图示测量工具,由一把普通的内径弹簧卡钳和一个量程为25.4mm的千分表组成,可作为孔内O形环槽直径尺寸的快速测量工具,也可用于多台阶内孔或孔太深而万能量具伸不进去的零件测量。
The illustrated measuring tool, consisting of a conventional caliper caliper and a dial gauge measuring 25.4 mm, can be used as a quick measuring tool for measuring the diameter of an O-ring groove in a bore. It can also be used in multi-step boreholes or holes that are too deep Universal energy measurement can not extend into the parts.
