[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 The present invention provides the following technical solution: a clamping and stable electronic universal testing machine, including a fixed plate 1, a frame 2 fixedly installed on the top of the fixed plate 1, electric slides 3 fixedly installed on both sides of the inner wall of the frame 2, a first slider 4 slidably connected to the surface of the electric slides 3, a crossbeam 5 fixedly installed on one side of the first slider 4, a guide auxiliary rod 6 fixedly installed on the inner wall of the frame 2, a servo motor 7 fixedly installed on one side of the crossbeam 5, a housing 8 connected to the output end of the servo motor 7, a placement groove 9 opened on one side of the housing 8, a small electric push rod 10 fixedly installed on the surface of the housing 8, and a clamping block 11 fixedly connected to one end of the small electric push rod 10.

[0022] The staff placed both ends of the test material into the placement slots 9 on one side of the housing 8. After placement, the small electric push rod 10 was activated, driving the clamping plates 11 to move. After adjustment, the two clamping blocks 11, in pairs, could press against both sides of the test material, clamping and fixing it with the extrusion force generated by the drive. Simultaneously, the anti-slip protrusions increased the friction between the clamping blocks 11 and the test material, preventing the test material from detaching during the tensile test. The phenomenon, and the conical shape of the placement groove 9, prevents the test material from falling out of the housing 8, ensuring the test effect of the test material and improving the use effect of the electronic universal testing machine. After the test material is fixed, the electric slide table 3 can drive the first slider 4 to move and adjust. The first slider 4 can then drive the crossbeam 5 to move, so that the distance between the two crossbeams 5 can be adjusted to realize the tensile test on the test material. During the movement and adjustment process, the first slider 4 will slide through the guide auxiliary rod 6. The guide auxiliary rod 6 can enhance the stability of the first slider 4 during the movement and adjustment process, ensuring the stability of the first slider. The stability of the servo motor 7 is improved, and after starting, the servo motor 7 can drive the housing 8 to rotate, enabling torsion testing of the test material and improving the testing requirements of the electronic universal testing machine. The operator can pull the PVC transparent plate 15 using the handle 16. The PVC transparent plate 15 will slide on the surface of the guide rail 13 via the second slider 14. After adjustment, the two PVC transparent plates 15 can be combined to shield the front of the frame 2, protecting it from splashing of test material during testing and ensuring the operator's safety. The device is designed to protect the health of the test materials. Staff can observe the test materials inside the frame 2 through the PVC transparent panel 15. The protective baffle 12 on the back of the frame 2 protects the test materials and prevents them from splashing outside the frame 2 after breakage, ensuring the safety of the test area. The rubber pad can reduce the noise of the test materials splashed onto the surface of the protective baffle 12. All electrical equipment in this device is powered by an external power source. The motor, electric push rod, electric slide, etc. of this utility model are all controlled by a PLC automatic control system.

[0023] In one aspect of this embodiment, two housings 8 are used to facilitate clamping and fixing the two ends of the test material for testing the test material.

[0024] In one aspect of this embodiment, the electric slide table 3 can drive the first slider 4 to move and adjust when started. During the movement and adjustment process, the first slider 4 will slide through the guide auxiliary rod 6. The guide auxiliary rod 6 can enhance the stability of the first slider 4 during the movement and adjustment process and ensure the stability of the first slider 4.

[0025] In one aspect of this embodiment, the protective baffle 12 on the back of the frame 2 is used to protect the test material, preventing the test material from splashing outside the frame 2 after it breaks, thus ensuring the safety of the test area. The rubber pad can reduce the noise of the test material splashed onto the surface of the protective baffle 12, preventing the test material from generating noise.

[0026] In one aspect of this embodiment, the clamping block 11 located inside the housing 8 can clamp and fix the test material placed inside the housing 8, thereby improving the stability of the test material during the test. At the same time, the anti-slip protrusion can strengthen the clamping strength of the clamping block 11, increase the friction between the clamping block 11 and the test material, and prevent the test material from falling off during the tensile test.

[0027] In one aspect of this embodiment, the support foot 17 can be installed on the ground through the mounting hole, thereby fixing the testing machine in place, improving the stability and accuracy of the testing machine during use, and preventing the testing machine from moving during use and affecting the accuracy of the test material test.

[0028] In one aspect of this embodiment, the operator can pull the PVC transparent plate 15 using the handle 16. The PVC transparent plate 15 will slide on the surface of the guide rail 13 via the second slider 14. After the two PVC transparent plates 15 are moved and adjusted, they can be merged to shield the front of the frame 2 and protect the front of the frame 2, preventing the test material from splashing and harming the operator during the test, thus protecting the operator's health. The operator can observe the test material being tested inside the frame 2 through the PVC transparent plate 15.
