ABSTRACT

In PLC technology application, electrical engineer are no longer spend too many times on the hardware, they can only considered that the control push-button or the examination sensor connection in the PLC entrance point, and than they will be linked with contactor or the relay in the point outputing to control the high efficiency the starting outfit through the PLC internal treatment. The output of low-power devices can be connected directly to it.

With the rapid development of the automation technology, computer technology and network communication technology, the PLC function increases day by day. It is not only able to control the stand-alone, but also realize much machine controlling. At the same time as the PLC technology development, PLC has played a very important role in the field of automation technology. Due to many functions of PLC are better than relay so that the PLC gradually replace the relay. This enabled the automated control of PLC have the further development, it is more convenient, no matter for the operation, the service, maintains or line's simplification. It's merit even more prominent.

This article based on the merits of the PLC on T68 boring machine to carry out electrical lines transformation.'s Original machine tool operation the same way, the machine's main circuit unchanged, so that the machine control circuit simplifies the machine to reduce the failure rate. Was first proposed to improve the circuit The overall idea of the design of the PLC ladder and wiring diagram, a key part of the analysis of the circuit debugging process.

前言

可编程控制器(PLC)是一种为工业机械控制所设计的专用微型计算机,在各种自动控制系统中有着广泛的应用。它是在继电器控制和计算机控制基础上开发的产品,逐渐发展成为以微处理器为核心,把自动化技术、计算机技术,通信技术融为一体的新型工业自动控制装置。

随着技术的发展,可编程程序控制器(PLC)的控制功能不断增强,还可以进行算术运算,模拟量控制、顺序控制、定时、计数等,并通过数字、模拟的输入、输出控制各种类型的机械生产过程。众所周知,在现代化工业生产中机床母机是不可缺少的重要组成部分,我们国家现在在机床技术方面还一直比较落后,自动化程度也较低。主要表现在大部分工厂里的机床还是老式传统的机床,电气接线极其复杂、排故也相当困难,同时设备的投资与维修的费用也消耗很大。可编程控制技术在工业和生活中有广泛的应用前景,除了具有明显的节约成本的优点外,还具有操作方便、容易、维护量小等特点,可编程控制的软启动功能也减少了对设备的冲击,使设备运行的方式更趋于合理,设备的自动化水平得到了提高。随着工业生产的迅速发展,企业对机床的可靠性的要求也不断提高;再加上目前产品生产成本较高,利用先进的PLC控制技术,设计改造现有的老式机床应用成为必然的选择和趋势。
