Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic universal testing machine technology, specifically a protection device for a microcomputer-controlled electronic universal testing machine. Background Technology
[0002] The protective device of a microcomputer-controlled electronic universal testing machine is a component used to ensure the safety of operators and equipment during the testing of material mechanical properties. During the test, the protective device can effectively fix the specimen and prevent it from breaking suddenly due to excessive force, thereby avoiding safety hazards caused by flying fragments.
[0003] Currently, the protective devices of existing electronic universal testing machines have limitations when conducting material testing. During the test, the sample is subjected to strong compression, and most existing protective devices use a single fixing device to fix it in place. This cannot effectively absorb the impact force when the sample breaks, nor can it ensure the stable fixation of the sample during the test. In addition, most existing protective devices use a single protective cover, which cannot effectively cope with the impact force when the sample breaks. Excessive impact force can also affect the protective cover. At the same time, due to unstable sample fixation and vibration interference during the test, the accuracy and stability of the test are also affected.
[0004] Currently, existing protective devices for electronic universal testing machines often subject samples to intense compression during material testing. Most existing devices rely on a single fixing mechanism before the compression test. This simple fixing method is often ineffective in absorbing the enormous impact force generated when the sample breaks, and it cannot ensure the sample's stability during testing. Once the sample breaks during testing, the resulting fragments and impact force can easily damage the equipment. Furthermore, existing protective devices are insufficient in handling the impact force of sample breakage. Most devices use only a single protective cover, which often cannot withstand excessive impact forces and may even be damaged itself. Therefore, this invention provides a protective device for a microcomputer-controlled electronic universal testing machine. Utility Model Content

The protective cover 1 provides overall protection, protecting the internal components of the testing machine and the operator from accidental damage such as sample breakage. The bottom of the inner wall of the protective cover 1 is provided with the fixing plate 2, which serves as the basic support structure inside the testing machine for installing and fixing other components. A mounting block 3 is provided on one side of the top of the fixing plate 2, and an electric push rod 4 is provided on the other side of the top of the fixing plate 2 away from the mounting block 3. The electric push rod 4 provides power to perform a compression test on the sample. The mounting block 3... The buffer seat 5 faces the electric push rod 4. The mounting block 3 is used to install the buffer seat 5 and provide stable support for it. The buffer seat 5 is used to absorb the impact force when the sample breaks and protect the testing machine. The other end of the buffer seat 5 is equipped with a fixing clamp 6. The fixing clamp 6 is used to stabilize and fix one end of the sample to ensure that the sample will not shift or fall off during the test. The side of the electric push rod 4 facing the fixing clamp 6 is equipped with a compression plate 7. The end of the compression plate 7 facing the fixing clamp 6 is equipped with a compression clamp 8. The compression plate 7 is pushed by the electric push rod 4 and together with the compression clamp 8, it performs a compression test on the sample. The compression clamp 8 cooperates with the fixing clamp 6 to clamp and compress the sample.
[0029] In this embodiment, the front and rear sides of the top of the fixed plate 2 are provided with sliding grooves 9 at the connection with the extrusion plate 7. The sliding grooves 9 are used to provide a sliding track for the extrusion plate 7 so that it can move smoothly. The front and rear ends of the bottom of the extrusion plate 7 are slidably connected to the sliding grooves 9. Limiting plates 10 are provided on both sides of the sliding grooves 9. The limiting plates 10 are used to limit the range of movement of the extrusion plate 7 and prevent it from moving excessively.

[0032] It should be noted that when using the protective device of the microcomputer-controlled electronic universal testing machine, firstly, open the sealing door 16 on the protective cover 1 of the testing machine, install the sample to be tested onto the fixed clamp 6, and adjust the locking mechanism 11 of the fixed clamp 6 and the compression clamp 8 as needed to ensure that the sample is firmly clamped. Close the sealing door 16 to ensure that the inside of the protective cover 1 is sealed. According to the specifications and size of the sample, adjust the position of the slide 9 and the limiting plate 10 to limit the movement range of the compression plate 7 and prevent it from moving excessively. Start the microcomputer control system and start the test program. The electric push rod 4 starts to work, pushing the compression plate 7 and the compression clamp 8 to move towards the fixed clamp 6 to perform the compression test on the sample. When the sample breaks or reaches the preset test conditions, the electric push rod 4 stops working, the compression plate 7 and the compression clamp 8 stop moving, open the sealing door 16, remove the broken sample, and clean the debris and residue inside the testing machine.
[0033] Example 2: It also includes a sealing door 16 at the top of the protective cover 1.

[0035] In this embodiment, the bottom of the protective steel plate 17 located at the top is provided with a telescopic column 21, and the bottom of the telescopic column 21 is provided with an arc-shaped cover 22. The telescopic column 21 is used to support the arc-shaped cover 22, so that it can be adjusted according to the height of the sample. The arc-shaped cover 22 is used to provide an additional protective layer to prevent fragments from flying when the sample breaks. The arc-shaped cover 22 is located at the top of the connection between the fixing fixture 6 and the extrusion fixture 8. Multi-stage telescopic rods 23 are provided between the two sides of the arc-shaped cover 22 and the protective steel plate 17. The multi-stage telescopic rods 23 can be used in conjunction with the telescopic column 21 for height adjustment. The multi-stage telescopic rods 23 are used to provide support for the two sides of the arc-shaped cover 22 to ensure the protective effect of the arc-shaped cover 22.
[0036] It should be noted that: throughout the testing process, the protective outer cover 1 and the inner protective steel plate 17 provide safety protection for the operator and prevent fragments from flying when the sample breaks. The arc-shaped cover 22 is located on top of the connection between the fixed clamp 6 and the extrusion clamp 8, providing an additional protective layer to further prevent fragments from flying.
[0037] The beneficial effects of the above embodiments are as follows:
[0038] The protective device of this microcomputer-controlled electronic universal testing machine achieves stable specimen fixation through the design of the buffer seat 5 and the fixed clamp 6 on the mounting block 3, ensuring that the specimen will not shift or fall off due to external forces during the test. On the other side of the specimen, the electric push rod 4 pushes the extrusion plate 7 and the extrusion clamp 8 to extrude the specimen for extrusion testing, thereby achieving effective extrusion of the specimen. At the same time, the design of the buffer spring 14 and the guide rod 15 inside the buffer seat 5 enables the device to quickly absorb and disperse the impact force at the moment of specimen breakage, effectively reducing the risk of fragments flying. In addition, the design of the protective steel plate 17 and the buffer component 18 inside the protective cover 1 further enhances the safety and stability of the entire device. The spring column 19 and the telescopic guide column 20 inside the buffer component 18 work together to provide additional buffering and support during the test, effectively reducing the impact and noise caused by specimen breakage or vibration during the test, and improving the accuracy and stability of the test.
