Background

The laser cutting machine irradiates the surface of a workpiece with a high-power laser beam formed by focusing laser emitted from a laser through a light path system, so that the workpiece reaches a melting point or a boiling point, and the workpiece gradually forms a cutting seam, thereby achieving the purpose of cutting. The laser cutting processing utilizes invisible light beams to replace the traditional mechanical knife, and has the advantages of high precision, quick cutting, no limitation on cutting patterns, automatic typesetting, material saving, smooth cut, low processing cost and the like.

With the popularization of laser equipment in the field of cutting processing, the requirements on the speed and the cutting precision of a laser cutting machine are higher and higher. And factors influencing the cutting precision are diversified, such as the running precision of a cross beam, the cantilever length of a cutting head, the stability of a lathe bed and the like. The existing gantry laser cutting machine is divided into a left part and a right part for the convenience of welding, but the mode is not favorable for adjusting the parallelism and the planeness of two X axes, so that the adjusting difficulty is increased, and the overall working efficiency of the laser cutting machine can be influenced due to the fact that the machine body is not integral and the anti-interference capability is weak. Meanwhile, the guide rail of the X axis is mostly placed on the upper side of the bed body of the base by the existing gantry laser cutting machine tool, the structure can lead the distance from the cutting head to the supporting position of the guide rail of the beam to be far, the length of a cantilever of the cutting head is long, and the cutting head is easy to shake in the cutting process, so that the cutting quality is reduced.

In the current foreign five-axis laser cutting machine, a machine tool with a cantilever structure can adopt a single-side X-axis guide rail, namely, one side of a cross beam is connected to the X-axis guide rail. Although the structure can reduce the invalid length of the cantilever of the cutting head on the Z axis and simultaneously reduce the weight of the Z axis, the cantilever structure using the unilateral X axis guide rail requires that both the lathe bed and the beam part have high rigidity, and the design and the manufacture are difficult.
