Abstract
This utility model belongs to technical field of aircraft structure design, relates to the edge sealing structure of a kind of lead-covering aluminum honeycomb sandwich construction part.Described edge sealing structure includes eyelid covering (1), lower eyelid covering (2), edge sealing member (4) and connector (6), edge sealing member (4) is Z-shaped, edge sealing member (4) is positioned at one end of honeycomb sandwich construction, the top of zigzag edge sealing member (4) is gluedd joint with upper eyelid covering (2), middle part is close on the end face of honeycomb sandwich construction side, and bottom is linked together by connector (6) with lower eyelid covering (2).Use Z-shaped edge sealing member, bonding pad can be formed in structural edge, and then can be by types of attachment such as glueing joint, rivet or be spirally connected, type of attachment simple and reliable as making lead-covering aluminum honeycomb sandwich construction part have with common metal part, reduce assembly difficulty, cut down production cost.
Description
Technical field
This utility model belongs to technical field of aircraft structure design, relates to a kind of lead-covering aluminum honeycomb
The edge sealing structure of sandwich structure piece.
Background technology
Conventional lead-covering aluminum honeycomb sandwich construction is with filler edge sealing or panel bending edge sealing, aluminum
Must pre-buried insert auxiliary connect when eyelid covering aluminum honeycomb sandwich construction part is connected with other parts
Connecing, cause type of attachment complexity single, assembly difficulty is big, and cost is high.
Summary of the invention
This utility model solves the technical problem that: provides a kind of structure, overcomes primary aluminum eyelid covering aluminum honeybee
The technical problem that nest sandwich type of attachment complexity is single, assembly difficulty is big, cost is high.
The technical solution of the utility model: described edge sealing structure includes eyelid covering 1, lower eyelid covering
2, edge sealing member 4 and connector 6, edge sealing member 4 is Z-shaped, and edge sealing member 4 is positioned at honeycomb folder
One end of Rotating fields, the top of zigzag edge sealing member 4 glueds joint with upper eyelid covering 2, and middle part is close to
On the end face of honeycomb sandwich construction side, bottom is connected to one with lower eyelid covering 2 by connector 6
Rise.
As a kind of improvement of the technical program, with honeycomb 3 in the middle part of zigzag edge sealing member 4
Between be filled with glued membrane.
As a kind of improvement of the technical program, zigzag edge sealing member 4 is made for aluminum alloy materials.
The beneficial effects of the utility model: use Z-shaped edge sealing member, can be formed even in structural edge
Meet district, and then lead-covering aluminum honeycomb can be made by types of attachment such as glueing joint, rivet or be spirally connected
The type of attachment that sandwich structure piece is simple and reliable as having with common metal part, reduces assembling
Difficulty, cuts down production cost.
Accompanying drawing explanation
Fig. 1 is lead-covering aluminum honeycomb sandwich construction of the present utility model；
In figure: 1 is upper eyelid covering, 2 is lower eyelid covering, and 3 is honeycomb, and 4 is edge sealing member, and 5 for even
Meeting district, 6 is connector.
Detailed description of the invention
Below in conjunction with the accompanying drawings the technical program is elaborated.
For making lead-covering aluminum honeycomb sandwich construction part be connected simple and reliable with other parts, it is simple to
Assembling, edge sealing form is improved by this utility model, a newly-increased Z-type edge sealing member 4；Envelope
Edge pieces 4 one end rides on eyelid covering 1, glueds joint with upper eyelid covering 1；The other end rides over lower eyelid covering 2
On, form bonding pad 5；It is filled with glued membrane in the middle part of Z-shaped edge sealing member 4 and between honeycomb 3,
Whole sandwich structure piece can simple and reliable being connected with other parts by bonding pad.Edge sealing member
4 materials are aluminium alloy；Radius bend R of edge sealing member 4 should meet 2 σ≤R≤5 σ, and σ is
The thickness of slab of edge sealing member 4 i.e. material supplied materials thickness；The bending angle of edge sealing member 4 can be according to lead-covering
The version of aluminum honeycomb sandwich construction part needs to adjust；The top fold limit following table of edge sealing member 4
Face should be parallel with the upper and lower surface of honeycomb 3 respectively with bottom fold limit upper surface；Edge sealing member 4
Top fold limit in opposite direction with bottom fold Edge Bend；The top fold limit of edge sealing member 4,
Bottom fold limit, the length on limit, middle part can need to adjust according to version；Also may be used in bonding pad 5
Formed by one end overlap joint of upper eyelid covering 1 with edge sealing member 4；The type of attachment of bonding pad 5 can basis
Version needs to select splicing, rivet or be spirally connected.
