镗孔机床电气(PLC)控制系统毕业设计.doc

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（1.5KW，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  ABSTRACT In recent years, the PLC abnormal rapid technological development, the manufacturer has introduced a number of powerful new PLC, various special function modules and communication networking devices, set to become the PLC computer technology, automation technology, ICT integration in the general industrial control devices, industrial automation become a powerful tool in the various fields of industrial control has been widely used. The boring lathe is one kind of precision sizing engine bed, mainly uses in processing on the work piece the precision column hole. These holes axis core often requests strictly horizontal or vertical, the distance request is very accurate. These requests are the drilling machine achieve with difficulty. The aggregate machine-tool is uses for to process the massive identical work pieces specially the special-purpose processing equipment, the special-purpose boring lathe drives by the three-phase asynchronous machine, electrical machinery model Y100L-6 (1.5KW,4A), unidirectional revolution. The technical personnel must grasp its processing technical process, to feed system use the hydraulic pressure, to enhance the work efficiency to feed to have enters quickly enters two kinds with the labor to fluctuate for the time being trades, controls the transformation by the hydraulic pressure electrical machinery and solenoid valve YV1-YV4. The hydraulic pump electrical machinery is Y801-2 (750W,1.9A). This time designs the model which the PLC hardware u
