Three-dimensional laser head for CO2 nonmetal laser cutting

Abstract

The invention provides a three-dimensional laser head for CO2 nonmetal laser cutting. The three-dimensional laser head is characterized by comprising a C-axis rotating assembly, a B-axis swinging assembly and a laser head body, the B-axis swinging assembly is installed on a rotating shaft of the C-axis rotating assembly, and the laser head body is installed on a swinging shaft of the B-axis swinging assembly. The C-axis rotating assembly can rotate by n*360 degrees, the B-axis swinging assembly is installed on the rotating shaft of the C-axis rotating assembly and can swing by + / -135 degrees, and it is guaranteed that laser beams in the B-axis swinging assembly can be accurately reflected all the time in the movement process and are stably output through a focusing lens of the laser head body; and the processing capacity range of a three-dimensional laser cutting machine is expanded.

Description

technical field [0001] The invention belongs to the technical field of laser cutting, and belongs to a three-dimensional CO for non-metallic laser cutting. 2 laser head. Background technique [0002] In recent years, composite materials have been widely used in aviation, aerospace, shipbuilding, high-speed rail, automobile and other industrial fields due to their excellent performance; composite materials usually have the characteristics of high hardness, high strength, poor thermal conductivity, anisotropy and discreteness, etc. As the structural complexity and processing precision of components are getting higher and higher, traditional processing methods are becoming more and more difficult to meet the processing requirements of composite material components; 3D CO 2 Laser cutting machine can realize efficient and high-precision processing of complex structural components of composite materials, and is an inevitable choice to meet the processing requirements of such comp...
