[0002] The air conditioner compressor compresses and drives the refrigerant in the air conditioner's refrigerant circuit. Typically installed in the outdoor unit, the compressor draws refrigerant from a low-pressure area, compresses it, and then sends it to a high-pressure area for cooling and condensation. Heat is dissipated into the air through the heat sink, and the refrigerant changes from a gas to a liquid, increasing its pressure.

The application range of grinding equipment is relatively wide. The grinding device usually operates by sending the polished coolant into the refrigeration device. It is usually composed of a cylinder body, a motor, an air-conditioning clutch adjustment plate, a planetary plate, an electromagnetic coil, a cooling bearing, an intake valve plate, a suction cup, and a fixed bevel gear. The electromagnetic coil is driven by a motor installed on the outside to operate, and then the fixed bevel gear in the middle is driven to rotate, thereby driving the planetary plate above to operate, and cooperated with the cooling bearing to complete the processing of the coolant in the cooling device, thereby completing the grinding operation of the air-conditioning compressor.

[0004] In the current existing technology, the air-conditioning compressor grinding device on the market is usually operated by a motor installed on the outside, which drives the electromagnetic coil to work, and then drives the fixed bevel gear in the middle to rotate, thereby driving the planetary disk above to work, and cooperates with the cooling bearing to complete the processing of the coolant in the cooling device, thereby completing the grinding operation of the air-conditioning compressor. However, during the grinding process of the air-conditioning compressor, the piston rod inside the compressor will make noise due to its movement during operation, and the load on the upper inclined plate is relatively large during long-term operation, and there are certain safety hazards. Therefore, in response to the above problems, an air-conditioning compressor end plate air duct inner wall grinding device is proposed. Utility Model Content
