Detailed description of the invention
Upon reading the detailed description of non-limiting embodiments with reference to the following drawings, other feature of the invention,
Objects and advantages will become more apparent upon:
Fig. 1 is the working principle diagram of Gu Dan mechanism variable cross-section magnesium ribbon tripper of the present invention.
Specific embodiment
The present invention is described in detail combined with specific embodiments below.Following embodiment will be helpful to the technology of this field
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill of this field
For personnel, without departing from the inventive concept of the premise, various modifications and improvements can be made.These belong to the present invention
Protection scope.
As shown in Figure 1, Gu Dan mechanism variable cross-section magnesium ribbon tripper of the present invention mainly by magnesium ribbon 1 carry out Curve Machining and
At, cooperate Gu Dan mechanism on the threaded rod 5, one of locking cylinder 4, one of clamping element 3, one of a four-quadrant clamping element 2, one
Big 6, the one small connecting pin of connecting pin, 7, one big shaft block ring, 8, small shaft block rings 9 form one.In transport and storage
When, there is fixed function to guided missile and launching tube；When guided missile normal ignition, there is unlock effect to guided missile and launching tube；Guided missile
Accidental ignition when gas generator is not lighted a fire, only also has unlock effect under guided missile pulling force.
One end of magnesium ribbon 1 is connect by big connecting pin 6 with one end of four-quadrant clamping element 2, and big shaft block ring 8 is located at four-quadrant
On the other end for limiting clamping element 2, the other end of magnesium ribbon 1 is connect by small connecting pin 7 with one end of clamping element 3, small shaft block ring 9
On threaded rod 5, the other end of clamping element 3 is connect with one end of locking cylinder 4, and the other end of threaded rod 5 and locking cylinder 4 connects
It connects so that it is convenient to connect and position.
The both ends diameter of magnesium ribbon 1 is identical and is greater than the mid diameter of magnesium ribbon 1, easy to use in this way.
Four-quadrant clamping element, clamping element, locking cylinder, threaded rod, big connecting pin, small connecting pin, big shaft block ring, small axis are used
Retaining ring constitutes a lever mechanism, can be by the load transported Scaling that guided missile is subject to, and is loaded into magnesium ribbon two sides, convenient for control
Stress.
The magnesium ribbon is processed by magnesium alloy, is carried out Curve Design to cross section, is obtained the suitable load model of the magnesium ribbon
It encloses, its role is to: when guided missile normal transport, the variable cross-section curve of magnesium ribbon is designed, it will not when guided missile being made to encounter accidental loads
It is pulled off；It is only disconnected in pre-position under guided missile pulling force effect due to designing the variable cross-section curve of magnesium ribbon when accidental unlocking
It splits and reaches unlock effect.
The unlocking method of Gu Dan mechanism variable cross-section magnesium ribbon tripper of the present invention includes following two parts:
First part, normal release, comprising the following steps:
Step 1, when MISSILE LAUNCHING, gas generator will light a fire, and eject high temperature, high-speed fuel gas, and guided missile receives combustion gas
Thrust moves upwards, and makes magnesium ribbon simultaneously by certain pulling force effect by Gu Dan mechanism.
Step 2, the jet flow that gas generator projects have high-pressure jet, act on magnesium ribbon in directly washing away.
The temperature of step 3, lower chamber is instantly increased, and the mechanical property of magnesium ribbon suddenly reduces.
Step 4, by guided missile draw, combustion gas blow, high temperature burn three kinds effect make section magnesium ribbon moment disconnect, pre-tighten masterpiece
It completes to unlock with Xia Gudan mechanism.
Second part, when accidental unlocking, comprising the following steps: guided missile accidental ignition has upward movement, thus right
Magnesium ribbon only has pulling force effect.By the Curve Design of magnesium ribbon, magnesium ribbon can satisfy index demand in terms of normally consolidating bullet, but unexpected
Under ignition conditions, magnesium ribbon can be pulled off moment under guided missile pulling force effect in predetermined position, so that unlock avoids accident.
In conclusion variable cross-section magnesium ribbon of the invention is linked together by lever mechanism and bullet mechanism body admittedly, guided missile is just
Often when transport, the variable cross-section curve of variable cross-section magnesium ribbon ontology is designed, will not be pulled off when guided missile being made to encounter accidental loads；When leading
When bullet needs normal transmission, using the physical characteristic of variable cross-section magnesium ribbon ontology itself, guided missile is drawn, combustion gas is blown, high temperature burns three kinds of works
It is unlocked with lower fracture；When guided missile normal transmission, while gas generator occurs unexpected when can not light a fire, and designs variable cross-section magnesium ribbon
The variable cross-section curve of ontology, only in pre-position, fracture reaches unlock effect under guided missile pulling force effect.The present invention is closed with magnesium
Gold is fabricated to the magnesium ribbon of variable cross section, the Fracture Force of magnesium ribbon is designed according to different model, to reach unlock purpose.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited to above-mentioned
Particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims, this not shadow
Ring substantive content of the invention.
