Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, and in particular to a novel optical fiber positioning device for an optical fiber laser cutting machine. Background Art

[0002] Fiber laser cutting machine is a laser cutting machine that uses a fiber laser generator as a light source. Fiber laser is a new type of fiber laser newly developed internationally that outputs a high-energy-density laser beam and focuses it on the surface of the workpiece, causing the area on the workpiece irradiated by the ultra-fine focal spot to instantly melt and vaporize. Automatic cutting is achieved by driving the fiber spot irradiation position through the movement of the three-axis CNC positioning device.

[0003] In the prior art, a three-axis CNC positioning device includes an X-axis mechanism, a Y-axis mechanism arranged on the X-axis mechanism, and a Z-axis mechanism arranged on the Y-axis mechanism. The three-axis CNC positioning device drives the operation of the optical fiber cutter, but waste chips and sparks are easily splashed when the optical fiber cutter is working, which can easily damage the optical fiber cutter over time and reduce the service life of the optical fiber cutter.
