去毛刺专用机床电气控制系统设计 摘要 本次设计的去毛刺专用机床是适用于生产进行加工过程中零件产生的毛刺去除。由于该机控制系统采用了先进的电气、液压与机械紧密结合，动作程序互锁、监控严格的程序控制系统，所以具有自动化程度高、生产能力强、操作简单可靠和维修方便等特点。主要进行了对电气控制系统的改进，在以前继电器控制系统产品的基础上，采用了工业控制专用计算机——可编程控制器控制系统。在PLC及外部电气系统控制下，通过控制进给油泵电机、主轴电机、冷却电机、等三个电磁阀的逻辑程序动作，完成去除各类零件的毛刺任务。 此次设计，是根据生产机械的控制要求，去毛刺专用机床电气控制系统的设计和完成电控装置在制造、使用和维护过程中所需的图样和资料，要求利用功能和优点较为齐全的可编程控制器（PLC）来对去毛刺电气控制系统进行控制及运行，以及机床电气控制对系统液压回路的控制来完成整个零件加工过程的动作要求，从而来完成整个操作过程中的各项任务。 关键词：主轴电机、去毛刺电气控制系统、机床电气控制、PLC Deburri
