Laser cutting machine tool with self-adaptive air suction function

The utility model discloses a laser cutting machine tool with a self-adaptive air suction function. The laser cutting machine tool comprises a machine tool body with a transverse rail and a longitudinal rail. A cutting assembly; an air suction assembly; the cutting assembly comprises a laser head, a transverse movement component and a longitudinal movement component. The air suction assembly is provided with an air suction opening; the air suction assembly is configured to open an air suction opening in the corresponding position according to the longitudinal position of the laser head to absorb metal dust particles generated in the laser cutting process. The laser cutting device has the advantages that due to the arrangement of the cutting assembly and the air suction assembly, only the air suction opening in the cutting position works in the laser cutting process, the metal dust particle adsorption effect is guaranteed, and meanwhile the power needed for adsorbing metal dust particles is reduced. 本实用新型公开了自适
