1、基于PLC的立式车床控制系统设计 基于 PLC 的立式车床控制系统设计 摘 要 在国民经济的各条战线上广泛使用着大量的车床、机器、仪器及工具等，这些 工艺装备都是由机械制造工业提供的。 2003 年 4 月 19 日从第七届中国国际机床展获悉，随着科学技术不断发展， 机床的发展也越来越快，机床也正朝着高性能、高精度、高速度、高柔性化和模 块化方向发展。 高性能：随着数控系统集成度的增强，机床也实现多台集中控制，甚至远距离 遥控。高精度：机床本身的精度和加工件的精度越来越高，而精度的保持性要好。 高速度：机床各轴运行的速度将大大加快。高柔性：机床的柔性化将向自动化程 度更高的方向发展，将管理、物
2、流及各相应辅机集成柔性制造系统。模块化：机 床要缩短周期和降低成本，就必然向模块化方向发展，这既有利于制造商又有利 于客户。 我国近几年机床虽然发展较快，但与国际先进水平还存在一定的差距，主要表 现在：可靠性差，外观质量差，产品开发周期长，应变能力差。为了缩小与世界 先进水平的差距，有关专家建议机床企业应在以下六个方面着力研究：1、加大 力度实施质量工程，提高机床的无故障率。 2 、跟踪国际水平，使机床向高效 高精方面发展。 3 、加大成套设计开发能力上求突破。 4 、发挥服务优势，扩 大市场占有率。 5 、多品种制造，满足不同层次的用户。 6 、模块化设计，缩 短开发周期，快速响应市场。 机
3、床使用范围越来越大，国内国际市场容量也越来越大，但竞争也会加剧，我 们只有紧跟先进技术进步的大方向，并不断创新，才能赶超世界先进水平。 本文中所作的工作如下： （1） 介绍了车床、立式车床、可编程控制器的基本概念 （2） 阐述了的系统结构以及其工作原理 （3） 设计了整个控制系统 关 键 字： 立式车床 P L C 2 基于 PLC 的立式车床控制系统设计 Abstract On each front in national economy extensive use a flood of lather, machine, instrument and tool etc.s, these cr
