For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0025] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Reference Figures 1 to 4 This application provides a mechanical performance testing device for building materials, including a workbench 1. A fixing component 3 is provided on the top of the workbench 1 for fixing the building material to be tested. A detection component 2 is provided above the workbench 1 for testing the mechanical performance of the building material. A data processing and control component 4 is fixedly installed on the front of the workbench 1. The data processing and control component 4 adopts an existing microcontroller control system, which can receive data from various sensors and control various actuators. The microcontroller control system can adopt an STM32F103ZET6, which has stable performance and can meet the data processing and control requirements of the device.

[0027] The detection component 2 includes a top frame 21. A support frame 25 is fixedly installed on the top of the workbench 1. The top frame 21 is fixedly installed on the top of the support frame 25. Two side plates 26 are fixedly installed on the top of the top frame 21. Rotary rods 27 are rotatably connected to the opposite side of each of the two side plates 26. The rotating rods 27 can rotate flexibly on the side plates 26. A hydraulic rod 22 is fixedly installed between the two rotating rods 27. The hydraulic rod 22 passes through the interior of the top frame 21. A pressure sensor 23 is fixedly installed at the output end of the hydraulic rod 22. The pressure sensor 23 can be a PT124G-111. An extrusion head 24 is fixedly installed at the bottom of the pressure sensor 23. The extrusion head 24 is used to contact the building material and apply pressure. Both the hydraulic rod 22 and the pressure sensor 23 are electrically connected to the data processing and control component 4. The hydraulic rod 22 extends and retracts under the control of the data processing and control component 4. The pressure sensor 23 transmits the detected pressure data to the data processing and control component 4.

[0028] The outer ends of both rotating rods 27 extend through the interior of their respective side plates 26. A self-locking reducer 29 is fixedly installed on the front of the front side plate 26. A servo motor 210 is fixedly installed on the left side of the self-locking reducer 29. The servo motor 210 can be a 130ST-M15015. The output end of the servo motor 210 is fixedly connected to the input end of the self-locking reducer 29. The output end of the self-locking reducer 29 is fixedly connected to the front rotating rod 27. The servo motor 210 is electrically connected to the data processing and control component 4. The servo motor 210 works under the control of the data processing and control component 4. It drives the rotating rod 27 to rotate through the self-locking reducer 29, thereby adjusting the angle of the hydraulic rod 22. The self-locking reducer 29 can prevent the rotating rod 27 from rotating on its own when the servo motor 210 stops working, thus ensuring the stability of the angle of the hydraulic rod 22.

[0029] An angle sensor 28 is fixedly installed on the back of the rear side plate 26. The angle sensor 28 can be model WDD35D4. The end face of the rear rotating rod 27 is fixedly connected to the detection end of the angle sensor 28. The angle sensor 28 is electrically connected to the data processing and control component 4. The angle sensor 28 can detect the rotation angle of the rotating rod 27 and transmit the angle data to the data processing and control component 4 so that the operator can understand the pressure angle of the extrusion head 24.

[0030] The fixing component 3 includes a support plate 31, which is slidably connected to the top of the workbench 1. Fixing blocks 33 are fixedly installed on both the left and right sides of the top of the support plate 31. A first screw 34 is screwed through the inside of the fixing block 33. A clamping plate 32 is rotatably connected to the inner end of the first screw 34. The clamping plate 32 is used to clamp the building materials. A first knob 35 is fixedly installed on the outer end of the first screw 34. Rotating the first knob 35 can drive the first screw 34 to rotate. Since the first screw 34 is screwed to the fixing block 33, the first screw 34 will drive the clamping plate 32 to slide on the support plate 31, thereby clamping or loosening the building materials.

[0031] The clamping plate 32 is slidably connected to the top of the workbench 1 to ensure stable sliding. The thread lead angle of the first screw 34 is less than the equivalent friction angle, which gives the first screw 34 a self-locking function. When the first knob 35 is not turned, the clamping plate 32 will not move on its own, ensuring the stability of fixing the building materials. The outer side of the first screw 34 is coated with protective and lubricating grease. The grease is a grease with strong adhesion, anti-leakage, wear resistance and anti-pollution, such as lithium-based grease, which can reduce the friction between the first screw 34 and the fixing block 33, and at the same time prevent the screw from being corroded and contaminated.

[0032] The workbench 1 has a slide groove 36 inside, and a slider 37 is slidably connected inside the slide groove 36. The slider 37 is fixedly installed at the bottom of the support plate 31. The slider 37 slides in the slide groove 36 to provide guidance for the movement of the support plate 31 and ensure the stability of the movement of the support plate 31.

[0033] Side panels 38 are fixedly installed on the bottom of the workbench 1 and on both sides of the slide groove 36. A second screw 39 is rotatably connected between the two side panels 38. The second screw 39 is screwed through the inside of the slider 37. An adjusting rod 310 is rotatably connected to the outer side of the right side panel 38. A second knob 311 is fixedly installed on the outer end of the adjusting rod 310. The inner end of the adjusting rod 310 moves through the inside of the side panel 38 and is fixedly connected to the second screw 39. Rotating the second knob 311 drives the second screw 39 to rotate through the adjusting rod 310. Since the second screw 39 is screwed to the slider 37, the slider 37 will slide in the slide groove 36, thereby driving the support plate 31 to move and realize the adjustment of the position of the support plate 31.

[0034] The thread lead angle of the second screw 39 is less than the equivalent friction angle, which gives the second screw 39 a self-locking function. When the second knob 311 is not turned, the position of the support plate 31 will not change on its own. The outer side of the second screw 39 is coated with protective and lubricating grease. The grease is a grease with strong adhesion, anti-leakage, wear resistance and anti-pollution, which also plays a role in reducing friction and protection.

[0035] Working principle: In use, first, according to the size of the building material to be tested, rotate the second knob 311, which drives the second screw 39 to rotate through the adjusting rod 310, causing the slider 37 to slide within the groove 36, thereby adjusting the position of the support plate 31 to a suitable testing position. Then, place the building material on the support plate 31, rotate the first knob 35, which drives the first screw 34 to rotate, causing the clamping plate 32 to move inward and clamp the building material in place.

[0036] Next, the servo motor 210 is controlled by the data processing and control component 4. The servo motor 210 drives the rotating rod 27 to rotate through the self-locking reducer 29, adjusting the angle of the hydraulic rod 22. The angle sensor 28 transmits the detected angle data to the data processing and control component 4 in real time. When the hydraulic rod 22 is adjusted to the required angle, the servo motor 210 stops working, and the self-locking reducer 29 locks the rotating rod 27 to keep the angle of the hydraulic rod 22 stable.

[0037] Subsequently, the hydraulic rod 22 is extended by the data processing and control component 4, which drives the extrusion head 24 to move downward and apply pressure to the building material. The pressure sensor 23 transmits the detected pressure data to the data processing and control component 4. The data processing and control component 4 processes and displays the data, and the staff can understand the mechanical properties of the building material at this angle based on the displayed data.

[0038] After the test is completed, control the hydraulic rod 22 to retract, release the pressure of the extrusion head 24 on the building material, and then rotate the first knob 35 in the opposite direction to make the clamp 32 release the building material, and then remove the building material.
