Automatic welding tool for straight splicing slits of base plates of dump trucks

Abstract

The invention discloses an automatic welding tool for straight splicing slits of base plates of dump trucks, which comprises a material-placing operation platform and an automatic welder gun, wherein the automatic welder gun is arranged on the material-placing operation platform, and the automatic welder gun is electrically connected with a welding power supply; and the automatic welding tool also comprises a PLC (programmable logic controller) and a traveling mechanism, wherein the traveling mechanism controls the automatic welder gun to transversely and longitudinally move along the material-placing operation platform, and the PLC is electrically connected with the traveling mechanism. The servo drive traveling mechanism is controlled through the PLC so as to realize the automatic stable traveling of the automatic welding tool. The automatic welding of straight splicing slits of base plates of dump trucks is realized, the manual welding is replaced, and the welding quality and the welding efficiency are improved. The parameters such as welding speed, welding length and the like can be changed through changing a PLC program so as to meet the automatic welding requirements of carbon steel plates with different thicknesses; and through replacing the types and models of welders or the types and models of welding wires, the welding of straight splicing slits of base plates of dump trucks made of different materials can be realized.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a dump truck bottom plate splicing straight seam automatic welding tool for realizing the automatic welding of the dump truck bottom plate splicing and straight seam. Background technique [0002] At present, the bottom plate welding of dump trucks is performed on a simple platform. Since the length of the straight seam of the bottom plate reaches 7m, or even more than 8m, the labor intensity of the welding personnel is high. During the long-term welding process, the welding quality will be reduced and the welding efficiency will be low. Contents of the invention [0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a method that can solve the problems of high welding labor intensity, low welding quality and low welding efficiency in the above-mentioned bottom plate splicing straight seam welding p...
