Abstract
The invention discloses a clamping device connected with a skin assembly. The clamping device comprises a tapered wedge type material press I (1), a tapered wedge type material press II (2), a quick compactor (3) and a planar clamp (4). According to the clamping device connected with the skin assembly, by the adoption of the material presses and the planar clamp, pressure at a sharp corner is solved; under the action of the quick compactor, the tapered wedge shape of the tapered wedge type material presses slowly enters the sharp corner portion of a product; the sharp corner portion of the product is uniformly stressed, so that the cohesion of the sharp corner portion is greatly enhanced; the tapered wedge type material presses increase the pressure on the sharp corner of a curved surface. No cemented product assemblies manufactured by such a structure are rejected; the product cementing quality is high; the product tolerance requirement can be met; meanwhile, the phenomenon of cementing failure can be avoided.
Description
Technical field
The invention belongs to Aircraft tooling design and manufacture field, be specifically related to the clamping device that a kind of skin assemblies connects.
Background technology
In aircraft skin process, front floor skins front edges part acutangulates shape, and this region forms primarily of several connector splicing, and connect see the existing product skin assemblies of Fig. 1, it glueds joint difficult point splicing in covering bight.Existing clamp structure: a), fixture above locate covering termination, above location-plate positioning compression covering with two clamps; B), be made up of base plate and brill plate below fixture; C), the centre of fixture---namely the acute angle of covering is inner, forms, see the existing splicing clamp structure of Fig. 2 with several pressing plate, two-sided pressing plate and alignment pin.Existing clamp structure adopts ten thousand power to clamp each face, and centre uses soft cloth and cotton padding and compacting again.Fixture adopts levels structure so, and mid portion structure comparison is weak, and it is poor that major part and curved surface plane are gluedd joint, wedge angle position due to pressure inadequate, cause covering wedge angle position to occur the phenomenons such as bonding quality is poor, product comes unstuck.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, the clamping device that a kind of skin assemblies connects is provided, mainly improving glueing joint fixture mid portion (namely the acute angle of covering is inner), solving the problem that above-mentioned mid portion pressure is inadequate.Under the prerequisite that links does not go wrong, the cementitious product assembly that such structure manufactures is without waste product, and product bonding quality is good, meets product tolerance requirement, and there will not be degumming phenomenon.
Consider the problems referred to above of prior art, according to an aspect disclosed by the invention, the present invention by the following technical solutions:
The clamping device that a kind of skin assemblies of the present invention connects, comprises Wedge type eccentric swage one (1), Wedge type eccentric swage two (2), fast compactor (3) and flat grip device (4);
Wedge type eccentric swage one (1) and Wedge type eccentric swage two (2), from left and right sides wedging skin assemblies, unload from fixture after having gluedd joint by Wedge type eccentric swage one (1) and Wedge type eccentric swage two (2); In order to make wedge angle position be under pressure, the pointed part area of Wedge type eccentric swage should strengthen as far as possible, and in order to avoid scratching with the product connector of on skin assemblies, the silica gel that the contact surface 2mm of Wedge type eccentric swage and skin assemblies is thick is fitted;
Fast compactor (3) hold-down head uses the circular hold-down head of large-area planar, and strengthen lifting surface area, hold-down head is for compressing 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, is clamped by another product connector on product skin assemblies and skin assemblies under the effect of screw.
By the clamping device that skin assemblies of the present invention connects, after adopting eccentric swage and flat grip device, the pressure of wedge angle is resolved: under the effect of fast compactor, eccentric swage (wedge shape) slowly enters the wedge angle position of product, product component wedge angle position is subject to uniform pressure, the cohesive force at wedge angle position is strengthened greatly, and Wedge type eccentric swage enhances the pressure of curved surface wedge angle.After product component glueds joint, effect is fine, and operative is convenient, improves production efficiency.Thus reduce percent defective, substantially increase economic benefit.

Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
The clamping device that skin assemblies of the present invention connects as shown in Figure 3, comprise Wedge type eccentric swage 1,2, fast compactor 3 and flat grip device 4.
Wedge type eccentric swage structure: due to cementitious product modular construction special (as shown in Figure 1), the necessary dimidiation of Wedge type eccentric swage, having gluedd joint rear eccentric swage could unload from fixture; In order to make wedge angle position be under pressure, the wedge angle position of eccentric swage is strengthened as far as possible, also will consider unload from fixture simultaneously.In order to avoid product connector I scratches, the silica gel that the contact surface 2mm of Wedge type eccentric swage and skin assemblies is thick is fitted.
The structure of fast compactor: on standard C H-13008 (CH-SA-109015) basis of Tianjin producer, improved hold-down head part, uses the circular hold-down head of large-area planar, strengthens lifting surface area, as Fig. 4, shown in 5.
Flat grip device: because acute angle portion space in the middle of product component is very little, ten thousand power are not used, and therefore form flat grip device by camber member, wearing plate and screw, and wearing plate is fixed on fixture, under the effect of screw, product covering and product connector II are clamped, as shown in Figure 6.
During above-mentioned clamping device work, first product is gluedd joint assembly and be placed on the substrate glueing joint fixture by cover edges line; Then the clamping and positioning device of each activity of glueing joint in fixture superstructure is put into above covering fastening; Be put into around product connector I by two Wedge type eccentric swages 1,2, close quick clamp device again, and under the effect of quick clamp device, covering and product connector I clamp by two Wedge type eccentric swages 1,2; Finally be arranged on the position shown in Fig. 3 by flat grip device 4, covering and product connector II are clamped, and this completes the clamping of whole product component, the laggard autoclave of clamp, has gluedd joint at certain temperature and pressure.
This kind of binding clasp improves through further genralrlization, such as, use curved surface clamper structure as shown in Figure 8, and can also be used for curved surface part clamping, effect is also very good, very strong for other similar part clamping versatility.
When there is not any problem in whole technological process, the splicing assembly produced meets the requirement of product design, and product percent of pass is quite high.
