Processing method for automobile compressor rear cover

Abstract

The invention relates to a processing method for an automobile compressor rear cover, comprising the following steps of: designing a cutter; arranging a first cutter point, a second cutter point, a third cutter point, a fourth cutter point and a fifth cutter point which correspond to the slot bottom of the rear cover on the cutter; during processing, naturally forming a built-up edge at the right-angle part of the cutter to generate a chamfer of R0.3-R0.5 at the corresponding part of the rear cover; and when the built-up edge reaches a certain size, naturally dropping the built-up edge due to a cutting force, and then forming a new built-up edge. The invention has the advantages that the exhaust port of the processed rear cover is molded in one step so that the processing operation is convenient and the efficiency is high; moreover, the product quality is stable.

Description

technical field [0001] The invention relates to a processing method for the rear cover of an automobile compressor, in particular to a processing method of the type of sealing groove for an intubation pipe in the rear cover and the external thread connection type of the intubation pipe. Background technique [0002] Depend on figure 1 It can be seen that the rear cover of the automobile compressor (type 5H14) needs to be processed at the suction and exhaust ports. Marks 1, 2, 3, 4 and 5 in the back cover have higher requirements on the ring groove, inner hole and sealing surface, and the chamfering range of the sealing part is required to be small. [0003] Most of the processing methods in the prior art are processed by numerical control equipment, resulting in low processing efficiency and high processing cost. [0004] In the processing of such products, forming tools are also used in the prior art to try to solve the above problems, but due to the complexity of setting...

AI Technical Summary

Problems solved by technology

[0003] Most of the processing methods in the prior art are processed by numerical control equipment, which makes the processing efficiency low and the processing cost high

[0004] In the processing of such products, the existing technology also uses forming tools to try to solve the above problems, but due to the complexity of setting tools and the high cost of tools, especially the chamfering of the bottom of the tool groove cannot be processed, one-time forming processing cannot be realized.
