Assembly tool and assembly method for rudder shaft type component for ceramic-based composite aircraft

Abstract

The invention relates to a rudderpost component assembly tool, in particular to a rudderpost component assembly tool for a ceramic-based composite aircraft and an assembly method. The technical problems that an existing ceramic-based composite rudder shaft component is tedious in assembly process, poor in assembly precision and assembly quality, high in requirement for preparation of a single part and high in cost are solved. The assembly tool comprises a shaft positioning assembly and a framework assembly positioning assembly. The shaft positioning assembly comprises a bottom plate, and a V-shaped seat and a shaft pressing plate which are arranged on the bottom plate; the shaft pressing plate and the V-shaped seat are connected to form a triangular frame structure for fixing and limiting the rudder shaft; the framework assembling and positioning assembly comprises a supporting seat and a framework limiting block which are arranged on the bottom plate; a first kidney-shaped hole and a second kidney-shaped hole are formed in the supporting seat and the framework limiting block respectively, correspond to pin holes in the two sides of a connecting beam of the rudder shaft component respectively and are used for positioning the framework assembly. The invention further provides a method for assembling the rudder shaft component through the tool.

Description

technical field [0001] The invention relates to a rudder shaft component assembly tool, in particular to a rudder shaft component assembly tool and an assembly method for a ceramic-based composite aircraft, which are mainly applied to high-strength, oxidation-resistant, high-temperature-resistant composite material aircraft structure thermal protection field. Background technique [0002] Ceramic-based composite material has the advantages of metal materials, ceramic materials and carbon materials. It is a new strategic material integrating thermal structure and function. It has high temperature resistance, low density, high specific strength, high specific modulus, oxidation resistance, Ablation, insensitivity to cracks and no catastrophic damage, etc., have a wide range of applications in aviation, aerospace, satellite aerospace, nuclear energy, photovoltaics and other fields. [0003] Due to the limitation of the current composite material weaving and molding technology,...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to solve the cumbersome assembly process, low assembly accuracy, high requirements for the preparation accuracy of individual parts, high assembly cost and problems in the composite skeleton in the assembly method of the rudder and wing of the existing ceramic-based composite aircraft. Due to many deficiencies such as non-coplanar facets and rudder shaft axes, it is difficult to meet the technical problems of various performance index requirements of aircraft thermal protection products, and an assembly tooling and assembly method for rudder shaft components used in ceramic matrix composite aircraft is provided.
