Embodiment Construction
[0061] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0062] Such as Figure 1 to Figure 3 For the blade product 1 that needs to be assembled in this embodiment, it can be seen that the blade product 1 is mainly composed of a blade body part 10 , an upper edge plate assembly 11 , a lower edge plate assembly 12 and a shaft 13 . The upper edge plate assembly 11 is installed at one end of the blade airfoil 10 , and the lower edge plate assembly 12 and the shaft 13 are installed at the other end of the blade airfoil 10 .
[0063] The upper edge plate assembly 11 is composed of upper edge plate one 110, upper edge plate two and upper edge plate three 111, upper edge plate four 112, upper edge plate five and upper edge plate six 113; the lower edge plate assembly 12 is composed of lower edge plate One and lower edge plate two 120 and lower edge plate three 121 form.
[0064] combine Figure 4 to Figu...

Aiming at the problems that ceramic-based composite material aeroengine blade products are difficult to assemble and the assembly quality is difficult to guarantee, the present invention provides a ceramic-based composite material aeroengine small blade assembly tool and an assembly method, and the assembly tool includes a blade body positioning tool and an upper edge plate Component assembly tooling and lower edge plate and shaft assembly tooling; blade body positioning tooling is used to position and fix blade body parts to ensure that when the blade body parts are fixed on the blade body positioning tooling, the outer profile of the blade body parts is completely consistent with the inner profile of the blade body positioning tooling Fitting; use the assembly tooling of the upper edge plate assembly to fix the upper edge plate assembly and realize the angular assembly and positioning of the upper edge plate assembly and blade body parts; use the lower edge plate and shaft assembly tooling for shaft positioning and compression to ensure that the shaft and the blade Body coaxiality, and realize the angular assembly and positioning of the lower edge plate assembly and blade airfoil parts. In the present invention, the blade body is used as the assembly reference of the subsequent parts to reduce the risk of faults in the processing of the fiber cloth layer. The tooling is used to ensure the coaxiality of the shaft and the blade body, taking into account the assembly realization and machinability.
Description
technical field [0001] The invention belongs to the field of parts processing and assembling of aero-engines, and in particular relates to a continuous fiber reinforced ceramic matrix composite material aero-engine small blade product assembling tool and an assembling method. Background technique [0002] Continuous fiber reinforced ceramic matrix composite (hereinafter referred to as: ceramic matrix composite) is a new type of strategic material with thermal structure / function integration that combines the advantages of metal materials, ceramic materials and carbon materials. It has high temperature resistance, low density, high Specific strength, high specific modulus, anti-oxidation, anti-ablation, insensitive to cracks, and no catastrophic damage, etc., are widely used in aviation, aerospace, satellite aerospace, nuclear energy, photovoltaics and other fields. [0003] The engine relies on blades to complete the cutting and compression of high-temperature and high-pressu...
