焊接摆动器PLC控制系统设计

Design of the PLC control system in welding oscillator

本系统采用PLC控制步进电机来驱动焊接摆动器,利用PLC输出脉冲频率精确,便于控制方向,使摆动器机械部分得到简化,同时步进电机步长准确、制动可靠,使得利用本系统控制的焊接摆动器,不论是摆动速度、摆动幅度还是各点驻留时间控制方便。系统稳定性完全可以满足焊接工程的需要。

The system uses the PLC controlling step motor to propel the welding oscillator.It adopts the PLC to output pulses,which frequency is precise,so it is convenient to control the direction,and the mechanic part of the oscillator is simplified.At the same time ,because of the step motors precise step and its dependable driving,the welding oscillator controlled by this system is convenient to control,not only the oscillation velocity but also the standstill time at each point .The systems stability can meet the practical need of the welding perfectly.
