[0034] Please refer to Figure 1 and Figure 2In this embodiment, the guide 2 includes a slide rail 21 and a slider 22. The slide rail 21 is installed on the upper part of the base 1, and the slider 22 is slidably installed on the upper part of the slide rail 21. The loading platform 4 is installed on the upper part of the slider 22. The cooperation of the slide rail 21 and the slider 22 achieves a good guiding effect. A support plate 11 is installed on the side of the base 1 adjacent to the slide rail 21, and a photoelectric switch 12 is installed on the side of the support plate 11. The photoelectric switch 12 can be used to more accurately control the position of the loading platform 4, so that it can move to the designated position.

[0035] Please see Figure 1 and Figure 4 In this embodiment, the loading platform 4 includes a base plate 41 and a connecting plate 42. The base plate 41 is installed on the upper part of the slider 22, and the connecting plate 42 is installed on the upper part of one side of the base plate 41. In order to enhance the connection strength between the connecting plate 42 and the base plate 41, a reinforcing plate 44 is installed at the connection part of the base plate 41 and the connecting plate 42. The cross section of the reinforcing plate 44 is L-shaped. A through hole 43 for the specimen to pass through is opened at the lower part of the connecting plate 42. The third cylinder 8 is installed on the side of the base plate 41, the unloading plate 9 is located on one side of the through hole 43, the second cylinder 6 is installed on one side of the base plate 41, and the loading plate 7 is located on the other side of the through hole 43.

[0036] To facilitate the replacement of the material box 5, a quick-change interface 45 is provided on the side of the base plate 41 near the connecting plate 42, and the material box 5 is installed on the upper part of the quick-change interface 45; to facilitate the placement of test pieces, the upper part of the material box 5 is open, and a notch 51 is provided on one side of the material box 5, which makes it easier to observe the remaining amount of test pieces and facilitates the replenishment of test pieces; a slot is opened on the side of the material box 5, into which the quick-change interface 45 can be inserted.

[0038] Specifically, the working principle of the automatic loading and unloading system of the fully automatic three-point bending test bench is as follows: the base is connected to the moving three-point bending test bench, the sample to be tested is placed in the material box 5, and the material box 5 and the loading platform 4 adopt a quick-change interface 45 for easy replacement and installation. The first cylinder 3 drives the entire loading platform 4 to move forward to the designated position, the second cylinder 6 drives the loading slide 71 to push the loading plate 7 to move, and then pushes the sample in the material box 5 to the test center position of the three-point bending test bench. Then the first cylinder 3 drives the loading platform 4 to move backward to the braking position. After the test is completed, the third cylinder 8 drives the unloading plate 9 to the designated unloading height, and then the first cylinder 3 drives the unloading plate 9 to move forward to push the sample out of the test area. Then the action is repeated to achieve the purpose of continuous sample loading and unloading. This mechanism successfully improves the sample loading efficiency of three-point bending test specimens, reduces the labor intensity of operators, and avoids human error.

[0039] It should be noted that the model and specifications of photoelectric switch 12, first cylinder 3, second cylinder 6 and third cylinder 8 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.
