The structure design of the mobile welding robot based on rotating arc sensor forthe bend welding-seam weld

摘要

This article introduce a machine of the mobile welding robot based on rotating arc sensor for the bendrnwelding-seam weld. The robot is driven by two middle wheels, and we placed two universal wheels in the frontrnand the rear of wheel robot to balance the robot body. It not only enhance the quickness of the robot, but alsorndecrease the difficulty of control. The cross-slider is controlled by two DC servo motor. We use the rotating arcrnsensor that make welding torch and sensor combination. The structure of sensor is compact and it is real-time. Thernconnection block of welding torch and cross-slider is the conbination structure. We use the connection block withrnrotational joint when the angle of welding seam is the frequent or big change. The robot's structure is compact andrnagile that realize the automation welding about the planar bend welding-seam and the planar fillet welding-seam.
