Abstract
A mechanical device is used to change a laser nozzle on a nozzle receiving member of a laser processing machine for processing workpieces. The mechanical device has a nozzle magazine having a nozzle holder carrier, and at least one nozzle holder for a laser nozzle being provided on the nozzle holder carrier. The mechanical device also includes a positioning drive and a change drive, both drives having a common drive motor. Between the drive motor on the one hand and the nozzle holder carrier and the nozzle holder on the other hand, there is provided a coupling that can be switched by means of a switching device between a supply state, in which a drive connection exists between the drive motor and the nozzle holder carrier, and a change state, in which a drive connection exists between the drive motor and the nozzle holder.
