Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts processing equipment, specifically a painting device for automotive parts processing. Background Technology

[0002] In the automotive manufacturing and parts processing industry, the painting process is one of the key links to ensure the performance and appearance of automotive parts. There are many types of automotive parts, including housings, brackets, shafts, and irregular structural parts. Their shapes often include complex features such as planes, curved surfaces, grooves, and protrusions. Not only are there strict requirements for the uniformity of paint thickness and adhesion, but it is also necessary to avoid local missed spraying or thin spraying caused by spraying dead corners, so as to ensure the overall quality consistency of the parts.

[0003] A search revealed a Chinese patent with publication number CN217796850U that discloses a painting device for processing automotive parts. The device typically includes a base, a support plate mounted on the base, a support frame supported by the support plate, and a spraying assembly for performing the painting operation. A worktable and fixture are also provided on the upper part of the base to fix the automotive parts.

[0004] Existing painting equipment often uses fixed-angle installation or single-direction translation adjustment structures for its spraying components, which cannot achieve multi-dimensional and wide-range angle adjustment around the parts. For complex curved surfaces commonly found in automotive parts, spraying dead angles are easily formed, resulting in uneven coating thickness on the parts' surfaces. For different specifications of automotive parts, existing equipment requires frequent disassembly and replacement of worktable fixtures or adjustment of the installation position of the spraying components, resulting in poor equipment versatility. Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the above-mentioned background technology, the existing technology has limitations in spray coverage and angle adjustment, as well as poor adaptability and versatility.

[0006] This utility model discloses a painting device for processing automotive parts, comprising a base, two support plates mounted on the upper surface of the base, the upper ends of the two support plates being fixedly connected by a support frame, the lower end of the support frame being U-shaped, an inclined telescopic cylinder being disposed below the base, a connecting assembly being disposed between the telescopic cylinder and the support frame, a fixed shaft being mounted on the upper end of the support frame, a drive source being disposed at the power end of the fixed shaft, an adjustment assembly being disposed between the fixed shaft and the upper end of the telescopic cylinder, and a painting assembly being disposed at the lower end of the telescopic cylinder.

[0007] Furthermore, the connecting assembly includes a limiting frame, which is frame-shaped. A rotating shaft is installed at both ends of the limiting frame, and the rotating shaft is rotatably connected to the lower end of the support frame. The telescopic cylinder is located inside the limiting frame, and a rotating shaft is installed on both the front and rear sides of the limiting frame. The rotating shaft is rotatably mounted on the limiting frame.

[0008] Furthermore, the adjusting assembly includes a connecting rod, which is mounted on the telescopic cylinder and coaxially arranged with the telescopic cylinder. A connecting plate is slidably mounted on the connecting rod, and a horizontal plate is slidably mounted on the lower end of the fixed shaft. A driving component is provided between the horizontal plate and the fixed shaft, and one end of the horizontal plate is rotatably connected to the upper end of the connecting plate via the connecting shaft.

[0009] Furthermore, the driving component includes an adjusting rod, one end of which is rotatably mounted on the horizontal plate, and the other end of which passes through the fixed shaft and is threadedly connected to the fixed shaft.

[0010] Furthermore, the spraying assembly includes a flow divider, the upper end of which is fixedly connected to the telescopic cylinder, and a plurality of spray nozzles are installed at the lower end of the flow divider, the plurality of spray nozzles being evenly distributed.

[0011] Furthermore, mounting holes are provided at the four corners of the base, and a worktable is mounted on the upper surface of the base. The worktable is located below the fixed shaft and is used to install fixtures.

[0012] Furthermore, the end of the horizontal plate near the fixed shaft is configured as a "U" shape, and the adjusting rod is located in the middle of the inner side of the horizontal plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model drives a fixed shaft to rotate via a drive source. The fixed shaft can drive the upper end of the telescopic cylinder to rotate synchronously via a horizontal plate, a connecting shaft, and a connecting plate. At the same time, the limiting frame is rotatably connected to the support frame via a rotating shaft one, and the rotating shaft two supports and limits the telescopic cylinder. This enables the telescopic cylinder to drive the spraying assembly to rotate and adjust in a conical shape around the part. Combined with the telescopic cylinder's own telescopic function and multiple nozzles evenly distributed at the lower end of the distributor, it can cover the surface of the part from multiple dimensions and a large area, effectively eliminating spraying dead corners such as missed spraying and thin spraying, and ensuring that the coating thickness of the part is uniform.

[0014] 2. This utility model allows the adjustment rod to be rotated, which drives the horizontal plate to slide on the fixed shaft. The tilt angle of the telescopic cylinder can then be changed through the connecting plate and connecting rod to adapt to the painting needs of parts of different sizes and shapes. At the same time, different clamps can be installed on the worktable at the top of the base. Without the need for frequent disassembly and replacement of parts, painting operations on various specifications of automotive parts can be realized, improving the versatility of the equipment and increasing processing efficiency.

A connecting component is provided between the telescopic cylinder 6 and the support frame 3. The connecting component includes a limiting frame 4, which is frame-shaped.

The telescopic cylinder 6 is located inside the limiting frame 4, and the front and rear sides of the limiting frame 4 are equipped with rotating shafts 7.

[0020] In this embodiment, the rotating shaft 7 is rotatably mounted on the limiting frame 4, and a fixed shaft 15 is mounted on the upper end of the support frame 3. A drive source 16 is provided at the power end of the fixed shaft 15. The drive source 16 is a servo motor. A planetary gear reducer is provided between the servo motor and the fixed shaft 15. A photoelectric encoder is installed at the end of the fixed shaft 15 to provide real-time feedback of the rotation angle to the control system, thereby realizing "closed-loop control of the spraying trajectory". An adjustment component is provided between the fixed shaft 15 and the upper end of the telescopic cylinder 6. The adjustment component includes a connecting rod 10.

[0021] See Figure 3 , Figure 4 As shown, the connecting rod 10 is mounted on the telescopic cylinder 6, and the telescopic cylinder 6 is coaxially arranged with the connecting rod 10. A connecting plate 11 is slidably mounted on the connecting rod 10. A horizontal plate 13 is slidably mounted on the lower end of the fixed shaft 15. A driving component is provided between the horizontal plate 13 and the fixed shaft 15. The driving component includes an adjusting rod 14. One end of the adjusting rod 14 is rotatably mounted on the horizontal plate 13, and the other end of the adjusting rod 14 passes through the fixed shaft 15. The adjusting rod 14 is threadedly connected to the fixed shaft 15.

[0022] In this embodiment, the end of the horizontal plate 13 near the fixed shaft 15 is set in a "U" shape, the adjusting rod 14 is set in the middle of the inner side of the horizontal plate 13, one end of the horizontal plate 13 is rotatably connected to the upper end of the connecting plate 11 through the connecting shaft 12, the lower end of the telescopic cylinder 6 is provided with a spraying assembly, the spraying assembly includes a distributor 8, the upper end of the distributor 8 is fixedly connected to the telescopic cylinder 6, the top of the distributor 8 is provided with a quick connector, which can be quickly disassembled and connected to an external paint supply pipe, the lower end of the distributor 8 is equipped with multiple nozzles 9, the multiple nozzles 9 are evenly distributed, the nozzles 9 are threadedly connected to the distributor 8, and a fluororubber sealing gasket is installed at the connection to prevent paint leakage.

[0023] The implementation principle is as follows: First, the entire painting device is fixed in the designated work position in the workshop through the mounting hole 17. Then, the car parts to be painted are placed on the worktable on the upper end of the base 1. According to the shape and specifications of the parts, the appropriate clamps are installed on the worktable to firmly fix the parts. For the size and shape of the car parts to be painted; rotate the adjusting rod 14 to drive the horizontal plate 13 to slide on the fixed shaft 15, and the connecting shaft 12 at its end drives the connecting plate 11 to move synchronously. The connecting plate 11 is slidably connected to the connecting rod 10, and the connecting rod 10 is coaxially fixed with the telescopic cylinder 6. Finally, the upper end of the telescopic cylinder 6 moves with the connecting plate 11 to adjust the overall tilt angle of the telescopic cylinder 6 until the initial angle of the spraying component at the lower end of the telescopic cylinder 6 can be adapted to the surface of the part to be painted. Next, the drive source 16 is started, which drives the fixed shaft 15 to rotate around its own axis. When the fixed shaft 15 rotates, it drives the horizontal plate 13 to rotate synchronously. The horizontal plate 13 drives the connecting plate 11 to rotate through the connecting shaft 12. The connecting plate 11 drives the upper end of the telescopic cylinder 6 to rotate through the connecting rod 10. At the same time, the limit frame 4 is rotatably connected to the lower end of the support frame 3 through the first rotating shaft 5 at both ends. When the telescopic cylinder 6 rotates, the limit frame 4 can rotate synchronously with the telescopic cylinder 6 and continuously support and limit the telescopic cylinder 6 through the second rotating shaft 7. Finally, the telescopic cylinder 6 drives the spraying assembly to rotate in a conical shape around the car part fixed on the workbench. By activating the tilted telescopic cylinder 6, the piston rod of the telescopic cylinder 6 is controlled to extend and retract axially; this drives the distributor 8 and the nozzle 9, which are fixedly connected to its lower end, to move closer to or further away from the automotive parts, thus adjusting the spraying distance between the nozzle 9 and the surface of the parts.

[0024] After the entire surface of the parts is coated, first shut off the paint supply system and stop the paint supply from the nozzle 9; then turn off the drive source 16 and the telescopic cylinder 6 in sequence to stop the conical rotation and telescopic movement of the coating assembly and return it to the initial standby position; finally, release the clamps on the worktable, remove the coated car parts, and transfer them to the drying or curing process to complete a single car parts painting operation.
