The clamping fixed plates 200 are arranged in pairs and are slidably arranged on the fixed base 100, wherein corresponding positioning circular holes 201 are formed in the clamping fixed plates 200; the locking members 300 are arranged on the clamping fixed plates 200 and are used to limit the sliding of the clamping fixed plates 200.

[0039] When the fracture impact test of the rod-shaped sample is performed, the fracture centering support device provided by the embodiment of the present disclosure is used to adjust the distance between the clamping fixed plates 200 based on the length of the rod-shaped sample, then the two ends of the rod-shaped sample are placed into the positioning circular holes 201, the clamping fixed plates 200 are moved again to clamp and fix the rod-shaped sample, then the sliding of the clamping fixed plates 200 is limited by the locking members 300, finally the fixed base 100 is placed below the hammer of the falling weight impact testing machine, the hammer is placed between the clamping fixed plates 200, and the falling weight is dropped to break the sample placed on the support frame, so that the overall structure of the fracture centering support device is more flexible, the test requirements of samples with different lengths can be met by adjusting the distance, the applicability is improved, and the clamping and fixing of the sample with the curved ends can be more stable, which effectively avoids the displacement or falling of the sample during the impact test, and ensures the stability and safety of the test.

[0040] Optionally, the fixed base 100 is made of stainless steel and has a rectangular structure. In this way, the fixed base 100 has high strength, avoids damage during the test, prolongs the service life, and reduces the maintenance cost.

[0041] It can be understood that the locking member 300 is a locking bolt, which is a prior art and its specific structure is not described herein.

[0042] Optionally, the clamping fixed plate 200 is connected to the fixed base 100 through a sliding structure 400, and the sliding structure 400 comprises a sliding groove 401, a sliding track 402, and a sliding block 403.

[0044] Optionally, the sliding structure 400 is arranged in pairs, and the pair of sliding structures 400 are arranged in parallel on the opposite sides of the upper side of the fixed base 100. In this way, the sliding of the clamping fixed plate 200 can be more stable, so that the clamping fixed plate 200 always slides in one direction under the action of the sliding structure 400, avoiding the situation that the clamping stability of the sample is affected due to the deviation of the clamping fixed plate 200 during sliding.

[0045] Optionally, each clamping fixed plate 200 is composed of a plurality of plate bodies with different heights which are sequentially stacked to form a stepped structure. In this way, among the pair of clamping fixed plates 200, the corresponding two plate bodies have different spacings, so that by sequentially stacking a plurality of plate bodies with different heights to form a stepped structure, the test requirements of samples with different lengths can be met, and the deficiency of sliding adjustment spacing is made up, that is, when the spacing between the pair of clamping fixed plates 200 after sliding still cannot meet the length requirement of the sample, a pair of relatively close or far plate bodies among the corresponding two plate bodies can be selected for use, further improving the applicability.

[0047] Optionally, the height of the clamping fixed plate 200 in the stepped structure decreases in sequence along its moving direction. In this way, the structure is more rationalized, the spacings between the plurality of plate bodies are different, the sample with different length and size can be subjected to the fracture test, and the influence between the plate bodies is reduced, ensuring the smooth installation of the sample.

[0048] Optionally, the height difference between the two adjacent plate bodies is 30mm. In this way, the height difference between the two adjacent plate bodies is within a reasonable range, which facilitates the positioning of the round hole 201 on the protruding part of the plate body, facilitates the installation and fixation of the sample, and ensures the coordination and neatness of the overall structure, so that the overall structure is more stable.

[0049] Optionally, the relatively lower plate body among the two adjacent plate bodies is provided with the positioning round hole 201. In this way, after the sample is installed on one of the plate bodies, the other plate body which is adjacent to the one plate body is used for blocking, without the need for installing an auxiliary fixing piece, ensuring the stability of the sample installation, and avoiding the shaking of the sample under the action of force during the test.

[0050] It is worth mentioning that, for the convenience of clamping and installing the sample, the positioning hole 201 on each plate body is located on the upper side of the adjacent and lower plate body, which will not be described here.

[0051] Optionally, the axis of the positioning hole 201 is in line with the center line of the plate body. In this way, the placed sample can be centered, which helps to better adjust the relative position between the sample and the falling hammer, so that they are quickly aligned, so as to more safely and efficiently perform the test.

[0052] Optionally, the length of the positioning hole 201 is greater than or equal to two-thirds of the thickness of the plate body, and less than or equal to the thickness of the plate body.

In this way, the diameter of the positioning hole 201 is within a reasonable range, so that the device does not need to be frequently replaced when performing the fracture impact test on rod-shaped samples of different diameters, meeting the needs of performing the fracture impact test on rod-shaped samples of various diameters, and saving costs while being more convenient to use.

[0054] As shown in Figures 3-4 Optionally, the plate body provided with the positioning hole 201 is provided with a clamping and fixing part 500, and the clamping and fixing part 500 corresponds to the positioning hole 201. In this way, the clamping and fixing part 500 is used to clamp and fix the rod-shaped sample placed in the positioning hole 201, ensuring the stability of the rod-shaped sample placement, avoiding the situation that the rod-shaped sample shakes or shifts under the action of external force and affects the test effect, and ensuring the safety of the test.

[0055] Optionally, the clamping and fixing part 500 is arranged in pairs, and each clamping and fixing part 500 includes a moving block 501 and a clamping plate 502. The moving block 501 is slidably arranged on the plate body, and the clamping plate 502 is connected with the moving block 501, and the clamping plate 502 is in an arc structure, and the arc surface faces the positioning hole 201. In this way, when the rod-shaped sample is inserted into the positioning hole 201, the moving block 501 drives the clamping plate 502 to slide towards the rod-shaped sample, so that the clamping plate 502 is clamped on the side wall of the rod-shaped sample, avoiding the rod-shaped sample from shaking or shifting, ensuring the stability of the rod-shaped sample placement, and the structure is simple, and easy to install and operate.

[0056] As shown in Figures 5-6As shown, the horizontal detector 101 is arranged on the fixing base 100. In this way, the horizontal detector 101 is used to detect the horizontality of the fixing base 100, so that the fixing base 100 is always placed in a horizontal state, avoiding the situation that the impact test effect and stability of the falling hammer on the rod-shaped sample are affected due to the inclined placement of the fixing base 100, and ensuring the safety of the test.

[0057] Optionally, the fixing base 100 is provided with a scale mark 102, and the scale mark 102 corresponds to the sliding direction of the clamping fixing plate 200. In this way, by arranging the scale mark 102, the sliding length of the clamping fixing plate 200 can be accurately controlled based on the length of the rod-shaped sample, so that the installation and fixation of the rod-shaped sample can be more efficiently and quickly completed without repeated sliding adjustment, and the work efficiency is improved.

[0058] Optionally, the fixing base 100 is provided with a fastening bolt or an adsorption disc. In this way, the fixing base 100 can be fixed to avoid displacement or shaking of the fixing base 100, and the stability of the placement of the fixing base 100 is improved.
