The combination of the pressing plate and the Velcro layer allows the operator to... Different materials are adhered to the bottom of the pressing plate through a Velcro layer, thereby allowing for various tests on the ceramic fiberboard and improving the accuracy of the device's testing. Patent application number CN202310627042.7 discloses a strength and compressive strength testing device and method for foamed ceramic boards, including a workbench and a testing instrument. A lifting assembly is installed on the top of the workbench, and a support platform is connected to the output end of the lifting assembly. A second drive cylinder is connected to the top of the support platform, and a fixed plate is connected to the output end of the second drive cylinder. The testing instrument is connected to the bottom of the fixed plate, and the fixed plate has various mounting points on both sides. The positioning component that works in conjunction with the measuring instrument includes a clamping component and a protective component on the top of the worktable. The lifting component's output end has a linkage component for fixing the foamed ceramic plate to the clamping component, and the bottom of the clamping component has an adjustment component for vertically moving the protective component. This invention is simple to operate and convenient to use. It can easily fix the foamed ceramic plate to be tested and provide good protection during the testing process, avoiding safety hazards. According to its disclosed technical solution, existing ceramic strength testing equipment often requires applying high pressure to alumina ceramics, which can easily cause significant wear on the pressure-applying equipment, reducing its service life.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. When using this alumina ceramic strength testing device, open the side door, place the alumina ceramic on top of the pad, and then, depending on the height of the alumina ceramic, the motor moves the screw sleeve and pad upwards via the screw rod until the top of the alumina ceramic is locked at the bottom of the pressure rod. The two ends of the pad are supported at the bottom of the chamber by the wedge patterns on the clamping plate. When performing strength testing on the alumina ceramic, simply adjust the position of the counterweight and amplify the pressure through the lever to press the pressure rod downwards, thus effectively performing the strength testing on the alumina ceramic. During the strength testing process, the pad is supported by the wedge patterns on the clamping plate, and the motor, screw rod, and screw sleeve do not need to bear pressure, reducing equipment wear and ensuring the service life of the equipment. At the same time, the use of levers, counterweights, and pressure rods for pressure application results in a simple structure that does not easily cause wear or deformation, thus improving the service life of the equipment.

[0016] 2. When using the alumina ceramic strength testing device, to perform a qualified strength test on the alumina ceramic, open the cover plate. Motor 3 drives the baffle to move via screw 2 until the baffle moves to the corresponding strength position. Then, open motors 4 and 2. Motor 4 pushes the support sleeve downward via screw 2, causing the right end of the lever to lose the support sleeve. Motor 2 pushes the counterweight to the right on the lever via screw 1 until the counterweight presses button 1, at which point motor 2 stops working. This is to test whether the alumina ceramic can withstand the required pressure strength. When performing a maximum strength test on the alumina ceramic, motor 3 pushes the baffle to the far right via screw 2. Then, open motor 2. Motor 2 pushes the counterweight to the right via screw 1. Until the alumina ceramic is damaged, causing the top of the right end of the lever to separate from button two, motor two stops working. The precise strength value can be obtained through the pressure value corresponding to the counterweight and the scale corresponding to the indicator block on lead screw one. When the lever moves slightly and slowly downward due to the pressure of the lever on the alumina ceramic, the piston moves slowly downward inside the inner groove, and the air flows slowly upward through the fine hole, thus avoiding the slight deformation of the alumina ceramic from affecting the testing work. Only when the lever moves downward quickly, causing the piston's downward movement speed to be insufficient, does button two separate from the lever. It is possible to perform maximum strength and qualified strength testing on the alumina ceramic as needed, while effectively ensuring the accuracy of the strength test.

[0017] 3. When the alumina ceramic strength testing device is in use, after the alumina ceramic is damaged, the right end of the lever moves rapidly downward until the bottom of the lever hits the top of the slide rod, pushing the slide rod into the inner side of the slide cavity. The slide rod compresses the second spring and the air in the slide cavity until the air pressure in the slide cavity is greater than the threshold of the pressure relief valve, causing the pressure relief valve to open and the air in the slide cavity to be released rapidly outward. This effectively uses the compression of the second spring and the air to buffer the lever, while releasing the compressed air outward through the pressure relief valve, reducing the swaying of the lever and thus effectively ensuring the safety of the lever and its components.

[0029] Please see Figures 1 to 9This invention provides a technical solution: a strength testing device for alumina ceramics, comprising a housing 1 and a base plate 2. An opening assembly is installed on the housing 1, comprising a cover plate 3 and a side door 4. A support assembly is installed at the bottom of the housing 1, comprising a pad 5 and a screw sleeve 8. A lifting assembly is installed at the bottom of the housing 1, comprising a motor 6 and a screw 7. A support assembly is installed on the housing 1, comprising a clamping plate 9 and an electromagnet 10. A pressing assembly is installed on the housing 1, comprising a lever 13 and a pressure rod 14. A pressure adjusting assembly is installed on the lever 13, comprising a counterweight 15 and a motor 17. A pressure regulating assembly is installed, comprising a motor 19 and a baffle 20.

A cover plate 3 is hinged to the top of the housing 1. A side door 4 is hinged to one side of the housing 1 and secured to one side of the housing 1 by a door lock. A pad 5 is installed on the bottom inner side of the housing 1. A motor 6 is bolted to the base plate 2. The top end of a screw sleeve 8 is welded to the bottom of the pad 5, and the bottom end of the screw sleeve 8 passes through the inner wall of the housing 1 and extends to the bottom of the housing 1. The bottom end of a screw rod 7 is welded to the output shaft of the motor 6. The top of the screw 7 is threaded onto the inner side of the screw sleeve 8. The bottom of the clamping plate 9 is secured to the inner wall of the bottom of the housing 1. Wedge patterns are provided on one side of the clamping plate 9 and at both ends of the pad 5. Both ends of the pad 5 are secured to one side of the clamping plate 9 by the wedge patterns. A sliding sleeve 11 is welded to the other side of the clamping plate 9. A groove is provided on the inner wall of the housing 1. The electromagnet 10 is welded to the inner side of the groove. One end of the sliding sleeve 11 extends into the inner side of the groove. The inner wall of the sliding sleeve 11 is connected to the electromagnet 10 by a spring 12. In use, the side door 4 is opened, and the alumina ceramic is placed on top of the pad 5. Then, according to the height of the alumina ceramic, the motor 6 moves the screw sleeve 8 and the pad 5 upwards through the screw 7 until the alumina ceramic is in place. The top of the alumina ceramic is clamped to the bottom of the pressure rod 14. The two ends of the pad 5 are supported at the bottom of the box 1 by the wedge pattern on the clamping plate 9. When performing strength testing on the alumina ceramic, it is only necessary to adjust the position of the counterweight 15 and amplify the pressure through the lever 13 to press the pressure rod 14 downward, thereby effectively performing strength testing on the alumina ceramic. During the strength testing process, the pad 5 is supported by the wedge pattern on the clamping plate 9, and the motor 6, screw 7 and screw sleeve 8 do not need to bear pressure, reducing equipment wear and ensuring the service life of the equipment. At the same time, the pressure is applied by lever 13, counterweight 15 and pressure rod 14. The structure is simple and will not easily cause wear or deformation, thus improving the service life of the equipment.

[0030] In this embodiment, one end of the lever 13 is mounted on the inner wall of the housing 1 via a pivot. The pressure rod 14 is welded to the bottom of one end of the lever 13 and is located on top of the pad 5. The counterweight 15 is fitted onto the outer side of the lever 13. A sliding cavity 26 is provided on the other side of the housing 1. A sliding rod 27 is fitted inside the sliding cavity 26. The bottom end of the sliding rod 27 is connected to the inner wall of the bottom of the sliding cavity 26 via a spring 29. The top end of the sliding rod 27 extends into the through groove 22. On one side, a pressure relief valve 28 is installed at the bottom of the sliding cavity 26. A micro-hole is formed at the bottom of the pressure relief valve 28. The sliding cavity 26 is connected to the outside of the pressure relief valve 28 through the micro-hole. An inner groove 30 is formed at the top of the other side of the housing 1. The inner groove 30 is located at the top of the other end of the lever 13. A piston 31 is fitted inside the inner groove 30. A button 32 is welded to the bottom of the piston 31. A fine hole 33 is formed at the top of the piston 31. The top of the inner groove 30 is connected to... The fine hole 33 is connected to the bottom of the inner groove 30. The box 1 is externally connected to a switch group. The switch group is connected to motor 1 6, motor 3 19, motor 4 23, button 1 21 and button 2 32 and electromagnet 10 through wires. Button 1 21 and button 2 32 are both connected to motor 2 17 through wires. After the alumina ceramic is damaged, the right end of lever 13 moves downward quickly until the bottom of lever 13 hits the top of slide rod 27 and pushes slide rod 27 into the inner side of slide cavity 26. Slide rod 27 compresses spring 2 29 and the air in slide cavity 26 until the air pressure in slide cavity 26 is greater than the threshold of pressure relief valve 28, so that pressure relief valve 28 is pushed open and the air in slide cavity 26 is released outward quickly. The compression of spring 2 29 and air is used to buffer lever 13. At the same time, the compressed air is released outward through pressure relief valve 28 to reduce the shaking of lever 13, thereby effectively ensuring the safety of lever 13 and its components.

[0031] In this embodiment, a through groove 22 is provided on the other side of the housing 1. The other end of the lever 13 extends to the inner side of the through groove 22. The second motor 17 is bolted to the top of the other end of the lever 13. A lead screw 16 is mounted on the output shaft of the second motor 17. Both ends of the lead screw 16 are mounted on the top of the lever 13 via bearings. The counterweight 15 is threaded onto the outer side of the lead screw 16. The third motor 19 is bolted to the top of one end of the lever 13. A second lead screw 18 is mounted on the output shaft of the third motor 19. Both ends of the second lead screw 18 are mounted on the top of the lever 13 via bearings. An opening is provided on the inner side of the counterweight 15. The opening is fitted onto the outer side of the second lead screw 18. The baffle 20... The bottom is secured to the top of lever 13. The baffle 20 is threaded onto the outer side of lead screw 18. A through-hole is provided on the baffle 20, which is fitted onto the outer side of lead screw 16. A button 21 is welded to the inner side of the baffle 20. Indicator blocks are welded to one end of both lead screw 16 and lead screw 18. A graduation mark is provided at the top of the other end of lever 13. A pressure mark is engraved on the top of lever 13, and the graduation mark cooperates with the pressure mark. Motor 23 is bolted to the inner side of the other side of housing 1. Screw 24 is mounted on the output shaft of motor 23. A groove is provided on the other side of housing 1. The bottom end of support sleeve 25 is threaded onto the outer side of screw 24. The outer side of the end is stuck on the inner wall of the groove. The top of the support sleeve 25 passes through the groove and the through slot 22 and extends to the bottom of the other end of the lever 13. When it is necessary to perform qualified strength testing on the alumina ceramic, the cover plate 3 is opened. Motor 3 19 drives the baffle 20 to move through the screw 2 18 until the baffle 20 moves to the position corresponding to the strength. Then, motor 4 23 and motor 2 17 are opened. Motor 4 23 pushes the support sleeve 25 downward through the screw 2 24. The right end of the lever 13 loses the support of the support sleeve 25. Motor 2 17 pushes the counterweight 15 to move to the right on the lever 13 through the screw 1 16 until the counterweight 15 presses the button 1 21. Motor 2 17 stops working so as to test whether the alumina ceramic can withstand the required pressure strength. When it is necessary to perform qualified strength testing on the alumina ceramic, the cover plate 3 is opened. Motor 3 19 drives the baffle 20 to move through the screw 1 16 until the counterweight 15 presses the button 1 21. Motor 2 17 stops working so as to test whether the alumina ceramic can withstand the required pressure strength. When performing maximum strength testing on the alumina ceramic, motor 19 pushes the baffle 20 to the rightmost end via lead screw 18. Then, motor 17 is activated, and it pushes the counterweight 15 to the right via lead screw 16 until the alumina ceramic is damaged. This causes the top of the right end of lever 13 to separate from button 32, and motor 17 stops working. The precise strength value can be determined by the pressure value corresponding to counterweight 15 and the scale corresponding to the indicator block on lead screw 16. When lever 13 moves slightly and slowly downward due to the pressure of the pressure rod 14 on the alumina ceramic, piston 31 moves slowly downward inside the inner groove 30, and air flows slowly upward through the fine hole 33, thus preventing slight deformation of the alumina ceramic from affecting the testing process.Only when lever 13 moves rapidly downwards, causing insufficient downward movement of piston 31 and resulting in button 32 separating from lever 13, can the maximum and qualified strength tests of alumina ceramics be performed as needed, while effectively ensuring the accuracy of the strength test.

[0032] The alumina ceramic strength testing device provides power to all electrical equipment via an external power supply. In use, the side door 4 is opened, and the alumina ceramic is placed on top of the pad 5. Based on the height of the alumina ceramic, the motor 6 moves the screw sleeve 8 and pad 5 upwards via the screw rod 7 until the top of the alumina ceramic is secured to the bottom of the pressure rod 14. The two ends of the pad 5 are supported at the bottom of the housing 1 by wedge patterns on the clamping plate 9. When performing strength testing on the alumina ceramic, simply adjust the position of the counterweight 15 and amplify the pressure through the lever 13 to press the pressure rod 14 downwards, thus effectively testing the alumina ceramic's strength. During the strength testing process, the pad 5 is supported by the wedge patterns on the clamping plate 9. The motor 6, screw... Rod 7 and screw sleeve 8 do not bear pressure, reducing equipment wear and ensuring equipment lifespan. Simultaneously, lever 13, counterweight 15, and pressure rod 14 are used for pressure application. The simple structure prevents wear and deformation, further extending equipment lifespan. When alumina ceramics require strength testing, cover plate 3 is opened. Motor 3 19 moves baffle 20 via screw 2 18 until it reaches the corresponding strength position. Then, motor 4 23 and motor 2 17 are opened. Motor 4 23 pushes support sleeve 25 downwards via screw 2 24, removing support sleeve 25 from the right end of lever 13. Motor 2 17 then pushes counterweight 15 to the right on lever 13 via screw 1 16 until counterweight 15 presses the button. 1. Motor 2, 17 stops working to test whether the alumina ceramic can withstand the required pressure strength. When the maximum strength test of the alumina ceramic is required, Motor 3, 19 pushes the baffle 20 to the rightmost end through the lead screw 2, 18, and then Motor 2, 17 is turned on. Motor 2, 17 pushes the counterweight 15 to the right through the lead screw 1, 16, until the alumina ceramic is damaged, causing the top of the right end of the lever 13 to separate from the button 2, 32. Motor 2, 17 stops working. The precise strength value can be obtained through the pressure value corresponding to the counterweight 15 and the scale corresponding to the indicator block on the lead screw 16. When the lever 13 moves slightly and slowly downward due to the compression of the alumina ceramic by the pressure rod 14, the piston 31 moves slowly downward inside the inner groove 30. This allows air to flow slowly upwards through the fine holes 33, thus preventing slight deformation of the alumina ceramic from affecting the testing process. Only when the lever 13 moves rapidly downwards, causing insufficient downward movement of the piston 31, does the button 32 separate from the lever 13. This allows for maximum and qualified strength testing of the alumina ceramic as needed, while effectively ensuring the accuracy of the strength test. After the alumina ceramic is damaged, the right end of the lever 13 moves rapidly downwards until the bottom of the lever 13 hits the top of the slide rod 27, pushing the slide rod 27 towards the inside of the slide cavity 26. The slide rod 27 compresses the spring 29 and the air in the slide cavity 26 until the air pressure in the slide cavity 26 exceeds the threshold of the pressure relief valve 28, causing the pressure relief valve 28 to open.The air inside the sliding cavity 26 is rapidly released outwards, effectively using the compression of the air and the second spring 29 to cushion the lever 13. Simultaneously, the compressed air is released outwards through the pressure relief valve 28, reducing the swaying of the lever 13 and thus effectively ensuring the safety of the lever 13 and its components.
