Abstract
A multiple arm weld includes at least two weld gun arms where one arm retracts away from mating work pieces while at least one other arm remains operational, thus allowing a multiple arm weld gun to act as a single arm weld gun. Once one or more weld gun arms is retracted, the remaining weld gun arms may be repositioned with respect to the work pieces in a space not previously accessible to the multiple arm weld gun before retraction of an arm.
Claims15
A weld gun comprising:
- at least two weld gun arms capable of simultaneous welding operation;
- and
- an actuator attached to at least one of said weld gun arms for moving said weld gun arms between an engaged and a disengaged position, said actuator further capable of moving said at least one of said weld gun arms to a retracted position without interfering with operation of the remaining weld gun arms.
A weld gun comprising:
- at least two weld gun arms, each arm including opposed electrodes for creating welds on a work pieces;
- at least one of said weld gun arms further including:
- first and second jaws, said first jaw rotationally connected to said second jaw at a first connection point,
- said first jaw further connected to an actuator, whereby movement of said actuator along a fixed, preset path imparts rotational movement of said first jaw with respect to said second jaw about said first connection point, and
- said actuator further capable of moving said first jaw rotationally about said first connection point away from said second jaw to a first jaw retracted position.
