Abstract
The utility model relates to a multi -functional test piece clamping device for surge test, mainly used are at the in -process centre gripping combined material lamination board test piece that carries out aeronautical composite material surge test ( impulse voltage test or impulse current test ), thereby it flies to cause the potential safety hazard to avoid the test piece to be hit when suffering great impact force. This clamping device comprises base, spiral lifting sleeve, spiral lifter, backup pad and quick assembly disassembly anchor clamps jointly to simple structure presss from both sides tight reliably, install smallly, and weight is lighter, and it is convenient to maintain, and the dismouting of combined material lamination board test piece is very convenient, and the in -process impulse voltage that can effectually prevent in the experiment or impulse current encourage to hit the combined material lamination board and fly.
Description
Technical field
This utility model relates to a kind of multi-functional specimen holder device for surge test, it is mainly used in the process carrying out aviation composite surge test (impulse voltage test or impulse current test) and clamps composite material laminated board test specimen, it is to avoid test specimen is hit when suffering greater impact power to fly thus causing potential safety hazard.
Background technology
Development along with China's aircraft industry; many high new architectures continue to bring out; type aircraft have employed carbon fiber enhancement resin base composite material (CarbonFiberReinforcedPolymer all in a large number; CFRP) as structure material; if lacking enough protective measures; after being subjected to impact electric current or surge voltage, these CFRP structure often occur than the significantly more damage of the metal structure of conventional airplane and destruction.Aviation composite one of damage main Types of generation after being subjected to impact electric current and surge voltage damages for ablation, its damage mode and mechanism and safeguard procedures are one of directions of primary study, the main research means adopted at present is by surge test, in the process of experiment, owing to rush of current and voltge surge are very big, if therefore not taking fixation, composite material laminated board will be easy to be hit fly, and there is potential safety hazard.When realizing similar functions, the structure of existing surge test specimen holder device is more increasingly complex than this utility model, the installation and removal of composite material laminated board test specimen 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
In order to overcome existing surge test specimen holder apparatus structure complex, the deficiency that the installation and removal of composite material laminated board test specimen are relatively complicated, this utility model provides a kind of multi-functional specimen holder device for surge test, this device can effectively clamp the aviation composite laminate carrying out surge test, and carries out the installation and removal of composite material laminated board easily.
In order to solve technical problem, this utility model be the technical scheme is that this clamping device includes fast assembling-disassembling fixture, gripper shoe, spiral lifting bar, spiral lifting sleeve, base, concrete connected mode is: base is attached by buckle structure and spiral lifting sleeve, the processing of spiral lifting sleeve lining has female thread, and with Surface Machining have externally threaded spiral lifting bar with the use of, this clamping device can carry out altitude mixture control by spiral lifting sleeve and spiral lifting bar, and adjustable-height is in the scope of 100mm～300mm.The top of spiral lifting bar is connected with gripper shoe by buckle structure, gripper shoe can carry out the rotation of 360 ° around spiral lifting bar, being fixed with 4 fast assembling-disassembling fixtures by wing bolt in gripper shoe, the clamping force scope that fast assembling-disassembling fixture can provide is between 300N～1200N.In the process carrying out surge test, when needs clamp composite material laminated board test specimen, the handle of fast assembling-disassembling fixture is depressed, the chuck making fast assembling-disassembling fixture compresses composite material laminated board, and cause losing clamping action by utilizing " dead point principle " to guarantee that the handle of fast dismantling fixture will not loosen because being subject to external interference, thus ensure that the reliable clamping of composite material laminated board.When, after off-test, during dismounting composite material laminated board test specimen, the handle of fast assembling-disassembling fixture being lifted and can easily composite material laminated board test specimen be taken out.
The beneficial effects of the utility model are: simple in construction, reliable clamping, and device volume is little, lighter in weight, easy to maintenance, and the dismounting of composite material laminated board test specimen is very convenient, it is possible to effectively prevent surge voltage or dash current excitation in the process of experiment from being hit by composite material laminated board and flying.
