Robot automatic gouging welding steel ring workstation

Abstract

The invention provides a robot automatic gouging welding steel ring workstation. The workstation comprises a control cabinet, a base with a lifting device which is separately grounded, a roller framewhich is separately grounded for placing a steel ring, a robot in insulation connection with the lifting device, a welding torch in insulation connection with the lifting device, a gouging gun in insulation connection with the lifting device, a robot electrical circuit electrically connected with the robot, the lifting device and the control cabinet to control the robot, a welding torch electricalcircuit electrically connected with the welding torch and the control cabinet to control the welding torch, a gouging gun electrical circuit electrically connected to the gouging gun and the controlcabinet to control the gouging gun and a grounded carbon brush arranged on the roller frame and respectively connected with the gouging gun electrical circuit and the welding torch electrical circuit,so that the gouging gun electrical circuit and the welding torch electrical circuit are individually grounded through the grounded carbon brush. The workstation can prevent high-frequency plasma gouging from burning the robot and a main board of a welder.

Description

technical field [0001] The invention relates to the field of fully automatic steel ring gouging and welding, in particular to a robot automatic gouging and welding steel ring workstation. Background technique [0002] At present, the outer diameter of the workpiece steel ring is Φ504-Φ1854mm, the wall thickness is 8-96mm, the width is 200-600mm, and the weight is 64-1185.6Kg. The forming process is: steel plate flame cutting blanking, beveling-rolling machine to make a circle-shaping machine for roundness calibration. According to the technical requirements of the steel ring, the butt joint after rolling is V-shaped groove or X-shaped groove. In order to ensure the welding strength, it is necessary to weld the inner groove of the steel ring. After the inner groove is filled with welding wire, turn the steel ring 180°, and use a gouging gun to gouging the outer weld seam. Then weld and fill. Considering that the workpiece is rolled and formed by a roller plate rolling mach...

Problems solved by technology

At this time, we insulated the main functional equipment and replaced the robot main board for the second time. After using the workstation for about 2 weeks, the robot teach pendant went black and the robot main board burned out for the third time.
