ABSTRACT:
An apparatus is provided for clamping components during machining, in particular during welding of sheet-metal components arranged in two or multiple layers. The apparatus includes a holder for a machining head, in particular for a laser machining head, a pressure-exerting element fitted on the holder in a movable fashion relative thereto, a pressure-exerting device provided operatively between the holder and the pressure-exerting element and having a first actuating element for moving the pressure-exerting element relative to the holder into a first direction, and a second actuating element for moving the pressure-exerting element into a second direction which is opposite to the first direction, and a force-setting device for controlling the pressure-exerting device in order to set a clamping force. During welding, the clamping force is exerted on the sheet-metal components by the pressure-exerting element.
