Manufacturing and machining method for new energy automobile alloy hub

Abstract

The invention relates to a manufacturing and machining method for a new energy automobile alloy hub. The method mainly comprises the following steps of hub placing-in, hub clamping, auxiliary clamping, polishing treatment and the like, and a used machining machine comprises a fixed base, a placing table, limiting grooves, mounting bottom plates and clamping devices. The placing table is installedin the middle of the upper end of the fixed base, the limiting grooves are symmetrically formed at the front side and the rear side of the upper end of the fixed base, the mounting bottom plates are symmetrically arranged at the left sides and the right sides of the limiting grooves in a sliding manner, and the clamping devices are installed on the mounting bottom plates at the left sides of the limiting grooves. The problems that according to a traditional automobile alloy hub manufacturing and machining method, when manual handheld grinding equipment is used for grinding, a grinding mechanism is difficult to attach to the surface of a hub, so that the grinding and polishing effect of the partial surface of the hub is poor, a common hub clamping mechanism can block the grinding area of the hub, unstable clamping is likely to happen, and the grinding effect is not uniform are solved.

Description

technical field [0001] The invention relates to the technical field of wheel hub processing, in particular to a method for manufacturing and processing an alloy wheel hub of a new energy vehicle. Background technique [0002] Automobile hub is an important part of auto parts. With the growth of China's auto parts industry, the demand for auto hub is also increasing. Automobile hub is the part where the axle is installed in the center of the wheel, and it is easy to be stained with dirt. If it is not cleaned for a long time, it may be corroded and deformed, resulting in potential safety hazards. The wheels on the market can be divided into steel wheels and alloy wheels according to their materials. Alloy wheels are lighter in weight, have small inertial resistance, high manufacturing precision, small deformation during high-speed rotation, and small inertial resistance, which is conducive to improving the straight-line driving of the car. performance, reduce tire rolling res...

Problems solved by technology

[0005] The invention can solve the traditional manufacturing and processing method of automobile alloy wheels. Usually, the method of integrated casting is used to make automobile alloy wheels. After the alloy wheels are formed, burrs will occur, which will affect the appearance and quality of the alloy wheels, and because the shape of the alloy wheels is irregular , when manual hand-held grinding equipment is used for grinding, the grinding mechanism is difficult to fit tightly on the alloy wheel hub for grinding, resulting in poor grinding and polishing effect on the surface of the alloy wheel hub. The alloy wheel needs to be clamped, and the ordinary clamping mechanism will block the grinding area of ​​the alloy wheel, and when the wheel rotates, it is prone to unstable clamping, which makes it difficult to polish part of the outer surface and requires manual reprocessing. It will cause inconsistency in the grinding effect, affect the fit between the alloy wheel and the tire, and the appearance of the alloy wheel.
