Abstract
The invention discloses a kind of clamping device of skin assemblies connection, including Wedge type eccentric swage one (1), Wedge type eccentric swage two (2), fast compactor (3) and flat grip device (4).The clamping device connected by the skin assemblies of the present invention, after eccentric swage and flat grip device, the pressure of wedge angle is resolved：In the presence of fast compactor, wedge eccentric swage wedge shape slowly enters the wedge angle position of product, and product component wedge angle position greatly enhances the cohesive force at wedge angle position, Wedge type eccentric swage enhances the pressure of curved surface wedge angle by uniform pressure.For the cementitious product component of such structure manufacture without waste product, product bonding quality is good, meets product tolerance requirement, and is not in degumming phenomenon.
Description
Technical field
The invention belongs to Aircraft tooling design and manufacturing field, and in particular to a kind of clamping dress of skin assemblies connection
Put.
Background technology
During aircraft skin, preceding floor skins front edges part shape at an acute angle, the region is mainly by several connectors
Splicing forms, and is connected referring to the existing product skin assemblies of Fig. 1, and it is glued splicing of the difficult point in covering corner.Existing fixture
Structure：A) covering terminations, are positioned with two clamps above fixture, above location-plate positioning compression covering；B), below fixture
It is made up of bottom plate and brill plate；C), the centre of fixture --- i.e. inside the acute angle of covering, with several pressing plates, two-sided pressing plate and positioning
Pin is formed, referring to Fig. 2 existing splicing clamp structure.Existing clamp structure uses Universal clamp tightly each face, and centre is again with soft
Cloth and cotton padding and compacting.Fixture uses upper and lower structures so, and center section structure is weaker, and major part and curved surface are put down
Face is glued poor, and wedge angle position causes covering wedge angle position poor, product degumming of bonding quality etc. occur because pressure is inadequate
Phenomenon.
The content of the invention
Instant invention overcomes the deficiencies in the prior art, there is provided a kind of clamping device of skin assemblies connection, mainly to being glued
Fixture center section is improved (i.e. inside the acute angle of covering), solves the problems, such as that above-mentioned center section pressure is inadequate.Each
On the premise of link all occurs without problem, the cementitious product component of such structure manufacture is without waste product, and product bonding quality is good, symbol
Product tolerance requirement is closed, and is not in degumming phenomenon.
In view of the above mentioned problem of prior art, according to one side disclosed by the invention, the present invention uses following technology
Scheme：
A kind of clamping device of skin assemblies connection of the present invention, including Wedge type eccentric swage 1, Wedge type eccentric swage two
2nd, fast compactor 3 and flat grip device 4；
Wedge type eccentric swage 1 and Wedge type eccentric swage 22 wedge skin assemblies from the left and right sides, will be oblique after the completion of splicing
Wedge-type eccentric swage 1 and Wedge type eccentric swage 22 unload from fixture；In order that wedge angle position is under pressure, Wedge type binder
The pointed part area of device should increase as far as possible, in order to avoid clamping device and a product connector on skin assemblies are mutual
Scratch, Wedge type eccentric swage is bonded with the contact surface of skin assemblies with the thick silica gel of 2mm；
The hold-down head of fast compactor 3 uses large-area planar circle hold-down head, increases lifting surface area, and hold-down head is used to compress
Wedge type eccentric swage.
Flat grip device 4 is made up of camber member, wearing plate and screw, and wearing plate is fixed on camber member, in the work of screw
Clamped with lower another product connector by product skin assemblies and skin assemblies.
The clamping device connected by the skin assemblies of the present invention, after eccentric swage and flat grip device, the pressure of wedge angle
Power is resolved：In the presence of fast compactor, eccentric swage (wedge shape) slowly enters the wedge angle position of product, product group
Part wedge angle position greatly enhances the cohesive force at wedge angle position, Wedge type eccentric swage enhances curved surface point by uniform pressure
The pressure at angle.Effect is fine after product component is glued, and operation is convenient, improves production efficiency.So as to reduce percent defective,
Substantially increase economic benefit.

Embodiment
The present invention is described in further detail with reference to embodiment, but the implementation of the present invention is not limited to this.
The clamping device of the skin assemblies connection of the present invention is as shown in figure 3, including Wedge type eccentric swage 1,2, fast-holding
Device 3 and flat grip device 4.
Wedge type eccentric swage structure：Because cementitious product modular construction is special (as shown in Figure 1), Wedge type eccentric swage is necessary
Dimidiation, eccentric swage could unload from fixture after the completion of splicing；In order that wedge angle position is under pressure, the wedge angle of eccentric swage
Position increases as far as possible, while is also contemplated that and can be unloaded from fixture.In order to avoid product connector I is scratched, Wedge type binder
Device is bonded with the contact surface of skin assemblies with the thick silica gel of 2mm.
The structure of fast compactor：On the basis of the standard CH-13008 (CH-SA-109015) of Tianjin producer, to pressure
Tight head point is improved, and using large-area planar circle hold-down head, increases lifting surface area, such as Fig. 4, shown in 5.
The structure of flat grip device：Because acute angle portion space is very small among product component, ten thousand power are not used, therefore by
Camber member, wearing plate and screw composition flat grip device, wearing plate is fixed on fixture, by product covering in the presence of screw
Clamped with product connector II, as shown in Figure 6.
During above-mentioned clamping device work, product is glued component first and is placed on by cover edges line on the bottom plate of splicing fixture
Face；Then each movable clamping and positioning device being glued in fixture superstructure is put into above covering and fastened；Again by two
Wedge type eccentric swage 1,2 is put into around product connector I, closes quick clamp device, two in the presence of quick clamp device
Wedge type eccentric swage 1,2 clamps covering and product connector I；Flat grip device 4 is finally arranged on the position shown in Fig. 3
On, covering is clamped with product connector II, this completes the clamping of whole product component, the laggard hot pressing of clamp
Tank, it is glued at certain temperature and pressure and completes.
Such a binding clasp improves by further genralrlization, such as using curved surface clamper structure as shown in Figure 8, can be with
Clamped for curved surface part, effect is also very good, and it is very strong to clamp versatility for other similar parts.
In the case where occurring without any problem, the splicing component produced meets wanting for product design for whole technological process
Ask, product qualification rate is at a relatively high.
