[0002] Automobile leaf springs, also known as leaf springs, are composed of a series of steel plates of unequal length and curvature. They are the most popular elastic elements in automobile suspension systems. During the manufacturing process, in order to improve the durability and corrosion resistance of the leaf spring surface, it is often painted.
[0003] However, the currently commonly used painting process has a significant drawback. This process usually requires the leaf spring to be fixed on a specific fixture for the spraying operation. However, this means that during the spraying process, the part where the fixture contacts the leaf spring will not be sprayed, resulting in an incomplete spraying effect and missing coating in some areas.
[0004] In addition, this spraying method has other limitations. On the one hand, it is difficult to achieve simultaneous spraying of multiple leaf springs through a simple structural design, which undoubtedly reduces production efficiency. On the other hand, the leaf springs need to be air-dried after spraying, and the current process often makes it difficult to directly integrate the air-drying process into the spraying process, which undoubtedly increases the complexity and cost of the production process.
[0005] Therefore, it is very necessary to invent a paint spraying device for producing leaf springs. Utility Model Content

Two vertical plates are provided, the base is fixedly installed at the lower end of the vertical plate, the cross beam is fixedly installed on the inner side above the two vertical plates, the hook is fixedly installed under the cross beam, and the leaf spring is suspended on the hook.
[0009] Preferably, the cross beam plate is located below the lifting shaft, the cross beam plate is a rectangular plate, and through holes are opened at both ends of the cross beam plate to allow the steel cable to slide through; the cross beam plate is located above the spray plate.

[0021] As attached Figure 1 To Attachment Figure 3 As shown:
[0022] The utility model provides a paint layer spraying device for leaf spring production, comprising a leaf spring hanger 1, a lifting full-type spraying mechanism 2 and a leaf spring 3. The lifting full-type spraying mechanism 2 is installed on the leaf spring hanger 1, the leaf spring 3 is located on the inner side of the lifting full-type spraying mechanism 2, and the leaf spring 3 is suspended on the leaf spring hanger 1.
[0023] The lifting full-type spraying mechanism 2 includes a lifting shaft 21, a driving motor 22, a winding disk 23, a steel cable 24, a spraying plate 25, a spraying box 26, an air-drying fan 27, a spraying tank 28 and a spray head 29. The lifting shaft 21 is rotatably mounted on the vertical plate 11 of the leaf spring hanger 1, and any end thereof rotates through the vertical plate 11 and is fixedly connected to the output end of the driving motor 22 fixedly mounted on the outside of the vertical plate 11; the winding disks 23 are fixedly mounted at both ends of the lifting shaft 21, and the winding disks 23 are wound with the steel cable 24, the lower end of the steel cable 24 is fixedly connected to the spray plate 25, and the spray plate 25 is slidably connected to the vertical plate 11 through a guide rail; the spray box 26 and the air-drying fan 27 are fixedly installed on the upper and lower ends of the spray plate 25, and the spray head 29 is fixedly installed on the inner wall of the spray groove 28 opened on the spray plate 25, and the spray head 29 is connected to the pumping equipment installed on the spray box 26. The lifting and comprehensive spraying mechanism 2 can flexibly adjust the position of the spray plate 25 through precise lifting and lowering actions to achieve comprehensive spraying of the leaf spring 3.
[0024] Embodiment 1:
[0025] Specifically, the leaf spring hanger 1 includes a base 12, a cross beam 13 and a hook 14. Two vertical plates 11 are provided. The base 12 is fixedly installed at the lower end of the vertical plate 11, the cross beam 13 is fixedly installed on the inner side of the two vertical plates 11, and the hook 14 is fixedly installed below the cross beam 13. The leaf spring 3 is suspended on the hook 14, and the leaf spring hanger 1 provides a stable suspension environment for the leaf spring 3. The vertical plate 11 supports the lifting full-type spraying mechanism 2 to ensure the smooth progress of the spraying process.
[0026] Specifically, the cross beam plate 13 is located below the lifting shaft 21. The cross beam plate 13 is a rectangular plate, which is convenient for fixing and mounting with the vertical plate. It is particularly worth mentioning that through holes are provided at both ends of the cross beam plate 13 to allow the steel cable 24 to slide through. This design ensures smooth lifting and lowering. In addition, the cross beam plate 13 is located above the spraying plate 25, providing sufficient space for spraying operations.
[0027] Specifically, the spray plate 25 is a rectangular structure, and the two air-drying fans 27 are fixedly installed at the upper ends of the spray plate 25. When the two fans are working, an air convection area can be formed, which effectively accelerates the drying speed of the paint on the surface of the leaf spring 3 and improves production efficiency. At the same time, two spray boxes 26 are fixedly installed at the lower ends of the spray plate 25. The two spray boxes 26 are responsible for supplying paint respectively, and evenly transport the paint to the spray head 29 through a pipe connected to the spray head 29. The spray heads are arranged in a circular array in the spray tank 28, which can realize all-round spraying of the leaf spring 3 and ensure that the coating is uniform and without omission.
[0028] Specifically, the several spraying slots 28 opened on the spraying plate 25 are circular slots, and their design is ingenious in that they can allow the steel leaf spring 3 directly above to pass through. This design allows the steel leaf spring 3 to pass through the spraying area smoothly in a suspended state without any hindrance. At the same time, the circular design of the spraying slot 28 also helps the paint to form a uniform coating on the surface of the steel leaf spring 3, avoiding uneven coating thickness or omissions. A circular array layout of spray heads 29 is used in each spraying slot 28. This layout ensures that the spray heads 29 can spray the steel leaf spring 3 in all directions and at multiple angles, thereby achieving comprehensive coverage of the surface of the steel leaf spring 3. The spray heads 29 are connected to the pumping equipment of the spray box 26, and can continuously and stably supply paint to ensure the continuity and stability of the spraying operation.
[0029] Embodiment 2:
[0030] First, the leaf spring 3 is suspended on the hook 14 of the leaf spring hanger 1 to ensure that the leaf spring 3 is stable and vertically suspended. At this time, the lifting full-face spraying mechanism 2 is in the initial position, and the spraying plate 25 is located below the leaf spring 3.
[0031] Next, the drive motor 22 is started, and the output end of the drive motor 22 drives the lifting shaft 21 to rotate. Since winding disks 23 are fixedly installed at both ends of the lifting shaft 21, and steel cables 24 are wound around the winding disks 23, and the lower ends of the steel cables 24 are fixedly connected to the spraying plate 25, the rotation of the lifting shaft 21 causes the steel cables 24 to be wound or released on the winding disks 23, thereby driving the spraying plate 25 to slide up and down on the vertical plate 11 along the guide rails. In this way, the lifting full-type spraying mechanism 2 can realize the precise lifting and lowering action of the spraying plate 25, so that the spraying plate 25 can be flexibly adjusted to an appropriate position to adapt to the leaf springs 3 of different heights and widths.
[0032] During the process of the spray plate 25 sliding up and down, the spray box 26 starts to work, and the paint is delivered to the spray head 29 through the pumping device. The spray head 29 is arranged in a circular array in the spray tank 28, and can spray the leaf spring 3 in all directions and at multiple angles. Since the design of the spray tank 28 allows the leaf spring 3 to pass through, the leaf spring 3 can pass through the spray area smoothly during the spraying process, ensuring that the coating is uniform and without omission.
[0033] After the spraying is completed, the driving motor 22 continues to work, and the pumping device of the lifting full-face spraying mechanism 2 stops working. At this time, the spraying plate 25 continues to slide up and down, and the air-drying fan 27 is turned on to work, forming an air convection area to quickly dry the leaf spring 3. The design of the air-drying fan 27 allows air to flow evenly over the surface of the leaf spring 3, accelerating the drying speed of the paint and improving production efficiency.
[0034] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
