Description

A kind of aircraft articulamentum compaction tool

Technical field

The utility model relates to the tools that articulamentum when a kind of riveting for aircraft compresses, and are applied to aircraft assembling manufacturing In equipment Technology field.

Background technique

Riveting is type of attachment most commonly seen in aircraft assembling process.Due to connecting the difference of the number of plies, it may appear that two layers Connection, three layers of connection ... are when carrying out the riveting work of multilayer connection, due to the foozle of External Shape, the fitting of part Difference is spent, will lead to and generate certain gap between the part to fit.To eliminate this gap width (by taking countersunk rivet as an example), After rivet is put into part connecting hole, manufactured head is riveted and (controls dynamics) using riveting gun, manufactured head is completely squeezed into In nest；Then worker's nut bigger than normal than connection rivet diameter used using internal diameter, is linked in rivet nail rod, is matched with dinking It closes wooden mallet to strike nut, the gap between part is eliminated；Then riveting operation is carried out using the riveting gun of installation riveting card. Existing operating method has the following deficiencies:

1, can operating position it is limited (the small position in not applicable operating space)

For skin-surface region, the region of shelves abundance is opened, above method can realize expected purpose: eliminating connection interlayer Gap.But the articulamentum at the articulamentum of interior of aircraft structure, aircraft exterior structure acute angle is when being riveted, since access is asked Topic, be not available more than method operated.

2, easy damaged piece surface

Eliminating nut used in gap is metal material, will lead to nut when using dinking and makes to piece surface At certain damage, to influence the surface quality of product.

3, part deformation is easily led to

When being struck with wooden mallet to dinking, it is difficult to ensure that the stability of impulse force, will lead to nut unbalance stress, And nut is metal material, therefore easily lead to part and deformed because of unbalance stress (or excessive).

4, inconvenient for operation

When carrying out elimination gap operating, used tool is more: nut, dinking, wooden mallet；Nut needs basis Rivet diameter selects different size to be operated with feature contacts face size；Dismounting of nut and dinking etc. all makes with top Method it is cumbersome.

Utility model content

The purpose of this utility model be solve problems of the prior art, provide a kind of structure it is simple, it is light, can grasp The stronger aircraft articulamentum compaction tool of the property made.

To achieve the goals above, the utility model adopts the following technical solution: a kind of aircraft articulamentum compaction tool, institute The material for stating compaction tool is elastic material, including head and tail portion, and head is provided with the hole for holding rivet bar insertion along its axial direction, Tail portion and riveting gun cooperate.

Preferably, tail shape is consistent with riveting card shape.

Preferably, the end size on head is successively decreased along its axial direction to the direction far from tail portion.

Preferably, head and tail portion are on same axis.

Preferably, head is in bending, with tail portion on same axis.

Preferably, compaction tool is integrally formed.

Preferably, compaction tool material is elastoplastic.

The utility model compared with prior art, has the advantages that

1, disappearing to the gap of all sites multilayer connection connection interlayer is realized by manufacturing the compaction tool of different size It removes.

2, operation is more convenient, and can guarantee well the surface quality of part, and then shorten the production cycle.

3, the efficiency for improving multilayer connection riveting work, simplifies operation, facilitates worker's operation.

4, structure is simple, light, operability is stronger.

Detailed description of the invention

Fig. 1 is 1 structural schematic diagram of the utility model embodiment；

Fig. 2 is 2 structural schematic diagram of the utility model embodiment；

In figure, 1, head；2, tail portion.

Specific embodiment

It should be noted that identical structure uses unified digital representation in embodiment 1, embodiment 2.

The utility model is further described with reference to the accompanying drawing:

Embodiment 1

A kind of aircraft access is elastoplastic, including axle center compared with good position articulamentum compaction tool, the material of compaction tool Head 1 and tail portion 2 on same straight line, head 1 are cylindrical body, and the hole for holding rivet bar insertion, riveting are provided with along its axial direction Nail rod is fully inserted into hole, and the end on head 1 and the projection contacts of rivet and end size are along its axial direction to the side far from tail portion To successively decreasing；Tail portion 2 and riveting gun cooperate, and shape is similar to riveting card shape.

The form fit of the end face and protrusion of head and rivet projection contacts.

Embodiment 2

A kind of articulamentum compaction tool of aircraft access bad position, the material of compaction tool are elastoplastic, including axis The head 1 and tail portion 2 that the heart is not arranged on the same straight line, head 1 are bending cylindrical body, its axial direction is provided with appearance rivet bar and inserts The hole entered, rivet bar are fully inserted into hole, and the end on head 1 and the projection contacts of rivet and end size are along its axial direction to separate Successively decrease in the direction of tail portion；Tail portion 2 and riveting gun cooperate, and shape is similar to riveting card shape.

The form fit of the end face and protrusion of head 1 and rivet projection contacts.

Working principle: setting tail portion similar with riveting card shape is to guarantee that the compaction tool can be realized with riveting gun and match It closes, the hole of head setting is that the rivet or screw in order to match compaction tool with rivet bar, applied to different-diameter can be set The hole for setting different-diameter matches.

Because compaction tool is struck using riveting gun, and compaction tool material is flexible plastics, it is ensured that stress Stability not will lead to the deformation of part；The combination that original nut and dinking are replaced using compaction tool, when operation more It is convenient, shorten the production cycle.

In riveting (being spirally connected) operation for carrying out multilayer connection, according to riveting access, different compaction tools is selected.First will Rivet (screw) is put into the rivet hole produced, and is lived rivet (screw) rod set using the head of compaction tool, compaction tool tail Portion and riveting gun cooperate, and riveting gun beats the gap that can be eliminated between part, carries out riveting operation after removing compaction tool.

Above-described embodiment is only the preferred embodiments of the utility model, does not constitute limitations of the present invention.This Amplification that field those of ordinary skill is done on the basis of the utility model, deformation are in the protection scope of the utility model It is interior.
