[0001] Divisional application statement

[0002] This application is a divisional application of the Chinese invention patent application with the invention name “A high-sealing rotary pressure ring assembly” and application number 202110270632.X filed on February 13, 2020. Technical Field

[0004] Impact testing is generally a test method to determine the safety, reliability and effectiveness of military and civilian equipment when subjected to external impact or action. The impact test bench is mainly used for mechanical environmental testing of products. It can simulate actual impact pulses and impact energy, and simulate non-repetitive impacts that products are expected to suffer during use, loading and unloading, and transportation, so as to determine the product's adaptability to various impact environments.

[0005] At present, most impact test equipment is implemented by free-fall impact testers, which are driven by gravity. However, for impact tests of some specimens, horizontal impact must be used. Among them, the high-frequency vibration control mechanism that generates impact force plays a major role. The current horizontal impact test bench uses the deformation energy of the elastic rope as the power to generate the required initial impact velocity. Because it relies on the deformation energy of the elastic rope to accumulate energy, as the number of uses increases, the elastic rope gradually wears out, and its elastic coefficient decreases accordingly. When it reaches a certain level, it needs to be replaced, and the maintenance cost is high. Summary of the invention

[0006] The purpose of the present invention is to provide a high-frequency vibration control mechanism to solve the problem that when the current horizontal impact test bench uses the deformation energy of an elastic rope as power to generate the required initial impact velocity, the elastic rope gradually wears out as the number of uses increases, and its elastic coefficient decreases accordingly. When it reaches a certain level, it needs to be replaced, resulting in high maintenance costs.

[0007] To achieve the above object, the present invention provides the following technical solution: a high-frequency vibration control mechanism, comprising:

[0008] A support, on which a fixed intake and exhaust distribution wheel is fixedly mounted;

[0009] A pulley, the pulley is arranged inside the support, the two sides of the pulley are connected with a rotating rod, and the tail end of the rotating rod is fixedly connected with a rotating intake and exhaust distribution wheel;

[0010] The rotating inlet and exhaust distribution wheel is arranged opposite to the fixed inlet and exhaust distribution wheel, and 4 groups of rotating inlet and exhaust distribution wheel inlet and exhaust ports are evenly arranged on the rotating inlet and exhaust distribution wheel, and 4 groups of fixed inlet and exhaust distribution wheel inlet ports and fixed inlet and exhaust distribution wheel exhaust ports are respectively and spaced apart on the fixed inlet and exhaust distribution wheel; when the rotating inlet and exhaust distribution wheels at both ends of the rotating rod are driven by the pulley to rotate, the inlet and exhaust ports of the rotating inlet and exhaust distribution wheel can be matched and connected with the inlet ports of the fixed inlet and exhaust distribution wheel, and then the rotating inlet and exhaust distribution wheel is rotated 45°, so that the inlet and exhaust ports of the rotating inlet and exhaust distribution wheel can be connected with the exhaust ports of the fixed inlet and exhaust distribution wheel.

[0011] Preferably, the rotating intake and exhaust distribution wheel and the fixed intake and exhaust distribution wheel are sealed and abutted against each other, so that the rotating intake and exhaust distribution wheel remains sealed during the rotational movement.

[0012] Further preferably, a fixed mounting block is provided on the outer side of the rotating intake and exhaust distribution wheel, and a pressure ring is provided between the fixed mounting block and the rotating intake and exhaust distribution wheel.

[0013] Further preferably, an air intake channel connected to the rotating air intake and exhaust distribution wheel is provided in the fixed mounting block, and the pressure ring is connected to the air intake channel. When the high-pressure gas passes through the air intake channel to press the rotating air intake and exhaust distribution wheel, the rotating air intake and exhaust distribution wheel can be pressed against the fixed air intake and exhaust distribution wheel to achieve a sealed abutment connection.

[0014] Preferably, the fixed intake and exhaust distribution wheel is located between the rotating intake and exhaust distribution wheel and the pulley.

[0015] The present invention provides a high-frequency vibration control mechanism, which has the following beneficial effects:

[0016] By arranging the rotating intake and exhaust distribution wheel and the fixed intake and exhaust distribution wheel opposite to each other, 4 groups of rotating intake and exhaust distribution wheel intake and exhaust ports are evenly opened on the rotating intake and exhaust distribution wheel, and 4 groups of fixed intake and exhaust distribution wheel intake and exhaust ports and fixed intake and exhaust distribution wheel exhaust ports are respectively and spaced apart on the fixed intake and exhaust distribution wheel; when the rotating intake and exhaust distribution wheels at both ends of the rotating rod are driven by the pulley to rotate, the rotating intake and exhaust distribution wheel intake and exhaust ports can be matched and connected with the fixed intake and exhaust distribution wheel intake ports, and then the rotating intake and exhaust distribution wheel is rotated 45 degrees, so that the rotating intake and exhaust distribution wheel intake and exhaust ports can be connected with the fixed intake and exhaust distribution wheel exhaust ports, thereby realizing high-frequency vibration control of the cylinder, with good durability and low maintenance cost.
