Laser cutting machine laser head protection device capable of automatically focusing

Abstract

The invention discloses a laser cutting machine laser head protection device capable of automatically focusing, and belongs to the field of laser cutting. The device comprises a laser head, a laser range finder, a hydraulic lifting device, an annular induction device, an inner shell, an embedded annular pressure sensor, a balance spring, a protective outer shell, an annular laser scanner, a vertical lifting device, a fixed straight rod and a horizontal displacement device; the laser head is matched with the inner shell; and the bottom of the laser head is combined with the hydraulic lifting device; the embedded annular pressure sensor is arranged in the inner shell; the balance spring is arranged on the outer circumference of the inner shell; and the annular laser scanner is arranged at the bottom of the outer shell. By adopting the laser cutting machine laser head protection device, the laser head is protected; automatic focusing can be achieved according to a set distance; inaccuracy of manual focusing is avoided; the problem of cutting failure caused by substandard material quality can be avoided; it can be guaranteed that the laser head is prevented from being collided by the outside; and meanwhile the cutting precision and efficiency are improved.

Description

technical field [0001] The invention belongs to the field of laser cutting, and relates to a laser head protection device, in particular to an automatic focusing laser head protection device for a laser cutting machine. Background technique [0002] Laser cutting machine is a kind of mechanical equipment that uses laser beam heating to cut materials at high speed. Compared with traditional cutting machines, laser cutting machines can cut a variety of materials, such as wood, plastic, rubber, carbon steel, etc., laser The application range of cutting machines is more and more extensive. [0003] Laser cutting machines are favored by users because of their high processing precision and fast speed. However, the development of laser cutting machines is limited due to the difficulty of focusing the laser head and the high maintenance cost after the laser head is often damaged due to impact. The existing focusing technology generally adjusts the adjusting bolt manually according ...

AI Technical Summary

Problems solved by technology

The existing anti-collision measures for the laser head are to avoid hitting the laser head by a large margin when changing the cutting workpiece. This measure is mixed with more human factors, and the controllability is poor, and it cannot prevent the laser head from being hit by the cutting workpiece.
