Detailed Description
The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Referring to fig. 1, a multipoint pushing pin device includes a housing 1, a base 2, a piston seat 3, a piston 4, a pushing pin 5, an electrode plug 6, an initiating explosive column 7 and a booster explosive column 8; the base 2 is connected with the shell 1 through threads and presses the support lug 9 on the push pin shaft 5; the shell 1 is provided with a step for limiting the push pin shaft 5 to be completely pushed out; the piston seat 3 is connected with the shell 1 through threads, the piston 4 is arranged in the piston seat 3, and a limit pin 10 is arranged on the end face of the piston 4 close to the push pin shaft 5; an electrode plug 6, an initiating explosive column 7 and a booster explosive column 8 are arranged in the base 2, and the booster explosive column 8 is arranged at one side close to the push pin shaft 5.
The working principle of the multipoint marketing device in the embodiment is as follows:
before an ignition control signal comes, the push pin shaft 5 is limited by the shell 1 and cannot move, and the piston 4 is limited by the steering engine blade and the limiting block and cannot move; when an ignition control signal arrives, the electrode plug 6 or the electric detonator detonates the primary explosive column 7 and the booster explosive column 8 to generate high-pressure gas, the push pin shaft 5 is pushed, four support lugs 9 on the push pin shaft 5 are cut off, the push pin shaft 5 continues to move under the pushing of the high-pressure gas after the support lugs 9 are cut off, an air passage is opened, the high-pressure gas pushes the piston 4 to move, and the piston 4 further pushes the steering engine blades to move, so that the synchronous release of the steering engine blades is realized.
In one embodiment, the base 2 is provided with an electrostatic release mechanism 11, and the electrostatic release mechanism 11 is connected to the electrode plug 6.
In this embodiment, static electricity may be generated during the installation of the electrode plug 6 or when the multipoint pushing pin device vibrates, and the static electricity generated by the electrode plug 6 is transmitted to the base 2 through the static electricity releasing mechanism 11 before the ignition control signal does not arrive, so as to avoid the danger of the electrode plug 6 generating the electrostatic ignition initiating explosive column 7 and the booster explosive column 8.
In one embodiment, a cone seal is used between the electrode plug 6 and the base 2.
In this embodiment, the electrode plug 6 and the base 2 are sealed by a cone structure, so that the electrode plug 6 is more convenient to mount, and the electrode plug 6 and the base 2 are combined more tightly to achieve a good sealing effect.
In one embodiment, the base 2 is sealed to the housing 1 with a graphite seal ring 12.
In this embodiment, the graphite sealing ring 12 has a high temperature resistance, and can ensure that the air tightness between the base 2 and the housing 1 is maintained at a high temperature.
In one embodiment, the piston seat 3 and the housing 1 are sealed with a first silicone rubber sealing ring 13.
In one embodiment, the piston 4 and the piston seat 3 are sealed by a second silicone rubber sealing ring 14.
In one embodiment, the push pin shaft 5 and the housing 1 are sealed with a third silicone rubber seal 15.
In one embodiment, the number of the pistons 4 is several, and the pistons are uniformly arranged in the circumferential direction of the push pin shaft 5. As shown in fig. 1, the number of the pistons 4 is 4, theoretically, a plurality of pistons 4 may be designed, one may be used, or a plurality of pistons may be designed, and the pistons are specifically designed according to the structural size and the product requirements.
In one embodiment, the spacing pin 10 is made of a resilient material.
In this embodiment, the limit pin 10 has a certain elastic deformation, so that the vane of the steering engine can be in close contact with the piston 4.
The support lug 9 designed on the push pin shaft 5 can ensure the high overload requirement of the projectile body in the launching process, such as the axial direction of 23000g, and different overload requirements can be met by adjusting the size of the support lug 9. In the ignition process, the primary explosive column 7 and the booster explosive column 8 are ignited to generate high-pressure gas, the support lug 9 of the pushing pin shaft 5 is firstly cut off under the action of the high-pressure gas, then the pushing pin shaft 5 is pushed down, the high-pressure gas reaches the end face of the piston 4, the pressure is the same, the stress of the piston 4 is the same, and the release synchronism of the steering engine blades is ensured.
The invention can realize larger thrust in a smaller space, for example, the movement space of the piston 4 is 8mm, the movement space of the pushing pin shaft 5 is 4mm, the radial thrust of a single piston 4 is 50kg, and the axial thrust is 150kg, and the five directions, including the directions of four pistons 4 and a pushing pin shaft 5, are all pushed by the same gas, so the synchronism is better. The invention can adjust the thrust to the thrust pin shaft 5 and the piston 4 by changing the proportion of the primary explosive column 7 and the booster explosive column 8, thereby having higher adaptability. The power source of the invention adopts the ignition agent to generate high pressure, and has high reliability.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, and the scope of protection is still within the scope of the invention.
