Background
The quick-firing gun is a novel gun with the characteristics of light weight, high maneuverability, high firing speed and the like, plays an important role in modern wars, mainly depends on a gun automaton when in battle, can realize automatic firing of the gun, and plays an important role in the military field. The gun automaton mainly comprises a transmitting mechanism, a safety mechanism, a bullet supply and transmission mechanism, a recoil device and other key components, wherein when the gun is transmitted by the transmitting mechanism, gunpowder gas acts on a gun body, the gun body is enabled to move in the opposite direction to the movement direction of a projectile by the resultant force of a rearward gun bore, the gun body is enabled to move back to the standby position from a recoil termination position after the gun is transmitted, the gun body is enabled to move back to the standby position, the gun body is enabled to move back, the energy generated by the recoil motion is absorbed by the recoil device and converted into the energy of the recoil motion, and in the process, the recoil and the recoil of the gun are accurately controlled by the recoil device, so that the gun is ensured to always keep high-efficiency, stable and accurate performance in the shooting process.
The most commonly used high-buffering energy-absorbing self-adaptive compensation technology in the anti-squatting device is a spring buffering technology, the spring buffering technology absorbs and stores impact energy by utilizing elastic deformation of a spring, and the high-buffering energy-absorbing self-adaptive compensation technology is applicable to the anti-squatting device which needs simple control and low cost, but has limited buffering effect, is easy to generate rebound and resonance phenomena, and can cause fatigue and deformation of the spring after long-term use, so that the buffering effect is affected. Aiming at the problem, a controllable bidirectional damping braking buffer technology is proposed in the prior art, the controllable bidirectional damping braking buffer technology utilizes a controllable damping element to adjust the size and direction of damping force, optimize the buffer effect, and is suitable for an anti-squatting device needing accurate control and efficient buffer, for example, chinese patent application publication No. CN118936231A and publication No. 2024.11.12 discloses a continuous shooting recoil buffer device, the buffer device comprises a joint part, a guide rod and a cylinder assembly, the joint part is in butt joint with one end of the cylinder assembly and is used for being connected with a machine gun, one end of the guide rod is fixed with the joint part, the other end of the guide rod penetrates the cylinder assembly along the axial direction of the cylinder assembly, a piston cylinder and two elastic buffer pieces are also arranged in the cylinder assembly, the piston cylinder is fixedly sleeved on the guide rod, one ends of the two elastic buffer pieces are respectively positioned at two ends of the piston cylinder, one ends of the two elastic buffer pieces are respectively fixed with the piston cylinder, the other ends of the two elastic buffer pieces are respectively fixed with the cylinder assembly, the piston cylinder is positioned in the middle of the cylinder assembly and separates an inner cavity of the cylinder assembly into two cavities, the two cavities are respectively filled with the spiral grease grooves on the outer circumferential surfaces of the piston cylinder assembly, and the two spiral grease can be filled in the two spiral grease grooves are respectively filled in the piston cylinder, and the two spiral grease buffer grooves are respectively filled in the outer circumferential surfaces of the piston assembly; when the gun shoots, the recoil force applied to the joint part acts on the guide rod, the guide rod drives the piston cylinder to do the recoil movement, the elastic buffer piece absorbs the energy generated by the recoil movement and gradually stops the recoil of the guide rod, the elastic buffer piece converts the absorbed energy into the energy of the recoil movement, along with the release of the energy of the recoil movement, the guide rod reversely recoils to the initial position, the elastic buffer piece also resets to the initial position, the next shooting is ensured, the piston rod moves along with the guide rod in the whole recoil and recoil process, and damping grease in the spiral groove on the piston rod provides buffering force, so that the recoil and the recoil are stably carried out.
In the above-mentioned solution, it is not described what state the two elastic buffers are in the initial state, when the two elastic buffers are in the pre-compressed (pre-stretched) state in the initial state, the piston cylinder is kept stationary under the opposite restoring force of the two elastic buffers, but when the guide rod is subjected to the recoil force and moves in the axial direction of the cylinder assembly away from the joint, only the elastic buffer far away (close) from the joint is further compressed (stretched) to buffer the recoil force, but the elastic buffer near (far) from the joint is restored to the relaxed state from the compressed (stretched) state and then stretched (compressed), that is, the elastic buffer near (far) from the joint provides assistance to the recoil of the guide rod and then provides resistance, which is unfavorable for buffering and weakening the recoil force, resulting in a reduction in the firing accuracy of the gun, and in addition, when the guide rod is in the relaxed state, the guide rod is not subjected to the instantaneous recoil force, resulting in an instantaneous recoil force acting completely on the guide rod, resulting in a reduction in the impact line of the recoil force, resulting in a poor firing accuracy of the recoil device and the gun being subjected to the firing accuracy of the gun.
