Background technique
Composite material is widely used in high-tech areas such as aircraft manufacturings, and along with the continuous progress of composite material theoretical research and moulding process, the overall performance of composite material is greatly improved.But, due to by composite products shaping technical merit restriction and practical application need, composite products certainly exists certain structure parting surface and production breakdown interface, so inevitably there is a large amount of connection parts in composite structure, and the connection part of composite material is the integrally-built weak link of composite products always, affect giving full play to of composite material excellent specific property, therefore according to function and the service condition of composite products, analyse in depth the connection performance of composite material, rationally and neatly apply Connecting format and the method for composite material, improve composite products overall construction intensity, alleviate composite products overall weight, give full play to one of important channel of composite material excellent specific property.
The connection of current composite material thin wall pipe adopts bolt flange formula to connect, and it is that the flange being fastened by bolts two thin-wall circular tube ports connects to realize pipe that bolt flange formula connects, and this Placement exists following shortcoming:
1. have different strategies when mounting and dismounting bolt, needed time is long, and therefore installing/dismounting efficiency is lower;
2. need to carry out the secondary mechanical processing process such as perforate, except increasing labor intensity and except man-hour, also easy thin-wall circular tube to be caused damage, the reduction of thin-wall circular tube performance is even damaged;
3. flange width needed for is comparatively large, in the confined spaces such as wing, need could realize the connection of bolt flange formula, reduce the performances such as thin-wall circular tube flexural rigidity, and weight accounting is also large by reducing thin-wall circular tube diameter.
Visible, the joint efficiency of current composite material thin wall pipe is low, and effect is undesirable, needs to improve.
Summary of the invention
The object of the invention is the problems referred to above that the connection in order to solve current composite material thin wall pipe exists, provide a kind of clamp band type linkage structure for composite material thin wall pipe, its technological scheme is as follows:
A kind of clamp band type linkage structure for composite material thin wall pipe, it comprises two and waits to take over, flange is respectively arranged with at two craft port places to be taken over, two flange docking, around two flanges, two relative clips are set, two clips are connected by two or more bolt, are provided with and two friction tight draw-in grooves of flange inside two clips; In order to improve the anti-twisting property of linkage structure, arrange a plane be parallel to each other respectively in the relative both sides of each flange, accordingly, the shape at each draw-in groove two ends matches with described plane.
Beneficial effect of the present invention is: be connected firmly, and anti-twisting property is strong; Each parts can time processing shaping, avoid the secondary operations process such as perforate, connect simple and convenient, can not cause damage to thin-wall circular tube, make pipe fitting keep primary characteristic, improve dismounting efficiency and Security; Obviously can reduce the width of flange, the more current Placement of integral diameter obviously reduces, and is applicable in wing or other confined spaces.
