Description

Technical Field

[0001] The utility model relates to the technical field of impact resistance performance testing of composite materials, and more specifically, to an impact resistance performance testing device for composite materials. Background Art

[0002] A composite material impact resistance test device is a device specially designed to measure and evaluate the performance of composite materials when subjected to impact loads. This device usually includes a mechanism that can generate impact force (such as a drop hammer, a pendulum or a pneumatic impactor, etc.), and a clamping system for fixing and supporting the composite material sample. By adjusting the parameters of the impact mechanism (such as impact velocity, impact mass or impact energy), the test device can simulate different impact scenarios to evaluate the impact resistance of the composite material. In the current plate impact resistance test, it is usually relied on to manually use a hammer for tapping. However, this traditional test method has significant limitations. First, due to the lack of fixation of the plate during the tapping process, it is prone to vibration and displacement, which not only increases the instability of the test, but also may affect the accuracy of the test results. Secondly, when manually operating the hammer, it is difficult to accurately control the tapping point, which may result in differences in the conditions of each test, further reducing the reliability and consistency of the test data. Therefore, a more advanced and precise test device is needed to ensure that the plate can be accurately and reliably evaluated in the impact resistance test. Utility Model Content

[0026] A clamping block 20 is fixedly installed on the top of the threaded sleeve block 24, and a clamping plate 22 is movably installed inside the clamping block 20. A pull rod 21 is installed on the top of the clamping plate 22, and one end of the pull rod 21 passes through the top of the clamping block 20, and a spring 25 is fixedly installed between the bottom of the clamping block 20 and the top of the clamping plate 22.

[0027] Before testing the composite material, the staff needs to clamp and fix the composite material. By holding the rotating disk 15, the rotating disk 15 drives the bidirectional screw 23 to rotate in the threaded sleeve block 24, so that the threaded sleeve block 24 moves inside the slide groove 19, and the two clamping blocks 20 are driven to move slowly through the threaded sleeve block 24. Now, hold the pull rod 21, and pull the clamping plate 22 inside the clamping block 20 through the pull rod 21, and then squeeze the spring 25 through the clamping plate 22, and drive the spring 25 through the clamping plate 22. Now put the composite material into the clamping block 20, release the pull rod 21, and clamp the clamping plate 22 through the spring 25, and then clamp and fix the composite material through the clamping plate 22, thereby completing the clamping and fixation of the composite material.

[0028] Before testing the composite material, the composite material needs to be clamped and fixed. By holding the rotating disk 15, the rotating disk 15 drives the bidirectional screw 23 to rotate in the threaded sleeve block 24, so that the threaded sleeve block 24 moves inside the slide groove 19, and the two clamping blocks 20 are driven to move slowly through the threaded sleeve block 24. Now, hold the pull rod 21, and pull the clamping plate 22 inside the clamping block 20 through the pull rod 21, and then squeeze the spring 25 through the clamping plate 22, and drive the spring 25 through the clamping plate 22. Now put the composite material into the clamping block 20, release the pull rod 21, and clamp the clamping plate 22 through the spring 25, and then clamp the composite material through the clamping plate 22. Compared with traditional devices, the device is convenient for clamping and fixing the composite material between the spring 25 and the clamping plate 22. The composite material is fixed on the left and right by two clamping blocks 20 to ensure that the composite material is stable and does not shake during the test, thereby accurately measuring the impact resistance of the composite material. This clamping method also expands the test range and adapts to specimens of different shapes and sizes. At the same time, the automatic lifting and lowering functions of the device improve the test efficiency and reduce manual operation time. Most importantly, the stable clamping and fixing ensures the safety of the test process, reduces equipment wear, and extends the service life of the equipment, providing efficient and reliable data support for product design, quality control and research and development.

Cylinders 7 are movably installed on both sides of the limit column 6, and an impact hammer 8 is fixedly installed on the bottom of the limit column 6.

[0032] The staff needs to adjust the height of the impact hammer 8 to simulate various conditions from mild to severe for the composite material, turn on the motor 9, and drive the tooth 2 17 to rotate through the motor 9, and then drive the gear 16 to rotate through the tooth meshing between the tooth 2 17 and the gear 16, and then drive the threaded rod 11 through the gear 16 to drive the internal rotation of the threaded sleeve block 12, so that the threaded sleeve block 12 moves up and down inside the support plate 2 10, and then drive the lifting plate 5 to move up and down slowly through the support plate 2 10, and drive the slider 4 to move inside the support plate 2 and the outer surface of the fixed rod 3 through the lifting plate 5, and then drive the limit column 6 and the impact hammer 8 to be raised through the lifting plate 5, and now turn on the cylinder 7, and release the restriction on the limit column 6 through the cylinder 7. At this time, the limit column 6 and the impact hammer 8 fall vertically on the surface of the material, and the test data is obtained, thereby completing the height adjustment of the impact hammer 8.

[0033] It is necessary to adjust the height of the impact hammer 8 to simulate various conditions from mild to severe of the composite material, turn on the motor 9, drive the tooth 2 17 to rotate through the motor 9, drive the gear 16 to rotate through the tooth 2 17, and then drive the threaded rod 11 through the gear 16 to drive the internal rotation of the threaded sleeve block 12, so that the threaded sleeve block 12 moves up and down inside the support plate 2 10, and then drive the lifting plate 5 to move up and down slowly through the support plate 2 10, and drive the slider 4 to move inside the support plate 2 and the outer surface of the fixed rod 3 through the lifting plate 5, and then drive the limit column 6 and the impact through the lifting plate 5. The hammer 8 is raised. Compared with the traditional device, the device facilitates the adjustment of the height of the impact hammer 8 through the cooperation between the threaded sleeve block 12 and the threaded rod 11, simulating a variety of impact conditions from mild to severe, and realizing a comprehensive evaluation of the impact resistance of the composite material. This method not only avoids the tedious process of frequently replacing impact hammers of different qualities, but also significantly improves the test efficiency. Impact tests are performed at different heights to obtain a series of key data points. These data not only reveal the law of changes in the impact resistance of composite materials with impact energy, but also provide valuable references for material optimization and improvement.

[0035] By holding the tool box 14, the tool box 14 is slowly placed into the limiting groove 13, and the tool box 14 is adjusted through the limiting groove 13. By adding the tool box 14, the operator can quickly find the required tools when needed without having to look around, thereby improving work efficiency.

[0036] Among them, support columns 18 are fixedly installed at the bottom of the motor 9, and the support columns 18 are in the form of a circular array.

[0037] Since the support columns 18 are arranged in a circular array on the top of the motor 9 , it is convenient to support the motor 9 , thereby reducing the shaking of the motor 9 during operation and extending the service life of the motor 9 .

[0038] Among them, a telescopic rod 29 is fixedly installed between the bottom of the lifting plate 5 and the top of the workbench 1, and the telescopic rod 29 presents four shapes of the same size.

[0039] Since the telescopic rods 29 present four shapes of the same size, it is convenient to provide stable support when the lifting plate 5 moves up and down slowly, thereby ensuring the stability of the lifting plate 5 during the up and down movement.

[0040] A support column 27 is fixedly installed at the bottom of the workbench 1 , a base 28 is fixedly installed at the bottom of the support column 27 , and there are four groups of the base 28 and the support column 27 on the top of the workbench 1 .

[0041] Since there are four groups of support columns 27 and bases 28 at the bottom of the workbench 1, it is convenient to support the entire device, ensuring the stability of the device during operation, ensuring that the test device remains stable during the test, and reducing errors caused by shaking or instability of the device.

[0042] An anti-skid pad 26 is fixedly installed on the bottom of the clamping plate 22 , and the anti-skid pad 26 is made of rubber material.

[0043] Since the anti-skid pad 26 is made of rubber material and has excellent wear resistance, it can maintain a long service life even in frequent use and high friction environments and is not easily worn or damaged. In this way, the anti-skid pad 26 is more stable during the clamping of the composite material, thereby improving the use efficiency of the anti-skid pad 26.

[0044] The working principle and use process of this utility model:

[0045] The staff needs to adjust the height of the impact hammer 8 to simulate various conditions from mild to severe for the composite material, turn on the motor 9, and drive the tooth 2 17 to rotate through the motor 9, and then drive the gear 16 to rotate through the tooth meshing between the tooth 2 17 and the gear 16, and then drive the threaded rod 11 through the gear 16 to drive the internal rotation of the threaded sleeve block 12, so that the threaded sleeve block 12 moves up and down inside the support plate 2 10, and then drive the lifting plate 5 to move up and down slowly through the support plate 2 10, and drive the slider 4 to move inside the support plate 2 and the outer surface of the fixed rod 3 through the lifting plate 5, and then drive the limit column 6 and the impact hammer 8 to be raised through the lifting plate 5, and now turn on the cylinder 7, and release the restriction on the limit column 6 through the cylinder 7. At this time, the limit column 6 and the impact hammer 8 fall vertically on the surface of the material, and the test data is obtained, thereby completing the height adjustment of the impact hammer 8.

[0046] Before testing the composite material, the staff needs to clamp and fix the composite material. By holding the rotating disk 15, the rotating disk 15 drives the bidirectional screw 23 to rotate in the threaded sleeve block 24, so that the threaded sleeve block 24 moves inside the slide groove 19, and the two clamping blocks 20 are driven to move slowly through the threaded sleeve block 24. Now, hold the pull rod 21, and pull the clamping plate 22 inside the clamping block 20 through the pull rod 21, and then squeeze the spring 25 through the clamping plate 22, and drive the spring 25 through the clamping plate 22.
