This device, through the setting of a return spring and a driving spring, enables the driving mechanism to drive the clamping mechanism to perform a clamping function, and when the driving mechanism is removed, the clamping mechanism can automatically reset, thus eliminating the need for manual clamping and manual reset, saving manpower, and making operation simple and convenient."

[0004] In the aforementioned patent, when testing the performance of building materials, it can only perform compression testing on the building materials in the vertical direction.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0026] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] Reference Figures 1 to 4 This application provides an adjustable building material compressive strength testing machine, including a workbench 1, a fixing component 2 on the outer side of the workbench 1, and a testing component 3 on the top of the workbench 1. The fixing component 2 includes a fixing plate 21, which is slidably connected to the top of the workbench 1. A building material plate 4 is disposed between the two fixing plates 21. The testing component 3 includes a bracket 36, a support plate 37 is fixedly installed on the top of the bracket 36, an adjusting rod 35 is rotatably connected inside the support plate 37, an adjusting block 34 is fixedly installed on the front of the adjusting rod 35, a hydraulic rod 32 is fixedly installed inside the adjusting block 34, a pressure sensor 33 is fixedly installed at the bottom of the hydraulic rod 32, and a testing head 31 is fixedly installed at the bottom of the pressure sensor 33. The testing head 31 is located above the building material plate 4.

[0028] Two side plates 39 are fixedly mounted on the top of the bracket 36, and a worm gear 310 is rotatably connected between the two side plates 39. A worm wheel 38 is fixedly mounted on the back of the adjusting rod 35, and the worm wheel 38 meshes with the worm gear 310. A motor 311 is fixedly mounted on the outer end of the side plate 39, and the output end of the motor 311 moves through the interior of the side plate 39 and is fixedly connected to the worm gear 310. A support rod 313 is fixedly mounted on the top of the bracket 36, and an angle sensor 312 is fixedly mounted on the top of the support rod 313. The detection shaft of the angle sensor 312 is fixedly mounted on the back of the worm wheel 38.

[0029] A control and data processing module 5 is fixedly installed on the bottom front of the workbench 1. The control and data processing module 5 is electrically connected to the hydraulic rod 32, the pressure sensor 33, the motor 311, and the angle sensor 312. The control and data processing module 5 includes a main control chip, a data acquisition module, a drive control module, and a storage module. The data acquisition module is electrically connected to the pressure sensor 33 and the angle sensor 312 to acquire the pressure data of the building material board 4 detected by the pressure sensor 33 and the rotation angle data of the worm gear 38 detected by the angle sensor 312, and transmits the data to the main control chip. The drive control module is electrically connected to the hydraulic rod 32 and the motor 311 to receive control commands from the main control chip and drive the hydraulic rod 32 to extend and retract and the motor 311 to rotate. The storage module is used to store the data processed by the main control chip. The main control chip is used to analyze and process the acquired data and send control commands to the drive control module based on the analysis results.

[0030] In this embodiment, the motor 311 is started, which drives the worm gear 310 to rotate. Through the meshing transmission between the worm wheel 38 and the worm gear 310, the adjusting rod 35 rotates. When the adjusting rod 35 rotates, it drives the hydraulic rod 32, the pressure sensor 33, and the detection head 31 to rotate around the support plate 37, thereby adjusting the angle of the detection head 31. At the same time, the adjusting block 34 is rotated, which drives the adjusting rod 35 to rotate, so that the adjusting rod 35 moves up and down within the support plate 37, thereby adjusting the height position of the detection head 31 and ensuring that the detection head 31 is at a suitable detection distance from the building material board 4. The angle sensor 312 detects the rotation angle of the worm wheel 38 in real time and transmits the data to the control and data processing module 5.

[0031] Once the detection head 31 is adjusted to the appropriate angle and position, the main control chip in the control and data processing module 5 sends a command to the drive control module to drive the hydraulic rod 32 to extend and retract downwards, so that the detection head 31 applies pressure to the building material board 4. The pressure sensor 33 detects the pressure on the building material board 4 in real time and transmits the pressure data to the data acquisition module in the control and data processing module 5. The data acquisition module then transmits the data to the main control chip. The main control chip analyzes and processes the acquired pressure and angle data and judges the compressive strength performance of the building material board 4 according to the preset algorithm and standard.

[0032] After the main control chip analyzes and processes the collected data, it sends the processing results to the storage module for storage so that they can be queried and analyzed later. At the same time, the main control chip can also send instructions to the drive control module based on the analysis results to adjust the extension speed and pressure of the hydraulic rod 32, or control the operation of the motor 311, so as to realize the automation and intelligent control of the detection process.

[0033] Reference Figures 1 to 4In one aspect of this embodiment, the workbench 1 has two sliding grooves 22 inside, and a slider 23 is slidably connected inside each of the two sliding grooves 22. A fixing plate 21 is fixedly installed on the top of the corresponding slider 23. A sliding rod 24 is fixedly installed inside the sliding groove 22, and the slider 23 is slidably connected to the outside of the corresponding sliding rod 24. A screw 26 is rotatably connected to the bottom of the workbench 1 between the two sliding grooves 22. A moving block 25 is screwed to the outside of the screw 26. A connecting rod 28 is hinged between the moving block 25 and the corresponding slider 23. A knob 27 is fixedly installed at the bottom of the screw 26.

[0034] In this embodiment, the building material board 4 is placed on the workbench 1, and the knob 27 is turned to drive the screw 26 to rotate. Since the screw 26 is screwed to the moving block 25, the moving block 25 will move along the axial direction of the screw 26. The moving block 25 pulls the slider 23 to slide in the slide groove 22 through the connecting rod 28, thereby driving the fixed plate 21 to move, so as to clamp and fix the building material board 4 of different sizes. During this process, the slider 23 slides on the slide rod 24 to ensure the stability of the movement.

[0035] In the adjustable building material compressive strength testing machine, the Spartacus SBT710 spoke-type load cell is responsible for accurately detecting the pressure exerted on the building material board 4. Its wide range and high precision characteristics can adapt to various building material tests. The FSG5710Z02-275.015PK1023d-MU / i precision rotation angle sensor 312 monitors the rotation angle of the worm gear 38 in real time, providing data for the angle adjustment of the detection head 31. The signals output by both are received and converted into digital signals by the Advantech ADAM-4017+ data acquisition module and transmitted to the STM32H7 series main control chip. After the main control chip analyzes and processes the data, it uses the drive control module to achieve precise control of various components of the testing machine: the Panasonic A6 series servo driver controls the motor 311 to operate according to the instructions and adjusts the angle of the detection head 31; the Rexroth proportional valve driver precisely adjusts the extension speed and pressure of the hydraulic rod 32. Finally, the processed data is stored by the Samsung 870EVO series solid-state drive for subsequent query and analysis. All components work closely together, from data acquisition and processing to equipment control and data storage, to ensure the testing machine can perform multi-angle, high-precision compressive strength testing of building materials.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] Working principle: Place the building material board 4 on the workbench 1, turn the knob 27 to drive the screw 26 to rotate. Since the screw 26 is screwed to the moving block 25, the moving block 25 will move along the axial direction of the screw 26. The moving block 25 pulls the slider 23 to slide in the slide groove 22 through the connecting rod 28, thereby driving the fixed plate 21 to move, so as to clamp and fix the building material board 4 of different sizes. During this process, the slider 23 slides on the slide rod 24 to ensure the stability of the movement.

[0038] The motor 311 is started, which drives the worm gear 310 to rotate. Through the meshing transmission between the worm wheel 38 and the worm gear 310, the adjusting rod 35 rotates. When the adjusting rod 35 rotates, it drives the hydraulic rod 32, the pressure sensor 33, and the detection head 31 to rotate around the support plate 37, thereby adjusting the angle of the detection head 31. At the same time, the adjusting block 34 is rotated, which drives the adjusting rod 35 to rotate, so that the adjusting rod 35 moves up and down within the support plate 37, thereby adjusting the height position of the detection head 31 and ensuring that the detection head 31 is at a suitable detection distance from the building material board 4. The angle sensor 312 detects the rotation angle of the worm wheel 38 in real time and transmits the data to the control and data processing module 5.

[0039] Once the detection head 31 is adjusted to the appropriate angle and position, the main control chip in the control and data processing module 5 sends a command to the drive control module to drive the hydraulic rod 32 to extend and retract downwards, so that the detection head 31 applies pressure to the building material board 4. The pressure sensor 33 detects the pressure on the building material board 4 in real time and transmits the pressure data to the data acquisition module in the control and data processing module 5. The data acquisition module then transmits the data to the main control chip. The main control chip analyzes and processes the acquired pressure and angle data and judges the compressive strength performance of the building material board 4 according to the preset algorithm and standard.

[0040] After the main control chip analyzes and processes the collected data, it sends the processing results to the storage module for storage so that they can be queried and analyzed later. At the same time, the main control chip can also send instructions to the drive control module based on the analysis results to adjust the extension speed and pressure of the hydraulic rod 32, or control the operation of the motor 311, so as to realize the automation and intelligent control of the detection process.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
