Technical Field

The utility model relates to application of a water-guided laser technology, in particular to a water-guided laser cutting machine.

Background

The existing laser micro-jet system adopts a traditional double-swing-head five-axis machine head device processing platform, a machine head module of laser micro-jet is configured on a machine head device, wherein a workpiece carrying platform is fixed, the machine head device can do 5-axis motion, besides the machine head device can do rapid relative motion relative to a X, Y, Z axis of a workpiece coordinate system, the machine head device also comprises rotation of a C-axis (parallel to a Z axis) swing arm, swinging of a B-axis (parallel to a Y axis) swing head and normal direction (A axis and parallel to the Z axis) follow-up of the machine head device. For a laser micro-jet machine head device, the position of the machine head device needs to be continuously moved, and when the machine head device moves, particularly swings or rotates, the water jet position and the shape of the machine head module are also changed (besides the single A-axis follow-up of the machine head device, the path of a micro-water column beam is curved), and at the moment, the micro-water column beam can appear as discontinuous series of water drops, so that a laser beam coupled in the micro-water column beam is unstable, and the processing quality of a workpiece is finally influenced. Therefore, the inventor designs a novel water-guided laser processing scheme, and the design key point is that a five-axis machine head is changed into a combined structure of a one-axis machine head and a four-axis workpiece carrier, so that the curve of a micro water column beam path can be avoided, and the stability of the micro water column beam is ensured. Because of the change of the movement modes of the machine head and the workpiece, the machine table of the traditional double-swinging-head five-axis machine head device machining platform can not meet the installation requirements of the machine head device and the workpiece carrying table device in the novel water-guided laser cutting scheme.
