Compressor assembling equipment and assembling method

Abstract

The invention relates to the technical field of compressors, and discloses compressor assembly equipment which comprises a support, a compressor comprises an upper shell and a lower shell, a compressor core is installed in the lower shell, and laser welding is conducted after the upper shell and the lower shell are buckled. The industrial camera shoots images of the shells, if the gap between the shells is larger than a set value, the controller adjusts the pressure of the first pressure adjusting valve, the pressure of the second pressure adjusting valve and the pressure of the third pressure adjusting valve, the gap between the upper shell and the lower shell reaches the set value, and then welding is conducted. The laser welding device has the advantages that the pressure borne by the upper shell and the lower shell is controlled according to the size of the gap between the upper shell and the lower shell, the gap reaches a set value, air leakage is avoided after laser welding, and the air leakage rate is reduced.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor assembly device and an assembly method. Background technique [0002] The compressor is to raise the refrigerant from low pressure to high pressure to achieve the cooling effect. The shell of the fully enclosed refrigerator compressor is composed of an upper shell and a lower shell. The movement is installed in the shell. After the upper and lower parts are assembled, it needs to be welded , and then check whether the weld is leaking. [0003] In the prior art, in the compressor assembly line, after the upper casing and the lower casing of the compressor are installed, carbon dioxide shielded welding is used for welding, which requires filler wire, and the cost is relatively high; laser welding does not require welding wire, but if the upper and lower casings are assembled, the gap is If it is too large, there will be pores in the weld after welding and air leak...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, in the compressor assembly line, after the upper shell and the lower shell of the compressor are installed, carbon dioxide shielded welding is used for welding, which needs to be filled with welding wire, and the cost is high; laser welding does not require welding wire, but if the upper and lower shells are assembled. If it is too large, there will be air holes in the weld seam after welding, resulting in air leakage, and the pass rate is low, so it is necessary to repair the leaking compressor
