在模具制造中,经常需要把工件一侧的孔位引渡到另一侧去加工,引孔时一般用高度尺划座标线取位。但有时这种方法却行不通,如工件没有基面或工件超大立起困难时。为此,我厂在制造汽车大梁模具时,制作了一种工具(如图示),较好地解决了这个问题。使用时,将顶针2对准原孔,旋紧螺母4,使本体 In the mold manufacturing, often need to work on one side of the hole extradite to the other side to go to the processing, when the hole is generally used to draw a high degree of alignment line. But sometimes this approach does not work, such as the workpiece does not have the base or large parts of the erection difficulties. To this end, I plant in the manufacture of automobile beam mold, the production of a tool (as shown), a better solution to this problem. Use, the thimble 2 aligned hole, tighten the nut 4, so that the body
