The invention discloses a three-dimensional laser machining positioning measuring device on the basis of a multi-axis linkage numerical-control machine tool and a method implemented by the three-dimensional laser machining positioning measuring device. The three-dimensional laser machining positioning measuring device comprises a CCD (charge coupled device) detection system, a movement control system and a display system. A laser machining head is mounted at the tail end of the five-axis linkage numerical-control machine tool, the CCD detection system is mounted at the tail end of the five-axis linkage numerical-control machine tool along with the laser machining head and comprises a CCD sensor, an industrial microscope lens and an indication system, and both the CCD sensor and the indication system are mounted on the industrial microscope lens. Various movement axes of the multi-axis linkage numerical-control machine tool move, so that the spatial position and a spatial gesture of a CCD measuring device mounted on the laser machining head can be adjusted, workpiece positioning points can be accurately positioned and observed, and spatial coordinates of the corresponding positioning points in a coordinate system of the machine tool can be acquired. The three-dimensional laser machining positioning measuring device and the method have the advantages of modular measuring units, easiness in detachment and high measurement precision. Besides, large workpiece high-precision positioning measuring requirements can be met during laser machining.
Description
technical field [0001] The invention relates to the field of three-dimensional laser processing (including three-dimensional laser cutting, welding, etching, etc.), in particular to a positioning and measuring device and method for workpieces in three-dimensional laser processing, which are mainly realized based on multi-axis linkage numerical control machine tools. Background technique [0002] Laser processing technology has been widely used in modern industrial production due to its high efficiency, high precision, non-contact, strong material adaptability and high degree of process flexibility. The combined laser processing technology that installs the laser processing head on the five-axis linkage CNC machine tool expands the traditional mechanical processing machine tool into a new equipment that can complete three-dimensional complex shape laser processing. The patent application number is 201110106793.1 and the invention "a three-coordinate galvanometer scanning lase...
