[0009] In a preferred embodiment of the robot-assisted automated grinding device for automobile wheel hubs according to the present invention, a threaded block is fixedly connected to the bottom of the electric push rod, and the threaded block is slidably connected to the top of the worktable.

[0010] In a preferred embodiment of the robot-assisted automated grinding device for automobile wheel hubs according to the present invention, the worktable surface is provided with multiple mounting slots at equal intervals, and a threaded rod is rotatably connected to the inner wall of the mounting slot, with the surface of the threaded rod being threadedly connected to the inner wall of the threaded block.

[0011] In a preferred embodiment of the robot-assisted automated grinding device for automobile wheel hubs according to the present invention, a limiting groove is formed on the inner wall of the mounting groove, and the limiting groove is slidably connected to the threaded block.

[0012] As a preferred embodiment of the robot-assisted automated grinding device for automobile wheel hubs according to the present invention, the adsorption mechanism includes a plurality of third connecting tubes arranged at equal intervals, the two ends of the third connecting tubes being fixedly connected to adjacent moving blocks, and a plurality of vacuum suction cups being fixedly connected to one side of the third connecting tubes, the plurality of vacuum suction cups being in contact with the inner wall of the wheel hub.

[0013] In a preferred embodiment of the robot-assisted automated grinding device for automobile wheel hubs according to the present invention, a second connecting pipe is fixedly connected to the top of the adjacent third connecting pipe, a first connecting pipe is fixedly connected to the top of the second connecting pipe, and the first connecting pipe is equidistantly arranged above the third connecting pipe.

[0014] As a preferred embodiment of the robot-assisted automated grinding device for automobile wheel hubs of the present invention, an air extraction pipe is fixedly connected to the top of the first connecting pipe, a vacuum pump is fixedly connected to one end of the air extraction pipe, and a positioning plate is fixedly connected to the bottom of the vacuum pump.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When a wheel hub needs to be processed, the operator can place the wheel hub on top of the placement tray. Then, to fix the wheel hub, the operator can start the second motor. The second motor drives the bevel gear to rotate. As the bevel gear rotates, it drives the meshing gear ring to rotate along the inner wall of the housing. As the gear ring continues to rotate along the inner wall of the housing, because the top of the gear ring is threaded to the bottom of the moving block, the moving block gradually moves away from the housing axis along the surface of the housing. Simultaneously, as the moving block moves away from the housing axis, it drives the positioning sleeve, movable rod, and clamping plate to gradually approach the inner wall of the wheel hub until one side of the clamping plate is completely in contact with the inner wall of the wheel hub to be ground, facilitating effective fixing of the wheel hub. The clamping plate at the end of the movable rod is connected to the first... The combined force of the spring and the second spring, tightly adhering to the inner wall of the wheel hub, effectively clamps the hub while allowing for adaptive adjustments based on its size. This prevents damage due to excessive clamping force. The design ensures effective wheel hub clamping, guaranteeing that subsequent grinding operations follow a predetermined trajectory and force. This guarantees high standards for the flatness, roundness, and roughness of the processed wheel hub surface. Furthermore, the adjustable clamping mechanism can be tailored to the specific dimensions of the wheel hub, ensuring that wheels from both small and large vehicles are accurately and securely fixed to the grinding device. This not only solves the compatibility issue of various wheel hub specifications but also improves production efficiency and product quality, meeting the requirements of modern automated production lines for high efficiency, precision, and flexibility.

[0016] 2. The placement plate of this invention is used to support the wheel hub to be polished. When the first motor is started, it drives the placement plate and the wheel hub on it to rotate together through the rotating rod. In this way, when the robot or polishing tool polishes the wheel hub along a specific trajectory, the rotation of the wheel hub itself can ensure that all sides can be processed evenly and comprehensively, which greatly improves the polishing quality and efficiency.

[0017] 3. This invention uses multiple electric push rods equidistantly positioned on the top of the worktable. Based on a preset grinding trajectory and force, the position and height of the first robotic arm can be precisely controlled, enabling flexible movement of the grinding block within three-dimensional space. This ensures effective grinding of all parts of the wheel hub. One end of the first robotic arm is connected to the second robotic arm via a rotating connection, forming a multi-joint robotic arm structure. This enhances the flexibility and working range of the grinding mechanism, allowing the grinding block to more closely approximate the complex curved contours of the wheel hub for refined grinding. The entire grinding mechanism's movements are uniformly scheduled by the control system. Combining data from machine vision or sensors, the system adjusts the extension and retraction length of the electric push rods, the angles of the first and second robotic arms, and the pressure of the grinding block in real time. This truly automates and intelligentizes the grinding process. This grinding mechanism design facilitates comprehensive, high-precision grinding of automotive wheel hubs, significantly improving production efficiency and product quality while reducing the labor intensity and error rate of manual operation.

[0018] 4. This invention uses multiple vacuum suction cups attached to the inner wall of the wheel hub and introduced with negative pressure. Through the principle of vacuum adsorption, the wheel hub is firmly adsorbed. Even if there is a large impact or vibration during the grinding process, the wheel hub can be kept stable during grinding, avoiding displacement of the wheel hub during grinding, thus improving grinding accuracy and safety. The first connecting pipe is set as the main air passage, which delivers compressed air or vacuum source to each second connecting pipe, and then distributes it to each third connecting pipe and the vacuum suction cup at the end. This step-by-step connection method is conducive to centralized management and control of the airflow supply of all vacuum suction cups, ensuring that each vacuum suction cup can obtain sufficient suction to stably adsorb the wheel hub.

[0021] Please see Figures 1-9 A robot-assisted automated wheel polishing device includes a support mechanism 1 and a polishing mechanism 3 mounted on top of it. The support mechanism 1 includes a worktable 101, a rotating mechanism 2 rotatably connected to the center of the worktable 101, a clamping mechanism 4 for fixing the wheel hub connected to the top of the rotating mechanism 2, and an adsorption mechanism 5 connected to the top of the clamping mechanism 4. As a basic component, the support mechanism 1 provides a stable platform. The rotating mechanism 2 is set in the center of the workbench 101, which enables the wheel hub to rotate during the grinding process so that the grinding operation can be completed in all directions without dead angles. The rotating mechanism 2 ensures that the wheel hub can rotate smoothly at a constant speed to meet the dynamic requirements of the grinding process.

[0022] Furthermore, the clamping mechanism 4 includes a housing 401, a cover 402 connected to the top of the housing 401, a gear ring 405 rotatably connected to the inner wall of the cover 402, a plurality of bevel gears 403 meshing with the bottom of the gear ring 405, the bevel gears 403 being rotatably connected to the housing 401, a second motor 404 fixedly connected to one side of the housing 401, the output shaft of the second motor 404 extending into the housing 401 and fixedly connected to the inner wall of the bevel gears 403, and a movable [device] threadedly connected to the top of the gear ring 405. Block 406, the top of the movable block 406 extends above the shell cover 402 and is slidably connected to it, the top of the movable block 406 is fixedly connected to the positioning sleeve 407, the inside of the positioning sleeve 407 is slidably connected to the movable rod 408, one end of the movable rod 408 is fixedly connected to the clamping plate 409, the movable block 406 and the clamping plate 409 are fixedly connected to the first spring 411, the positioning sleeve 407 and the movable rod 408 are fixedly connected to the second spring 410, and one side of the clamping plate 409 is in contact with the inner wall of the wheel hub.

[0023] When a wheel hub needs to be processed, the operator can place the wheel hub on top of the placement tray 203 and then fix it in place. The operator can then start the second motor 404, which drives the bevel gear 403 to rotate. When the bevel gear 403 rotates, it drives the gear ring 405, which meshes with it, to rotate along the inner wall of the cover 402. As the gear ring 405 continues to rotate along the inner wall of the cover 402, since the top of the gear ring 405 is threadedly connected to the bottom of the moving block 406, the moving block 406 gradually moves away from the axis of the cover 402 along the surface of the cover 402. As the moving block 406 moves away from the axis of the cover 402, it drives the positioning sleeve 407, the movable rod 408, and the clamping plate 409 to gradually approach the inner wall of the wheel hub until one side of the clamping plate 409 is completely in contact with the inner wall of the wheel hub to be ground, making it convenient to grind. The wheel hub is effectively fixed by the clamping plate 409 at the end of the movable rod 408, which is tightly fitted to the inner wall of the wheel hub by the force of the first spring 411 and the second spring 410. This effectively clamps the wheel hub and can also make certain adaptive adjustments according to the wheel hub size, avoiding damage to the wheel hub due to excessive clamping force. Through the above design, this equipment can effectively clamp the wheel hub, ensuring that the subsequent grinding operation is carried out according to the predetermined trajectory and force, and ensuring that the surface flatness, roundness and roughness of the processed wheel hub meet high standards. Moreover, the adjustable clamping mechanism 4 can be adjusted according to the specific size of the wheel hub, ensuring that the wheel hubs of both small and large vehicles can be accurately and firmly fixed on the grinding device. This not only solves the compatibility problem of wheel hubs of various specifications, but also improves production efficiency and product quality, meeting the requirements of high efficiency, precision and flexibility of modern automated production lines.

[0024] Furthermore, the rotating mechanism 2 includes a first motor 201, the output end of which is fixedly connected to a rotating rod 202. One end of the rotating rod 202 extends above the worktable 101 and is rotatably connected thereto. The top of the rotating rod 202 is fixedly connected to a placement plate 203 for placing wheel hubs.

[0025] The placement plate 203 is used to support the wheel hub to be polished. When the first motor 201 is started, it drives the placement plate 203 and the wheel hub on it to rotate together through the rotating rod 202. In this way, when the robot or polishing tool polishes the wheel hub along a specific trajectory, the rotation of the wheel hub itself can ensure that all sides can be processed evenly and comprehensively, which greatly improves the polishing quality and efficiency.

[0026] Furthermore, a mounting base 105 is fixedly connected to the bottom of the workbench 101, and the mounting base 105 is fixedly connected to the first motor 201. Multiple support legs 104 are fixedly connected around the workbench 101.

[0027] The mounting base 105 is used to fix the first motor 201, ensuring the stability of the first motor 201 during operation and preventing the equipment from shifting or becoming unstable due to the force generated by the vibration or rotation of the first motor 201. The worktable 101 is rigidly connected to the first motor 201 through the mounting base 105, ensuring that the torque of the first motor 201 during operation can be directly and effectively transmitted to the rotating rod 202 and the placement plate 203, thereby enabling the hub to rotate stably. The multiple support legs 104 fixedly connected around the worktable 101 play the role of supporting the weight of the entire device and balancing the center of gravity, preventing the equipment from tipping over or being damaged due to the huge reaction force generated during the grinding process.

[0028] Furthermore, the grinding mechanism 3 includes a plurality of electric push rods 301 equidistantly arranged on the top of the worktable 101. The movable end of the electric push rod 301 is fixedly connected to a first robotic arm 302. One end of the first robotic arm 302 is rotatably connected to a second robotic arm 303. One end of the first robotic arm 302 is rotatably connected to a grinding block 304. The grinding block 304 is slidably connected to the outer surface of the wheel hub.

[0029] Multiple electric push rods 301 are equidistantly arranged on the top of the worktable 101. Based on preset grinding trajectories and pressures, they precisely control the position and height of the first robotic arm 302, enabling flexible movement of the grinding block 304 within three-dimensional space. This ensures effective grinding of all parts of the wheel hub. One end of the first robotic arm 302 is connected to the second robotic arm 303 via a rotating connection, forming a multi-joint robotic arm structure. This enhances the flexibility and working range of the grinding mechanism 3, allowing the grinding block 304 to more closely approximate the complex curved contours of the wheel hub for refined grinding. The entire grinding mechanism 3's movements are uniformly scheduled by the control system. Combining data from machine vision or sensor feedback, the system adjusts in real time the extension length of the electric push rods 301, the angles of the first and second robotic arms 302 and 303, and the pressure of the grinding block 304. This truly automates and intelligentizes the grinding process. This grinding mechanism design facilitates comprehensive, high-precision grinding of automotive wheel hubs, significantly improving production efficiency and product quality while reducing the labor intensity and error rate of manual operation.

[0030] Furthermore, a threaded block 305 is fixedly connected to the bottom of the electric push rod 301, and the threaded block 305 is slidably connected to the top of the worktable 101.

[0031] Furthermore, the workbench 101 has multiple mounting slots 102 equidistantly spaced on its surface. A threaded rod 306 is rotatably connected to the inner wall of the mounting slot 102, and the surface of the threaded rod 306 is threadedly connected to the inner wall of the threaded block 305.

[0032] By rotating the threaded rod 306, the operator can move the threaded block 305 along the surface of the threaded rod 306 using the thread transmission principle. This allows for precise adjustment of the height of the electric push rod 301 and its upper first robotic arm 302, second robotic arm 303, and grinding block 304. This facilitates detailed height adjustments based on the size of different wheel hubs and the varying depth requirements of the grinding task. Each mounting slot 102 and threaded rod 306 combine to form an independent adjustment module. If it is necessary to repair or replace a particular electric push rod 301, only the corresponding module needs to be operated without affecting the operation of other parts, thus improving the maintainability and expandability of the equipment.

[0033] Furthermore, a limiting groove 103 is provided on the inner wall of the mounting groove 102, and the limiting groove 103 is slidably connected to the threaded block 305.

[0034] The sliding connection structure between the limiting groove 103 and the threaded block 305 improves the functionality and safety of the height adjustment mechanism of the electric push rod 301, and enhances the overall performance and reliability of the automated grinding device for automobile wheel hubs.

[0035] Furthermore, the adsorption mechanism 5 includes a plurality of third connecting tubes 506 arranged at equal intervals. The two ends of the third connecting tubes 506 are fixedly connected to the adjacent moving blocks 406. A plurality of vacuum suction cups 507 are fixedly connected to one side of the third connecting tubes 506, and the plurality of vacuum suction cups 507 are in contact with the inner wall of the wheel hub.

[0036] Multiple vacuum suction cups 507 are attached to the inner wall of the wheel hub and negative pressure is introduced. Through the principle of vacuum adsorption, the wheel hub is firmly adsorbed. Even if there is a large impact or vibration during the grinding process, the wheel hub can be kept stable during grinding, avoiding displacement of the wheel hub during grinding, and improving grinding accuracy and safety.

[0037] Furthermore, a second connecting pipe 505 is fixedly connected to the top of the adjacent third connecting pipe 506, and a first connecting pipe 504 is fixedly connected to the top of the second connecting pipe 505. The first connecting pipe 504 is equidistantly arranged above the third connecting pipe 506.

[0038] The first connecting pipe 504 serves as the main air passage, delivering compressed air or a vacuum source to each of the second connecting pipes 505, and then distributing it to each of the third connecting pipes 506 and the vacuum suction cups 507 at the end. This step-by-step connection method facilitates centralized management and control of the airflow supply to all vacuum suction cups 507, ensuring that each vacuum suction cup 507 can obtain sufficient suction to stably adsorb the wheel hub.

[0039] Furthermore, a suction pipe 503 is fixedly connected to the top of a first connecting pipe 504, a vacuum pump 502 is fixedly connected to one end of the suction pipe 503, and a positioning plate 501 is fixedly connected to the bottom of the vacuum pump 502.

[0040] A positioning plate 501 is fixedly connected to the bottom of the vacuum pump 502. The positioning plate 501 serves to fix and support the vacuum pump 502, ensuring that the vacuum pump 502 is stable and does not shift during operation. At the same time, it can also minimize the vibration and noise generated by the vacuum pump 502 and maintain the overall stability of the equipment. This structural design not only ensures the effective operation of the adsorption mechanism, but also provides a reliable vacuum source support for the entire automated grinding device, improving the stability and safety of the wheel hub grinding process.

[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
