Embodiment 1

[0079] The surface profile measurement system and method of the weakly rigid thin-walled composite material component of the present invention are used to measure the profile of the heat-insulating tile with a special-shaped curved surface, and the heat-insulating tile is fixed on the mold unit, such as Figure 8 As shown, the punch 8 is used to correct and measure the inner surface of the heat insulating tile, and the specific steps are as follows:

[0080] step 1:

[0081] The special-shaped curved surface heat insulation tile is a weakly rigid thin-walled composite material component. The heat insulation tile has a curved surface structure, and the surface contour deviation is required to be within the range of -0.2mm to +0.2mm.

[0082] According to the thermal insulation tile model diagram, such as Figure 7 As shown, a set of inspection molds is processed, including the punch 8 and the die 1. In this embodiment, the punch 8 is used to correct and measure the inner surfa...

Abstract

The invention relates to a system and method for measuring the surface profile of a weakly rigid thin-walled composite material component, belonging to the technical field of profile measurement, and solves the technical problems that the existing weakly rigid thin-walled composite material component is easily deformed and the profile is difficult to measure. The surface profile measurement system of the weakly rigid thin-walled composite material member of the present invention includes a mold unit, a fixing unit, a sealing unit and a vacuum unit; the mold unit is used to fix and correct the member to be measured; the fixing unit is arranged between the mold unit and the unit to be measured The conforming contour of the component is used to fix the component to be tested; the sealing unit is used to seal the component to be tested and seal the component to be tested in the sealed space; the vacuum unit is used to vacuum the sealed space where the component to be tested is located to correct The component to be tested, and then the profile of the component to be tested is measured. The surface profile measurement system and method of the weakly rigid thin-walled composite material component of the present invention can correct the profile of the component to be measured, and then accurately measure the profile of the profile.

Description

technical field [0001] The invention relates to the technical field of profile measurement, in particular to a profile measurement system and method for weakly rigid thin-walled composite material components. Background technique [0002] In order to meet the heat protection requirements of high-speed aircraft, its outer surface generally needs to be pasted with thermal protection materials that adapt to the shape of the aircraft. Due to the higher requirements on the aerodynamic shape of the outer surface of the aircraft, higher requirements are placed on the profile of the thermal protection material. In order to meet the requirements of the aerodynamic shape of the aircraft, the thermal protection material on the outer surface of the aircraft is generally made of composite materials, and generally consists of a large number of segmented composite materials through bonding and splicing. The outer surface of the composite materials needs to be measured before splicing. Onl...
