Description

Technical Field

[0001] The invention belongs to the field of automatic weapon simulation test, and in particular relates to a rotary locking mechanism simulation test device. Background Art

[0002] Automatic weapons require a closed chamber and a secure hold on the cartridge case during firing to prevent it from breaking and preventing the release of gunpowder gases. After firing, the cartridge case must be promptly withdrawn to ensure the next round enters the chamber, ensuring effective and safe firing. The locking mechanism in automatic weapons fulfills this function. The reliability of its operation significantly impacts the reliability and safety of the entire automatic weapon system, making it a crucial factor to consider during the design process.

[0003] Locking mechanisms operate in two main categories: inertial locking and rigid locking. Among rigid locking mechanisms, rotary locking mechanisms are widely used in gas-operated and barrel-recoil automatic weapons due to their uniform force distribution, smooth operation, flexibility, reliability, and strong environmental adaptability. To ensure a smooth and stable opening and closing process, a guiding helical surface is essential. The rationality of the helical surface design directly determines the stability and reliability of the rotary locking mechanism. Relying on design experience and trial and error through repeated live-fire exercises is the current common approach to rotary locking mechanism design. However, this method is costly and inefficient, and test results are easily affected by ammunition variations and test conditions. Furthermore, because rotary locking mechanisms are often located within the automatic weapon's automaton, their motion parameters are often difficult to observe and measure, further complicating the design of rotary locking mechanisms. Summary of the Invention

[0004] The purpose of the present invention is to provide a rotary locking mechanism simulation test device, which does not require live ammunition during the test process, has key components placed outside and structural parameters that are easy to adjust, and is convenient for monitoring and recording the motion characteristics of the rotary locking mechanism, thereby solving the shortcomings of traditional methods such as poor economic benefits, low test efficiency, inability to adjust component structural parameters, and difficulty in observing the movement process.

[0023] Combine Figure 1A rotary locking mechanism simulation test device includes a base 1, on which are mounted a first sensor 2, a sensor bracket 3, and a locking mechanism assembly 4. The sensor bracket 3 and the locking mechanism assembly are fixedly mounted on the base 1. The first sensor 2 is fixedly connected to the sensor bracket 3 and connected to the locking mechanism assembly 4 via a coupling.

The first bracket 402 and the second bracket 412 are respectively fixed to the two ends of the guide rail seat 407; the guide rail seat 407 is fixed on the base 1, the first bearing seat 401 and the second bearing seat 411 are respectively fixed to the first bracket 402 and the second bracket 412, and bearings are provided in the first bearing seat 401 and the second bearing seat 411 for supporting the machine head 405; the first guide rail piece 403 and the second guide rail piece 406 Symmetrically arranged on both sides of the top of the guide rail seat 407, the guide rail gap can be adjusted by changing the thickness of the first guide rail piece 403 and the second guide rail piece 406, thereby realizing the simulation of the opening and closing locking process under different guide rail gaps; the machine head 405 is arranged between the first guide rail piece 403 and the second guide rail piece 406, and one end is arranged at the second bearing seat 411, and the other end passes through the first bearing seat 401 and is connected to the first sensor 2 through a coupling, and a guide protrusion 40501 is provided on the machine head 405; the machine body 408 is clamped on the first guide rail piece 403 and the second guide rail piece 406, and is coaxial with the axis of the machine head 405, and can move forward and backward along the axis direction of the machine head 405, and a spiral groove 40801 is provided on the machine body 408; the guide protrusion of the machine head 405 40501 is arranged at the spiral groove 40801 of the body 408, and can rotate driven by the spiral groove 40801. The head is detachable, and the simulation of the opening and closing process under different spiral structures can be achieved by adjusting the width and spiral parameters of the spiral groove 40801; the recoil spring 404 is coaxial with the axis of the head 405 and is placed between the body 408 and the first bracket 402, for supplying energy to the recoil process; the push rod 410 is fixedly installed on the body 408, for receiving external force and driving the entire simulation device to move; the second sensor 409 is arranged on the body 408 and moves with the body 408.

[0025] The working process of the rotary locking mechanism simulation test device of the present invention is as follows:

[0026] Under the action of external force, the push rod 410 of the locking mechanism assembly 4 drives the body 408 to move backward and compress the return spring 404. The spiral groove 40801 of the body 408 guides the guide protrusion 40501 of the machine head 405 and drives the machine head 405 to rotate, so as to simulate the unlocking rotation process; due to the energy storage effect of the return spring 404, the speed of the body 408 gradually decreases and returns to its original position under the action of the return spring 404, while driving the machine head 405 to rotate in the opposite direction, completing the simulation of the locking rotation process; during the entire action process, the first sensor 2 monitors and records the rotational motion parameters of the machine head 405, and the second sensor 409 monitors and records the translational motion parameters of the body 408; at the same time, by adjusting the structural parameters of the first guide rail piece 403, the second guide rail piece 406, and the spiral groove 40801 of the body 408, the simulation of the unlocking and closing process under different structural parameter conditions can be completed.

[0027] The present invention provides a firearm automatic mechanism simulation test device, wherein the test process does not require live ammunition, key components are located externally, and structural parameters are easily adjustable, thereby facilitating monitoring and recording of the motion characteristics of a rotary locking mechanism.
