Robot welding arm

Abstract

The robot welding arm comprises a bottom plate, a rotating disc is movably arranged at the upper end of the bottom plate through a rotating shaft, a first mechanical arm is movably arranged at the upper end of the rotating disc through a rotating shaft, and a second mechanical arm is movably arranged at the upper end of the first mechanical arm through a rotating shaft; a laser welding head is movably arranged at the end, away from the first mechanical arm, of the second mechanical arm, a wire stacking mechanism is arranged on the outer side surface of the first mechanical arm and comprises a fixed frame, a telescopic rod, a wire guide wheel, a spring and a rubber hose, and the fixed frame is fixedly arranged in the middle of the outer side surface of the first mechanical arm. And a plurality of telescopic rods are uniformly and fixedly arranged on the side wall of the inner side of the fixed frame. The device is good in using effect, when the second mechanical arm and the first mechanical arm rotate relative to each other, a control cable and a power supply cable connected with the laser welding head can be stored or released according to needs, and therefore the using effect of the device can be improved.

Description

technical field [0001] The invention relates to the technical field of robot welding, in particular to a robot welding arm. Background technique [0002] Welding robots are industrial robots engaged in welding (including cutting and spraying). According to the definition of the International Organization for Standardization Industrial Robot Terminology Standard Welding Robot, an industrial robot is a multipurpose, reprogrammable, automatic control manipulator with three or more programmable axes, used in the field of industrial automation. In order to adapt to different purposes, the mechanical interface of the last axis of the robot is usually a connecting flange, which can be connected to different tools or end effectors. The welding robot is equipped with a welding tongs or a welding (cutting) torch on the flange of the final axis of the industrial robot, so that it can perform welding, cutting or thermal spraying. [0003] However, in order to facilitate the rotation a...

Problems solved by technology

[0003] However, in order to facilitate the rotation and extension of the mechanical arm, the current welding robot often needs to install a long connecting cable to facilitate the rotation and extension of the mechanical arm. It is unsightly that the cables are exposed on the outside of the device, and it is also easy to cause long cables to be entangled with other components and affect the use
