The increasing awareness of environmental protection makes people have higher and higher requirements on energy consumption and efficiency of equipment, and the traditional processing method cannot meet the requirements of people on product performance.
The reason why the refrigerator can cool is that a refrigeration system (compressor) in the refrigerator performs work. The refrigerating principle of the compressor is that a refrigerating medium is compressed by moving a piston in the compressor, so that the refrigerating medium is switched between a gas state and a liquid state, and when the liquid refrigerating medium is converted into a gas state, a large amount of heat can be absorbed, and the aim of refrigerating the refrigerator is fulfilled. The piston is connected to the crankshaft by a connecting rod. After the compressor is powered on, the rotor in the compressor is rotated by the conversion between electricity and magnetism, the rotor is connected with the crankshaft in a pressure-volume matching manner, and the piston is driven by the connecting rod to move forwards and backwards to do work, so that the aim of refrigeration is fulfilled. The crankshaft is arranged in a crankshaft hole of the cylinder body, and the shaft shoulder surface is connected with the bearing surface of the cylinder body through a plane bearing.
The processing quality parameters of the crankshaft shoulder surface mainly comprise the perpendicularity of the crankshaft shoulder surface and the crankshaft, the planeness of the crankshaft shoulder surface and the smoothness of the crankshaft shoulder surface. Because the shaft shoulder surface of the crankshaft is small and is very close to the excircle of the crankshaft main shaft, the processing difficulty is very high. The traditional processing method is to grind the shaft shoulder surface of the crankshaft by using the grinding wheel plane of the cylindrical grinding machine. The crankshaft processed by the grinding mode has poor quality stability, poor finish of the shaft shoulder surface and incapability of ensuring verticality and planeness.
