Embodiment Construction

[0006] Below in conjunction with accompanying drawing, the present invention will be further described;

[0007] In the figure, the processing method of the front shell of the main reducer of the auto parts is characterized by: rough turning: the outer circle of the small end is aligned with the inner hole of the big end, and the end face of the small end and the minimum outer circle are turned to the length shown in the figure, Boring the smallest through hole; Rough turning: reverse clamping and boring the inner hole, turning the large plane and buckle, leaving a margin for fine turning; finishing turning: reverse clamping and boring the inner hole, turning the large plane and buckle to the size shown in the figure; Turn the inner cavity of the rough blank with a slope of 2° to the size shown in the picture; leave a margin for boring the inner hole, chamfer the R and the hole, cut the groove to the size shown in the picture; finish turning, put on the clamp, turn the small en...

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...
