Abstract
The utility model provides a fastener fatigue test anchor clamps and lower liner cover thereof, fastener fatigue test anchor clamps overlap the body including the lower anchor clamps that are provided with the lower liner cover, lower liner cover including lower liner, and lower liner cover body includes the big footpath section that path section and vestibule terrace and path section link to each other, is equipped with suspended structure in the path section, suspended structure have when packing up so that the path section by packing up the station and expanding so that the lower liner cover hangs in case its expansion station that drops on the anchor clamps under in the back of packing into in the supreme corresponding mounting hole of anchor clamps of packing into down. In when assembly, make earlier during suspended structure is in the corresponding mounting hole of the anchor clamps of packing up the station so that the path section is packed into down, and then make suspended structure be in to expand the station to make the lower liner cover hang on anchor clamps down, and then carry out the clamping of fastener, danger that the lower liner cover did not drop, messenger fatigue test is safer.
Description
Technical field
This utility model relates to a kind of securing member fatigue test clamper and lower lining thereof.
Background technology
Along with greatly developing of field of aerospace in recent years, securing member is more and more applied in field of aerospace.The fatigue behaviour of securing member is one of most important performance of securing member, is related to flight safety, and the securing member especially for some big specifications needs to carry out fatigue test with nut.Need during fatigue test with fixture, securing member to be clamped, fatigue test clamper generally comprises fixture and lower clamp, being respectively equipped with lining and lower lining on upper and lower fixture, securing member to be measured just can be tested after needing to complete assembling with upper lining, lower lining and nut.Fatigue test is usually with lower lining and is made up of with the big footpath section being connected with path section by step surface path section, during assembling, by manually descending lining to make path section load in the corresponding installing hole of lower clamp the most from the bottom to top in tow, then completing the fixing of securing member and nut, described step surface is as contact the stress surface carried with lower clamp.Owing to the specification of securing member is relatively big, its lower lining specification used is the biggest, relies on and is susceptible to, when manually lifting, the situation that lower lining comes off, thus brings potential safety hazard to process of the test.
Utility model content
The purpose of this utility model is to provide one lower lining, holds caducous problem with securing member when assembling solving lower lining of the prior art；The purpose of this utility model also resides in a kind of securing member fatigue test clamper using this lower lining of offer.
In order to solve above-mentioned technical problem, in this utility model, the technical scheme of lower lining is:
A kind of lower lining of securing member fatigue test clamper, including lower bush body, lower bush body includes path section and the big footpath section being connected by step surface with path section, path section is provided with suspended structure, and described suspended structure has when packing up so that path section loads packing up station and launching after said fitting so that lower lining hangs on lower clamp in case its expansion station come off in lower clamp the corresponding mounting hole from the bottom to top.
Described suspended structure is made up of at least one suspender being rotatably connected in path section.
Described suspender is rotatedly connected with path section by spinning screw on path section end face.
Described suspender is for hanging sheet.
Described suspender has at least two and is evenly distributed.
In this utility model, the technical scheme of securing member fatigue test clamper is:
A kind of securing member fatigue test clamper, including the lower clamp being provided with lower lining, lower lining includes lower bush body, lower bush body includes path section and the big footpath section being connected by step surface with path section, path section is provided with suspended structure, and described suspended structure has when packing up so that path section loads packing up station and launching after said fitting so that lower lining hangs on lower clamp in case its expansion station come off in lower clamp the corresponding mounting hole from the bottom to top.
Described suspended structure is made up of at least one suspender being rotatably connected in path section.
Described suspender is rotatedly connected with path section by spinning screw on path section end face.
Described suspender is for hanging sheet.
Described suspender has at least two and is evenly distributed.
The beneficial effects of the utility model are: arrange suspended structure in path section, suspended structure has packs up station and launches station, so when assembling, first make suspended structure be in and pack up station so that path section loads in the corresponding installing hole of lower clamp, make suspended structure be in expansion station the most again, so that lower lining hangs on lower clamp, carry out the clamping of securing member the most again, the danger that lower lining does not drop, makes fatigue test safer.

Detailed description of the invention
nullThe enforcement of securing member fatigue test clamper is such as shown in Fig. 1 ~ Fig. 7，Including upper fixture 1 and lower clamp 2，On、Lining it is respectively equipped with on lower clamp，Described lining includes the lower lining 3 being located on lower clamp 2，Lower lining 3 includes lower bush body 31，Lower bush body 31 includes path section and the big footpath section being connected by step surface with path section，Path section is provided with suspended structure，Described suspended structure has when packing up so that path section loads packing up station and launching after said fitting so that lower lining 3 hangs on lower clamp 2 in case its expansion station come off in lower clamp 2 the corresponding mounting hole from the bottom to top，The upper surface of path section offers two screwed holes 34 symmetrical relative to lower lining 3 axial line，Screwed hole 34 is fixed with screw 32，Described suspended structure includes the suspension sheet 33 being rotatedly connected by screw 32 and path section.
During fatigue test assembling, the suspension sheet 33 in path section is packed up, path section is loaded from the bottom to top in the corresponding installing hole of lower clamp 2, rotate suspension sheet 33 and make lower lining 3 be suspended on lower clamp 2, carry out the clamping of securing member the most again, fatigue test can be carried out.
Described suspended structure has packs up station, so could successfully load in the corresponding installing hole of lower clamp by path section, also have expansion station simultaneously, lower lining the most just can be made to hang on lower clamp, facilitate the assembling of fatigue test.Suspender has at least two and is evenly distributed, and is two in a preferred embodiment and is symmetrical arranged, stablizing of such guarantee suspension.Suspender is rotatedly connected with path section by spinning screw on path section end face, and such suspender is detachable, can be dismantled when not needed or facilitate it to change when suspender damages.
In other embodiments of securing member fatigue test clamper: suspender can be with only one of which；Suspender can also be axle or bar；Suspender can also be that the axle rotated around it by being fixed on the confession suspender of path section end face is rotatedly connected with path section；Suspended structure can not be rotary type, it is possible to is the latch stretched out that can move linearly being hidden in path section.
The enforcement of the lower lining of securing member fatigue test clamper is such as shown in Fig. 2 ~ Fig. 7, and the lower lining of securing member fatigue test clamper is identical with the lower lining described in above-mentioned securing member fatigue test clamper embodiment, is not described in detail in this.
