Description

Bolt separation unit of pyro separation device {BOLT SEPARATION UNIT OF PYROTECHNIC MECHANISM DEVICE}

The present invention relates to a bolt separation unit of a pyro separation device.

A pyro-separator is a device that separates bolts by operating internal components due to the high pressure generated during the combustion of gunpowder. It is used in the aviation and space industries to separate projectiles, etc. or to control equipment.

Looking at the conventional operating principle, when a signal is applied, gunpowder burns and creates pressure, causing the piston and cylinder to move. This makes it possible to release the split that holds the initial separation bolt, and the internal pressure causes the separation bolt to be released. will be dislodged.

In this process, when pressure is applied to the separation bolt, a force is generated in the direction in which the separation bolt separates (axial direction), and at the same time, due to the contact shape between the separation bolt and the split, the split is split in a direction perpendicular to the direction of movement of the separation bolt (radial direction). ) is configured to generate a pushing force to release the split.

At this time, since the split must be moved under conditions where the friction force with the separating bolt and housing in contact increases, a problem occurs in which the split cannot be released smoothly. If the split is not released smoothly, the split becomes stuck between the housing and the separation bolt, causing a problem in which the separation bolt cannot be separated properly.

Figure 1 is a cross-sectional view schematically showing the bolt separation unit of the pyro separation device according to an exemplary embodiment of the present invention, and Figures 2 and 3 show the split assembly being restrained in the bolt separation unit of the pyro separation device of Figure 1, respectively. It is a drawing schematically showing the restrained state and the restrained state, and FIGS. 4 and 5 are drawings schematically showing the restrained state and the restrained state of the split assembly according to different embodiments, respectively, and FIGS. 6 and FIG. 7 is a diagram schematically showing the state in which the protrusions of the split and the cylinder are coupled and assembled.

Referring to the drawings, the bolt separation unit 1 of the pyro separation device according to an exemplary embodiment of the present invention includes a housing 10, a cylinder 20, a pressure cartridge 30, a piston 40, and a split assembly ( 50) may be included.

The housing 10 includes a first accommodating hole 11 having a certain diameter inside and a second accommodating hole 12 that is enlarged to a larger diameter at the end of the first accommodating hole 11 to form a step. can be provided. That is, two receiving holes 11 and 12 of different sizes are formed penetrating in the longitudinal direction, and a step is formed between the receiving holes 11 and 12 according to the difference in diameter size.

The housing 10 is fixed to one side (rear) of the main body (M) where the insertion hole (Ma) into which the separation bolt (B) is inserted is formed, and the first receiving hole (11) and the second receiving hole (12) are connected to the insertion hole (12). It can be arranged to lie on the same axis as (Ma).

The cylinder 20 has a hollow tube structure, is disposed in the first receiving hole 11 and the second receiving hole 12, and can slide along the axis.

One end of the cylinder 20 may be disposed within the second receiving hole 12, and the other end of the cylinder 20 may be disposed to protrude to the outside of the housing 10.

One end of the cylinder 20 may be provided with a protrusion 21 that protrudes toward the inner surface of the second receiving hole 12 and catches on a step during sliding movement to restrict movement.

The pressure cartridge 30 is mounted on the other end of the cylinder 20, and can be arranged so that the part containing the gunpowder is inserted into the cylinder 20.

The pressure cartridge 30 can generate pressure inside the cylinder 20 by an applied signal. The cylinder 20 can move in the opposite direction (rearward) to the separation bolt (B) due to the generated pressure.

The piston 40 is mounted within the hollow of the cylinder 20 and may be placed adjacent to the pressure cartridge 30.

The piston 40 moves toward the separation bolt (B) by the pressure generated when the pressure cartridge 30 is operated and can press the separation bolt (B) toward the other side (forward) of the main body (M).

The split assembly 50 may be disposed adjacent to the rear of the main body (M) within the second receiving hole (12).

The split assembly 50 is provided to move in a radial direction perpendicular to the axis (12) It can be arranged to surround and restrain the rear end of the separation bolt (B) inserted inside.

As shown in Figure 10, as the cylinder 20 moves in the opposite direction to the piston 40 due to the pressure generated when the pressure cartridge 30 operates, the split assembly 50 is released from restraint, and thus the split assembly ( 50) has a spreading structure and moves in the radial direction to release the restraint around the rear end of the separation bolt (B), thereby allowing the separation bolt (B) to be separated.

Referring to Figures 2 and 3, the split assembly 50 may include a split 51 and an elastic body 52 composed of a plurality of dividing members.

The splits 51 have an arc shape, and a plurality of splits 51 may be spaced apart from each other and arranged to form a ring shape.

The split 51 may have a connecting pin 53 protruding from one side. Additionally, a connection hole 54 into which the connection pin 53 is inserted may be provided on one side of the split 51 provided with the connection pin 53 and on one side of the other split 51 opposite to the other side.

The connection pin 53 may have a triangular, square, or other polygonal cross-sectional shape. Corresponding to the shape of the connection pin 53, the connection hole 54 may also have a triangular, square, or other polygonal cross-sectional shape. Therefore, when the connection pin 53 is inserted into the connection hole 54, the individual splits 51 can maintain movement in a state parallel to the rear of the main body M without rotating.

The elastic body 52 is disposed between each split 51 to elastically connect the splits 51 to each other. The elastic body 52 may be arranged to surround the circumference of the connection pin 53.

The elastic body 52 may include, for example, a coil spring, a leaf spring, etc., but is not limited thereto.

As shown in FIG. 2 , as the split assembly 50 is fitted between the protrusions 21 of the cylinder 20, the elastic body 52 is compressed and the gap between the splits 51 is narrowed to maintain a confined state.

And, as shown in FIG. 3, as the cylinder 20 moves by the operation of the pressure cartridge 30, the elastic body 52 comes out between the protrusions 21 of the cylinder 20 and returns to its original state when the restraint is released. It is restored and due to the force, the gap between the splits 51 widens and spreads and moves in the radial direction.

Therefore, as the split assembly 50 moves in the radial direction in a spreading structure, the restraint around the rear end of the separation bolt B is released, so that the separation bolt B can be separated from the split assembly 50.

Figures 4 and 5 show another embodiment of the split assembly.

Referring to the drawings, the split assembly 50' may include a split 51 composed of a plurality of dividing members and a pneumatic cylinder 55.

The splits 51 have an arc shape, and a plurality of splits 51 may be spaced apart from each other and arranged to form a ring shape. The pneumatic cylinder 55 is disposed between each split 51 to connect the splits 51 to each other.

The split 51 has a pneumatic cylinder 55 connected to one side, and a piston of the pneumatic cylinder 55 is attached to one side of the other split 51 facing one side of the split 51 to which the pneumatic cylinder 55 is connected. Rod 56 may be connected.

As shown in Figure 4, as the split assembly 50' is fitted between the protrusions 21 of the cylinder 20, the piston rod 56 is compressed within the pneumatic cylinder 55, thereby narrowing the gap between the splits 51. will remain incarcerated.

And, as shown in FIG. 5, as the cylinder 20 moves by the operation of the pressure cartridge 30, the piston rod 56 is compressed in a state in which it escapes between the protrusions 21 of the cylinder 20 and is released from restraint. It protrudes from the pneumatic cylinder 55 due to the force of air and spreads and moves in the radial direction as the gap between the splits 51 widens.

Therefore, as the split assembly 50' moves in the radial direction in a spreading structure, the restraint around the rear end of the separation bolt B is released, so that the separation bolt B can be separated from the split assembly 50'.

Meanwhile, as shown in FIGS. 6 and 7 , the inner peripheral surface of the protrusion 21 and the outer peripheral surface of the split 51 that contact each other may have a structure inclined to each other in order to restrain and release the split assembly 50.

When assembling the pyro separation device 1, the split assembly 50 needs to be assembled from a spread state to a compressed state again, and a force to compress the elastic body 52 is applied to the protrusion 21 of the cylinder 20. ) must be sandwiched between them.

It is possible to assemble the split assembly 50 with the cylinder 20 in a compressed state using a separate assembly jig, but in this case, there is a disadvantage in that a separate assembly jig must be provided.

As in the present invention, when the inner peripheral surface of the cylinder protrusion 21 and the outer peripheral surface of the split 51 are configured to have an inclined structure, the split 51 slides during the assembly process by pushing the cylinder 20 toward the main body M. and moves to the initial compressed restraint position and can be fitted between the protrusions 21 of the cylinder 20.

Accordingly, assembly between the split assembly 50 and the cylinder 20 can be facilitated. In addition, since the split 51 has an asymmetrical shape before and after, if it is assembled in the opposite direction, assembly with the cylinder 20 becomes impossible, thereby preventing defects in the pyro separation device 1 due to incorrect assembly of the split assembly 50. You can.

In this way, according to the present invention, the split assembly 50 restraining the separation bolt B is restrained in a compressed state by the cylinder 20, and when the restraint is released as the cylinder 20 moves, the elastic It moves in the radial direction on its own due to the restoring force or the force of compressed air, making it possible to smoothly release the restraint on the separation bolt (B).

Therefore, the problem of the separation bolt (B) not being released smoothly due to conventional friction can be eliminated, thereby improving the reliability of the device.

In addition, by improving the shape of the contact portion between the cylinder 20 and the split 51, assembly is improved, and defective products of the pyro separation device 1 that may occur during the assembly process can be prevented.

Referring to Figures 8 and 9, the bolt separation unit of the pyro separation device according to another embodiment of the present invention will be described.

Figure 8 is a diagram schematically showing another embodiment of the cylinder and the split in the bolt separation unit of the pyro separation device according to an exemplary embodiment of the present invention, and Figure 9 is a view showing the protrusions of the split and the cylinder being fastened and assembled in Figure 8. This is a diagram schematically showing the state.

The bolt separation unit 2 of the pyro separator according to the embodiment disclosed in FIGS. 8 and 9 has a basic configuration with the bolt separator unit 1 of the pyro separator according to the embodiment disclosed in FIGS. 1 to 7. is the same. However, since there is a difference in that the housing 10 is provided with a guide pin 13 and the split 51 is provided with a guide groove 57, the differences will be mainly explained below.

Referring to the drawings, the housing 10 may be provided with guide pins 13 arranged radially on the inner surface of the second receiving hole 12.

The guide pin 13 may extend from the inner surface of the second receiving hole 12 toward the axis line there is.

Additionally, the guide pins 13 may be arranged at regular intervals along the inner surface of the second receiving hole 12 corresponding to the position of each split 51.

The guide pin 13 may have a triangular, square, or other polygonal cross-sectional shape.

The split 51 may be provided with a guide groove 57 connected to the guide pin 13. The guide groove 57 may be formed by recessing the outer peripheral surface of the split 51 to a predetermined depth.

The guide groove 57 may have a triangular, square, or other polygonal cross-sectional shape corresponding to the guide pin 13.

Therefore, when the guide pin 13 is inserted and connected to the guide groove 57, the individual splits 51 are parallel to the rear of the main body M without rotating or buckling toward the piston 40. Reciprocating movement can be maintained along the radial path implemented by (13).

Meanwhile, a slit 21a may be formed on the protrusion 21 of the cylinder 20 in contact with the outer peripheral surface of the split 51 to prevent interference with the guide pin 13. Therefore, in the process of assembling the cylinder 20 by pushing it toward the main body M, the guide pin 13 is accommodated in the slit 21a of the protrusion 21, thereby preventing interference between the cylinder 20 and the guide pin 13. This can prevent problems in which the cylinder cannot move.
