DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to clearly and completely describe the purpose and technical solution of the present utility model and make its advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0021] Embodiment 1

[0022] Please refer to Figure 1 - Figure 3 For this, the present utility model provides a technical solution: a clamping mechanism, including: a testing machine workbench 1 and threaded holes 3. A plurality of threaded holes 3 are provided on the upper surface of the testing machine workbench 1, and a clamping device 2 can be fixed on each threaded hole 3. A plurality of clamping devices 2 are provided on the testing machine workbench 1, and the positions of the clamping devices 2 can be replaced as needed. Each clamping device 2 includes a first pressing plate 9, a first threaded bolt 10, and a lifting bracket 15. The first pressing plate 9 is arranged on the upper surface of the testing machine workbench 1 and is used to press a thinner and lower object so that it can be placed flat on the testing machine workbench 1. The lifting bracket 15 is fixedly installed on the upper surface of one end of the first pressing plate 9, and the rising bracket is used to raise the lifting pressing plate 21. A first sliding groove 11 is provided on the first pressing plate 9. It is precisely because of the existence of the first sliding groove 11 that the pressing plate can press materials of various sizes and widths. The first threaded bolt 10 passes through the first sliding groove 11 and is slidably connected thereto. One end of the first threaded bolt 10 is threadedly connected to a certain threaded hole 3.

[0023] The lifting bracket 15 is provided with a second sliding groove 20 which is vertically arranged. A lifting pressure plate 21 is slidably connected in the second sliding groove 20. The lifting of the pressure plate can select a suitable position to press the material. A torsion block 24 is fixedly connected to the upper surface of the lifting pressure plate 21. The torsion block 24 ensures that the lifting pressure plate 21 does not rotate when the threaded column 14 is rotated. The upper surface of the torsion block 24 is rotatably connected to the threaded column 14. The threaded column 14 penetrates through the top wall of the second sliding groove 20 and is threadedly connected thereto. Therefore, when the threaded column 14 is rotated, the lifting pressure plate 21 will move up and down. One side of the lifting pressure plate 21 is provided with a second inclined surface 22. The setting of the second inclined surface 22 is to ensure better wiping of the rubber during the experiment. Two fixing rods 23 are fixedly installed in the second sliding groove 20. The fixing rods 23 ensure that the up and down sliding position of the lifting pressure plate 21 does not change. The lifting pressure plate 21 will slide up and down along the two fixing plates, thus ensuring that it always slides within the track. Both fixing rods 23 are slidably connected to the lifting pressure plate 21. One side of the first pressure plate 9 is provided with a first inclined surface 12. The setting of the first inclined surface 12 is also to ensure that after pressing the object, since the object is narrow and only a small part of the area is exposed, the rubber can still accurately wipe on its surface.

[0024] When in use, first determine which end of the clamping device 2 to use according to the thickness of the test material. If the thin end is used, place the material on the workbench 1 of the testing machine, then rotate the first threaded rod and adjust the first pressure plate 9 to press the material, and then rotate the first threaded rod again to tightly press the first pressure plate 9. When the thin end is not enough, the end with the lifting bracket 15 can be used. First, rotate the first threaded rod and adjust the first pressure plate 9 so that the lifting pressure plate 21 is above the material, and then rotate the threaded column 14. The threaded column 14 can drive the lifting of the lifting pressure plate 21, so that the lifting pressure plate 21 presses the object and compresses the material.

[0025] Embodiment 2

[0026] Please refer to Figure 4 Based on Embodiment 1, a rectangular groove 19 is provided at one end of the first pressure plate 9. A telescopic push plate 16 is slidably connected in the rectangular groove 19. The telescopic push plate 16 is used to extrude large objects, so that large objects are not easy to slide. If the object is not convenient to use the lifting pressure plate 21, the telescopic push plate 16 can also be used. Use the telescopic push plates 16 of a pair of clamping devices 2 to squeeze the object in the middle. Two second telescopic rods 17 are fixedly connected to one side of the telescopic push plate 16. The second telescopic rods 17 ensure that the spring 18 does not bend sideways. A spring 18 is sleeved on each second telescopic rod 17. The setting of the spring 18 effectively provides pressure for the telescopic push plate 16.

[0027] When the telescopic push plate 16 needs to be used, first install a clamping device 2, place a large object on one side of the telescopic push plate 16, and loosen the first threaded bolt 10. Then install the second telescopic push plate 16 so that the object is in the middle position, and then fix one of the first threaded bolts 10. Use the other telescopic push plate 16 to squeeze the object. After pressing it tightly, rotate the last first threaded bolt 10. In this way, the object can be tightly squeezed in the middle.

[0028] Embodiment 3

[0029] Please refer to Figure 1 , on the basis of Embodiment 2, a first telescopic rod 6 is slidably connected to the upper part of the test machine workbench 1. The first telescopic rod 6 can be repeatedly telescoped under the drive of the drive device inside the device, and the number of telescoping times is recorded. A support plate 8 is fixedly connected to the first telescopic rod 6. The support plate 8 is used to support the lifting rod 5 so that it can be adjusted. A lifting bolt 7 is slidably connected to the support plate 8. The lifting bolt 7 is lifted and lowered according to the adjustment of the support plate 8. The lifting bolt 7 passes through the support plate 8 and is threadedly connected to the lifting rod 5. One end of the lifting bolt 7 extends into the lifting rod 5 and is threadedly connected to it. A rubber clip 4 is clamped on the lifting rod 5. The rubber clip 4 is used to clamp the rubber. In this way, the telescoping of the first telescopic rod 6 can drive the back-and-forth telescoping of the rubber to realize the wiping action.

[0030] During actual use, first determine which end of the clamping device 2 to use according to the thickness of the test material. If the thin end is used, place the material on the test machine workbench 1, then rotate the first threaded rod and adjust the first pressing plate 9 to press the material, and then rotate the first threaded rod again to press the first pressing plate 9 tightly. When the thin end is not enough, the end with the lifting bracket 15 can be used. First, rotate the first threaded rod and adjust the first pressing plate 9 so that the lifting pressing plate 21 is above the material, and then rotate the threaded column 14. The threaded column 14 can drive the lifting of the lifting pressing plate 21 so that the lifting pressing plate 21 presses the object and presses the material tightly. When the telescopic push plate 16 needs to be used, first install a clamping device 2, place a large object on one side of the telescopic push plate 16, and loosen the first threaded bolt 10. Then install the second telescopic push plate 16 so that the object is in the middle position, and then fix one of the first threaded bolts 10. Use the other telescopic push plate 16 to squeeze the object. After pressing it tightly, rotate the last first threaded bolt 10. In this way, the object can be tightly squeezed in the middle. After clamping the material to be wiped, start the test machine. The first telescopic rod 6 can be repeatedly telescoped under the drive of the drive device inside the device, and the number of telescoping times is recorded. The telescoping of the first telescopic rod 6 can drive the back-and-forth telescoping of the rubber to realize the wiping action.
