基于PLC的钢筋笼焊点动态定位控制系统

Dynamic Positioning Control System for Pile Cages Welding Spot Based on PLC

为了提高钢筋笼焊点焊接过程中焊枪稳定性,进而提升焊点焊接质量,设计了一种基于PLC的钢筋笼焊点动态定位控制系统。根据钢筋笼动态焊点运动规律,制定了焊点动态定位原理,设计了钢筋笼焊点动态定位系统气动原理图,描述了焊点动态定位系统工作过程,在此基础上对PLC控制系统的硬件和软件进行了设计。该系统有自动控制和手动控制两种模式,自动控制模式下可实现对动态焊点的捕捉、跟随焊接、回原点等循环运动控制,焊接动作稳定;可根据钢筋笼形状、桩径大小,对焊点动态定位系统作出适当调整,灵活性好、适应性强。

In order to improve the welding torch stability and then improve the welding spot quality,a dynamic positioning control system for pile cages welding spot based on PLC is designed.According to the dynamic welding spot movement rule,the principle of the welding spot dynamic positioning is developed,and the pneumatic principle diagram of the system is designed.Based on the system working process,the hardware and software of the PLC control system is designed.The system is divided into two modes:automatic control mode and manual control mode.Being in the automatic control mode,the system can achieve the cycle motion control of dynamic welding spot capture action,follow welding and return action,hence the welding movement is stable.According to the shape and size of pile cages,the system can make appropriate adjustment.As a result,it is more flexible and suitable.
