《M2110A内圆磨床(实地机床)电气设备改造》

摘要

可编程控制器PLC是计算机家族中的一员,是为了工业控制应用而设计制造的,是工厂自动化的强有力工具。它把计算机的编程灵活、功能齐全、应用面广等优点与继电器系统的控制简单、使用方便、抗干扰能力强、价格便宜等优点结合起来。它不仅实现单机的控制,同时能实现多机的控制。随着PLC技术的不断发展,在自动化技术的领域中PLC起到了不可忽略的作用。由于PLC的功能优于继电器,从而逐步代替继电器实现逻辑控制,这样无论在操作、维修和保养等方面使用更加方便。

本文就根据PLC的优点对M2110A内圆磨床(实地机床)电气设备改造,将原来继电器控制电路部分进行改造,用PLC来代替继电器,实现同样的控制。使得改造后机床不仅从线路上有了优化,而且在控制,保养维修各方面多更加的简单方便,其工作的稳定性高,故障低,从而大大的改善解决了M2110A内圆磨床原有的缺点和不足。


ABSTRACT
Computer PLC programmable controller is a member of the family, is for industrial control application and the design and manufacture is powerful, factory automation tools. It had puter programming flexible, functional and wide application advantages and relay system control is simple, easy-to-use, strong anti-jamming capability, cheap bined. It not only realize the single control, and can achieve more machine control, with PLC technology unceasing development, in automation technology in the fields of PLC has played an oversight role, because the function of PLC is superior to relay, thus gradually replace relays realize logic control. So no matter in operation, repair and maintenance etc, use more convenient.
This paper, based on PLC strengths in M2110A inside grinder (field machine) electrical equipment renovation, the original relay control circuit of reforming, use PLC to replace relays, realize the same control, make not only after reforming machine from the wiring is optimized, and in control, maintenance all aspects of how much more simple and convenient operation, the work high stability, low trouble, thus greatly improve solved M2110A inside grinder original ings and the insufficiency.
