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 weak-rigidity thin-wall composite component profile outline measuring system and method, and belongs to the technical field of profile measurement. The technical problems that an existing weak-rigidity thin-wall composite component is prone to deformation, and the profile outline is hard to measure are solved. The weak-rigidity thin-wall composite component profile outline measuring system comprises a die unit, a fixing unit, a seal unit and a vacuum pumping unit. The die unit is used for fixing and correcting a to-be-detected component. The fixing unit is arranged on the outline, attached to the to-be-detected component, of the die unit and used for fixing the to-be-detected component. The seal unit is used for sealing the to-be-detected component and sealing the to-be-detected component in the sealed space. The vacuum pumping unit is used for conducting vacuum pumping on the sealed space where the to-be-detected component is located so that the to-be-detected component can be corrected, and profile measurement is conducted on the to-be-detected component. By means of the weak-rigidity thin-wall composite component profile outline measuring system and method, the profile of the to-be-detected component can be corrected, and accordingly the profile outline can be accurately measured.

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...
