某种湿式气缸套凸台的高度(见图1),为1.6±0.05.由于尺寸比较小,检测凸台的范围也窄小,用样板检测,误判比较多,用深度尺检测也很麻烦.为此,我们设计了专用检具(见图2).表座1有两处与气缸套内孔相配合,以保证百分表的触杆始终能测到气缸套端面上.表座的下面与气缸套凸台面接触,螺钉固定百分表. The height of a wet cylinder liner boss (see Figure 1) is 1.6 ± 0.05. Due to the small size, the range of the detection boss is also narrow, with the template test, misjudgment is more, with the depth of foot detection is also very troublesome To this end, we designed a special gage (see Figure 2). Table 1 has two seats with the cylinder bore to match, to ensure that the dial indicator rod can always be measured on the cylinder liner end surface. The following contact with the cylinder liner boss table, screws fixed dial indicator.
