Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle painting and processing technology, specifically to a lifting spray device for painting special vehicle parts. Background Technology
[0002] In the painting process of special vehicle parts, the performance of the spraying device plays a crucial role in the coating effect. However, the spraying devices commonly available on the market are insufficient in terms of height adjustment and spraying range, making it difficult to meet the complex coating needs of special vehicle parts. Existing spraying devices are often fixed in height, making it impossible to flexibly adjust the spraying height according to the size, shape, and different coating process requirements of the special vehicle parts. For some large or specially shaped special vehicle parts, a spraying height that is too low cannot fully cover the surface of the part, resulting in some areas not being effectively sprayed, affecting the coating quality. On the other hand, a spraying height that is too high may result in insufficient spraying force, which also fails to achieve the ideal coating effect. Frequently changing spraying equipment with different heights is not only time-consuming and labor-intensive, but also increases production costs. Utility Model Content

In conjunction with the positioning device, a servo motor drives a bidirectional screw to control the rotating block to engage or disengage from the triangular limiting groove of the connecting plate, achieving flexible height adjustment to meet the painting height requirements. At the same time, the blocking plate of the limiting device works in conjunction with the rotating spray pipe, using the reaction force generated by the water flow impact to make the rotating spray pipe oscillate in a cycle, expanding the spraying range and ensuring that the special vehicle components are sprayed evenly.

[0023] The outer wall of cylinder 21 is fixedly connected to the inner wall of the bottom of the fixed frame 1, the inner wall of clamping block 22 is fixedly connected to the outer wall of water inlet pipe 4, the outer wall of the top of connecting plate 23 is fixedly connected to the outer wall of the bottom of connecting bent rod 3, the outer wall of connecting plate 23 is slidably connected to the inner wall of the top of fixed frame 1, and the end of rotating spray pipe 5 away from water inlet pipe 4 is rotatably connected to the outer wall of blocking block 6.
[0024] The positioning device 25 includes a fixed ring 251. A servo motor 252 is fixedly connected to the outer wall of the top of the fixed ring 251. A bidirectional screw 253 is fixedly connected to the output end of the servo motor 252. A movable block 254 is threadedly connected to the outer wall of the bidirectional screw 253. A rotating shaft 255 is rotatably connected to the inner wall of the movable block 254. A torsion spring 256 is sleeved on the outside of the rotating shaft 255. A rotating block 257 is fixedly connected to the outer wall of the rotating shaft 255. One end of the torsion spring 256 is fixedly connected to the outer wall of the rotating block 257, and the other end of the torsion spring 256 is fixedly connected to the outer wall of the movable block 254. The outer wall of the fixed ring 251 is fixedly connected to the outer wall of the fixed frame 1. The outer wall of the bottom of the rotating block 257 contacts the outer wall of the top of the limiting strip 8. When it is necessary to fix the connecting plate... When the plate is in position 23, the servo motor 252 is started, and the bidirectional screw 253 at its output end rotates, driving the threaded movable block 254 to move. A torsion spring 256 is sleeved on the rotating shaft 255 inside the movable block 254. The movement of the movable block 254 causes the rotating block 257 to approach the connecting plate 23. The bottom of the rotating block 257 contacts the top of the limiting strip 8 and finally locks into the triangular limiting groove 24 on the outer wall of the connecting plate 23. Using the elastic force of the torsion spring 256 and the limiting provided by the limiting strip 8, the rotating block 257 is stably locked in the groove, thus achieving the positioning of the connecting plate 23.

[0025] The limiting device 7 includes a connecting frame 71. An L-shaped plate 72 is symmetrically fixedly connected to the outer wall of the connecting frame 71.

The outer wall of the connecting frame 71 is fixedly connected to the outer wall of the bottom of the connecting bent rod 3. The outer wall of the L-shaped plate 72 is fixedly connected to the side wall of the connecting bent rod 3. The L-shaped plate 72 is connected to the side wall of the connecting bent rod 3. A guide slope 74 is provided on the top baffle plate 73. Water is pumped into the water pipe 4 from the outside. After the water is introduced, the water is sprayed out from the nozzles on the water pipe 4 and the rotating spray pipe 5 under the obstruction of the baffle block 6. At this time, the rotating spray pipe 5 is moved to make it swing. The water sprayed out by the rotating spray pipe 5 impacts the baffle plate 73. Due to the reaction force of the water, the rotating spray pipe 5 will gradually stop rotating to this side and rotate in the opposite direction to the other side. This cycle is repeated to expand the spray range.
[0026] In use, this special vehicle component painting lifting spraying device, consisting of a fixed frame 1, a lifting device 2, and a limiting device 7, works in concert to provide flexible spraying operation for painting special vehicle components. The fixed frame 1 serves as the basic structure of the entire device, with limiting strips 8 symmetrically fixed to its outer wall to limit the movement of the subsequent lifting device 2 components. The cylinder 21 in the lifting device 2 is fixed to the bottom inner wall of the fixed frame 1. When the cylinder 21 is activated, the clamping block 22 at the top of the cylinder 21 drives the water inlet pipe 4 to rise. The clamping block 22 and... The outer wall of the water inlet pipe 4 is fixedly connected to ensure that the two move synchronously. When the water inlet pipe 4 rises, the rotating spray pipe 5 connected to the water inlet pipe 4 also rises. The end of the rotating spray pipe 5 away from the water inlet pipe 4 is rotatably connected to the blocking block 6, so that the rotating spray pipe 5 can maintain a stable connection during the rising process. The rise of the water inlet pipe 4 will also drive the connecting plate 23 to rise. The connecting plate 23 is fixedly connected to the bottom of the connecting bent rod 3. The connecting bent rod 3 is connected to the limiting device 7 and the blocking block 6, thereby realizing the synchronous movement of multiple components.
[0027] The fixing ring 251 of the positioning device 25 is fixed to the outer wall of the fixing frame 1. The servo motor 252 is installed on the top of the fixing ring 251. When it is necessary to fix the position of the connecting plate 23, the servo motor 252 is started, and the bidirectional screw 253 at its output end rotates, driving the threaded movable block 254 to move. A torsion spring 256 is sleeved on the rotating shaft 255 inside the movable block 254. The movement of the movable block 254 causes the rotating block 257 to approach the connecting plate 23. The bottom of the rotating block 257 contacts the top of the limiting strip 8 and finally locks into the triangular limiting groove 24 on the outer wall of the connecting plate 23. Using the elastic force of the torsion spring 256 and the limiting provided by the limiting strip 8, the rotating block 257 is stably locked in the groove, realizing the positioning of the connecting plate 23, thereby fixing the position of the water inlet pipe 4 and the rotating spray pipe 5. When it is necessary to lower, the servo motor 252 is started to rotate in the opposite direction and contact the thrust provided by the cylinder 21, causing the rotating block 257 to disengage from the triangular limiting groove 24. The connecting plate 23 falls back under the action of gravity.
[0028] The connecting bracket 71 of the limiting device 7 is fixed to the bottom of the connecting bend 3. The L-shaped plate 72 is connected to the side wall of the connecting bend 3. The top baffle plate 73 has a guide slope 74. Water is pumped into the water pipe 4 from the outside. After the water is introduced, the water is blocked by the baffle block 6 and sprayed out from the nozzles on the water pipe 4 and the rotating spray pipe 5. At this time, the rotating spray pipe 5 is moved to make it swing. The water sprayed out by the rotating spray pipe 5 impacts the baffle plate 73. Due to the reaction force of the water, the rotating spray pipe 5 will gradually stop rotating to this side and rotate in the opposite direction to the other side. This cycle is repeated to expand the spraying range and make the special vehicle parts more comprehensively sprayed, thereby improving the uniformity of the coating.
