我厂对使用中的量规(主要是塞规和卡规),都是按固定周期、批量周期或班检蜡封进行检定,但都存在着管理困难、送检频繁和重复劳动等缺点。我们试验了一种用电解刻线深度控制量规磨损极限尺寸的检定方法,经过试用效果良好。如塞规的实际尺寸为d,磨损极限尺寸为d′,在塞规工作面平行于轴线方向上,用电解法刻上两条长4mm:宽0.14mm的线,其深度为h,则 h=(d-d′)/2 (1) 在使用中塞规逐渐磨损,则刻线深度也越磨越浅,当刻线磨损至看不清时,塞规的实际尺寸已到磨损极限尺寸,则停止使用,送检定
I plant on the use of the gauge (mainly plug gauge and gauge) are based on fixed cycle, batch inspection or wax seal class test, but there are management difficulties, frequent inspection and duplication of labor and other shortcomings. We experimented with a test method of depth-control gauge wear limit size using electrolytic scribing, good results after trial. If the actual size of the plug gauge d, wear limit size d ', in the plug gauge face parallel to the axis direction, engraved by electrolysis of two long 4mm: 0.14mm wide line, the depth of h, h = (dd ') / 2 (1) In the use of Cypriot gradual wear, the depth of the line is also more grinding shallow, when the engraved lines wear to see the clear, the actual size of the gauge has reached the wear limit size, then Stop using, sending test
