Apparatus, a fastening device, method and system for clamping a piece as well as a fastening clamp

An apparatus for clamping a piece, said apparatus including

• a frame portion adapted to be fastened to a base,
• a fastening clamp disposed in the frame, having first and second jaw components on the opposite sides and a wedge member fitted therebetween,
• a fixing stopper, the piece being adapted to be clamped between the fixing stopper and the first jaw component of the fastening clamp,
• an arrangement disposed between the second jaw component of the fastening clamp and the fixing stopper, functionally connecting said second jaw component of the fastening clamp and the fixing stopper to each other, for moving the fixing stopper by means of the fastening clamp which arrangement includes a slide, moveably fitted to the frame portion, in which the fixing stopper is disposed and on which the fastening clamp is adapted to act.

A fastening device for clamping a piece, said fastening device including

• a frame portion adapted to be fastened to a base,
• at least one fastening position disposed in the frame portion for a fastening clamp, having first and second jaw components on the opposite sides and a wedge member fitted therebetween,
• a fixing stopper, the piece being adapted to be clamped between the fixing stopper and the first jaw component of the fastening clamp,
• an arrangement disposable between the second jaw component of the fastening clamp and the fixing stopper, functionally connecting said second jaw component of the fastening clamp and the fixing stopper to each other, for moving the fixing stopper by means of the fastening clamp which arrangement includes a slide, moveably fitted to the frame portion, in which the fixing stopper is disposed and on which the fastening clamp is adapted to act.

A method for damping a piece, wherein

• a piece is placed between the fixing stoppers included in a fastening device,
• the distance between the fixing stoppers is reduced for damping the piece between them,
• and wherein a fastening clamp is used having first and second jaw components on the opposite sides and a wedge member disposed therebetween, and
• one of the fixing stoppers is formed with the first jaw component of the fastening clamp,
• the second jaw component of the fastening clamp is arranged to act on the other fixing stopper to move it,
• the position of the second fixing stopper is varied with the second jaw component of the fastening clamp.

A system for clamping a piece to a machine tool, said system including

• a base, equipped with fixing stoppers, disposable in a machine tool,
• at least one fastening device including
• a frame portion adapted to be fastened to a base,
• a fastening clamp disposed in the frame portion, having first and second jaw components on the opposite sides and a wedge member fitted therebetween,
• a fixing stopper of the fastening device, the piece being adapted to be clamped between the fixing stopper and the first jaw component of the fastening clamp,
• an arrangement disposed between the second jaw component of the fastening clamp and the fixing stopper of the fastening device, functionally connecting said second jaw component of the fastening clamp and the fixing stopper of the fastening device to each other, fix moving the fixing stopper of the fastening device by means of the fastening clamp which arrangement includes a slide, moveably fitted to the frame portion, in which the fixing stopper is disposed and on which the fastening clamp is adapted to act.
