外螺纹加工定位的问题的研究与解决方案

工业生产中经常会遇到使用手动螺纹加工的情形,对于内螺纹的加工预先进行底孔加工后,随后再使用丝锥进行内螺纹的加工,内螺纹加工时主要依靠丝锥的端部和底孔配合进行定位导向,而在外螺纹加工时,是使用板牙在外圆柱上进行螺纹加工,通常在圆柱的端部进行倒角,以方便板牙的定位和进刀。但是遇到硬度较高的材质,加工外螺纹的规格较大时,经常使套丝板牙的定位和入刀变的十分困难,经过研究发现,在有可靠导向装置的保障下可以有效的解决此类问题,本文将研究开发一种带导向的手动螺纹套丝工具,已解决目前工业生产的难题。

目前,螺纹加工的圆板牙及圆板牙架的标准有,公制 GB/T 970.1-2008标准规定了公制螺纹的圆板牙及板牙架的型式和尺寸。
