[0002] The compressor is an impulsive fluid machine that boosts low-pressure gas to high-pressure gas. It sucks low-temperature and low-pressure refrigerant gas from the intake pipe, compresses it by driving the piston through the rotation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle, thereby realizing the refrigeration cycle. The compressor end cover is an important part of the air-conditioning compressor. There are many processes in the processing of the compressor end cover. One of the processing processes is drilling and tapping the compressor end cover. At present, the end cover is usually fixed with a splint, and then the splint is fixed with screws, which makes disassembly more cumbersome.
