[0019] Example: Figure 1-4 As shown, this utility model provides a multi-dimensional dynamic loading test device, including an operating table 1. A slide rail 2 is fixedly mounted on the top of the operating table 1. Symmetrically distributed movable frames 21 slide within the slide rail 2. The movable frames 21 are electrically driven by an electric cylinder, causing two movable frames 21 to move in opposite directions outside the slide rail 2. A positioning frame 22 is installed on the opposite side of the two movable frames 21. The positioning frame 22 can clamp and position the rubber material. A threaded rod 23 is threaded into the positioning frame 22. A fixing plate 24 is rotatably mounted at the bottom end of the threaded rod 23. The fixing plate 24 is used to limit the movement of a top plate 25. The top plate 25 is fixedly mounted at the bottom end of the fixing plate 24 and is located near the operating table 1. A sliding clamping plate 26 is installed at one end of the positioning frame 22, and a placement box 27 is installed at the bottom of the inner wall of the positioning frame 22. The clamping plate 26 and the placement box 27 can be replaced according to the shape and specifications of the rubber material, such as ring, sheet or column, so as to better clamp the material. A T-shaped insert 3 is fixed on the opposite side of the clamping plate 26 and the placement box 27. The two T-shaped inserts 3 are respectively movably inserted into the positioning frame 22 and the top plate 25. The top plate 25 and the positioning frame 22 are both equipped with a damping rotating shaft 31 on the outside. A baffle 32 is fixed on the outside of the rotating shaft 31. The two baffles 32 are respectively located on the side of the clamping plate 26 and the placement box 27. The baffles 32 will not rotate when not subjected to external force.

[0020] A support frame 4 is fixedly mounted on the top of the operating table 1. An electric cylinder 41 is fixedly mounted on the top of the support frame 4. The output end of the electric cylinder 41 is inserted through the support frame 4 and a protective frame 42 is fixedly mounted thereon. Therefore, an observation window 43 is installed on the outside of the protective frame 42. Auxiliary rods 44 are symmetrically distributed and fixedly mounted on the top of the protective frame 42. The auxiliary rods 44 are movably inserted into the support frame 4.

[0021] By adopting the above technical solution, the test rubber material can be clamped by the protective frame 42.

[0022] The bottom of the control panel 1 is fixed with support legs 12 arranged in a rectangular array.

[0023] By adopting the above technical solution, the support leg 12 can support the entire device.

[0024] A scale bar 11 is installed at the top of the slide rail 2.

[0025] By adopting the above technical solution, the scale bar 11 can be used to easily mark the positions of the two movable frames 21.

[0026] A turntable 28 is fixedly mounted on the end of the threaded rod 23 away from the fixed plate 24.

[0027] By adopting the above technical solution, the turntable 28 rotates, causing the threaded rod 23 to rotate.

[0028] The positioning frame 22 is mounted on the outside of the movable frame 21 by bolts and nuts.

[0029] By adopting the above technical solution, the positioning frame 22 can be installed and disassembled on the movable frame 21.

[0030] The top plate 25 is mounted on the bottom of the fixed plate 24 by screws.

[0031] By adopting the above technical solution, the top plate 25 can be disassembled and installed on the fixed plate 24.

[0032] A guide rod 33 is fixedly provided on the outer side of the fixed plate 24, and a square groove 34 is provided on the inner wall of the positioning frame 22, in which the guide rod 33 is movably inserted.

[0033] By adopting the above technical solution, the guide rod 33 and the square groove 34 can limit the downward movement of the fixed plate 24.

[0034] Working principle: First, the specifications of the clamping plate 26 and the placement box 27 are changed according to the shape of the rubber material to be tested, so that the clamping plate 26 and the placement box 27 match the shape of the rubber material. At this time, the two baffles 32 are rotated so that the baffles 32 no longer limit the clamping plate 26 and the placement box 27. Then, the clamping plate 26 and the placement box 27 can be disassembled through the T-shaped insert 3. Next, the clamping plate 26 and the placement box 27 that match the rubber material are installed. Finally, the baffles 32 limit the clamping plate 26 and the placement box 27. Then, the two ends of the material are placed inside the two placement boxes 27 respectively. Then, the turntable 28 is rotated so that... The rotation of turntable 28 drives fixed plate 24 to move downward with the assistance of guide rod 33 and square groove 34. The downward movement of fixed plate 24 drives top plate 25 to move downward, and the downward movement of top plate 25 drives clamping plate 26 to move. The clamping plate 26, in conjunction with placement box 27, clamps the sample. Then, the moving frame 21 can move outside of slide rail 2 to perform reciprocating tensile tests on rubber materials. The shape of clamping plate 26 and placement box 27 can be changed according to the shape of the test sample, so that it can be applied to rubber specimens of different shapes and sizes, ensuring tightness without damaging the material, effectively reducing local stress on the specimen, and thus more accurately transferring the load.

[0035] Before the test, start the electric cylinder 41 to make it work. The output end of the electric cylinder 41 drives the protective frame 42 to move downward with the assistance of the auxiliary rod 44. The downward movement of the protective frame 42 protects the rubber material under test and avoids the problem of breakage and debris splashing out, which may cause safety hazards, thereby achieving the purpose of safety protection. At the same time, the test material can be observed in real time through the observation window 43.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
