Description

Technical Field

[0001] This utility model relates to the field of engineering testing technology, and in particular to an adjustable loading angle testing device for the shear strength of engineering materials. Background Technology

[0002] In the fields of engineering construction and materials research and development, the shear strength of engineering materials is a key indicator for evaluating their mechanical properties. Different engineering scenarios have different requirements for the stress angle of materials, all of which require materials to have good shear performance at specific angles. However, the test device can only conduct loading tests at fixed angles and cannot simulate the situation of materials under complex actual stress states. This leads to deviations between the test results and actual engineering needs, making it difficult to comprehensively and accurately reflect the true shear performance of materials. Therefore, developing an engineering material shear strength test device with an adjustable loading angle is of great significance for improving the accuracy of material performance evaluation and promoting the rational application of engineering materials.

[0003] In shear strength testing, shear force is applied to the material through an output component. When the material fails, its shear performance can be measured. However, the loading angle is fixed and the direction of the loading force cannot be precisely controlled, resulting in test results that cannot accurately simulate the actual stress conditions in engineering. To solve these problems, existing equipment adopts a modular structure, which adjusts the loading angle by changing the clamps at different angles to conduct shear tests at different angles. However, these devices have many drawbacks. The modular clamp replacement process is cumbersome, increasing the time and labor costs of the test operation. The lack of adjustment function leads to insufficient work efficiency and convenience, making it difficult to meet the usage requirements. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an engineering material shear strength testing device with an adjustable loading angle, aiming to improve the problems of cumbersome operation and insufficient adjustability in the existing technology, which leads to reduced work efficiency and test results.

To further enhance the flexibility of adjustment, multiple adjusting holes 9 are provided on the adjusting plate 4. These holes can be used with the positioning pins on the positioning frame 10 to achieve more precise positioning. The positioning frame 10 is equipped with a spring 11, which can automatically reset and lock after positioning, thereby ensuring the stability and reliability of positioning. The testing mechanism 2 is used to conduct shear strength tests. It can simulate the shear force in the actual working environment to test the shear performance of the material.

[0033] Please see the appendix Figure 1 and attached Figure 4 The test mechanism 2 includes a fixed rod 201. The bottom end of the fixed rod 201 is fixedly connected to the front left side of the top of the support platform 1. A connecting frame 202 is fixedly connected to the top of the fixed rod 201. A sliding plate 203 is slidably connected to the outer wall of the fixed rod 201. A shearing block 204 is fixedly connected to the bottom of the sliding plate 203. A servo motor 205 is fixedly connected to the right side of the inner wall of the support platform 1. A screw 206 is fixedly connected to the output end of the servo motor 205.

[0034] Specifically, the fixed rod 201 is securely connected to the support platform 1, ensuring the stability of the entire mechanism. The connecting frame 202 securely connects the fixed rod 201, making subsequent tests more stable. The slide plate 203 moves freely on the fixed rod 201, providing flexible operating space for the test mechanism 2. The presence of the shearing block 204 enables the test mechanism 2 to perform precise shearing operations, ensuring that the test can proceed smoothly. The servo motor 205, in conjunction with the screw 206, enables the shearing action during the test to be automatically executed and adjusted.

[0035] Please see the appendix Figure 1 and attached Figure 5 The bottom of the support platform 1 is fixedly connected to a support plate 12. Multiple support feet 13 are fixedly connected to the left and right sides of the bottom of the support plate 12. A card slot 14 is opened on the right side of the front of the support platform 1. A nameplate 15 is fixedly connected to the inner wall of the card slot 14. Multiple decorative strips 16 are fixedly connected to the left and right sides of the support platform 1. The multiple decorative strips 16 are arranged symmetrically among each other.

[0036] Specifically, the support platform 1 is connected to the support plate 12, ensuring the stability of the support platform 1. These support feet 13 not only increase the stability of the support platform 1, but also adapt to the needs of different ground surfaces, ensuring the stability of the support platform 1.

The decorative strips 16 are for aesthetics and decoration. These decorative strips 16 not only enhance the overall appearance of the support platform 1, but they are also arranged symmetrically, making the whole device look more beautiful.

[0037] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5 A reinforcing ring 17 is fixedly connected to the bottom of the outer wall of the fixing rod 201. Multiple reinforcing blocks 18 are fixedly connected to the bottom of the front side of the fixing plate 3. Multiple anti-slip strips 19 are fixedly connected to the inner wall of the clamping block 6. The multiple anti-slip strips 19 are arranged at equal intervals. A handle 20 is fixedly connected to the left end of the bidirectional threaded rod 8. A rubber sleeve 21 is fixedly connected to the outer wall of the handle 20.

[0038] Specifically, the reinforcing ring 17 can enhance the structural strength of the fixing rod 201, making it less prone to deformation and damage when subjected to greater pressure and impact. The addition of these reinforcing blocks 18 further improves the stability and durability of the fixing plate 3. These anti-slip strips 19 are arranged at equal intervals, which can effectively prevent accidents caused by slippage during use. The bidirectional threaded rod 8 can be easily rotated through the throttle 20 to achieve clamping and fixing operations. The throttle 20 is equipped with a rubber sleeve 21, which makes operation more convenient and provides a better grip.

[0039] Working principle: An adjusting plate 4 is rotatably connected to a fixed plate 3 fixed on a support platform 1. A sliding groove 5 is provided on the adjusting plate 4, allowing the clamping block 6 to slide stably with the assistance of a slide 7. When the bidirectional threaded rod 8 is rotated, the clamping block 6, which is threadedly connected to the bidirectional threaded rod 8, moves synchronously to clamp the material. Since multiple adjusting holes 9 are provided on the adjusting plate 4, the adjusting plate 4 can be rotated by pulling out the positioning frame 10, which is locked in the inner wall of the adjusting hole 9, thereby adjusting the set angle. After adjustment, the positioning frame 10 is released and will be locked back in the inner wall of the adjusting hole 9 under the pulling force of the spring 11. This structure is simple, easy to operate, and can adjust multiple angles to cooperate with subsequent shearing tests, improving the accuracy of the experiment and meeting the adjustment requirements.

[0040] A connecting frame 202 is fixed on a fixed rod 201, and a screw 206 is rotatably connected between the support platform 1 and the connecting frame 202. When the servo motor 205 is started, the screw 206 at its output end will rotate, thereby driving the slide plate 203, which is threadedly connected to the outer wall of the screw 206 and slidably connected to the fixed rod 201, to slide up and down. Since the bottom of the slide plate 203 is fixedly connected to the shear block 204, the shear block 204 can move to perform a shear strength test on the fixed material. This structure can shear the material, thereby calculating the shear strength of the material through the material's breaking force, which meets the experimental requirements.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
