Description
Technical field
The utility model relates to the shearing directed button automatic releasing device of a kind of substep, belongs to civil rocket bullet field.
Background technology
In civil rocket bullet transportation, play location, guiding and locking effect mainly through being positioned at the directed button of rocket projectile afterbody; In emission process, it coordinates with rocket gun tube helical guide groove, can ensure that rocket makes low-speed rotation after ejecting gun muzzle, to reduce motor power bias and the asymmetric adverse effect of body profile.
At present, civil rocket bullet is to precise guidance future development, and its inertial navigation system cannot normally work in missile rotation situation, for ensureing the suitability of guided rocket bullet and conventional belt helical guide groove gun tube, requires that directed button can Automatic-falling in emission process.
Although existing structure can realize the function that comes off of directed button, need before rocket bomb transmitting, manually go operation, not only extend launch time, and potential certain potential safety hazard.
Utility model content
The purpose of this utility model is that the function that comes off in order to solve traditional directed button structure needs manual operation, can extend launch time, there is the problems such as potential safety hazard, and provides that a kind of structure is reliable, the directed button automatic releasing device of function admirable.
The purpose of this utility model is achieved through the following technical solutions:
The shearing directed button automatic releasing device of a kind of substep of the present utility model, comprises locking screws, directed button, positioning tube, pull bar, block and blind nut;
The center of directed button has stepped throughhole, and directed button stepped throughhole upper end is processed with internal thread compared with the inwall of macropore;
Locking screws comprises lower end thread segment and upper end cylinder positioning section, has annular cut groove between the thread segment of locking screws and positioning section; External diameter and the directed button lower end of locking screws positioning section match compared with the internal diameter of aperture;
Positioning tube is columnar structured, and the internal diameter of positioning tube and the external diameter of body rear end match, and the front end outer wall of positioning tube extends outward the boss that external diameter is greater than gun tube afterbody, and this boss axially has the rectangular opening matched with the distributing position of directed button;
Back end of tie rod is that on width and positioning tube boss, the width of rectangular opening matches, the direction in the front end edge vertical panel face of pull bar has the locking screws connecting hole that aperture and locking screws positioning section external diameter match, and the rear end of pull bar has a block connecting hole along the direction in vertical panel face;
Positioning tube is enclosed within body rear end sidewall, pull bar inserts the rectangular opening on positioning tube boss, the outer panel face of locking screws connecting hole position, pull bar front end is welded and fixed directed button, locking screws is through the stepped throughhole at directed button center, its front end is threaded with the screwed hole of body sidewall, the hole internal thread connection blind nut that directed button stepped throughhole upper end is larger, prevents the locking screws after cutting off from outwards scurrying out; Back end of tie rod props up the interior plate face of block connection hole by the fixing block of screw, and the front end of a block is against body sidewall, makes pull bar parallel with elastomer axis.
Operation principle
During rocket projectile transport, directed button is fixed by locking screws and body sidewall thread, can bear circumferential impulsive force, completes the basic functions such as location and locking; And when launching, body preshoot under rocket engine thrust, the boss of positioning tube front end outer wall is subject to the stop of gun tube afterbody, cuts off the locking screws in directed button, thus reaches automatic unbuckling object.
Beneficial effect
Directed button automatic releasing device structure of the present utility model is simple, easy to assembly, on the basic functions such as guarantee original location, locking, when achieving transmitting, automatic unbuckling function, drastically increases the suitability of civilian guided rocket bullet, has important application value.
