[0005] The purpose of this invention is to provide an electric servo-controlled universal testing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric servo-controlled universal testing machine, comprising a base, an internal pressure testing platform, a support plate on the side of the base, and support frames at both ends of the support plate; a downward push plate on the inner side wall of the support plate, and a first slide rail and a second slide rail arranged from the inside to the outside on the side wall of the support frames; a first protective frame slidingly mounted on the first slide rail, and a second protective frame slidingly mounted on the second slide rail; the second protective frame is fitted over the first protective frame, and the upward sliding stroke of the second protective frame is greater than that of the first protective frame. The sliding stroke is such that both the first anti-slip frame and the second protective frame are equipped with protective plates; a servo controller is provided on the outer wall of the support plate and is electrically connected to the pressure detection table and the downward push plate; both the first slide rail and the second slide rail are three-section pull-out linear slide rails, and both the first slide rail and the second slide rail are made of aluminum alloy; the first protective frame is sleeved on the outside of the base, and the base is fixedly connected to the two support frames; an extension frame is hinged to the upper end of the second protective frame, and an auxiliary baffle is provided inside the extension frame, and a handle is provided on the plate wall of the auxiliary baffle.

[0019] 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.

[0020] Please see Figure 1-3 This utility model provides a technical solution: an electric servo-controlled universal testing machine. Starting with its basic construction, the base 1 serves as the cornerstone of the entire device, its design not only considering stability but also incorporating precise measurement functions. The pressure detection platform 2 embedded inside the base 1 is an indispensable core component during the testing process. Utilizing advanced sensor technology, it can capture and record the pressure changes experienced by the material in real time and accurately, providing valuable experimental data support for researchers.

[0021] The support plate 3 and its two end support frames 4 form the skeleton of the testing machine, providing strong support and stability for the entire device. The ingenious design of the support plate 3 allows the downward pressure push plate 5 to be securely installed on its inner wall, ensuring that pressure is applied evenly and stably to the material being tested. This design not only improves the accuracy of the test but also extends the service life of the equipment.

[0022] Next, let's look at the protective system of the testing machine. The side walls of the support frame 4 are equipped with a first slide rail 6 and a second slide rail 7, designed with practicality and convenience in mind. The first protective frame 8 on the first slide rail 6 and the second protective frame 9 on the second slide rail 7 can be flexibly adjusted in position via a sliding mechanism to accommodate test materials of different sizes and shapes. This double-layer protective design not only effectively prevents debris from flying due to material breakage during testing, but also protects other precision components inside the testing machine from damage.

[0023] Of particular note is that the second protective frame 9 is designed to fit over the first protective frame 8, and its upward sliding travel is greater than that of the first protective frame 8. This design allows the second protective frame 9 to quickly cover and protect the first protective frame 8 and its internal test area when needed, thus providing more comprehensive and reliable protection. Furthermore, both the first and second protective frames 8 are equipped with robust protective plates, further enhancing the protective effect and ensuring the safety of the testing process.

[0024] The design of the second protective frame 9 is ingenious. It is carefully fitted over the first protective frame 8, forming a layered protective structure. This design not only makes clever use of space but also greatly enhances the layering and effectiveness of the protection. Specifically, the upward sliding stroke of the second protective frame 9 is intentionally set higher than that of the first protective frame 8. This means that during the test, even if the first protective frame 8 has reached its sliding limit, the second protective frame 9 can still continue to slide upward, providing additional cushioning and protection for possible accidents.

[0025] This dual-layer protection design ensures effective protection against debris splashing and other potential hazards, even under the harshest testing conditions. Furthermore, both the first protective frame 8 and the second protective frame 9 are equipped with robust and durable protective plates made of high-strength materials, offering excellent impact and abrasion resistance. These plates not only further block debris splashing but also protect other critical components of the testing machine from damage.

[0026] It is worth noting that this double-layer protection design is not merely a simple superposition, but the result of meticulous calculation and optimization. By rationally setting the sliding stroke of the second protective frame 9 and the dimensions and shape of the protective plate, the entire protection system is ensured to maintain a stable and reliable working state under various testing conditions. This design not only enhances the safety of the testing machine but also extends its service life and reduces maintenance costs.

[0027] In summary, the design of the second protective frame 9 and the double-layer protection are major highlights of this electric servo-controlled universal testing machine. Together, they constitute an efficient, reliable, and safe protection system, providing a solid guarantee for the normal operation of the testing machine and the personal safety of the personnel.

[0028] A high-performance servo controller 10 is meticulously installed on the outer wall of the support plate 3. This controller is not only the "brain" of the testing machine but also the core for achieving precise control and measurement. Through a series of complex electrical connections, it is tightly linked to the pressure testing platform 2 and the lower pressure push plate 5, forming a highly integrated and responsive control system. During the test, the servo controller 10 can receive precise data from the pressure testing platform 2 in real time and automatically adjust the application speed and force of the lower pressure push plate 5 according to preset parameters, ensuring the stability and accuracy of the test process.

[0029] To ensure the long-term stable operation of this precision system, the design team focused heavily on structural stability. A robust reinforcing rod 11 was added between the two support frames 4. This reinforcing rod 11 acts as the "backbone" of the testing machine, effectively distributing the enormous pressure generated during testing and improving the overall load-bearing capacity and deformation resistance of the structure. Furthermore, reinforcing ribs 12 were specially added at the connection between the support frames 4 and the reinforcing rod 11. These reinforcing ribs 12 act like steel links, tightly connecting the various components and further enhancing the overall rigidity and stability of the testing machine.

[0030] It is worth mentioning that the servo controller 10 also possesses powerful data processing and analysis capabilities. It can process and analyze the massive amounts of data generated during the experiment in real time, providing researchers with detailed experimental reports and data analysis results. This data not only helps researchers more accurately understand the performance characteristics of the tested materials but also provides strong support for subsequent product design and improvement.

[0031] In summary, the introduction of the servo controller 10 not only significantly improves the control precision and measurement accuracy of the testing machine, but also ensures the stability and safety of the testing process through a series of structural optimizations and innovations. This design undoubtedly injects new vitality and competitiveness into the electric servo-controlled universal testing machine.

[0032] To ensure safety during the test, a baffle 13 is designed on the upper side of the inner wall of the support frame 4 to safely block the upward travel of the first protective frame 8 and the second protective frame 9, preventing debris from flying due to material breakage during the test. Furthermore, both the first slide rail 6 and the second slide rail 7 adopt a three-section pull-out linear slide rail design, and both slide rails are made of aluminum alloy to ensure smooth sliding and good durability.

[0033] To further enhance the safety of the testing machine, the first protective frame 8 is designed to be fitted over the base 1, and the base 1 is fixedly connected to both support frames 4, ensuring the stability of the overall structure. An extension frame 14 is hinged to the upper end of the second protective frame 9. The extension frame 14 has an auxiliary baffle inside to further block debris. Handles are also provided on the walls of the auxiliary baffle for easy adjustment and operation by the operator.

[0034] This double-layer protective design, consisting of a first protective frame 8 and a second protective frame 9, with the second protective frame 9 having a higher sliding stroke than the first protective frame 8, effectively prevents debris from flying due to material breakage during the test. This double-layer protective design not only greatly reduces the risk of injury to surrounding equipment and personnel but also significantly improves the safety of the entire testing process.

[0035] Working principle: When this utility model is working, the base 1 serves as the supporting foundation for the whole machine, and the pressure detection platform 2 is installed inside to accurately measure the pressure value generated during the test.

[0036] The support plate 3 is laterally fixed to the base 1, providing a stable support structure. Support frames 4 are provided at both ends of the support plate 3 to further enhance the stability of the overall structure.

[0037] The first protective frame 8 and the second protective frame 9 are slidably mounted on the support frame 4 via the first slide rail 6 and the second slide rail 7, respectively, forming a double-layer protective structure. This design aims to prevent debris from flying due to material breakage during the test, ensuring the safety of surrounding equipment and personnel.

[0038] The protective plates on the first protective frame 8 and the second protective frame 9, together with the baffle 13 on the inner side of the support frame 4, constitute a safety barrier, effectively limiting the spread of the splashing material.

[0039] The servo controller 10, as the core control unit, is electrically connected to the pressure testing platform 2 and the lower pressure push plate 5 to achieve precise control of the test process. According to the preset test parameters (such as loading speed, maximum load, etc.), the servo controller 10 can automatically adjust the motion state of the lower pressure push plate 5 to simulate the mechanical loading conditions under actual working conditions.

[0040] Before the test begins, the material to be tested is placed on the pressure testing platform 2, and the test parameters are set through the servo controller 10.

[0041] During the experiment, the servo controller 10 drives the pressure pusher 5 to load the material according to preset parameters. At the same time, the pressure detection platform 2 measures and records the pressure value during the loading process in real time.

[0042] If the material breaks or fractures during the test, the resulting debris will be effectively blocked by the first protective frame 8 and the second protective frame 9, preventing it from splashing into the surrounding area.

[0043] The reinforcing rod 11 and the reinforcing rib 12 enhance the load-bearing capacity and stability of the support frame 4, preventing deformation or damage due to excessive force during the test.

[0044] The baffle 13 is designed to safely block the upward sliding stroke of the first protective frame 8 and the second protective frame 9, preventing them from detaching from the support frame 4 due to excessive upward movement or causing other safety hazards.

[0045] In summary, this electric servo-controlled universal testing machine, through a combination of precise structural design and advanced servo control technology, achieves efficient and accurate testing of the mechanical properties of materials, and effectively ensures the safety of the testing process.
