Abstract

The invention relates to a shape-correcting device special for an aerial irregularly shaped extruding structure component. The shape-correcting device is composed of two parts, i.e., a hardware system and a software system, wherein the hardware system mainly comprises a roller system, a main driving system, a screw rod feeding system and a frame; the software system is divided into two parts; one part takes a displacement sensor as a main part for controlling the feeding precision; the other part takes a force sensor as a main part for optimizing the correcting according to a correcting experience. Compared with the prior art, the shape-correcting device has the advantages that the bending-torsion compound correcting is adopted, and the correcting precision is high; the digital correcting is adopted, so that the efficiency is high; parts in different sizes are corrected, and the flexibility is high.

Description

technical field [0001] The invention relates to a digitally adjustable special orthopedic device for testing different sizes of aerospace special-shaped extruded structures. Background technique [0002] The use of structural parts occupies a very important position in the design of aviation products, and is the most important part of the aircraft's aerodynamic shape and body skeleton. The material of aerospace structural parts is mostly made of aluminum alloy. Due to the complex shape and poor welding performance in the actual processing process, in order to ensure the accuracy, extrusion molding is often used for processing and production. Due to the influence of various factors, the workpiece often has shape defects during extrusion, cooling and transportation. Some profiles will have arc bending or section deformation such as flange inward, outward expansion and torsion. In order to control the accuracy of the workpiece, it is necessary to correct the workpiece to obta...
