Ring workpieces are widely used in the manufacturing industry.Aiming at the welding problem of double-sided straight welds in the processing process of circular workpieces,an automatic welding device for the double-sided straight weld of the ring based on PLC control is proposed,which mainly includes a mechanical structure module and a motion control module.The mechanical structure includes a gantry,a transverse moving mechanism,a longitudinal moving mechanism,a welding torch slewing mechanism,a workpiece rotation mechanism,a wire feeding module and a control cabinet.The motion control module includes human-machine touch screen HMI,programmable logic controller PLC,motor driver,solenoid valve and miniature photoelectric sensing.By operating the HMI touch screen of the motion control module,each mechanism of the mechanical structure module is controlled to perform the corresponding action process,so that each mechanism cooperates with each other to complete the automatic welding of the double-sided straight weld of the ring workpiece.The motion simulation results show that the device has simple structure,convenient control,and can complete the automatic welding of double-sided straight welds of the ring workpiece,which improves the welding efficiency and welding quality.
