[0034] Embodiment 2. High-pressure cavity with adjustable volume for air cannon

[0035] The specific structure of the high-pressure cavity with adjustable volume for the air cannon of this example can be Figure 1 to Figure 8 etc. jointly show that the air cannon of this example has the difference between the high-pressure chamber with adjustable volume and the air cannon of embodiment one: 1. the rear of the disc-shaped air cannon of this example Six axial circular through-holes 31 are evenly arranged on the circumference of the wall 29 in the radial direction L (n is selected as 6 in this example). 2. The structure of the handwheel assembly 1 in this example is: six or four cylindrical spoke rods 18 . The air cannon of this example uses the variable-volume high-pressure chamber that is not described, and is the same as that described in Embodiment 1, and will not be repeated.

Embodiment 3

[0036] Embodiment 3. High-pressure cavity with adjustable volume for air cannon

[0037] The specific structure of the high-pressure cavity with adjustable volume for the air cannon of this example can be Figure 1 to Figure 8etc. jointly show that the air cannon of this example is different from the high-pressure chamber with adjustable volume of the air cannon of embodiment one and embodiment two: the disc-shaped air chamber of this example 7, or 8, or 9, or 10, or 11, or 12 axial circular through holes 31 are evenly arranged on the circumference of the radial direction L of the back wall 29 . The air cannon of this example uses the high-pressure cavity with adjustable volume all the other not described, all the same as described in embodiment one, embodiment two, no longer repeat.

Abstract

The invention discloses a high-pressure cavity with adjustable capacity for air cannon, belonging to the technical field of the air cannon. The external high-pressure cavity consists of a high-pressure cavity and a whole set of a capacity adjustable mechanism, wherein the whole set of the capacity adjustable mechanism is characterized in that: a movable screw assembly is mounted on a screw bracket and is provided with a hand wheel assembly; the front part of the movable screw assembly passes through the back wall of the external high-pressure cavity and is connected with a piston in the high-pressure cavity to form a whole body; and a high-pressure air inlet-outlet is arranged on the front wall of the external high-pressure cavity. The high-pressure cavity disclosed by the invention has the advantages in that: the defects or disadvantages caused by the fixed capacity of the conventional high-pressure cavity of the air cannon can be overcome by the external high-pressure cavity with the adjustable capacity for the air cannon; an original volume of the high-pressure cavity is changed by increasing or decreasing the capacity of the external high-pressure cavity, so that a movement speed of a cannon ball in a cannon pipe can be adjusted within a certain range; different cannon balls are continuously loaded at a low acceleration speed to generate a higher impact speed and an impact acceleration speed, so as to meet a requirement of the wider impact speed of the cannon ball within a limited air pressure range. The technical scheme disclosed by the invention is worthy of adoption and popularization.

Description

1. Technical field [0001] The volume-adjustable high-pressure cavity for an air cannon disclosed by the present invention belongs to the technical field of air cannons, and specifically relates to an external high-pressure cavity with an adjustable volume for an air cannon. Through this external high-pressure cavity, the Changing the initial volume of the high-pressure chamber in the air cannon changes the initial volume of the compressed air in the high-pressure chamber, thereby changing the initial energy of the air cannon and the initial acceleration of the projectile. 2. Background technology [0002] In the field of national defense and industrial production, some need to do impact collision tests, such as the research on the anti-shock energy of acceleration sensors, such as the impact sensitivity test of gunpowder, such as the impact resistance test of storage testers, such as the impact simulation test of projectiles, etc. To use the air cannon to load the device. ...
