Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing equipment technology, specifically a spraying structure for mechanical parts processing. Background Technology

[0002] In the machining of mechanical parts, spraying is mainly used to improve the surface performance and service life of the parts. By spraying anti-rust paint, wear-resistant coatings, or special coatings, metal corrosion can be effectively prevented, friction and wear can be reduced, and the high-temperature resistance, corrosion resistance, or insulation properties of the parts can be enhanced. In addition, spraying can also improve the appearance of parts and meet the surface quality requirements of specific industries (such as automotive and aerospace). Compared with other surface treatment processes, spraying has advantages such as low cost, wide applicability, and flexible operation, and is especially suitable for surface protection and functional optimization of complex-shaped parts.

[0003] The application number "202322737571.0" discloses a "spraying device for machining mechanical parts," which "includes a base, a storage tank, a feeding pump, a feed box, and a fixed frame on the top of the base. The storage tank, feeding pump, and feed box are connected in sequence. A first rotating rod is rotatably installed inside the feed box, and an impeller is fixedly sleeved on the outer wall of the first rotating rod. A paint spraying box is connected to one side of the feed box via a hose, and a paint spraying pipe is provided on one side of the paint spraying box. A second rotating rod is rotatably installed inside the fixed frame, and a hook is provided at the bottom of the second rotating rod. The second rotating rod is drivenly connected to the first rotating rod. A drying component is provided on one side of the fixed frame." This utility model, through the above-mentioned configuration, enables the part to be sprayed and rotated simultaneously, achieving a simple and effective process of uniformly spraying paint on the surface of the part, saving manpower, and improving the spraying efficiency of the part.

[0004] However, the above method still has the following drawbacks: by rotating the parts at the bottom of the hook, the parts can be painted and rotated at the same time, which can ensure the uniformity of the spraying. However, it requires transmission through the first pulley, belt, second pulley and second rotating rod, making it difficult to fix multiple parts at the same time and rotate them, resulting in low spraying efficiency.

The suspension system, by connecting the spray nozzle 13 to the spray pump, enables the spraying of the surface of mechanical parts. The cylinder 7 drives the rack 5, and since the gear 4 meshes with the rack 5, the rack 5 can drive several rotating shafts 2 to rotate synchronously. The rotating shafts 2 can drive the hanger 3 to rotate, thereby adjusting the angle of the mechanical parts, ensuring the uniformity of the spraying, and enabling the simultaneous spraying of multiple mechanical parts, thus improving the spraying efficiency of mechanical parts. The structure is simple and easy to use. The guide component 6 can support and guide the rack 5, preventing the rack 5 from tilting and ensuring the positional accuracy of the rack 5. The support component 15 can provide support for the spray nozzle 13 and adjust the height of the spray nozzle 13. In this embodiment, preferably, the guide assembly 6 includes an end plate 601.

When the slide block 801 is driven to move horizontally by the cylinder 7, the slider 805 and the guide rail 11 can guide the slide block 801 and prevent the slide block 801 from tilting. The slide block 801 can control the horizontal displacement of the rack 5 through the limiting rod 802 and the limiting plate 9. By pulling the limiting rod 802 and causing the push plate 803 to compress the spring 804, the top of the limiting rod 802 can be pulled out from the rod groove 10, and the rack 5 can be disassembled without causing interference. In this embodiment, preferably, the support assembly 15 includes a support 1501, a reinforcing plate fixedly disposed in the middle of the support 1501, the bottom end of the support 1501 fixedly connected to the bottom of the bracket 12, cylinders 1502 fixedly mounted on both sides of the support 1501, the telescopic rods of the cylinders 1502 fixedly connected to a support plate 1503, the nozzle 13 fixedly mounted on one side of the support plate 1503, a sliding groove opened at the top of the support 1501, and a sliding rod 1504 slidably connected to the top of the support 1501 through the sliding groove. The top end of the nozzle is fixedly connected to the bottom end of the support plate 1503. The second cylinder 1502 can be fixed through the support 1501. The second cylinder 1502 can provide support for the support plate 1503, and the support plate 1503 can provide support for the nozzle 13. By controlling the extension and retraction of the second cylinder 1502, the second cylinder 1502 can drive the support plate 1503 to rise and fall, thereby adjusting the height of the nozzle 13. It has good flexibility. The setting of the slide bar 1504 can improve the stability of the support plate 1503. The support plate 1503 is not easy to tilt and is stable and reliable. In this embodiment, preferably, a plurality of nozzles 14 are fixedly provided on the surface of the spray pipe 13, a connector is installed at the input end of the spray pipe 13, and a hose 16 is fixedly connected to the input end of the spray pipe 13 through the connector. The spray head 14 can spray the coating liquid evenly, and the hose 16 can ensure the lifting and lowering ability of the spray pipe 13, and will not interfere with it during the height adjustment process.

[0020] In use, first connect the hose 16 to the output end of the spray pump, then suspend the mechanical parts sequentially on the hanger 3 at the bottom of the rotating shaft 2. The hanger 3 can limit the position of the parts and keep the bottom of the mechanical parts suspended. Then, the spray pump pumps the spray liquid, and the nozzle 14 can spray the spray liquid onto the surface of the parts. During this process, when the cylinder 7 drives the slide 801 of the limiting component 8 to move horizontally, the slider 805 and the guide rail 11 can guide the slide 801 to prevent the slide 801 from tilting. The slide 801 can control the horizontal displacement of the rack 5 through the limiting rod 802 and the limiting plate 9. Since the gear 4 and the rack 5 are meshed, the rack 5 can drive several rotating shafts 2 to rotate synchronously through the gear 4. The rotating shaft 2 can drive the hanger 3 to rotate, so that the angle of the mechanical parts can be adjusted, ensuring the uniformity of the spray and allowing multiple mechanical parts to be sprayed at the same time. When the rack 5 moves, the guide rod 602 of the guide assembly 6 can support and guide the rack 5 through the sleeve 603, which can ensure the positional accuracy of the rack 5 and avoid the rack 5 from deviating. When it is necessary to spray mechanical parts of different heights, the extension and retraction of the cylinder 1502 can be controlled. The cylinder 1502 can drive the support plate 1503 to rise and fall, which can adjust the height of the nozzle 13. It has good flexibility. The sliding rod 1504 can improve the stability of the support plate 1503, and the support plate 1503 is not easy to tilt. The hose 16 can ensure the lifting and lowering ability of the nozzle 13 and will not interfere with it during the height adjustment process. After the parts are sprayed, the spraying pump and cylinder 7 can be stopped. When the slide 801 needs to be disassembled, pull the limit rod 802 to compress the spring 804 with the push plate 803. This will pull the top of the limit rod 802 out of the rod groove 10. Then, the slide 801 can be disassembled from one end of the telescopic rod of cylinder 7. The slider 805 can be slid out from the guide rail 11 to remove the slide 801. By loosening the nut 606, the guide rod 602 can be pulled out. This allows the guide rod 602 and the rack 5 to be disassembled for easy maintenance and replacement.
