Through the setting of the fixing assembly, frames of different diameters can be fixed, improving the overall applicability.

[0037] Please refer to Figures 2 - 7 As shown in [the figure], among them, the polishing assembly includes: a polishing ring 6, an electric push rod 603, a fixing block 7, a polishing wheel 703 and an annular pipe 8; a polishing ring 6 provided on one side of the fixing ring 5, and a plurality of receiving grooves 602 are opened on the inner wall of the polishing ring 6; an electric push rod 603 installed inside the receiving groove 602, and one end of the electric push rod 603 is fixedly connected to a fixing block 7; a servo motor 701 installed on one side of the fixing block 7, a rotating rod 702 is provided on one side of the servo motor 701, and a polishing wheel 703 is connected to the rotating rod 702. One side of the polishing ring 6 is fixedly connected to an annular pipe 8, and a plurality of water injection pipes 801 are connected to the inside of the annular pipe 8. A rotating groove 502 is opened inside the fixing ring 5, and a driving ring 601 connected to the polishing ring 6 is provided inside the rotating groove 502. A servo motor 503 is provided inside the rotating groove 502, and a driving wheel 504 is provided on one side of the servo motor 503, and the driving wheel 504 is meshed with the driving ring 601.

[0038] When polishing the frame, the servo motor 701 can drive the rotating rod 702 to rotate, so that the rotating rod 702 drives the polishing wheel 703 to rotate. At the same time, the electric push rod 603 is used to push the fixed block 7 and the polishing wheel 703 to move, so that the polishing wheel 703 contacts the surface of the frame and performs the polishing operation. During the polishing process, the servo motor 503 can drive the driving wheel 504 to rotate, so that the driving wheel 504 drives the driving ring 601 to rotate, and then drives the polishing ring 6 to rotate, so that multiple polishing wheels 703 perform all-round polishing operations on the surface of the frame.

[0039] Please refer to Figures 11 - 12 Furthermore, a transmission groove 705 is formed inside the fixed block 7, a transmission plate 706 is arranged inside the transmission groove 705, a cam 704 is connected to the outer side of the rotating rod 702, and the cam 704 is located inside the transmission groove 705. A return spring 707 is connected to the top of the transmission plate 706. A cavity 708 is formed inside the fixed block 7, a water spray pipe 709 is connected to the bottom of the cavity 708. One side of the transmission plate 706 is provided with a transmission rod 7061 through a rotating shaft, and one end of the transmission rod 7061 is provided with a blocking block 7062 through a rotating shaft. The water spray pipe 709 corresponds to the position of the polishing wheel 703. One side of the water injection pipe 801 is connected with a shunt pipe 804, and one end of the shunt pipe 804 communicates with the cavity 708.

[0040] During the polishing process, the rotating rod 702 drives the cam 704 to rotate, and the transmission plate 706 always adheres to the surface of the cam 704 under the action of the elastic force of the return spring 707, so that the transmission plate 706 moves up and down as the cam 704 rotates. When the transmission plate 706 moves towards the cam 704, the transmission plate 706 drives one end of the transmission rod 7061 to move, so that the other end of the transmission rod 7061 drives the blocking block 7062 to move backward, thereby opening the water spray pipe 709, so that the water inside the cavity 708 can be sprayed out through the water spray pipe 709 and sprayed onto the polishing wheel 703. On the one hand, it can reduce the heat generated by friction during the polishing process of the polishing wheel 703 and extend the service life of the polishing wheel 703. On the other hand, it can wash away the impurities generated by polishing on the polishing wheel 703 and wet the polishing wheel 703, thereby reducing the dust generated by polishing. When the transmission plate 706 moves away from the cam 704, the transmission plate 706 drives the blocking block 7062 to reset through the transmission rod 7061, so that the blocking block 7062 re-blocks the water spray pipe 709.

[0041] Please refer to Figure 2 、 Figure 5 、 Figure 6 and Figure 15, wherein, the dust removal assembly includes: a fixing plate 802, a spray head 803, a device block 102 and a waste cavity 401; the fixing plate 802 connected to one side of the fixing block 7, a spray head 803 is provided on the side of the fixing plate 802 away from the annular pipe 8, and the spray head 803 is inclined towards the polishing wheel 703, and the water injection pipe 801 communicates with the spray head 803; the device block 102 is arranged above the workbench 101, a water storage cavity 103 is opened inside the device block 102, a waste cavity 401 is opened inside the workbench 101, a waste water tank 402 is arranged inside the waste cavity 401, a water inlet pipe 104 communicating with the water storage cavity 103 is provided on the top of the box body 1, a water pump 105 is arranged inside the water storage cavity 103, the bottom of the water pump 105 is connected with a water pipe 106, and the bottom end of the water pipe 106 communicates with the annular pipe 8, a filter frame 404 is arranged on the top of the waste water tank 402, a vacuum pump 403 is arranged inside the workbench 101, the air extraction end of the vacuum pump 403 communicates with the waste cavity 401, a plurality of air extraction grooves 501 are opened on the inner wall of the fixed ring 5, and the bottom wall of the air extraction groove 501 is inclined, a telescopic conduit 405 is arranged inside the fixed ring 5, and one end of the telescopic conduit 405 communicates with the plurality of air extraction grooves 501, and the other end of the telescopic conduit 405 communicates with the waste cavity 401.

[0042] During the polishing process, a large amount of floating dust impurities will be generated due to the friction between the polishing wheel 703 and the surface of the vehicle frame, polluting the working environment. At this time, the water in the water storage cavity 103 can be discharged into the annular pipe 8 through the water pipe 106 by the water pump 105, and enter into the plurality of water injection pipes 801, and be injected into the spray head 803 through the water injection pipe 801. The spray head 803 is inclined towards the polishing wheel 703 and corresponds to the position of the polishing wheel 703, so that the spray head 803 can accurately spray water onto the polishing area between the polishing wheel 703 and the vehicle frame, thereby reducing the situation of dust floating. At the same time, the water sprayed by the inclined spray head 803 can carry the dust generated by polishing into the fixed ring 5; Then, the gas inside the waste cavity 401 is pumped away by the vacuum pump 403, so that the air pressure inside the waste cavity 401 drops to generate suction, and the generated suction acts on the air extraction grooves 501 through the telescopic conduit 405. At this time, the water mist inside the fixed ring 5 will be sucked into the air extraction grooves 501, and be discharged into the waste cavity 401 through the telescopic conduit 405. Part of the water mist will contact the inner wall of the fixed ring 5 to form water droplets, and slide down along the inner wall of the fixed ring 5 into the air extraction grooves 501, and be pumped away by the telescopic conduit 405. Then, air holes are opened at the top of the waste cavity 401, so that the dust and water mist floating inside the box body 1 can be sucked into the waste cavity 401 through the air holes. Then, through the setting of the filter frame 404, the dust impurities in the water mist or gas can be filtered, and the filtered sewage drops into the waste water tank 402 for centralized collection.

[0043] Please refer to Figure 2A movable groove 3 is provided on the top of the workbench 101, a driving motor 301 is provided inside the workbench 101, a driving rod 302 is provided on one side of the driving motor 301, and one end of the driving rod 302 is connected to the movable groove 3 through a bearing, a driving block 303 is connected to the bottom of the base 4, and the driving block 303 is located in the movable groove 3, a thread is provided on the driving rod 302, and a threaded hole communicating with the driving rod 302 is provided on the driving block 303.

[0044] During polishing, the driving motor 301 can be used to drive the driving rod 302 to rotate, so that the driving rod 302 drives the driving block 303 to move under the action of the threaded engagement of the threaded hole, and then the driving block 303 drives the base 4 and the fixing ring 5 to move laterally, thereby changing the positions of the fixing ring 5 and the polishing ring 6, and then polishing the surface of the frame.

[0045] See also Figure 2 , Figure 4 , Figure 8 and Figure 9 , wherein the fixed component includes: a mounting plate 201, a rotating plate 203 and a slide groove 208; a mounting plate 201 mounted on one side of the fixed plate 2, a rotating motor 202 is provided on the top of the mounting plate 201; a rotating cavity is opened inside the fixed plate 2, and a rotating plate 203 is arranged inside the rotating cavity; a plurality of slide grooves 208 are opened on one side of the fixed plate 2, and a clamping block 206 is slidably connected inside the slide groove 208, and the plurality of slide grooves 208 are evenly distributed in a circular array, the rotating plate 203 is connected to the driving end of the rotating motor 202, a plurality of rotating grooves 204 are opened on one side of the rotating plate 203 close to the clamping block 206, and the rotating grooves 204 are inclined, a plurality of slots 209 are opened inside the fixed plate 2, and the slots 209 are respectively communicated with the slots 208 and the rotating cavity, a toggle block 205 is connected to one end of the clamping block 206, and the toggle block 205 extends into the rotating groove 204 through the slot 209.

[0046] Before polishing the frame, it is necessary to fix the frame. At this time, the frame is passed through the fixing ring 5, and the two ends of the frame are located on the sides of the fixing plate 2. At this time, the rotating plate 203 is driven to rotate by the rotating motor 202, so that the rotating groove 204 on the rotating plate 203 contacts the toggle block 205, and drives the toggle block 205 to move. Due to the setting of the slot 209, the moving direction and distance of the toggle block 205 are limited, so that the toggle block 205 can only move along the direction of the slot 209, so that the toggle block 205 can move in the direction of the rotating plate 203. The rotating plate 203 moves inward or from inside to outside, thereby driving the multiple clamping blocks 206 to move toward the frame to clamp and fix it, or move away from the frame to release the fixation of the frame. The provision of the rubber plate 207 can increase the friction coefficient with the frame, ensure the stability of the frame when it is clamped and fixed, and avoid the vibration generated during the polishing process to cause the frame to rotate or shift in position, thereby affecting the polishing quality. At the same time, the provision of multiple clamping blocks 206 can clamp and fix frames of different diameters, thereby improving applicability.

[0047] Furthermore, the cross-section of one end of the toggle block 205 is T-shaped, and the cross-sectional size of one end of the toggle block 205 matches the cross-sectional profile of the rotating groove 204. A rubber plate 207 is provided on the surface of the clamping block 206. Through the setting of the T-shaped structure, the toggle block 205 can be prevented from falling off from the rotating groove 204.

[0048] Working principle: Before polishing the frame, it is necessary to fix the frame. At this time, the frame is passed through the fixing ring 5, and the two ends of the frame are located on the sides of the fixing plate 2. At this time, the rotating plate 203 is driven to rotate by the rotating motor 202, so that the rotating groove 204 on the rotating plate 203 contacts the toggle block 205, and drives the toggle block 205 to move. Due to the setting of the slot 209, the moving direction and distance of the toggle block 205 are limited, so that the toggle block 205 can only move along the direction of the slot 209, so that the toggle block 205 can move in the direction of the rotating plate 203. The rotating plate 203 moves inward or from the inside to the outside, thereby driving the multiple clamping blocks 206 to move toward the frame to clamp and fix it, or move away from the frame to release the fixation of the frame. The setting of the rubber plate 207 can increase the friction coefficient with the frame, ensure the stability of the frame when clamped and fixed, and avoid the vibration generated during the polishing process to cause the frame to rotate or shift in position, affecting the polishing quality. At the same time, the setting of multiple clamping blocks 206 can clamp and fix frames of different diameters, thereby improving applicability. After the frame is fixed, the servo motor 701 can drive the rotating rod 702 to rotate, so that the rotating rod 702 drives the polishing wheel 703 to rotate. At the same time, the electric push rod 603 is used to push the fixing block 7 and the polishing wheel 703 to move, so that the polishing wheel 703 contacts the surface of the frame and performs polishing operations. During the polishing process, the servo motor 503 can drive the driving wheel 504 to rotate, so that the driving wheel 504 drives the driving ring 601 to rotate, and then drives the polishing ring 6 to rotate, so that multiple polishing wheels 703 perform all-round polishing operations on the surface of the frame; During the polishing process, a large amount of floating dust impurities will be generated due to the friction between the polishing wheel 703 and the surface of the frame, polluting the working environment. At this time, the water pump 105 can discharge the water in the water storage cavity 103 into the annular pipe 8 through the water pipe 106, and enter into multiple water injection pipes 801, and be injected into the nozzle 803 through the water injection pipe 801. The nozzle 803 is inclined towards the polishing wheel 703 and corresponds to the position of the polishing wheel 703, so that the nozzle 803 can accurately spray water onto the polishing area between the polishing wheel 703 and the frame, thereby reducing the situation of dust floating. At the same time, the water sprayed by the inclined nozzle 803 can carry the dust generated by polishing towards the fixing ring 5; Then, the vacuum pump 403 is used to pump out the gas inside the waste cavity 401, so that the air pressure inside the waste cavity 401 drops to generate suction. The generated suction acts on the air extraction groove 501 through the telescopic conduit 405. At this time, the water mist inside the fixing ring 5 will be sucked into the air extraction groove 501 and discharged into the waste cavity 401 through the telescopic conduit 405. Part of the water mist will contact the inner wall of the fixing ring 5 to form water droplets, and slide down along the inner wall of the fixing ring 5 into the air extraction groove 501 and be pumped away by the telescopic conduit 405. Then, air holes are provided at the top of the waste cavity 401, so that the dust and water mist floating inside the box body 1 can be sucked into the waste cavity 401 through the air holes. Then, through the setting of the filter frame 404, the dust impurities in the water mist or gas can be filtered, and the filtered sewage will fall into the waste water tank 402 for centralized collection; Meanwhile, the water in the water injection pipe 801 is injected into the interior of the cavity 708 through the shunt pipe 804. When the rotating rod 702 drives the cam 704 to rotate, the transmission plate 706 always adheres to the surface of the cam 704 under the action of the elastic force of the return spring 707, so that the transmission plate 706 moves up and down as the cam 704 rotates. When the transmission plate 706 moves towards the cam 704, one end of the transmission rod 7061 is driven to move by the transmission plate 706, so that the other end of the transmission rod 7061 drives the plug block 7062 to move backward, thereby opening the water spray pipe 709, enabling the water inside the cavity 708 to be sprayed out through the water spray pipe 709 and onto the polishing wheel 703. On the one hand, it can reduce the heat generated by friction during the polishing process of the polishing wheel 703 and extend the service life of the polishing wheel 703. On the other hand, it can wash away the impurities generated by polishing on the polishing wheel 703 and wet the polishing wheel 703, thereby reducing the dust generated by polishing. When the transmission plate 706 moves away from the cam 704, the transmission plate 706 drives the plug block 7062 to reset through the transmission rod 7061, so that the plug block 7062 re-seals the water spray pipe 709; Next, the driving motor 301 can be used to drive the driving rod 302 to rotate, so that the driving rod 302 drives the driving block 303 to move under the action of the screw thread engagement in the threaded hole, and then the driving block 303 drives the base 4 and the fixing ring 5 to move horizontally, thereby changing the positions of the fixing ring 5 and the polishing ring 6, and then polishing the surface of the vehicle frame.
