Description
The present invention relates to the automatic machine of automatic weapons such as rifle, big gun, is one can subtract the machine frame device that hits frequency reducing automatically.
One, in the prior art, automatic machine subtracts and hits buffer unit and have bufferings such as various cylindrical, annular, dish-shaped buffer springs or combination shape spring buffer and bakelite, rubber, fibre plate, friction block, hydraulic pressure, gas to subtract collision device.Play the deceleration firearms that reduce the shooting frequency in the prior art just like U.S. Browning, John Moses 1918A2 formula, advance growth percussion time formula frequency reducing reducing gear on formula frequency reducing reducing gear and the AKM of Soviet Union assault rifle escapement pendulum extension percussion formula deceleration frequency reducing mechanism and the Finland LS-26 formula light machine gun etc. again than the extension of four kinds of machine guns such as Browning, John Moses 30 formulas, Fa Haqikaisi T11 formula, FM24 Saudi Arabia Lip river formula.Buffering and reducing gear in the above-mentioned prior art (seeing " automatic weapon and ammunition design manual " that National Defense Industry Press published in 1977), subtract to hit and separate with frequency reducing, with automatic machine be not one, all be non-tight add external device in addition, exist complex structure, defective such as fault rate height under the special environment.
Two, play the virtuous MP-43 formula tommy gun of gas regulation effect in the prior art by change air guide chamber original volume, it is to strengthen or dwindle air guide chamber original volume and regulate by ad hoc adjuster, the shortcoming that exists is to increase part such as adjuster, and made air guide chamber leading portion many and adjuster between fit clearance and gas leakage.
The objective of the invention is to overcome weak point in the above-mentioned all kinds of prior art, and a kind of principle uniqueness is provided, simple and reasonable, the frequency reducing machine frame is hit in replaceable general subtracting.
Purpose proposed by the invention is realized by following technical scheme:
One, the present invention is former machine frame loss of weight, institute's loss of weight quantitative change is the inertia weight of slowing down, with this automatic machine is resolved into M1 and two quality of M2, use the mode of the time difference that spaces out to stagger M1 and M2 at the volley, make M2 in the recoil motion not clash into the casing tailstock and directly bump against, advance the effect that speed reduces the shooting frequency again thereby play to alleviate the impact that the automatic machine recoil puts in place and delay automatic machine with the multiple M1 that advances in the motion.
Technical scheme of the present invention can realize by following concrete measure: used machine frame is divided into loss of weight machine frame 1 and the piston element two parts that have reliable connection therebetween usually, its piston element comprises piston 8 and is limited in deceleration 7 of its inside and the sub-spring 6 that slows down, under spring force and effect of inertia, the son that slows down have piston 8 axially on one section reciprocating space.Described M2 comprises the part of the quality of the son 7 that slows down and sub-spring 6 quality of slowing down, and M1 comprises and removes remaining part quality behind the M2 in the quality of the quality of loss of weight machine frame 1 and gunlock 9 and piston element.When the automatic machine recoil began, M1 and M2 be simultaneously with identical speed recoil, and when the M1 recoil put bump casing tailstock in place, M2 had still just begun the compression sub-spring 6 that slows down in the way, recoil.Behind the M1 bump casing tailstock, knock-on is also answered forward under the effect of kicker power, when its answer forward into a bit of apart from the time, just bump against with the M2 that continues the recoil because of effect of inertia, the collision of M1 and M2 has reduced the momentum of the multiple middle M1 of advancing, therefore automatic machine has been reduced and advance speed again, played the effect that reduces the shooting frequency.Because of the kinetic energy of M2 no longer affacts on the casing tailstock, also just played simultaneously and subtracted the effect of hitting buffering automatically.
Two, hit the frequency reducing performance for further improving to subtract, also can be simultaneously with the method that changes the piston rod length of fit with increase or dwindle air guide chamber original volume, thereby the speed when regulating piston begins the recoil.
For realizing this technical scheme, this machine frame device can adopt following measure: promptly establish between loss of weight machine frame 1 and piston element and regulate the location link, make and have more than one axial location relation between its two, length of fit with this regulating piston 8, it is the amount doesn't matter to make piston crown enter the air guide chamber, just regulates the size of air guide chamber original volume.When the length of fit of piston 8 was turned down, air guide chamber original volume increased, and the maximum pressure in the air chamber is reduced, and the acceleration of piston 8 is little; The length of fit of piston 8 is transferred when big, and air guide chamber original volume reduces, and the maximum pressure in the air chamber is increased, and makes the acceleration of piston 8 become big.This kind adjusting is carried out as required by shooter.
