一面两销定位方式的改进

Improvement of one side two pin positioning mode

以某减速箱体工艺为例,通过箱体底面两个Ф8mm锥孔,采用一面两孔定位方式来进行加工,该定位方式与传统一面两孔定位区别在于,其采用圆锥销及圆锥削边销,为了解决圆锥销竖直方向过定位问题,圆锥销及其削边销采用浮动定位方式。

This paper takes a deceleration box process as an example,through two holes and 8 cone holes in the bottom of the box,and uses a two hole positioning mode.The positioning method is different from the traditional two hole positioning.It uses conical pin and conical cutting edge pin.In order to solve the problem of the vertical orientation of the conical pin,the conical pin and its cutting edge are used.Floating location method.
