  • Resistance welding gun with independent actuators
    Patent number: 7952046
    Abstract: An actuator assembly for a welding gun is provided that has at least three positions in the example. The actuator assembly includes separate working and retract actuators. The working actuator includes a working rod movable between first and second positions. The retract actuator includes a retract rod independently movable relative to the working rod between third and fourth positions. The retract actuator is external to and non-concentrically arranged relative to the working actuator in the example shown. Actuation of the working and retract actuators is coordinated to provide at least three positions while enabling the actuators to be changed or modified independently from one another. A latching device is configured to selectively interlock the working and retract actuators to one another automatically in response to movement the working rod from the first position to the second position.
