The invention patent with the patent application number CN202210125242.8 discloses a strength detection device based on a ceramic fiber board. Through the settings of a working box and a pressing plate, the coordinated operation of a motor, a movable lead screw, and a movable sleeve is controlled. The output end of the motor drives the movable lead screw to rotate, and the pressing plate is driven to move downward through the movable sleeve, thereby detecting the strength of the ceramic fiber board. With the coordinated operation of the pressing plate and the magic tape layer, the staff adheres different materials to the bottom of the pressing plate through the magic tape layer, so as to conduct various tests on the ceramic fiber board, thereby improving the detection accuracy of the device. The invention patent with the patent application number CN202310627042.7 discloses a foamed ceramic board strength compression detection device and its detection method, including a workbench and a detector. A lifting assembly is arranged on the top of the workbench, the output end of the lifting assembly is connected with a support platform, the top of the support platform is connected with a second driving cylinder, the output end of the second driving cylinder is connected with a fixing plate, the detector is connected to the bottom of the fixing plate, and positioning components matched with the detector are arranged on both sides of the fixing plate. A clamping assembly and a protection assembly are arranged on the top of the workbench. Among them, a linkage assembly for driving the clamping assembly to fix the foamed ceramic board is arranged at the output end of the lifting assembly, and an adjusting assembly for driving the protection assembly to move vertically up and down is arranged at the bottom of the clamping assembly; the operation of the present invention is simple and convenient to use. It can not only conveniently fix the foamed ceramic board to be detected, but also play a good protection effect during the detection process, avoiding the occurrence of potential safety hazards. According to the disclosed technical solution, when the existing ceramic strength detection equipment is in use, on the one hand, the strength detection equipment often needs to apply high-strength pressure to alumina ceramics, which is likely to cause greater wear on the pressure application equipment and is not conducive to ensuring the service life of the equipment; on the other hand, during the strength detection work, it is not possible to quickly perform destructive detection and qualified standard detection as needed. At the same time, during the detection work, the detection result is likely to produce errors due to insensitive control, which is not conducive to ensuring the detection accuracy; on the third hand, at the moment when the alumina ceramic is crushed, the equipment is likely to be damaged due to the rapid release of the pressure of the pressure application equipment, which is not conducive to ensuring the working safety of the equipment.

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

[0015] 1. When the strength detection device for the alumina ceramic is in use, open the side door, place the alumina ceramic on the top of the backing plate, and then according to the height of the alumina ceramic, the first motor moves the screw sleeve and the backing plate upward through the first screw until the top of the alumina ceramic is clamped at the bottom end of the pressure rod. The two ends of the backing plate are supported at the bottom of the box body by the wedge patterns on the clamping plate through the wedge patterns. When performing the strength detection work on the alumina ceramic, only by adjusting the position of the counterweight and magnifying the pressure through the lever and then squeezing the pressure rod downward can the strength detection work of the alumina ceramic be effectively carried out. During the strength detection process, the backing plate is supported by the wedge patterns on the clamping plate, and the first motor, the first screw, and the screw sleeve do not need to bear the pressure, reducing the wear of the equipment and ensuring the service life of the equipment. At the same time, using the lever, the counterweight, and the pressure rod for the pressing work, the structure is simple and it will not easily cause wear, deformation and other conditions, improving the service life of the equipment.

[0016] 2. When the strength detection device for the alumina ceramic is in use, when it is necessary to perform the qualified strength detection work on the alumina ceramic, open the cover plate, and the third motor drives the baffle to move through the second screw until the baffle moves to the position corresponding to the strength. Then turn on the fourth motor and the second motor. The fourth motor pushes the support sleeve downward through the second screw, and the right end of the lever loses the support of the support sleeve. The second motor pushes the counterweight to move to the right on the lever through the first screw until the counterweight presses the first button, and the second motor stops working, so as to detect whether the alumina ceramic can withstand the required pressure strength. When it is necessary to perform the maximum strength detection work on the alumina ceramic, the third motor pushes the baffle to the rightmost end through the second screw, and then turn on the second motor. The second motor pushes the counterweight to move to the right through the first screw until the alumina ceramic is damaged, so that the top of the right end of the lever is separated from the second button, and the second motor stops working. The accurate value of the strength can be obtained through the pressure value corresponding to the counterweight and the graduation scale corresponding to the indicating block on the first screw. When the lever moves slightly and slowly downward due to the extrusion of the pressure rod on the alumina ceramic, the piston moves slowly downward inside the inner groove, and the air slowly flows upward through the fine holes, thereby avoiding affecting the detection work due to the slight deformation of the alumina ceramic. Only when the lever moves downward rapidly, the downward movement speed of the piston is insufficient, resulting in the separation of the second button from the lever. The maximum strength and qualified strength detection work of the alumina ceramic can be carried out according to the needs, and at the same time, the accuracy of the strength detection is effectively guaranteed.

[0017] 3. When the strength detection device of the alumina ceramic is in use, after the alumina ceramic is damaged, the right end of the lever quickly moves downward until the bottom of the lever hits the top of the sliding rod and pushes the sliding rod towards the inside of the sliding cavity. The sliding rod compresses the second spring and the air in the sliding cavity until the air pressure in the sliding cavity is greater than the threshold value of the pressure relief valve, causing the pressure relief valve to be pushed open. The air in the sliding cavity is quickly released outwards, effectively using the compression of the second spring and the air to buffer the lever. At the same time, the compressed air is released outwards through the pressure relief valve, reducing the shaking of the lever, and thus effectively ensuring the safety of the lever and each component on the lever.

A groove is provided on the inner wall of the box body 1. The electromagnet 10 is welded inside the groove. One end of the sliding sleeve 11 extends into the groove. The inner wall of the sliding sleeve 11 is connected to the electromagnet 10 through a first spring 12. When in use, open the side door 4, place the alumina ceramic on the top of the backing plate 5, and then, according to the height of the alumina ceramic, the first motor 6 moves the screw sleeve 8 and the backing plate 5 upward through the first screw rod 7 until the top of the alumina ceramic is tightly clamped at the bottom end of the pressing rod 14. Both ends of the backing plate 5 are supported on the bottom of the box body 1 by the wedge patterns on the clamping plate 9 through the wedge patterns. When performing the strength detection work on the alumina ceramic, only need to adjust the position of the counterweight 15, and magnify the pressure through the lever 13 and then squeeze the pressing rod 14 downward, thereby effectively performing the strength detection work on the alumina ceramic. During the strength detection process, the backing plate 5 is supported by the wedge patterns on the clamping plate 9. The first motor 6, the first screw rod 7 and the screw sleeve 8 do not need to bear the pressure, reducing the wear of the equipment and ensuring the service life of the equipment. At the same time, use the lever 13, the counterweight 15 and the pressing rod 14 to perform the pressing work, with a simple structure and not easily prone to wear, deformation and other conditions, 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 box body 1 through a rotating shaft. The pressing rod 14 is welded to the bottom of one end of the lever 13. The pressing rod 14 is located on the top of the backing plate 5. The counterweight 15 is sleeved on the outer side of the lever 13. A sliding cavity 26 is formed on the other side of the box body 1. A sliding rod 27 is clamped 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 through a second spring 29. The top end of the sliding rod 27 extends to the inside of the through groove 22. A pressure relief valve 28 is installed at the bottom of the sliding cavity 26. Fine holes are formed at the bottom of the pressure relief valve 28. The sliding cavity 26 is communicated with the outside of the pressure relief valve 28 through the fine holes. An inner groove 30 is formed at the top of the other side of the box body 1. The inner groove 30 is located on the top of the other end of the lever 13. A piston 31 is clamped inside the inner groove 30. A second button 32 is welded to the bottom of the piston 31. Fine holes 33 are formed at the top of the piston 31. The top of the inner groove 30 is communicated with the bottom of the inner groove 30 through the fine holes 33. A switch group is externally connected to the box body 1. The switch group is connected to the first motor 6, the third motor 19, the fourth motor 23, the first button 21, the second button 32 and the electromagnet 10 through electric wires. The first button 21 and the second button 32 are both connected to the second motor 17 through electric wires. After the alumina ceramic is damaged, the right end of the lever 13 quickly moves downward until the bottom of the lever 13 hits the top end of the sliding rod 27 and pushes the sliding rod 27 inward into the sliding cavity 26. The sliding rod 27 compresses the second spring 29 and the air inside the sliding cavity 26 until the air pressure inside the sliding cavity 26 is greater than the threshold value of the pressure relief valve 28, causing the pressure relief valve 28 to be pushed open. The air inside the sliding cavity 26 is quickly released outward. The compression of the second spring 29 and the air is effectively utilized to buffer the lever 13. At the same time, the compressed air is released outward through the pressure relief valve 28 to reduce the shaking of the lever 13, thereby effectively ensuring the safety of the lever 13 and all components on the lever 13.

[0031] In this embodiment, a through groove 22 is formed in the other side of the box body 1. The other end of the lever 13 extends to the inside of the through groove 22. The second motor 17 is installed on the top of the other end of the lever 13 through bolts. A first lead screw 16 is installed on the output shaft of the second motor 17. Both ends of the first lead screw 16 are installed on the top of the lever 13 through bearings. The counterweight 15 is sleeved on the outer side of the first lead screw 16 through a thread. The third motor 19 is installed on the top of one end of the lever 13 through bolts. A second lead screw 18 is installed on the output shaft of the third motor 19. Both ends of the second lead screw 18 are installed on the top of the lever 13 through bearings. A through hole is formed in the inner side of the counterweight 15, and the through hole is sleeved on the outer side of the second lead screw 18. The bottom of the baffle 20 is stuck on the top of the lever 13. The baffle 20 is sleeved on the outer side of the second lead screw 18 through a thread. A through opening is formed in the baffle 20, and the through opening is sleeved on the outer side of the first lead screw 16. A first button 21 is welded on the inner side of the baffle 20. Indicating blocks are welded on one ends of the first lead screw 16 and the second lead screw 18. A graduation scale is formed on the top of the other end of the lever 13, and a pressure scale is engraved on the top of the lever 13. The graduation scale is matched with the pressure scale. The fourth motor 23 is installed on the inner side of the other side of the box body 1 through bolts. A second screw rod 24 is installed on the output shaft of the fourth motor 23. A ribbed groove is formed in the other side of the box body 1. The bottom end of the support sleeve 25 is sleeved on the outer side of the second screw rod 24 through a thread. The outer side of the bottom end of the support sleeve 25 is stuck on the inner wall of the ribbed groove. The top end of the support sleeve 25 passes through the ribbed groove and the through groove 22 and extends to the bottom of the other end of the lever 13. When the qualified strength detection work of the alumina ceramic needs to be carried out, the cover plate 3 is opened. The third motor 19 drives the baffle 20 to move through the second lead screw 18 until the baffle 20 moves to the position corresponding to the strength. Then the fourth motor 23 and the second motor 17 are turned on. The fourth motor 23 pushes the support sleeve 25 downward through the second screw rod 24. The right end of the lever 13 loses the support of the support sleeve 25. The second motor 17 pushes the counterweight 15 to move rightward on the lever 13 through the first lead screw 16 until the counterweight 15 presses the first button 21, and then the second motor 17 stops working, so as to detect whether the alumina ceramic can withstand the required pressure strength. When the maximum strength detection work of the alumina ceramic needs to be carried out, the third motor 19 pushes the baffle 20 to the rightmost end through the second lead screw 18, and then the second motor 17 is turned on. The second motor 17 pushes the counterweight 15 to move rightward through the first lead screw 16 until the alumina ceramic is damaged, so that the top of the right end of the lever 13 is separated from the second button 32, and then the second motor 17 stops working. The accurate value of the strength can be obtained through the pressure value corresponding to the counterweight 15 and the graduation scale corresponding to the indicating block on the first lead screw 16. When the lever 13 moves slightly and slowly downward due to the extrusion of the alumina ceramic by the pressure rod 14, the piston 31 moves slowly downward inside the inner groove 30, and the air slowly flows upward through the fine holes 33, thereby avoiding the influence on the detection work due to the slight deformation of the alumina ceramic.Only when the lever 13 moves rapidly downward, causing the downward movement speed of the piston 31 to be insufficient and resulting in the separation of the button two 32 from the lever 13, can the maximum strength and qualified strength detection of alumina ceramics be carried out as needed, while effectively ensuring the accuracy of strength detection.

[0032] The strength detection device for this alumina ceramic provides electrical energy for all electrical equipment through an external power supply. When in use, open the side door 4, place the alumina ceramic on the top of the backing plate 5, and then according to the height of the alumina ceramic, the first motor 6 moves the screw sleeve 8 and the backing plate 5 upward through the first screw 7 until the top of the alumina ceramic is clamped at the bottom end of the pressure rod 14. Both ends of the backing plate 5 are supported at the bottom of the box body 1 by the wedge patterns on the clamping plate 9 through the wedge patterns. When conducting the strength detection work on the alumina ceramic, only by adjusting the position of the counterweight 15 and amplifying the pressure through the lever 13 and then squeezing the pressure rod 14 downward can the strength detection work on the alumina ceramic be effectively carried out. During the strength detection process, the backing plate 5 is supported by the wedge patterns on the clamping plate 9, and the first motor 6, the first screw 7, and the screw sleeve 8 do not need to bear the pressure, reducing the wear of the equipment and ensuring the service life of the equipment. At the same time, using the lever 13, the counterweight 15, and the pressure rod 14 for the pressing work, the structure is simple and it will not easily cause wear, deformation, etc., improving the service life of the equipment. When it is necessary to conduct the qualified strength detection work on the alumina ceramic, open the cover plate 3, and the third motor 19 drives the baffle 20 to move through the second screw 18 until the baffle 20 moves to the position corresponding to the strength. Then turn on the fourth motor 23 and the second motor 17. The fourth motor 23 pushes the support sleeve 25 downward through the second screw 24, and the right end of the lever 13 loses the support of the support sleeve 25. The second motor 17 pushes the counterweight 15 to move to the right on the lever 13 through the first screw 16 until the counterweight 15 presses the first button 21, and the second motor 17 stops working, so as to detect whether the alumina ceramic can withstand the required pressure strength. When it is necessary to conduct the maximum strength detection work on the alumina ceramic, the third motor 19 pushes the baffle 20 to the rightmost end through the second screw 18, and then turn on the second motor 17. The second motor 17 pushes the counterweight 15 to move to the right through the first screw 16 until the alumina ceramic is damaged, causing the top of the right end of the lever 13 to separate from the second button 32, and the second motor 17 stops working. The accurate value of the strength can be obtained through the pressure value corresponding to the counterweight 15 and the graduation scale corresponding to the indicating block on the first screw 16. When the lever 13 moves slowly downward slightly due to the extrusion of the alumina ceramic by the pressure rod 14, the piston 31 moves slowly downward inside the inner cavity 30, and the air slowly flows upward through the fine holes 33, thereby avoiding affecting the detection work due to the slight deformation of the alumina ceramic. Only when the lever 13 moves downward rapidly, the downward movement speed of the piston 31 is insufficient, resulting in the separation of the second button 32 from the lever 13. It is possible to conduct the maximum strength and qualified strength detection work on the alumina ceramic according to needs, and at the same time effectively ensure the accuracy of the strength detection. After the alumina ceramic is damaged, the right end of the lever 13 moves downward rapidly until the bottom of the lever 13 hits the top end of the slide rod 27 and pushes the slide rod 27 inward into the slide cavity 26. The slide rod 27 compresses the second spring 29 and the air in the slide cavity 26 until the air pressure in the slide cavity 26 is greater than the threshold value of the pressure relief valve 28, causing the pressure relief valve 28 to be pushed open.The air in the sliding cavity 26 is quickly released outward, effectively using the compression of the second spring 29 and the air to buffer the lever 13. At the same time, the compressed air is released outward through the pressure relief valve 28 to reduce the shaking of the lever 13, thereby effectively ensuring the safety of the lever 13 and each component on the lever 13.
