Multifunctional pneumatic device of air guiding-type automatic machine

Abstract

The invention discloses a multifunctional pneumatic device of an air guiding-type automatic machine. The multifunctional pneumatic device of the air guiding-type automatic machine comprises a cylinder, a limiting pin, an air valve and a piston, wherein the air valve and the piston are both arranged in the cylinder; the air valve is located between the bottom of the cylinder and the piston and is used for partitioning the space between the piston and the bottom of the cylinder into two cavities; the limiting pin penetrates through the cylinder and the air valve in the radial direction and is used for limiting axial movement of the air valve; an air guiding hole is formed in the bottom of the cylinder and is used for enabling an air chamber in the cylinder to communicate with an air guidinghole in an acting object; when high-pressure air enters the bottom of the cylinder, the air valve is pushed to move towards the piston side and opens an air path to enable the cavity between the air valve and the piston to communicate with the air guiding hole; when the pressure of the acting object is decreased, the air valve moves towards the bottom of the cylinder under the effect of air in thecylinder to close the air path; and when the piston reversely moves to push the air valve, the air path is opened to enable the cavity between the air valve and the piston to communicate with the airguiding hole. The multifunctional pneumatic device of the air guiding-type automatic machine has a buffering function and a rebound reducing function.

Description

technical field [0001] The invention belongs to the field of air-guided automatic machines for weapons, in particular to a multifunctional pneumatic device for air-guided automatic machines. Background technique [0002] The air-operated automatic machine is a kind of machine that can withstand high temperature, high pressure and high-speed collision. In order to achieve a high rate of fire, it is necessary to increase the movement speed of the firing mechanism such as the latch body. Parts must have sufficient strength and rigidity. During the shooting process, these high-rigidity parts collide at high speed, which will produce a large displacement rebound, and this large displacement rebound is harmful to the reliability of most air-operated automatic machines, and needs to be effectively inhibition. [0003] The existing automaton pneumatic piston drive and anti-bounce technology are often separated, the pneumatic piston is used to drive the automaton to complete the sh...

Problems solved by technology

[0003] The existing automaton pneumatic piston drive and anti-bounce technology are often separated, the pneumatic piston is used to drive the automaton to complete the shooting cycle action by using the energy of gunpowder gas, and other special mechanisms are used to realize the re-entry firing process of the firing mechanism. buffer and reduce the bounce distance, these mechanisms are more complicated, have a short life, and require a large installation space, which is not conducive to the miniaturization and lightweight design of the air-guided automatic machine
