Large thin-walled component complex curved surface mirroring processing method

Abstract

The invention relates to a large thin-walled component complex curved surface mirroring processing method, and belongs to the technical field of large thin-walled component processing, and especiallyrelates to a large thin-walled component complex curved surface mirroring processing method. An employed processing device is laid in a bilaterally symmetrical structure, the specially-produced processing device is employed to carry out measuring and mirroring processing, a line laser sensor is employed to measure a workpiece, a current vortex sensor is employed to measure displacement with respect to the workpiece surface, and a piezoelectric transducer is employed to measure the value of a support force. Noise removal, data compaction, data splicing are carried out on measured data, and a target curved surface is generated. Processing path planning and support path planning are carried out, a local normal vector and a dynamic support force are measured, and mirroring milling is carried out. According to the invention, after once clamping installation, measuring and mirroring processing can be carried out on the thin-walled component, and the large thin-walled component complex curvedsurface mirroring processing method is good in measuring real-time performance, high in accuracy and convenient to use. Accurate milling of thin-walled components can be achieved, the processing precision is high, and the surface quality is high after processing.

Description

technical field [0001] The invention belongs to the technical field of processing large thin-walled parts, and in particular relates to a mirror image processing method and equipment for complex curved surfaces of large thin-walled parts. Background technique [0002] Large thin-walled parts, such as aircraft skins, rocket fuel storage tanks, etc., are key parts of major equipment such as aviation and aerospace. Such parts often need to process grid structures with different quantities and shapes on one side of the workpiece, so as to reduce the mass of the parts to the greatest extent on the premise of ensuring the structural strength. Due to the large size, low rigidity and irregular shape of such parts, the processing quality has been difficult to guarantee, and the processing efficiency is also very low. At present, the manufacturing methods of the grid structure of such parts mainly include chemical milling methods and mechanical milling methods. The chemical milling ...
