[0002] A thin-wall motor refers to a motor with a housing thickness of less than 1 mm, belonging to a type of micro motor. When manufacturing the housing of a thin-wall motor, metal materials such as aluminum alloy and stainless steel are cut into blanks of appropriate size and shape, and then subjected to stretching deformation or bending to obtain the required outer shape and thickness. After the motor housing is formed, other components of the motor are installed inside the housing and sealed with seals, thus completing the assembly of the micro motor. However, due to factors such as the accuracy or deviation of cutting equipment during the processing of the metal housing of the thin-wall motor, burrs are likely to exist at the edge positions of the housing.

[0033] Embodiment 1: The present invention provides a burr removal device for a thin-walled motor housing, including a grinding machine mounting base 1; a mounting base positioning plate 101 is welded below the grinding machine mounting base 1, a motor guiding frame 102 is welded in front of the mounting base positioning plate 101, a longitudinally opened guiding frame longitudinal groove 103 with a "T" - shaped cross - section is formed in front of the motor guiding frame 102, a positioning lock opening 104 with a rectangular through - hole structure is penetrated through the mounting base positioning plate 101 from front to back, two support plate guiding holes 105 are longitudinally penetrated through the plate body of the grinding machine mounting base 1, and the support plate guiding holes 105 are used to guide the grinding support rod 602; a push - button type limit switch 201 is installed in front of the motor guiding frame 102 by screws; a grinding drive motor 2, the grinding drive motor 2 is electrically connected to the push - button type limit switch 201, the push - button type limit switch 201 is located above the grinding drive motor 2, a motor guide plate 202 is fixedly connected to the rear surface of the grinding drive motor 2, and the motor guide plate 202 is slidably connected in the guiding frame longitudinal groove 103, playing a guiding role, facilitating the vertical movement of the grinding drive motor 2 under the pulling of the positioning tension spring 402; an inner rotating shaft 3, the inner rotating shaft 3 is rotatably connected to the middle of the grinding machine mounting base 1 through a bearing, and a longitudinal through - hole is opened in the center of the inner rotating shaft 3; a rotating shaft sleeve 301 with a circular tube structure is fixedly connected above the inner rotating shaft 3, a sleeve wall groove 302 is opened on the tube wall of the rotating shaft sleeve 301, two positioning convex rings 303 are provided on the rotating shaft sleeve 301, and four pushing guide rods 304 are fixedly connected to the outer ring surface of each positioning convex ring 303; a lifting rotating rod 4, the lower end of the lifting rotating rod 4 is fixedly connected to the rotating shaft of the grinding drive motor 2 through a coupling, the lifting rotating rod 4 is movably inserted inside the rotating shaft sleeve 301 and slidably connected in the rotating shaft sleeve 301 and the inner rotating shaft 3, a positioning tension spring 402 is sleeved on the lifting rotating rod 4, the lower end of the positioning tension spring 402 is fixedly connected above the coupling at the butt - joint position of the grinding drive motor 2 and the lifting rotating rod 4, the upper end of the positioning tension spring 402 is fixedly connected to the lower end surface of the inner rotating shaft 3, eight hinged end blocks 401 are fixedly connected to the lifting rotating rod 4, and the hinged end blocks 401 are slidably connected in the sleeve wall groove 302, playing a guiding role; a positioning push block 5, a push block guiding opening 501 is formed on the inner surface of the positioning push block 5, the push block guiding opening 501 is sleeved on the pushing guide rod 304, and a rotating support rod 502 is hinged to the lower surface of the positioning push block 5, and the other end of the rotating support rod 502 is rotatably connected to the hinged end block 401;When the device is in a stopped state, the lifting and rotating rod 4 is in a lower position. The hinged end block 401 pulls the rotating support rod 502. The rotating support rod 502 has a relatively large slope. The positioning push block 5 is inserted on the pushing guide rod 304 and moves inward and closer, so that the outer surface of the positioning push block 5 does not contact the inner wall of the motor housing. The motor housing can be easily inserted outside the inner rotating shaft 3 and the positioning push block 5. When the device is in an operating state, the lifting and rotating rod 4 is pushed upward under the pulling action of the positioning tension spring 402, and the lifting and rotating rod 4 moves upward. The hinged end block 401 moves upward accordingly, applying a pushing force to the rotating support rod 502, making the slope of the rotating support rod 502 smaller. At the same time, the positioning push block 5 is pushed straight outward. The motor housing is firmly positioned by the close contact between the positioning push block 5 and the inner wall of the motor housing. The positioning push blocks 5 at eight places apply uniform pushing forces to the motor at different heights and in different directions inside the motor housing, making the positioning of the motor housing more stable, the pushing force uniform, and effectively reducing the probability of deformation of the motor housing caused by uneven stress on the motor housing.;;
[0034] Among them, the pushing and grinding frame 6 is movably connected to the grinding machine mounting seat 1. The mounting seat positioning plate 101 is perpendicular to the lower surface of the grinding machine mounting seat 1, and there are four round holes penetrating through the mounting seat positioning plate 101 from front to back; The mounting seat positioning plate 101 is fixed to the assembly table by screws passing through the four round holes, so that the mounting seat positioning plate 101 is fixed to the assembly table, and the grinding equipment is installed. The installation is convenient, the occupied space is small, and it does not interfere with the assembly work of the micro motor. The pushing and grinding frame 6 is of a ring structure, and there are two tightening tension springs 601 fixedly connected above the pushing and grinding frame 6. The upper ends of the tightening tension springs 601 are fixedly connected to the grinding machine mounting seat 1; The upper surface of the pushing and grinding frame 6 is fixedly connected with a grinding support rod 602, and the grinding support rod 602 is slidably connected in the support plate guide hole 105; The upper end of the grinding support rod 602 is fixedly connected with a grinding end block 603, and an arc-shaped V-shaped grinding groove 604 is opened in the middle of the upper surface of the grinding end block 603. The longitudinal section of the V-shaped grinding groove 604 is a "V" shape with an upward opening; When the motor housing is fixed, a downward pressure is applied to the grinding end block 603, causing the tightening tension spring 601 to contract, so that there is an appropriate extrusion force between the lower edge of the motor housing and the groove surface of the V-shaped grinding groove 604. Under the action of the extrusion force, the motor housing rotates and rubs against the V-shaped grinding groove 604, thereby grinding and removing the burrs on the edge of the motor housing.
[0035] Among them, a limit guide frame 203 is fixedly connected below the grinding drive motor 2. A limit pull rod 205 is slidably connected inside the limit guide frame 203. A limit top spring 204 is installed between the limit pull rod 205 and the limit guide frame 203. In the stopped state of the burr removal device, the rear end of the limit pull rod 205 is movably inserted into the positioning lock port 104. There is a gap between the grinding drive motor 2 and the button of the push-button type limit switch 201. The lifting rotating rod 4 is inside the inner rotating shaft 3 and in the lower position state, pulling the inner end of the rotating support rod 502 downward to control the positioning push block 5 to be in a contracted state. In this state, the motor housing can be easily sleeved outside the inner rotating shaft 3. In the operating state of the burr removal device, the limit pull rod 205 is located outside the positioning lock port 104, and the grinding drive motor 2 triggers the push-button type limit switch 201. When using the grinding device to grind the motor housing, pull the limit pull rod 205 outward to make the inner end of the limit pull rod 205 disengage from the positioning lock port 104, and then release the limit pull rod 205 or slowly push the limit pull rod 205 upward, so that the grinding drive motor 2 moves upward under the action of the positioning tension spring 402, pushing the lifting rotating rod 4 upward. During the upward movement of the lifting rotating rod 4, the height of the inner rotating shaft 3 remains unchanged, and the lifting rotating rod 4 slides upward inside the inner rotating shaft 3, causing the hinged end block 401 to rise, pushing the inner end of the rotating support rod 502 upward, making the slope of the rotating support rod 502 smaller, and pushing the positioning push block 5 to move outward. The eight positioning push blocks 5 slide outward synchronously on the push rod 304 to push against the inner wall of the motor housing, and position it through the friction force between the positioning push block 5 and the inner surface of the motor housing. At the same time, as the grinding drive motor 2 moves upward, the grinding drive motor 2 presses the button of the push-button type limit switch 201, thereby starting the grinding drive motor 2. The grinding drive motor 2 starts to drive the lifting rotating rod 4, the inner rotating shaft 3, the positioning push block 5, and the motor housing to rotate, so that the lower edge of the motor housing generates friction with the V-shaped grinding groove 604, thereby removing the burrs on the lower edge of the motor housing.
[0036] Embodiment 2: The present invention provides a burr removal device for a thin-walled motor housing. The V-shaped grinding groove 604 is provided with convex patterns on its groove surface. After the grinding end block 603 is made of carbon tool steel T12 and heat-treated, its surface is quenched, so that the V-shaped grinding groove 604 has high strength and slows down the wear speed of the grinding end block 603.
[0037] Specific usage and functions: In the present invention, first, the burr removal device is fixedly installed on the side or around the work station of the micro-motor assembly table through the cooperation of screws and the mounting base positioning plate 101 at a position convenient for the operator to operate. During the assembly of the micro-motor, if burrs are found at the lower edge of the thin-walled outer shell of the micro-motor, the thin-walled outer shell can be sleeved on the upper end of the inner rotating shaft 3, outside the positioning push block 5, and the motor outer shell is slightly pressed downward to make the lower edge of the motor outer shell closely fit with the V-shaped grinding groove 604. Then, the limit pull rod 205 is pulled forward to make the inner end of the limit pull rod 205 disengage from the positioning lock port 104. Then, the limit pull rod 205 is released, and the grinding drive motor 2 and the lifting rotating rod 4 move upward under the pulling force of the positioning spring 402. During the upward movement of the lifting rotating rod 4, the height of the inner rotating shaft 3 remains unchanged, and the lifting rotating rod 4 slides upward inside the inner rotating shaft 3, causing the articulated end block 401 to rise with the lifting rotating rod 4, pushing the inner end of the rotating support rod 502 upward, making the slope of the rotating support rod 502 smaller, and pushing the positioning push block 5 to slide outward synchronously on the pushing guide rod 304, so that the positioning push block 5 fits with the inner wall of the motor outer shell and pushes against the inner wall of the motor outer shell. The motor outer shell is positioned through the friction force between the positioning push block 5 and the inner surface of the motor outer shell. As the grinding drive motor 2 moves upward, the grinding drive motor 2 presses the button of the point-type limit switch 201, thereby starting the grinding drive motor 2. The grinding drive motor 2 starts to drive the lifting rotating rod 4, the inner rotating shaft 3, the positioning push block 5, and the motor outer shell to rotate, causing the lower edge of the motor outer shell to rub against the V-shaped grinding groove 604, thereby removing the burrs at the lower edge of the motor outer shell. After the motor outer shell is ground, the limit pull rod 205 is pushed downward, and the limit pull rod 205 is inserted into the positioning lock port 104 again under the action of the limit top spring 204. The grinding drive motor 2 moves downward, separating the point-type limit switch 201 from the grinding drive motor 2, and the grinding drive motor 2 is turned off, stopping the drive of the lifting rotating rod 4. Then, as the lifting rotating rod 4 moves downward, the articulated end block 401 pulls the inner end of the rotating support rod 502 downward, the slope of the rotating support rod 502 becomes smaller, and the positioning push block 5 is pulled inward, separating the positioning push block 5 from the inner wall of the motor outer shell, and the fixation of the motor outer shell can be released. The motor outer shell can be pulled upward to be removed, thus completing the burr grinding process of the motor outer shell.
