Z3040摇臂钻床的PLC改造

摘  要
Z3040摇臂钻床是我国使用较多的钻床，是一般机械加工车间常用的机床。由于其控制系统采用继电器控制方式，电路接线复杂、触点多。长期使用后，故障率高，故障排查困难，常常影响企业的正常生产。因此对Z3040摇臂转床的PLC改造有特别重要的意义。PLC具有可靠性高，环境适应性强，使用方便，维护简单等优点。因此，利用PLC对摇臂钻床继电器电路进行设计，有助于提高设备的可靠性。本文分别对Z3040摇臂转床的主轴电动机的控制，摇臂的上升、下降以及主轴箱、立柱的松开和夹紧进行PLC改造。最后绘制出梯形图和I/O接口图。

Z3040 Rocker Switch To The Bed PLC Reconstruction

Abstract
Radial Drilling Machine Z3040 is China's use of more drilling, is commonly used in general machining machine tool shop.  Because of its control system uses relay control mode, circuit wiring complex, multi-touch.  Long-term use the failure rate is high, troubleshooting problems and often affect failure the normal production.  Therefore Z3040 rocker switch to the bed PLC transformation of special importance.  PLC has a high reliability, environmental adaptability, easy to use, easy maintenance and so on.  Therefore, the use of PLC relay circuit for radial drilling machine is designed to help improve equipment reliability.  In this paper, rocker switch on the Z3040 bed spindle motor control arm rise, decline and spindle boxes, columns of the release and clamping to PLC reconstruction.  Finally draw the ladder, and I / O interface map.
Key words: Z3040 Rocker Switch Beds;Electrical Control System;PLC Reconstruction
