摘要
以普通连杆颈铣床为研究对象,通过对机床主要结构和运动形式的探究以及对机床工作过程和控制要求的分析,采用P LC控制系统的设计方法,选择合适的P LC与变频器,进行系统软硬件设计,列出了PLC的I/O地址分配表,绘制了电气接线图和自动工作流程图,编写了P LC控制程序的梯形图并调试,再结合液压传动系统,完成了整个电气控制系统设计。采用P LC控制系统,使机床的性能和稳定性得到很大的提升,也便于维护和技术升级。
Taking general crankshaft milling machine as the study object,through the exploration of the machine’s main structure and movement,this paper has designed the system software and hardware by following PLC control system method and selecting suitable PLC and inverter.With the PLC I/O address allocation worksheets listed,the electric diagram and the automatic flow chart drawn,the ladder diagram of PLC programmed and debugged,it has completed the design of the whole electrical control system with the combination of the Hydraulic transmission system.The PLC control system makes the milling machine obtain better performance and stability,and offers convenience for maintenance and upgrading.
