Description
[0001] Divisional application statement
[0002] This application is a divisional application of the Chinese invention patent application with the invention name “A high-frequency vibration control mechanism” and application number 202010090828.6 filed on February 13, 2020. Technical Field
[0003] The invention relates to the technical field of impact test equipment, in particular to a high-frequency vibration control mechanism capable of realizing high-frequency and high-speed intake and exhaust. Background Art
[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 (some are equipped with auxiliary force devices). 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, it requires a longer acceleration process, resulting in a longer slideway. As the number of uses increases, the elastic rope gradually wears out, and its elastic coefficient decreases accordingly. It needs to be replaced to a certain extent, and the use and maintenance costs are high. In addition, this kind of high-frequency vibration control mechanism that uses the elastic rope as the main body cannot perform precise and regular movements, resulting in low detection accuracy. If a cylinder is used as a power source, it is difficult to achieve high-frequency and high-speed intake and exhaust, and it cannot meet the requirements of high-frequency vibration under specific conditions. Summary of the invention

[0013] When in use, the rotating intake and exhaust distribution wheel rotates so that the intake and exhaust ports of the rotating intake and exhaust distribution wheel are matched and connected with the intake ports of the fixed intake and exhaust distribution wheel. After the rotating intake and exhaust distribution wheel is rotated to 45°, the intake and exhaust ports of the rotating intake and exhaust distribution wheel are connected with the exhaust ports of the fixed intake and exhaust distribution wheel.
[0014] High-frequency and high-speed intake and exhaust can be achieved through the high-speed rotation of the rotating intake and exhaust distribution wheel.
[0015] Preferably, when the inlet and exhaust port of the rotating inlet and exhaust distribution wheel is matched and connected with the inlet port of the fixed inlet and exhaust distribution wheel, the gas passes through the pressure ring control inlet and then enters the gas channel from the inlet port of the fixed inlet and exhaust distribution wheel and the inlet and exhaust port of the rotating inlet and exhaust distribution wheel.

[0030] An air inlet 4 is provided on one side of the support 3, and an exhaust hole 10 is provided on the other side of the support 3. A gas channel is provided inside the support 3, and the gas entering from the outside is transported through the gas channel; after the inlet and exhaust port 9 of the rotating inlet and exhaust distribution wheel is connected with the exhaust port 13 of the fixed inlet and exhaust distribution wheel, the gas is discharged through the exhaust hole 10, which is convenient for discharging the gas and can be exhausted regularly; the pulley 5 is connected to the transmission pulley through a belt, and the transmission pulley is connected to the driving wheel connected to the output shaft of the external driving motor through a belt, and the motor is used to drive the pulley 5 to rotate so that the rotation speed is uniform; the pressure ring control air inlet 2 is arranged on the support 3, and the gas enters the left cylinder chamber 1 and the right cylinder chamber air inlet and exhaust port 8 through the pressure ring control air inlet 2, the gas channel and the air inlet hole 4, which is convenient for transporting the gas to the air chambers of the left and right cylinders; the rotating rod passes through the fixed inlet and exhaust distribution wheel 11 to ensure that the fixed inlet and exhaust distribution wheel 11 and the rotating inlet and exhaust distribution wheel 6 are sealed and contacted.
