Automobile hub and machining process thereof

Abstract

The invention discloses an automobile hub. The automobile hub comprises an automobile hub body, a hub shaft is arranged in the middle of the interior of the automobile hub body, a stainless steel check ring is welded to the periphery of the exterior of the inner side of the hub shaft, bolt holes are distributed in the periphery of the hub shaft, and reinforcing ribs are welded to the side of the automobile hub body. A tire bead seat is arranged on the periphery of the outer portion of the automobile hub body, rhombic spokes are distributed between the automobile hub body and the hub shaft in a welded mode, fork-shaped spokes are welded between the rhombic spokes, a rim reinforcing device is distributed on the outer portion of the automobile hub body in a welded mode, and convex holes are distributed in the two sides of the rim reinforcing device. The surface of the automobile hub body is coated with a protective layer through a painting device. According to the automobile hub, the automobile hub body can be circularly machined, the working efficiency of automobile hub body painting is greatly improved, and the production efficiency of the automobile hub body is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a wheel hub processing technology, in particular to an automobile wheel hub and the wheel hub processing technology. Background technique [0002] The wheel hub (Car Rim) is the part where the axle is installed in the center of the wheel, which is often referred to as the "rim" or "steel ring". The hub is easily stained with dirt. If it is not cleaned for a long time, it may be corroded and deformed, resulting in a safety hazard. Therefore, special attention should be paid to the maintenance of the hub. [0003] Comparative document CN101940993B The present invention discloses a spraying process for automobile wheels, which includes the following steps: 1) block the valve hole of the automobile wheel with a blocking tool, then place the automobile wheel on a pallet, and then use positioning pins to match the automobile wheel itself The PCD hole of the car is positioned on the...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, spraying is usually used to paint the wheel hub, but the spraying method has the problem that the paint surface on the wheel hub surface is not uniform enough, and is usually sprayed one by one according to the conveying direction, and the efficiency is relatively low.
