Problems solved by technology

The changing process of different nozzles, especially new nozzles, has hitherto not been automated and is therefore usually carried out manually, since the nozzle changers used on laser processing machines usually only exchange nozzles of the standard nozzle type

Embodiment Construction

[0030] Figure 1a , 1b shows a nozzle changer 1 with a plurality of nozzle receptacles 2 in a support device 3 comprising a housing with a cover. In the exemplary embodiment shown, three of the nozzle holders 2 are equipped with nozzles 4a, 4b, 4c of different types, ie with different outer contours.

[0031] Each nozzle holder 2 comprises a stepped nozzle storage chamber 5 with a plurality of nozzle storage locations 5a, 5b, 5c which are respectively arranged on different planes perpendicular to the nozzle removal direction Z. , and are misaligned with each other in a stepwise manner. The nozzle storage chamber 5 has an opening 7 through which the different nozzles 4 a , 4 b , 4 c can be introduced into and removed from the nozzle storage chamber 5 . In the present exemplary embodiment, each nozzle storage location 5 a , 5 b , 5 c has an annular receiving contour 6 a , 6 b , 6 c which is designed to receive the respective nozzle 4 a , 4 b in a form-locking manner. , the outli...

Abstract

The holder (2) has a nozzle storage chamber widening along nozzle removal direction (Z) to a nozzle removal opening. The nozzle storage chamber comprises two nozzle storage seats that are offset in steps from each other, where the chamber stores nozzles (4a-4c). Each nozzle storage seat includes a circumferential receiving contour that holds the nozzles securely against rotation. The nozzle storage seat includes a clamping and a snap-in locking device that produces holding force along direction opposite to the removal direction. The locking device includes a slide unit. An INDEPENDENT CALIM is also included for a laser processing machine for processing work pieces.

Description

technical field [0001] The invention relates to a nozzle holder for a nozzle changer, a nozzle changer with a plurality of nozzle holders and a laser processing machine with such a nozzle changer for use in laser Mounting and / or removal of nozzles on a processing head of a processing machine. Background technique [0002] A device for mounting / removing laser nozzles with multiple nozzle holders is known from EP 2 078 584 A1. [0003] A laser nozzle mounted on a processing head of a laser processing device for processing can become soiled or damaged due to collisions with workpiece parts, spatter and dirt from the processing. The laser nozzle is therefore a wearable part which should be replaced regularly for reasons of process reliability. Nozzle changes are also required when changing the material type or material thickness of the workpiece and when implementing new machining strategies such as 2D laser cutting with mirror cutting heads and / or with water cooling, in which...
