Description

Technical Field

[0001] The present application relates to the field of automotive exterior part painting, and particularly to a painting structure for automotive exterior parts. Background Art

[0002] Automobile painting processes generally can be divided into two major parts. One is the surface treatment of metal before painting, also called pretreatment technology. The other is the construction process of painting. Surface treatment mainly includes removing oil stains, dust, rust on the surface of workpieces, and removing the old paint layer during repair operations, etc., to improve the surface state of workpieces, including mechanical processing and chemical treatment of the workpiece surface according to various specific situations, such as phosphating, oxidation, and passivation treatments. Automobile body painting refers to covering the surface of the treated object with paint and forming a film after drying. The cured paint film is called a coating film, and a composite layer composed of two or more coating films is called a coating. When painting conventional automotive exterior parts, after the fixing frame is stably installed, a sliding frame is installed on the top of the fixing frame, and several hanging ropes are slidably connected to the bottom end of the sliding frame. The processing materials are fixed by means of the hanging ropes, and the processing materials are moved to a position convenient for painting through the sliding frame.

[0003] Regarding the above related technologies, the inventor believes that when painting conventional processing materials, due to the various shapes of automotive exterior parts, there are likely to be some spraying dead corners that are difficult to spray during spraying. Therefore, multiple spraying ports need to be installed to ensure the spraying effect on the exterior parts, thereby increasing the equipment cost required for spraying automotive exterior parts.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of the present application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content

[0005] In order to solve the problem that it is difficult to spray the exterior parts due to spraying dead corners, the present application provides a painting structure for automotive exterior parts.

[0006] A painting structure for automotive exterior parts provided by the present application adopts the following technical solutions:

[0007] A painting structure for automotive exterior parts includes a fixing frame and a pump body. A sliding frame is fixedly installed on the surface of the fixing frame. Several hanging ropes are slidably connected to the bottom end of the sliding frame. An air outlet pipe is communicated with the top of the pump body. An installation frame is fixedly installed on the surface of the air outlet pipe. One end of the installation frame is welded to the surface of the fixing frame. Several rotating blades are rotatably connected to the surface of the hanging ropes. One end of the pump body is fixedly connected to the surface of the fixing frame. The several rotating blades are distributed in a circumferential array with the center of the hanging rope as the axis, and the rotating blades are semi-circular.

[0008] Preferably, a connecting ring is fixedly installed between several of the rotating blades. A connecting block is rotatably connected to the inner ring wall of the connecting ring. One end of the connecting block is fixedly installed with the bottom end of the hanging rope, and the size specification of the surface of the connecting block is adapted to the size specification of the inner ring wall of the connecting ring.

[0009] Preferably, several springs are fixedly connected to the inner wall of the connecting block. One end of each spring is fixedly installed with a clamping block. A limiting hole adapted to the clamping block is formed in the inner wall of the connecting ring, and the surface of the clamping block is clamped with the inner wall of the limiting hole.

[0010] Preferably, several fixing ropes are fixedly installed at the bottom end of the connecting ring. The bottom ends of the fixing ropes are fixedly connected to a bottom frame. The center of the bottom frame and the center of the connecting ring are on the same straight line, and several installation ropes are clamped at the bottom end of the bottom frame.

[0011] Preferably, a limiting block is clamped on the surface of the installation rope. The surface of the limiting block is slidably connected to the inner wall of the bottom frame, and one end of the limiting block is rotatably installed with a threaded rod. The surface of the threaded rod is threadedly connected to the inner wall of the bottom frame.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] 1. By installing the pump body on the surface of the fixing frame, an air outlet pipe is connected to the top of the pump body. The air outlet pipe is connected to the fixing frame by means of an installation frame. The bottom end of the hanging rope is connected with several rotating blades, so as to blow out strong air flow from one end of the air outlet pipe by means of the air pressure released by the pump body, thereby pushing the rotating blades at the bottom end of the hanging rope and driving the processed material connected to the bottom end of the hanging rope to rotate, facilitating the spraying equipment to spray the processed material at different angles. A connecting ring is installed between several rotating blades. A connecting block is rotatably connected to the inner wall of the connecting ring. The top of the connecting block is installed with the bottom end of the hanging rope, so as to avoid the situation that the rotating blades drive the hanging rope to rotate by means of the connecting ring and the connecting block, resulting in the self-rotation of the hanging rope after the air flow is closed. Springs are installed on the inner wall of the connecting block. One end of the spring is installed with a clamping block. The surface of the clamping block is clamped with the limiting hole in the connecting ring, so as to temporarily limit the position when the raw material rotates to a certain angle, and fix the position of the raw material by means of the clamping block and the limiting hole, facilitating the processing of the coating equipment; compared with the prior art, the spraying effect of the coating equipment on the automotive exterior parts is effectively improved;

[0014] 2. A fixing rope can also be installed at the bottom end of the connecting ring. The bottom end of the fixing rope is connected with a chassis. Several installation ropes are clamped inside the chassis, so as to facilitate the installation of several installation ropes on the top of the workpiece to be processed. In cooperation with several fixing ropes and the chassis, the stability of the workpiece to be processed is effectively improved, avoiding the shaking and rotation of the workpiece to be processed during painting. A limiting block is clamped on the surface of the installation rope. One end of the limiting block is rotatably connected with a threaded rod. The surface of the threaded rod is threadedly installed on the inner wall of the chassis, so as to facilitate the use of the threaded rod to control the limiting block to limit the installation rope, and it is convenient to adjust the length of the installation rope at one end of the limiting block after loosening the threaded rod, so as to install different workpieces to be processed; the stability during the painting of the workpiece to be processed is effectively improved.

The pump body 4 is installed on the surface of the fixing frame 1. The top of the pump body 4 is communicated with an air outlet pipe 5. The air outlet pipe 5 is connected to the fixing frame 1 by means of a mounting frame 6. Several rotating blades 7 are connected to the bottom end of the hanging rope 3. By means of the pump body 4 releasing air pressure to blow out strong air flow from one end of the air outlet pipe 5, the rotating blades 7 at the bottom end of the hanging rope 3 are pushed, driving the workpiece to be processed connected to the bottom end of the hanging rope 3 to rotate, facilitating the spraying equipment to spray different angles of the workpiece to be processed.

[0022] Refer to Figure 1 - Figure 2 , a connecting ring 8 is installed between several rotating blades 7. A connecting block 12 is rotatably connected to the inner wall of the connecting ring 8. The top of the connecting block 12 is installed with the bottom end of the hanging rope 3. By means of the connecting ring 8 and the connecting block 12, it is avoided that the rotation of the rotating blade 7 drives the hanging rope 3 to rotate, resulting in the situation that the hanging rope 3 rotates by itself after the air flow is closed. A spring 11 is installed on the inner wall of the connecting block 12. One end of the spring 11 is installed with a clamping block 10. The surface of the clamping block 10 is clamped with the limiting hole 9 in the connecting ring 8.

[0023] Refer to Figure 3 - Figure 4 , a fixing rope 14 is installed at the bottom end of the connecting ring 8. The bottom end of the fixing rope 14 is connected with a bottom frame 13. Several installation ropes 15 are clamped inside the bottom frame 13.

A limiting block 16 is clamped on the surface of the installation rope 15. One end of the limiting block 16 is rotatably connected with a threaded rod 17. The surface of the threaded rod 17 is threadedly installed on the inner wall of the bottom frame 13. By means of the threaded rod 17, the limiting block 16 is controlled to limit the installation rope 15, and after loosening the threaded rod 17, it is convenient to adjust the length of the installation rope 15 at one end of the limiting block 16, so as to install different processing materials.

The air outlet pipe 5 is connected with the fixing frame 1 by means of the installation frame 6. The bottom end of the hanging rope 3 is connected with several rotating blades 7, so as to blow out strong air flow from one end of the air outlet pipe 5 by means of the air pressure released by the pump body 4, thereby pushing the rotating blades 7 at the bottom end of the hanging rope 3, driving the processing material connected to the bottom end of the hanging rope 3 to rotate, facilitating the spraying equipment to spray different angles of the processing material. A connecting ring 8 is installed between several rotating blades 7. A connecting block 12 is rotatably connected to the inner wall of the connecting ring 8. The top of the connecting block 12 is installed with the bottom end of the hanging rope 3, so as to avoid the situation that the rotation of the rotating blade 7 drives the hanging rope 3 to rotate, resulting in the situation that the hanging rope 3 rotates by itself after the air flow is closed, by means of the connecting ring 8 and the connecting block 12. A spring 11 is installed on the inner wall of the connecting block 12. One end of the spring 11 is installed with a clamping block 10.

[0025] A fixing rope 14 can also be installed at the bottom end of the connecting ring 8. The bottom end of the fixing rope 14 is connected to a chassis 13. Several installation ropes 15 are clamped inside the inner wall of the chassis 13, so as to facilitate the installation of the several installation ropes 15 on the top of the workpiece to be processed. And in cooperation with the several fixing ropes 14 and the chassis 13, the stability of the workpiece to be processed can be effectively improved, avoiding the situation of shaking and rotation of the workpiece to be processed during painting. A limiting block 16 is clamped on the surface of the installation rope 15. One end of the limiting block 16 is rotatably connected to a threaded rod 17.
