Problems solved by technology

The disadvantage of this arrangement is that, due to the introduction of the drive torque, and the arrangement of the flexible support extending into the lever arm, a low level of torsional rigidity is provided, so that the drive movement to the adjustment movement of the optical element is precise and direct delivery is impossible
In fact, angular errors can occur in the eccentric due to the torque support in the flexible support

Embodiment Construction

[0030] FIG. 1 shows a perspective view of a processing head 11 of a laser processing machine, which is not shown in detail. 2 shows a schematic sectional view of a processing head 11 with a beam guide 12 arranged thereon having at least one optical element 15 by which a laser beam 13 is deflected and focused by a focusing lens 16 . A laser beam 13 is emitted through a cutting gas nozzle 17 to produce a cut in a workpiece 18 . A distance measuring device 19 is arranged between the workpiece 18 and the cutting gas nozzle 17 , which generates a potential difference between the metallic nozzle body of the cutting gas nozzle 17 and the also metallic workpiece 18 . Arranged on the processing head 11 is a positioning device 21 which includes at least one movement drive 41 and which may have a measuring device 23 for controlling and monitoring the movement drive 41 . A coolant supply 25 is provided in the upper region of the processing head 11 in order to cool the at least one optica...

Abstract

The invention relates to a transmission element (52) for transmitting a raw movement generated by a movement drive (41) to an optical element as an adjustment movement, said transmission element comprising at least one solid joint (65, 66), wherein the The transfer element (52) has a first solid joint (65) which is mechanically rigid in a first direction of motion (53) tangential to the path of motion of the positioning motion and which is mechanically rigid in the other direction perpendicular to the first direction of motion. has a low level of stiffness in the direction of motion and wherein said transmission element (52) has a second solid joint (66) which is mechanically rigid in the first direction of motion (53) of the first solid joint (65) , and is elastic in a direction perpendicular to the first direction of motion (53) and the second direction of motion.

Description

technical field [0001] The invention relates to a transfer element for transferring a generated output motion from a motion drive to an optical element during a positioning movement, a positioning device, and a processing head for a laser processing machine with such a transfer element. Background technique [0002] From DE 10 2008 030 783 B1 a method is known for the angled cutting of workpieces with a laser beam, as well as a laser processing machine for implementing the method, in which the ultrasonic cutting gas flow from the cutting gas nozzle is supplied in an oblique The cutting angle is directed towards the workpiece surface. There, the workpiece and the laser cutting beam are moved relative to each other, wherein the inclined cutting angle is at right angles to the feed direction. During this relative movement, the position of the laser cutting beam on the workpiece surface is adjusted in such a way that the laser cutting beam impinges on the workpiece surface in t...
