Problems solved by technology
The traditional spraying protection tooling mainly has the following disadvantages: 1. It is fixed by bolts and nuts, and it takes time to install and clamp. At the same time, because the spraying liquid is stained on the bolts and nuts, it is difficult to rotate the nuts during subsequent disassembly; 2. The bearing hole protection plate 1 and the bearing to be protected Hole A, brake casing hole protection plate 2 and the protected brake casing hole B are all sealed with cylindrical surfaces, resulting in serious material waste

Embodiment Construction
[0014] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0015] Such as figure 2 As shown: the wheel coating protection device in the embodiment is mainly composed of a bearing hole protection plate 1, a brake sleeve hole protection plate 2 and a detachable connection mechanism. The bearing hole protection plate 1 and the brake sleeve hole protection plate 2 can pass through The detachable connection mechanism is connected, and the outer circumferential surface of the bearing hole protection plate 1 and the bearing hole A is a tapered inclined surface with a small inside and a large outside, and the taper line seal is between the bearing hole protection plate 1 and the bearing hole A; The outer circumferential surface of the brake casing protective plate 2 and the brake casing B sealingly fit is a tapered inclined surface with a small inside and a large outside, and a tapered line seal between the brake casing prote...

The invention relates to a vehicle wheel coating shielding device which comprises a bearing hole shielding plate and a brake sleeve hole shielding plate. The bearing hole shielding plate and the brake sleeve hole shielding plate are connected through a detachable connecting mechanism. The vehicle wheel coating shielding device is characterized in that the outer circumferential face, in sealing fit with a bearing hole, of the bearing hole shielding plate is a taper inclined face with the interior smaller than the exterior, and the bearing hole shielding plate and the bearing hole are in taper linear sealing; and the outer circumferential face, in sealing fit with a brake sleeve hole, of the brake sleeve hole shielding plate is a taper inclined face with the interior smaller than the exterior, and the brake sleeve hole shielding plate and the brake sleeve hole are in taper linear sealing. The vehicle wheel coating shielding device is simple in structure, reasonable in design and convenient and fast to clamp and demount, and production efficiency can be greatly improved. Taper linear sealing is adopted in the sealing structures between the shielding plates and the corresponding holes, materials are greatly saved, and good economic benefits are achieved.
Description
technical field [0001] The invention relates to a wheel coating protection device, which is used for protecting a bearing hole and a brake sleeve hole when the wheel is sprayed, and belongs to the technical field of automobile parts processing and manufacturing. Background technique [0002] In the prior art, some gravity-cast aluminum alloy drum brake wheels need to be surface sprayed after the machining of the product is completed. Such as figure 1 As shown, since the bearing hole A and the brake bushing hole B on the wheel are the installation mating surfaces, it is strictly forbidden to spray the paint when spraying. For this reason, it is necessary to protect the bearing hole A and the brake sleeve when the wheel is sprayed. The traditional spraying protection tooling mainly has the following disadvantages: 1. It is fixed by bolts and nuts, and it takes time to install and clamp. At the same time, because the spraying liquid is stained on the bolts and nuts, it is dif...
