Description
Technical Field
The invention relates to an auxiliary device of a gun/cannon, in particular to a device for offsetting recoil of a barrel weapon.
Background
Recoil generated by shooting of a bullet by any barrel weapon (gun or cannon)? Is the pressure of the gunpowder gas to the bore bottom of the barrel. The recoil effect on the barrel can be divided into two periods: one is the internal ballistic period (i.e. the period during which the projectile moves within the barrel), and the second is the post-ballistic period (i.e. the instant at which the projectile leaves the bore). During the internal ballistic phase, the barrel is subjected to the bottom pressure and the frictional forces on the barrel as the projectile moves forward, which are significant, such as the blow-out that occurs when the bore is not fired cleanly, are substantially equal to the pressure of the propellant gas on the barrel bottom. This friction, which is equal to the force required to pull the projectile out of the bore during normal firing, greatly reduces the recoil during the inner trajectory, which is equal to the bottom pressure minus the friction of the projectile against the barrel. This is why the magnitude of the recoil has little effect on the accuracy of a single shot hit. Because the recoil is relatively small in displacement of the barrel due to the frictional force of the projectile against the barrel before the projectile exits the chamber. During the recoil, the recoil of the projectile as it exits the chamber suddenly increases because the frictional force of the projectile against the barrel suddenly disappears. The recoil is equal to the bore pressure, so the main recoil of the barrel weapon occurs at the end of the life, and therefore, in the case of a small arm, the recoil of the small arm, regardless of its size, has little effect on the accuracy of a single shot, but has a great effect on the accuracy of a burst shot.
Modern firearms can be divided into automatic weapons and non-automatic weapons. The non-automatic weapon is rigid latch, and the recoil strength conforms to impulse theorem, i.e. Ft is mv + m1v1F is recoil, t is action time, m is shot mass, V is shot velocity, m is shot mass1Is the quality of gunpowder, V1The gas velocity of the gunpowder. For automatic weaponry, there are several principles: (1) the gun is free bolt, (2) the gun barrel is retreated, (3) the air guide type, (4) the semi-free bolt type and the like. The greatest difference between automatic and non-automatic weapons is that, in the case of the free bolt, the recoil produced by the bolt assembly after the bullet has been fired is that the bolt assembly has extracted the cartridge case and, after ejection, the bolt assembly strikes the receiver as if it were struck backwards with a hammer, rather than in the internal trajectory and aftereffect, because the recoil energy and momentum are all applied to the bolt assembly, the bolt assembly will strike the receiver a short time later (not counting the force of the compression return spring on the gun). The other modes (2), (3) and (4) are slightly different from the free bolt, and the modes are equivalent to rigid locking before unlocking in an inner trajectory, namely, the shot moves in a barrel and is rigid locking, the unlocking time of guns of different models is different, but the guns can be unlocked at the end stage of the inner trajectory basically, the gun is the same as the free bolt in the later period of validity, and finally the bolt assembly completes unlocking, shell drawing, shell throwing and impact hammer pressing, and finally strikes a receiver, so that recoil is generated.
The earliest individual automatic weapons were the submachine guns that fired the handgun projectiles in order to reduce recoil, which had been reduced since first war i when soldiers' individual light arms evolved from non-automatic to automatic weapons (except, of course, heavy guns that stabilized the stock), such as the intermediate power rifle projectile first used in the second war in germany, and the small bore diameter 5.56mm rifle projectile first used in the transwar in the united states, primarily to reduce the recoil of the light arm so that it could be fired with some accuracy, certainly worse than single shot. And because the power of the bullet is reduced, the killing to the long-distance target is reduced, and the suppression to the enemy to the target in the battlefield is also reduced. In addition to the current methods of reducing recoil by reducing the power of a bullet, the rifle has not been satisfactory in terms of accuracy of recoil of a small caliber rifle with minimum recoil, so foreign countries have some new methods of reducing recoil of a small firearm, such as a rifle having a constant recoil, i.e. increasing the recoil spring length, increasing the bolt receiver distance, and making the bolt as unlikely to collide with the receiver, theoretically, the recoil force thereof corresponds to the hooke's law, i.e. F ═ KX, i.e. the recoil force is smaller the longer the recoil is, but in practice this principle is far from the ideal level, increasing the recoil spring distance and the length of the recoil spring tend to increase the receiver length, which increases the length and weight of the receiver, and the recoil force is smaller than the existing receiver due to the increase in the recoil spring length and the recoil distance of the bolt assembly, is unfavorable for the reliability under the severe battlefield environment. The other is the automatic balancing mode used on the tetris AK-107/108/109 assault rifle, which balances the impact impulse of the bolt to the receiver by leading out the powder gas to drive a balancing body to move forward, and the powder gas can apply pressure backward when driving the balancing body to move forward, so the automatic balancing mode can not reduce the energy of the backseat of the rifle and the impulse of the bolt assembly, but only reduces the impulse peak value of the bolt assembly when the bolt assembly impacts the receiver, namely when the bolt assembly impacts the receiver backward, the balancing body moves forward to offset a part of the impulse, thereby improving the running accuracy.
The recoil is reduced to generally installing the brake before the barrel of heavy-calibre rifle, but the brake has increased the shock wave of muzzle department when shooting, flare and raise dust, and muzzle/muzzle shock wave still can cause injury and damage to the supporting instrument equipment of artillery and user's hearing, and is also unfavorable to hiding the position.
In summary, the prior art cannot completely eliminate recoil, and the optimal technical scheme is to add a brake in front of the barrel, which can achieve an efficiency of about 60% at most, but the higher the efficiency, the greater the hazard, so that some countries, such as the united states, control the efficiency of the muzzle brake within 30%.
Disclosure of Invention
Aiming at the problem of recoil of the existing gun/cannon, the invention aims to provide a device for counteracting the recoil of a barrel weapon, which can eliminate the recoil of the gun/cannon in the recoil period and improve the continuous firing precision of the firearm.
In order to solve the technical problem, the device for offsetting recoil of a barrel weapon comprises a rear seat body, a balancing body and a transmission mechanism, wherein one end of the transmission mechanism is connected with the rear seat body, the other end of the transmission mechanism is connected with the balancing body, and the transmission mechanism is movably connected to a gun body/gun body or a receiver through a support shaft.
When the masses of the balance body and the rear seat body are approximately equal, under the transmission action of the transmission mechanism, the momentum of the rear seat body is the same as that of the balance body, but the directions of the rear seat body and the balance body are opposite, so that the momentum is mutually counteracted, the recoil force of the gun/cannon in the rear expiration date is eliminated, the rear seat body does not collide with the receiver any more, the gun/cannon is not influenced by the recoil momentum of the gun-holder assembly any more, and the continuous firing precision of the firearm is improved.
The invention has the technical effects that:
1. the recoil of gun/cannon in the period of validity can be completely eliminated, and the energy-absorbing device can be used for the conventional automatic weapons (assault rifle, light machine gun, heavy machine gun, submachine gun, small-caliber cannon and the like) and can also be theoretically used for large-caliber cannons after the energy-absorbing device is additionally arranged.
2. The firing precision of the gun can be greatly improved, if the gun is used on an assault rifle, the firing precision of the gun can exceed that of the existing light machine gun, because the light machine gun can have better precision only when in point firing, after more than three bullets are fired, the recoil can destroy the aiming of the gun, and the later bullets cannot hit the target. The existing heavy machine gun can reach or exceed the continuous shooting precision of the heavy machine gun, the weight of a gun frame of the existing heavy machine gun is reduced, the maneuvering capability is improved, but the shooting precision is not as good as that of the heavy machine gun in one battle, the heavy machine gun in one battle is not beneficial to maneuvering due to the large weight of the gun frame, but in defense, the recoil of the gun can be almost completely overcome due to the weight of the gun frame, and a target can be corrected according to the impact point of a bullet just like spraying water through a water pipe, so that the Makexin heavy machine gun in Germany in Sommer river battle causes six-ten-thousand-person casualties in the United England.
3. Reducing the shock wave hazard of a muzzle (muzzle) brake;
4. the reliability of the firearms in a severe battlefield environment is improved;
5. the weight of a powerful gun can be reduced, for example, a heavy gun does not need a heavy gun rack, and satisfactory continuous shooting precision can be achieved only by matching a bipod as a light gun.

If the rear seat of the rear seat body moves linearly, the first connecting rod 4 and the rear seat body 1 can be fixed into a whole; if the rear seat body moves in a fan shape during the rear seat, the first connecting rod 4 is movably connected with the rear seat body 1. Correspondingly, the balance body 2 and the second connecting rod 5 are also the same, if the rear seat body and the first connecting rod are fixed into a whole, the balance body and the second connecting rod are also fixed into a whole; if the rear seat body is movably connected with the first connecting rod, the balancing body is also movably connected with the second connecting rod.
In fig. 1, the transmission rod 10 is a rack, the second support shaft 7 is provided with a gear fixed on the second connecting rod 5, and the rack is engaged with the gear to drive a balancing body connected with the second connecting rod 5. Or the first supporting shaft 8 is provided with a gear fixed on the first connecting rod 4, the second supporting shaft 7 is provided with a gear fixed on the second connecting rod 5, and the gear is meshed with the gear to drive a balancing body connected with the second connecting rod 5. The main function of the transmission mechanism 3 is to transmit the energy of the rear base body 1, when the transmission mechanism is used for a light weapon, the link structure is more advantageous for increasing reliability due to the harsh environment protection, when the transmission mechanism is used for a large barrel weapon, such as a small-caliber artillery and a small-caliber artillery, and the rear base body has larger mass, the rack/gear and gear engagement structure is advantageous (the transmission ratio of the rack/gear and the gear is used, the moving speed of the balance body is far higher than that of the rear base body, the mass of the balance body is reduced, the momentum of the balance body is unchanged, and the weight of the weapon is reduced), and the priority can be given to the reduction.

As shown in fig. 3, the present embodiment is different from embodiment 1 in that:
the transmission mechanism 3 comprises a first connecting rod 4, a second connecting rod 5, a transmission rod 10 and a transmission auxiliary rod 14, the first connecting rod 4 and the second connecting rod 5 of the transmission mechanism are arranged in a V shape in an initial state, the first connecting rod 4 connected with the rear seat body 1 extends obliquely downwards, the second connecting rod 5 connected with the balance body 2 extends obliquely downwards relative to the first connecting rod 4, the extending end of the first connecting rod 4 is superposed with the tail section close to the extending end of the second connecting rod 5, and the first connecting rod 4 and the tail section are connected to a gun body/gun body or a receiver 11 in a rotating mode by jointly using a first supporting shaft 8; one end of a transmission rod 10 is connected with the extending end of the second connecting rod 5 through a second hinge shaft 9, the other end of the transmission rod 10 is connected with one end of a transmission auxiliary rod 14 through a third hinge shaft 13, the other end of the transmission auxiliary rod 14 is movably hinged on the tail section of the extending end of the first connecting rod 4 through a first hinge shaft 6, and the third hinge shaft 13 can reciprocate linearly in the casing.
The transmission mechanism 3 can be deformed into: the tail section close to the extending end of the first connecting rod 4 and the tail section close to the extending end of the second connecting rod 5 are overlapped in a crossed mode, and are connected to a gun body/a gun body or a receiver 11 in a rotating mode through a first supporting shaft 8; one end of a transmission rod 10 is connected with the extending end of the second connecting rod 5 through a second hinge shaft 9, the other end of the transmission rod 10 is connected with one end of a transmission auxiliary rod 14 through a third hinge shaft 13, the other end of the transmission auxiliary rod 14 is movably hinged to the extending end of the first connecting rod 4 through a first hinge shaft 6 (at the moment, the first hinge shaft 6 is located at the extending end of the first connecting rod 4 and below the first support shaft 8), and the third hinge shaft 13 can linearly reciprocate back and forth in the case.
Fig. 4 is a schematic view of the mounting position of the device of the present invention on the gun body.
The working principle of the invention is as follows:
taking the automatic principle of air-guide type gun rotation locking as an example, after a bullet is fired, under the action of gunpowder gas, a piston drives a gun frame to move backwards, the inclined plane of the gun frame drives the gun to rotate, so as to unlock, the gunpowder gas presses the bottom of a shell (namely, the bottom pressure of a chamber) to drive the gun to move backwards, after the bullet leaves the bore, a gun assembly compresses a re-entering spring to begin to complete actions of extracting the shell, ejecting the shell, pressing a reverse striking hammer and the like, and after the actions are completed, the gun assembly violently impacts the rear part of a receiver to consume redundant energy. At the moment, the gunlock component smashes towards the receiver like an iron hammer to generate recoil (actually, the recoil is energy, namely kinetic energy transmitted by the gunlock component), the gunlock component finishes actions of pushing a bullet into a chamber, locking and the like under the action of a recoil spring, and at the moment, a firing pin strikes the primer of the bullet to finish the firing of the next bullet.
Referring to fig. 1, after the bullet is fired, the bolt is unlocked, and then the bolt assembly (rear seat) moves backward under the action of the pressure at the bottom of the chamber, so as to drive the first link 4 to swing backward (clockwise in fig. 1) around the first support shaft 8, the first hinge shaft 6 on the first link 4 drives the transmission rod 10 to move backward, and the transmission rod drives the second link 5 and the balance body 2 to move counterclockwise (forward) by taking the second support shaft 7 as an axis through the second hinge shaft 9. Finally, after the gun assembly finishes shell drawing, shell throwing, impact hammer pressing and spring compressing and re-entering, the gun assembly (the rear seat body 1) collides with the balance body 2 which rotates anticlockwise at the time (the balance body 2 can be in any shape, the mass of the section from the second support shaft 7 to the balance body on the second connecting rod 5 is the same as that of the first connecting rod, the length of the section from the second support shaft 7 to the balance body is also the same, and the mass of the balance body 2 is the same as that of the rear seat body 1, so that the momentum of the movement of the balance body and the rear seat body is the same). Because the Momentum (MV) of the balance body is the same as the momentum of the rear seat body and the directions are opposite, the momentums are mutually offset, so that the bolt assembly (rear seat body) does not collide with the receiver any more, a gun branch is not influenced by the momentum of the rear seat of the bolt assembly any more, when the bolt assembly finishes propelling the bullet into the bore during the re-advancing process, the gun barrel rear part collides with the rear part of the gun barrel to generate a forward momentum, at the moment, due to the action of the transmission rod, when the rear seat body stops moving forwards, the balance body also stops moving backwards, a backward momentum is generated to balance the forward momentum, the two momentums have equal magnitudes and opposite directions, (at this time, the balance body and the receiver can also directly collide to generate the backward momentum to balance the forward momentum generated by the collision of the rear seat body and the rear part, so that the transmission rod 10 can be lighter, and the momentum of the transmission rod, the first hinge shaft 6 and the second hinge shaft 9 are reduced when the rear seat body collides with the rear end of the gun barrel, the balance 2 loads them) the momentum of the rear mount and the balance will cancel out completely when the firearm using the invention fires the cartridge.
In practical application, the first connecting rod 4 can be movably connected with the rear seat body 1, when the rear seat body moves backwards in a straight line, the balance body 2 is movably connected with the second connecting rod 5, and therefore the balance body 2 moves forwards in a straight line, the influence of centrifugal force on a gun is avoided, and the aiming line of the gun can be kept better.
The present invention is effective in reducing the momentum of the recoil of a barrel weapon when the gun/cannon is fired, why is the inventor said to completely eliminate recoil during the recoil? Because the invention can reduce nearly 90% of momentum of the back seat body, the rest can install the brake on the muzzle/muzzle, the efficiency of the brake does not need to be about 10% higher, so the harmfulness of the brake is greatly reduced, and under the combined action of the two anti-back seat devices, the firearm achieves the effect of no recoil.
In the practice of the present invention, the balance body can be mounted in front of the rear base body so that the length of the gun is not increased (see embodiment 2), the effect of the reverse rear base is as good as the structure of the front base body, of course, the rear base body and the balance body are both impacted with the casing to balance their momentum, the first support shaft and the second support shaft can be combined, the rear base body and the balance body share one rotating shaft (see embodiment 3), a transmission auxiliary rod and a third hinge shaft are added, and when the rear base body and the balance body move, the third hinge shaft linearly reciprocates back and forth in the casing. The device structure of embodiment 3 can also make the balancing body set in front of the back seat body, thereby not increasing the length of the gun.
The invention can also increase the reliability of the gun in the adverse circumstances, take the air-guide type automatic principle as an example, because the existing gun reduces the energy of the backseat for the shooting precision, the air-guide hole is generally not opened very much, the AK47 air-guide hole is bigger, although reliable, the burst precision is too poor, but the invention reduces the kinetic energy of the backseat according to the percentage, no matter how much kinetic energy of the backseat, there will be about 90% momentum offset, so the air-guide hole can be enlarged to guarantee the reliability, the remaining 10% momentum is solved by the muzzle/muzzle brake, the muzzle/muzzle brake is the prior art.
