[0025] The clamping mechanism 4 includes a motor 401, which is arranged at the lower end of the table top 1. The lower surface of the motor 401 is in contact with a fixed plate 402, and the upper surface of the fixed plate 402 is evenly distributed with fixed rods 403, and the upper surface of the fixed rod 403 is fixedly connected to the table top 1. The rotating shaft of the motor 401 is connected to the rotating rod 404, and the upper end of the rotating rod 404 is rotatably connected to the inner wall of the cavity 3. A connecting plate 405 is fixedly sleeved on the surface of the rotating rod 404, and four groups of connecting rods 406 are hinged on the lower surface of the connecting plate 405, and the four groups of connecting rods 406 are all arranged in an L-shaped structure, and the ends of the four groups of connecting rods 406 that are away from each other are fixedly connected with a sliding rod 407. The plate 1 is provided with a slide groove for the slide bar 407 to move. The upper surfaces of the four groups of slide bars 407 are all fixedly connected with a clamping plate 408, and the four groups of clamping plates 408 are all arranged on the upper surface of the table plate 1. Through the rotation of the motor 401, the rotating rod 404, the connecting plate 405, the connecting rod 406 and the slide bar 407 cooperate with each other to drive the four groups of clamping plates 408 to approach each other, which can adapt to metal organic framework materials of different shapes and sizes, providing a greater degree of freedom in the test. The metal organic framework material is clamped by the clamping plate 408, which ensures the stable clamping of the metal organic framework material during the test, helps to avoid test errors, and provides a reliable data basis.

[0026] The upper surface of the table top 1 is embedded with a center point 5, and the position of the center point 5 corresponds to the motor 401. The stamping mechanism 7 includes a hydraulic cylinder 701, which is fixedly mounted on the lower surface of the support frame 6.

The threaded punch head 703 is convenient for subsequent disassembly and maintenance.

[0027] The camera mechanism 8 includes a vertical rod 801, which is fixedly mounted on the upper surface of the table top 1. A lifting rod 802 is movably inserted at the upper end of the vertical rod 801. A locking bolt is inserted at the front surface of the vertical rod 801.

The lens is responsible for imaging and focusing, and is an extremely important part of the camera system. Its quality directly affects the clarity and quality of the image. The VCM motor, i.e., a voice coil motor, is used to change the image distance and realize the automatic focusing function of the lens. The base plays a role in fixing the lens to ensure the stability of the imaging system. The IR filter is used to filter out unnecessary infrared light to avoid color deviation in the image. Image sensors, such as CMOS or CCD, are responsible for converting light signals passing through the lens into electrical signals, which is the core step of digital imaging. Finally, the circuit board controls the power supply and processes signal transmission to ensure that the image data can be correctly read and stored. In the present application, the specific model of the high-speed camera 804 can be selected according to actual needs, and its specific circuit connection relationship can be kept consistent with the prior art, which will not be elaborated here. The hinge between the support rod 803 and the high-speed camera 804 is wrapped with a rubber pad. The height is driven by adjusting the lifting rod 802. The high-speed camera 804 on the support rod 803 continuously captures images at a high frame rate to capture the details of fast-moving objects. By adjusting the high-speed camera 804, the impact process can be observed at different heights and angles, and the details and deformation of the frame material during the stamping process can be captured, providing a comprehensive data analysis basis. The rubber pad can play a fixing role through friction after adjusting the angle of the high-speed camera 804, and can maintain the stability of the high-speed camera 804.

[0028] The working principle of the metal organic framework material impact performance test device provided by the utility model is as follows:

[0029] When in use, the metal organic framework material is placed on the center point 5, and the motor 401 drives the rotating rod 404 and the connecting plate 405 to rotate, and the connecting plate 405 drives the connecting rod 406 and the sliding rod 407 to move, so that the four groups of clamping plates 408 are close to each other to clamp the metal organic framework material, and the hydraulic cylinder 701 drives the punch head 703 to move downward to perform an impact performance test on the metal organic framework material. After the lifting rod 802 is adjusted to a suitable height, it is fixed by a locking bolt, and then the height camera 804 is adjusted to a suitable angle to record the stamping process of the metal organic framework material. The above is the entire working principle of the utility model.
