基于PLC的钻孔组合机床控制系统设计

针对传统钻孔组合机床用继电器-接触器来对液压系统进行控制时出现的控制性能不好且控制系统设计和调试困难等问题,采用可编程控制器（PLC）控制方式来替代继电器-接触器控制组合机床中的动力滑台液压系统,并使用了触摸屏技术.开展了对动力滑台液压系统工作流程的分析,选择三菱PLC型号,进行了PLC硬件和软件控制系统的设计,在计算机上利用三菱编程软件GX-Developer进行了编程,以及利用仿真软件GX-Simulator进行了模拟调试,以保证满足机床使用要求.研究结果表明,该种控制系统及其设计方式既提高了钻孔组合机床控制系统的可靠性、维护的方便性等工作性能,同时也提高了设计效率.

Design of drill hole modular machine tool control system based on PLC

The traditional machine tool is driven by hydraulic pressure system and controlled by relays and contactors,so the control performance is not good and the scheme is designed and tested difficulty.Aiming at these problems,PLC and touch screen were used instead of relays and contactors to control the hydraulic system in the modular machine tool.The work flow of power sliding feed was an alyzed and the type of PLC was selected.The hardware and software of control system were designed basing on the work flow.It was programmed with the software Gx-Developer and the control program was tested with the software Gx-Simulator to ensure which could satisfy the use requirement.The results indicate that the control performance and the design efficiency are proved.
