Description

Technical Field

[0002] During the impact test of an object by an existing device, the punch is dropped vertically into the protective frame and hits the top of the object. By observing the damage to the object, the performance and condition of the object when it was impacted can be inferred.

[0003] The impact test platform of the above-mentioned device cannot be accurately aligned with the test target, resulting in deviations in the impact test results. The main reason is that the accuracy of the impact test depends on the impact force or energy being applied to the test object in the correct position and direction. If the impact point cannot be accurately aligned, the impact force will not be transmitted to the test object in the expected manner, resulting in inaccurate test results. Therefore, an impact test platform that can adjust the impact force is needed. Utility Model Content

[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Impact testing platforms are key tools for evaluating the performance and durability of materials, components, and products when subjected to impact or collision. Their primary function is to assess the impact resistance of materials, components, or products by simulating the impact or collision conditions found in real-world environments. These tests reveal a material's load-bearing capacity, degree of deformation, and potential failure modes under impact. In short, impact testing platforms, by simulating various impact conditions and evaluating the performance of materials and products in real-world use scenarios, are crucial tools for ensuring product quality and safety.

[0025] The impact test platform of existing devices cannot be accurately aligned with the test target, which may lead to deviations in the impact test results. The main reason is that the accuracy of the impact test depends on the impact force or energy being applied to the test object at the correct position and direction. If the impact point cannot be accurately aligned, the impact force will not be transmitted to the test object in the expected way, resulting in inaccurate test results. Figures 1-4 The embodiment provides an impact testing platform capable of adjusting impact force, including a base 1 and two support plates 2 symmetrically fixed on the top of the base 1, with a protective frame 3 fixedly connected between the two support plates 2.

[0026] refer to Figure 2-Figure 3As shown, the opposite sides of the two support plates 2 are provided with a lifting mechanism 4 for adjusting the impact force, and the lifting mechanism 4 includes a side concave plate 41 fixed to the side of the support plate 2, the inner wall of the side concave plate 41 is fixedly connected with an electric slide rail 42, and the outer wall of the electric slide rail 42 is slidably connected with an adjustment plate 43, and a top plate 44 fixedly connected to the bottom of the C-shaped frame 51 is fixedly connected between the adjustment plates 43. The center part of the top plate 44 is connected to the C-shaped frame 51, so that when the object falls and the impact force of the object is adjusted, the electric slide rail 42 is started to make the adjustment plate 43 slide up or down on the outer wall of the electric slide rail 42, and then the top plate 44 drives the control mechanism 5 at its top to adjust the height. The adjustment of the height of the control mechanism 5 can realize the adjustment of the impact force of the object, and can significantly improve the flexibility of adjusting the impact force of the object. By changing the height, the speed and kinetic energy of the object when falling can be changed, thereby affecting the impact force generated when the object hits the hit plate 6. For example, if the lifting mechanism 4 allows the object to fall from a higher height, it will have greater kinetic energy and impact force. Conversely, if the object is released from a lower height, its kinetic energy and impact force will be reduced. This flexibility allows the impact test to be precisely controlled and adjusted according to specific test needs and requirements to simulate actual application scenarios under different impact conditions.

[0027] refer to Figure 2-Figure 4As shown, the impact test platform of the above device cannot be accurately aligned with the test target, resulting in deviations in the impact test results. The main reason is that the accuracy of the impact test depends on the impact force or energy being applied to the test object in the correct position and direction. If the impact point cannot be accurately aligned, the impact force will not be transmitted to the test object in the expected manner, resulting in inaccurate test results. In order to ensure the accuracy and reliability of the impact test, the following settings are made: a control mechanism 5 for performing impact testing on the object is provided on the top of the protective frame 3, and the control mechanism 5 includes two C-shaped symmetrically arranged on the top of the protective frame 3. Frame 51, the two C-shaped frames 51 are each provided with a storage plate 52 inside, the inner wall of the storage plate 52 is fixedly connected to a rotating shaft 53 that is rotatably connected to the inner wall of the C-shaped frame 51, and the outer walls of both ends of the rotating shaft 53 are sleeved with a torsion spring 54, and the two ends of the torsion spring 54 are respectively fixedly connected to the C-shaped frame 51 and the rotating shaft 53, and the top of the C-shaped frame 51 is fixedly connected to a crossbeam 510, and the top of the storage plate 52 is in contact with the bottom of the crossbeam 510. After an object falls from the top of the storage plate 52, the storage plate 52 is reset by the torsion spring 54. In order to ensure the horizontality of the storage plate 52 after it is reset, a special crossbeam 510 is provided to limit the top of the storage plate 52. A telescopic assembly is provided at one end of the storage plate 52 close to the C-shaped frame 51 for removing the horizontal supporting force of the storage plate 52 and rotating the storage plate 52 downward. The telescopic assembly includes a clamping frame 58 fixed to the inner wall of the C-shaped frame 51, and an electromagnet 59 is fixedly connected to the inner wall of the clamping frame 58. The side of the storage plate 52 is fixedly connected to the mounting frame 55, and the inner wall of the mounting frame 55 is fixedly connected to the spring 56. The end face of the spring 56 is fixedly connected to the magnet 57. When the electromagnet 59 is energized, it is attracted to the magnet 57. The electromagnet 59 is started to move the magnet 57 in and out of the mounting frame 55 and the tension spring 56 is attracted to the electromagnet 59, forming a clamping connection between the magnet 57 and the clamping frame 58, providing support for the horizontal level of the storage plate 52. After placing the object on the top of the storage plate 52, the power supply of the electromagnet 59 is turned off, and the magnet 57 is reset by the spring 56. The storage plate 52 tilts downward without support. The object on the top of the storage plate 52 falls vertically downward to the top of the impact plate 6 in the protective frame 3 due to the action of gravity. By observing the damage to the object, the impact condition of the object can be judged without the need for punching blocks.

[0028] refer to Figure 1-Figure 2As shown, the inner wall of the protective frame 3 is provided with a striking plate 6, and a rectangular groove is provided on the front side of the protective frame 3. The striking plate 6 passes through the inner wall of the rectangular groove and extends to the interior of the protective frame 3. Two sliders are symmetrically fixedly connected on both sides of the striking plate 6, and two sliding grooves are symmetrically provided on the inner wall of the protective frame 3 for the sliders to move laterally. The striking plate 6 can be pulled out and replaced with striking plates 6 of different materials. Replacing striking plates 6 of different materials can improve the flexibility and applicability of the impact test. This is because striking plates 6 of different materials have different energy absorption capabilities. For example, some materials may absorb impact energy more effectively, thereby reducing the rebound or shear force of the object during the impact process, making the test process more accurate, and the hardness and elastic modulus of the material affect the rigidity and deformation behavior of the striking plate 6. Harder materials will cause greater rebound force, while softer materials can absorb more energy and reduce the rebound of the object.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
