Embodiment Construction

[0014] Referring to the accompanying drawings, the embodiment shows a welding method and welding fixture for an aircraft flap slide rail structure. Aircraft slide rails are mainly composed of cross-section "I"-shaped slideways, solid and hollow webs, connecting shafts and reinforcing ribs, etc., and their materials are ultra-high-strength steels that are difficult to process. The slide rail body of the flap slide rail 1 such as figure 1 As shown, there are six adjacent abdominal cavities 2, the first abdominal cavity 2-1, the second abdominal cavity 2-2, the third abdominal cavity 2-3, the fourth abdominal cavity 2-4, the fifth abdominal cavity 2-5 and the fifth abdominal cavity Six abdominal cavities 2-6, the process requires that thin webs 13 that match the shape of the abdominal cavity need to be welded on both sides of each abdominal cavity.

[0015] In order to control the deformation during welding and improve the processing efficiency, this application specially design...

Abstract

Disclosed is a welding jig for conducting vacuum electron beam welding on an airplane flap sliding rail structural part. The structural part comprises a sliding rail body with multiple cavities and multiple webs corresponding to the cavities and needing to be welded. A body of the jig is of a flat-board-shaped rigid structure and is provided with multiple locating connecting holes, locating blocks and multiple windows, wherein the locating connecting holes and the locating blocks correspond to the appearance of the sliding rail body and the windows correspond to the cavities of the sliding rail body. The boundary of each window is larger than that of the corresponding cavity of the sliding rail body. The middle portions of the two ends of the body are each provided with a shaft-shaped connecting head. Two stand bars are located at the two ends of the body. Lug grooves are arranged at the top ends of the stand bars. The connecting heads are supported in the lug grooves in the top ends of the stand bars at the two ends respectively and fixed through plug pins.

Description

technical field [0001] The application relates to the field of electron beam welding in aviation manufacturing, in particular to a vacuum electron beam welding method and welding fixture for aircraft flap slide rail structural parts. Background technique [0002] Aircraft flap slide rail structural parts are used for the relative movement of the main flap inside and outside the aircraft to increase or reduce the lift of the wing. The material of the slide rail is ultra-high strength steel. In order to reduce the weight of the component itself and increase the rigidity of the structure , Hollow out the middle part of the slide rail body to form a plurality of abdominal cavities, and then embed web plates on both sides of the abdominal cavity for welding. [0003] Due to the strong rigidity of the structural parts, the complex shape, and the need to weld thin webs on both sides of multiple adjacent cavities, there are many welding parts and long continuous welds, which makes w...
