Abstract

An intelligent splicing and assembling method for aspherical complex curved surface workpieces, comprising the following steps: (1) firstly designing an aspheric splicing and clamping mechanism with adjustable multi-degrees of freedom; (2) combining it with a high-performance computer and a Zygo interferometer Build an intelligent closed-loop stitching system together, and use one of the sub-mirrors as a reference to obtain the surface point cloud data of other sub-mirrors. Then, based on the aspheric surface type fast point cloud registration method, after matching with the standard surface type , the matching parameter obtained is the assembly error of the sub-mirror, and the pose of the workpiece is adjusted based on the error, that is, the intelligent splicing assembly of the aspheric workpiece is completed; the invention reduces the assembly error and reduces the surface error of the final product , It can also greatly simplify the assembly steps of this type of product, reduce the assembly adjustment time, can effectively solve the practical problems faced in the current high-precision assembly of complex curved surfaces, and meet the development needs of modern and future optical industries.

Description

technical field [0001] The invention relates to the technical field of splicing and assembling complex curved surface workpieces, in particular to an intelligent splicing and assembling method for aspherical complex curved surface workpieces. Background technique [0002] With the development of science and technology, optical systems are more and more widely used in aerospace, weapons, ultraviolet lithography, laser nuclear fusion and long-distance observation. Spherical components and aspheric components have more design freedom, which has the advantages of reducing system mass, simplifying system structure, and expanding system functions. At the same time, it can also improve resolution, correct aberrations and increase the working distance of the system. [0003] For an aspheric mirror, its caliber and surface precision will directly determine the imaging capability and imaging quality of the optical system. At present, the maximum diameter of the aspheric mirror produc...
