Description
Technical field
The present invention relates to a kind of blanking cover release device.
Background technology
It is test engine performance when guided missile empty station is tested, typically uses disposably throw to put formula blanking cover and block and start
Tail spout.According to carrier aircraft mount point Airflow Environment characteristic and safety requirements, mode must be put from suitable blocking cover structure and throwing, and
Blanking cover trajectory emulation is carried out, to ensure that blanking cover throws the security put.But during practical flight, the qigong of carrier aircraft mount point
Environment is complicated, and blanking cover trajectory simulation process can not consider unexpected factor comprehensively, it is impossible to predicts that blanking cover is thrown and puts state pair
The potential danger of carrier aircraft.
Accordingly, it is desirable to provide a kind of new technical scheme solves the above problems.
The content of the invention
The technical problem to be solved in the invention is to provide a kind of non-throwing and puts formula blanking cover release device.Both blanking cover locking had been met
When block engine tail nozzle functional requirement, realize again blanking cover release when not to carrier aircraft produce security implication.
To solve the technical problem of the present invention, the technical solution adopted by the present invention is：
A kind of blanking cover release device, the blanking cover release device includes blanking cover fold mechanism, the initial retaining mechanism of blanking cover and blocked up
Lid is deployed into position locking mechanism, the blanking cover fold mechanism include left active hinge, left driven hinge, right active hinge, it is right from
Dynamic hinge, upper rail and lower guideway, between the left active hinge, left driven hinge and right active hinge, right driven hinge it
Between using straight pin be flexibly connected, the upper rail and lower guideway by mechanically connect with base be connected；The blanking cover is initial
Retaining mechanism includes blasting bolt and base, and the blasting bolt makes left passive blade, left active blade reliable by fastener
In initial fold state；The blanking cover, which is deployed into position locking mechanism, includes stage clip and distribution, and the stage clip, distribution are fixed on bottom
On seat, after blanking cover initial retaining mechanism release, left active hinge, right active hinge are deployed into certain angle by torsion spring around the shaft
After degree, promote in the presence of stage clip, in the left active hinge of wedging, the bellmouth of right active hinge, the left active page of locking blanking cover
Piece, right active hinge.
The upper rail, the rectangular channel of lower guideway make the cylindrical end of left passive blade, right passive blade only along rectangle flute length
Spend direction motion.
The blanking cover release device of the present invention mainly uses slider-crank mechanism principle, devises two symmetrical crank blocks
Mechanism, locks slave arm, to reach the initial lock state of blanking cover in initial position；When slave arm unlocks state, with
Torsion spring is power, driving master arm rotation, so that slave arm band movable slider is moved along the rail, when reaching predeterminated position, locking
Master arm, completes blanking cover release conditions.
Beneficial effects of the present invention：The principle that the blanking cover release device is used is simple, practical, meets closure and starts
The function of tail spout, and put because that need not throw, the security implication to carrier aircraft is eliminated, and it is reusable, shorten the lead time
And reduce development cost.

Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.Following examples are merely to illustrate this hair
It is bright, it is not limited to protection scope of the present invention.
Shown in Fig. 2, Fig. 3 a, Fig. 3 a, Fig. 5, blanking cover release device of the invention, the blanking cover release device is folded including blanking cover
The initial retaining mechanism of mechanism, blanking cover and blanking cover are deployed into position locking mechanism, and blanking cover fold mechanism includes left active hinge 16, Zuo Cong
Dynamic hinge 15, right active hinge 12, right driven hinge 13, upper rail 10 and lower guideway 14, two sets of driving and driven hinges are left and right right
Claim to set, self-movement do not interfere with each other, between left active hinge 16, left driven hinge 15 and right active hinge 12, right driven page
It is flexibly connected between piece 13 using straight pin 9, so as to form rotary gemel, upper rail 10 and lower guideway 14 are by mechanically connecting
It is connected with base 1；The initial retaining mechanism of blanking cover includes blasting bolt 8 and base 1, and blasting bolt 8 is made left driven by fastener
Blade 15, left active blade 16 are reliably in initial fold state；Blanking cover is deployed into position locking mechanism including stage clip 21 and promoted
11, stage clip 21, distribution 11 are fixed on base 7, after blanking cover initial retaining mechanism release, left active hinge 16, right active page
Piece 12 17 is deployed into after certain angle around the shaft by torsion spring 18, is promoted 11 in the presence of stage clip 21, is wedged left active hinge
16th, in the bellmouth of right active hinge 12, the left active hinge 16 of locking blanking cover, right active hinge 12.
Shown in Fig. 3 a and Fig. 3 a, upper rail 10, the rectangular channel 20 of lower guideway 14 make left passive blade 15, right passive blade 13
Cylindrical end only moved along the length direction of rectangular channel 20.
Shown in Fig. 4, by taking the blanking cover fold mechanism of left side as an example：The one end of torsion spring 18 is fixed on base 1, and the other end is fixed on a left side
In active hinge 16, the power source of mechanism deploying is used as；Left driven hinge 15 is connected with left active hinge 16 by straight pin 9,
Rotary gemel is formed, wherein left driven hinge 15 is slave arm, left active hinge 16 is master arm；Upper rail 10, lower guideway 14
Rectangular channel constrain the movement locus of left driven hinge 15, make the side-to-side movement only along along rectangular channel of its cylindrical end, i.e., left driven page
The cylindrical end of piece 15 constitutes the prismatic pair and revolute of slave arm；It is connected by base 1 with body and is used as blanking cover fold mechanism machine
Frame part.
The initial retaining mechanism of blanking cover is mainly made up of blasting bolt 8 and base 1, blasting bolt 8 by fastener make it is left from
Movable vane piece 15, left active blade 16 are reliably in initial fold state.
Blanking cover folds into the retaining mechanism that formula is then promoted using typical spring by position locking mechanism.In Fig. 4, it is at label 19
Engine tail nozzle.
Shown in Fig. 1, blanking cover release device of the invention mainly uses slider-crank mechanism principle, devises two symmetrically
Slider-crank mechanism, locks slave arm 3, to reach the initial lock state of blanking cover in initial position；When slave arm 3 unlocks
During state, using torsion spring as power, driving master arm 2 rotates so that slave arm 3 with movable slider 4 along frame 1（Containing guide rail）Fortune
It is dynamic, when reaching predeterminated position, lock to be formed at master arm 2, label 5 and slide block movement direction is pointed at driving moment, label 6, from
And complete blanking cover release conditions.
Therefore, left active hinge 16, left driven hinge 15, rotating shaft 17, straight pin 9, upper rail 10, lower guideway 14 constitute one
Individual slider-crank mechanism, torsion spring 18 is used as power source.
Workflow is as follows：, will be stifled by the blasting bolt between mechanism and body when blanking cover is in initial fold state
Lid reliably lock onto initial position, to realize that blocking cap mechanism blocks the function of engine tail nozzle；Sprayed when engines tail must be released
During mouthful sealed condition, mechanism receives instruction, blasting bolt unblock, and active hinge links in the presence of torsion spring and driven hinge and made
Sliding block is along guide rail directed movement, after expansion in place, is moved away from engine tail nozzle position, releases engine tail nozzle sealed condition,
After promote and lock blanking cover under spring force, realize the folding release of blanking cover.
