一、前言在自动线或配置有上、下料机械手的高效自动机床上,对中型轴进行加工前(例如铣削花键槽、铣削长键槽及钻削径向盲孔等),首先要解决的问题是工件必须处于正确的定位。工件从输送状态转入待加工状态,产生位移是一个普遍现象,而且每一个工件的位移量不相同。这就要求我们设计一种回转装置,将工件逐个纠正到正确的定位位置。 I. INTRODUCTION The most important problem to be solved before automatic machining of automatic line or equipped with upper and lower robots is to process the medium-sized shaft (such as milling spline grooves, milling long keyways and drilling radial blind holes) The workpiece must be positioned correctly. Workpiece from the delivery state into the state to be processed, the displacement is a common phenomenon, and the displacement of each workpiece is not the same. This requires us to design a slewing device, the workpiece one by one to correct the correct location.
