基于PLC的压装试漏一体机控制系统设计与实现

Design and Implementation of PLC-based Control System for Press-Fit Leak Testing Machine

针对生产线中对于螺栓压装试漏一体机的动作要求,开发了一种螺栓压装试漏机的控制系统。设计了气压、液压回路,确定PLC的输入/输出点数并选择PLC的基本型号、扩展单元、特殊模块和触摸屏。控制系统可以实现手动和自动控制两种模式,手动控制时可以用按钮实现单步运行,自动控制时利用磁性开关和接近开关实现信号的采集和反馈。生产结果表明,该控制系统具有良好的可行性和可靠性。

In view of the operation requirements of bolt pressing assembly and leakage testing machine in production line,the control system of bolt pressing assembly and leakage testing machine is developed.The design of air pressure,hydraulic circuit,determine the PLC I/O points and select the basic model of PLC,expansion unit,special module and touch screen.The control system can realize manual control and automatic control two modes,manual control can use button to achieve single-step operation,automatic control using magnetic switch and proximity switch to achieve signal acquisition and feedback.The production results show that the control system has better feasibility and reliability.
