键槽深度塞规结构改进

键槽深度塞规按照以往的结构尺寸进行加工，易产生热处理变形，且磨削出的圆弧尺寸、表面粗糙度及通、止端尺寸难达到图纸要求，存在很高的废品率。针对这一问题，在保证使用要求的前提下改进其结构尺寸，提高了工艺性，降低了加工难度；既减少了成本，又达到了尺寸精度要求；很好地控制了此类量具的加工质量。

Structure Improvement for Spline Depth Plug Gage

Machining spine depth plug gage based on previous structure size often caused heat treatment deformation with difficulty of satisfying the drawing requirements of arc size,surface roughness go and no go size,which resulted in high reject percentage.Aiming at this problem,structure size was modified on the premise of ensuring operating requirement,as a result,easy machining process can be obtained with lower costs and good size accuracy,as well as good product quality.
