CUTTING BEAM MACHINE WITH A WORKING HEAD AND ARRANGED THEREON, A COUPLING FOR A NOZZLE

The device for automatically exchanging cutting nozzles (S) for cutting heads of a laser cutting machine (L), comprises a cutting head (2) comprising replaceable cutting nozzles connected with the cutting head and a nozzle changing magazine (1) arranged relative to the cutting head. The cutting head is displaceable in an X-Y plane defined by an X and a Y-direction before the nozzle change by a movement unit. The nozzle changing magazine comprises a circular magazine wheel (4, 5, 6, 7, 8) provided with holding bores for the reception of the cutting nozzles.

The nozzle changing magazine comprises a circular magazine wheel (4, 5, 6, 7, 8) provided with holding bores for the reception of the cutting nozzles. The cutting nozzles are arranged in the nozzle changing magazine, which: allows a direct withdrawal and disposal of the cutting nozzle away from the cutting head in a first magazine position and a direct entrance of the cutting nozzle into the cutting head in a second magazine position; and is rotatably arranged around a direction running parallel to the X-Y plane. The cutting head is constantly maintained in the X-Y position during the nozzle change phase and is adjustable for direct withdrawal and/or entrance of the cutting nozzle in a Z-direction running vertically to the X-Y plane. The disposal of the cutting nozzle takes place over a disposal element intended at the nozzle changing magazine. The disposal element is formed as through-bore. The cutting nozzles are arranged in a circumferential direction at the magazine wheel. The magazine wheels are arranged next to each other and form a magazine depot. The cutting nozzles are secured with a fuse element, e.g. an O-ring, with respect to falling out of the holding bores. The magazine wheel is arranged on a swiveling drive and/or support shaft, on which the magazine wheel is fastened by a clamp and/or a lock connection. The drive and/or support shaft and the magazine wheel comprise plug-on milling areas, where the plug-on milling area at the drive and/or support shaft correspond with another milling a
