摘　　要：静触头是大电流隔离开关的关键导电部件,静触头与接线铜板进行垂直铆合,需在底部铆合处进行表面焊接加固。针对人工碳弧焊接时存在劳动强度大、生产效率低以及高热量、强弧光作业环境恶劣等问题,提出静触头多轴步进运动自动焊接控制方案,并设计了相应的主电路、人机界面、PLC控制系统和控制软件。试验结果表明,所设计的静触头多轴自动焊接系统能完成静触头焊接、碳棒进给及弧长的控制;所采用的PID控制算法能促进燃弧稳定,提高焊接质量,使得自动焊接的静触头能满足实际生产要求。The static contact is the key conductive part of the high current disconnector.The static con⁃tact shall be riveted vertically with the wiring copper plate,and the surface is welded to reinforce at the bot⁃tom riveted part.Aiming at the problems of high labor intensity,low production efficiency and poor working environment with high heat and strong arc light in artificial carbon arc welding,the automatic welding control scheme of multi axis stepping motion of static contact is proposed,and the main circuit,man-machine inter⁃face,PLC control system and control software are designed.The experimental results show that the designed static contact multi axis automatic welding system can complete the control of static contact welding,carbon rod feeding and arc length.The PID control algorithm can promote the stability of arc burning and improve the welding quality,so that the automatically welded static contact can meet the actual production require⁃ments.
