In addition, when building materials are subjected to flexural tests, debris and flying impurities will be generated due to fracture or breakage, which will cause dust accumulation on the table surface, making it difficult to clean, and posing a threat to the personal safety of operators. To achieve the above purpose, the present utility model provides the following technical solutions: An electric flexural testing machine that is convenient for fixing, including a workbench.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0020] Please refer to Figures 1 to 4 , the present invention provides a technical solution: an electric flexural strength testing machine that is convenient to fix, including a workbench 1. There is a support frame 2 on the top of the workbench 1. An inner wall of the support frame 2 is provided with a placement frame 3. A fixing plate 4 is provided between the support frames 2 directly above the placement frame 3. Clamping mechanisms 5 vertically penetrate through the left and right sides of the top of the fixing plate 4. A sleeve plate 6 is provided inside the fixing plate 4. A displacement sensor 7 vertically penetrates through the inside of the sleeve plate 6. A hydraulic mechanism 8 vertically penetrates through the middle of the top of the support frame 2.
[0021] In this embodiment, as Figure 4 shown, the workbench 1 is composed of a metal partition net 101, a box body 102, and a dust collection drawer 103. Among them, the metal partition net 101 is fitted into the top opening of the box body 102, and the dust collection drawer 103 is slidably connected to the left and right inner walls of the box body 102; it should be noted that when using the electric flexural strength testing machine to conduct a flexural test on building materials, due to the fracture and fragmentation of the building materials, it is inevitable to generate some dust, debris and other sundries. In order to avoid the influence of these sundries on the measurement results, it is usually necessary to clean and sweep the tabletop of the workbench 1 in a timely manner, and its operation process is relatively troublesome. Therefore, in the present invention, the workbench 1 is set as a cleaning mechanism composed of the metal partition net 101, the box body 102, and the dust collection drawer 103. When the operator uses the hydraulic mechanism 8 to conduct a flexural test on the building materials, the dust and debris generated by the building materials during the period will directly pass through the mesh holes of the metal partition net 101 under the action of gravity and fall into the dust collection drawer 103 located directly below it and be collected. After the operator completes the test and obtains the test results, the dust collection drawer 103 can be directly manually pulled to slide it out of the outside of the box body 102, and the dust and debris collected inside the entire dust collection drawer 103 can be centrally cleaned. This cleaning method is more concise and convenient, and at the same time, it will not accumulate sundries on the tabletop of the workbench 1, thus affecting the progress of the experiment.
[0022] In this embodiment, as Figure 3As shown, the clamping mechanism 5 is composed of an electric telescopic rod 501 and a clamping plate 502. The driving end of the electric telescopic rod 501 vertically penetrates through the top of the fixed plate 4 and is screwed to the center of the top of the clamping plate 502. It should be noted that when performing a flexural test on building materials, it is necessary to fix them in a stable position to facilitate the pressure test by the hydraulic mechanism 8. Therefore, in this utility model, a clamping mechanism 5 is designed to clamp and fix the position of the entire building material. The specific operation is as follows: First, place the building material horizontally on the top of the placement frame 3, and then start the electric telescopic rod 501 through an external controller, so that its driving end starts to extend downward and pushes the clamping plate 502 screwed thereto to descend together until the bottom of the clamping plate 502 contacts the upper surface of the building material and fits tightly with it, thereby completing the clamping and fixing of the building material, effectively preventing its position from shifting during the flexural test and thus affecting the final measurement result.
[0023] In this embodiment, as Figure 2 and Figure 3 shown, a powerful suction cup 701 is provided at the bottom end of the displacement sensor 7. It should be noted that a general displacement sensor 7 is usually installed on the surface of the object to be measured by means of screwing or snap connection, etc., which may cause the displacement sensor 7 to damage the structure or surface of the object to be measured. Therefore, in this utility model, an adsorption connection installation method is designed. The specific operation is to set a powerful suction cup 701 at the bottom end of the displacement sensor 7. The powerful suction cup 701 can discharge all the air between it and the object to be measured while applying downward pressure, thereby forming a vacuum adsorption state, and then enabling the displacement sensor 7 to be connected to the object to be measured. The vacuum adsorption connection method has the advantages of simple installation and convenient use, and will not cause any damage to the surface of the object to be measured. When the hydraulic mechanism 8 applies pressure to the object to be measured, the elastic element in the displacement sensor 7 will also undergo corresponding strain. At the same time, multiple displacement sensors 7 can also measure the displacement information of the object in different directions, and then comprehensively process and analyze this information to obtain the bending degree of the object.
[0024] In this embodiment, as Figure 1 and Figure 2As shown in the figure, the hydraulic mechanism 8 is composed of a hydraulic cylinder 801, a pressure sensor 802 and a pressing head 803. The driving end of the hydraulic cylinder 801 vertically penetrates through the middle of the top of the support frame 2. The pressure sensor 802 is sleeved on the outer wall of the driving end of the hydraulic cylinder 801, and the pressing head 803 is arranged at the end of the driving end of the hydraulic cylinder 801. It should be noted that when the hydraulic cylinder 801 is started, its driving end will start to extend downward and push the connected pressing head 803 to move downward together until the bottom end of the pressing head 803 contacts the building material directly below it. At this time, a downward pressure is applied to it to conduct a flexural strength test. During this period, the pressure sensor 802 sleeved on the outer wall of the driving end of the hydraulic cylinder 801 will detect the pressure value output by the hydraulic cylinder 801 at the same time, convert the detected pressure value into an electrical signal and output it, and display it on the display screen of the test instrument through a signal processing and display device. By monitoring the pressure value output by the hydraulic cylinder 801, the pressure sensor 802 can judge mechanical property indexes such as the flexural strength and bending strength of the building material.
[0025] In this embodiment, as Figure 1 and Figure 2 shown, a protective cover 104 is provided on the top of the workbench 1. It should be noted that during the process of conducting a flexural strength test on the building material, the building material will break and shatter during the process of being pressed and deformed downward, so it is easy to splash some sundries and debris outward, which is likely to pose a threat to the personal safety of the operator. Therefore, in this utility model, a protective cover 104 is designed on the top of the workbench 1. The protective cover 104 is in a closed state throughout the process of the flexural strength experiment, which can prevent the debris from breaking and shattering during the experiment from splashing out, effectively preventing the operator from being scratched or cut by the broken debris, and protecting the safety of the experimental personnel and the surrounding environment. The transparent window provided on the protective cover 104 can help the operator clearly observe the test process. When it is necessary to place the building material inside it, only need to open the cover door hinged to the front side of the protective cover 104, and the entire protective cover 104 can be easily changed to an open and closed state to facilitate various operations during the experiment.
[0026] The usage method and advantages of this utility model: For this electric flexural strength testing machine that is convenient to fix, during use, the working process is as follows:
[0027] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, first open the cover door, place the building material on the top of the placement frame 3, and then start the electric telescopic rods 501 on both the left and right sides simultaneously through the external controller to push the clamping plates 502 connected thereto downward to move downward together until the bottom of the clamping plate 502 is closely attached to the top of the building material, thereby clamping and fixing the position of the entire building material. Then, the operator connects the bottom end of the displacement sensor 7 to the surface of the building material through the strong suction cup 701. At the same time, the operator can start the hydraulic cylinder 801, so that the driving end of the hydraulic cylinder 801 extends upward and pushes the pressure head 803 to descend together until the bottom end of the pressure head 803 contacts the upper surface of the building material and applies a downward pressure thereto, thereby performing a flexural strength test. During this process, the pressure sensor 802 can monitor the pressure value applied by the hydraulic cylinder 801 at any time, convert it into an electrical signal, and transmit it to the external controller for analysis and processing. During this process, the displacement sensor 7 undergoes corresponding strain along with the downward-pressed building material and measures the displacement information of the object in different directions. Then, these information are comprehensively processed and analyzed to obtain the ultimate bending degree of the object. The flexural strength of the building material itself can be detected through the pressure value and the ultimate bending degree of the object. During the above test process, the building material will generate a lot of debris due to fracture or breakage and fly outward. Most of these debris will directly fall into the dust collection box 103 through the metal mesh 101 in the workbench 1, and the flying debris can be effectively isolated by the protective cover 104, ensuring the safety of the operator and the surrounding experimental environment.
[0028] The above shows and describes the basic principles, main features and advantages of the present invention. Technical staff in this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
