为东风内燃机车配套的活塞螺柱,以前用C618车床分两道工序,采用靠模仿形车削,人工装夹,效率低,质量不稳定。为此将C710—1半自动车床改装成气动控制的全自动专用螺柱仿形车床(不破坏原机床结构)。图1为已改装好的设备示意图。自动工作程序是:在料盘上放满一端打好中心孔的棒料,揿动行程 For the Dongfeng diesel locomotive supporting the piston stud, used to be divided into two processes with C618 lathe, the use of copy-shaped turning, manual clamping, low efficiency, unstable quality. For this purpose, the C710-1 semi-automatic lathe is retrofitted to a pneumatic, fully automatic, special stud copy lathe (without damaging the original machine structure). Figure 1 has been modified equipment schematic. Automatic work program is: fill the tray on the end of the center hole to lay the bar, move the trip
