A riveting device for assembly and riveting of reverse push door of aero-engine

Abstract

The invention provides a reverse push door assembly riveting device for aircraft engine, which comprises a fixture, positioning components, an inner snap gauge, an outer snap gauge and a support base component. The positioning components are fixed on the erect frame of the fixture and are used to connect and position to stationary members on the two sides frames of a reverting push door to be assembled. The inner snap gauge and the outer snap gauge are used to cover and clamp the inner and outer board panels to the door frame surfaces of the reverting push door to be assembled. The support base component is fixed on the base of the fixture and is used to support the lower frame of the reverting push door to be assembled. The positioning components are four and symmetrically disposed on the erecting frames on the two sides of the fixture. The distance of two stationary members at the same side of the erecting frame of the fixture is the same as the designed distance of the two up-and-down stationary members at one side frames of the reverting push door to be assembled. The distance of two stationary members at the same side of the erecting frame of the fixture is the same as the designed distance of the two up-and-down stationary members at one side frames of the reverting push door to be assembled. Each positioning component is respectively matched with each corresponding stationary members of the reverting push door.

Description

technical field [0001] The invention belongs to the field of aero-engine assembly, in particular to a riveting device for assembly and riveting of an aero-engine reverse push door. Background technique [0002] The anti-push door is an important part of the propulsion device of the aero-engine. Its structure is complex, and it needs to be assembled and riveted smoothly with the help of corresponding technological equipment. The existing process equipment only has the function of clamping and fixing. Although it can prevent the parts from shaking during processing, the positioning reference of the existing process equipment does not coincide with the assembly reference of the parts, which affects the assembly of the parts and eventually leads to The quality of parts fluctuates greatly, making it difficult to achieve uniform quality standards. In addition, the use of existing technology and equipment to assemble and rivet the reverse push door of the aeroengine still has the ...

Problems solved by technology

The existing process equipment only has the function of clamping and fixing. Although it can prevent the parts from shaking during processing, the positioning reference of the existing process equipment does not coincide with the assembly reference of the parts, which affects the assembly of the parts and eventually leads to The quality of parts fluctuates greatly, making it difficult to achieve uniform quality standards

Moreover, using the existing technology and equipment to assemble and rivet the reverse push door of the aeroengine still has the disadvantages of low processing efficiency and high labor intensity of the operators.
