Manufacturing process of high-strength aluminum alloy automobile hub

Abstract

The invention provides a manufacturing process of a high-strength aluminum alloy automobile hub. The manufacturing process comprises a clamping and rotating mechanism, an inner grinding mechanism, supporting mechanisms and a bottom plate, the inner grinding mechanism is arranged over the bottom plate and installed on the clamping and rotating mechanism, the clamping and rotating mechanism is installed on the bottom plate, and the supporting mechanisms are arranged on the outer side of the clamping and rotating mechanism. The supporting mechanisms are symmetrically mounted on the clamping and rotating mechanism. The following problems are solved, according to existing automobile hub polishing equipment, a hub is usually arranged externally for polishing, the inner side and the outer side cannot be synchronously polished, the hub is usually fixedly arranged during polishing, the polishing efficiency is poor, the polishing consistency of the inner side and the outer side of the hub cannot be subjected to uniform fine treatment, the use requirement is difficult to meet, and automobile hubs of different sizes cannot be polished, as a result, the that refined polishing treatment has limitation and the like.

Description

technical field [0001] The invention relates to the technical field of polishing and grinding technology of automobile wheel hubs, in particular to a manufacturing process of high-strength aluminum alloy automobile wheel hubs. Background technique [0002] High-strength aluminum alloy car wheel, also known as rim, is the barrel-shaped part of the inner profile of the tire that is used to support the tire, and the center is assembled on the shaft; common car wheels include steel wheels and aluminum alloy wheels; aluminum alloy wheels are Its light weight, fast heat dissipation, good shock absorption performance, long tire life, high strength, not easy to deform, safe and reliable, beautiful appearance, colorful patterns, accurate size, good balance, and easy manufacturing, etc., stand out in the automotive industry. Huge potential for development; [0003] High-strength aluminum alloy car wheels are generally cast in one piece during the manufacturing process. After casting,...

AI Technical Summary

Problems solved by technology

[0003] High-strength aluminum alloy car wheels are generally cast in one piece during the manufacturing process. After casting, they need to be processed before they can be used. After rough machining, there will be some rust and burrs on the surface of the car wheel. The surface of the wheel needs to be refined. Polishing and grinding treatment, the existing wheel hub grinding equipment usually grinds the wheel hub externally, and the inner and outer sides cannot be polished simultaneously, and the wheel hub is usually fixed in a fixed setting, which makes the grinding efficiency poor and the grinding consistency of the inner and outer sides of the wheel hub cannot be achieved. Uniform and refined treatment is difficult to meet the requirements of use, and the grinding treatment cannot be carried out for different sizes of automobile wheels, so that the fine grinding treatment has limitations; for this reason, the present invention provides a high-strength aluminum alloy automobile wheel hub manufacturing process
