[0018] For the convenience of understanding the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present utility model more thorough and comprehensive.

[0019] It should be noted that when an element is referred to as being "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right", "top", "bottom", "bottom end", "top end" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0021] A clamping tool for a tensile specimen after fracture, as Figure 1-2 shown, includes: a machine body 2, a slide rail 3, a clamping support 4, a slide block 6, a screw 7 and a baffle 8. The machine body 2 is L-shaped, a slide rail 3 is provided on the machine body 2, the clamping support 4 and the slide block 6 are slidably disposed on the slide rail 3, a baffle 8 is provided at one end of the slide rail 3, and the screw 7 passes through the baffle 8 at one end of the slide rail 3 and abuts against the slide block 6.

[0022] Specifically, the slide rail 3 is a high-precision guide rail to ensure the straightness and wear resistance of the slide rail 3. There are two clamping supports 4 and a slider 6 arranged on the slide rail 3. The slide rail 3 is arranged on the fuselage 2. Since the fuselage 2 is L-shaped, one end of the slide rail 3 abuts against the vertical part of the fuselage 2, and the other end abuts against one side of the baffle 8 fixedly arranged on the fuselage 2 with screws to prevent the clamping support 4 from slipping off the slide rail 3 during the test; both clamping supports 4 are fixed on the slide rail 3 through locking screws to ensure the stability of clamping. Adjusting components 5 are arranged on both clamping supports 4, and the adjusting components 5 can be adjusted according to the diameter of the specimen 9 to meet different diameter requirements.

[0023] Furthermore, the clamping support 4 is made of high-strength material to ensure that it does not deform or get damaged during the test.

[0024] As Figure 1-2 shown, there is a groove inside the vertical part of the fuselage 2, and there is also a groove on the opposite side of the slider 6 and the fuselage 2. One end of the specimen 9 is clamped on the clamping support 4, and the other end is placed in the corresponding groove on the opposite side, ensuring the stability of the specimen 9 after fracture.

[0025] The baffle 8 is provided with a threaded hole for cooperating with the screw rod 7. The screw rod 7 passes through the threaded hole on the baffle 8 and abuts against the slider 6. The screw rod 7 is a Z-shaped component provided with a handle. When in use, hold the handle position of the screw rod 7 by hand and push the screw rod 7 to make the screw rod 7 rotate in the threaded hole on the baffle 8, thereby pushing the slider 6 to move.

[0026] When the tensile specimen post-fracture clamping tool provided by the present utility model is working, place the clamping tool on the workbench 1, place one end of the two fractured tensile specimens 9 on the two clamping supports 4 respectively, and place the other end in the corresponding grooves of the fuselage 2 and the slider 6 respectively. Adjust the position of the clamping support 4 to ensure that the two fractured parts of the specimen 9 are aligned. Pass the screw rod 7 through the baffle 8 to abut against the slider 6, and push the screw rod 7 to rotate it to push the slider 6 to abut against one end of the fractured specimen 9. After the two parts of the specimen 9 are tightly spliced together by the top pressure, subsequent measurement and analysis work can be carried out.

[0027] A post - fracture clamping tool for tensile specimens provided by the present utility model, through the combination of a high - precision guide rail 3 and locking screws, not only ensures the straightness and stability of the slide rail 3, but also ensures the stable clamping of the specimen 9 through the locking mechanism, improving the measurement accuracy and operation convenience; by designing an adjusting component 5 for specimens with different diameters on the clamping support 4, it can adapt to the clamping requirements of various specifications of specimens, improving the applicability and versatility of the device; by adjusting the position of the clamping support 4 and the top pressure of the screw 7, precise alignment and tight splicing of both ends of the fractured specimen 9 can be achieved, ensuring the accuracy of subsequent measurement and analysis. This device has the advantages of simple structure, easy operation, strong practicability, high stability, good repeatability, etc., and can effectively improve the accuracy and efficiency of material property testing.

[0028] The technical features of the above - described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above - described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0029] The above - described embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
