Novel welding robot

Abstract

The invention discloses a novel welding robot. The novel welding robot comprises a workbench, two stand columns arranged on the side face of the workbench and symmetrically arranged in parallel, a cross beam arranged on the side faces of the top ends of the stand columns, a transverse moving mechanism arranged on the side face of the cross beam, a cantilever beam arranged at the movable end of thetransverse moving mechanism, a robot body arranged at the bottom of the cantilever beam and spirally fixed to the cantilever beam, a welding clamp arranged at the tail end of the robot body, a welding gun clamped and fixed through the welding clamp, and a hydraulic overturning clamping table arranged below the robot body. The novel welding robot has the technical effects that the transverse moving mechanism is matched with the robot body, so that the robot body can transversely move, the welding range is widened, large-size workpieces are welded, the welding freedom degree is improved throughthe synergistic effect of the robot body and the hydraulic overturning clamping table, and all-dimensional welding is achieved.

Description

technical field [0001] The invention relates to the field of robot welding, in particular to a novel welding robot. Background technique [0002] Industrial robot is a multi-purpose, reprogrammable automatic control operation machine with three or more programmable axes, used in the field of industrial automation, in order to adapt to different purposes, and welding robot is engaged in automatic welding work Industrial robot, welding robot is to install welding tongs or welding torch on the flange of the final axis of industrial robot, so that it can carry out welding. [0003] However, most existing welding robots use a screw to fix the base, and use the extension of the robotic arm of the robot to make the welding torch close to the welding spot and perform welding, so that the welding range is only the size of the extension of the robotic arm of the robot, and the extension of the robotic arm of the robot is too large , will also increase the burden on the joint motor du...

[0003] However, most existing welding robots use a screw to fix the base, and use the extension of the robotic arm of the robot to make the welding torch close to the welding spot and perform welding, so that the welding range is only the size of the extension of the robotic arm of the robot, and the extension of the robotic arm of the robot is too large , will also increase the burden on the joint motor due to the self-weight of the mechanical arm, so that the welding accuracy will decrease under long-term work; in addition, the existing robots only have five or six axes, and the degree of freedom is low. When pointing, it is easy to cause interference and collision between the robot and the workpiece, resulting in damage to the robot
