1、专用镗孔机床PLC控制系统的设计摘要近年来,可编程控制器技术的发展异常迅猛,各生产厂家也推出了许多强大的新型PLC,各种特殊功能模块和通信联网器件,使可编程控制器成为集微机技术、自动化技术、通讯技术于一体的通用工业控制装置,成为实现工业自动化的一种强有力的工具,在工业控制的各个领域得到了广泛的应用。镗床是一种精密加工机床,主要用于加工工件上的精密圆柱孔。这些孔的轴心线往往要求严格地水平或垂直,相互间的距离要求很准确。这些要求都是钻床难以达到的。组合机床是专门用来加工大量同一工件的专用加工设备,专用镗床由三相异步电机拖动,电机型号Y100L-6型(1.
2、5KW,4A),单向运转。技术人员必须掌握其加工工艺流程,进给系统采用液压,为提高工效进给有快进和工进两种且自动变换,由液压电机和电磁阀YV1-YV4控制变换。液压泵电机为Y801-2(750W,1.9A)。本次设计PLC硬件采用的型号是FX2N-16MR-001,设计的程序采用的是以转换为中心的单序列的编程方式。最后,由于时间的仓促,本设计难免有疏忽和遗漏的地方,我真诚的希望老师给予批评和指正。关键词PLC;硬件系统;软件系统;程序设计26ABSTRACTInrecentyears,thePLCabnormalrapidtechnologicald
