Automatic focusing double-mirror cavity laser cutting head

Abstract

The invention provides an automatic focusing double-mirror cavity laser cutting head which comprises a base, a connector, a focusing mirror member, a capacitor head and a spray nozzle, and further comprises an anti-bumping mechanism, an automatic focus adjustment mechanism and a water cooling ring. The focusing mirror member comprises a first mirror cavity and a second mirror cavity; the first mirror cavity is internally provided with a first drawer-type mirror base; the second mirror cavity is internally provided with a second drawer-type mirror base; the first drawer-type mirror base is internally provided with a 7.5-inch focusing mirror; and the second drawer-type mirror base is internally provided with a 5-inch focusing mirror. The cutting head is provided with double mirror bases, and the 5-inch focusing mirror or the 7.5-inch focusing mirror can be installed manually. The cutting head has the automatic focusing function, and can program to adjust the position of the focus. The cutting head also has the anti-bumping function, and collision at any angle in a radial plane can be detected, so that halt is executed at once so as to protect the cutting head; after collision is eliminated, the cutting head can automatically return to the original work position to cut continuously; and a water cooling manner is adopted for a lens, thereby effectively prolonging the service life of the lens.

Description

technical field [0001] The invention relates to a laser cutting machine, in particular to an automatic focusing double-mirror cavity laser cutting head in the laser cutting machine. Background technique [0002] As a new type of thermal cutting technology, laser cutting has the advantages of fast cutting speed, high production efficiency, good cutting end surface quality, small heat-affected zone and environmental protection. It has become one of the main sheet metal cutting methods and has been widely used. Applications. With the continuous development of high-power laser technology, the processing capacity, efficiency and quality of laser cutting are constantly improving. However, the existing high-power laser cutting machines still have the following problems: 1. The structure of the cutting head is simple, the function is single, and the focusing mirror can only be installed at a fixed position; 2. Although some cutting heads have adopted anti-collision technology, they...

Problems solved by technology

However, the existing high-power laser cutting machines still have the following problems: 1. The structure of the cutting head is simple, the function is single, and the focusing mirror can only be installed at a fixed position; 2. Although some cutting heads have adopted anti-collision technology, they are all simple. 3. The air-cooled cooling method is used, the lens is not cooled uniformly, and the cooling capacity is not enough, which cannot meet the requirements of high-power laser cutting machines; 4. The lens focal length adjustment adopts manual adjustment. ,low efficiency

The above shortcomings have brought great inconvenience to the application of laser cutting and limited the application field of laser cutting
