For example, materials in many engineering structures are often subjected to multiple loads such as tension, compression, bending, and torsion simultaneously. Therefore, a device that can perform these tests at the same time is needed to more accurately simulate actual working conditions and conduct in-depth research on material performance. Utility Model Content

[0013] Beneficial effects:

Detailed Implementation

[0022] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figure 1 As shown, the lower surface of the tension and compression electrical box 1 is symmetrically fixed with fixing plates 22, and the lower surfaces of the two fixing plates 22 and the lower surfaces of the two support frames 12 are fixed with support legs 23.

[0025] By setting up a fixed connection between the support frame 12 and the support leg 23, effective support for the specimen is ensured during the tension, compression, bending and torsion tests, thereby ensuring the reliability and safety of the testing machine under different test modes.

[0026] like Figure 1 and Figure 2As shown, a tension-compression-bending-torsion integrated testing machine is provided, including a tension-compression electrical box 1. Two columns 2 are fixedly connected to the upper surface of the tension-compression electrical box 1. An upper cover plate 3 is fixedly connected to the upper surface of the two columns 2. A fixing plate 4 is fixedly connected to the upper side of the two columns 2. A force sensor 5 is installed on the upper surface of the fixing plate 4. An upper universal hanging platform 6 is installed below the fixing plate 4. A tension fixture 7 is installed below the upper universal hanging platform 6. A cantilever beam bending indenter 8 is installed below the tension fixture 7. A lower universal hanging platform 9 is installed on the upper surface of the tension-compression electrical box 1 and between the two columns 2. A tensile test product 10 is installed above the lower universal hanging platform 9.

[0027] The relevant motors and transmission devices are started by the tension and compression electrical box 1, and the force sensor 5 starts working to measure the force change during the tensile process. The upper universal mounting platform 6 starts to move upward under the drive of the power system and connects to the tensile test product 10 through the tensile fixture 7 to apply tension. During this process, the force sensor 5 measures the magnitude of the tension in real time and feeds the data back to the control system. When the tensile test is completed or the bending test is performed separately, the cantilever beam bending head 8 is moved to a suitable position. The upper universal mounting platform 6 drives the cantilever beam bending head 8 to apply bending force to the specimen under the drive of the power system. During the bending process, the force sensor 5 measures the magnitude of the bending force. The control system controls the test process according to the set bending angle, force value and other parameters, and records the corresponding data, such as the maximum bending force and bending angle.

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, a test platform 11 is set on the upper surface of the tension and compression electrical box 1 and on the left side of the two columns 2. A support frame 12 is symmetrically fixedly connected to the left side of the lower surface of the test platform 11. Two slide rails 13 are symmetrically fixedly connected to the upper surface of the test platform 11. A fixing plate 2 14 is set above the two slide rails 13. A cycloidal pin reducer 15 is fixedly connected to the upper surface of the fixing plate 2 14. A servo motor 16 is set to the left side of the cycloidal pin reducer 15. A vertical plate 17 is set to the right side of the cycloidal pin reducer 15. A torsion chuck 18 is set to the right side of the vertical plate 17. A cantilever beam bending fixing fixture 19 is set to the right side of the vertical plate 17 and above the torsion chuck 18. A vertical plate 20 is fixedly connected to the right side of the upper surface of the test platform 11. A torque sensor 21 is fixedly connected to the left side of the vertical plate 20.

[0029] First, the servo motor 16 is started, and the torsion chuck 18 is driven by the cycloidal pin reducer 15 to apply torque to the specimen. At the same time, the torque sensor 21 measures the torque in real time and feeds the data back to the control system. The control system controls the torsion speed and torque based on the feedback data, and continues to torsion until the preset target torque value is reached or the specimen is damaged by torsion. The data of the entire torsion process is recorded.

[0030] like Figure 1 and Figure 3 As shown, a torsion motor housing 24 is fixedly connected to the lower surface of the test platform 11;

[0031] By using the torsion motor box 24 as the key power source for the torsion test, the torsion test can be carried out according to the preset parameters, meeting the requirements of different materials and specimens for torsion force and torsion speed.

[0032] like Figure 1 and Figure 3 As shown, the right side of the two pillars 2 is connected to a protective door 25 via a hinge;

[0033] During the operation of the testing machine, especially when performing mechanical tests such as tensile and bending, unexpected situations such as specimen breakage and fragmentation may occur. The protective door 25 can effectively block these potential dangers and prevent operators from being injured. At the same time, when the protective door 25 is opened, the testing machine stops working simultaneously, ensuring the intelligence and safety of the device.

[0034] like Figure 1 and Figure 3 As shown, a protective door 31 is slidably connected to the upper surface of the test platform 11 and to the opposite sides of the two slide rails 13.

[0035] During the torsion test, the test piece or tooling may move laterally or parts may fly off due to excessive force. The second protective door 31 can effectively block these potential dangers and prevent them from causing harm to the operators and the surrounding environment. At the same time, when the second protective door 31 slides to the left, the testing machine stops working, further ensuring the safety of the device.

[0036] like Figure 3 and Figure 4As shown, a servo motor 26 is provided on the left side of the test platform 11. A lead screw 27 is fixedly connected to the right end of the output shaft of the servo motor 26. The right end of the lead screw 27 is rotatably connected to the left side of the vertical plate 20 via a rotating shaft. A sliding plate 28 is threadedly connected to the outer wall of the lead screw 27. An adjustment plate 29 is fixedly connected to the lower surface of the fixed plate 24. The left side of the adjustment plate 29 is fixedly connected to the right side of the sliding plate 28. Multiple sliders 30 are symmetrically fixedly connected to the lower surface of the adjustment plate 29. The multiple sliders 30 are slidably connected to the outer walls of the two slide rails 13 respectively.

[0037] The output shaft of the servo motor 26 drives the lead screw 27 to rotate. Since the lead screw 27 is threadedly connected to the sliding plate 28, the rotational motion of the lead screw 27 is converted into the linear motion of the sliding plate 28. As the sliding plate 28 moves, the adjusting plate 29 connected to it also moves. Multiple sliders 30 on the lower surface of the adjusting plate 29 slide on the outer walls of the two slide rails 13, thus ensuring that the movement of the adjusting plate 29 is along a predetermined straight line, with high stability and accuracy. Since the fixed plate 24 is fixedly connected to the adjusting plate 29, when the adjusting plate 29 moves, the cycloidal pin reducer 15, servo motor 16 and other test fixtures on the fixed plate 24 also move to the target position. Thus, during the torsion test, the torsion clamp 18 is moved to the appropriate position according to the length and shape of the specimen, so as to accurately install and fix the specimen.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
