Abstract

The invention relates to the field of railway vehicle welding, and discloses a double-machine cooperation automatic welding method for a railway vehicle side beam inner rib. The side beam inner rib iscomposed of lower cover plates, rib plates, vertical plate assemblies and spring barrels, structural simulation of the side beam inner rib is completed through a welding sample plate, and specific forms of sample plate welding seams are determined according to welding angles and welding seam positions; backing welding of long welding seams between the vertical plate assemblies and the lower coverplates, backing welding of welding seams between the rib plates and the lower cover plates, backing welding of welding seams between the rib plates and the vertical plate assemblies, backing weldingof annular welding seams between the spring barrels, backing welding of ultra-deep welding seams between the spring barrels and the vertical plate assemblies, sealing face welding of long welding seams between the vertical plate assemblies and the lower cover plates, and sealing face welding of ultra-deep welding seams between the spring barrels and the vertical plate assemblies are conducted in sequence; welding parameters of backing welding, filling welding and sealing face welding are determined; and the welding quality is controlled, specifically, the assembling gaps, the pretreatment quality and the three-point-crossed welding seam quality are controlled. The invention further discloses a system. Through the method and the system, the welding efficiency of the side beam inner rib canbe improved, and welding deformation is effectively controlled.

Description

technical field [0001] The invention relates to the technical field of rail vehicle automatic welding, in particular to a dual-machine cooperative automatic welding method for rail vehicle side beam inner ribs. Background technique [0002] Automatic welding has been used normally in the welding of inner ribs of side beams of rail vehicles. The existing single-machine welding of inner ribs of side beams usually takes 2 hours / group, and each robot can meet the production capacity of 2 vehicles per day (two shifts). Due to the increase in production volume and the limitation of the plant area, it is required to increase the utilization rate of the unit plant area under the condition that the original plant area remains unchanged, so as to achieve a production capacity of 3 vehicles per day. This requires improving the efficiency without increasing the floor area of ​​the robot. Now Some manipulators use double-wire welding to improve welding efficiency. Double-wire welding has...
