Abstract: A friction welding system includes a first spindle and a second spindle. The first spindle and the second spindle securely locate a first part and a second part, respectively. The first spindle defines a first axis. The second spindle defines a second axis. A tailstock fixture is disposed along the first and second axes to securely locate a third part. A motor rotates the first and second spindles. A controller controls the motor and the angular orientation of the first and second spindles. The first spindle is moveable along the first axis. The second spindle is movable along the second axis. The first part and the second part can contact the third pat while rotating to effect two separate fiction welds. The controller controls the rotational position of the first spindle and the second spindle upon completion of the weld.

Abstract: A device for receiving and processing an elongated workpiece that proceeds along a path is disclosed. The device comprises a plurality of clevis-shaped members, each clevis-shaped member being pivotable about a vertical axis and having a pair of spaced apart upwardly extending posts. The clevis-shaped members are spaced apart relative to the path, and the posts of each clevis-shaped member defining therebetween a centered workstation disposed along the path. At least one actuator is provided, with the actuator operatively engaging each of the clevis-shaped members such that the each clevis-shaped member will pivot about its vertical axis. Accordingly, in response to operation of the actuators the posts of each of the clevis-shaped members shift in unison to center and clamp the workpiece at the workstation.
