Method for processing range gear air cylinder of automobile parts

Abstract

The invention provides a method for processing a range gear air cylinder of automobile parts, which comprises the following steps: according to the dimensions required by a drawing, lathing the end face of a left end, an outer circle and a length, boring a big inner hole and a depth, and cutting an inner groove; positioning by using the inner hole in the left end, and drilling four phi11 through holes, two phi8 through holes and a phi16.5 through hole according to the requirements of the drawing; performing milling according the requirements of the drawing; reaming four phi24 counter bores which are two millimeters deep on the four phi11 through holes; reaming two phi12.5 counter bores which are 15 millimeters deep on the two phi8 through holes and chamfering the two counter bores; performing tapping according to the requirements of the drawing; doing tests by using corresponding measuring tools; doing a gas test by mounting a workpiece on a special clamp and fixedly sealing a contact part; and doing a leakage test of the big hole in the left end and the two phi8 holes by applying a pressure of 8 bar and preventing leakage. The method prevents the air leakage of the air cylinder, ensures geometric tolerance and positioning tolerance, greatly improves product quality, creates benefits for enterprises and meets living needs of people.

Description

Technical field: [0001] The invention relates to auto parts, in particular to a processing method for range gear cylinders of auto parts. Background technique: [0002] At present, there are air leakage and unguaranteed position in the range of auto parts cylinders. The work efficiency is low and the product quality is poor, which brings great losses to enterprises and inconveniences to people's lives. Invention content: [0003] The object of the present invention is to provide a processing method for the range gear cylinder of auto parts, which can well overcome the existing defects of the above products. The object of the present invention is achieved in this way. The processing method of the range gear cylinder of auto parts is characterized in that: car: clamp the right end, position with the outer circle of the blank, the end face and outer circle of the left end of the car, and the length to the size shown in the figure, and bore large and small Inner hole and dept...
