Description

Technical Field

[0001] This utility model belongs to the technical field of gantry laser cutting equipment, specifically relating to a gantry laser automated cutting equipment. Background Technology

[0002] Gantry laser cutting equipment is an advanced piece of equipment commonly used in metal processing and other fields. It mainly includes a gantry operating frame, laser cutting head, transmission system, worktable, and control system. Gantry laser cutting equipment uses a laser generator to produce a high-energy-density laser beam, which is guided to the cutting head through a transmission system such as optical fiber or reflector. The focusing lens in the cutting head focuses the laser beam onto the surface of the material to be cut, causing the material to absorb a large amount of laser energy instantly, reaching its melting or boiling point, thereby achieving melting or vaporization.

[0003] Workpiece fixing fixtures are an important component of gantry laser cutting equipment. They are usually fixed on the worktable of the gantry laser cutting equipment to clamp and fix the workpiece, ensuring the stability of the workpiece during the cutting process and avoiding vibration, slippage or rotation that may affect the cutting accuracy.
