Description

Technical Field

[0001] The utility model relates to spraying technology in the field of machining, and particularly relates to a spraying shielding tooling specifically designed for a sealing ring. Background Art

[0002] In the existing spraying process, spraying operations for non-standard sealing rings often face problems such as difficult precision control, low production efficiency, and adhesion after spraying. Traditional spraying tooling often has difficulty adapting to non-standard sealing rings of different specifications, resulting in inaccurate definition of the spraying area and affecting the spraying quality. In addition, after spraying, the adhesion between the sealing ring and the tooling also increases the difficulty and cost of subsequent processing.

[0003] In the prior art, a shielding tooling has been developed, that is, precise shielding of components is achieved through the close cooperation of multiple components. These components may include multiple customized parts, such as complex jigs, baffles, gaskets, etc. These components need to be precisely installed around the sealing ring to ensure that the paint will not be splashed onto non-target areas during the spraying process. However, this design often results in an extremely cumbersome disassembly and assembly process of the tooling, requiring a large amount of time and manpower. In addition, due to the large number of components and complex structures, the manufacturing cost of the tooling is relatively high. Summary of the Invention

[0004] Aiming at the problems existing in the above background art, the utility model aims to provide a spraying shielding tooling for a sealing ring to solve the problems of high cost, low efficiency, and adhesion during the spraying process of non-standard sealing rings.

[0005] The purpose of the utility model is achieved as follows: A spraying shielding tooling for a sealing ring includes: a bottom plate, on which a positioning structure is provided; inner baffles, there are multiple inner baffles, each of which is designed with a connecting mechanism, and after being spliced, they form an annular structure, which is arranged around the inner edge of the sealing ring and is used to clamp the side of the sealing ring for shielding. Each inner baffle is installed on the bottom plate and is fixedly connected to the bottom plate through bolt one and nut; upper baffles, there are several upper baffles, the upper baffles are located above the sealing ring, and their shapes match the top contour of the sealing ring. The upper baffles are fixed on the bottom plate through bolt two. The inner baffle is located inside the sealing ring and is used to block the areas that do not need to be sprayed to ensure the accuracy of spraying.

[0006] Further, a central positioning hole or protrusion, and multiple positioning grooves or protrusions distributed around the center are provided on the bottom plate.

[0007] Further, the number and shape of the inner baffles match the inner diameter and height of the sealing ring to ensure that the spliced annular structure can closely fit the inner wall of the sealing ring.

[0008] Further, the shape of the upper baffle includes, but is not limited to, circular, rectangular, or other shapes that match the shape of the top of the sealing ring.

[0009] Further, the overall design of the tooling is a modular structure, where each component is detachable and replaceable.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: improving spraying accuracy: through precise masking design, it ensures that the spraying area is accurate, thereby improving the spraying quality; reducing adhesion phenomenon: the structural design of the tooling effectively avoids the adhesion problem between the sealing ring and the tooling after spraying, reducing the difficulty and cost of subsequent processing; improving production efficiency: the tooling structure is stable and reliable, easy to install and disassemble, reducing the clamping and replacement time during spraying, and improving production efficiency.

[0014] The following further describes the present utility model in conjunction with embodiments. The described embodiments are only a part of the embodiments of the present utility model, not all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the protection scope of the present utility model.

[0015] As Figure 1 and Figure 2 shown, a spraying masking tooling for a sealing ring in the present application includes an inner baffle 1, a bolt one 2, a sealing ring 3, an upper baffle 4, a nut 5, a bolt two 6, and a bottom plate 7.

[0016] As Figure 2 shown, the bottom plate 7 is located at the bottom of the tooling and serves as the basis for support and positioning. The bottom plate is provided with positioning structures such as a central positioning hole, a protrusion, or a positioning groove for precisely aligning and fixing the sealing ring.

[0017] As Figure 2 shown, there are multiple inner baffles 1. The number of inner baffles is determined according to the inner diameter size and height of the sealing ring. They are spliced to form an annular structure and are arranged around the inner edge of the sealing ring and fixed to the bottom plate through bolts one 2 and nuts 5.

[0018] As Figure 2 shown, the upper baffle 4 is located above the sealing ring 3 and is fixed to the bottom plate by the second bolt 6. The shape of the upper baffle 4 matches the top contour of the sealing ring to ensure that it can closely cover and shield the non-spraying area.

[0019] When assembling the tooling body, first, place the bottom plate 7 on a stable workbench to ensure that the surface of the bottom plate is clean and free of debris. Place the sealing ring 3 accurately in the predetermined position on the bottom plate 7. The function of the sealing ring is to ensure a sealed environment inside the tooling and prevent the spraying material from leaking. Use the first bolt 2 and the nut 5 to preliminarily pre-tighten the inner baffle 1 on the bottom plate 7. In this step, it is necessary to pay attention to maintaining a certain gap between the inner baffle and the bottom plate to facilitate the subsequent smooth adjustment and installation of other components. Place the upper baffle 4 above the sealing ring 3 to ensure the correct positional relationship between the upper baffle and the inner baffle 1. The two together form a shielding area for protecting the non-spraying area. Use the second bolt 6 to tightly connect the upper baffle 4 to the bottom plate 7. In this step, it is necessary to ensure that all bolts are evenly tightened to ensure that all components are closely fitted and in the correct position, thus forming a stable tooling structure. After completing the tooling assembly, the spraying operation can be carried out. The tooling design can effectively shield the non-spraying area and only expose the part that needs to be sprayed, realizing precise spraying. At the same time, the structure and material selection of the tooling also ensure the stability and durability during the spraying process.

[0020] The above is only a specific application example of the present utility model and does not constitute any limitation to the protection scope of the present utility model. Any technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of the rights protection of the present utility model.
