A laser machining system for machining a workpiece uses a laser beam, preferably for cutting or welding a workpiece using a laser beam. The laser machining system includes a machining head with a housing having an opening for emitting the laser beam from the machining head, a measuring device configured to direct an optical measurement beam through the opening, and an optical unit for aligning the laser beam and the optical measurement beam, the optical unit being settable to adjust the laser beam and the optical measurement beam perpendicular to the optical axis of the machining head in the region of the opening. The measuring device is further configured to determine a setting of the optical unit corresponding to the central alignment of the laser beam on the basis of measurement values based on reflections of the optical measurement beam for different settings of the optical unit.

Laser machining system and method for a laser machining system

A machining head is provided for a laser machining system configured to machine a workpiece using a laser beam. The machining head includes a housing having an opening for emitting the laser beam from the machining head; at least one reflective reference at the housing; and a measuring device configured to direct an optical measurement beam towards the opening and the at least one reflective reference. The measuring device is further configured to determine a distance (d) between the end portion and the workpiece on the basis of a first reflection (A) of the optical measurement beam from the at least one reflective reference and a second reflection (B) of the optical measurement beam from the workpiece.

A laser processing head for processing a workpiece by means of laser beam, including a housing through which a beam path for the laser beam is led and which has a focusing optical unit for focusing the laser beam onto a joint of the workpiece to be processed. A light cutting device is fitted to the housing and has a light source for generating a light line on the workpiece. A camera is arranged in an observation beam path in front of the camera such that the camera images the light line at the location to be joined and also the portion. The system also includes an image processor which calculates a minimum distance between the stored target trajectory and the current welding path midpoint.

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.
