Description

Technical Field

[0001] The utility model belongs to the technical field of wheel hub processing, and in particular relates to a polishing device for an automobile aluminum alloy wheel hub. Background Art

[0002] At present, common car wheels include steel wheels and aluminum alloy wheels. Steel wheels have high strength and are often used in large trucks, but steel wheels are heavy and have a single appearance. They do not conform to today's low-carbon and fashionable concepts and are gradually being replaced by aluminum alloy wheels.

[0003] In the production process of automobile aluminum alloy wheels, the wheels need to be polished. In the existing polishing process, the clamped wheels are usually sent into a polishing box filled with polishing media such as magnetic powder, and the vibration of the polishing box drives the friction between the polishing media and the wheel to achieve polishing. However, in actual applications, this polishing method can only clamp and polish one wheel at a time, the overall polishing efficiency is low, and it is not convenient to quickly discharge and replace the polishing media after a period of use, which is not conducive to subsequent operations and needs to be improved.

[0024] When polishing the wheel hub 30, multiple wheel hubs 30 can be clamped and fixed at one time through multiple sets of clamps 15 on the support column 11. Then, the hydraulic cylinder 9 is operated to extend its piston rod, which can drive the second motor 10 and the support column 11 to move downward as a whole until the wheel hub 30 is completely sunk into the polishing tank 7. Next, the vibrator 8 is operated to drive the entire polishing tank 7 to vibrate, which can drive the polishing medium in the polishing tank 7 to rub against the wheel hub 30, so as to achieve the purpose of clamping and polishing multiple wheel hubs 30 at one time, and ensure the overall polishing efficiency. At the same time, the second motor 10 and each third motor 14 are operated. The operation of the second motor 14 can drive the support column 11 and the multiple hubs 30 clamped thereon to revolve as a whole. The operation of each third motor 14 can drive the corresponding fixture 15 and the hub 30 clamped on the corresponding fixture 15 to rotate independently. Therefore, the friction effect between the hub 30 and the polishing medium can be enhanced through the revolution and rotation of the hub 30, so that the two can contact and rub more fully and evenly, thereby more effectively improving the overall efficiency and quality of polishing.

Then, the second electric push rod 21 is operated to extend its telescopic end and extend out of the support rod 16 through the corresponding moving groove 22. Next, the corresponding first electric push rod 19 is operated to shrink its telescopic end, driving the entire lifting plate 20 to descend, and the telescopic end of the corresponding second electric push rod 21 can be driven to move down along the corresponding moving groove 22 in the corresponding moving groove 22, until the telescopic end of the second electric push rod 21 is pressed against the wheel hub 30, and the wheel hub 20 is pressed against the limiting plate 17, so that the clamping and fixing of the wheel hub 30 can be completed, and the clamping is more stable and reliable, so as to ensure that the wheel hub 30 rotates synchronously with the whole of the fixture 15 during subsequent polishing, so as to cooperate to achieve efficient and high-quality polishing operations. After the polishing is completed, the first electric push rod 19 is operated first to extend its telescopic end, driving the lifting plate 20 to rise, and then the second electric push rod 21 is operated to shrink its telescopic end into the cavity 18, so that the limit of the wheel hub 30 can be released, and then the wheel hub 30 can be removed from the support rod 16. In this way, the wheel hub 30 can be quickly assembled and disassembled, the operation is simple and convenient, and it is more conducive to improving the overall polishing efficiency, reducing the difficulty of the operation, and being more practical.
