Abstract:
1. A mechanical device for changing a laser nozzle of a nozzle mount of a laser processing machine for processing workpieces, the mechanical device comprising: a nozzle magazine having a nozzle holder support, a nozzle holder configured to receive the laser nozzle, which nozzle holder is supported on the nozzle holder support of the nozzle magazine, a support positioning drive configured to move the nozzle holder support and the nozzle holder in a support positioning direction, and a lifting device configured to move the nozzle holder, when the nozzle holder is positioned in a lifting stand-by position along the support positioning direction, relative to the nozzle holder support to a mount/dismount position along a positioning lifting direction extending perpendicular to the support positioning direction, wherein the nozzle holder, when positioned in the mount/dismount position, is drivable about a nozzle holder rotation axis that passes through a center of the nozzle holder, by a rotary drive such that the laser nozzle, when received by the nozzle holder, is mountable to the nozzle mount of the laser processing machine or such that the laser nozzle, when mounted to the nozzle mount of the laser processing machine, is dismountable from the nozzle mount of the laser processing machine.
