【摘要】 文章通过对双面二工位铣钻组合机床主要结构和运动形式的探究,以及对机床的工作过程和控制要求分析,给出了机床动作循环图,并采用三菱FX2n-64MR型PLC作为机床控制系统的核心,阐述了系统的硬件结构和工作原理,列出了输入/输出的地址分配表,绘制了PLC的外部接线图和机床主电路图,设计了软件控制程序,并采用分支程序的方法,使机床可工作在手动、自动两种模式。整个系统进行了调试并投入运行一段时间后表明,故障率低,可靠性高,提高了设备的生产效率。更多还原

【Abstract】 In this paper,the main structure and motion form of two-station and two-dimensional shining and drilling modular machine tool are discussed and the w ork process and control requirement are analyzed,the movement cycle diagram of machine tool given.The types of Mitsubishi FX2n-64MR PLC are regarded as the core of control system of machine tool.The hardw are structure and principle of operation are explained,the input and output address tables are listed and the outer w iring diagram of PLC is draw n.And the control softw are is programmed in this system.The machine tool can be operated by manual and automatic models though the w ay of branching program.The failure rate of the machine tool is reduced and reliability is raised,therefore the productivity is promoted after the system is put into operation,after the performing adjustment and period of time running.更多还原
