Abstract

The invention provides a method for machining a car differential shell. On the basis of ensuring the machining precision of a product, the development time of the product is shortened, the equipment investment is reduced, and machining of the car differential shell is realized by using general equipment. The invention adopts the technical scheme that the method for machining the car differential shell comprises the following steps of: (1) roughly turning an end face, an external circle and an axial inner hole at one end of the car differential shell on a numerical control lathe, and chamfering; (2) roughly turning an end face, an external circle, an axial inner hole and an annular groove at the other end of the car differential shell on the numerical control lathe, and chamfering; (3) finely turning the external circle in the step (1) and the external circle and the annular groove in the step (2) on the numerical control lathe; (4) finely machining the axial inner holes in the step (1) and the step (2) on a machining center; and (5) finely machining a cavity spherical surface on the machining center.

Description

technical field [0001] The invention relates to a processing method for a car differential case. Background technique [0002] The car differential housing is an important part of the car transmission system. The characteristic of this product is that the axial hole and the spherical surface of the inner cavity require high precision, and the spherical surface is difficult to process due to product structure restrictions. The spherical surface of the inner cavity and the hole are closely connected with other parts of the transmission system. The machining precision of these parts directly affects the uniformity of the transmission fit clearance, which is directly related to the performance of the vehicle. [0003] At present, the processing technology of foreign and domestic car differential housings mainly uses special machine tools with special telescopic tools for production and processing, and is generally equipped with automatic lines. Its advantages are: relatively h...
