Description

Gun body buffer structure

This creation is a kind of gun body buffer structure, which provides a body buffer structure using the structure of the retracting and retracting machine.

When the artillery is fired, the warhead is launched forward by the action of the gas, and the rear seat force is generated relative to the bottom of the combustion chamber, so that the structure of the gun body and part of the gun frame are opposite in the opposite direction, which is easy to cause damage to the structure and materials. The hydraulic resistance is generated by the retreating oil, and the retracting spring of the coaxial retracting spring is accumulated. When the retracting speed reaches a reasonable state, the resilience spring is compressed by the spring force to return the gun body to the position before the shooting.

In view of the above-mentioned shortcomings of the prior art, the body buffer structure of the present invention is designed by using the structure of the retracting and retracting machine, and the seat force is more than 70% after the firing of the gun is effectively reduced. The structure design is: a self-made cradle assembly, It is used to support the gun body assembly and the piston assembly, and to withstand the post-shooting force, so that the rear seat direction and the re-entry motion maintain a fixed trajectory, and the inside of the cradle is filled with the oil retreat. After the gun body is fired, the piston is always A hydraulic resistance is generated during the movement, and the valve flow rate is effectively controlled by a self-made valve and the speed of the buffer body is retracted; a self-made piston assembly is a hollow cylinder that is slidable between the gun body and the cradle, and is internally combined. The mortar shell is used to simultaneously rotate the gun body to retreat and re-enter the gun, so that the gun body assembly can keep reciprocating motion with the cradle, and combine a reentrant spring and related retraction on the outside of the piston. The other components of the machine are integrated with the cradle to effectively control the shooting retreat stroke, and the re-entry spring is used to perform the re-entry movement.

This summary and the following detailed description and drawings are for further explanation. The manner, means and effects of this creation to achieve the intended purpose, and other purposes and advantages of this creation will be explained in the following description and illustration.

Figure 1 is a structural diagram of a gun body buffer structure.

Figure 2 is a schematic diagram of the action of the gun body buffer structure.

The embodiments of the present invention are described below by way of specific specific examples, and those skilled in the art can readily appreciate the other advantages and effects of the present invention from the disclosure herein.

Please refer to FIG. 1 and FIG. 2 , a schematic diagram of the buffer structure of the created gun body and a schematic diagram of the operation. As shown in the figure, the gun body buffer structure comprises a body unit 3 , which is a hollow tube body and The gun tail ball assembly; a piston unit 2, the unit is a slidable hollow cylinder between the gun body unit 3 and the cradle unit 1, and the inner combined with the mortar shell, the two are integrated into one; 1. The unit is a welded single component, which can support the body unit 3 assembly and bear the post-shooting seat force, so that the rear seat direction and the re-entry motion of the gun body unit 3 maintain a fixed trajectory, and the two sides of the gun body are combined with the upper frame, which can be adjusted. The firing angle of the gun system and the strength design of the relevant mechanism shall be transmitted to the upper frame by the retracting and retracting mechanism, and the structure of the gun body unit 3 is maintained stable; The unit is in response to the system of oil retreating in the retracting mechanism of the piston unit 2, which is susceptible to the temperature and the thermal expansion and contraction effect, so that the amount of oil withdrawal in the retracting mechanism is changed, which may cause shooting. Dangerous Therefore, the system oil replenishing unit 4 can timely adjust the amount of oil in the retreating and re-entering mechanism, and the operator can indicate the amount of oil through the oil rod of the refueling replenishing unit 4, and timely replenish or judge the retreat. There is no oil leakage in the inlet mechanism; the retracting and retracting mechanism is designed by the concentric liquid spring mechanism. It is expected to reduce the post-shooting force to 30~35% to improve the system shooting stability; The machine mechanism (including the main components such as the retractor, the re-entry device and the buffer) is integrated with the cradle unit 1 to make the system space configuration more streamlined, to meet the space limitation requirements of the vehicle, and to simultaneously drive the gun body during the shooting of the artillery. The retracting and receding movement enables the gun body unit 3 to maintain a reciprocating motion coaxially with the cradle unit 1, and combines a reentry spring and a related retracting and retracting mechanism mechanism on the outside of the piston unit 2, and the other components and the cradle The unit 1 is integrated and locked to effectively control the shooting retreat stroke, and the retracting movement of the gun body unit 3 is performed by the compression recoil spring.

The scope of the technical content of this creation, any person skilled in the art can modify and change the above embodiments without departing from the spirit and scope of this creation. Therefore, the scope of protection of this creation should be as described later. The scope of the patent application is listed.
