Description

The invention relates to the design of small arms and cannon weapons and is used to aim a machine gun at a target and give it stability when firing.

When conducting combat operations in an urbanized area, the need arises for the mobile movement of large-caliber fire weapons. Currently, the Russian Army does not have in service a machine gun for the NSV machine gun, which can be mounted on a combat vehicle. To achieve mobility, an urgent task is to develop such means of installing small arms on vehicles that are in service and actively used in the theater of operations. They will increase the firepower of mobile combat groups, increase the maneuverability and mobility of fire units, ensuring high-quality execution of the combat mission. Let's consider analogues of small arms installation means.

A machine gun machine [1] is known, containing a cradle with a butt, a swivel and a tripod base. It is designed to aim the barrel at the target and conduct intense fire at the position. The disadvantages of the device are: the large dimensions of the base structure, which reduce the maneuverability of the weapon and do not allow the installation of a machine gun in a limited space (vehicle). Also, the significant mass of the structure reduces the mobility of the combat crew when performing a fire mission.

A device for an automatic small arms machine [2] is known, containing a base (fixed part) of the machine, a swivel, a cradle, a guidance mechanism, support legs, at least one of which is equipped with an additional axis located next to the axis of rotation of the leg, connected by means of a threaded connection to an additional axis fixed in the base (fixed part) of the machine.

The disadvantage of this machine is the complex device for threaded connection of additional axes of the leg and the stationary part of the machine, which includes a rod with a cylindrical threaded part and a threaded coupling with a handle for its rotation. In addition, the complex design of the device in the presence of gaps in the threaded connection does not ensure fixation of the angular position of the legs of the machine relative to its stationary part, which affects the accuracy of aiming the weapon when firing, worsens the dispersion characteristics and its combat effectiveness.

A machine gun mount is known [3], containing a moving part with a fastening mechanism, an upper part of the frame with a fastening mechanism, a lower part of the frame with elements of its fastening mechanism - lugs with bevels. The upper and lower parts of the frame are made with rows of holes for bolted connections of the frame in positions of different heights.

A disadvantage of the known device is the complexity of the design of the fastening mechanism, which is sensitive to mechanical damage and contamination. Installing a machine gun on a vehicle requires labor-intensive plumbing and installation work, which will take a long amount of time, which is sorely lacking in combat conditions.

The purpose of the invention is to implement a simple, reliable design of the machine with the ability to quickly install a 12.7-mm NSV machine gun on a vehicle, increasing the firepower of mobile groups, the combat potential and efficiency of using the vehicle.

The invention is illustrated by drawings: Fig. 1 - right view of the machine for the 12.7 mm NSV machine gun; Fig.2 - left view of the machine for the 12.7 mm NSV machine gun; Fig.3 - top view of the machine for the 12.7 mm NSV machine gun; Fig.4 - trigger mechanism of the machine for the 12.7 mm NSV machine gun: a - left view; 6 - top view.

To achieve the purpose of the invention, it is necessary to use a machine for a 12.7-mm NSV machine gun (Fig. 1, 2), which consists of: a base 1 intended for mounting the machine and the NSV machine gun on a vehicle; housing 2, designed to connect all the mechanisms of the machine and give direction to the barrel of the NSV machine gun when firing; machine guidance handle 3, loading mechanism guide 4; loading mechanism rods 5; loading mechanism handles 6; handles with release lever 7; fuse 8; cable 11 of the release mechanism; return spring 10 of the loading mechanism; release mechanism 16.

Distinctive features: a body is used, on which there are grooves for installing a machine gun, connected by a hinge to the base, a loading mechanism guide fixed to the body using electric arc welding, having a groove for the loading mechanism rod stroke connected to the loading mechanism handle, on which a return spring is fixed connected to the body, handle with a trigger lever having in the upper part a safety lock for fixing the trigger lever from accidental pressing, the trigger lever in turn is connected to the trigger mechanism by a cable, the trigger mechanism, in which there is a rod for pressing the trigger lever of the machine gun trigger mechanism when the cable is tensioned, fixed to the machine body by axes.

The operating principle of the invention, implemented in the form of a machine for the 12.7-mm NSV machine gun: the developed machine is installed by a team of two people at the mounting location with the vehicle using anchor bolts. Next, the 12.7 mm NSV 9 machine gun is installed in the mounting grooves 20 on the body 2 of the machine. Next, a belt with ammunition is installed, then the soldier uses the handle of the loading mechanism 6 to load the machine gun and, due to the return spring 10, returns to its original position. In this position, the 12.7 mm machine gun is ready for combat. If it is necessary to fire, the soldier aims the barrel with the help of a sighting device at the target using the machine's pointing handles 3 and the handles with the trigger lever 7, then unscrews the fuse 8 counterclockwise, which unlocks the movements of the trigger lever, then when acting on it, the cable 11 is tensioned, which is connected to the axis 15 of the pressing lever 14, which is located under the casing of the trigger mechanism 17 on the pressing rod 18, mounted on the axis 12, to the trigger lever of the trigger mechanism of the NSV machine gun and the shot is fired. The release mechanism 16, in turn, is installed on the body 2 due to the axis 19. When the action on it ceases, the release lever returns to its original position due to the spring 13 installed in the release mechanism 16.

Thus, the invention, implemented in the form of a machine for the 12.7-mm NSV machine gun, has a simple and reliable design that can be installed on a vehicle in order to increase the firepower of mobile groups, combat potential and efficiency of use of the vehicle. The use of the invention will improve the maneuverability of large-caliber machine guns of the NSV type and provide a wide range of combat missions and increase the survivability of fire units in urbanized areas of the theater of operations.
