As is well known, a refrigerator compressor is an important component part of a refrigerator capable of running, a motor drives a crankshaft in a crank case to rotate, and the crankshaft drives a connecting rod to drive a piston to reciprocate in a cylinder body so as to compress a refrigerating medium.
The crankcase of the refrigerator compressor plays an important role in the working process, and almost all compressor parts are assembled by taking the crankcase as a matrix, but the crankcase has great processing difficulty due to various types and complex structures, and particularly, the crankcase is provided with an R groove and a silencing cavity. The R groove is mainly used for assembling a piston pin for connecting the piston and the connecting rod, and the silencing cavity is mainly used for reducing or eliminating noise generated in the working process of the crankcase, and plays an important role in the normal working process of the compressor. However, because the R groove and the silencing cavity have higher requirements on dimensional accuracy, and the crankcase has a complex structure, the processing difficulty of the R groove and the silencing cavity is higher, the qualification rate of finished products is lower, and particularly for some series of crankcases, the stator surface of the crankcase has only two stator legs, the contact surface is smaller, the clamping stability is poor, and the processing difficulty is further improved.
In the prior art, the crankcase processing of only two stator feet on the stator surface is clamped firmly in a manner of compressing the crankcase cylinder head and the cylinder tail at three points, and the clamping and fastening in the crankcase processing process can be realized to a certain extent, but after the stator is fixed in the manner, the stability in processing is extremely poor, when a cutter contacts a workpiece for milling processing, the workpiece tends to obviously move, a serious cutter-yielding phenomenon occurs, the size of the crankcase processing is unstable, the cutter can be greatly damaged, the processing cost of the crankcase is greatly improved, and the size and the position change of the workpiece are irregular at every time of movement, so that the processing qualification rate of the crankcase groove is greatly influenced. Although a manual auxiliary supporting mechanism is proposed in patent document CN 201210143605.7, it is matched with the guide sleeve by vertically arranging the ejector rod on the support to provide auxiliary support for the workpiece by the support column, although the above structure can meet the auxiliary support for the workpiece to be processed to a certain extent, for the processing of the crankcase, because the size of the crankcase is smaller, the space for providing vertical support from one side of the crankcase after the crankcase is fixed on the fixture is limited, the above auxiliary supporting mechanism cannot be effectively applied, and the bottom of the ejector rod of the above auxiliary supporting mechanism is placed on the spring, the activity is larger, and the height of the support column is controlled by adopting a manual adjustment mode, the adjustment precision is worse, and the support column has the risk of being forced to move downwards when the workpiece is processed, so that the processing plane is offset, so that the processing precision is reduced, and the above supporting mechanism needs to be manually reset after the workpiece processing is completed, which tends to cause further reduction of the processing efficiency.
