[0002] The motor output shaft is an important part of the motor, and its surface quality and precision have a significant impact on the performance and service life of the motor. In the production process of the motor output shaft, grinding is a key process to remove burrs and flash on the shaft surface and improve the surface finish and straightness.

[0003] At present, the traditional method of grinding the motor output shaft mainly relies on manual operation. Workers use handheld grinding tools to grind the motor output shaft. However, the manual grinding process often takes a lot of time and manpower due to the limited speed and accuracy of manual operation, which leads to extended production cycles and increased costs. Moreover, the quality of manual grinding is unstable. It is difficult to grind the output shaft evenly during the grinding process with an abrasive belt, resulting in uneven grinding of the output shaft surface, which affects the service life of the output shaft in the later stage.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] One of the purposes of the present invention is to provide a grinding device for producing a dual-axis motor output shaft, such as Figure 1-7 As shown, it includes a body 100, a triangular chuck 101 is provided at the end of the body 100, a movable ejector 102 is provided on the opposite surface of the triangular chuck 101, a support seat 103 is provided on the surface of the body 100, and symmetrical sensors 104 are provided on both sides of the surface of the support seat 103, a movable frame 200 is provided on the surface of the body 100, a support block 201 is provided at the bottom of the movable frame 200, a cylinder 202 is provided at the bottom of the support block 201, a movable block 203 is provided at the end of the cylinder 202, a buffer component is provided between the cylinder 202 and the movable block 203, a friction roller 207 is provided at the end of the movable block 203, a transmission roller 208 is provided at the end of the support block 201, and the friction roller 209 is provided at the end of the movable block 203. A friction belt 210 is provided between the shaft 207 and the transmission roller 208, a gear rod 209 is provided at the end of the transmission roller 208, a grinding assembly 400 is provided at the end of the gear rod 209, and the grinding assembly 400 is used to move and grind the output shaft clamped at the end of the triangular chuck 101. A limit assembly 300 is provided on the surface of the support seat 103, and the limit assembly 300 is used to support the output shaft. At the same time, when the grinding assembly 400 passes through the limit assembly 300, the limit assembly 300 automatically moves away from both sides of the output shaft. A dust collection assembly 500 is provided on the inner wall of the movable frame 200, and the dust collection assembly 500 is used to absorb and collect dust generated during the grinding process.

[0037] Considering that during the grinding process of the output shaft, when the output shaft is long, when the end of the output shaft is clamped and fixed by the triangular chuck 101, the surface of the output shaft is prone to jumping, which will cause an uneven surface during the grinding process, and the required smoothness and precision cannot be achieved, resulting in an increased wear rate of the output shaft and affecting its service life. Therefore, the limit assembly 300 includes a servo motor 301 arranged on one side of the support seat 103, and the output shaft of the servo motor 301 is provided with two groups of clamping and fixing assemblies, and belt shafts are provided at the ends between the clamping and fixing, and a transmission belt 307 is provided between the belt shafts. The clamping and fixing assembly includes a screw rod 302 arranged on the output shaft of the servo motor 301, and the thread on the surface of the screw rod 302 is symmetrical, and the thread on the surface of the screw rod 302 is connected to a movable base 303, and the movable base 303 is symmetrical, and a support rod is provided on the surface of the movable base 303, and a swing arm 304 is provided on the surface of the support rod for rotation, and a roller rod 305 is provided on the inner wall of the swing arm 304 to support An elastic member 306 is provided on the rod surface, wherein the elastic member 306 can be replaced by a torsion spring. The two ends of the elastic member 306 are respectively connected to the side wall of the swing arm 304 and the inner wall of the movable base 303. In a natural state, the swing arm 304 is perpendicular to the horizontal plane due to the force of the elastic member 306. When the output shaft is installed and fixed, the output shaft at the end of the servo motor 301 drives the screw rod 302 to rotate, so that the movable base 303 provided on the surface of the screw rod 302 moves relatively. During the movement of the movable base 303, the swing arm 304 is driven to move, so that the roller rod 305 at the end of the swing arm 304 squeezes and limits the two sides of the output shaft. Since the quadrant of the roller rod 305 is parallel to the quadrant of the output shaft, the roller rod 305 is always kept in close contact with the side wall of the output shaft due to the force of the elastic member 306 during the rotation of the output shaft, thereby limiting the output shaft during grinding, avoiding the output shaft from jumping due to loose clamping, and improving the service life of the output shaft.

[0038] In order to limit the top of the output shaft and keep the output shaft rotating stably, the piston rod at the end of the cylinder 202 drives the moving block 203 to move above the output shaft, so that the friction roller 207 arranged at the end of the moving block 203 is pressed against the top of the output shaft for rolling. According to the required height of the friction roller 207 and the top of the output shaft, the required length of the friction belt 210 is adjusted, so that the friction belt 210 is always kept at the tension required for the friction roller 207 to roll on the top of the output shaft for limiting, thereby improving the stability of the output shaft during rotation. In order to avoid the output shaft from jumping during rotation, resulting in deformation of the piston rod at the end of the cylinder 202 and affecting normal use, the buffer assembly includes a The cylinder 202 has a cylinder barrel 204 at the end of the piston rod, and a sliding column 205 is slidingly provided on the inner wall of the cylinder barrel 204. The end of the sliding column 205 is connected to the top of the moving block 203. A return spring 206 is provided between the cylinder barrel 204 and the sliding column 205. When the friction roller 207 limits the top of the rotating output shaft, when the output shaft jumps, the bottom of the friction roller 207 is subjected to thrust, so that the moving block 203 drives the sliding column 205 to slide along the inner wall of the cylinder barrel 204 in the vertical direction, so that the return spring 206 is squeezed. When the output shaft stops rotating, the sliding column 205 is subjected to the restoring force of the return spring 206 to drive the moving block 203 to move downward, so that the friction roller 207 provided at the end of the moving block 203 continues to limit the top of the output shaft.

[0039] The movable frame 200 is arranged on the surface of the rotating screw rod. When the rotating screw rod rotates, the movable frame 200 is driven to reciprocate in the horizontal direction. When the movable frame 200 moves, the sand belt 405 is driven to move horizontally to grind the rotating output shaft surface. At the same time, the friction roller 207 moves on the output shaft surface. The friction roller 207 and the output shaft surface generate friction and rotate. The transmission roller 208 is driven to rotate through the friction belt 210, so that the gear rod 209 provided at the end of the transmission roller 208 rotates. During the rotation process, the gear rod 209 drives the driven gear 407 to mesh and rotate, so that the driven gear 407 drives the extension rod to rotate, so that the collecting roller 406 rotates on the inner wall of the second fixed frame 402, and the collecting roller 406 collects the sand wound on the surface of the clockwork spring 404. The belt 405 is stretched, and the grinding area of ​​the surface of the sanding belt 405 is increased during the stretching process, thereby avoiding continuous grinding at the position where the surface of the sanding belt 405 and the output shaft are in contact, resulting in a reduction in the service life of the sanding belt 405. During the movement of the grinding assembly 400 driven by the mobile frame 200, when it moves above the support seat 103, the sensor 104 identifies the grinding assembly 400. At this time, the output shaft of the servo motor 301 drives the screw rod 302 to rotate, so that the limit assembly 300 on the side close to the mobile frame 200 is away from the output shaft surface. At this time, the limit assembly 300 on the side away from the mobile frame 200 is in contact with the output shaft surface for clamping and limiting, thereby ensuring that the grinding assembly 400 is unobstructed during the mobile grinding process, thereby improving the grinding efficiency.

[0040] In order to facilitate the rapid grinding of the output shaft surface and improve the grinding efficiency, the grinding assembly 400 includes a first fixed frame 401 and a second fixed frame 402 arranged at the bottom of the mobile frame 200, a collecting roller 406 is rotatably provided on the inner wall of the second fixed frame 402, a fixed roller 403 is provided on the inner wall of the first fixed frame 401, a spring spring 404 is provided on the surface of the fixed roller 403, an abrasive belt 405 is wound around the end of the spring spring 404, a free end of the abrasive belt 405 is fixed on the surface of the collecting roller 406, an extension rod is provided at the end of the collecting roller 406, the extension rod passes through the second fixed frame 402 and a driven gear 407 is provided at the end, the gear ratio of the driven gear 407 to the gear rod 209 is 5:1, and when the gear rod 209 rotates, it drives the driven gear 407 to mesh and rotate;

[0041] Taking into account that a lot of dust is generated during the grinding process, when the operator inhales the dust into the body, it will cause physical discomfort. Therefore, the dust collection component 500 includes a rotating motor 501 arranged on the side wall of the movable frame 200, the output shaft of the rotating motor 501 passes through the movable frame 200 and is provided with a fan blade 502 at the end, a cover tube 503 is provided outside the fan blade 502, an air suction port 506 is provided at the end of the cover tube 503, a dustproof plate 504 is provided inside the cover tube 503, and a filter screen 505 is provided at the end of the cover tube 503. The fan blade 502 is driven to rotate by the rotating motor 501, and the fan blade 502 blows out the air inside the cover tube 503, thereby generating a negative pressure inside the cover tube 503, so that air enters through the air suction port 506, and dust is adsorbed while the air enters, so that the dust enters the filter screen 505, thereby preventing the operator from inhaling and ensuring the personal safety of the operator.

[0042] When in use, the output shaft is clamped and fixed on the surface of the triangular chuck 101, the end of the output shaft is fixed by moving the ejector pin 102, and the output shaft at the end of the servo motor 301 drives the screw rod 302 to rotate, so that the movable base 303 provided on the surface of the screw rod 302 moves relatively, and the swing arm 304 is driven to move during the movement of the movable base 303, so that the roller rod 305 at the end of the swing arm 304 squeezes and limits the two sides of the output shaft. Since the quadrant of the roller rod 305 is parallel to the quadrant of the output shaft, the roller rod 305 is always kept in close contact with the side wall of the output shaft by the force of the elastic member 306 during the rotation of the output shaft, so as to limit the output shaft during grinding, and avoid the output shaft from jumping due to loose clamping, which leads to uneven grinding. The service life of the output shaft is improved. In the process of the mobile frame 200 driving the grinding assembly 400 to move, when it moves above the support seat 103, the sensor 104 identifies the grinding assembly 400. At this time, the output shaft of the servo motor 301 drives the screw rod 302 to rotate, so that the screw rod 302 close to the side of the mobile frame 200 rotates, so that the moving base 303 provided on the surface of the screw rod 302 moves away from the surface of the output shaft, so that the swing arm 304 provided on the surface of the moving base 303 drives the roller rod 305 away from the output shaft surface. At this time, the limiting assembly 300 away from the side of the mobile frame 200 is attached to the surface of the output shaft for clamping and limiting, thereby ensuring that the grinding assembly 400 is unobstructed during the mobile grinding process, thereby improving the grinding efficiency. When the mobile frame 200 moves, it drives the sanding belt 4 05 moves horizontally to grind the rotating output shaft surface. At the same time, the friction roller 207 moves on the output shaft surface. The friction roller 207 and the output shaft surface generate friction and rotate. The friction belt 210 drives the transmission roller 208 to rotate, so that the gear rod 209 provided at the end of the transmission roller 208 rotates. The gear rod 209 drives the driven gear 407 to mesh and rotate during the rotation process, so that the driven gear 407 drives the extension rod to rotate and the collecting roller 406 rotates on the inner wall of the second fixed frame 402. The collecting roller 406 stretches the sand belt 405 wound on the surface of the clockwork spring 404. During the stretching process, the surface of the sand belt 405 is always in contact with the surface of the output shaft and the grinding area with the output shaft is increased, thereby avoiding the surface of the sand belt 405 and the output shaft. The shaft-fitting position is continuously polished, which reduces the service life of the sanding belt 405. When the sanding area of ​​the sanding belt 405 is damaged, the damaged area is cut and the free end of the new sanding belt 405 is fixed to the end of the collecting roller 406 to improve the polishing efficiency. When the mobile frame 200 drives the polishing assembly 400 to move, when it moves to the top of the support seat 103, the sensor 104 identifies the polishing assembly 400. At this time, the output shaft of the servo motor 301 drives the screw rod 302 to rotate, so that the limit assembly 300 on the side close to the mobile frame 200 is away from the output shaft surface. At this time, the limit assembly 300 on the side away from the mobile frame 200 fits the output shaft surface for clamping and limiting, thereby ensuring that the polishing assembly 400 is unobstructed during the mobile polishing process.Always keep the limit on the middle of the output shaft to avoid output shaft jumping and improve grinding efficiency.

[0043] A second object of the present invention is to provide a method for grinding a dual-axis motor output shaft for production, comprising any one of the dual-axis motor output shaft grinding devices for production, comprising the following steps:

[0044] S1, clamp and fix the output shaft on the surface of the triangular chuck 101, and move the ejector pin 102 to fix the end of the output shaft;

[0045] S2. The limiting assembly 300 is used to limit the two sides of the center of the output shaft, so that the limiting assembly 300 always keeps in close contact with the side wall of the rotating output shaft, thereby improving the stability of the output shaft during the grinding process;

[0046] S3. The grinding assembly 400 is driven to move horizontally by the movable frame 200 so that the grinding assembly 400 fits the surface of the output shaft to grind it. When the gear rod 209 rotates, it drives the grinding assembly 400 to mesh and rotate, thereby increasing the grinding area of ​​the surface of the grinding assembly 400, thereby avoiding continuous grinding at the position where the surface of the grinding assembly 400 fits the output shaft, thereby increasing the service life of the grinding assembly 400.
