Description

Technical Field

[0001] This utility model relates to the field of wheel hub coating technology, specifically, to a wear-resistant and corrosion-resistant coating part for automobile wheel hubs. Background Technology

[0002] As a crucial exterior component of automobiles, the quality and finish of wheel rim coating directly impact the vehicle's market competitiveness. Furthermore, with increasing automobile production, higher demands are placed on the production efficiency and quality stability of wheel rim coating, driving continuous development and innovation in wheel rim coating technology. Automobile wheels are constantly exposed to the elements and are susceptible to corrosion from various factors. For example, impacts from gravel during driving can scratch the wheel rim surface, while rainwater, snowmelt, and oil stains can cause corrosion, reducing wheel rim performance and lifespan. Coating can form a protective film on the wheel rim surface, enhancing its wear resistance and corrosion resistance, preventing oxidation and rust, and extending its service life.

[0003] There are many existing technologies for wheel rim painting, such as:

[0004] According to Chinese patent application number CN202223596407.4, specifically, it is a tooling system for automotive painting processes, including a painting box and two doors. The doors are hinged to the front end of the painting box. Electric cylinders are fixed to the left and right ends of the inner wall of the painting box. The power ends of the electric cylinders are connected to concave frames. A rotating motor is fixed to the top of each concave frame, and a drive roller is connected to the power end of each rotating motor. The lower end of the drive roller is rotatably connected to the bottom end of the concave frame. Ball bearings are rotatably connected to the outer side of the bottom end of the concave frame. A spray can is fixed to the top of the painting box. This invention allows the car wheel hub to rotate freely through the rotation of the drive rollers. Combined with a reciprocating rotating assembly, it drives the first and second spray nozzles to rotate reciprocally, causing the second spray nozzles to move closer or further apart. Therefore, it facilitates the complete one-time painting of the exterior of the car wheel hub, reducing operational hassles and effectively improving painting efficiency.

[0005] The aforementioned technologies lack the cleaning and drying of wheel hubs before and after coating, which reduces the coating quality and efficiency of the wheel hubs. Furthermore, the coating equipment in traditional technologies is large in size and complex to operate, making it suitable for large factories and enterprises to produce a large number of wheel hubs. Private or small enterprises mostly use manual hand-held spray guns to coat wheel hubs, which is labor-intensive, time-consuming, and labor-intensive, resulting in low practicality of the coating equipment.

[0006] The purpose of this invention is to provide a wear-resistant and corrosion-resistant coating for automobile wheel hubs to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides a wear-resistant and corrosion-resistant coating part for automotive wheel hubs, including a coating box. An installation plate is provided at the upper end of the interior of the coating box. A clamping plate is symmetrically slidably connected inside the installation plate. A rotating column is rotatably connected inside the clamping plate. Telescopic rods are symmetrically fixedly connected to the outer side of the rotating column. A top plate is fixedly connected to the output end of the telescopic rods. A moving block is slidably connected inside the installation plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] By rotating the bidirectional threaded rod, the two clamping plates are driven to move, and the distance between the two clamping plates is adjusted. The top plate is pushed up and down by the telescopic rod, extending into the wheel hub to clamp it in the opposite direction. This allows the equipment to clamp and fix wheel hubs of different sizes. Then, the first motor drives the rotating column to rotate the wheel hub.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5As shown, this embodiment provides a wear-resistant and corrosion-resistant coating part for automobile wheel hubs, including a coating box 1. Considering that traditional coating equipment is large in size and complex to operate, suitable for large factories and enterprises to produce a large number of wheel hubs, while private or small enterprises mostly use manual hand-held spray guns to coat wheel hubs, which is labor-intensive, time-consuming and labor-intensive, the coating box 1 has a simple overall structure, small size, is easy to move and transport, has a low production cost, and is more convenient for private or small enterprises to use. In order to ensure that the equipment can coat wheel hubs of different sizes at a low cost and to improve the practicality of the equipment, a mounting plate 2 is provided at the upper end of the interior of the coating box 1. A clamping plate 21 is symmetrically slidably connected inside the mounting plate 2, and a rotating column 22 is rotatably connected inside the clamping plate 21. Telescopic rods 23 are symmetrically fixedly connected to the outside of the rotating column 22. The output end is fixedly connected to a top plate 24, which drives two clamping plates 21 to move. By adjusting the distance between the two clamping plates 21, the top plate 24 is pushed up and down by the telescopic rod 23, extending into the wheel hub to clamp the wheel hub in the opposite direction. This enables the equipment to clamp and fix wheel hubs of different sizes, increasing the applicability of the equipment. Considering that the equipment lacks cleaning and drying work for the wheel hub before and after coating, the coating quality and efficiency of the wheel hub are relatively low. Therefore, a moving block 3 is slidably connected inside the mounting plate 2. From left to right, a water spray head 31, a spray gun head 32, and an air jet head 33 are fixedly connected to the bottom of the moving block 3. By manually sliding the moving block 3, the water spray head 31, the spray gun head 32, and the air jet head 33 at the bottom of the moving block 3 are controlled to clean, coat, and dry different positions of the wheel hub, ensuring the coating quality of the wheel hub while improving work efficiency, reducing manual labor intensity, and improving coating accuracy.

[0027] The improvement in this embodiment lies in the following: by moving the two clamping plates 21, the distance between them is adjusted, and the top plate 24 is moved up and down by the telescopic rod 23, extending into the wheel hub to clamp it in the opposite direction. This allows the equipment to clamp and fix wheel hubs of different sizes. The rotating column 22 drives the wheel hub to rotate, and the moving block 3 is manually slidable, allowing the water spray head 31, spray gun head 32, and air jet head 33 at the bottom of the moving block 3 to clean, coat, and dry different positions on the wheel hub. This ensures the quality of the wheel hub coating while improving work efficiency. Furthermore, the overall structure is simple, compact, easy to move and transport, and has a low production cost, making it more convenient for private individuals or small businesses to use, thus improving the practicality of the coating equipment.

[0028] Specifically, considering that different positions of the wheel hub need to be coated during the coating process, an observation window 11 is provided on one side of the coating box 1 to facilitate manual movement of the coating components and opening and closing of the control components. This allows personnel to observe the position of components such as the spray gun head 32. A control panel 12 is fixedly connected to one side of the coating box 1. The control panel 12 controls the opening and closing of the first motor 26, the second motor 41, and the control valve on the outside of the connecting pipe 34, which facilitates manual coating operations.

[0029] Considering the need to paint different parts of the wheel hub, an anti-slip pad 25 is fixedly connected to one side of the top plate 24. One end of a rotating column 22 is fixedly connected to the output end of the first motor 26. The telescopic rod 23 pushes the top plate 24 to clamp the wheel hub in the opposite direction. At this time, the anti-slip pad 25 contacts the inner side of the wheel hub, increasing friction. Therefore, when the first motor 26 drives the rotating column 22 to rotate, the wheel hub can rotate with the top plate 24 and the anti-slip pad 25, facilitating subsequent painting work on the outer surface of the wheel hub. To improve the applicability of the painting equipment and enable clamping and fixing of wheel hubs of different sizes, A bidirectional threaded rod 27 is threaded to one end of the clamping plate 21, and a first guide rod 28 is slidably connected to the other end of the clamping plate 21. Both the bidirectional threaded rod 27 and the first guide rod 28 are fixedly connected to the top of the mounting plate 2 by a fixing block 29. By rotating the bidirectional threaded rod 27, the two clamping plates 21 are driven to move, and the distance between the two clamping plates 21 is adjusted to facilitate the fixing of hubs of different lengths. The first guide rod 28 guides the movement of the clamping plates 21, so that the clamping plates 21 can move stably left and right, avoiding affecting the clamping effect of the clamping plates 21.

[0030] Considering that the equipment needs to be connected to external components during use, connecting pipes 34 are fixedly connected to one end of the water spray head 31, spray gun head 32, and air jet head 33. The water spray head 31 is connected to an external water source through the connecting pipe 34, the spray gun head 32 is connected to an external paint storage mechanism through the connecting pipe 34, and the air jet head 33 is connected to an external air supply mechanism through the connecting pipe 34. Then, the control valve on the outside of the connecting pipe 34 is controlled by the control panel 12 to open and close, so that the water spray head 31, spray gun head 32, and air jet head 33 can clean, paint, and dry different parts of the wheel hub respectively. Before painting, the water spray head 31 and spray gun head 32 are used to clean and dry the wheel hub to ensure the cleanliness of the wheel hub and avoid impurities adhering to the outside of the wheel hub from affecting the quality of the wheel hub painting. After painting, the air jet head 33 is used to quickly dry the wheel hub, thereby improving the working efficiency of the equipment.

[0031] Considering that traditional painting processes can easily impact the external environment, to avoid pollution, a one-way threaded rod 4 is threadedly connected to one end of the mounting plate 2. The top of the one-way threaded rod 4 is fixedly connected to the output end of the second motor 41. A second guide rod 42 is slidably connected to the other end of the mounting plate 2. One end of the second guide rod 42 is fixedly connected to one side of the painting box 1. Before painting, the one-way threaded rod 4 is driven to rotate forward by the second motor 41, causing the mounting plate 2 to move upward. The hub is then manually clamped and fixed between the two clamping plates 21. Then, the second motor 41 drives the one-way threaded rod 4 to rotate in the opposite direction, causing the mounting plate 2 to move downward and engage with the top of the painting box 1, thus creating a relatively sealed environment inside the painting box 1 and reducing pollution to the external environment during the painting process.

[0032] In summary, the working principle of this solution is as follows:

[0033] First, before painting, the second motor 41 drives the one-way threaded rod 4 to rotate forward, causing the mounting plate 2 to move upward and the clamping plate 21 to move out of the painting box 1. Then, the wheel hub is manually clamped and fixed between the two clamping plates 21. The two-way threaded rod 27 is rotated to drive the clamping plate 21 to move, adjusting the distance between the two clamping plates 21 so that the clamping plate 21 can clamp and fix wheel hubs of different sizes. At this time, the rotating column 22 penetrates into the wheel hub, and the telescopic rod 23 pushes the top plate 24 to move and clamp the wheel hub in the opposite direction. The anti-slip pad 25 contacts the inner side of the wheel hub to increase friction. After installation, the second motor 41 drives the one-way threaded rod 4 to rotate in the opposite direction, and the mounting plate 2 moves downward and engages with the top of the painting box 1, creating a relatively sealed environment inside the painting box 1 and reducing pollution to the external environment during the painting process. The water spray head 31, spray gun head 32, and air jet head 33 are all connected to the external supply components through the top plate 24. Then, the first... A motor 26 drives the rotating column 22 to rotate, thereby enabling the wheel hub to rotate inside the coating box 1. At this time, the operator observes the inside of the coating box 1 through the observation window 11 and moves the moving block 3 left and right. Before coating, the control valve at the connection end of the water spray head 31 and the spray gun head 32 is opened, and water and hot air are sprayed out from the water spray head 31 and the spray gun head 32 respectively to clean and dry the wheel hub, ensuring the cleanliness of the wheel hub and avoiding impurities adhering to the outside of the wheel hub from affecting the coating quality. After cleaning, the control valve at the connection end of the spray gun head 32 is opened, and the paint is sprayed out from the spray gun head 32 to coat the wheel hub. After coating, the wheel hub is quickly dried again by the air jet head 33, which facilitates the subsequent manual removal of the wheel hub, improves the working efficiency of the equipment, has a simple overall structure, small size, is easy to move and transport, has low production cost, and is more convenient for private or small enterprises to use, improving the practicality of coating equipment.
