[0002] The vibration test bench is mainly used to simulate the working state of the product in various environments (such as vibration, impact, collision, etc.) to detect whether its performance and parameters meet the requirements and evaluate its adaptability under various environmental conditions. The equipment is widely used in electronics, machinery, automobiles, aerospace, weapons, medical equipment and other industries. The vibration test bench is mainly composed of measurement and control system, vibration table, vibrator, sensor and other parts. The measurement and control system is responsible for data acquisition, processing and control. The vibration table and vibrator constitute the core part of the simulated vibration environment, and the sensor is used to measure the various parameters of the tested product. The fixed structure in the vibration test bench is mainly used to fix the vibration table to ensure that the vibration table can be stably mounted on the vibrator, thus forming a complete vibration test system.

[0028] The setting of the buffer spring 505 can absorb the impact energy during the movement of the vibration platform 3, reduce the impact of vibration on the vibration platform 3 and the equipment, thereby reducing damage to the equipment and errors in the test results. The mounting plate 501 and the base plate 507 serve as the supporting structure of the supporting mechanism 5, providing a stable supporting effect. The base plate 507 is fixed to the working ground area by multiple sets of positioning bolts 508, ensuring the overall stability and supporting strength of the supporting mechanism 5. The coordinated use of the limit nut 503 and the screw rod 504 realizes the adjustment effect of the tightness of the buffer spring 505 in the supporting mechanism 5.

[0029] The docking mechanism 4 includes a docking plate 401, a limit block 402, a docking groove 403, a first limit plate 404, a first limit block 405, a first button 406, a second limit plate 407, a second limit block 408, a second button 409, a docking slot 410 and a driving gas rod 411.

Its telescopic action drives the relative movement of the limit block 402 and the vibration platform 3, thereby realizing the installation and disassembly process of the vibration platform 3. The setting of the docking mechanism 4 can also ensure that the movement process of the vibration platform 3 is fast and smooth, and the noise is reduced. The first button 406, the second button 409 and the driving gas rod 411 are used in conjunction with each other to conveniently control the telescopic action of the driving gas rod 411. The first button 406 is used to trigger the telescopic action of the driving gas rod 411, which is convenient for the operator to control the docking process.

[0031] The working principle of the utility model is as follows: the vibration test bench is additionally provided with a docking mechanism 4 and a supporting mechanism 5, the docking mechanism 4 is a fixed structure connecting the vibrator 2 and the vibration table seat 3, the supporting mechanism 5 is a fixed structure of the entire vibration test bench, the driving gas rod 411 inside the docking mechanism 4 needs to be connected to electricity, when using the vibration test bench, if it is necessary to install or replace the vibration table seat 3, the docking mechanism 4 can be activated, firstly, the vibration table seat 3 is placed on the docking mechanism 4, so that the docking groove 403 wraps the docking plate 4 01 and the limit block 402, and then rotate the vibration platform 3, so that the limit block 402 moves to the upper surface of the first limit plate 404 and the second limit plate 407, and the limit block 402 hits the first button 406 on the first limit block 405 and the second button 409 on the second limit block 408. When the first button 406 and the second button 409 are pressed, the driving gas rod 411 will start automatically, and the push rod of the driving gas rod 411 will be pushed upward, thereby pushing the vibration platform 3, and the limit There is a limiting relationship between the positioning block 402 and the limiting plates (the first limiting plate 404 and the second limiting plate 407), thereby achieving the effect of fixing the vibration platform 3. The difference is that if the vibration platform 3 needs to be removed, it is only necessary to start the driving gas rod 411 again so that the driving gas rod 411 no longer pushes the vibration platform 3. At this time, it is only necessary to rotate the vibration platform 3 to achieve the effect of removing the vibration platform 3; and the supporting mechanism 5 is distributed on the four sides of the vibration test bench to support the vibration test bench as a whole. Before using the supporting mechanism 5, it is necessary to pre-fix the base plate 507 with the help of multiple sets of positioning bolts 508 in the working ground area. During use, the base plate 507 and the multiple sets of positioning bolts 508 provide a stable fixed support effect, which can effectively prevent the overall shaking of the vibration test bench, and the buffer spring 505 provided provides an efficient buffering effect. When the vibration test bench vibrates, the buffer spring 505 will absorb a certain amount of kinetic energy, thereby achieving the effect of buffering vibration and reducing operating noise.
