Technical Field

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

[0002] Alloy wheels are a type of car wheel hub, made of alloy materials, usually aluminum alloy. Compared with traditional steel wheels, alloy wheels are lighter, stronger, more attractive, and can provide better heat dissipation. Alloy wheels can also improve the car's handling performance and fuel economy. The process of manufacturing alloy wheels usually includes the following steps: alloy melting, wheel casting, precision machining, heat treatment, surface treatment, quality inspection and packaging.

[0003] The surface treatment of alloy wheels is to treat the wheels, including spraying, anodizing, electroplating, etc., to improve its surface finish, corrosion resistance and aesthetics, including polishing and other steps.

When one side is polished, the motor drives the clamping ring, connecting plate and telescopic rod to rotate to change the side. Repeat the above work to achieve the polishing work of the other side of the wheel hub, and realize fast switching;

[0018] In summary, the present invention clamps the wheel hub by setting up a clamping mechanism, thereby ensuring the stability of the wheel hub during the polishing process.

When the polishing of one side is completed, the motor 2 15 drives the rotating rod 16, motor 3 17 and polishing sheet 18 to rotate to the outside of the ring 4 so that it does not affect the rotation of the clamping ring 6. At this time, the motor 1 5 drives the clamping ring 6, connecting plate 9 and telescopic rod 8 to rotate to change the surface, and repeat the above work to achieve the polishing of the other side of the hub 7.

[0025] A clamping mechanism is provided in the clamping ring 6, and the clamping mechanism includes a connecting plate 9 fixedly connected to the upper side wall of the clamping ring 6, a telescopic rod 8 is fixed to the lower side wall of the connecting plate 9, and two symmetrically arranged moving rods 10 are slidably inserted on the outer wall of the clamping ring 6 at the junction of the outer wall of the telescopic rod 8 and the inner wall of the circular ring 4. One end of the moving rod 10 located in the clamping ring 6 is fixedly connected to an arc-shaped clamping plate 12, and a telescopic spring 11 is sleeved on the outer wall of the other end of the moving rod 10, and the two ends of the telescopic spring 11 are respectively fixedly connected to the outer wall of the moving rod 10 and the outer wall of the clamping ring 6. Two symmetrically arranged adjusting plates 14 are fixedly connected to the outer wall of the driving end of the telescopic rod 8, and the ends of the two adjusting plates 14 are respectively located on the outer side of the end of one of the moving rods 10, and the end of the adjusting plate 14 is fixedly connected The right-angled trapezoidal plate 13 is located on the outer side of the end of the moving rod 10, and the end of the moving rod 10 contacts the inclined surface of the right-angled trapezoidal plate 13. The end of the moving rod 10 that contacts the inclined surface of the right-angled trapezoidal plate 13 is set in a semicircular shape, and the wheel hub 7 is placed between the two arc-shaped clamping plates 12. The driving end of the telescopic rod 8 is retracted, and the cross-sectional thickness of the right-angled trapezoidal plate 13 in contact with the moving rod 10 gradually increases. Therefore, in order to adapt to the movement of the right-angled trapezoidal plate 13, the moving rod 10 will synchronously move into the clamping ring 6, pushing the two arc-shaped clamping plates 12 to move inward together, contacting and pressing against the wheel hub 7, and completing the fixation of the wheel hub 7. Similarly, when the driving end of the telescopic rod 8 is retracted, the moving rod 10 and the arc-shaped clamping plate 12 will move outward under the reverse elastic force of the telescopic spring 11, ending the clamping of the wheel hub 7.

The carbon brush is connected to the motor 5, and the conductive ring is connected to an external power source. The carbon brush is connected to the conductive ring to realize the power supply of the external power source to the motor 5, ensuring that the motor 20 can still be connected to the external power source after driving the motor 5 to rotate, and then the motor 5 drives the clamping ring 6 to rotate to perform the turning work;

[0027] A motor 2 15 is fixedly connected to the outer wall of one of the support rods 3, a rotating rod 16 is fixedly connected to the driving end of the motor 2 15, a motor 3 17 is fixedly connected to the end of the rotating rod 16, and a polishing sheet 18 is fixedly connected vertically downward to the driving end of the motor 3 17. The polishing sheet 18 is driven to rotate by starting the motor 3 17, and the surface polishing of the wheel hub 7 can be completed through the contact between the polishing sheet 18 and the wheel hub 7.

[0028] A water tank 19 is fixedly connected to the outer wall of the rotating rod 16, and a liquid pump is arranged in the water tank 19. The output end of the liquid pump is fixedly connected to a drain pipe. The end of the drain pipe extends through the outside of the water tank 19 and is equipped with a nozzle. The nozzle is arranged toward the edge of the polishing sheet 18. The end of the drain pipe close to the polishing sheet 18 is bent, and the nozzle is inclined toward the edge of the polishing sheet 18. During the polishing process, the liquid pump pumps cooling water to the nozzle and sprays it out, contacting the polishing sheet 18 and the wheel hub 7. On the one hand, the cooling of the polished wheel hub 7 is achieved. On the other hand, the pumped cooling water can contact and absorb the waste chips generated by polishing, and fall down into the annular groove 22 for collection, thereby avoiding the waste chips from flying up and causing pollution to the surrounding environment.

[0029] The upper surface of the connecting seat 2 is provided with an annular groove 22 located on the outside of the motor 20, and a collecting groove 23 is inserted on the outer wall of the connecting seat 2.

Subsequently, the clean water can be pumped out for reciprocating use, and then the collecting groove 23 can be pulled out to clean the waste chips.

[0030] In summary, the polishing process of the wheel hub 7 includes:

[0031] The wheel hub 7 is placed between the two arc-shaped clamping plates 12, the driving end of the telescopic rod 8 is retracted, and the right-angled trapezoidal plate 13 squeezes the moving rod 10 to move inside the clamping ring 6, pushing the two arc-shaped clamping plates 12 to move inside together, contacting and pressing against the wheel hub 7, and completing the fixing of the wheel hub 7;

[0032] The motor 2 15 drives the rotating rod 16, the motor 3 17 and the polishing sheet 18 to rotate to the upper side of the ring 4 so that the polishing sheet 18 contacts the wheel hub 7, and the motor 3 17 is started to drive the polishing sheet 18 to rotate to polish the wheel hub 7. The motor 20 drives the fixing rod 21, the motor 1 5, the clamping ring 6, the wheel hub 7 and the telescopic rod 8 to rotate, so that the polishing sheet 18 can complete the polishing work of the edge of the entire wheel hub 7;

[0033] During the polishing process, the liquid pump pumps the cooling water out to the nozzle and sprays it out, contacting the polishing sheet 18 and the hub 7. On the one hand, the hub 7 after polishing is cooled. On the other hand, the pumped cooling water can contact and absorb the waste chips generated by polishing, and fall down into the annular groove 22 for collection, thereby preventing the waste chips from flying.

[0034] After polishing of one side of the wheel hub 7 is completed, the motor 2 15 drives the rotating rod 16, the motor 3 17 and the polishing sheet 18 to rotate to the outside of the ring 4 so that they do not affect the rotation of the clamping ring 6. At this time, the motor 1 5 drives the clamping ring 6, the connecting plate 9 and the telescopic rod 8 to rotate to change the surface. The motor 2 15 drives the rotating rod 16, the motor 3 17 and the polishing sheet 18 to rotate to the upper side of the ring 4 so that the polishing sheet 18 contacts the wheel hub 7, and the polishing work on the other side continues.

[0035] The cooling water that absorbs the waste chips falls down into the annular groove 22 for collection, and the waste chips slide along the inner bottom wall of the annular groove 22 to the collecting groove 23 for collection. Subsequently, the clean water can be pumped out for reciprocating use, and then the collecting groove 23 can be pulled out to clean the waste chips.
