Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a clamping device for laser cutting plates. 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, low processing cost, etc. It will gradually improve or replace traditional metal cutting process equipment.

[0003] Publication No. CN214109272U discloses a plate clamping device for a laser cutting machine tool, which drives the left and right fixed blocks to move toward each other by energizing the electric push rod. When the fixed block contacts the plate on the surface of the machine tool body, the electric push rod drives the moving block to move, and the moving block drives the guide groove to move. During this process, the guide column moves upward on the left and right sides of the guide groove. When the guide column moves, it drives the pressure plate to rotate with the fixed axis as the center of the circle, so that the pressure plate contacts the top of the plate. The device uses a series of mechanical structures to enable the fixed block to fit closely with the left and right side walls of the plate after moving, and the moving block drives the pressure plate to fit closely with the plate after moving, so that the plate is tightly fixed on the surface of the machine tool body, which is very convenient to use.
