Laser machining head for machining a workpiece by means of a laser beam
First Claim
1. A laser machining head for machining a workpiece by means of a laser beam, comprising:
- a head housing through which the laser beam passes along a central axis;
a carrier member for a lens optics system for focusing the laser beam, said carrier member being mounted on the head housing and displaceable relative to the latter in the direction of the central axis;
a first setting device including a cable connected to the carrier member and a cable drum connected to the head housing, the cable extending from the carrier member to the cable drum only to be wound up thereon, in order to move the carrier member towards the head housing; and
a second setting device for displacing the carrier member in the direction away from the head housing, said second setting device being separate from the first setting device.

Abstract
A laser machining head for machining a workpiece by a laser beam. The head has a head housing through which the laser beam passes along a central axis. A carrier member for a lens optics system for focusing the laser beam is mounted on the head housing and is displaceable relative to the latter in the direction of the central axis. A first setting device includes a cable connected to the carrier member and a cable drum connected to the head housing for winding up the cable in order to move the carrier member towards the head housing. A second setting device causes the carrier member to be displaced in the direction away from the head housing, with the second setting device being separate from the first setting device.
