Embodiment Construction

[0025] The invention provides a focusing device and a focusing method for a laser cutting system.

[0026] Please see figure 1 , figure 1 Shown is a schematic structural view of the laser cutting focusing device of the present invention. The laser cutting system focusing device 100 of the present invention includes a measuring table 1 , a measuring ruler 3 and a cutting test piece 2 .

[0027] The measuring platform 1 is a triangular platform of a right-angled triangle with a longitudinal section, and the triangular platform includes two mutually perpendicular first rectangular planes ACDD' and second rectangular plane A'C'DD', both of which are perpendicular to the first rectangular plane. The first triangular surface CC'D and the second triangular surface AA'D' of the plane ACDD' and the second rectangular plane A'C'DD', and the first rectangular plane ACD D', the second rectangular plane A' C'D D', the slope AA'C'C where the first triangular face CC'D and the second tria...

Abstract

The invention provides a device and a method for focusing a laser cutting system. The device for focusing the laser cutting system comprises a measuring table which is provided with an inclined test plane and a measuring scale which is vertical to a cutting plane, wherein the test plane of the measuring table is used for bearing a cutting test piece and ensuring that the cutting test piece intersects with the cutting plane so as to detect the position of a focal plane of cutting laser; and the measuring scale is used for measuring the vertical distance between the focal plane and the cutting plane. The device has the advantages of simple structure and low cost, is convenient to operate and is intuitive. The invention also provides a focusing method using the device for focusing the laser cutting system.

Description

technical field [0001] The invention relates to a focusing device of a laser cutting system, and at the same time, the invention also relates to a focusing method using the focusing device of a laser cutting system. Background technique [0002] Laser cutting is the use of high-power-density laser beams to scan the surface of the material, heating the material to thousands to tens of thousands of degrees Celsius in a very short period of time to melt or gasify the material, and then use high-pressure gas to melt or vaporize the material from the cutting seam Blow away to achieve the purpose of cutting materials. Laser cutting, because the traditional mechanical knife is replaced by a laser knife, the mechanical part of the laser knife head has no contact with the workbench, and it will not scratch the work surface during work; the laser cutting speed is fast, the incision is smooth and flat, and generally no subsequent processing is required ;Small cutting heat-affected zon...
