As the part where the axle is installed, it is used to support the tire, cushion external impact, achieve contact between the tire and the road, and transfer the weight of the car body to the road. At the same time, it protects the tire and internal components of the wheel hub, preventing the tire from being damaged due to impact during driving. Since the materials used to make automobile wheel hub steel rims are mostly steel or aluminum alloys, they are easily corroded by rain, snow and other corrosive substances in the air when exposed to the external environment for a long time, which will cause the surface of the steel rim to rust. Therefore, it is necessary to spray an anti-rust coating on the surface of the steel rim to improve the corrosion resistance of the steel rim.
[0003] The shortcomings of the existing technology: The anti-rust coating on the surface of the wheel hub steel rim in the existing technology can usually only be sprayed on one side first during the spraying process, and then the wheel hub steel rim is turned over and the other side is sprayed. Since the wheel hub steel rim is heavy, the operation is very inconvenient and the work efficiency is low. At the same time, the wheel hub steel rim needs to be naturally dried after spraying, and a lot of time is wasted waiting for the anti-rust coating on the surface to dry and form a protective film.

[0022] Further, such as Figure 3 As shown, the fixing assembly 5 includes a slider 51 movably connected to the inner cavity of the movable groove 4, the top of the slider 51 is fixedly connected to a stabilizing block 53, the top of the stabilizing block 53 is provided with an insert rod 54, and the top two sides of the slider 51 are fixedly connected to push rods 55.
[0023] Further, such as Figure 3As shown, a motor 52 is fixedly installed at the bottom end of the slider 51, and the output end of the motor 52 passes through the slider 51 and is fixedly connected to the bottom end of the insertion rod 54. The motor 52 enables the insertion rod 54 to rotate. During the spraying process, the hub steel ring is rotated by the insertion rod 54 to achieve all-round spraying operation. A connecting block 56 is fixedly connected to one side of the bottom end of the slider 51.
[0024] Further, such as Figure 3 and Figure 4 As shown, the outer surface of the insertion rod 54 is provided with a hub steel ring, and the steel ring hub to be sprayed is placed on the outer surface of the insertion rod 54, so that the steel ring hub can be suspended in mid-air, ensuring that the hub steel ring can achieve all-round spraying operation without turning it over. The position of the push rod 55 corresponds to the position of the warehouse door 12. When the slider 51 moves in the inner cavity of the movable groove 4, as the slider 51 moves forward, the push rod 55 pushes the warehouse door 12 open, ensuring that the hub steel ring can smoothly enter the inner cavity of the drying box 3.
[0025] Further, such as Figure 2 As shown, a cylinder 16 is fixedly installed on one side of the bottom end of the workbench 1, and the output end of the cylinder 16 is fixedly connected to one end of the connecting block 56. Through the push-pull movement of the output end of the cylinder 16, the slider 51 can reciprocate in the inner cavity of the movable groove 4.
[0026] Further, such as Figure 1 As shown, one end of the spray tank 2 is fixedly connected to a support plate 6, a paint bucket 7 is fixedly installed on the top of the support plate 6, both ends of the paint bucket 7 are fixedly connected to a paint pump 8, the output end of the paint pump 8 is fixedly connected to a paint pipe 9, one end of the paint pipe 9 passes through the spray tank 2 and is fixedly connected to a high-pressure nozzle 10, and the anti-rust paint in the inner cavity of the paint bucket 7 is sprayed on the wheel hub steel rim through the high-pressure nozzle 10. The design of multiple high-pressure nozzles 10 ensures that the wheel hub steel rim can be sprayed evenly.
[0027] Furthermore, a door 14 is provided at the top of the drying box 3, and hot air blowers 15 are provided on both sides of the inner cavity of the drying box 3. After the wheel hub steel rim is transferred to the inner cavity of the drying box 3, it is dried by the hot air blower 15 to prevent the anti-rust paint on the surface from being rubbed off during the movement, affecting the use effect, and at the same time reducing the time wasted by natural drying.
[0028] The working principle of the present invention is as follows: first, the output end of the cylinder 16 is retracted to the shortest, the fixing assembly 5 is located in the inner cavity of the drying box 3, the box door 14 is opened, the wheel hub steel ring that needs to be sprayed with the anti-rust coating is placed on the outer surface of the insertion rod 54, and the wheel hub steel ring is pressed down by its own weight to ensure stability. After the fixing is completed, the box door 14 is closed and the cylinder 16 is started at the same time. When the output end of the cylinder 16 is extended to the longest, the connecting block 56 is pushed to make the slider 51 move from the inner cavity of the moving groove 4 to the inner cavity of the spraying bin 2. During the spraying process, the anti-rust coating in the inner cavity of the paint bucket 7 is sprayed on the wheel hub steel ring through the high-pressure nozzle 10. The design of multiple high-pressure nozzles 10 ensures that the wheel hub steel ring can be sprayed evenly. The motor 5 is started at the same time during the spraying process. 2. The motor 52 rotates the rod 54, driving the wheel hub steel rim to rotate slowly, ensuring that the wheel hub steel rim can be sprayed evenly. At the same time, the rod 54 makes the steel rim hub hang in the air, ensuring that the wheel hub steel rim can achieve all-round spraying operation without turning over. After the spraying is completed, the cylinder 16 is started, and the output end of the cylinder 16 is retracted to the shortest, and the wheel hub steel rim is moved to the inner cavity of the drying box 3 through the transfer port 11. During the movement of the slider 51, the door 12 on both sides is pushed open by the push rod 55. After the movement is completed, the door 12 is automatically closed by the self-rebound hinge 13. After entering the inner cavity of the drying box 3, the hot air blower 15 is started to dry the wheel hub steel rim, so that the anti-rust coating on the surface of the wheel hub steel rim is quickly dried to form a protective film.
