By integrating polishing and grinding into one machine, multiple process steps can be completed at once, improving production efficiency.

[0003] A Chinese patent with publication number CN206010684U discloses an automotive mirror edging and polishing device, comprising: an operating table, and an edging mechanism and a polishing mechanism disposed on the operating table; wherein the edging mechanism includes a first automotive mirror fixing mechanism and an automotive mirror grinding mechanism; the polishing mechanism includes a second automotive mirror fixing mechanism and an automotive mirror polishing mechanism; and the first and second automotive mirror fixing mechanisms are both used to fix the automotive mirror and are driven to rotate the automotive mirror by a brushless DC torque motor disposed below the operating table; the automotive grinding mechanism includes a grinding frame for grinding the edge of the automotive mirror; the automotive polishing mechanism includes a polishing frame for grinding the edge of the automotive mirror. This automotive mirror edging and polishing device, through its integrated edging and polishing mechanism, saves time and labor, and improves processing efficiency.

[0004] Existing integrated polishing and grinding equipment for automotive trim parts is not conducive to effectively collecting and processing impurities generated during the polishing and grinding process. This not only causes impurities to accumulate in the work area, but also increases the difficulty and labor intensity of subsequent manual cleaning, affecting work efficiency and environmental hygiene.

[0005] Therefore, the present invention provides an integrated polishing and grinding device for automotive decorative parts. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies and solve the problem of the inconvenience of collecting and accumulating debris generated during processing, this invention proposes an integrated polishing and grinding device for automotive decorative parts.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: An integrated polishing and grinding device for automotive decorative parts, comprising a worktable, a limiting mechanism for positional correction of the automotive decorative parts, a controller on the side of the worktable, a collection mechanism for collecting polishing debris inside the worktable, a frame fixedly mounted on the top of the worktable, observation windows symmetrically arranged on the frame, a push rod fixedly mounted on the top of the frame, a mounting frame inside the frame, and the push rod fixedly connected to the mounting frame, grinding wheels symmetrically arranged inside the mounting frame, a polishing component for polishing the automotive decorative parts inside the mounting frame, a pulley fixedly connected to the center of the grinding wheel, and adjacent pulleys connected by belt drive, a dual-shaft motor fixedly mounted on the top of the mounting frame, one output end of the dual-shaft motor fixedly connected to the center of the pulley, a strip frame fixedly mounted on the top of the mounting frame, a ventilation mechanism inside the strip frame, and positioning mechanisms symmetrically arranged on the mounting frame.

[0008] By employing the above scheme, after the trim piece is moved below the grinding wheel, the dual-shaft motor drives the pulley to rotate. The rotation of the pulley drives the grinding wheel to rotate, and the position of the trim piece is positioned by the limiting mechanism. Simultaneously, the first push rod moves the mounting bracket, which adjusts the position of the grinding wheel. Once the grinding wheel lowers and contacts the surface of the trim piece, it can grind it. The rotation of the grinding wheel, through centrifugal force, causes the grinding debris to flow into the dust collection trough. The dual-shaft motor, while operating, drives the suction mechanism, which generates suction that draws the dust through the dust collection trough. Floating debris is collected and processed. After grinding one side of the car trim, the trim is moved further until the grinding area is below the polishing assembly. Then, the first push rod adjusts the position of the grinding wheel and the polishing assembly, so that they contact the trim. The grinding wheel continues to grind the trim, while the polishing assembly polishes the ground area. The positioning mechanism positions the trim. Debris generated during polishing flows due to inertia, and most of the debris is collected by the collection mechanism.

[0009] Preferably, the exhaust mechanism includes an exhaust fan, a drive wheel, an exhaust pipe, a connecting groove, a telescopic hose, and a dust collection assembly. The exhaust fan is fixedly installed inside the strip frame. The center of the drive wheel is fixedly connected to the impeller inside the exhaust fan via a shaft. The exhaust pipe is embedded inside the strip frame, and one end of the exhaust pipe is connected to the input end of the exhaust fan. The connecting groove is fixedly installed inside the strip frame, and the other end of the exhaust pipe is connected to the connecting groove. One end of the telescopic hose is fixedly connected to the connecting groove. The dust collection assembly is installed on the frame. An exhaust groove is embedded inside the mounting frame, and the output end of the exhaust fan is connected to the exhaust groove via a pipe. The mounting frame has symmetrically arranged grooves inside, and the grooves are connected to the exhaust grooves. Spray nozzles are arranged in an array on the grooves.

[0010] By adopting the above scheme, the dual-axis motor drives the first drive wheel to rotate, which in turn drives the rotating wheel. The rotating wheel and the transmission wheel are connected by a belt drive, which drives the transmission wheel to rotate synchronously. When the transmission wheel rotates, it drives the exhaust fan to move, drawing air from inside the connecting slot through the exhaust pipe. With the cooperation of the telescopic hose and the dust collection component, the air can be drawn in, and the airflow will carry floating objects into the dust collection component. The dust collection component can collect and process the floating objects generated during grinding and polishing. At the same time, the airflow drawn in by the exhaust fan will enter the exhaust slot, and the exhaust slot will cause the airflow to enter the slot. Through the nozzle, the airflow will be directed to the surface of the workbench, and the airflow will flow to the dust collection component. The airflow will also help the floating objects to flow to the dust collection component, which can further process the floating objects, improving cleanliness.

[0011] Preferably, the dust collection assembly includes a dust collection groove, a conical groove, an air extraction groove, a connecting pipe, an air extraction head, and a filter screen. The dust collection groove is symmetrically embedded inside the frame. The conical groove is located at the bottom of the dust collection groove. The air extraction groove is symmetrically arranged on the frame. The connecting pipe is embedded inside the frame, with one end connected to the air extraction groove and the other end connected to a telescopic flexible hose. The air extraction head array is arranged on the air extraction groove, with one end of the air extraction head extending into the dust collection groove. The filter screen is located on one side of the air extraction head. The workbench is symmetrically provided with discharge grooves, and the top of the discharge groove is connected to the bottom of the conical groove.

[0012] By adopting the above scheme, when the exhaust fan operates to extract air from the connecting groove, the air inside the extraction groove can be extracted through the cooperation of the telescopic hose and the connecting pipe. Then, the extraction head can extract air from the dust collection groove, which will generate suction in the dust collection groove. After the outside air flows into the dust collection groove, it will flow towards the extraction head. Impurities can be filtered and intercepted through the filter screen. The filtered and intercepted impurities will fall into the conical groove. The collected debris and impurities can flow into the discharge groove through the conical groove. The discharge groove will cause the debris to flow into the collection mechanism for storage, thus achieving the purpose of collecting the debris generated by grinding and polishing.

[0013] Preferably, a controller is provided on the side of the workbench, and the limiting mechanism includes a support plate, a support block, a second push rod, a square block, and a rotating roller. The support plate is fixedly provided on the side of the workbench, the support blocks are symmetrically provided on the support plate, the second push rod is fixedly provided on the support block, the square blocks are symmetrically provided on the support plate and located on one side of the support block, one end of the second push rod is fixedly connected to the square block, and the rotating roller array is rotatably provided on the square block.

[0014] By adopting the above scheme, after the car trim part is moved to the polishing location, the section of the car trim part that has not entered the polishing area will be located on one side of the square block. By controlling the operation of the second push rod, the square block will be pushed to move. When the square block moves, it will drive the rotating roller to move. The rotating roller moves and contacts the surface of the car trim part, thereby positioning the car trim part.

[0015] Preferably, a permanent magnet is fixedly embedded inside the grinding wheel, and mounting plates corresponding to the grinding wheel are symmetrically arranged inside the mounting frame. A cylinder is symmetrically arranged inside the mounting plate, and a magnetic block is slidably arranged inside the cylinder. A connecting rod is fixedly connected to the center of the magnetic block. A limit block is fixedly installed inside the cylinder, and the connecting rod passes through the limit block. A striking block is arranged inside the cylinder, and one end of the connecting rod is fixedly connected to the center of the striking block. A return spring is arranged around the limit block, and the connecting rod passes through the return spring. The other end of the return spring is fixedly connected to the striking block. A through hole is provided at the center of the mounting plate.

[0016] By adopting the above scheme, the rotation of the grinding wheel will drive the permanent magnet to rotate. After the permanent magnet moves directly above the magnetic block, it will attract the magnetic block to move. The movement of the magnetic block will drive the connecting rod and the striking block to move. The striking block will squeeze the return spring. After the grinding wheel continues to rotate and moves away from above the magnetic block, the return spring will return to its original position and push the striking block to return to its original position. The return of the striking block and its contact with the magnetic block will cause the mounting bracket to vibrate slightly, thereby vibrating and removing the impurities adsorbed on the mounting bracket. At the same time, the positioning mechanism can transmit the vibration to the automotive trim parts, causing the automotive trim parts to vibrate slightly, which can remove the impurities adsorbed on the automotive trim parts and improve the cleanliness of the automotive trim parts.

[0017] Preferably, the strip frame is provided with an annular groove, and a rotating wheel is rotatably arranged inside the annular groove. The rotating wheel is connected to a transmission wheel via a belt. The other output end of the dual-shaft motor is fixedly connected to a first drive wheel, and the first drive wheel is connected to the rotating wheel via a belt.

[0018] By adopting the above scheme, the dual-output shaft motor drives the first drive wheel to rotate. The rotation of the first drive wheel drives the rotating wheel to rotate via the belt, and then drives the exhaust fan to move via the transmission wheel.

[0019] Preferably, the polishing assembly includes a frame, a rotating shaft, a polishing belt, a second drive wheel, and a driven component. The frame is embedded inside the mounting frame. The rotating shaft is rotatably disposed inside the strip frame, and the other end of the rotating shaft is rotatably connected to the frame. The polishing belt is arranged around the rotating shaft. The array of second drive wheels is disposed inside the frame, and the center position of the second drive wheel is fixedly connected to one end of the rotating shaft. Adjacent second drive wheels are connected by belt drive. The driven component for driving the second drive wheel to rotate is disposed on the frame.

[0020] By adopting the above scheme, the rotation of the pulley drives the driven component to move via the belt, the movement of the driven component drives the second drive wheel to rotate, the rotation of the second drive wheel drives the rotating shaft to move, the rotation of the rotating shaft causes the polishing belt to move, and the polishing belt can then polish the automotive trim parts.

[0021] Preferably, the driven component includes a support shaft, a worm gear, a worm, a transmission rod, and a third drive wheel. The support shaft is rotatably disposed inside the frame, and one end of the support shaft is fixedly connected to the center position of the corresponding second drive wheel. The worm gear is fixedly disposed on the support shaft. The worm is rotatably disposed inside the frame, and the worm and the worm gear mesh with each other. One end of the transmission rod is fixedly connected to the worm, and the other end of the transmission rod extends out of the frame. The center position of the third drive wheel is fixedly connected to one end of the transmission rod, and the third drive wheel is connected to the pulley via a belt drive.

[0022] By adopting the above scheme, when the pulley rotates, it will drive the third drive wheel to rotate. When the third drive wheel rotates, it will drive the worm to rotate through the transmission rod. The rotation of the worm will drive the worm wheel to rotate. The rotation of the worm wheel will drive the second drive wheel to rotate. The adjacent second drive wheels are connected by belt drive, which will drive the other second drive wheels to rotate synchronously.

[0023] Preferably, the storage mechanism includes a support frame, a power motor, conveying rollers, a collection trough, a slide trough, and a storage slot. The collection trough is located inside the workbench, the support frame is symmetrically arranged inside the collection trough, the power motor is embedded inside the workbench, the conveying roller array is rotatably mounted on the support frame, and one end of each adjacent conveying roller is provided with a wheel body connected by a belt drive. The output end of the power motor is fixedly connected to one of the conveying rollers via a shaft. The slide trough is located at the bottom of the workbench and is connected to the collection trough. The collection trough is conical in shape, and the storage slot passes through the interior of the slide trough.

[0024] By adopting the above solution, the collection trough is supported by the support frame for the conveyor roller. When the power motor is working, it will drive the conveyor roller to rotate. The rotation of the conveyor roller can assist in the movement of the car trim parts supported on the top, and can assist in the grinding and polishing of the car trim parts. During the grinding and polishing process, the debris falls downward into the collection trough. The collection trough is conical, which will allow the debris to flow into the storage trough for collection and storage.

[0025] Preferably, the positioning mechanism includes a third push rod and a positioning block. The third push rod is fixedly installed inside the mounting frame, and the positioning block is installed on one side of the grinding wheel. One end of the third push rod is fixedly connected to the positioning block.

[0026] By adopting the above scheme, the No. 3 push rod will push the positioning block to move. After the positioning block moves and contacts the top of the car trim part, it will position the car trim part, which will facilitate the grinding and polishing of the car trim part. At the same time, when the mounting bracket generates slight vibration, the No. 3 push rod and the positioning block can cooperate to transmit the vibration to the car trim part, which will cause the car trim part to vibrate, thus cleaning the car trim part and preventing impurities from adhering to the car trim part, thereby improving the grinding quality of the car trim part.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. The present invention provides an integrated polishing and grinding device for automotive trim parts. The device features a dust collection trough and a trough body to facilitate the collection and removal of debris generated during polishing, preventing impurities from accumulating and affecting the cleanliness of the work area. The rotating grinding wheel, through centrifugal force, causes the polishing debris to flow into the dust collection trough. When the dual-shaft motor operates, it drives the primary drive wheel to rotate, which in turn drives the transmission wheel to rotate synchronously, causing the exhaust fan to move and generating suction in the dust collection trough. After outside air flows into the dust collection trough, impurities are filtered and intercepted by a filter screen, and the filtered impurities fall into the conical trough. The conical groove allows collected debris and impurities to flow into the discharge trough, while the airflow from the exhaust fan flows into the exhaust trough. The nozzle directs the airflow onto the worktable surface, and the airflow helps floating debris flow into the dust collection trough. The dust collection trough further processes the floating debris, achieving the purpose of automatically collecting the debris generated during polishing of automotive trim parts. This effectively prevents dust from flying in the work area, affecting the cleanliness of the production environment and the health of workers. It also prevents debris from re-adhering to the surface of the trim parts, affecting the polishing quality and causing secondary pollution.

[0029] 2. The polishing and grinding integrated device for automotive trim parts described in this invention uses a cylindrical barrel and a striking block to facilitate vibration of the mounting frame, thereby aiding in the removal and collection of debris. This prevents excessive debris from being generated during grinding, which could affect the quality of the automotive trim parts. When the grinding wheel rotates, it drives the permanent magnet to rotate. After the permanent magnet moves directly above the magnetic block, it attracts the magnetic block to move. The movement of the magnetic block drives the connecting rod and the striking block to move. The striking block compresses the return spring. As the grinding wheel continues to rotate and moves away from above the magnetic block, the return spring resets, pushing the striking block to reset. The resetting striking block contacts and collides with the magnetic block, causing slight vibration of the mounting frame. This facilitates the removal of impurities adsorbed on the mounting frame, effectively preventing impurities from adsorbing on the mounting frame and preventing debris from interfering with the grinding effect and affecting the surface quality of the trim parts.

[0030] 3. The integrated polishing and grinding device for automotive trim parts described in this invention, through the setting of a third push rod and a positioning block, facilitates the vibration of the automotive trim parts when the mounting frame vibrates, thereby removing impurities adsorbed on the surface of the automotive trim parts and improving the cleanliness of the automotive trim parts. The operation of the third push rod will push the positioning block to move. After the positioning block contacts the top of the automotive trim parts, it will position the automotive trim parts. When the mounting frame vibrates slightly, the third push rod and the positioning block can cooperate to transmit the vibration to the automotive trim parts, thereby causing the automotive trim parts to vibrate and perform a cleaning treatment on the automotive trim parts, preventing impurities from adsorbing on the automotive trim parts and improving the grinding quality of the automotive trim parts.

[0031] 4. The integrated polishing and grinding device for automotive decorative parts described in this invention facilitates the collection and processing of debris through the set discharge trough and collection trough, preventing debris from affecting the working area. The conical trough allows the collected debris and impurities to flow into the discharge trough, and the discharge trough allows the debris to flow into the collection mechanism for storage. During polishing, the debris falls downwards into the collection trough, which is conical, allowing the debris to flow into the collection trough for collection and storage, thus maintaining the cleanliness of the working area.

[0032] 5. The integrated polishing and grinding device for automotive trim parts described in this invention, through the setting of grinding wheels and polishing belts, can achieve synchronous or coordinated operation of polishing and grinding using the same power source, ensuring smoother process coordination, improving processing efficiency and surface quality. Furthermore, by integrating the two processes of polishing and grinding into one, multiple steps can be completed in one operation, saving equipment changeover and process time, thereby significantly improving the overall production speed of the integrated polishing and grinding device for automotive trim parts.

[0046] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0047] like Figures 1 to 11 As shown in the embodiment of the present invention, a polishing and grinding integrated device for automotive trim parts includes a worktable 1. The worktable 1 is equipped with a limiting mechanism for positional correction of the automotive trim parts. A controller 2 is located on the side of the worktable 1. A collection mechanism for collecting polishing debris is located inside the worktable 1. A frame 8 is fixedly mounted on the top of the worktable 1. Observation windows 10 are symmetrically arranged on the frame 8. A push rod 9 is fixedly mounted on the top of the frame 8. A mounting bracket 11 is located inside the frame 8, and the push rod 9 is fixedly connected to the mounting bracket 11. The mounting frame 11 has symmetrically arranged grinding wheels 12 inside, and a polishing component for polishing automotive trim parts is also provided inside the mounting frame 11. A pulley 22 is fixedly connected to the center of the grinding wheel 12, and adjacent pulleys 22 are connected by belt drive. A dual-shaft motor 23 is fixedly installed on the top of the mounting frame 11, and one of the output ends of the dual-shaft motor 23 is fixedly connected to the center of the pulley 22. A strip frame 25 is fixedly installed on the top of the mounting frame 11, and a ventilation mechanism is provided inside the strip frame 25. A positioning mechanism is symmetrically arranged on the mounting frame 11.

[0048] Push rod 9, push rod 5, and push rod 35 are all electric push rods. Controller 2 is electrically connected to the electronic components on the integrated polishing and grinding device for automotive trim parts, and can control the operation of the integrated polishing and grinding device for automotive trim parts. The electronic components on the integrated polishing and grinding device for automotive trim parts are electrically connected to an external power source.

[0049] When polishing and grinding automotive trim parts using the integrated polishing and grinding device, the trim part to be polished is manually placed on the support plate 3. The trim part is then moved until it is below the grinding wheel 12. The dual-shaft motor 23 then drives the pulley 22 to rotate, which in turn drives the grinding wheel 12. Through the movement of the limiting mechanism, the position of the trim part is positioned. Simultaneously, the first push rod 9 moves the mounting bracket 11, which adjusts the position of the grinding wheel 12 until it contacts the surface of the trim part. The grinding wheel 12 then grinds the trim part. The rotation of the grinding wheel 12, through centrifugal force, causes the grinding debris to flow into the dust collection trough 43. The dual-shaft motor 23, while operating, drives the suction mechanism, which generates suction to draw out the debris. The dust collection trough 43 can collect and process floating objects generated during polishing. After polishing one side of the car trim, the car trim continues to move, so that the polishing area is moved below the polishing assembly. Then, the first push rod 9 adjusts the position of the polishing wheel 12 and the polishing assembly, so that the polishing wheel 12 and the polishing assembly contact the car trim respectively. The polishing wheel 12 continues to polish the car trim, and the movement of the polishing assembly polishes the area of ​​the car trim after polishing. The movement of the polishing assembly can continue to polish the car trim. The movement of the positioning mechanism can position the car trim. The debris generated during polishing will flow due to inertia. Most of the debris is collected by the collection mechanism during polishing. The uncollected debris will flow to the side of the dust collection trough 43 due to inertia. The dust collection trough 43 can further collect and process the debris, keeping the work area clean.

[0050] Furthermore, the exhaust mechanism includes an exhaust fan 38, a drive wheel 39, an exhaust pipe 40, a connecting groove 41, a telescopic hose 42, and a dust collection component. The exhaust fan 38 is fixedly installed inside the strip frame 25. The center of the drive wheel 39 is fixedly connected to the impeller inside the exhaust fan 38 via a shaft. The exhaust pipe 40 is embedded inside the strip frame 25, and one end of the exhaust pipe 40 is connected to the input end of the exhaust fan 38. The connecting groove 41 is fixedly installed inside the strip frame 25, and the other end of the exhaust pipe 40 is connected to the connecting groove 41. One end of the telescopic hose 42 is fixedly connected to the connecting groove 41. The dust collection component is installed on the frame 8. The mounting bracket 11 has an exhaust groove 52 embedded inside, and the output end of the exhaust fan 38 is connected to the exhaust groove 52 via a pipe. The mounting bracket 11 has symmetrically arranged grooves 53 inside, and the grooves 53 are connected to the exhaust grooves 52. The grooves 53 are arranged in an array with nozzles 54.

[0051] When the dual-shaft motor 23 is working, it drives the first drive wheel 24 to rotate, which in turn drives the rotating wheel 37 to rotate. The rotating wheel 37 is connected to the transmission wheel 39 via a belt drive, which drives the transmission wheel 39 to rotate synchronously. When the transmission wheel 39 rotates, it drives the exhaust fan 38 to move. The exhaust pipe 40 draws air from the inside of the connecting groove 41. Through the telescopic hose 42 and the dust collection component, the air can be drawn in. As the air flows, it carries floating objects into the dust collection component. The dust collection component can collect and process the floating objects generated during grinding and polishing. At the same time, the airflow drawn by the exhaust fan 38 enters the exhaust groove 52. The exhaust groove 52 causes the airflow to enter the groove 53. Through the nozzle 54, the airflow is directed to the surface of the workbench 1. The airflow is directed to the dust collection component. The airflow helps the floating objects to flow to the dust collection component. The dust collection component can further process the floating objects, improving cleanliness.

[0052] Furthermore, the dust collection assembly includes a dust collection groove 43, a conical groove 44, an air extraction groove 45, a connecting pipe 46, an air extraction head 47, and a filter screen 48. The dust collection groove 43 is symmetrically embedded inside the frame 8. The conical groove 44 is located at the bottom of the dust collection groove 43. The air extraction groove 45 is symmetrically arranged on the frame 8. The connecting pipe 46 is embedded inside the frame 8, and one end of the connecting pipe 46 is connected to the air extraction groove 45, while the other end of the connecting pipe 46 is connected to the telescopic flexible hose 42. The air extraction heads 47 are arrayed on the air extraction groove 45, and one end of the air extraction head 47 extends into the dust collection groove 43. The filter screen 48 is located on one side of the air extraction head 47. The workbench 1 is symmetrically provided with discharge grooves 56, and the top of the discharge groove 56 is connected to the bottom of the conical groove 44.

[0053] When the exhaust fan 38 operates to extract air from the connecting groove 41, it can extract air from the extraction groove 45 through the cooperation of the telescopic hose 42 and the connecting pipe 46. Then, the exhaust head 47 can extract air from the dust collection groove 43, which will generate suction in the dust collection groove 43. After the outside air flows into the dust collection groove 43, it will flow towards the exhaust head 47. Impurities can be filtered and intercepted through the filter screen 48. The filtered and intercepted impurities will fall into the conical groove 44. The collected debris and impurities can flow into the discharge groove 56 through the conical groove 44. The debris can then flow into the collection mechanism for storage, thus achieving the purpose of collecting the debris generated by grinding and polishing.

[0054] Furthermore, a controller 2 is provided on the side of the workbench 1, and the limiting mechanism includes a support plate 3, a support block 4, a second push rod 5, a square block 6, and a rotating roller 7.

[0055] The controller 2 is electrically connected to the electronic components on the integrated polishing and grinding device for automotive trim parts, and can control the operation of the integrated polishing and grinding device for automotive trim parts. The worktable 1 provides installation space for the support plate 3. The support plate 3 can support the automotive trim parts to be polished. After the automotive trim parts are moved to the polishing location, the section of the automotive trim parts that has not entered the polishing area will be located on one side of the square block 6. By controlling the operation of the second push rod 5, the square block 6 will be pushed to move. When the square block 6 moves, it will drive the rotating roller 7 to move. The rotating roller 7 moves and contacts the surface of the automotive trim parts, thereby positioning the automotive trim parts.

[0056] Furthermore, a permanent magnet block 13 is fixedly embedded inside the grinding wheel 12, and a mounting plate 14 corresponding to the grinding wheel 12 is symmetrically arranged inside the mounting bracket 11. A cylinder 15 is symmetrically arranged inside the mounting plate 14, and a magnetic block 16 is slidably arranged inside the cylinder 15.

[0057] When the grinding wheel 12 rotates, it drives the permanent magnet block 13 to rotate. After the permanent magnet block 13 moves directly above the magnetic block 16, it attracts the magnetic block 16 to move. The movement of the magnetic block 16 drives the connecting rod 18 and the striking block 20 to move. The striking block 20 squeezes the return spring 19. After the grinding wheel 12 continues to rotate and moves away from above the magnetic block 16, the return spring 19 returns to its original position and pushes the striking block 20 to its original position. The return of the striking block 20 and its contact with the magnetic block 16 will cause the mounting bracket 11 to vibrate slightly, thereby vibrating and removing the impurities adsorbed on the mounting bracket 11. At the same time, the vibration can be transmitted to the automotive trim parts through the positioning mechanism, causing the automotive trim parts to vibrate slightly, which can remove the impurities adsorbed on the automotive trim parts and improve the cleanliness of the automotive trim parts.

[0059] The strip frame 25 provides installation space for the rotating wheel 37 through the annular groove 36. The dual-output shaft motor 23 drives the first drive wheel 24 to rotate. The rotation of the first drive wheel 24 drives the rotating wheel 37 to rotate through the belt, and then drives the exhaust fan 38 to move through the transmission wheel 39.

[0060] Furthermore, the polishing assembly includes a frame 26, a rotating shaft 27, a polishing belt 28, a second drive wheel 29, and a driven component. The frame 26 is embedded inside the mounting frame 11.

Adjacent second drive wheels 29 are connected by belt drive. The driven component for driving the second drive wheel 29 to rotate is disposed on the frame 26.

[0061] The rotation of pulley 22 drives the driven component to move via the belt. The movement of the driven component drives the second drive wheel 29 to rotate. When the second drive wheel 29 rotates, it drives the rotating shaft 27 to move. The rotation of the rotating shaft 27 causes the polishing belt 28 to move, and the polishing belt 28 can then polish the automotive trim parts.

[0062] Furthermore, the driven assembly includes a support shaft 30, a worm gear 31, a worm 32, a transmission rod 33, and a third drive wheel 34. The support shaft 30 is rotatably disposed inside the frame 26, and one end of the support shaft 30 is fixedly connected to the center position of the corresponding second drive wheel 29.

The center of the third drive wheel 34 is fixedly connected to one end of the transmission rod 33. The third drive wheel 34 is connected to the pulley 22 via belt drive. When the pulley 22 rotates, it will drive the third drive wheel 34 to rotate. When the third drive wheel 34 rotates, it will drive the worm 32 to rotate via the transmission rod 33. The rotation of the worm 32 will drive the worm wheel 31 to rotate. When the worm wheel 31 rotates, it will drive the second drive wheel 29 to rotate. The adjacent second drive wheels 29 are connected via belt drive, which will drive the other second drive wheels 29 to rotate synchronously.

[0063] Furthermore, the storage mechanism includes a support frame 59, a power motor 57, a conveyor roller 58, a collection groove 49, a slide 50, and a storage slot 51. The collection groove 49 is disposed inside the workbench 1, the support frame 59 is symmetrically disposed inside the collection groove 49, the power motor 57 is embedded inside the workbench 1, the conveyor rollers 58 are arranged in an array and rotate on the support frame 59, and one end of each adjacent conveyor roller 58 is provided with a wheel body and connected by belt drive. The output end of the power motor 57 is fixedly connected to one of the conveyor rollers 58 through a shaft. The slide 50 is disposed at the bottom of the workbench 1 and is connected to the collection groove 49. The collection groove 49 is conical in shape, and the storage slot 51 passes through the slide 50.

[0064] The collection trough 49 supports the conveyor roller 58 via the support frame 59. When the power motor 57 is working, it drives the conveyor roller 58 to rotate. The rotation of the conveyor roller 58 can assist in the movement of the car trim parts supported on the top, and can assist in the grinding and polishing of the car trim parts. During the grinding and polishing process, the debris falls downwards into the collection trough 49. The collection trough 49 is conical, which allows the debris to flow into the storage trough 51 for collection and storage.

[0065] Furthermore, the positioning mechanism includes a third push rod 35 and a positioning block 55. The third push rod 35 is fixedly installed inside the mounting bracket 11, and the positioning block 55 is installed on one side of the grinding wheel 12. One end of the third push rod 35 is fixedly connected to the positioning block 55.

[0066] When the positioning mechanism grinds and polishes the automotive trim, the operation of the third push rod 35 will push the positioning block 55 to move. After the positioning block 55 moves and contacts the top of the automotive trim, it will position the automotive trim, thus facilitating the grinding and polishing of the automotive trim. At the same time, when the mounting bracket 11 generates slight vibration, the third push rod 35 and the positioning block 55 work together to transmit the vibration to the automotive trim, thereby causing the automotive trim to vibrate. This can clean the automotive trim, prevent impurities from adhering to the automotive trim, and improve the grinding quality of the automotive trim.

[0067] Working principle: First, when polishing and grinding automotive trim parts using the integrated polishing and grinding device, the manual operator picks up the trim part to be polished and places it on the support plate 3. The trim part is then moved until it is below the grinding wheel 12. The dual-shaft motor 23 then drives the pulley 22 to rotate, which in turn drives the grinding wheel 12. Through the movement of the limiting mechanism, the position of the trim part is positioned. Simultaneously, the first push rod 9 pushes the mounting bracket 11 to move. As the mounting bracket 11 moves, it adjusts the position of the grinding wheel 12, causing it to move downwards and contact the surface of the trim part. The grinding wheel 12 then grinds the trim part. The rotation of the grinding wheel 12, through centrifugal force... The function causes grinding debris to flow into the dust collection trough 43. When the dual-shaft motor 23 is working, it drives the first drive wheel 24 to rotate, which in turn drives the rotating wheel 37 to rotate. The rotating wheel 37 is connected to the transmission wheel 39 via a belt drive, which drives the transmission wheel 39 to rotate synchronously. When the transmission wheel 39 rotates, it drives the exhaust fan 38 to move, which draws air from the connecting groove 41 through the exhaust pipe 40. The air inside the exhaust groove 45 can be drawn through the telescopic hose 42 and the connecting pipe 46. Then, the exhaust head 47 can draw air from the dust collection trough 43, which will generate suction in the dust collection trough 43. After the outside air flows into the dust collection trough 43, it will flow towards the exhaust head 47 and filter out impurities through the filter screen 48. The filtered impurities fall into the conical groove 44, allowing the collected debris to flow into the discharge groove 56. The discharge groove 56 then allows the debris to flow into the storage mechanism for storage. After polishing one side of the automotive trim piece, the trim piece is moved further, moving the polishing area below the polishing assembly. The first push rod 9 then adjusts the positions of the polishing wheel 12 and the polishing assembly, ensuring they contact the trim piece. The polishing wheel 12 continues to polish the trim piece. The rotation of the pulley 22, via the belt, drives the driven assembly, which in turn drives the second drive wheel 29. The rotation of the second drive wheel 29 drives the rotating shaft 27. When the grinding wheel 12 is in motion, the polishing belt 28 can move, thus polishing the automotive trim parts. The third push rod 35 moves the positioning block 55. After the positioning block 55 contacts the top of the automotive trim part, it positions the trim part. The rotation of the grinding wheel 12 drives the permanent magnet 13 to rotate. After the permanent magnet 13 moves directly above the magnetic block 16, it attracts the magnetic block 16. The movement of the magnetic block 16 drives the connecting rod 18 and the striking block 20 to move. The striking block 20 compresses the return spring 19. As the grinding wheel 12 continues to rotate and moves away from above the magnetic block 16, the return spring 19 returns to its original position, pushing the striking block 20 to its original position. The striking block 20 then contacts and collides with the magnetic block 16, causing a slight vibration in the mounting bracket 11.When the mounting bracket 11 vibrates slightly, the vibration is transmitted to the automotive trim parts through the cooperation of the third push rod 35 and the positioning block 55. This vibration cleans the trim parts, preventing impurities from adhering to them and improving the polishing quality. During polishing, most of the debris is collected by the collection mechanism. The debris falls downwards into the collection trough 49, which is cone-shaped, allowing the debris to flow into the storage trough 51 for collection and storage, maintaining the cleanliness of the work area.
