Laser cutting machine

Abstract

The invention discloses a laser cutting machine. The laser cutting machine comprises a base, a box with an opening formed in the top, a clamp, a workpiece feed mechanism, a workpiece discharge mechanism, a cutting head used for cutting workpieces, a first lifting mechanism, a supporting frame arranged on the upper surface of the base and located over the box and smoke pumping pipes used for pumping smoke dust in the box. The first lifting mechanism is in sliding connection with the supporting frame, a first sliding rail is arranged on the upper surface of the base, and the box is in sliding connection with the first sliding rail. The clamp is fixed in the box. The first lifting mechanism is in sliding connection with the supporting frame and is close to the rear end of the first sliding rail. The cutting head is fixedly connected with a lifting shaft of the first lifting mechanism. Butt-joint holes in butt joint with the smoke pumping pipes penetrate through the rear side wall of the box, and the smoke pumping pipes are parallel to the first sliding rail. The laser cutting machine has the advantages that cutting efficiency is high; the smoke pumping pipes adsorb the smoke dust in acentralized manner, and the smoke dust is prevented from being emitted to workshops; and the position between a supporting table and a fixed arm can be adjusted, and therefore the workpieces with different radii can be cut.

Description

technical field [0001] The invention relates to the technical field of laser cutting, in particular to a laser cutting machine. Background technique [0002] The cutting head of the laser cutting machine cuts the workpiece. In order to improve work efficiency, the laser cutting machine works continuously. Sparks, smoke and waste are generated during the cutting process. These sparks and waste will fall into the material box, while the smoke and dust If the sparks and waste are not cleaned up in time, it will affect the cutting accuracy and cutting efficiency. If the dust is not absorbed in time, it will have a great impact on the working environment of the workshop; at the same time, when the outer diameter of the workpiece changes, the existing It is difficult for the laser cutting machine to cut around the workpiece. In order to prevent the cutting head from cutting the fixture, different fixtures need to be replaced, and the versatility of the fixture is not strong. Con...
