In recent years, with the popularity of energy conservation and emission reduction and low-carbon concept, China's new energy vehicle industry has also ushered in a boom of research and development, mass production and sales. With the strong promotion of national policies, domestic automobile manufacturers have launched new energy vehicle projects, and successively launched pure electric vehicles to the market. Aluminum alloy water-cooled motor housing is widely used as a supporting product of new energy vehicles.
The research and development of aluminum alloy motor housing has successfully replaced the die casting aluminum motor housing. It solves the problems of poor density of casting aluminum alloy motor housing materials, easy to cause casting defects such as pores and sand holes, and solves the problems of poor density of casting aluminum alloy motor housing, poor surface casting roughness, which seriously affects the corrosion resistance and corrosion resistance of the body, and at the same time, the processing amount will increase.
However, due to the poor concentricity of aluminum housing motor case and end cover, the use of aluminum alloy motor case is restricted by the large noise of aluminum housing motor. This paper briefly analyzes the causes of the noise of the motor with aluminum alloy motor housing, and according to the processing method of aluminum motor housing, designs a processing tool for aluminum alloy motor housing, which successfully solves the problem of large noise of the motor with aluminum alloy motor housing
