Description

Technical Field

[0001] This invention relates to the field of buffer technology, and in particular to a recoil buffer device for continuous firing. Background Technology

[0002] With the development of weapons, in order to reduce recoil, most weapons, whether large-caliber artillery, aircraft cannons, small-caliber automatic cannons, or firearms such as 12.7mm machine guns, adopt buffer devices.

[0003] Initially, the cushioning device used a pure spring structure, but due to the drawbacks of low energy consumption and poor cushioning effect, a hydraulic cushioning device was later adopted. The hydraulic cushioning device mainly uses sealed hydraulic oil to buffer the recoil force.

[0004] The applicant has discovered at least the following technical problems with the existing technology: Existing hydraulic buffer devices have complex structures, high costs, and their performance is easily affected by temperature. More importantly, the internal structure of hydraulic buffer devices is filled with oil, requiring extremely high sealing performance. If the seals are damaged or improperly installed, oil leakage may occur. Oil leakage not only affects the normal operation of the buffer device but may also pollute the surrounding environment and increase the workload of cleaning and maintenance. Furthermore, existing hydraulic buffer devices lack sufficient rigidity, resulting in significant recoil displacement after buffering. Summary of the Invention

[0005] The purpose of this invention is to provide a recoil buffering device for continuous firing, thereby solving the technical problems of poor buffering performance in existing hydraulic buffering devices due to the significant influence of temperature. The preferred technical solutions among the various technical solutions provided by this invention and the resulting numerous technical effects are detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The continuous firing recoil buffer device provided by the present invention includes a connector, a guide rod, a cylinder assembly, a damping cylinder located within the cylinder assembly, and an elastic support member, wherein:

[0008] The connector is fixedly connected to the guide rod, and the connector is used to fixally connect to the device to be buffered; the guide rod passes through the cylinder assembly, and at least a portion of the guide rod is located inside the cylinder assembly, and the damping cylinder is fixedly sleeved on the guide rod;

[0009] The two elastic supports are located at opposite ends of the damping cylinder and are fixedly connected to the damping cylinder and the cylinder assembly. The cylinder assembly is sealed with damping grease, which encapsulates the damping cylinder and the elastic supports.

[0010] Preferably, the damping cylinder has a groove structure on its side wall, and the groove structure extends through both ends of the damping cylinder.

[0011] Preferably, the groove structure is a spiral groove, which is arranged around the axis of the damping cylinder and extends to the end face of the damping cylinder.

[0012] Preferably, the outer diameter of the damping cylinder is larger than the inner diameter of the cylinder assembly, so that the damping cylinder is squeezed and assembled inside the cylinder assembly.

[0013] Preferably, the damping cylinder is fixed with pads at both ends. The pads are used to prevent shear deformation caused by the axial movement of the damping cylinder. The pads are fixedly connected to the elastic support.

[0014] Preferably, the elastic support is sleeved on the guide rod, and the elastic support includes a disc spring.

[0015] Preferably, the cylindrical assembly includes an outer sleeve and a support, wherein:

[0016] The bracket is fixedly connected to the outer sleeve and forms a sealed space. The guide rod passes through the sealed space. The elastic support and damping cylinder are located in the sealed space, and the damping grease is filled in the sealed space.

[0017] The bracket is provided with a guide groove, which is arranged along the axial direction of the outer sleeve. The connection part between the joint and the guide rod is located in the guide groove and is arranged to reciprocate along the guide groove.

[0018] Preferably, an inner core is fixed inside the cylindrical assembly, the inner core is located at one end of the sealed space facing the joint, and a sealing ring is fixed outside the inner core, thereby sealing the damping grease in the sealed space;

[0019] The guide rod passes through the inner core, and axial displacement can occur between the guide rod and the inner core.

[0020] Preferably, a guide ring and a dust plug are fixed inside the end of the cylindrical assembly away from the joint. The dust plug is located outside the guide ring. The guide rod passes through the guide ring and the dust plug and can undergo relative axial displacement with the guide ring and the dust plug.

[0021] Preferably, the continuous firing recoil buffer device further includes a fixing frame, which is fixedly connected to the connector and is used to support and fix the device to be buffered.

[0022] The fixing frame includes a U-shaped frame, and the opposite sides of the U-shaped frame are fixedly connected to the corresponding joint portion.

[0023] The continuous firing recoil buffer device provided by this invention has the following advantages compared with the prior art: the connector is fixedly connected to the machine gun. When the buffer device is working, the impact force of the machine gun is transmitted to the guide rod through the connector. The guide rod and the damping cylinder move synchronously along the axial direction of the cylinder assembly, stretching the elastic support. After recoil, the guide rod and the damping cylinder return to their original positions by the elastic support. Since the damping grease wraps around the damping cylinder and the elastic support, the damping grease moves when the damping cylinder moves. The damping grease can effectively reduce the impact and vibration in the mechanical system, improve the stability and service life of the equipment, and the damping grease has excellent anti-oxidation properties, which can ensure long-term stable lubrication effect. It is suitable for various extreme temperature environments. Whether at low or high temperatures, it can play an excellent lubrication role, thereby realizing the buffer function and reducing recoil energy.

[0024] Furthermore, the continuous firing recoil buffer device of this structure ensures rigidity through elastic support components and buffers machine gun recoil through the cooperation structure of damping cylinder, damping grease and elastic support components. This device has sufficient rigidity and has a good suppressive effect on excessive displacement caused by superposition, which can significantly reduce the recoil of the weapon and is beneficial to improving weapon mobility and shooting accuracy.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0036] In the description of this invention, it should be understood that the terms "center," "length," "width," "height," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and "side," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0037] This invention provides a recoil buffer device for continuous firing. The device has sufficient rigidity and can effectively suppress excessive displacement caused by superposition, thereby significantly reducing the recoil of the weapon.

[0038] The following is combined with Figures 1-7 The technical solution provided by this invention will be described in more detail below.

[0039] like Figures 1-4As shown, the continuous firing recoil buffer device provided by the present invention includes a connector 1, a guide rod 2, a cylinder assembly, a damping cylinder 3 located inside the cylinder assembly, and an elastic support 4, wherein: the connector 1 is fixedly connected to the guide rod 2, and the connector 1 is used to fixally connect to the device to be buffered; the guide rod 2 passes through the cylinder assembly, and at least a portion of the guide rod 2 is located inside the cylinder assembly, and the damping cylinder 3 is fixedly sleeved on the guide rod 2; two elastic supports 4 are respectively located at opposite ends of the damping cylinder 3, and are fixedly connected to the damping cylinder 3 and the cylinder assembly; the cylinder assembly is sealed and filled with damping grease 6, and the damping grease 6 wraps around the damping cylinder 3 and the elastic support 4.

[0040] The connector 1 serves to transmit vibration and is fixedly connected to the guide rod 2. The two can be an integral structure or a snap-fit ​​method. The vibration of the recoil force is transmitted to the connector 1. The connector 1, the guide rod 2, and the damping cylinder 3 fixed on the guide rod 2 move together along the axial direction of the cylinder assembly, pushing the elastic support 4 and the damping grease 6. The elastic support 4 mainly provides the stiffness of the buffer structure and the restoring force of the damping cylinder 3.

[0041] The damping cylinder 3 can be made of materials with elastic buffering force, such as rubber, thereby improving the buffering effect.

[0042] In this embodiment, the continuous firing recoil buffer device has a connector 1 fixedly connected to the machine gun. When the buffer device is working, the impact force of the machine gun is transmitted to the guide rod 2 through the connector 1. The guide rod 2 and the damping cylinder 3 move synchronously along the axial direction of the cylinder assembly, stretching the elastic support 4. After recoil, the guide rod 2 and the damping cylinder 3 return to their original positions by the elastic support 4. Since the damping grease 6 wraps around the damping cylinder 3 and the elastic support 4, the damping grease 6 moves when the damping cylinder 3 moves. The damping grease 6 can effectively reduce the impact and vibration in the mechanical system, improve the stability and service life of the equipment, and the damping grease 6 has excellent anti-oxidation properties, which can ensure long-term stable lubrication effect. It is suitable for various extreme temperature environments. Whether at low or high temperatures, it can play an excellent lubrication role, thereby realizing the buffer function and reducing recoil energy.

[0043] Furthermore, the continuous firing recoil buffer device of this structure ensures rigidity through the elastic support 4, and buffers the machine gun recoil through the cooperation structure of the damping cylinder 3, damping grease 6 and the elastic support 4. This device has sufficient rigidity and has a good suppressive effect on excessive displacement caused by superposition, which can significantly reduce the recoil of the weapon and is beneficial to improving the weapon's mobility and shooting accuracy.

[0044] Based on the requirements for the buffer and combined with the common buffer structure principle, this buffer device is suitable for 12.7mm machine guns. The buffer device adopts the working principle of spring damping cylinder 3. The elastic support 4 (spring) is used to absorb recoil energy and store recoil energy. It can obtain a large pre-pressure with a small compression, which makes it easier to smooth the recoil pulse and reduce the recoil peak.

[0045] Regarding the statement that "the device has sufficient stiffness and effectively suppresses excessive displacement caused by superposition," specific experimental data will be used to illustrate this point later.

[0046] As an alternative implementation, see [link to implementation details]. Figure 2 and Figure 3 As shown, a groove structure is provided on the side wall of the damping cylinder 3, and the groove structure extends through both ends of the damping cylinder 3. For details, see [link to details]. Figure 3 As shown, the groove structure is a spiral groove 301, which is arranged around the axis of the damping cylinder 3 and extends to the end face of the damping cylinder 3.

[0047] Because the spiral groove 301 extends to the end face of the damping cylinder 3, the damping grease 6 inside the cylinder assembly can enter the spiral groove 301. The spiral groove 301 connects the spaces on both sides of the damping cylinder 3, meaning that the damping grease 6 on both sides of the damping cylinder 3 is connected by the spiral groove 301. When the damping cylinder 3 moves axially along the cylinder assembly like a "piston," the damping grease 6 inside the cylinder assembly prevents air from entering the cylinder assembly and prevents the damping cylinder 3 from compressing air, thus preventing a pressure difference between the two sides of the damping cylinder 3.

[0048] The aforementioned spiral groove 301 structure, when the damping cylinder 3 moves axially along the cylinder assembly like a "piston," can drive some of the damping grease 6 to flow, thereby improving the buffering effect. Damping grease 6 is a high-viscosity lubricant that can meet the precise requirements of various mechanical equipment for rotation or sliding motion. It can effectively reduce shocks and vibrations in mechanical systems, improving equipment stability and service life. Damping grease 6 has excellent anti-oxidation properties, ensuring long-term stable lubrication. Damping grease 6 is suitable for various extreme temperature environments, providing excellent lubrication regardless of whether it is low or high temperature.

[0049] As an alternative implementation, see [link to implementation details]. Figure 1 and Figure 2 As shown, the cylindrical assembly includes an outer sleeve and a bracket 52, wherein: the bracket 52 is fixedly connected to the outer sleeve and encloses a sealed space, the guide rod 2 passes through the sealed space, the elastic support 4 and the damping cylinder 3 are located in the sealed space, and the damping grease 6 is filled in the sealed space; a guide groove is provided inside the bracket 52, the guide groove is arranged along the axial direction of the outer sleeve, the connection part of the joint 1 and the guide rod 2 is located in the guide groove, and is arranged to reciprocate along the guide groove.

[0050] The bracket 52 serves to fix the outer sleeve. One end of the outer sleeve is fixedly connected to the bracket 52 and seals the aforementioned sealing space to ensure sealing performance.

[0051] As an alternative implementation, see [link to implementation details]. Figure 2 As shown, the outer diameter of the damping cylinder 3 is larger than the inner diameter of the cylinder assembly, thereby causing the damping cylinder 3 to be squeezed and assembled inside the cylinder assembly.

[0052] The damping cylinder 3 is located between two elastic supports 4, maintaining its ability to move freely along the axial direction of the cylinder assembly. The outer diameter of the vulcanized damping cylinder 3 is slightly larger than the inner diameter of the outer sleeve, so that when the damping cylinder 3 is pressed into the outer sleeve, it deforms radially and has a certain amount of compression, i.e., initial surface pressure, on the contact surface. During operation, the damping cylinder 3 moves axially.

[0053] As an optional implementation, such as Figure 2 and Figure 4 As shown, the damping cylinder 3 has pads 12 fixed at both ends. The pads 12 are used to prevent shear deformation caused by the axial movement of the damping cylinder 3. The pads 12 are fixedly connected to the elastic support 4.

[0054] To prevent large shear deformation of the damping cylinder 3 during axial movement, see [link to relevant documentation]. Figure 2 As shown, a pad 12 is used to constrain it, so that the damping cylinder 3 can only move relative to the cylinder assembly along the axial direction.

[0055] As an alternative implementation, see [link to implementation details]. Figure 2 As shown, the elastic support 4 is sleeved on the guide rod 2, and the elastic support 4 includes a disc spring.

[0056] Using a disc spring not only provides high stiffness and a small size, but also helps to dissipate some of the recoil energy.

[0057] As an alternative implementation, see [link to implementation details]. Figure 2 As shown, an inner core 7 is fixed inside the cylinder assembly. Specifically, the inner core 7 is located at one end of the outer cylinder 51 and at the end of the sealed space facing the joint 1. A sealing ring 8 is fixed outside the inner core 7 to seal the damping grease 6 in the sealed space. The guide rod 2 passes through the inner core 7, and axial displacement can occur between the guide rod 2 and the inner core 7.

[0058] The mating structure of the inner core 7 and the sealing ring 8 can seal the outer cylinder 51 from one end, thereby blocking the damping grease 6 and preventing the damping grease 6 from overflowing.

[0059] As an alternative implementation, see [link to implementation details]. Figure 2As shown, a guide ring 10 and a dust plug 11 are fixed inside one end of the cylinder assembly away from the joint 1. The dust plug 11 is located outside the guide ring 10. The guide rod 2 passes through the guide ring 10 and the dust plug 11 and can undergo relative axial displacement with the guide ring 10 and the dust plug 11.

[0060] The mating structure of the guide ring 10 and the dust plug 11 can seal the outer cylinder 51 from the other end, thereby blocking the damping grease 6 and preventing the damping grease 6 from overflowing. Furthermore, the guide ring 10 does not obstruct the axial movement of the guide rod 2.

[0061] As an alternative implementation, see [link to implementation details]. Figure 1 As shown, the recoil buffer device after continuous firing also includes a fixing frame 9, which is fixedly connected to the connector 1. The fixing frame 9 is used to support and fix the device to be buffered. The fixing frame 9 includes a U-shaped frame, and the opposite sides of the U-shaped frame are fixedly connected to the corresponding connector 1.

[0062] Specifically, the U-shaped frame can be equipped with structures such as clips. When the machine gun recoil is located inside the U-shaped frame, the clips can fix the machine gun recoil, or conventional fixing methods can be used to fix the machine gun recoil, which will not be elaborated on further.

[0063] The continuous firing recoil buffer device in this embodiment is first analyzed through simulation: see [link to simulation analysis]. Figure 5 As shown, the firing parameters of the machine gun, such as rate of fire, recoil, torque, pressure, center of gravity, and centrifugal force, are summarized, and a theoretical model of the buffer is established using Simcenter, such as... Figure 5 As shown, parameters such as stiffness, damping, and displacement are then adjusted to achieve the desired buffering effect, thus completing the theoretical model.

[0064] Figure 5 In the process of establishing the theoretical model of the buffer, the highest input radio frequency is 600 RF / min and the maximum recoil force requirement is 8000N. An equivalent external force is established to simulate the equivalent stiffness, damping, and displacement of the output.

[0065] For machine guns, the extremely high firing rate also increases the total impulse experienced by the mount per unit time, intensifying vibration and severely affecting firing accuracy. To ensure and improve the firing accuracy of weapon systems, taking effective measures to reduce recoil is crucial. Using a small, high-efficiency buffer can significantly reduce the peak recoil, improving firing accuracy without compromising weapon mobility, making it an effective and feasible method.

[0066] Due to its high radio frequency, the time it takes for a machine gun to fire one round (i.e., one automatic cycle) is very short. The time for the gun to complete one recoil and return cycle under the action of the buffer is also very short (approximately 6ms). This can lead to the weapon firing multiple rounds during a single recoil, resulting in excessive recoil displacement and limited recoil reduction. Therefore, while significantly reducing the peak recoil force, the buffer device should avoid excessive recoil displacement. The main design requirements for the buffer are: compact structure, small size, and light weight; high energy absorption, low heat generation, rapid heat dissipation, and low temperature rise; the maximum recoil displacement should be as small as possible, the recoil reduction should be significant, and the buffer should have good operational stability and be less susceptible to external interference.

[0067] The structure of the recoil buffer device after continuous firing in this embodiment meets the above requirements.

[0068] The following explanation, based on specific experimental data, clarifies that "the device possesses sufficient rigidity and effectively suppresses excessive displacement caused by superposition."

[0069] 1. Regarding static stiffness and dynamic stiffness.

[0070] See Table 1 below:

[0071] Table 1. Test data of the recoil buffer device after continuous firing.

[0072] Frequency (Hz) Week Load amplitude (N) Displacement amplitude (mm) Dynamic stiffness (N / mm) Loss angle (radians) Loss tangent Damping coefficient Transmission coefficient Prequency Circles F_DYN S_DYN K_DYN ANGLe TAN C_FOU TRANSN 10 57 245.225 0.302 811.882 0.519 0.572 7.388 1.859

[0073] As can be seen, the dynamic stiffness of the recoil buffer device after continuous firing meets the requirements.

[0074] See Figure 6 As shown in the figure, the slope of the curve represents the static stiffness value, which is approximately 600, meeting the requirements.

[0075] The static-dynamic stiffness ratio of the continuous firing recoil buffer device in this embodiment is close to 1.8. Through the combination of materials and damping grease 6, it is beneficial to resist energy loss caused by wear.

[0076] 2. This buffer device has a good suppressive effect on excessive displacement caused by superposition.

[0077] See Figure 7 As shown, the recoil characteristics at different rates of fire are as follows: when the machine gun's rate of fire is 600 rounds / min and the recoil force is 2000N, the maximum recoil displacement is 4.8 (vertical axis in the figure). Therefore, after the buffering effect of this buffer device, the machine gun's recoil displacement is relatively small. This type of buffer effectively suppresses excessive early-field displacement due to superposition, significantly reducing weapon recoil and greatly improving weapon mobility and firing accuracy.

[0078] This buffer device, by adjusting the stiffness and preload of the elastic support 4, generates a combined force of frictional damping and buffer spring force that effectively dissipates almost all of the kinetic energy of the gun barrel. Therefore, the gun barrel no longer experiences the repeated, damped oscillating motions of recoil, return, re-recoil, and re-return that occur with traditional buffers, thus ensuring that recoil force does not accumulate during machine gun firing. This structural working principle guarantees the machine gun's firing stability and service life.

[0079] 3. See Figure 8 As shown in the figure, the buffer device has a good buffering effect. It can be seen from the figure that by using the buffer device, the recoil force is reduced from 1000N to below 2000N, which is 80% less.
