1、 键入文字 摘摘 要要 此次毕业设计主要是针对桥梁支座孔加工机床电气控制系统设计， 由于传统的 单面钻床不能满足高效率生产要求，因此提出双面钻床电气控制系统设计。此次设 计中双面钻床采用可编程控制器（PLC）控制，其中工作台运动控制是整个设计的 核心，普通的异步电机根本无法满足定位精确的要求，因此采用步进电机实现。由 于这个设计需求精度较高，所以所有限位开关均采用接近开关。另外不同批次加工 时需要调整限位开关位置，因此设计中还提出点动控制方案，方便调试。 本文通过对双面钻床的结构和运动介绍， 选用步进电机与驱动器结合控制工作 台运动和 PLC 全程控制的方案。设计了步进电机与驱动器连接电路、触

2、摸屏面板控 制和电气控制系统原理图，根据双面钻床运动分析和要求，设计出运动流程图、电 气控制硬件系统及选型、 软件程序， 最终再通过力控组态软件对双面钻床进行仿真、 调试。 此次双面钻床设计主要是在传统加工上进一步改进， 以实现高效率、 高精度、 自动化生产需求。 【关键词】桥梁支座、双面钻床、可编程控制器 AbstractAbstract 键入文字 This graduation design is mainly directed against the bridge bearing hole processing machine tool design, the traditional s
