[0026] Reference Figure 2-4This utility model provides an embodiment of a painting device for vehicle frame production, including a paint spraying box 1. A support frame 5 is fixedly connected to the bottom of the paint spraying box 1, and a box door 4 is connected to the top of the paint spraying box 1 via a first driving component to control the opening of the box door 4 and the movement of the support plate 11. The first driving component includes an electric slide rod 2 fixedly connected to the top of the paint spraying box 1, a driving rod 3 slidably connected to the outer wall of the electric slide rod 2, and the left end of the driving rod 3 fixedly connected to the right end of the box door 4. A connecting block 13 is fixedly connected to the bottom of the inner wall of the paint spraying box 1. The box door 4... A bearing plate 11 is fixedly connected to the right end. The bottom end of the bearing plate 11 is slidably connected to the top end of the connecting block 13. Fixing components are provided on both the left and right sides of the top end of the bearing plate 11. The fixing components include fixing blocks 12 fixedly connected to both the left and right sides of the top end of the bearing plate 11. The inner wall of the fixing block 12 is rotatably connected to a two-way threaded rod 19. The outer wall of the two-way threaded rod 19 is threadedly connected to a clamping plate 20 on both the front and rear sides. A one-way valve 9 is provided on the inner wall of the box door 4. A sealing ring 10 is fixedly connected to the right end of the box door 4. The outer wall of the sealing ring 10 is attached to the inner wall of the paint spray box 1.

[0027] Specifically, the electric slide rod 2 controls the drive rod 3 to open the box door 4, causing the bearing plate 11 to slide out from the connecting block 13, placing the frame on the fixing block 12. The double-threaded rod 19 is rotated to make the two clamping plates 20 move in opposite directions to clamp and fix the frame. Then, the electric slide rod 2 controls the drive rod 3 to reset the box door 4, which fits with the sealing ring 10 on the right end of the box door 4 to fit into the paint box 1, improving the overall sealing of the device and preventing gas leakage.

[0028] Reference Figure 1 , Figure 3 and Figure 5 The inner wall of the paint spray box 1 is connected to an arc-shaped slide rail 14 via a second driving component, which is used to drive the arc-shaped slide rail 14 to move and spray paint on the vehicle frame. The second driving component includes a drive motor 18 fixedly connected to the front side of the inner wall of the paint spray box 1. A screw 16 is fixedly connected to the drive end of the drive motor 18. A guide rod 17 is fixedly connected to the rear side of the inner wall of the paint spray box 1. The left end of the screw 16 is rotatably connected to the inner wall of the paint spray box 1. A slider 15 is threadedly connected to the outer wall of the screw 16. Another slider 15 is slidably connected to the outer wall of the guide rod 17. One end of the arc-shaped slide rail 14 is fixedly connected to the opposite end of the two sliders 15.

A fan 7 is fixedly connected to the front end of the filter box 6.

[0029] Specifically, after the door 4 is closed, the screw 16 can be driven to rotate by the drive motor 18, so that the slider 15 slides along the inside of the paint spray box 1 under the guidance of the guide rod 17. With the help of the nozzle 22 on the arc-shaped slide rail 14, the frame can be painted. At the same time, the nozzle 22 can change the painting angle by sliding the slider 21 inside the arc-shaped slide rail 14. During the painting process, the blower 7 can create a negative pressure inside the filter box 6. With the help of the air supply pipe 8, the irritating gas generated inside the paint spray box 1 due to the painting is sucked into the filter box 6 for treatment. The one-way valve 9 set on the inner wall of the door 4 can allow clean air from the outside to enter the paint spray box 1 during this process, maintaining the air pressure balance inside the paint spray box 1.

[0030] Working principle: The electric slide bar 2 controls the drive rod 3 to open the box door 4, causing the bearing plate 11 to slide out from the connecting block 13, placing the frame on the fixing block 12. Rotating the bidirectional threaded rod 19 causes the two clamping plates 20 to move towards each other, clamping and fixing the frame. Then, the electric slide bar 2 controls the drive rod 3 to reset the box door 4. The sealing ring 10 on the right end of the box door 4 fits against the paint spray box 1, improving the overall sealing of the device and preventing gas leakage. After the box door 4 is closed, the drive motor 18 drives the screw 16 to rotate, causing the slider 15... Guided by the guide rod 17, the spray gun slides inside the paint spray box 1. With the help of the nozzle 22 on the arc-shaped slide rail 14, the frame can be painted. At the same time, the nozzle 22 can slide inside the arc-shaped slide rail 14 via the slider 21 to change the spraying angle. During the painting process, the blower 7 can create a negative pressure inside the filter box 6. With the help of the air supply pipe 8, the irritating gas generated inside the paint spray box 1 due to the painting is sucked into the filter box 6 for treatment. The one-way valve 9 set on the inner wall of the box door 4 can allow clean air from the outside to enter the paint spray box 1 during this process, maintaining the air pressure balance inside the paint spray box 1.
