<p><P>PROBLEM TO BE SOLVED: To provide a welding robot that improves the durability of a combined one-line type power cable and that reduces the twisting of a welding wire. <P>SOLUTION: The welding robot is equipped with: an upper arm, a body rotating around a fourth axis, an oscillator oscillating around a fifth axis, a rotary body rotating around a sixth axis, a welding torch attached to the rotary body, a wire feeder installed at the base end part of the upper arm to deliver a welding wire, a conductive power feeding member where an inserting hole for a welding wire is formed in the center axis and which is provided between the upper arm and the wire feeder, and the combined one line type power cable which is connected to the tip end of the power feeding member and passes through the insertion hole of the upper arm and the body and which extends in the longitudinal direction of the body and integrates the welding wire, the electric power and gas as a unit to be supplied to the welding torch. The base end part of the power feeding member is freely rotatably attached to the welding wire delivery port of the wire feeder. The power feeding cable and the gas hose are wound around the outer circumference of the power feeding member and connected. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
