[0023] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0024] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0025] like Figure 1-4 As shown, a wheel hub painting protective fixture is provided with a painting base carrier 1, a central protective body 2, and a protective disc 3. The central protective body 2 is set on the painting base carrier 1. The protective disc 3 has a mounting hole 31 in the middle and is fitted onto the central protective body 2. A protective ring 32 is provided around the edge of the protective disc 3. The protective ring 32 is located on the side away from the painting base carrier 1.
[0026] Specifically, the painting base carrier 1 serves as the support platform for the entire tooling. The central protective body 2 is mounted on the painting base carrier 1, and its design shape matches the center hole of the wheel hub. It is inserted into the center of the wheel hub to prevent paint from entering through the drainage groove 100 in the center of the wheel hub. The protective disc 3 is fitted onto the central protective body 2 through the central mounting hole 31 to cover the mounting surface of the wheel hub. The protective ring 32 is located around the edge of the protective disc 3, on the side away from the painting base carrier 1, that is, the side facing the mounting surface of the wheel hub, so that the protective ring 32 can be directly fitted onto the mounting surface, especially covering the drainage groove 100. During the painting process, paint will splatter onto various parts of the wheel hub. Due to the presence of the protective ring 32, it can effectively prevent paint from entering the mounting surface through the drainage groove 100 or gaps. At the same time, the cooperation between the central protective body 2 and the protective ring 32 forms a complete protective system, ensuring that both ends of the drainage groove 100 are effectively blocked, preventing paint penetration. In use, the painting base carrier 1, the central protective body 2, and the protective disc 3 are assembled. The central protective body 2 is inserted into the central hole of the wheel hub to be painted. At this time, the protective disc 3 and its protective ring 32 are tightly fitted onto the mounting plate of the wheel hub. Due to the protective effect of the protective disc 3 and the protective ring 32, paint cannot enter the mounting plate surface or the drainage groove 100. By setting the protective ring 32, it is placed on the outside of the mounting plate surface, especially covering the drainage groove 100, preventing paint from entering the mounting plate surface through the drainage groove 100 during the painting process, thus avoiding paint contamination. The protective ring 32 also enhances the sealing between the protective disc 3 and the wheel hub mounting plate surface, making them fit tightly and preventing paint from seeping in. The central protective body 2, inserted into the central hole of the wheel hub, together with the protective ring 32, forms a barrier at both ends of the drainage groove 100, achieving double protection and further improving the protective effect.
[0027] like Figure 2As shown, the bottom of the central protective body 2 is provided with a positioning groove 21, and the protective plate 3 is locked in the positioning groove 21.
[0028] Specifically, after the protective disc 3 is engaged in the positioning groove 21, the tight fit between the positioning groove 21 and the mounting hole 31 restricts the vertical movement of the protective disc 3, thereby ensuring that the depth of the central protective body 2 inserted into the center hole of the wheel hub is constant, and the length of the exposed part of the central protective body 2 is constant, ensuring that its insertion depth into the center hole of the wheel hub is consistent, and avoiding coating defects caused by inconsistent insertion depth. After the painting is completed, due to the tight fit between the positioning groove 21 and the protective disc 3, the protective disc 3 can be easily pulled out of the center hole of the wheel hub without being difficult to remove due to jamming or deformation.
[0029] like Figure 2 , 3 As shown, the central protective body 2 has a frustum-shaped end.
[0030] Specifically, due to its frustum-shaped design, the protective disc 3 can be easily placed on the central protective body 2, thus enabling rapid installation.
[0031] like Figure 2 , 3 As shown in Figure 4, the painting base carrier 1 includes a support column 11, a support plate 12 is provided at the top of the support column 11, and the central protective body 2 is provided at the center of the support plate 12.
[0032] Specifically, the painting base carrier 1 mainly consists of a support column 11 and a support plate 12. The support plate 12 is located at the top of the support column 11 and is used to support the central protective body 2 and the protective plate 3. When the protective plate 3 is placed on the central protective body 2, the support plate 12 not only provides a stable support surface for the protective plate 3, but also ensures a tight fit between the protective plate 3 and the wheel hub mounting plate surface through its flat surface, thereby avoiding leakage and defects during the painting process and improving the painting quality.
[0033] like Figure 2 , 3 As shown, the central protective body 2 and the protective disc 3 are made of high-temperature resistant rubber or high-temperature resistant silicone flexible materials.
[0034] Specifically, the high-temperature resistant rubber and silicone flexible materials can undergo certain deformation when subjected to external forces, thereby absorbing and dispersing stress, protecting the wheel hub and tooling from damage, and improving the sealing performance when the wheel hub and tooling are in contact, preventing the paint from entering from the gap between the tooling and the wheel hub, thus ensuring the quality and effect of the coating, and the high temperature resistance prepares the material for the subsequent baking process.
[0035] like Figure 2 As shown, the central protective body 2 is fixedly mounted on the support plate 12 by bolt assembly.
[0036] Specifically, the bolt passes through the reserved hole on the central protective body 2 and aligns with the screw hole below the support plate 12. The bolt assembly is used to fix it, ensuring that the central protective body 2 always remains in a fixed position during the painting process. The connection method of the bolt assembly can adapt to different types and sizes of central protective bodies 2 and support plates 12, improving the flexibility and applicability of the tooling.
[0037] like Figure 2 As shown, the support plate 12 is made of metal.
[0038] Specifically, the support disc 12 is made of metal, such as stainless steel or aluminum alloy. When the support disc 12 is driven to rotate, its rotational force is transmitted to the protective disc 3 through the contact surface. Since the protective disc 3 is tightly fitted to the wheel hub, the wheel hub will also rotate. The rotation of the wheel hub helps the paint to be evenly distributed on the surface of the wheel hub.
[0039] The beneficial effects of this application compared with the prior art are as follows:
[0040] This application discloses a painting protective fixture for wheel hubs, comprising a painting base carrier 1, a central protective body 2, and a protective disc 3. The central protective body 2 is mounted on the painting base carrier 1. The protective disc 3 has a mounting hole 31 in the center and is fitted onto the central protective body 2. A protective ring 32 is provided around the edge of the protective disc 3, located on the side away from the painting base carrier 1. By setting the protective ring 32, it fits over the outer side of the mounting disc surface, specifically covering the drainage groove 100, preventing paint from entering the mounting disc surface through the drainage groove 100 during the painting process, thus avoiding paint contamination. The protective ring 32 also enhances the sealing between the protective disc 3 and the wheel hub mounting disc surface, ensuring a tight fit and preventing paint seepage. The central protective body 2 is inserted into the central hole of the wheel hub, forming a barrier at both ends of the drainage groove 100 together with the protective ring 32, achieving double protection and further improving the protective effect.
