Abstract

The invention discloses an air canon with an adjustable variable-capacity high-pressure cavity, which belongs to the technical field of air shots. The external high-pressure cavity of the air cannon consists of a high-pressure cavity and a capacity-adjustable mechanism set. The capacity-adjustable mechanism set is structurally characterized in that a movable screw component is mounted on a screw support, a hand wheel component is mounted on the movable screw component, the front of the movable screw component penetrates through the rear wall of the external high-pressure cavity to be integrally connected with a piston in the high-pressure cavity, and the front wall of the external high-pressure cavity is provided with a high-pressure air through hole. The air cannon has the advantages that shortages or defects of existing air cannon due to fixed capacity of the high-pressure cavity can be overcome, initial volume of the high-pressure cavity can be changed by increasing or reducing capacity of the external high-pressure cavity, movement speed of shots in a shot tube can be adjusted within a certain range to realize continuous loading of low acceleration of different shots, and high impact speed and impact acceleration can be generated to meet the requirement of realizing high shot impact speed within a limited air pressure range. The air cannon with the adjustable variable-capacity high-pressure cavity is worthy of application and popularization.

Description

1. Technical field [0001] The air cannon with an adjustable volume high-pressure cavity disclosed by the present invention belongs to the technical field of air cannons, and specifically relates to an air cannon with an external high-pressure cavity with an adjustable volume. Setting the high-pressure chamber can change the initial volume of the high-pressure chamber in the air cannon, thereby changing 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. Air cannon equipment is required.
