 is connected to the steering wheel connector 402. The steering wheel 401 is installed on the steering wheel connector 402. A threaded section is provided on the bottom connecting rod 403. The threaded section is threadedly connected to the support block 408 fixed on the rack and pinion slider device 3. Since the bottom connecting rod 403 is threadedly connected to the support block 408 fixed on the rack and pinion slider device 3, rotating the steering wheel 401 forward and backward can drive the bottom connecting rod 403 to move back and forth. This, in turn, drives the claw wrist connector 404 to move back and forth. Because the two ends of the claw wrist connector 404 are respectively hinged to the bottom connecting rod 403 and the wrist joint 406, and the wrist joint 406 is hinged to the base claw wrist 405, the wrist joint 406 can rotate around its hinge during its forward and backward movement. This allows the three main clamps 407 to open and close. When it is necessary to grip the stator housing of the motor, first turn the steering wheel forward. 401. Open the three main clamps 407, then move the entire motor disassembly device so that the openings of the three main clamps 407 face the stator housing, and the gripping ends of the three main clamps 407 are located on the periphery of the stator housing. Reverse the steering wheel 401 to close the three main clamps 407 and grip the stator housing. During the process of closing the three main clamps 407 by reversing the steering wheel 401, the three main clamps 407 also exert a force on the stator housing away from the motor body. Thus, during the process of the three main clamps 407 gripping and clamping the stator housing, the stator housing can be removed from the faulty motor body by continuing to reverse the steering wheel 401.

[0027] like Figure 7As shown, a rotor clamping device 5 is fixedly installed on the base claw 405. The rotor clamping device 5 includes a chuck 501, a retaining spring 502, a rotating handle 503, clamping cutters 504, and a fixed plate 505. The fixed plate 505 is fixedly installed on the base claw 405. A notch is provided on the side wall of the fixed plate 505. The chuck 501 is provided with a rotating handle 503. The chuck 501 is fastened to the fixed plate 505, and the rotating handle 503 is located in the notch on the fixed plate 505. Three clamping cutters 504 are installed on the chuck 501 through the retaining spring 502. The three clamping cutters 504 are evenly installed along the circumferential direction. The positioning chuck 302, the base claw 405, the fixed plate 505, and the chuck 501 each have a through hole located on the same axis. The fixed plate 505 is provided with three guide holes corresponding to the base claw 405. During the disassembly of the stator housing, the chuck 501 is rotated clockwise by rotating the handle 503 to ensure that the three clamping tools 504 are open. After the motor shaft passes through the through hole in the middle of the positioning chuck 302, the base claw 405, the fixing plate 505, and the chuck 501, the handle 503 is released, and the three clamping tools 504 are restored to their original position under the action of the retaining spring 502 to fix the motor shaft, so as to prevent the motor shaft from moving with the stator housing during the disassembly process.

[0028] The working process of this invention:

[0029] According to the needs of the damaged or malfunctioning motor, under the meshing guidance of the rack 301 and gear 7, the rack slider device 3 is driven to move up and down in the base device 2 through the ball screw transmission device 6. When the three-jaw manipulator device 4 on the rack slider device 3 moves to the appropriate position, the ball screw transmission device 6 stops working. Then, the chuck 501 is rotated clockwise by the rotating handle 503 to ensure that the three clamping tools 504 open, so that the motor shaft passes through the through hole in the middle of the positioning chuck 302, the base claw 405, the fixed plate 505, and the chuck 501. Then, the rotating handle 503 is released, so that the three clamping tools 504 return to their original position under the action of the retaining spring 502, thereby fixing the motor shaft. Then, turn the steering wheel 401 forward to open the three main clamps 407. Then move the entire motor disassembly device so that the openings of the three main clamps 407 face the stator housing and the gripping ends of the three main clamps 407 are located on the periphery of the stator housing. Then, turn the steering wheel 401 backward to close the three main clamps 407 and grip the stator housing. During the process of closing the three main clamps 407 by turning the steering wheel 401 backward, the three main clamps 407 also exert a force on the stator housing away from the motor body. In this way, during the process of the three main clamps 407 gripping and clamping the stator housing, the stator housing can be removed from the faulty motor body by continuing to turn the steering wheel 401 backward.

[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
