Problems solved by technology

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power-density laser beam through the optical path system; the laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point, and at the same time the high-pressure gas coaxial with the beam will melt or The vaporized metal is blown away; as the relative position of the beam and the workpiece moves, the material finally forms a slit, so as to achieve the purpose of cutting; the existing laser cutting machine, because its laser cutting head can only move horizontally during the cutting process Therefore, the focal length of the laser is fixed, so workpieces with uniform thickness must be used. This operation makes laser cutting have certain limitations, and it cannot be freely cut for workpieces with uneven thickness; the existing laser cutting machine is in For workpieces of different thicknesses, users need to adjust the cutting power of the laser cutting machine in advance to ensure that the cut workpieces can be cut thoroughly and at the same time save energy to the greatest extent. Therefore, before replacing workpieces with different thicknesses All adjustments must be made, such an operation is not conducive to improving the efficiency of laser cutting; in summary, there are defects

Abstract

The invention provides an automatic focusing high-efficiency laser cutting device. The automatic focusing high-efficiency laser cutting device comprises a sliding module, a connecting rod, a detection module and an adjusting module. The sliding module comprises a sliding block and a tension spring. The sliding module is provided with a sliding shell. The sliding shell is internally provided with a cavity. A sliding groove is formed in the portion, making contact with a laser cutting head, of the sliding shell. The lower end of the sliding shell is provided with a through hole. The detection module is designed into a circular ring shape. The adjusting module comprises an adjustment lever. An adjustment groove corresponding to the sliding groove is formed in the portion, making contact with the laser cutting head, of the adjusting module. The automatic focusing high-efficiency laser cutting device can automatically change the position of a laser cutting focus according to the thickness of a workpiece and meanwhile adjust the laser cutting strength for more flexible cutting.
