[0028] As Figures 1 to 5 The fastener vibration test device comprises a frame 1, a top plate 2 is installed on the top of the frame 1, a discharge port 3 is formed in the top plate 2, and a plurality of return springs 27 are fixedly installed on one side of the top plate 2; a clamping assembly is installed on one side of the frame 1 close to the top plate 2, and the clamping assembly is used for fixing fasteners; an adjusting assembly is installed on one side of the clamping assembly, and the adjusting assembly is used for adjusting the distance of the clamping assembly to adapt to the size of different fasteners; a vibration assembly is installed on one side of the frame 1 away from the top plate 2, and the vibration assembly is used for providing a vibration source.

[0029] The frame 1 is the main structure of the vibration device, which stably supports the whole vibration test device. When the vibration test starts, the worker first puts the fastener to be tested into the device through the discharge opening 3 on the top plate 2, and then adjusts the spacing between the clamping assemblies according to the specific size of the fastener. The adjusting assembly is closely connected with the clamping assembly and can be linked according to the adjustment requirements of the clamping assembly, so as to accurately adjust the spacing between the clamping assemblies and ensure that the fastener can be clamped firmly and stably. After the clamping of the fastener is completed, the worker opens the vibration assembly which is located inside the frame 1 away from the top plate 2 to provide a vibration source for the vibration test. With the start of the vibration assembly, a stable vibration source is applied to the fastener, and the vibration test officially starts. During the whole test process, the clamping assembly keeps clamping the fastener stably. The reset spring 27 provides the necessary buffering effect during the vibration test and helps the system to return to the initial state after the vibration test is completed.

[0030] As shown in Figure 1 , Figure 2 , Figure 5 , the clamping assembly includes a movable plate 7 which is movably installed inside the frame 1. One side of the movable plate 7 is fixedly connected with a plurality of reset springs 27. A sliding groove 8 is formed on the movable plate 7. A fixing seat 4 is slidably installed on the sliding groove 8. An extension rod 5 is fixedly installed on the fixing seat 4. Clamping teeth 6 are fixedly installed at both ends of the extension rod 5.

[0031] The sliding groove 8 opened on the movable plate 7 of the clamping assembly allows the fixing seat 4 to slide smoothly. During the preparation of the vibration experiment, the staff first adjusts the position of the two fixing seats 4 in the sliding groove 8 according to the size of the fastener, realizes the preliminary distance adjustment between the clamping assemblies, and ensures that the clamping assemblies can roughly adapt to the width range of the fastener. Then, in order to further improve the accuracy and stability of clamping, the staff will use the adjusting function of the telescopic rod 5 to finely adjust the distance between the two clamping teeth 6. Through the telescopic action of the telescopic rod 5, the clamping teeth 6 can tightly fit the surface of the fastener, no matter how the size of the fastener changes, it can ensure that the clamping assembly can firmly hold the fastener, avoid loosening or falling off during the vibration experiment. This combination of preliminary adjustment and fine adjustment not only improves the adaptability and flexibility of the clamping assembly, but also ensures the accuracy and reliability of the experimental results. It is worth mentioning that the reset spring 27 is fixed at one end of the top plate 2 and connected to the movable plate 7 at the other end, forming a dynamic balance system. The reset spring 27 not only provides a stable support foundation for the movable plate 7 to prevent it from deviating or losing control during vibration, but also can finely adjust the up and down movement of the movable plate 7 through its elastic properties. When the movable plate 7 moves up and down due to vibration, the reset spring 27 will produce a corresponding reaction force according to the change of its compression degree. This reaction force can not only limit the amplitude of the movable plate 7 to prevent it from exceeding the safety range, but also can offset part of the vibration energy to some extent to protect the fastener from excessive impact.
