[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clear that 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.
[0022] The utility model provides Figures 1 to 4 The device for testing the impact resistance of irregular components shown in the figure includes a base 1 for placing the test component. A support plate 12 is fixedly connected to the outer wall of the base 1. A vertical plate 13 is fixedly connected to the upper surface of the support plate 12. A square plate 15 is slidably mounted on the vertical plate 13. An electromagnet 16 is fixedly connected to the lower surface of the square plate 15. The electromagnet 16 is located at the end of the square plate 15 away from the vertical plate 13. During use, an impact hammer is placed against the bottom of the electromagnet 16. The electromagnet 16 is then activated. The magnetic force generated by the electromagnet 16 attracts the impact hammer, securing it to the bottom of the electromagnet 16. The electromagnet 16 is then turned off, eliminating the suction force. The impact hammer freely falls onto the test component, and the damage to the test component is observed, completing the test. The position of the square plate 15 on the vertical plate 13 can be adjusted to position the impact hammer at different heights, thereby improving the applicability of the impact resistance testing device.
[0023] In order to prevent the square plate 15 from sliding upward and directly sliding out from the top of the vertical plate 13 , the top of the vertical plate 13 is fixedly connected to a limiting block 14 .
[0024] To secure the position of the square plate 15, a threaded hole 17 is provided on the square plate 15. A screw 18 is threadedly connected to the threaded hole 17. The screw 18 is pressed into engagement with the vertical plate 13. By rotating the screw 18, its end is pressed against the vertical plate 13, securing the position of the square plate 15. A scale can be provided on the vertical plate 13 to ensure precise measurement of the impact hammer's height, improving detection accuracy.
[0025] Considering that after the impact hammer performs an impact test on the test component, it will bounce to a certain height, and this bounce height may cause a secondary impact on the test component, resulting in inaccurate test results. At the same time, it is difficult to grasp the rebound direction of the impact hammer for some irregularly shaped test components, which can easily bring safety hazards to external equipment and operators. A protective cover 2 is fixedly connected to the upper surface of the base 1. The protective cover 2 includes a lower cover body 3 and an upper cover body 4. The upper cover body 4 is integrally formed on the top of the lower cover body 3. The inner diameter of the upper cover body 4 gradually decreases from bottom to top to prevent the impact hammer from rebounding to a high height. Setting the protective cover 2 as two parts, the lower cover body 3 and the upper cover body 4, can prevent the impact hammer from rebounding at will, reduce its rebound height, avoid secondary impact on the test component, and prevent fragments of the test component from splashing, thereby achieving the purpose of safety protection.
[0026] The opening at the top of the upper cover 4 does not affect the placement of the test component on the base 1 or the free fall of the impact hammer. Furthermore, the lower cover 3 and upper cover 4 can be configured as an assembled structure, adjustable for specific applications. A plurality of airbags 5 are fixedly attached to the inner wall of the protective cover 2. Made of high-strength material, these airbags 5 are evenly distributed around the inner wall of the protective cover 2. Circular grooves 6 are defined on the sidewalls of the protective cover 2, corresponding to the airbags 5.
[0027] A buffer assembly that cooperates with the airbag 5 is provided inside the circular groove 6. The buffer assembly includes a cylinder 7, a first circular hole 8, a slider 10 and a spring 11. The cylinder 7 is fixedly connected to the inside of the circular groove 6. The first circular hole 8 is opened on one end of the cylinder 7 close to the airbag 5. The cylinder 7 is connected to the airbag 5 through the first circular hole 8. The slider 10 is slidably connected to the inside of the cylinder 7. The spring 11 is located inside the cylinder 7. One end of the spring 11 is fixedly connected to the slider 10, and the other end of the spring 11 is fixedly connected to the inner wall of the cylinder 7.
[0028] A second circular hole 9 is formed at one end of the cylinder 7 away from the airbag 5 .
[0029] When the impact hammer and the fragments of the test component rebound, they will contact and squeeze the airbag 5, and the airbag 5 will perform the first force unloading and buffering; at the same time, the gas inside the airbag 5 enters the cylinder 7 through the first circular hole 8, causing the slider 10 to move toward the second circular hole 9 and squeeze the spring 11 to contract, performing the second force unloading and buffering, thereby protecting the protective cover 2 and extending its service life. At the same time, due to the force unloading and buffering effect of structures such as the airbag 5, the impact force of the second fall of the impact hammer can be reduced.
