Abstract

The invention belongs to the field of mechanical tools, and particularly relates to a clamp for assembling aero-engine fan-shaped block assemblies. According to the technical scheme, the clamp for assembling the aero-engine fan-shaped block assemblies comprises a chassis rotating unit, a positioning pressing unit, a cantilever welding unit and an angular scale plate, wherein the positioning pressing unit, the cantilever welding unit and an angular scale unit are mounted on the chassis rotating unit, the positioning pressing unit is used for pressing and positioning inner runner plate and outerrunner plates of the fan-shaped block assemblies, the cantilever welding unit is used for welding blades of the fan-shaped block assemblies to the inner runner plates and the outer runner plates, andthe angular scale plate is used for angular positioning of the cantilever welding unit. According to the clamp for assembling the aero-engine fan-shaped block assemblies, the assembling size precision and the consistency of positioning welding points can be ensured.

Description

technical field [0001] The invention belongs to the field of mechanical tooling, and in particular relates to a fixture used for assembling aeroengine sector block components. Background technique [0002] The aero-engine sector block assembly is an important part of the compressor, as attached Figure 4 As shown, the fan-shaped block assembly is made by welding the inner runner plate, blade and outer runner plate. It is necessary to ensure that the relative positional relationship of each part meets the requirements of the design drawings. The axial and radial relative relationship between the inner and outer runners needs to be controlled during assembly Position size, the prior art cannot meet the process requirements. Contents of the invention [0003] The invention provides a fixture used for assembling an aeroengine sector block assembly, which can ensure the dimensional accuracy of assembly and the consistency of positioning welding points. [0004] Technical schem...
