Abstract

A tool support mechanism for a robot is adapted for carrying a tool, such as a welding torch. A series of shafts, pulleys and belts cooperate such that upon rotary input, a first arm rotates about a first end thereof with respect to a frame, a second arm rotatably connected at a first end thereof to a second end of the first arm translates but does not rotate with respect to the frame, and a tool support rotatably connected to a second end of the second arm translates but does not rotate with respect to the first arm. The mechanism thus allows a tool to be rotated about an axis spaced from the axis of rotary input.
