Abstract

The invention provides a method for processing a reducing gear front shell of automobile parts, which comprises the following steps: according to the requirements of a drawing, roughly and finely lathing the end face of a small end and the smallest outer circle, lathing a large plane and a retainer, boring an inner hole, lathing feet R and cutting grooves; finely boring two smallest inner holes while ensuring the coaxiality of the two holes is no more than phi0.04; drilling nine phi12.5 holes and four phi6.7 holes on a central line shown in the drawing; milling a left side small plane parallel to a big plane and roughly and finely boring inner holes on the small plane; milling a small boss plane on an upper right part and rilling a phi22.5 through hole; reaming a phi26 holes on in the nine phi12.5 holes; tapping threads; doing tests by using corresponding measuring tools and apparatuses; and doing a leakage test by applying a pressure of 8 bar without leakage. The method fully guarantees the product in hole-to-hole center line parallelism and coaxiality as well as pressure leakage and high quality, prolongs the service life of the product and meets the requirement for the rapid development of the automobile industry.

Description

technology field;

[0001] The invention relates to auto parts, in particular to a processing method for the front casing of the final reducer of the auto parts. Background technique:

[0002] The current front housing products of the main reducer for auto parts cannot be guaranteed in terms of parallelism and coaxiality between the hole and the center line of the hole and the pressurized leakage of the product. The product quality is poor and the service life is low, which seriously affects the automobile. The needs of the rapid development of the industry. Invention content:

[0003] The purpose of the present invention is to provide a processing method for the front casing of the main reducer of the auto parts, which can well overcome the defects of the above products. The purpose of the present invention is achieved in this way, the processing method of the front housing of the main reducer of the auto parts is characterized in that: rough turning: the outer circle of t...
