Description

Technical Field

[0001] This utility model relates to the field of wheel hub polishing technology, and in particular to an automotive wheel hub polishing device. Background Technology

[0002] Wheel rims, also known as wheel hubs, undergo different surface treatment processes depending on the characteristics and requirements of different car models. These can be broadly categorized into two types: painted and electroplated. For ordinary car models, aesthetics are less of a concern; good heat dissipation is a basic requirement. The process primarily uses painted rims, which involves spraying the paint and then electroplating it. This method is relatively economical, produces vibrant colors, and maintains the color for a long time; even after the vehicle is scrapped, the wheel rim color remains unchanged. Many Volkswagen models use painted rims for their wheel surface treatment.

[0003] After prolonged use, car wheel rims are prone to oxidation and become worn, requiring polishing to remove the oxides. Traditionally, wheel rim polishing involves fixing the rim in place and using a handheld polishing machine. This method is inefficient, and the polishing equipment is limited by the narrow edges and larger center of the rim. While smaller polishing tools can handle the narrower areas, the overall polishing efficiency is poor. Conversely, larger polishing tools are inconvenient for the narrower areas. Utility Model Content

This method is inefficient, and the polishing equipment is inconvenient for the narrower parts of the wheel hub and the larger parts in the middle. Therefore, if a smaller polishing tool is used, it can be used to polish the narrower parts, but the overall polishing efficiency will be poor.

[0026] Reference Figure 1-5A car wheel hub polishing device includes an operating table 1. A vertical rod 2 is fixedly mounted on the surface of the operating table 1. An installation arm 4 is slidably connected to the surface of the vertical rod 2. A connecting column 12 rotatably passes through the surface of the installation arm 4. A connecting arm 14 slidably passes through the surface of the connecting column 12. A polishing mechanism is provided on the surface of the connecting arm 14. A dust collection mechanism is provided on the surface of the connecting column 12. A drive mechanism for driving the connecting column 12 to rotate is provided on the surface of the installation arm 4. A triangular chuck 5 is fixedly mounted on the surface of the operating table 1 to fix the wheel hub and make the wheel hub and the connecting column 12 concentric. In use, the wheel hub is fixedly installed using the triangular chuck 5. Then, the installation arm 4 is moved down and the connecting arm 14 slides on the connecting column 12, so that the polishing mechanism can contact the position of the wheel hub to be polished. Then, the drive mechanism drives the connecting column 12 to rotate, and the connecting column 12 drives the connecting arm 14 to rotate synchronously. The connecting arm 14 drives the polishing mechanism to rotate, thereby polishing the wheel hub using the polishing mechanism. At the same time, the dust collection mechanism performs a dust collection operation on the polishing position to reduce dust pollution.

[0027] Furthermore, a vertical groove is formed on the surface of the upright post 2, and the mounting arm 4 is slidably connected inside the vertical groove. A first electric telescopic rod 3 is fixedly installed on the top of the upright post 2, and the output end of the first electric telescopic rod 3 is fixedly connected to the mounting arm 4. A second electric telescopic rod 13 is fixedly installed on the side wall of the connecting column 12, and the output end of the second electric telescopic rod 13 is fixedly connected to the connecting arm 14. The mounting arm 4 slides in the vertical groove of the upright post 2 and is controlled to rise and fall by the first electric telescopic rod 3. The connecting arm 14 slides on the connecting column 12 and is controlled to slide by the second electric telescopic rod 13. This facilitates the contact between the polishing mechanism and the wheel hub surface during adjustment, and adapts to wheel hubs of different sizes.

[0028] Furthermore, the drive mechanism includes a first motor 7, which is fixedly mounted on the surface of the mounting arm 4. A drive gear 6 is fixedly mounted on the output port of the first motor 7, and a driven gear 10 is fixedly mounted on the surface of the connecting column 12. The drive gear 6 and the driven gear 10 mesh. In use, when the drive mechanism is started, the first motor 7 drives the drive gear 6 to rotate, the drive gear 6 drives the driven gear 10 to rotate, and the driven gear 10 drives the connecting column 12 to rotate.

[0029] Furthermore, the vacuuming mechanism includes a vacuum hose 11 and a vacuum cleaner 25. The vacuum hose 11 is fixedly connected to the connecting post 12. The surface of the connecting arm 14 has an elongated hole for the vacuum hose 11 to pass through. The vacuum hose 11 is configured with an "L" shape. A movable tube 15 is slidably fitted onto the surface of the vacuum hose 11. A vacuum hood is provided at the end of the movable tube 15, facing the polishing mechanism. A bracket 9 is fixedly mounted on the surface of the mounting arm 4. A threaded tube 8 is fixedly mounted on the surface of the bracket 9. The bottom end of the threaded tube 8 is rotatably connected to the vacuum hose 11. A fixing rod 16 is fixedly mounted on the surface of the movable tube 15. The top end of the fixing rod 16 is fixedly connected to the connecting arm 14. The vacuum cleaner 25 is fixedly mounted on the surface of the connecting arm 14. The air inlet end of the vacuum cleaner 25 is connected to a flexible hose. The vacuuming mechanism is connected to the threaded tube 8. When the vacuum cleaner 25 is activated, it uses the hose, threaded tube 8, vacuum tube 11, and moving tube 15 to vacuum the polished area. The threaded tube 8 is mounted on the mounting arm 4 by the bracket 9, so the threaded tube 8 remains fixed. The vacuum tube 11 is mounted on the connecting column 12, and the vacuum tube 11 and the threaded tube 8 are rotatably connected. Therefore, the vacuum tube 11 rotates with the connecting column 12, so that the vacuum cover can rotate with the polishing mechanism. Moreover, the moving tube 15 is connected to the connecting arm 14 through the fixed rod 16. Therefore, even if the connecting arm 14 moves on the connecting column 12, the moving tube 15 can move synchronously, so that the relative position between the vacuum cover and the polishing mechanism can be kept stable.

[0030] Furthermore, the polishing mechanism includes a second motor 17, which is fixedly mounted on the top of the connecting arm 14. A polishing rod 20 is fixedly mounted on the output shaft port of the second motor 17. A polishing block 22 is sleeved on the surface of the polishing rod 20. An annular groove 23 is formed on the top of the polishing block 22. A connecting ring 21 is rotatably connected inside the annular groove 23. A screw 18 is fixedly mounted on the top of the connecting ring 21. The screw 18 passes through the connecting arm 14, and a nut 19 is threaded onto the surface of the screw 18. During use, when polishing a small area or a small edge is required, the nut 19 can be manually rotated to make the screw 18 drive the connecting ring 21 to move upward. The connecting ring 21 will drive the polishing block 22 to move upward synchronously, thereby moving the polishing block 22 away from the bottom of the polishing rod 20. At this time, the second motor 17 is started, and the second motor 17 drives the polishing rod 20 to move upward. The first motor 7 rotates 0, allowing for polishing of small areas or edges on the wheel hub. Starting the first motor 7 enables polishing of the same location on the entire circumference of the wheel hub. For polishing larger areas, the screw 18, connecting ring 21, and polishing block 22 can be moved downwards by rotating the nut 19, aligning the bottom of the polishing block 22 with the bottom of the polishing rod 20. This allows the polishing block 22 and polishing rod 20 to polish the wheel hub simultaneously. When the second motor 17 drives the polishing rod 20 to rotate, the polishing block 22 and polishing rod 20 are slidably connected, allowing them to rotate synchronously. The connecting ring 21 and polishing block 22 are rotatably connected, so they do not affect the rotation of the polishing block 22. The connecting ring 21, screw 18, and nut 19 only serve to move and fix the polishing block 22 in place.

[0031] Furthermore, a groove 24 is provided on the surface of the polishing rod 20, and the polishing block 22 is slidably connected to the polishing rod 20 through the groove 24. After the polishing block 22 moves down to the lowest point, its bottom is flush with the bottom of the polishing rod 20.

[0032] In summary, during use, the wheel hub is fixedly installed using the triangular chuck 5. Then, the mounting arm 4 is lowered, and the connecting arm 14 slides on the connecting column 12, allowing the polishing mechanism to contact the area of ​​the wheel hub to be polished. The driving mechanism then drives the connecting column 12 to rotate, which in turn drives the connecting arm 14 to rotate synchronously. The connecting arm 14 then drives the polishing mechanism to rotate, thus polishing the wheel hub. Simultaneously, a dust extraction mechanism is used to vacuum the polishing area, reducing dust pollution. The mounting arm 4 slides in the vertical groove of the upright 2, and its lifting and lowering are controlled by the first electric telescopic rod 3. The connecting arm 14 slides on the connecting column 12, and its sliding is controlled by the second electric telescopic rod 13, facilitating polishing during this adjustment. The mechanism contacts the wheel hub surface, adapting to wheel hubs of different sizes. During operation, the drive mechanism activates the first motor 7, which drives the driving gear 6 to rotate. The driving gear 6 then drives the driven gear 10, which in turn drives the connecting column 12 to rotate. During operation, the vacuum cleaner 25 activates, utilizing the hose, threaded tube 8, suction pipe 11, and moving tube 15 to vacuum the polished area. The threaded tube 8 is mounted on the mounting arm 4 using a bracket 9, thus keeping it fixed. The suction pipe 11 is mounted on the connecting column 12, and the suction pipe 11 and threaded tube 8 are rotatably connected, allowing the suction pipe 11 to rotate with the connecting column 12. This allows the vacuum cover to rotate with the polishing mechanism. Furthermore, the moving tube 15 is connected to the connecting arm 14 via the fixed rod 16. Therefore, even if the connecting arm 14 moves on the connecting post 12, the moving tube 15 can move synchronously, thus maintaining a stable relative position between the dust collection hood and the polishing mechanism. During use, when polishing small areas or edges, the nut 19 can be manually rotated to move the screw 18 upwards, causing the connecting ring 21 to move upwards. The connecting ring 21 then moves the polishing block 22 upwards, moving it away from the bottom of the polishing rod 20. At this point, the second motor 17 is activated, rotating the polishing rod 20 to polish small areas or edges on the hub. Activating the first motor 7 allows for the polishing of... Polishing is performed on the same position on the entire circumference of the wheel hub. If polishing is required on a larger area of ​​the wheel hub, the screw 18, connecting ring 21, and polishing block 22 can be moved down by rotating nut 19, so that the bottom of polishing block 22 is flush with the bottom of polishing rod 20. Thus, polishing block 22 and polishing rod 20 can polish the wheel hub simultaneously. When the second motor 17 drives polishing rod 20 to rotate, the polishing block 22 and polishing rod 20 are slidably connected, so they can rotate synchronously. The connecting ring 21 and polishing block 22 are rotatably connected, so they will not affect the rotation of polishing block 22. The connecting ring 21, screw 18, and nut 19 only serve to move and fix the position of polishing block 22.
