Problems solved by technology

[0004] The invention provides a bullet holder applied to 105mm smoothbore gun test, which solves the problem that when there is a gap between the shell of the bullet holder and the bottom of the projectile in the existing device, during the firing process, the bullet holder is subjected to the high pressure of the gunpowder gas, and the bullet holder is shot at a very short distance. It will produce a large acceleration, impact on the bottom of the bullet, and cause the bullet holder to disintegrate in the bore, resulting in the failure of the test. The gun bore is damaged by debris and cannot adapt to the requirements of firing intensity under different overloads.

Embodiment 1

[0028] see figure 1 , the present invention is applied to a bullet holder for 105mm smoothbore gun test, comprising a bullet holder shell 1, a projectile 2 is inserted inside the bullet holder shell 1, and a gas-tight ring 3 is threadedly connected to the bottom of the bullet holder shell 1, so as to increase the sealing performance of the device, To prevent leakage, the end of the gas-closing ring 3 far away from the bullet holder shell 1 is connected with an end cover 4 by screws, and the end cover 4 is used to enhance the pressure resistance of the tail of the bullet holder shell 1, and the end of the bullet holder shell 1 close to the gas-closing ring 3 is clamped with a support plate 5. The support plate 5 can be compressed by the air-closing ring 3, so that the support plate 5 is further attached to the bottom of the projectile.

[0029] In the existing device, there is a gap between the bullet holder shell 1 and the projectile 2. During the process, the high pressure of...

Embodiment 2

[0031] see Figure 2-4 , further improvements have been made on the basis of Example 1:

[0032] In this embodiment, the bullet holder shell 1 is composed of three bullet holder pieces made of 120° aluminum alloy. By using the air-tight ring 3 to be threadedly connected with the bullet holder shell 1, it is convenient for the three bullet holder pieces to be engaged with each other, and it is convenient for the bullet holder to snap together. Fixing and recycling of the support shell 1.

[0033] In order to increase the gas-holding effect of the device, the diameter of the tail of the gas-closing ring 3 is 20mm larger than the caliber of the gun, and the gas-closing ring 3 made of nylon material can be deformed and bent to fill the gap when it is under pressure.

[0034] In this embodiment, four screws are threadedly connected with an aluminum alloy end cap 4, which is used to increase the extrusion resistance of the nylon shell 1 and the gas-closing ring 3, and prevent the b...

Embodiment 3

[0036] see Figure 5-6 , further improvements have been made on the basis of Example 1:

[0037] In order to make the support plate 5 and the bottom of the bullet further close, the inside of the gas-holding ring 3 is fixedly connected with a protrusion, and the gas-holding ring 3 is clamped inside the support plate 5 through the protrusion. It can be changed to meet the launch tightness requirements under different overloads.

[0038] In this embodiment, in order to facilitate the better separation of the bullet holder casing 1 after it exits the muzzle, a cutting slit is provided at the connecting part between the gas-closing ring 3 and the bullet holder casing 1 at intervals of 20°, so that the connection part of the bullet holder casing 1 is under pressure. Can break quickly and separate quickly.

[0039] Concretely, when the present invention is used, at first the tail of the projectile 2 is fixed with a conical air-tight ring 3, and the bullet holder shell 1 is compose...

Abstract

The invention discloses a projectile support applied to a 105mm smoothbore gun test. The projectile support comprises a projectile support shell, wherein a projectile is inserted into the projectile support shell; the bottom of the projectile support shell is in threaded connection with an air closing ring; the end, away from the projectile support shell, of the air closing ring is connected with an end cover through a screw; the end, close to the air closing ring, of the projectile support shell is connected with a supporting disc in a clamped mode; and the end, close to the supporting disc, of the projectile is connected with a limiting ring in a clamped mode. Through a conical nylon limiting ring, it can be guaranteed that the projectile bottom is completely attached to the bottom of the projectile support shell; the thickness of the supporting disc can be adjusted to meet the launching intensity requirement, and the overall mass of the projectile can be reduced; a bulge with the same diameter as the supporting disc is arranged in the middle of the air closing ring and can press the supporting disc; the maximum diameter part of the tail part of the air closing ring has a variable width so as to adapt to the launching sealing requirements under different overloads; the end cover fixed at the tail part of the air closing ring can increase the launching tightness and improve the launching reliability; and a seam is cut at the connecting part of the air closing ring and the projectile support shell at an interval of 20 degrees, so that the projectile support shell can be better separated after going out of a muzzle.

Description

technical field [0001] The invention relates to the technical field of artillery experiment equipment, in particular to a bullet holder applied to a 105mm smoothbore gun test. Background technique [0002] A 105mm smoothbore gun is a gun with a caliber of 105 mm. There is no rifling in the barrel. The smoothbore gun has a higher pressure and has the ability to fire armor-piercing shells with high muzzle velocity. The manufacturing cost of the smoothbore gun is lower than that of the rifled gun. [0003] When there is a gap between the shell of the existing bullet holder and the bottom of the projectile, during the firing process, the bullet holder is subjected to the high pressure of the gunpowder gas, which will generate a large acceleration in a short distance, impacting on the bottom of the bullet, so that the bullet holder is in the chamber. The internal disintegration caused the test to fail, and the inside of the gun was damaged by debris, which could not meet the requ...
