Abstract

The invention relates to an automobile air conditioner compressor piston hemisphere matching method, which belongs to the technical field of piston hemisphere matching, and comprises the following steps: S1, detecting the distance between two ball sockets of a piston base to obtain a ball socket distance value, and marking the ball socket distance value as L1; S2, detecting the thickness of the swash plate and recording the thickness value as L2; S3, calculating a reference value L3 of the hemisphere gap according to a set numerical interval of the hemisphere gap, wherein L3 = (hemisphere gapupper limit + hemisphere gap lower limit) / 2; S4, calculating the hemisphere size LX = (L1-L2-L3) / 2 according to the numerical values obtained in the steps S1-S3; S5, dividing each gear of the hemisphere size into three value areas, namely a low value area, a medium value area and a high value area; and S6, the value area of the hemisphere size LX obtained in the step S4 in the hemisphere size gearis judged, and the technical problem that in the prior art, the piston hemisphere matching precision is low, and consequently the piston assembling error is large is solved.

Description

technical field [0001] The invention relates to a method for matching piston hemispheres of an automobile air-conditioning compressor, and belongs to the technical field of piston hemisphere matching. Background technique [0002] Automobile air-conditioning compressor is the heart of automobile air-conditioning refrigeration system, which plays the role of compressing and transporting refrigerant vapor. According to the different internal structures, compressors are divided into many types. Among them, the swash plate compressor relies on the rotary motion of the swash plate inclined to the rotating shaft to drive the piston or piston rod to reciprocate to achieve gas compression, which is widely used. Among them, the fit gap between the piston ball socket of the compressor piston, the hemisphere and the swash plate plays an extremely important role in the performance of the compressor. A suitable hemisphere gap can effectively reduce the working noise of the compressor and...
