DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] The utility model provides a kind of adjustable anti-impact detection device, as Figures 1-4 As shown in a kind of adjustable anti-impact detection device, including top plate 1, the middle part of top plate 1 upper surface is provided with installation slot, the inside fixed mounting of installation slot is pulled stretch subassembly, the edge of top plate 1 lower surface is fixedly connected with guide rod 2, the outer surface of guide rod 2 is slidably connected with connecting plate 3, the middle part of connecting plate 3 one side is fixedly installed with adjusting subassembly;

[0027] The adjustment assembly includes a first motor 4, one side of which is fixedly mounted in the middle of one side of the connecting plate 3. The output end of the first motor 4 is fixedly connected to a first threaded rod 5. The outer surface of the first threaded rod 5 is threadedly connected to a first mounting plate 6. A second motor 7 is fixedly mounted in the middle of one side of the first mounting plate 6. The output end of the second motor 7 is fixedly connected to a second threaded rod 8. The outer surface of the second threaded rod 8 is threadedly connected to a second mounting plate 9. When an external power source is connected, the first motor 4 is started, driving the first threaded rod 5 to rotate, causing the first mounting plate 6 to move left and right on its outer surface. Then, when an external power source is connected, the second motor 7 is started, driving the second threaded rod 8 to rotate, causing the second mounting plate 9 to move back and forth on its outer surface. This allows for convenient and quick adjustment of the position of the impact hammer 11, enabling adjustment of the impact detection position without being affected by range. It can effectively adapt to different testing needs and material properties, improve the applicability of the test, and is simple to operate, which helps to ensure testing efficiency and the accuracy and consistency of the test results.

[0028] An electromagnetic block 10 is fixedly connected to the lower surface of the second mounting plate 9. An impact hammer 11 is adsorbed onto the lower surface of the electromagnetic block 10. A support frame 12 is fixedly connected to the outer surface of the impact hammer 11. When the electromagnetic block 10 is electromagnetic, it can adsorb the impact hammer 11 and lift it to a suitable height. When the electromagnetic block 10 is demagnetized, the impact hammer 11 falls and achieves free fall for impact detection. The support frame 12 supports the impact hammer 11 to prevent it from tilting completely, which would make it difficult for the electromagnetic block 10 to accurately adsorb it next time.

[0029] The tensioning assembly includes a third motor 13, the outer surface of which is fixedly installed inside the mounting groove. A winding spool 14 is fixedly connected to the output end of the third motor 13. A steel cable 15 is wound around the outer surface of the winding spool 14. One end of the steel cable 15 is connected to the middle of the upper surface of the connecting plate 3. When an external power source starts the third motor 13, it drives the winding spool 14 to rotate. The steel cable 15 drives the connecting plate 3 to move up and down, thereby adjusting the height of the impact hammer 11. This allows the operator to select a suitable impact height according to experimental requirements, thus simulating impact conditions under various practical application scenarios, detecting the impact force at different heights, and obtaining more comprehensive measurement data to ensure the accuracy of the measurement data.

[0030] The bottom end of the guide rod 2 is fixedly connected to a base plate 16. Both sides of the upper surface of the base plate 16 are fixedly connected to fixing components. The fixing components include a vertical plate 17. The lower surface of the vertical plate 17 is fixedly connected to one side of the upper surface of the base plate 16. A spring 18 is fixedly connected to the inner side of the vertical plate 17. One end of the spring 18 is fixedly connected to a push plate 19. The base plate 16 allows the product to be tested to be on the same plane. The spring 18 then presses against the push plate 19 to push and fix the product to be tested, preventing displacement during the testing process and affecting the accuracy of the test data.

[0031] Both ends of one side of the connecting plate 3 are rotatably connected with first limiting rods 20, both ends of one side of the first mounting plate 6 are rotatably connected with second limiting rods 21, the first limiting rods 20 can limit the first mounting plate 6 to avoid its skewing when the first threaded rod 5 rotates, the second limiting rods 21 can limit the second mounting plate 9 to avoid its skewing when the second threaded rod 8 rotates, so as to guarantee the horizontal setting of the impact hammer 11 when adjusting its position.

[0032] Working steps: first, the product to be detected is placed above the bottom plate 16, the spring 18 extrudes the push plate 19, so as to push and fix the product to be detected, then the external power source starts the third motor 13 to drive the winding shaft 14 to rotate, which can drive the connecting plate 3 to move up and down through the steel cable 15, so as to drive the impact hammer 11 to be at the required height, secondly, the external power source starts the first motor 4 to drive the first threaded rod 5 to rotate, the first limiting rod 20 limits the first mounting plate 6 to move left and right on its outer surface, then the external power source starts the second motor 7 to drive the second threaded rod 8 to rotate, the second limiting rod 21 limits the second mounting plate 9 to move forward and backward on its outer surface, so as to make the impact hammer 11 at the required position, finally, the electromagnetic block 10 is demagnetized, the impact hammer 11 falls to realize free fall for impact detection, and the supporting frame 12 supports the impact hammer 11 to avoid its complete skewing, which causes the electromagnetic block 10 to be difficult to accurately adsorb it next time.

[0033] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
