我厂承接了一批冷冻机气缸套加工任务,其大端尺寸如图1所示,经分析,1_0~(-0.04)mm,3_0~(-0.04)mm,4.5_0~(-0.048)mm三个尺寸都是以A面为基准,且尺寸精度较高。生产过程中检测比较困难。为此,我们设计了一种专用深度测量仪,如图2所示,经过使用(?)深受生产车间及检查人员的欢迎。 I plant to undertake a number of freezer cylinder liner processing tasks, the big-end size shown in Figure 1, the analysis, 1_0 ~ (-0.04) mm, 3_0 ~ (-0.04) mm, 4.5_0 ~ (-0.048) mm Three dimensions are based on the A side, and higher dimensional accuracy. Detection of the production process more difficult. To this end, we designed a dedicated depth gauge, as shown in Figure 2, through the use of (?) By the production workshop and inspectors welcome.
