Patent ID: 7952052

Claim:
A maintenance center for cleaning a welding torch nozzle comprising: a chassis; a reaming assembly mounted on the chassis including: a lifting mechanism advancing and retracting a reaming head; a driving motor rotating the reaming head for reaming a nozzle about a rotation axis; a clamp assembly for holding and centering the nozzle, the clamp assembly comprising: a slider and a pair of jaws pivotally coupled to the slider, the slider movable in a direction substantially transverse to the rotation axis, wherein the movement of the slider toward and away from the rotation axis moves the pair of jaws substantially transverse to the rotation axis and the slider movement; a pair of pins movably coupled with the slider, for opening and closing the jaws in conjunction with the movement of the slider; and an actuating mechanism for opening and closing the clamp assembly, the actuating mechanism being coupled to the slider; an electric input; and an electronic operation controller controlling the reaming assembly, the controller having a single-input teaching mode and a reaming mode, wherein during the single-input teaching mode, the controller permits manual sequencing of each step of the reaming mode without activating the driving motor by operating the electric input, and at each step, storing the position of the lifting mechanism, the clamp assembly and the actuating mechanism to be used during the reaming mode.
