Description

Technical Field

[0001] This invention belongs to the field of carbon brush processing technology, specifically relating to an automatic carbon brush grinding device. Background Technology

[0002] In the production and processing of carbon brushes, grinding is a crucial step. Its purpose is to treat the surface of the carbon brush to meet the flatness and smoothness requirements for use, so as to ensure that the carbon brush can work properly in equipment such as motors.

[0003] Currently, existing carbon brush equipment typically requires manual loading and grinding of the carbon brushes. After grinding, the brushes are removed from the equipment before the next brush is ground. This entirely manual method significantly impacts production efficiency. Manual loading and grinding is time-consuming, requiring this series of steps for each brush, making continuous production impossible. This inefficiency is particularly pronounced in large-scale carbon brush production, severely hindering production progress. Secondly, manual operation makes it difficult to guarantee consistent grinding precision. Due to differences in operator skill levels, operating habits, and physical condition, the position and angle of the carbon brushes may deviate, leading to inconsistent quality after grinding. Some brushes may be over-ground, while others may be under-ground, failing to meet uniform standards and affecting product yield. Furthermore, the grinding process generates a large amount of dust and debris. Operators working in such an environment for extended periods are prone to inhaling dust, which can harm their health. At the same time, when manually placing and removing carbon brushes, the hands may come into contact with the grinding parts, posing a risk of being scratched. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic carbon brush grinding device, which can realize automatic continuous feeding of carbon brushes and complete the processes of carbon brush transfer, positioning and rotation, grinding, and unloading between various processes.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: an automatic carbon brush grinding device, including a cabinet, on which a feeding component, a clamping and moving component, a clamping and rotating component, a grinding component, and a discharge conveyor belt are installed;

[0007] The clamping and moving component has one end located at the end of the feeding conveyor belt and the other end located at the beginning of the discharging conveyor belt. The clamping and moving component includes a pneumatic gripper, which can move laterally and vertically.

[0008] The clamping and rotating assembly includes two clamping plates that can move relative to each other and can rotate.

[0009] The grinding assembly includes a grinding base and a grinding head, which can move horizontally and vertically.

[0010] Furthermore, both the feeding conveyor belt and the discharging conveyor belt include a conveyor belt, a drive roller, and a motor. One of the drive rollers of the feeding conveyor belt is equipped with a main bevel gear at its end, and the main bevel gear meshes with the driven bevel gear.

[0011] Furthermore, a rectangular discharge port is provided in the chute. The size of the discharge port is slightly larger than the size of the carbon brush. The discharge port is located directly above the feed conveyor belt, and the carbon brush can fall onto the conveyor belt of the feed conveyor belt through the discharge port.

[0012] Furthermore, the clamping and moving assembly includes a bracket, a fixed plate mounted on the top of the bracket, a horizontal slide rail mounted on the fixed plate, a horizontal slider slidably mounted on the horizontal slide rail, a transverse plate mounted on the horizontal slider, pulleys rotatably mounted at both ends of the fixed plate, a belt chain mounted between the two pulleys, a first motor connected to the pulleys, a connecting block fixed on the transverse plate, and the transverse plate fixedly connected to the belt chain through the connecting block.

[0013] Furthermore, an electric cylinder is installed on the horizontal moving plate, a vertical moving plate is connected to the output shaft of the electric cylinder, a vertical slide rail is installed on the horizontal moving plate, a vertical slider is slidably installed on the vertical slide rail, the vertical slider is fixedly connected to the vertical moving plate, and a pneumatic gripper is installed on the vertical moving plate.

[0014] Furthermore, the clamping and rotating assembly includes a base, slide rails are installed on both sides of the base, translation plates are installed on the slide rails, a slide block is installed below the translation plate, the slide block is slidably installed on the slide rails, and electric actuators are installed at both ends of the base, with the output end of the electric actuator fixed to the translation plate.

[0015] Furthermore, a second motor is fixedly installed on the translation plate, with the output ends of the second motor positioned opposite each other, and the clamping plate is connected to the output shaft of the second motor.

[0016] Furthermore, the grinding assembly includes a base, with horizontal guide rails mounted on both sides of the base, horizontal guide blocks slidably mounted on the horizontal guide rails, a sliding plate mounted between the two horizontal guide blocks, a first lead screw mounted on the horizontal guide rails, a movable block slidably mounted on the first lead screw, and the movable block mounted below the sliding plate.

[0017] Furthermore, the skateboard has side plates installed on both sides, a top plate installed on the top of the two side plates, vertical guide rails installed vertically on the side plates, vertical guide blocks slidably installed on the vertical guide rails, a second lead screw rotatably installed on the top plate, a grinding seat slidably installed on the second lead screw, the grinding seat is fixedly connected to the vertical guide block, a grinding head is installed on the grinding seat, a grinding motor is connected to the rear end of the grinding head, and a fourth motor is connected to the top of the second lead screw.

[0018] Compared with the prior art, the beneficial effects of this invention are as follows: Several carbon brushes are placed in the feeding trough of the feeding assembly. When the motor drives the feeding conveyor belt, the meshing relationship between the main bevel gear and the driven bevel gear drives the Z-shaped rocker arm to rotate, thereby driving the pusher plate to indirectly push the carbon brushes. The carbon brushes fall from the discharge port onto the feeding conveyor belt below and are finally transported to its end by the feeding conveyor belt. By controlling the pneumatic gripper in the clamping moving assembly to move to the end of the feeding conveyor belt, the carbon brushes are clamped and moved between the two clamping plates in the clamping rotating assembly. By controlling the electric push rod to drive the translation plate to move towards the middle, the carbon brushes are clamped between the two clamping plates. Subsequently, the grinding head can be controlled to move onto the carbon brushes to perform a grinding operation. During the grinding process, the second motor can be controlled to drive the clamping plates and carbon brushes to rotate, grinding different surfaces of them. After the carbon brushes are ground, the clamping moving assembly can be used to clamp the carbon brushes and move them to the discharge conveyor belt for transfer. The grinding of the carbon brushes is completed.

[0019] This invention's device achieves continuous carbon brush feeding through a feeding assembly, replacing manual feeding and significantly improving production efficiency to meet the needs of large-scale continuous production. Simultaneously, a clamping and moving assembly moves the carbon brush to a clamping and rotating assembly, where it is ground by a grinding assembly. The fully automated operation reduces manual intervention, avoids operator contact with dust and grinding components, lowers health and safety risks, saves labor costs, and improves production safety and economy.

[0029] See Figure 1 As shown, the present invention provides an automatic carbon brush grinding device, including a cabinet 101. The cabinet 101 is a rectangular frame structure composed of square tubes and sheet metal, and four casters are installed at the bottom of the cabinet 101. A feeding assembly is installed on one side of the cabinet 101, including a feeding conveyor belt 102, and an output conveyor belt 103 is installed on the other side of the cabinet 101. The feeding conveyor belt 102 and the output conveyor belt 103 are installed along the width direction of the cabinet 101. Both the feeding conveyor belt 102 and the output conveyor belt 103 include a conveyor belt, a drive roller, and a motor. The surface of the conveyor belts of both the feeding conveyor belt 102 and the output conveyor belt 103 has raised ribs 104, and baffles 105 are installed on both sides and at the ends of the feeding conveyor belt 102 and the output conveyor belt 103. During the transportation of carbon brushes, the baffles 105 can limit the movement of the carbon brushes. A clamping and moving assembly is installed at the same end of the feed conveyor belt 102 and the discharge conveyor belt 103, and the clamping and moving assembly is installed along the length of the cabinet 101. A grinding assembly and a clamping and rotating assembly are installed in the middle of the feed conveyor belt 102 and the discharge conveyor belt 103, with the grinding assembly located directly in front of the clamping and rotating assembly.

[0030] See Figure 2-3 As shown, the aforementioned feeding assembly includes a base plate 201, which is fixedly installed above the feeding conveyor belt 102. A rectangular feeding trough 202 is provided on one side of the base plate 201. A rectangular discharge port is provided on one side of the feeding trough 202, and several carbon brushes to be ground are placed inside the feeding trough 202. A pusher plate 203 is installed inside the feeding trough 202, the size of which matches the feeding trough 202, and the pusher plate 203 can move horizontally along the feeding trough 202. A pusher rod 204 is installed on one side of the pusher plate 203. A cylindrical hole is formed on the side wall of the feeding trough 202, located on the opposite side of the discharge port. One end of the push rod 204 extends out of the cylindrical hole, and a push block 205 is installed on the other side of the push rod 204. Return springs 206 are fixed on both sides of the feeding trough 202. One end of the return spring 206 is fixed to the side wall of the feeding trough 202, and the other end is fixed to the side of the push block 205. The return spring 206 possesses elastic potential energy, which can push the push block 205 towards the discharge port.

[0031] A chute 207 is provided on one side of the feeding chute 202, and the chute 207 communicates with the feeding chute 202. The discharge port is located at the junction of the chute 207 and the feeding chute 202. A pusher plate 208 is slidably installed in the chute 207, and the pusher plate 208 matches the chute 207. A straight groove 209 is vertically provided on one side of the pusher plate 208. A Z-shaped rocker arm 212 is rotatably installed on the base plate 201, and the Z-shaped rocker arm 212 is located on one side of the chute 207. One end of the Z-shaped rocker arm 212 is engaged in the straight groove 209. The other end of the Z-shaped rocker arm 212 passes through the base plate 201, and a driven bevel gear 210 is installed below it. A main bevel gear 211 is installed at the end of one of the drive rollers of the feed conveyor belt 102, and the main bevel gear 211 meshes with the driven bevel gear 210. A rectangular discharge port is provided in the chute 207. The size of the discharge port is slightly larger than the size of the carbon brush. The discharge port is located directly above the feed conveyor belt 102. The carbon brush can fall into the conveyor belt of the feed conveyor belt 102 through the discharge port.

[0032] Several carbon brushes are placed in the feeding trough 202. The pusher plate 203, driven by the pusher rod 204, pusher block 205, and return spring 206, pushes the carbon brushes towards the discharge port. When the motor drives the feeding conveyor belt 102, the main bevel gear 211 at the end of its transmission roller drives the bevel gear 210 and Z-shaped rocker arm 212 to rotate. When the Z-shaped rocker arm 212 rotates, one end moves back and forth within the straight groove 209, driving the pusher plate 208 to slide back and forth along the slide groove 207. When the pusher plate 208 slides to the discharge port of the feeding trough 202, it obstructs the carbon brushes in the feeding trough 202. When the pusher plate 208 slides to the side of the discharge port and is in a retracted state, it no longer obstructs the discharge port. The pusher plate 203, under the action of the return spring 206, pushes forward, pushing the carbon brushes in the feeding trough 202 into the slide groove 207. At this time, as the pusher plate 208 slides in the reverse direction, it pushes the carbon brush along the chute 207 to the discharge port. The carbon brush falls from the discharge port onto the feed conveyor belt 102 below, and is finally transported to its end by the feed conveyor belt 102. This cycle repeats, realizing continuous automatic feeding of carbon brushes.

[0033] After the feeding process is completed, the carbon brush at the end of the feeding conveyor belt 102 will be clamped by the clamping moving component and transferred to the clamping rotating component, where the clamping rotating component will perform positioning and clamping operations on the carbon brush.

[0034] See Figure 4As shown, the clamping and moving assembly includes two brackets 301 fixedly mounted on the surface of the cabinet 101. A fixing plate 302 is horizontally fixedly mounted on the top of the two brackets 301. One end of the fixing plate 302 is located at the end of the feeding conveyor belt 102, and the other end is located at the initial end of the discharging conveyor belt 103. A horizontal slide rail 303 is horizontally fixedly mounted along the length of the fixing plate 302. A horizontal slider 304 is slidably mounted on the horizontal slide rail 303. A horizontal moving plate 305 is fixedly mounted on the horizontal slider 304. An electric cylinder 308 is fixedly mounted on the horizontal moving plate 305, with its output shaft pointing vertically downwards. A vertical moving plate 306 is fixedly connected to the output shaft of the electric cylinder 308 and can move vertically. A vertical slide rail is vertically fixedly mounted on the horizontal moving plate 305, with a vertical slider slidably mounted on the vertical slide rail and fixedly connected to the vertical moving plate 306. A pneumatic gripper 307 is fixedly mounted on the vertical moving plate 306. Pulleys 309 are rotatably mounted at both ends of the fixed plate 302, and a belt chain 310 is installed between the two pulleys 309. A first motor 311 is connected to one of the pulleys 309. A connecting block is fixed behind the translation plate 404, and the transverse plate 305 is fixedly connected to the belt chain 310 through the connecting block. When the first motor 311 drives the belt chain 310 to rotate, it can drive the transverse plate 305 to move horizontally along the transverse slide rail 303, thereby driving the pneumatic gripper 307 to move horizontally along the transverse slide rail 303 to clamp the carbon brush at the end of the feed conveyor belt 102 and transfer it to the clamping rotating assembly.

[0035] See Figure 5 As shown, the clamping rotation assembly is located below the clamping movement assembly. The clamping rotation assembly includes a base 401, with slide rails 402 fixedly mounted on both sides of the base 401. Two translation plates 404 are installed between the two slide rails 402, and two slide blocks 403 are fixedly mounted below each translation plate 404, slidably mounted on the slide rails 402. A second motor 405 is fixedly mounted on each translation plate 404, with the output ends of the second motors 405 on the two translation plates 404 facing each other. A clamping plate 406 is connected to the output shaft of the second motor 405, allowing the second motor 405 to drive the clamping plate 406 to rotate. Stabilizing plates are provided at both ends of the base 401, with electric actuators 407 fixedly mounted on the stabilizing plates. The output ends of the electric actuators 407 are fixed to the translation plates 404. By using the electric actuators 407 at both ends to move the translation plates 404 closer together, the carbon brush can be clamped between the two clamping plates 406. After the carbon brush is positioned, it can be ground using the grinding component.

[0036] See Figure 6As shown, the grinding assembly includes a base 501, with horizontal guide rails 502 fixedly mounted on both sides of the base 501. Horizontal guide blocks 503 are slidably mounted on the horizontal guide rails 502, and a sliding plate 504 is fixedly mounted between the two horizontal guide blocks 503. A first lead screw 505 is mounted in the middle of the horizontal guide rails 502, and a moving block is slidably mounted on the first lead screw 505. The moving block is fixedly mounted below the sliding plate 504. When the third motor 506 drives the first lead screw to rotate, it can drive the sliding plate 504 to move horizontally.

[0037] Side plates 507 are vertically fixedly installed on both sides of the slide plate 504, and a top plate 508 is fixedly installed on the top of the two side plates 507. A vertical guide rail 509 is vertically fixedly installed on each side plate 507, and a vertical guide block 514 is slidably installed on the vertical guide rail 509. A second lead screw 510 is vertically and downwardly rotatably installed in the middle of the top plate 508, and a grinding seat 511 is slidably installed on the second lead screw 510. The grinding seat 511 is fixedly installed between the two vertical guide blocks 514. A grinding head 512 is installed on the grinding seat 511, and a grinding motor is connected to the rear end of the grinding head 512. A fourth motor 513 is connected to the top of the second lead screw 510. When the fourth motor 513 drives the second lead screw 510 to rotate, it can drive the grinding seat 511 and the grinding head 512 to move vertically.

[0038] Example: Several carbon brushes are placed in the feeding trough 202 of the feeding assembly. When the motor drives the feeding conveyor belt 102, the meshing relationship between the main bevel gear 211 and the driven bevel gear 210 drives the Z-shaped rocker arm 212 to rotate, thereby driving the pusher plate 208 to indirectly push the carbon brushes. The carbon brushes fall from the feeding port onto the feeding conveyor belt 102 below, and are finally transported to its end by the feeding conveyor belt 102. By controlling the pneumatic gripper 307 in the clamping and moving assembly to move to the end of the feeding conveyor belt 102, the carbon brushes are clamped and moved between the two clamping plates 406 in the clamping and rotating assembly. By controlling the electric push rod 407 to drive the translation plate 404 to move towards the middle, the carbon brushes are clamped between the two clamping plates 406. Subsequently, the grinding head 512 can be controlled to move onto the carbon brushes to perform a grinding operation. During the grinding process, the second motor 405 can be controlled to drive the clamping plates 406 and the carbon brushes to rotate, grinding different surfaces of them. After the carbon brush is ground, it can be clamped by the clamping and moving assembly and moved onto the discharge conveyor belt 103 for transfer. This completes the grinding process of the carbon brush.
