我厂使用的圆锥管螺纹丝锥ZG1/8″～2″(牙形角55°,平顶型),在制造时,中径的测量过去在工具显微镜上进行。定位、装卡繁琐,不易操作,所以,我们制作了1:16锥度量块,用外径千分尺采取三针测量法,简便易行。操作者只需按下表(见表)中M_理的值,对照实测结果,在加工中测量即可。 ZG锥管螺纹丝锥,在轴向截面上,牙形螺距标注方向与轴线平行,牙 The taper pipe taps ZG1 / 8 “~ 2” (55 ° angle, flat-top type) used in our factory were manufactured before the diameter measurement was performed on a tool microscope. Positioning, mounting card cumbersome, not easy to operate, so we made a 1:16 taper block, using an outer diameter micrometer to take three-pin measurement method, simple and easy. The operator simply press the table (see table) in the M_ value, the actual measurement results in processing can be measured. ZG taper pipe thread tap, in the axial cross-section, the tooth-shaped pitch pitch direction parallel to the axis, the teeth
