A device about gantry robot system of keystone plate arc welding

摘要

The present invention relates to a gantry robots for arc welding of rail vehicles keystone plate; The object is improved by having a compression means for urging the full width direction of the weld member and welding means for welding the welding member to the gantry robot productivity and product quality of the weld by the full depression of the welding member, AUTO to provide a gantry robot for arc welding the keystone plate of a railway vehicle capable of stabilizing the welding quality by the function. ; the invention for achieving the above object is haejugo connecting the vertical members 11 and the vertical member 11 to be moved along a rail 13 installed in both sides of the welding member welding means 20 In the gantry robot consisting of girders 12, which is installed, the connection block 26 to the top of the girder (12) so as to project forwardly of the gantry robot 10 is provided, perpendicular to the connection block 26 and the welding torch installed at the ends 23 of the plurality of arc welding, the welding spots that member to a articulated robot 21 provided with the welding means 20 and the girder of the gantry robot (10) (12) vertically height-adjustable number of compression device 31 is provided, the compression device 31 is provided to be connected in the horizontal direction with a compression unit 35 that compresses the welding member in the width direction compression means 30, is provided on the gantry robot 10, the articulated robot 21 and the welding torch 23 is moved to the welding position by the coordinates, characterized in that configured in the robot controlling section 22 for controlling to welding Gantry robots for arc welding of rail vehicles keystone plate.
