Abstract
The utility model relates to a fixture, concretely relates to a combined material lamination board anchor clamps for being struck by lightning it is experimental, mainly used is carrying out the ablate in -process centre gripping combined material lamination board of the experimental study of damage of aircraft combined material wallboard thunderbolt. The device comprises base, bracing piece, fixing base, sliding guide, clamp plate arm, briquetting, spring and adjusting bolt jointly, the utility model has the characteristics of simple structure presss from both sides tight reliably, install smallly, and weight is lighter, maintains the convenience to the be convenient for dismouting of combined material lamination board can effectually prevent that the excitation current from hitting the combined material test piece to fly.
Description
Technical field
The utility model relates to a kind of fixture, is specifically related to a kind of composite material laminated board fixture for lightning test, is mainly used in clamping composite material laminated board in the process of the experimental study carrying out technique for aircraft composite wallboard thunderbolt ablation damage.
Background technology
Along with the development of China's aircraft industry; many high new architectures continue to bring out; type aircraft uses fiber-reinforced resin matrix compound material (FiberReinforcedPolymer all in a large number; FRP) as structure material; if lack enough safeguard measures; after being struck by lightning, often there is damage and fracture more more significant than conventional airplane respective metal structure in these FRP structures.One of main Types of technique for aircraft composite wallboard lightning damage is ablation damage, its micromechanism of damage and safeguard procedures are one of directions of primary study, and one of main research means adopted carries out lightning test, in the process of experiment, because exciting current is very large, if do not take fixation, composite material laminated board will be easy to be hit fly, and produces potential safety hazard.When realizing similar functions, existing lightning test composite material laminated board clamp structure is more more complicated than the utility model, the installation and removal of composite material laminated board are more loaded down with trivial details, therefore, are badly in need of a kind of simple effective, service-strong lightning test composite material laminated board fixture.
Summary of the invention
Comparatively complicated in order to overcome existing lightning test composite material laminated board clamp structure, the deficiency that composite material laminated board installation and removal are comparatively loaded down with trivial details, the utility model provides a kind of novel lightning test composite material laminated board fixture, this device not only has the function of composite material laminated board reliable clamping, but also can carry out the installation and removal of composite material laminated board easily.
The technical scheme that the utility model adopts in order to technical solution problem is: this lightning test composite material laminated board fixture is by base, support bar, holder, rail plate, platen arm, briquetting, spring and adjustment bolt form jointly, concrete connected mode is: above base, be provided with 4 support bars, the top of support bar is connected with holder, holder is provided with 2 rail plates, rail plate is processed with width dimensions scope between 5 ~ 20mm, the chute of length dimension scope between 250 ~ 350mm, platen arm is arranged on rail plate by the wing bolt of specification between M3 ~ M20, extension spring is used to be connected between briquetting with platen arm, spring specification is between Φ 0.6 × 5 × 15mm ~ Φ 2.0 × 10 × 30mm, lightening hole is processed with in the side of briquetting, the blind hole of range of size between Φ 5 ~ Φ 20mm is processed with on briquetting top.In the process of carrying out lightning test, when needs clamping composite material laminated board, be rotated down the adjustment bolt above platen arm, make it move down, briquetting also moves down under the effect of adjustment bolt, the extension spring at briquetting two ends can play the effect preventing briquetting from rotating around adjustment bolt, thus ensure that the reliable clamping of composite material laminated board; When needs dismounting composite material laminated board, will adjust bolt reverse rotation, briquetting rises under the effect of extension spring restoring force, just composite material laminated board can be taken off afterwards.
The beneficial effects of the utility model are: structure is simple, and reliable clamping, device volume is little, lighter in weight, easy to maintenance, and is convenient to the dismounting of composite material laminated board, effectively can prevent exciting current from being hit by composite material laminated board and fly.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further.
Fig. 1 is assembling schematic diagram of the present utility model.
Fig. 2, Fig. 3, Fig. 4 are three-view diagrams of the present utility model.
In Fig. 1, platen arm 1, extension spring 2, briquetting 3, rail plate 4, holder 5, support bar 6, base 7, adjustment bolt 8.
Embodiment
In FIG, briquetting 3 is connected with platen arm 1 by extension spring 2, adjustment bolt 8 by the threaded hole above platen arm and the blind hole above briquetting 3 with the use of, by adjustment bolt 8 being tightened or is unscrewed the function realizing clamping and dismounting composite material laminated board, platen arm 1 is arranged on the top of rail plate 4 by the plain bolt that specification is M10 × 20, can according to the position of the size adjustment platen arm 1 of composite material laminated board specification during use, rail plate 4 is arranged on the top of holder 5 by the mode that pin connects, be processed with in the downside of holder 54 blind holes and support bar 6 with the use of, the downside of support bar 6 is arranged in the mounting hole of base 7 upper surface.
