Description

Technical Field

[0001] The invention belongs to the technical field of conventional weapons, and in particular relates to a novel mounting device for improving the shooting accuracy of a certain type of heavy machine gun. Background Art

[0002] The combatants manually operate the machine gun on the top of the vehicle (usually an armored vehicle), and the operator's body (above the chest) is exposed to the vehicle for a long time, making it easy to be attacked, resulting in casualties and high safety risks;

[0003] The recoil of a certain type of machine gun is large, which causes a great impact on the shooting device of the fixed machine gun and generates vibration, resulting in an increase in the jump amplitude of the machine gun muzzle, thereby reducing the shooting accuracy;

[0004] The sliding body of the fixed machine gun and the sliding pair of the bracket adopt a surface contact with a large gap. During the reciprocating process of the sliding assembly, the impact force causes uneven contact on the mating surface, and the large gap causes the muzzle to jump up and down, affecting the shooting accuracy;

[0005] The quick installation of common components requires many types of tools, many steps, a long time, and low efficiency;

[0006] The buffer structure layout does not match the recoil force, and cannot effectively offset or consume the kinetic energy of recoil, which easily causes vibrations during continuous shooting. It cannot adapt to situations with large temperature changes, and the damping performance varies greatly. The exposed structure and buffer components are prone to rust and dust accumulation, affecting shooting accuracy.

[0007] When shooting at an elevated angle, the shell hits the inner frame wall of the bracket and the slide body when it is unshelled, and then rebounds to the U-shaped upper surface of the upper frame at the bottom (the rear slope is 35° to 60° to the horizontal), and the shell often rebounds into the shell ejection port.

[0020] The beneficial effects of the present invention are:

[0021] (1) As the main part of the vehicle-mounted weapon station, the overall layout design is optimized, the modular design is compact, and a variety of structures are designed to improve shooting accuracy. Multiple components can be quickly disassembled and installed, and installation and maintenance are simple. The device has a remote control function, and the operator can control the machine gun in the vehicle body. It realizes manual-automatic first-shot loading and manual-automatic integrated electric firing, and realizes single-shot and continuous shooting and control. Through reasonable design layout and structural innovation of each component, a new type of mounting device that combines electromechanical and control, has a high degree of automation, high shooting accuracy, and high reliability is realized under limited space conditions;

[0022] (2) From the design point of view, the present invention firstly reasonably arranges the buffer, selects a structural form in which the axis of the buffer is coplanar with the direction of the recoil force generated by the bullet shooting from the barrel, forms an effect of highly consistent recoil and buffer force, realizes the offset and balance of recoil and buffer force, avoids the bending moment caused by the impact of recoil, and at the same time, arranges the two buffers on both sides of the machine gun, realizes the limited structural space, reduces the load of a single buffer, enhances the stability of the buffer force, and makes the shooting process more stable;

[0023] (3) The design layout of the buffers on both sides of the machine gun is adopted, which is symmetrically distributed on the left and right sides to balance the recoil force, effectively reduce the impact, and improve the stability and accuracy of shooting; the sliding body of the fixed machine gun and the sliding pair of the bracket adopt a surface contact with a large gap. During the reciprocating process of the sliding assembly, the impact force causes uneven contact of the mating surface, and the large gap causes the muzzle to jump up and down, affecting the shooting accuracy; structurally, by installing the sliding guide rails on four positioning surfaces on the same plane on the upper surface of the bracket, a four-point split guide rail and slide seat combination structure of the slide seat assembly is formed; it has the advantages of large front and rear span, small size, high rigidity, good stability, and low friction; the sliding guide rail and the precision slide seat are matched, positioned and tightened, and during the shooting process, the gap between the slide seat assembly and the bracket is effectively eliminated, the rolling friction is small, and the front and rear linear motion accuracy of the machine gun is improved, especially the muzzle jump is effectively reduced, and the shooting accuracy is improved;

[0024] (4) By setting up quick-disassembly and quick-assembly structures for the three devices, the time for installation, maintenance and replacement is shortened, and the reliability, stability and convenience of installation and disassembly are improved, which is of great significance for the installation and maintenance of the mount device, especially maintenance on the battlefield;

[0025] (5) The buffer is designed as a closed split structure, and the internal structure adopts a structure in which the buffer elements can be configured and combined according to the buffering requirements. The length of the inner cavity can be adjusted to achieve the purpose of adjusting the preload force; the inner hole of the end face cooperates with the locking hoop journal of the machine gun. When the impact recoil occurs, the core shaft rod is pushed by the axis of the recoil force, which drives the compression and extension of the elastic element inside the buffer to achieve the buffering effect; through the adjustment of multiple elastic elements and internal space dimensions, different buffering mechanical properties of the buffer are achieved, which has stronger adaptability and versatility;

[0026] (6) The manufacturing process should meet the high design precision of the device and provide a good structural platform and foundation for shooting accuracy;

[0027] (7) By having a tough inclined surface, the direction of the cartridge case being discharged is changed to avoid rebounding in the direction of the cartridge case outlet; a rebound shielding effect is generated to prevent the cartridge case from rebounding;

[0028] (8) The overall design of the progressive belt guide chamber is a special-shaped structure that is open at both ends and wrapped all around. Through sheet metal, welding, and surface treatment, it forms an integrated structure that is easy to install and has a stable connection. BRIEF DESCRIPTION OF THE DRAWINGS
