Description

Technical Field

[0001] The utility model relates to the technical field of focusing devices, and more specifically, to a focusing device for laser cutting equipment. Background Art

[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, causing the workpiece to reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a slit is eventually formed in the material, thereby achieving the purpose of cutting. The laser cutting process replaces the traditional mechanical knife with an invisible beam. It has the characteristics of high precision, fast cutting, no limitation on cutting pattern, automatic typesetting to save materials, smooth incision, and low processing cost. In order to enable the laser cutting machine to have the function of focusing, a focusing device is generally installed at a suitable position.

[0003] However, most of the existing focusing devices achieve focusing by loosening the cutting head and moving the position of the cutting head. Although this focusing method can achieve the focusing function, it is very easy for the cutting head to move out of the focusing device during focusing, resulting in low practicality and convenience of the focusing device when used.
