Method for manufacturing compressor

Abstract

The invention discloses a method for manufacturing a compressor. The method includes the following steps that S1, a main shell body and a lower shell body are formed in a spinning mode or are connected into a whole in an electric resistance welding mode, so that a main shell body assembly is obtained; S2, a compressing mechanism is connected with a rotor so as to obtain a pump body assembly; S3, a stator and the pump body assembly obtained in the step S2 are located; S4, the stator and the pump body assembly located in the step S3 are fixed in the main shell body assembly obtained in the step S1; S5, an upper shell body is connected to the top of the main shell body. According to the method for manufacturing the compressor, the combined piece of the main shell body and the lower shell body are obtained through the metal spinning technology or the electric resistance welding machining technology, so that the technological manufacturability of the shell bodies is improved, the appearance of the shell bodies is good, and the leakage rate is low; meanwhile, the production cost of the shell bodies is lowered, the manufacturing difficulty is lowered, and the manufacturing efficiency is improved.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a manufacturing method of a compressor. Background technique [0002] It is pointed out in the related art that the shell of a compressor generally includes an upper shell, a main shell and a lower shell. One of the main structures and processes is to make a separate main shell and a lower shell. During the assembly process of the compressor , Welding by fusion welding, generally using mixed gas shielded welding, need to add welding wire and use shielding gas, the processing cost is high, and because there are many influencing factors in the welding process, the welding parameters fluctuate greatly, and it is easy to cause poor processing and welding Seam leakage problem; Another structure and process method is deep drawing process, which processes the main shell and the lower shell into an integrated shell. Although it can solve the problem of welding the main shell and th...
