【摘要】 为了实现火工品闭气塞的自动检测,利用可编程控制器(PLC)进行整体控制设计.以顺序控制继电器指令(SCR指令)作为实现控制的主要设计方法,实现了闭气塞的输送、定位、检测、抓取等环节按一定时序有节拍的控制.对闭气塞的几何尺寸、表面缺陷和表面粗糙度各参数的检测可以一次性顺序完成,并可实现零件的连续自动检测.在上位机中使用工控组态软件编写监控程序以实现检测系统的运行控制.实践结果表明:该方法与传统检测法相比较,显著的提高了闭气塞检测精度,检测速率每分钟可达12~16件,且性能稳定,控制品质好.更多还原

【Abstract】 Programmable Logic Controller(PLC) is used to control the detection for gas lock valve.The instruction of Sequence Control Relay(SCR) is used as the primary design method to achieve feeding,locating testing and fixing gas lock valve intermitently and in sequence.The control system can complete the examination of the geometric sizes,the surface defect and the surface roughness once a time,and can realize continuous and automatic examination.In the PC the industrial control configuration software is used to develop monitoring program of the detecting system.The practice proves that the method can improve the detecting precision of the gas lock valve remarkably comparing with traditional methods,and the speed of detecting can reach up to 12～16 piece/min.The performance is stable and control quality is good.更多还原
