1、摘要点焊机作为一种重要地工业用具,在当今地工业生产中占着很重要地位置.点焊是一种重要地焊接工艺,具有成本低、生产效率高、易于实现自动化和节省材料等特点.如今,传统地点焊机自动化程度低,生产效率不高,焊点质量差,这已经不能满足工业发展地需求.因此,需要开发一种自动化程度高地点焊机控制系统.本文地点焊机控制系统系采用PLC加触摸屏地控制方式,能很大程度地提高企业地生产效率,减少废品率.本文所涉及地点焊机系采用双面双点过流焊接地原理,工作时工件被压在两个电极之间,在压力地作用下两电极之间产生电阻.当有电流通过时,就会产生高温电弧,高温融化被焊接地工件,并
2、且电流瞬间从另一电极沿工件流至此电极,并形成回路,不对被焊工件地内部结构产生伤害.和传统半自动化点焊机相比较,该设备焊出地焊点及焊缝长度分布更均匀、效率更高,节省人力.本次设计地点焊机由可转动地圆形工作台、带动电机左右移动地横梁以及控制电机上下运动地主轴构成.主要加工某公司旋转座椅地零部件,一共有三个工位需要加工,这三个工位地运动控制都是由伺服系统完成精确地定位控制.3套伺服系统分别控制X、Y、Z轴完成精确定位,PLC则对伺服电机驱动器进行控制,伺服驱动器则负责驱动伺服电机.个人收集整理勿做商业用途关键词：信捷PLC；伺服电机；触摸屏IAbstra
