[0002] The appearance of the wheel rim directly affects the overall visual appeal of the wheel. The wheel rim manufacturing process involves dozens of steps, and scratches, dents, and other imperfections are inevitable on the surface. Traditional methods involve manual grinding and polishing, which is not only inefficient but also leaves some minor imperfections on the manually polished surface, leading to repeated rework and wasted costs. Therefore, there is an urgent need to develop an automated, high-quality water polishing device for steel wheel surfaces. Utility Model Content
[0003] The purpose of this invention is to provide a wheel hub polishing device with good polishing effect.
[0004] To achieve the above objectives, this utility model proposes a wheel hub polishing device, which includes a polishing tank, a clamping mechanism, and a lifting mechanism. The polishing tank contains polishing liquid, and a stirrer is installed inside the polishing tank. The clamping mechanism includes a swing arm, a clamp, and a rotating part. The clamp is located at the first end of the swing arm and is used to clamp the wheel hub. The rotating part is used to drive the clamp and the wheel hub to rotate. The lifting mechanism is connected to the second end of the swing arm. The middle section of the swing arm is rotatably connected to a swing support. The lifting mechanism drives the second end of the swing arm to rise or fall, thereby controlling the first end of the swing arm to rise or fall. The first end of the swing arm is located directly above the polishing tank.
[0005] Preferably, the second end of the swing arm is also provided with a motor, and the rotating part is located at the first end of the swing arm. The motor and the rotating part are connected by a rotating shaft. The swing arm has a hollow structure, and the rotating shaft passes through the swing arm to realize the motor driving the rotating part to rotate.
[0006] Preferably, the swing support includes a support part and a base, one end of the support part is fixedly connected to the swing arm, and the other end of the support part is rotatably connected to the base.
[0007] Preferably, the support part is inverted "L" shape, the horizontally extended part of the support part is fixedly connected to the swing arm, and the vertically extended part of the support part is pinned to the base.
[0008] Preferably, the swing support and the lifting mechanism are vertically arranged on one side of the polishing tank in the horizontal direction, and the clamping mechanism is horizontally placed above the polishing tank.
[0009] The beneficial effects of this utility model are as follows:
[0010] (1) In this application, a swing arm clamping mechanism is used to clamp the wheel hub. The automatic operation of lowering the wheel hub into the polishing pool or raising it out of the polishing pool can be quickly realized by swinging the clamping mechanism. The polishing pool, together with the clamping mechanism and the lifting mechanism, realizes the automatic polishing of the wheel hub. Polishing can be completed in only 80-120 seconds, which greatly improves the polishing efficiency of the wheel hub.
[0011] (2) By setting up a stirrer in the polishing tank to agitate the polishing liquid and the rotating part to drive the wheel hub to rotate, the wheel hub after water polishing not only eliminates the small imperfections left by manual polishing, but also solves the problems of polishing dead corners and abrasive waste in existing polishing machines, thus improving polishing efficiency. Attached Figure Description
[0012] Figure 1 This is a schematic diagram of a wheel hub polishing device in a preferred embodiment of the present invention. Detailed Implementation
[0013] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.
[0014] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0015] See Figure 1 As shown in the preferred embodiment of this utility model, this embodiment proposes a wheel hub polishing device, which includes a polishing pool 11, a clamping mechanism 2, and a lifting mechanism 3. The clamping mechanism 2 includes a swing arm 21, a clamp 23, and a rotating part 22. The clamp 23 and the rotating part 22 are disposed at the first end of the swing arm 21. The clamp 23 is used to clamp the wheel hub 101, and the rotating part 22 is used to drive the clamp 23 and the wheel hub 101 to rotate. The lifting mechanism 3 is connected to the second end of the swing arm 21. The middle section of the swing arm 21 is rotatably connected to a swing support 4. The lifting mechanism 3 drives the second end of the swing arm 21 to rise or fall, thereby controlling the first end of the swing arm 21 to rise or fall. The first end of the swing arm 21 is located directly above the polishing pool 11. When the lifting mechanism 3 drives the second end of the swing arm 21 to rise, the first end of the swing arm 21 falls to allow the wheel hub 101 clamped at the first end of the swing arm 21 to fall into the polishing pool 11.
[0016] The polishing tank 11 has an upward opening in the vertical direction. Polishing liquid 13 is contained within the polishing tank 11. A stirrer 12 is installed inside the polishing tank 11. The wheel hub 101 is completely immersed in the polishing liquid 13. The rotating part 22 drives the wheel hub 101 to spin, which, combined with the stirring of the stirrer 12, agitates the polishing liquid 13, achieving efficient polishing of the wheel hub 101 and avoiding dead zones in the polishing process. The polishing liquid 13 is composed of coarse grinding fluid and coarse grinding stones at a mass ratio of 1:5.3. The coarse grinding fluid is model HQ-369, and the coarse grinding stones are model HQ-008ZY. This ratio of polishing liquid 13 improves the polishing effect. Furthermore, storing the polishing liquid 13 in the polishing tank 11 allows for reuse and reduces waste. Of course, in other embodiments, the polishing section 11 can also be configured as a box-shaped structure. The polishing section 11 with the box-shaped structure has an opening on one side in the horizontal direction, which is used to allow the hub 101 to extend into the polishing pool 11 to achieve polishing of the hub 101. However, with such a configuration, it is more difficult for the hub 101 to extend into the polishing pool 11, which will increase the manufacturing cost of the hub polishing machine. The mixer 12 can be set on the bottom wall or the side wall of the polishing pool 11, as long as it can agitate the polishing liquid 13 inside the polishing pool 11. In this embodiment, the mixer 12 is a rotating wheel with a rotation speed of 10 revolutions / min. In conjunction with the clamping mechanism 2, it drives the hub 101 to rotate at a speed of 15-30 revolutions / min, so that the hub 101 can be fully inserted into the polishing liquid 13 and polished in 80-120 seconds, thereby increasing the speed of hub polishing.
[0017] To enable the rotation of the rotating part 22, a motor 24 is provided at the second end of the swing arm 21. The motor 24 is connected to the rotating part 22 via a rotating shaft 25. In this embodiment, the swing arm 21 has a hollow structure, and the rotating shaft 25 passes through the inside of the swing arm 21. One end of the rotating shaft 25 is fixedly connected to the rotating part 22, and the other end of the rotating shaft 25 is fixedly connected to the motor 24, so that the motor 24 drives the rotating part 22 to rotate via the rotating shaft 25.
[0018] The swing support 4 includes a support part 41 and a base 42. The support part 41 and the base 42 are pinned together to allow the support part 41 to rotate. The support part 41 is inverted "L" shape. The laterally extended part of the support part 41 is fixedly connected to the swing arm 21 of the clamping mechanism 2, and the longitudinally extended part of the support part 41 is fixedly pinned to the base. The inverted "L" shape of the support part 41 increases the support surface of the support part 41, making the connection between the support part 41 and the swing arm 21 more stable and providing better support for the heavy clamping mechanism 2.
[0019] In this embodiment, the swing arm 21 is horizontally positioned directly above the polishing tank 11, and the swing support 4 and the lifting mechanism 3 are vertically positioned on one side of the polishing tank 11 in the horizontal direction, so that the entire polishing device structure is more compact. The wheel hub polishing device proposed in this embodiment also includes a bracket 5 for fixing the swing support 4 and the lifting mechanism 3 to realize the combination of the swing support 4 and the lifting mechanism 3.
[0020] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
