Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically a paint spray gun for painting automotive parts. Background Technology

[0002] Automobiles are a very important means of transportation in modern life. Automobiles are composed of four main parts: engine, chassis, body and electrical equipment. These four main parts are assembled from various parts, individual parts, and individual parts. After automobile parts are produced, they need to be painted, and some parts need to be painted by workers using hand spray guns.

[0003] A search revealed that patent document CN219168750U discloses a paint gun for painting automotive parts. The gun includes a gun body, a first mounting port fixedly connected to the left end of the gun body, and a second mounting port fixedly connected to the lower part of the gun body. A second mounting block is threadedly connected to the inner wall of the second mounting port, and a paint reservoir is fixedly connected to the lower part of the second mounting block. A paint nozzle is threadedly connected to the left end of the first mounting port. A pull rod is slidably connected inside a fixed frame, and a pressure plate is fixedly connected to the outside of the pull rod. A return spring is wound around the outside of the pull rod, and a limit rod is fixedly connected to the lower end of the pull rod. In this paint gun for painting automotive parts, pulling the pull rod moves the pressure plate and the limit rod upwards. The limit rod disengages from the limit hole, allowing the first mounting block to be manually removed from the second mounting port, thus enabling quick replacement of the paint nozzle in case of blockage.

[0004] However, the spray gun for painting automotive parts has a limited spray range. When dealing with larger parts, the spray range of the spray gun cannot be adapted, resulting in repeated spraying, which can easily affect the quality and efficiency of the paint job. In addition, it has low flexibility and therefore cannot meet the needs of use. Therefore, a spray gun for painting automotive parts is proposed to solve the problems mentioned above.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 4 A paint spray gun for painting automotive parts includes a paint spray gun body 1 and a control button 2 installed inside the paint spray gun body 1 for controlling the painting process. Five nozzles 3 and a housing 7 are located on the right side of the paint spray gun body 1. A multi-port tube 4 is detachably installed on the front of the housing 7. The bottom end of the multi-port tube 4 is fixedly connected to a paint spraying pipe 5 for use with a painting device. Connecting pipes 6, which are flexible hoses, are fixedly connected between the five nozzles 3 and the multi-port tube 4. The multi-port tube 4 is installed outside the housing 7 using bolts and clamps. In use, the nozzles 3 are connected to the painting device via the paint spraying pipe 5 and the connecting pipe 6. The painting device can then be operated to paint the automotive parts using the control button 2.

[0026] To improve the spraying range, in this embodiment, the housing 7 is provided with an adjustment mechanism for adjusting the five nozzles 3. The adjustment mechanism includes a lead screw 9 rotatably installed inside the housing 7, five adjustment plates 11 slidably installed inside the housing 7, and a scissor-type telescopic frame 12 hinged to the outside of the five adjustment plates 11. The lead screw 9 is externally threaded to a slide block 10, and the slide block 10 is fixed to the top adjustment plate 11 by bolts. The five nozzles 3 are respectively fixed to the five adjustment plates 11. A knob 8 is fixedly installed at the top of the lead screw 9.

[0027] Specifically, the scissor-type telescopic frame 12 is composed of a first connecting frame 1201 and a second connecting frame 1202 that are rotatably connected. The scissor-type telescopic frame 12 is hinged to five adjusting plates 11 respectively, and the middle adjusting plate 11 is fixed inside the housing 7. The spacing of the five adjusting plates 11 is adjusted by using the transmission of the lead screw 9 in conjunction with the extension and retraction of the scissor-type telescopic frame 12.

[0028] In this embodiment, the housing 7 has a first sliding groove 13 and a second sliding groove 14 inside. The slide block 10 is slidably installed in the first sliding groove 13, and the lead screw 9 is connected to the first sliding groove 13 and the inside of the housing 7 through a bearing. A guide rod 15, which is connected to and used for limiting the movement of five adjusting plates 11, is fixedly installed in the second sliding groove 14. Five equally spaced sliding sleeves are adjusted on the outside of the guide rod 15, and the five sliding sleeves are connected and fixed to the adjusting plates 11 by bolts. By setting the guide rod 15, the five adjusting plates 11 are limited, enabling them to move linearly and adjusting the stability of the nozzle 3 adjustment.

[0029] It should be noted that the five adjustment plates 11 are equidistantly arranged vertically, and a threaded sleeve that is threadedly connected to the body of the car parts paint gun 1 is fixedly installed on the left side of the housing 7. By utilizing the rotational capability of the threaded sleeve, the five nozzles 3 can be rotated and adjusted so that they can be set in an X and Y axis manner, further improving the practicality of the car parts paint gun body.

[0030] In this embodiment, the exterior of the car parts paint spray gun body 1 is provided with a handle 16, and the top of the handle 16 is welded with a mounting sleeve 17 that is fixed to the exterior of the car parts paint spray gun body 1. The installation of the handle 16 makes it easier for workers to hold the car parts paint spray gun body 1, enabling workers to better perform car parts painting work and enhancing the practicality of the car parts paint spray gun body 1.

[0031] The working principle of the above embodiments is as follows:

[0032] In use, the nozzle 3 is connected to the painting equipment via the paint spray pipe 5 and the connecting pipe 6. The painting equipment can be operated to paint the car parts via the control button 2. When it is necessary to adjust the painting range, hold the knob 8 and turn it to drive the lead screw 9. The rotation of the lead screw 9 drives the threaded sliding block 10 to move up and down. The movement of the sliding block 10 drives the top adjustment plate 11. By extending and retracting the scissor-type telescopic bracket 12, the spacing of the five adjustment plates 11 can be adjusted, thereby adjusting the spacing of the five nozzles 3. This ensures that each area can be evenly and fully sprayed, avoiding repeated spraying or missed areas, and further improving the spraying efficiency.

[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
