轴类零件键槽对称度快速检测专用量具

Special Measuring Tool for Rapid Detection of Symmetry Keyway

测量轴类零件键槽对称度时,在游标卡尺的游标外测量爪内侧加装一把测量尺,使外测量爪一长一短,在不破坏原游标卡尺精度的情况下组装出的结构简单、精度高、拆装方便、测量快速的这种测量工具,解决了轴键槽对称度无法直接测量的难题,提高了工效。

When measuring shaft keyway symmetry with a measuring scale on the inner side of the vernier caliper claws, the outer measuring claws are one long and one short. This measurement tool structure is assembled which does not damage the original ver- nier caliper accuracy with the functions of simple, high precision, convenient assembly and disassembly, rapid measurement, and solves the problem of shaft keyway symmetry which cannot be measured directly, so as to improve work efficiency.
