Method for processing output shaft rear end closure of automobile parts

Abstract

The invention discloses a method for processing an output shaft rear end closure of automobile parts, which comprises the following steps: machining the end faces of a big end and a small end through rough lathing and machining retainers in the inner hole and the big end while ensuring flatness; drilling holes, namely, drilling, expanding and reaming the holes according to the requirements of the drawing and reaming two expanded holes; abrading planes, namely, abrading a big plane and a width to the dimensions shown in the drawing by taking a small end plane as a reference; finely lathing, namely, positioning by the two reamed inner holes and latching the retainer in the big end, a length, the inner hole of the small end and end face to the dimensions shown in the drawing by taking a large end plane as a reference; boring a hole, namely, positioning by the retainer in the big end and a reamed hole and boring an inner hole in a line of the dimension shown in the drawing under the big end by taking the large end plane as a reference; tapping threads, namely, tightly pressing the workpiece to tap threads according to the requirements of the drawing; doing tests by using corresponding measuring tools; and packaging the output shaft rear end closure after deburring and oil application and warehousing the output shaft rear end closure. The method radically guarantees the planeness, parallelism, face runout, position degree and high quality of the product, reduces cost and greatly improves economic benefits.

Description

Technical field: [0001] The invention relates to auto parts, in particular to a processing method for the rear end cover of an output shaft of an auto part. Background technique: [0002] At present, the flatness, parallelism, runout and position of the rear end cover of the output shaft of auto parts cannot be guaranteed, resulting in poor product quality and great losses to enterprises and users. Invention content: [0003] The purpose of the present invention is to provide a processing method for the rear end cover of the output shaft of the auto parts, which can well overcome the problems of the above products. The purpose of the present invention is achieved in this way, the processing method of the rear end cover of the output shaft of the auto parts is characterized in that: rough turning: three claws clamp the large outer circle of the blank, the end face of the small end of the turning, the width of the part is controlled, the inner hole of the small end of the tu...
