Description

Technical Field

[0001] The invention relates to the technical field of hardness measurement, in particular to a self-cutting building material hardness detection and measurement system. Background Art

[0002] As the foundation of construction projects, the quality of building materials is directly related to the safety and service life of buildings. Hardness is an important indicator to measure the material's ability to resist deformation due to local pressure. Hardness testing can be used to evaluate the physical properties of building materials to ensure that they meet the design requirements and use environment, which helps prevent building structure damage or safety accidents caused by material quality problems.

[0003] When testing the hardness of building materials, the volume of the materials is generally large, which may affect the results of the hardness test. Therefore, in order to obtain more accurate and representative hardness data, it is usually necessary to cut the materials so as to obtain samples of appropriate size for testing. However, the current equipment has the following disadvantages when cutting building materials: when cutting building materials, the friction between the blade and the material will generate a lot of heat, and most of the existing cutting equipment lacks an effective cooling device. The saw blade may fail due to overheating, which is specifically manifested in the reduction of saw blade cutting force and poor cutting surface quality. This not only affects the cutting efficiency, but may also have an adverse effect on subsequent hardness testing. In addition, after a long period of cutting, the sharpness of the blade will decrease. Once the sharpness of the saw blade decreases, it cannot be replaced and repaired in time, and it will vibrate when cutting. Since the sharpness of the blade will decrease after a long period of cutting, and the vibration may be generated during the cutting process, this will not only lead to inaccurate size of the cut sample, but also may affect the internal structure of the sample, thereby misleading the hardness test results.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiment 1, refer to Figure 1-Figure 3A self-cutting building material hardness detection and metering system comprises a base plate 1, a mounting frame 2, a transfer manipulator 3 and a hardness detector 4 are installed on the base plate 1, a lifting rod 41 is arranged on the hardness detector 4, a detection platform 42 is installed at the end of the lifting rod 41, the lifting rod 41 can adjust the height of the detection platform 42 to adapt to building materials of different sizes, a detection head is installed on the hardness detector 4 corresponding to the detection platform 42, which is used to perform hardness detection on the building materials, a cutting platform 21 and a supporting frame 22 are installed on the mounting frame 2, a positioning device is provided on the cutting platform 21, the positioning device is used to position the building materials to be cut, the cutting platform 21 is used to place the building materials to be cut, a cylinder 23 is installed on the top of the supporting frame 22, a mounting seat 24 is installed at the output end of the cylinder 23, a swing arm 25 is rotatably connected to the mounting seat 24, and an adjustment device for controlling the rotation of the swing arm 25 is arranged between the swing arm 25 and the mounting seat 24. The motor 5 is fixedly mounted on the end of the swing arm 25, and a shielding cover 6 is installed on the side of the swing arm 25 away from the motor 5. The shielding cover 6 is used to shield the splashes and dust during the cutting process to protect the safety of the operator. The output shaft of the motor 5 is sequentially installed with a connecting plate 52, a cutting knife 51 and a limiting plate 8 from left to right. The swing arm 25 is rotatably connected to the mounting seat 24 through an adjusting mechanism 26, and is used to carry the motor 5 and the cutting knife 51, and allow them to swing within a certain range to complete the cutting operation. The connecting plate 52 is rotatably connected to the shielding cover 6, and the motor 5 provides power to the cutting knife 51 so that it can rotate and cut the building materials. A positioning plate 61 is installed on the side wall of the shielding cover 6, and the output shaft of the motor 5 is rotatably connected to the positioning plate 61. The transfer manipulator 3 is used to transfer the cut building materials from the cutting platform 21 to the detection platform 42 to realize automatic transfer and reduce manual operation. It also includes: Cleaning assembly: The cleaning assembly is arranged on the positioning plate 61. When the cutting blade 51 rotates to cut the building material, the cleaning assembly can clean the cutting surface of the cutting blade 51 to prevent the debris and dust generated during the cutting process from affecting the cutting effect and the life of the cutting blade 51; Locking assembly: The locking assembly is arranged on the positioning plate 61 and the limiting plate 8. When the cutting knife 51 is not sharp and vibrates, the locking assembly will automatically lock the cutting knife 51 to prevent it from continuing to work and possibly causing damage or safety accidents; Spray assembly: The spray assembly is arranged on the limit plate 8. When the cutting blade 51 rotates to cut the building materials, the spray assembly will spray water to cool down and reduce dust. This can not only protect the cutting blade 51 and the building materials from high temperature damage, but also reduce the impact of dust on the operating environment and operators.

[0023] Furthermore, the cleaning assembly includes a wiping block 62 , the cross section of the wiping block 62 is U-shaped, and the wiping block 62 is fixedly mounted on the positioning plate 61 .

[0024] It should be noted that matching mounting holes are provided on the positioning plate 61 and the wiping block 62, which makes the installation and removal process of the wiping block 62 simpler and faster. The user only needs to align the wiping block 62 with the mounting hole and fix it with a suitable fastener (such as a screw). The inner wall of the wiping block 62 fits the cutting surface of the cutting knife 51 to ensure the cleaning effect. During the cutting process, as the cutting knife 51 rotates, the wiping block 62 can continuously and effectively remove the debris and dust attached to the cutting surface, avoiding the situation where the cutting accuracy is affected by a large amount of impurities attached to the cutting knife 51. Now, the wiping block 62 is detachable, which is convenient for users to maintain and replace. When the wiping block 62 is worn or dirty due to long-term use, the user can easily remove it, clean it or replace it with a new wiping block 62, thereby ensuring the continuous and effective operation of the cleaning component. Since the wiping block 62 is detachable, the user can choose wiping blocks 62 of different materials or specifications according to actual needs. For example, for certain special types of building materials or cutting conditions, it may be necessary to use wiping blocks 62 with higher wear resistance or softer materials to ensure the best cleaning effect.

[0025] In this embodiment, the user first places the building material to be inspected on the cutting platform 21. The cutting platform 21 is designed with a positioning device (not clearly shown in the figure, but can be understood as a necessary component) to ensure that the building material remains in a fixed position during the cutting process to avoid movement or deviation. After starting the system, the cylinder 23 pushes the mounting seat 24 and the swing arm 25 thereon to move toward the building material. The swing arm 25 adjusts its angle through the adjustment mechanism 26 to ensure that the cutting knife 51 can contact and cut the building material at the optimal angle. The motor 5 is started to drive the cutting knife 51 to rotate. During the cutting process, the shielding cover 6 effectively blocks the flying debris and dust to protect the safety of the operator. At the same time, the wiping block 62 on the positioning plate 61 can continuously clean the cutting surface of the cutting knife 51 to maintain cutting efficiency.

[0026] After the cutting is completed, the cylinder 23 will retract, so that the swing arm 25 and the cutting device thereon are away from the building materials. At this time, the transfer robot 3 is started, and the cut building materials are clamped from the cutting platform 21 and transferred to the testing platform 42 through precise robot arm control. The transfer robot 3 places the cut building materials on the testing platform 42. The testing platform 42 adjusts its height through the lifting rod 41 to adapt to building materials of different sizes, ensuring that the detection head can accurately contact the surface of the material. The detection head on the hardness testing machine 4 (which may be a pressure head, a probe or other form of sensor) performs hardness detection on the building material according to preset detection parameters (such as pressure, time, etc.). The detection head may work in a contact or non-contact manner, depending on the design and application requirements of the system. During the detection process, the detection head transmits the collected data (such as indentation depth, rebound speed, etc.) to the system controller for analysis. The system controller calculates the hardness value of the building material based on the collected data and outputs the result on the display screen.

[0027] This system integrates multiple functions such as cutting, transportation and hardness testing, realizing full automation from material preparation to hardness result output, significantly improving work efficiency; the cleaning of the cutting surface of the cutting knife 51 is automatically completed by the wiping block 62, reducing the frequency and difficulty of manual maintenance and improving the stability and reliability of the system.

[0028] Example 2, refer to Figure 3-Figure 5 The locking assembly includes an air cylinder 7 fixedly mounted on the positioning plate 61, an air storage chamber 76 is arranged inside the air cylinder 7, a heat conducting rod 71 and a piston ring 74 are slidably arranged inside the air storage chamber 76, the heat conducting rod 71 is fixedly connected to the piston ring 74, the end of the heat conducting rod 71 passes through the side wall of the air cylinder 7 and extends to the outside of the air cylinder 7, a heat conducting ring 72 is fixedly connected to the heat conducting rod 71 located on the outside of the air cylinder 7, a plurality of balls 73 are rotatably arranged on the heat conducting ring 72, a first spring 75 is fixedly connected to the side wall of the piston ring 74 facing the heat conducting ring 72, the end of the first spring 75 is fixedly connected to the inner wall of the air cylinder 7, and hydrogen is filled between the side wall of the piston ring 74 away from the first spring 75 and the air storage chamber 76.

[0029] Furthermore, the locking assembly also includes a limiting groove 81 provided on the limiting plate 8 . The limiting groove 81 is annularly arranged, and a baffle 82 is fixedly installed in the limiting groove 81 .

[0030] It should be noted that, in the initial state, the end of the heat-conducting rod 71 extends to the inside of the limiting groove 81 and there is a gap between it and the baffle 82. At this time, the baffle 82 rotating with the limiting plate 8 will not contact the heat-conducting rod 71. When the cutting knife 51 rotates normally, there is a gap between the end of the ball 73 and the side wall of the limiting groove 81. At this time, the ball 73 does not contact the limiting groove 81. The ball 73, the heat-conducting ring 72, and the heat-conducting rod 71 are made of high thermal conductivity copper-nickel alloy, which can quickly conduct heat and improve the locking efficiency.

[0031] In this embodiment, in normal state: when the cutting knife 51 rotates normally, there is a gap between the ball 73 and the side wall of the limiting groove 81, and there is no contact and no friction. Therefore, under normal circumstances, it will not affect the rotation and cutting of the cutting knife 51. The end of the heat-conducting rod 71 extends to the inside of the limiting groove 81, but there is a gap between it and the baffle 82, and no locking effect is produced. The hydrogen is in a normal state in the gas storage chamber 76 and does not expand due to heat.

[0032] The ball 73 quickly transfers the heat generated by the vibration to the heat-conducting ring 72 and the heat-conducting rod 71. Since they are made of high thermal conductivity copper-nickel alloy, the heat transfer efficiency is high. The heat is transferred to the hydrogen filled in the air storage chamber 76 through the heat-conducting rod 71. The hydrogen expands due to the heat. The expanded hydrogen pushes the piston ring 74 and the heat-conducting rod 71 to extend outward, compressing the first spring 75. When the heat-conducting rod 71 penetrates into the limiting groove 81 and contacts the baffle 82, a locking effect is generated, and the cutting knife 51 stops rotating.

[0033] When the cutting blade 51 vibrates abnormally, the side wall of the limiting groove 81 will contact the ball 73 and drive the ball 73 to rotate. Since the ball 73, the heat-conducting ring 72 and the heat-conducting rod 71 are all made of a high-thermal-conductivity copper-nickel alloy, this alloy material has excellent thermal conductivity and can quickly and effectively transfer heat. When the ball 73 is subjected to external force, due to the close contact between the ball 73 and the heat-conducting ring 72, the heat generated on its surface can be quickly absorbed by the heat-conducting ring 72 through the alloy material and transferred to the heat-conducting rod 71, this heat will eventually be transferred to the end of the gas storage chamber 76 filled with hydrogen through the heat-conducting rod 71. At this time, the hydrogen will expand due to the heat (because hydrogen is a highly active thermal expansion and contraction gas, when hydrogen undergoes thermal expansion reaction, it has enough power to push the piston ring 74 and the heat-conducting rod 71 to move). The expanded hydrogen pushes the piston ring 74 and the heat-conducting rod 71 to extend outward and compresses the first spring 75. When the heat-conducting rod 71 continues to penetrate into the limiting groove 81 and contacts the baffle 82, the cutting knife 51 can be locked.

[0034] At this time, the cutting blade 51 will stop rotating. At this time, the operator can turn off the motor 5 to stop the cutting blade 51 from rotating. At this time, there will be no contact and friction between the limit groove 81 and the ball 73. At this time, the hydrogen inside the gas storage chamber 76 has no heat conduction and a cold shrinkage reaction will occur. At this time, under the push of the elastic force of the first spring 75, the heat conducting rod 71 will shrink back to its original position and will no longer contact the baffle 82. At this time, when the cutting blade 51 is repaired, the equipment can rotate normally.

[0035] When the cutting knife 51 vibrates abnormally during the cutting process, such vibration is usually caused by a blunt blade. If the cutting is not stopped in time, the cutting knife 51 may become stuck, which will not only cause the cut sample size to be inaccurate, but may also affect the internal structure of the sample, thereby misleading the hardness test result. The design of the locking component is precisely to solve this problem. When vibration occurs, the ball 73 contacts the side wall of the limit groove 81 and generates friction. The heat generated by this friction is quickly transferred to the heat-conducting ring 72 and the heat-conducting rod 71. As the heat accumulates, the hydrogen in the air storage chamber 76 expands due to the heat, pushing the heat-conducting rod 71 outward and contacting the baffle 82, thereby locking the cutting knife 51. This process is automatic and rapid, and can respond to abnormal vibrations in the first time to protect the safety of equipment and users, while also improving the detection accuracy.

[0036] Example 3, refer to Figure 6-Figure 8 The liquid spraying assembly includes a water storage ring 9 fixedly installed on the outside of the limiting plate 8, and a plurality of nozzles 92 are equidistantly provided on the side wall of the water storage ring 9. A magnetic ring 931 is installed on the inner wall of the water storage ring 9 corresponding to the nozzle 92. A limiting rod 95 and a sliding rod 96 are fixedly installed in the inner cavity of the water storage ring 9. A sliding block 97 is slidably provided on the sliding rod 96. The sliding block 97 is elastically connected to the inner cavity side wall of the water storage ring 9 close to the output shaft of the motor 5 through a third spring 961. Two limiting rings 951 are symmetrically installed on the limiting rod 95, and a connecting rod 94 is rotatably provided between the two limiting rings 951. A magnetic ball 93 is fixedly connected to the end of the connecting rod 94 away from the sliding rod 96. The connecting rod 94 is elastically connected to the inner wall of the water storage ring 9 through a second spring 941, and a protrusion 971 is installed on the side wall of the sliding block 97 facing the connecting rod 94.

[0037] Furthermore, the end of the nozzle 92 passes through the side wall of the water storage ring 9 for performing a water spraying operation. The third spring 961 is slidably sleeved on the outside of the slide rod 96. The side wall of the slider 97 and the side wall of the protrusion 971 are both against the inner wall of the water storage ring 9, limiting the movement trajectory of the slider 97. The slider 97 is on the inner side of the connecting rod 94. When the cutting knife 51 rotates, under the action of centrifugal force, the slider 97 will slide outward along the slide rod 96. At this time, the protrusion 971 will come into contact with the connecting rod 94, and the connecting rod 94 will rotate around the limit rod 95 and squeeze the second spring 941. Correspondingly, the magnetic ball 93 will also detach from the magnetic ring 931 to open the corresponding nozzle 92 to spray water all around. At this time, the water sprayed upward will be blocked by the shielding cover 6, and finally fall on the cutting knife 51 to cool down the cutting knife 51, thereby ensuring the cutting effect of the cutting knife 51. The third spring 961 is sleeved on the outside of the slide rod 96.

[0038] A water replenishment port 91 is provided through the side wall of the water storage ring 9 facing the positioning plate 61 for replenishing water into the water storage ring 9. A plug 911 is inserted into the water replenishment port 91 for sealing the water replenishment port 91 to prevent water loss. A groove matching the rotation trajectory of the plug 91 is provided on the positioning plate 61 to avoid interference between the plug 911 and the positioning plate 61 when the water storage ring 9 rotates.

[0039] It should be noted that the corresponding magnetic ball 93 has opposite magnetic poles to the magnetic ring 931, and the nozzle 92 in the initial state is completely blocked by the magnetic ball 93. Under the action of the magnetic force and the second spring 941, the magnetic ball 93 will automatically block the nozzle 92. The protrusion 971 in the initial state does not contact the connecting rod 94. When the cutting knife 51 is not working or the rotation speed is slow, the protrusion 971 at this time does not contact the connecting rod 94, and the solid nozzle 92 is also in a closed state.

[0040] In this embodiment, in the initial state: the water storage ring 9 is fixedly installed on the outer side of the limit plate 8, and a certain amount of water is stored inside. The nozzles 92 are evenly distributed on the side walls of the water storage ring 9. In the initial state, each nozzle 92 is completely blocked by the corresponding magnetic ball 93 adsorbed on the magnetic ring 931 by magnetic force, and the slider 97 is maintained in a position close to the inner side of the slide rod 96 by the elastic force of the third spring 961. At this time, the protrusion 971 does not contact the connecting rod 94, and the connecting rod 94 is maintained in a relatively fixed position by the elastic force of the second spring 941. Therefore, the magnetic ball 93 is also maintained in the state of blocking the nozzle 92.

[0041] The cutting knife 51 starts to work: when the cutting knife 51 starts to rotate, due to the action of centrifugal force, the slider 97 will slide outward along the slide rod 96 (stretching the third spring 961). As the slider 97 slides, the protrusion 971 gradually approaches and finally comes into contact with the connecting rod 94. The contact between the protrusion 971 and the connecting rod 94 causes the connecting rod 94 to rotate around the limit rod 95, while squeezing the second spring 941. The rotation of the connecting rod 94 overcomes the magnetic force between the magnetic ball 93 and the magnetic ring 931, so the magnetic ball 93 is separated from the magnetic ring 931, and the corresponding nozzle 92 is opened.

[0042] It should be noted that due to the different hardness of building materials, the cutting power of the cutting knife 51 is also different. Therefore, when the motor 5 increases the speed and power of cutting, the centrifugal force on the slider 97 is also greater, and the protrusion 971 pushes the connecting rod 94 more. Correspondingly, the gap between the magnetic ball 93 and the magnetic ring 931 is also larger, and the amount of water thrown out is also greater. Conversely, the speed of the cutting knife 51 is slower, and the centrifugal force on the slider 97 is also smaller. At this time, the gap between the magnetic ball 93 and the magnetic ring 931 is also smaller, and the amount of water thrown out is also smaller. In this way, the water storage ring 9 will control the amount of cooling water thrown out according to the cutting power of the cutting knife 51, ensuring that the cutting knife 51 can be fully cooled while saving water during cutting.

[0043] Water spray cooling: When the nozzle 92 is opened, the water in the water storage ring 9 is sprayed out to the surroundings through the nozzle 92 to reduce dust and cool down. At this time, the water sprayed upward will be blocked by the shielding cover 6, and finally fall on the cutting knife 51 to cool down the cutting knife 51, ensuring that the cutting knife 51 can maintain a sharp cutting effect.

[0044] The cutting knife 51 stops working: When the cutting knife 51 stops working or the rotation speed is reduced to a certain level, the slider 97 returns to its initial position under the elastic force of the third spring 961, the contact between the protrusion 971 and the connecting rod 94 is released, and the connecting rod 94 returns to its initial position under the elastic force of the second spring 941. The magnetic ball 93 is re-adsorbed on the magnetic ring 931 under the action of the magnetic force, and the nozzle 92 is blocked again.

[0045] Water replenishment operation: When the water content in the water storage ring 9 decreases, the water replenishment port 91 can be opened by pulling out the plug 911, and water can be replenished into the water storage ring 9 through the water replenishment port 91. After completion, the plug 911 can be reinserted for sealing.

[0046] Through this design, the spray assembly can automatically adjust the water spraying amount according to the rotation speed of the cutting knife 51. When the rotation speed increases, the slider 97 slides outward under the action of centrifugal force, pushing the connecting rod 94 to increase the gap between the magnetic ball 93 and the magnetic ring 931, and the water spraying amount increases accordingly; when the rotation speed decreases, the water spraying amount decreases. This design not only ensures that the cutting knife 51 can be fully cooled during high-power cutting, but also avoids the waste of water resources when the power is low or the work is stopped; by accurately controlling the water spraying amount, not only the cooling effect of the cutting knife 51 is ensured, the service life of the cutting knife 51 is extended, but also energy saving is achieved; at the same time, the design of the shielding cover 6 enables the water sprayed upward to be guided to the cutting knife 51, further improving the cooling efficiency; the sprayed water is not only used for cooling, but also can effectively reduce the dust generated during the cutting process of building materials, improve the working environment, and protect the health of operators.
