Description

Technical Field

[0001] This utility model relates to the technical field of impact performance testing devices, specifically a metal-organic framework material impact performance testing device. Background Technology

[0002] Metal-organic frameworks (MOFs) are a class of crystalline porous materials with a periodic network structure formed by the self-assembly of metal ions or metal clusters and organic ligands. MOFs have unique structures and properties, such as high porosity, large specific surface area, high thermal stability, as well as excellent adsorption performance and controllability. When performing stamping performance testing on MOFs, an impact performance testing device for MOFs is required.

[0003] Existing testing devices lack an effective adaptive clamping structure, which means that a single type of testing device can only effectively fix and test materials of one specific size. When testing materials of different shapes, different sizes of devices are required, which not only reduces the testing efficiency for different materials but also increases testing costs and reduces the overall practicality and flexibility of the device.

[0004] Compared with patent application CN222482027U, this utility model provides a testing device for the impact performance of metal-organic framework materials. It includes a table for placing the metal-organic framework material and a support plate for support. By incorporating a camera mechanism, this utility model can record subtle changes during the impact process, aiding in the analysis of the impact effect. The high-speed camera recording provides intuitive video information, offering crucial data support for further analysis and research.

[0005] The above solution has a camera recording function, but the specifications of the fixing plate in the above solution are fixed. As a result, a device of one specification can only fix materials of one appearance. When it is necessary to fix materials of different shapes, it is necessary to replace the entire device, which reduces the testing efficiency of different materials, increases the testing cost, and reduces the practicality and flexibility of the device.

[0006] Based on this, a test apparatus for the impact performance of metal-organic framework materials is provided, which can eliminate the drawbacks of existing apparatuses. Utility Model Content

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] In one embodiment, such as Figures 1-5 As shown, a metal-organic framework material impact performance testing device includes a support platform 1, and a support frame 2 is fixedly installed on the outer wall of the support platform 1.

[0036] A stamping assembly is disposed in the middle of the upper surface of the support frame 2 and is used to stamp the material.

[0037] An adaptive clamping assembly, located above the support platform 1, is used to fix materials of different shapes.

[0038] A drive assembly is located in the middle of the lower surface of the support platform 1 and is used to drive the adaptive clamping assembly to clamp the material.

[0039] The mounting components are symmetrically arranged on the outer wall of the stamping assembly and are used to disassemble and assemble the internal parts of the stamping assembly.

[0040] In this embodiment, when a stamping test is required on the material, the material is first placed at the center of the support platform 1. At this time, the drive component starts to run, and the drive component will drive the four adaptive clamping components to move towards the center synchronously. When the adaptive clamping components touch the outside of the material, the material can be effectively fixed by the adaptive clamping components. In addition, the adaptive clamping components can also effectively clamp materials with different shapes and appearances, which effectively improves the overall practicality and flexibility of the device. After the material is fixed, the stamping component starts to run, and the stamping component will stamp the material. At this time, the material can be stamped. Through the setting of the installation components, it is convenient for the staff to replace the stamping head 5 without the need for the staff to use bolts or hand-tightening, which effectively improves the disassembly and assembly efficiency of the stamping head 5, reduces the workload of the staff, and further improves the overall practicality of the device.

[0041] In one embodiment, such as Figure 1 and Figure 2 As shown, the stamping assembly includes a hydraulic cylinder 3 fixedly installed in the middle of the upper surface of the support frame 2. The telescopic end of the hydraulic cylinder 3 is fixedly connected to a mounting sleeve 4. The mounting sleeve 4 has a mounting plate 22 inside. The bottom of the mounting plate 22 is fixedly connected to a stamping head 5. When it is necessary to perform a stamping test on the material, the hydraulic cylinder 3 starts to run. At this time, the hydraulic cylinder 3 will drive the mounting sleeve 4 and the mounting plate 22 to move synchronously. The mounting plate 22 will then drive the stamping head 5 to move synchronously. At this time, the material can be effectively stamped by the stamping head 5.

[0042] In one embodiment, such as Figures 1-3 As shown, the adaptive clamping assembly includes multiple clamping blocks 6 located above the support platform 1. Damping rods 13 are evenly spaced on the inner wall of each clamping block 6. Moving blocks 14 are fixedly connected to the telescopic ends of each damping rod 13. Clamping heads 16 are fixedly connected to the other side of each moving block 14. Return springs 15 are sleeved on the outside of each damping rod 13, and the return springs 15 abut against the moving blocks 14 and clamping blocks 6. When material needs to be fixed, the drive assembly starts operating. At this time, the drive assembly drives the four clamping blocks 6 to move synchronously towards each other. When the clamping heads 16 abut against the outer wall of the material… The clamping head 16 continues to move closer to the center. At this time, the clamping head 16 will drive the moving block 14 to move synchronously. The moving block 14 will then squeeze the damping rod 13 and the return spring 15 synchronously. When the clamping head 16 is completely in contact with the outer wall of the material (that is, when part of the damping rod 13 has been compressed to the limit position), the materials of different shapes can be fixedly clamped by the cooperation between the clamping head 16 and the clamping block 6, thereby avoiding displacement of the material during the test. After the material is removed, the return spring 15 will drive the moving block 14 and the clamping head 16 to reset synchronously.

[0043] In one embodiment, such as Figures 1-3 As shown, the multiple clamping heads 16 are all made of rubber. The rubber material of the clamping heads 16 can increase the friction between the clamping heads 16 and the material, thereby effectively improving the fixing effect of the material. On the other hand, it can effectively protect the outer wall of the material.

[0044] In one embodiment, such as Figure 2 and Figure 4 As shown, the drive assembly includes a drive disk 17 fixedly connected to the center of the lower surface of the support platform 1. A drive motor 18 is fixedly connected to the bottom of the drive disk 17. The output shaft of the drive motor 18 is fixedly connected to a rotating rod 19 via a coupling. The other end of the rotating rod 19 is rotatably connected to the inner wall of the drive disk 17. A first bevel gear 20 is fixedly connected to the outer wall of the rotating rod 19. Multiple base plates 7 are fixedly connected to the bottom of the support platform 1. Threaded rods 8 are rotatably connected to the outer walls of the multiple base plates 7. The other ends of the multiple threaded rods 8 extend into the interior of the drive disk 17 and are fixedly connected to a second bevel gear 21 that meshes with the first bevel gear 20. The outer walls of the multiple threaded rods 8 are all threaded... The support platform 1 has a guide groove for the threaded blocks 9 to move inside. The upper surfaces of the multiple threaded blocks 9 are fixedly connected to the bottom of multiple clamping blocks 6. When it is necessary to fix the material, the drive motor 18 starts to run. At this time, the drive motor 18 will drive the rotating rod 19 and the first bevel gear 20 to rotate synchronously. The first bevel gear 20 will then drive multiple second bevel gears 21 and multiple threaded rods 8 to rotate synchronously. At this time, the threaded blocks 9 will move synchronously outside the threaded rods 8, driving the multiple clamping blocks 6 to move towards the center synchronously. At this time, the material can be effectively clamped by the cooperation between the clamping blocks 6 and the clamping head 16.

[0045] In one embodiment, such as Figure 2 As shown, multiple support plates 10 are fixedly connected to the bottom of the support platform 1. A guide rod 11 is fixedly connected between every two support plates 10. A guide plate 12 is slidably connected to the outside of the multiple guide rods 11. The upper surface of every two guide plates 12 is fixedly connected to the bottom of multiple clamping blocks 6. The support platform 1 has a movable groove for the guide plate 12 to move inside. During the movement of the clamping block 6, the guide plate 12 will also move synchronously on the outer wall of the guide rod 11. At this time, the guide rod 11 and the guide plate 12 can effectively play a limiting and guiding role, thereby further improving the stability of the clamping block 6 during the movement.

[0046] In one embodiment, such as Figure 2 and Figure 5As shown, the mounting assembly includes fixed sleeves 23 symmetrically arranged on the outer wall of the mounting sleeve 4. A fixed rod 24 is located inside the fixed sleeve 23. A pull ring is fixedly connected to one end of the fixed rod 24. An abutment plate 25 is fixedly connected to the outer wall of the fixed rod 24. An abutment spring 26 is sleeved on the outside of the fixed rod 24, and the abutment spring 26 abuts against the abutment plate 25 and the fixed sleeve 23. Slots for the fixed rod 24 to move are provided on the contact surface between the fixed sleeve 23 and the mounting sleeve 4, as well as inside the mounting plate 22. When the punch head 5 needs to be installed, simply pull the pull ring first. At this time, the pull ring will drive the fixed rod 24 and the abutment plate 25. The contact plate 25 moves synchronously. During the movement of the contact plate 25, it compresses the contact spring 26. At this time, the mounting plate 22 is inserted into the interior of the mounting sleeve 4, and then the pull ring is released. At this time, the contact spring 26 returns to its original position, driving the contact plate 25 and the fixing rod 24 to move synchronously. When the fixing rod 24 is inserted into the slot inside the mounting plate 22, the punch head 5 can be fixedly installed. At the same time, it is convenient for the staff to disassemble and replace the punch head 5 without the need for the staff to use bolts or hand-tightening, which effectively improves the disassembly and assembly efficiency of the punch head 5 and reduces the workload of the staff.

[0047] In one embodiment, such as Figure 1 and Figure 2 As shown, high-speed cameras 27 are fixedly installed on both sides of the inner wall of the support frame 2. The high-speed cameras 27 can effectively record the stamping test process of the material.

[0048] The above embodiments disclose a metal-organic framework material impact performance testing device. When a stamping test is required, the material is placed at the center of the support platform 1. At this time, the drive motor 18 starts running, and the drive motor 18 drives the four clamping blocks 6 to move towards the center synchronously. When the clamping head 16 touches the outside of the material, the material can be effectively fixed through the cooperation of the clamping head 16 and the clamping block 6 assembly. It can also effectively clamp materials with different shapes and appearances, effectively improving the overall practicality and flexibility of the device. After the material is fixed, the hydraulic cylinder 3 starts running, and the hydraulic cylinder 3 drives the stamping head 5 to stamp the material, thereby enabling the stamping test. The setting of the fixing rod 24 makes it easy for the staff to replace the stamping head 5 without the need for the staff to use bolts or hand-tightening, effectively improving the disassembly and assembly efficiency of the stamping head 5, and further improving the overall practicality of the device.
