我厂生产2F65型制冷压缩机,阀板(图1)是机组中的重要零件之一。对其上环形槽深度测量深感不便。为此,我们设计、制造了简易专用检具(图2),其结构主要由导向测杆和检具体组成。其配合间隙最大公差为0.025 I plant 2F65-type refrigeration compressor, valve plate (Figure 1) is one of the important parts in the unit. Deep groove on the depth of its inconvenience. To this end, we designed and manufactured a simple special gages (Figure 2), the structure of which is mainly composed of the guide rod and seized body. The maximum clearance with the gap is 0.025
