Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting fixtures, in particular to a fixture for laser cutting of aluminum plates. Background Art

[0002] Laser cutting uses a high-energy-density laser beam to heat the workpiece, causing the temperature to rise rapidly and reach the boiling point of the material in a very short time, forming vapor. As the vapor is ejected, an incision is formed on the material. When laser cutting aluminum substrate materials, a clamp is generally used to fix the aluminum plate to prevent the aluminum plate from shifting before laser cutting. Existing laser cutting clamps usually require multiple pressing clamps to fix the aluminum plate. This process consumes a lot of processing time, which has a certain impact on cutting efficiency. In addition, when performing large-scale arc cutting, the laser cutting tool moves too far, which affects the cutting accuracy. Utility Model Content
