Description
Technical field
The invention belongs to fuze safety mechanism technical field, and in particular to it is a kind of based on inertia memorial alloy constraint formula every
Disembark structure.
Background technology
Priming system is equipped with gunpowder or explosive, is burnt or exploded by being produced after environmental stimuli, with the gunpowder that ignites, ignition charge
Or do the disposable component of mechanical work and the general name of device.Interrupter is usually provided with priming system, it is made
Be make sensitive firer's element in Explosive sequence usually with next stage firer's element separation, it is ensured that fuse is accidental in its priming system
Misfire during preact, so as to avoid ammunition premature burst so that jeopardizing the safety of personnel and equipment.
The security of fuse be related to the demonstration of fuse, design, manufacture, inspection and acceptance, experiment, duties processing, using and
The life cycle managements such as explosive disposal.In safety period life-cycle of fuse, the effect of interrupter is to ensure fuse right
Arm-to-arm is in effective short-term/space of interacting goals, is safe condition in the case of remaining.
At present, conventional interrupter mechanism has slide block mechanism, lever type mechanisms and isolation rotor mechanism, wherein being turned with level
Minor interrupter is relatively conventional.Under normal circumstances, horizontal rotor formula interrupter utilizes torsion spring, clockwork spring (disc spring) or other
Spring, with less axial dimension, is adapted to the small occasion of axial dimension requirement, and level as the motive power of mechanism kinematic
Rotator type interrupter has larger releasing isolation corner, can ensure that flame proof security generally.But, it is existing
Horizontal rotor formula interrupter there is also certain defect, its defect be mainly grouped as it is following some.First, when interrupter is protected
After danger releases and moved in place, interrupter does not have lock function, under vibration, easily causes interrupter dislocation,
Explosive train is ultimately resulted in align not exclusively；Secondly, the two-stage safety piece Heterogeneous Permutation of horizontal rotor formula interrupter can cause
Mechanism size is larger, unreasonable to space utilization；Again, horizontal rotor formula interrupter usually not effectively utilizes the ring on bullet
Environment information (such as fly overload, centrifugal force, Aerodynamic Heating), and the driving of two-stage safety piece needs consumption fuse or missile power supply,
Energy dissipation is caused, and security is relatively low.Drawbacks described above causes the application of horizontal rotor formula interrupter to be subject to certain restrictions,
Security and practicality to interrupter have a certain impact, it is impossible to fully meet the safe handling of fuse.
The content of the invention
For the disadvantages described above or Improvement requirement of prior art, the invention provides a kind of memorial alloy based on inertia about
Beam formula interrupter, wherein the setting insured by using two-stage, is provided with larger releasing isolation corner, it is ensured that usually every
Quick-fried security, and interrupter has lock function after motion in place, can ensure that under vibration in state in place, it is ensured that
The reliability of detonation, lifts the security and practicality of fuze mechanism.
To achieve the above object, formula is constrained there is provided a kind of memorial alloy based on inertia according to one aspect of the present invention

The latch ends for memorial alloy pin removal corresponding with second blind hole are inserted locking the peace in the secure state
The pin hole of total state；
During arm-to-arm is converted under rotor is driven from safe condition, the inertial elements part is driven
And depart from from the 3rd blind hole and make it that the inertial elements part is integrally placed in first blind hole, correspondingly,
The latch ends of the memorial alloy pin removal are driven to be departed from from the pin hole, and then the rotor can be rotated by driving
Certain angle so that the accommodating hole for passing fiery part and the detonation transmission part is aligned, and first blind hole and the latch
Hole align and so that one end of the inertial elements part is embedded in the pin hole to lock the arm-to-arm, so as to can realize
The arm-to-arm is transformed into from safe condition and locks the arm-to-arm.
As a further improvement on the present invention, arc groove is offered on the rotor, for being led for rotor rotation direction
To and limit the rotational angle of rotor.
As a further improvement on the present invention, on cross section the arc groove two ends and rotor hole center line institute
The angle that the angle of composition need to be rotated when being converted to arm-to-arm from safe condition with rotor is identical.
As a further improvement on the present invention, on cross section the arc groove two ends and rotor hole center line institute
The angle of composition is 75 °~135 °.
As a further improvement on the present invention, it is further opened with being used to house locking member on the end face of rotor correspondence body
The 4th blind hole, for housing locking member, correspondingly, corresponding ball pin hole is offered on the body；
The locking member includes Lock spring and ball pin, and the Lock spring is in contraction state in the secure state,
The rotor hole end contact of the ball pin end and the body, rotor from safe condition turn to arm-to-arm when, described the
Four blind holes are just aligned with the ball pin hole, i.e., the Lock spring compressive state of described locking member is released, and ball pin insertion is described
So as to lock the arm-to-arm in ball pin hole.
As a further improvement on the present invention, the inertial elements part includes inertia cylinder and inertial spring, the inertia
One end of cylinder offers the groove for fixing described inertial spring one end；
In the secure state, the inertia cylinder is placed in the 3rd blind hole on the side end face of rotor one, described
The other end of inertial spring is placed in first blind hole on the body；The rotor turns to pending from safe condition
In state procedure, the inertial spring is in compressive state and the inertial elements part is integrally embedded in first blind hole；
When the rotor turns to arm-to-arm, first blind hole is aligned with the pin hole on the rotor, and the inertia cylinder is embedded
To lock the arm-to-arm in the pin hole.
As a further improvement on the present invention, the memorial alloy pin removal includes pin, limit spring, pressure spiral shell, housing
With memorial alloy sleeve；
The pin is T-shaped structure, and its front end is the latch ends of the memorial alloy pin removal, and the limit spring is arranged
