[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a continuous wheel hub spraying device, including a fixed bracket 1. The fixed bracket 1 has a first movable arm 2 and a second movable arm 5 on its inner side. The first movable arm 2 and the second movable arm 5 are rotatably connected to the fixed bracket 1. The fixed bracket 1 has a rotary adjustment component on its outer side for controlling the rotation of the first movable arm 2.

[0023] A support plate 3 is provided between the first movable arm 2 and the second movable arm 5. The support plate 3 is fixedly connected to the first movable arm 2 and the second movable arm 5. A rotating clamp for fixing the wheel hub is provided at the upper end of the support plate 3. The rotating clamp is rotatably connected to the support plate 3. An angle adjusting member A for adjusting the tilt angle of the rotating clamp is provided at the lower end of the support plate 3.

[0024] The second movable arm 5 is fixedly equipped with a second nozzle 11 facing the rotating clamp. A first nozzle 8 is provided above and below the second nozzle 11. An angle adjustment component B is provided between the first nozzle 8 and the second movable arm 5.

[0025] The pump is connected to the first spray pipe 8 and the second spray pipe 11 via a hose, and injects the paint from the material tank into the first spray pipe 8 and the second spray pipe 11 for spraying.

[0026] After the wheel hub is fixed on the rotating clamp, the rotating adjustment component drives the first movable arm 2, the support plate 3 and the second movable arm 5 to rotate as a whole. At the same time, the rotating clamp drives the wheel hub to rotate, realizing multi-directional spraying position adjustment. The angle adjustment component A adjusts the tilt angle of the rotating clamp, the first spray pipe 8 sprays the side of the wheel hub, and the angle adjustment component B adjusts the spraying angle of the second spray pipe 11. The second spray pipe 11 sprays the rotating wheel hub from the top and bottom.

[0027] Multi-component linkage enables multi-dimensional adjustment of the hub and nozzle, ensuring no blind spots in spraying. The adjustment structure is highly flexible and can quickly adapt to different spraying needs.

[0028] Regarding the rotary adjustment component:

[0029] The rotary adjustment component includes a rotary motor 4, which is fixedly mounted on the outside of the fixed bracket 1. The output end of the rotary motor 4 is fixedly connected to the first movable arm 2 via a connecting shaft. Since the pallet 3 and the second movable arm 5 are rotatably mounted on the inside of the fixed bracket 1, and the pallet 3 is fixed to the first movable arm 2 and the second movable arm 5, when the rotary motor 4 drives the first movable arm 2 to rotate, the first movable arm 2, the pallet 3, and the second movable arm 5 will rotate as a whole, adjusting the hub spraying area.

[0030] Regarding rotating clamps:

[0031] The rotating clamp includes a tensioning cylinder 10, an adjusting seat 13, and a tray 17. The tray 17 is fitted over the outside of the tensioning cylinder 10, and the tensioning cylinder 10 is fixedly connected to the tray 17. An adjusting groove 14 is provided at the upper end of the tray 3. The adjusting seat 13 passes through the adjusting groove 14 and is rotatably connected to it. The lower end of the tensioning cylinder 10 is rotatably connected to the adjusting seat 13. A drive motor for controlling the rotation of the tensioning cylinder 10 is located inside the adjusting seat 13. The drive motor is installed inside the adjusting seat 13, and its output end is fixed to the lower end of the tensioning cylinder 10. When the hub is fitted over the outside of the tensioning cylinder 10, the tray 17 supports the hub from the hub base plate. The rotary motor 4 controls the rotation of the tensioning cylinder 10, which in turn drives the hub to rotate, ensuring that the paint can fully cover the surface of the hub.

[0032] It is worth explaining in detail that a pin hole is provided on the outer side of the tensioning cylinder 10, and an elastic pin 19 is provided in the pin hole. The elastic pin 19 is slidably connected to the pin hole. A pressure block 15 is provided on the inner side of the tensioning cylinder 10. The pressure block 15 is placed above the elastic pin 19. A fourth air push rod 18 is provided at the upper end of the tensioning cylinder 10. The output end of the fourth air push rod 18 is fixedly connected to the pressure block 15.

[0033] Using an elastic pin 19 to fix the workpiece sleeved on the outside of the tensioning cylinder 10 is a common fixing method for the tensioning cylinder 10. During the fixing process, the fourth air push rod 18 pushes the pressure block 15 down. After the pressure block 15 falls, it pushes the elastic pin 19, pushing it outward from the pin hole. After being pushed outward, the elastic pin 19 contacts the inner wall of the inner ring of the hub. By continuously applying pressure, it ensures that the hub will not detach from the tensioning cylinder 10. The elastic pin 19 has a built-in spring return structure, which can retract into the pin hole after the pressure block 15 is retracted. Since the spring return structure is a conventional solution, it will not be described in detail here.

[0034] Since the tensioning cylinder 10 drives the hub to rotate by its own rotation, the fourth air push rod 18 needs to be connected to the air pump conduit using a slip ring structure.

[0035] The tilt angle of the rotating clamp is adjusted by the angle adjusting component A, which includes a third pneumatic push rod 16. The third pneumatic push rod 16 is located below the support plate 3, with its mounting end rotatably connected to the lower end of the support plate 3 and its output end rotatably connected to the lower end of the adjusting seat 13. When the third pneumatic push rod 16 pushes the bottom of the adjusting seat 13, the lower end of the adjusting seat 13 will rotate to the left, and the tensioning cylinder 10 fixed to the top of the adjusting seat 13 will cause the hub to tilt to the right.

[0036] The spraying angle of the first nozzle 8 is adjusted by the angle adjustment component B. The angle adjustment component B includes a positioning plate 7, which is placed between the rotating clamp and the second movable arm 5. The upper and lower ends of the positioning plate 7 are respectively hinged to the two first nozzles 8. A second air push rod 12 is provided on the side of the positioning plate 7 away from the rotating clamp. The mounting end of the second air push rod 12 is rotatably connected to the positioning plate 7, and the output end of the second air push rod 12 is rotatably connected to the first nozzle 8.

[0037] The positioning plate 7 is equipped with two second air push rods 12, which control the two first spray pipes 8 respectively, thereby adjusting the spraying angle of the first spray pipes 8 at the top and bottom of the wheel hub to ensure that the paint can be evenly covered on the upper and lower surfaces of the wheel hub.

[0038] More specifically, a first air push rod 6 is provided between the positioning plate 7 and the fixed bracket 1. The mounting end of the first air push rod 6 is fixedly connected to the second movable arm 5, and the output end of the first air push rod 6 is fixedly connected to the positioning plate 7. A through hole is provided on the positioning plate 7, and the second spray pipe 11 passes through the through hole and is slidably connected to the through hole. By pushing the positioning plate 7 with the first air push rod 6, the positioning plate 7 will drive the first spray pipe 8 to move closer to the rotating fixture, adjusting the spraying area of ​​the first spray pipe 8 and further improving the spraying flexibility of the first spray pipe 8.

[0039] How this application works:

[0040] The pump is connected to the first spray pipe 8 and the second spray pipe 11 via a hose, injecting paint from the material tank into the first spray pipe 8 and the second spray pipe 11 for spraying. During the spraying operation, the hub is first fitted onto the rotating clamp. After the hub is fixed, the rotating adjustment component drives the first movable arm 2, the support plate 3, and the second movable arm 5 to rotate as a whole. At the same time, the rotating clamp drives the hub to rotate, realizing multi-directional spraying position adjustment. The angle adjustment component A adjusts the tilt angle of the rotating clamp, and the first spray pipe 8 sprays the side of the hub. The angle adjustment component B adjusts the spraying angle of the second spray pipe 11, and the second spray pipe 11 sprays the rotating hub from the top and bottom.
