组合机床是由一些通用部件及少量专用部件组成的高效自动化或半自动化专用机床,可以完成钻孔、扩孔、铰孔、镗孔、攻丝、车削、铣削及精加工等多道工序。组合机床的控制系统多采用机械、液压、电气或气动相结合的控制方式,而电气环节控制起着中枢联接作用。本文对机械动力滑台的继电接触器控制系统进行了PC改造,将硬接线控制系统改造成PC软件控制,实现了电气自动化控制。 The combination machine is a highly efficient automated or semi-automatic machine tool consisting of a number of common parts and a few dedicated parts for drilling, reaming, reaming, boring, tapping, turning, milling and finishing processes. Combination of machine control systems and more use of mechanical, hydraulic, electrical or pneumatic combination of control methods, and electrical links play a central role in the connection. In this paper, the mechanical power slide contactor control system for the transformation of the PC, the hard-wired control system into PC software control, to achieve the electrical automation control.
