WORKPIECE SECURING DEVICE FOR FRICTION STIR WELDING DEVICE

摘要

A workpiece securing device or a friction stir welding device is constituted of a starting-end-side workpiece stopper that positions a welding starting-end-side end of a workpiece to be placed on a workpiece surface plate; a finishing-end-side workpiece stopper that positions a welding finishing-end-side end of the workpiece; a starting-end-side workpiece clamping mechanism that presses and secures a portion along a welding line close to the welding starting-end-side end of the workpiece against the workpiece surface plate from above; and a finishing-end-side workpiece clamping mechanism that presses and secures a portion along the welding line close to the welding finishing-end-side end of the workpiece against the workpiece surface plate from above. In a state where the welding starting-end-side end and the welding finishing-end-side end of the workpiece placed on the workpiece surface plate are positioned, only the portions along the welding line close to the welding starting-end-side end and close to the welding finishing-end-side end of the workpiece are secured.

主权项

1. A workpiece securing device for a friction stir welding device comprising:
a workpiece surface plate on which each of workpieces serving as objects to be welded is to be placed in a state where the workpieces are butted against each other; a starting-end-side workpiece stopper that positions a welding starting-end-side end where friction stir welding of each workpiece is started, at an upstream end of the workpiece surface plate in a friction stir welding traveling direction; a starting-end-side workpiece clamping mechanism that presses and secures a portion along a welding line between the workpieces close to the welding starting-end-side end of each workpiece against the workpiece surface plate from above; a finishing-end-side workpiece stopper that positions a welding finishing-end-side end where the friction stir welding of each workpiece ends, on a downstream side of the workpiece surface plate in the friction stir welding traveling direction; and a finishing-end-side workpiece clamping mechanism that presses and secures a portion along the welding line between the workpieces close to the welding finishing-end-side end of each workpiece against the workpiece surface plate from above.
