Description

Technical Field

[0001] The invention relates to the technical field of silicon carbide composite ceramic materials, and in particular to a detection device for silicon carbide composite ceramic materials. Background Art

[0002] Silicon carbide composite ceramic material is composed of multiple materials such as silicon carbide and ceramics. This composite material combines the advantages of silicon carbide and ceramics. It not only has the characteristics of good high temperature performance and strong impact resistance, but also has good electrical and thermal conductivity. At the same time, it completely overcomes the shortcomings of general ceramic materials such as brittleness and single function. It is recognized as an ideal high-temperature structural material, friction material and cryogenic material in the world.

Since components made of silicon carbide composite ceramic materials are affected by many external factors during actual use, simply testing their strength in one way cannot simulate the various usage situations encountered by silicon carbide composite ceramic materials during actual use, which affects the accuracy of the test results of silicon carbide composite ceramic materials and makes the detection reliability and accuracy of the testing devices in the prior art unable to meet people's usage needs.

[0043] As a technical optimization solution of the present invention, the limiting mechanism includes a plurality of winding wheels 21 rotatably mounted on the top of the first mounting plate 8, and the outer walls of the plurality of winding wheels 21 are all wound with pull ropes 30, and the ends of the plurality of pull ropes 30 away from the winding wheels 21 pass through the first mounting plate 8 and the second mounting plate 25 and are connected to the pressing plate 13.

[0045] As a technical optimization scheme of the present invention, the protective mechanism includes a storage groove 29 opened at the bottom of the first mounting plate 8, and a folded protective curtain 14 is installed inside the storage groove 29. Two first rectangular strips 34 and two second rectangular strips 35 are installed at the bottom end of the protective curtain 14. The outer walls of the two first rectangular strips 34 on the side close to each other are each provided with a second groove, and double-headed screws 37 are rotatably installed inside the two second grooves. The two ends of the two second rectangular strips 35 are respectively located inside the two second grooves, and the two ends of the double-headed screw 37 pass through the two ends of the two second rectangular strips 35. When the protective curtain 14 is in use, it is driven downward to unfold with the help of a preset driving device, so that the two first rectangular strips 34 and the two second rectangular strips 35 enter the interior of the movable plate 6 to cover and protect the fixed block 7 and the silicon carbide composite ceramic material clamped and fixed therein; a fourth servo motor is preset on the outer wall of one side of the two first rectangular strips 34, and the output end of the fourth servo motor is connected to one end of the double-headed screw 37, so that the double-headed screw 37 can be driven to rotate inside the second groove, so that the two second rectangular strips 35 can be moved and adjusted in the direction of approaching or moving away from each other.

[0046] As a technical optimization solution of the present invention, two telescopic limit rods 36 are installed on the outer wall of the side away from the two first rectangular strips 34, and the two ends of the movable plate 6 are provided with plug holes 10 adapted to the telescopic ends of the two telescopic limit rods 36. After the two first rectangular strips 34 enter the interior of the movable plate 6, the two telescopic limit rods 36 arranged on the outer wall of the side away from the two first rectangular strips 34 correspond to the positions of the plug holes 10 opened at the two ends of the movable plate 6, and the telescopic ends of the telescopic limit rods 36 are controlled to extend and be inserted into the corresponding plug holes 10, so that the positions of the two first rectangular strips 34 and the two second rectangular strips 35 can be limited and fixed, so that they can limit and fix the bottom end of the protective curtain 14, ensuring the stability of the use of the protective curtain 14.

[0047] In the present invention, when the user uses the device, the user controls the movable plate 6 to move from the top of the bottom plate 1 to the top of the two fixed plates 4, places the silicon carbide composite ceramic material to be detected on the top of the fixed block 7, and clamps and fixes it with the help of multiple clamps 11, and then controls the movable plate 6 to move to the top of the bottom plate 1, and controls the protective curtain 14 to unfold downward, so that the two first rectangular strips 34 and the two second rectangular strips 35 enter the interior of the movable plate 6 together, and uses the telescopic limit rod 36 set on the outer wall of the side away from the two first rectangular strips 34 to be inserted and fixed with the corresponding socket 10, and then controls the two second rectangular strips 35 to move in the direction of approaching each other and tightly abut against the outer walls of both sides of the fixed block 7, so that the bottom end of the protective curtain 14 is connected and fixed to the movable plate 6, which is convenient for the subsequent shielding and protection of the silicon carbide composite ceramic material during the detection process, and avoids the problem that the debris of the silicon carbide composite ceramic material is ejected outward and causes harm to the surrounding staff.

[0048] Then, the telescopic ends of the multiple second electric telescopic rods 12 are controlled to extend upward together, driving the pressing plate 13 to slowly move downward and contact the silicon carbide composite ceramic material. As the telescopic ends of the multiple second electric telescopic rods 12 continue to extend downward, the pressing plate 13 can continue to apply pressure to the silicon carbide composite ceramic material to detect whether the strength of the silicon carbide composite ceramic material meets the requirements.

[0049] Then, the two groups of limit plates 16 can be controlled to release the clamping fixation of the two protrusions 18, and the two rotating blocks can be controlled to drive the two second electric telescopic rods 12 to rotate in the direction away from each other, and then the first mounting plate 8 can be controlled to rotate downward 90 degrees with the rotating shaft 19 as the center, and then the two rotating blocks can be controlled to drive the two second electric telescopic rods 12 to rotate in the direction of approaching each other, so that the two groups of limit plates 16 are respectively located on both sides of the first mounting plate 8, which has an auxiliary supporting effect on the rotated first mounting plate 8, and then the other two second electric telescopic rods 1 are controlled. The first mounting plate 8 is driven to move downward after rotation until the protrusion 18 at one end of the first mounting plate 8 moves to the top of the silicon carbide composite ceramic material. When the first motor 28 is started to drive the rotating member 27 to rotate, the connecting rod 26 can be used to rotate the moving block 23 to move back and forth inside the rectangular groove 22, and the round rod 24 can be driven to move back and forth inside the round hole, so that the round rod 24 that is moving up and down can continuously knock the silicon carbide composite ceramic material, and continue to test the strength of the silicon carbide composite ceramic material.

[0050] Moreover, after the strength of the silicon carbide composite ceramic material is tested in the above two ways, the first mounting plate 8 and other components can be controlled to rotate and reset. Figure 1In the original state shown, the multiple winding wheels 21 are controlled to reverse rapidly, so that the pressure plate 13 at this time falls downward rapidly as the multiple pull ropes 30 are quickly unfolded, and collides with the silicon carbide composite ceramic material after the pressure plate 13 falls, so that the strength of the silicon carbide composite ceramic material can be further tested; and with the help of the telescopic adjustment of the telescopic ends of the multiple first electric telescopic rods 3, the height to which the pressure plate 13 falls downward can be adjusted, and the pressure plates 13 falling downward at different heights collide with the silicon carbide composite ceramic material, so that the strength of the silicon carbide composite ceramic material can be tested more comprehensively, thereby improving the credibility and accuracy of the strength test results of the silicon carbide composite ceramic material, and avoiding errors and uncertainties in the detection of silicon carbide composite ceramic materials by a single method.

[0051] After the above-mentioned pressing plate 13 has impacted the silicon carbide composite ceramic material, the multiple pull ropes 30 are reeled together by means of the positive rotation of the multiple reeling wheels 21, and the pressing plate 13 is pulled upward to reset. If the multiple reeling wheels 21 fail during use, or one or more of the pull ropes 30 are broken, resulting in the inability to continue to pull the pressing plate 13 upward to reset, the pressing plate 13 can be manually placed on the top of the fixed block 7, and then the multiple telescopic limit rods 36 located inside the movable plate 6 are controlled to be disengaged from the socket 10, and the protective curtain 14 is controlled to shrink upward by a certain length, driving the two second rectangular strips 35 and the bottom of the pressing plate 13 to move upward. With the help of the two second rectangular strips 35, as the protective curtain 14 continues to retract upward, the pressure plate 13 can be driven to move upward with the help of the two second rectangular strips 35, until the pressure plate 13 moves to a suitable position below the second mounting plate 25, and the two rotating seats 31 are controlled to drive the two groups of moving seats 33 to rotate downward together to a vertical state, which has a clamping and fixing effect on both sides of the pressure plate 13 below, ensuring that the pressure plate 13 can continue to be used in the subsequent detection process of silicon carbide composite ceramic materials. After the silicon carbide composite ceramic materials are detected, the winding wheel 21 or the broken pull rope 30 is repaired to avoid adverse effects on the detection of silicon carbide composite ceramic materials.

[0052] After the strength test of the silicon carbide composite ceramic material, the telescopic ends of the multiple second electric telescopic rods 12 can be extended downward to drive the bottom end of the pressing plate 13 to move to abut against the top of the silicon carbide composite ceramic material. As the first motor 28 drives the rotating part 27 to rotate, the connecting rod 26 is used to rotate to drive the moving block 23 to move back and forth inside the rectangular groove 22, so that the pressing plate 13 moves back and forth in a horizontal state, which can drive the pressing plate 13 to rub against the silicon carbide composite ceramic material, thereby being able to take advantage of the situation to test the wear resistance of the silicon carbide composite ceramic material, thereby improving the applicability of the entire detection device.

[0053] During the various strength tests and wear resistance tests on the silicon carbide composite ceramic material, the unfolded protective curtain 14 can shield the debris and dust generated by the rupture of the silicon carbide composite ceramic material during the test to avoid harm to surrounding staff.

[0054] Moreover, after the silicon carbide composite ceramic material is tested, as the first motor 28 drives the moving block 23, the second mounting plate 25 and the pressure plate 13 to move back and forth, it can simultaneously drive the cleaning brushes 32 arranged on both sides of the second mounting plate 25 to move back and forth, so that the cleaning brushes 32 moving back and forth can vibrate and knock the protective curtain 14 in the unfolded state, thereby shaking off the dust and debris attached to the inner wall of the protective curtain 14, which is beneficial to the subsequent use of the protective curtain 14.

[0055] After the debris and dust collected by the inner wall of the protective curtain 14 are vibrated to the top of the fixed block 7, the two rotating seats 31 are controlled to drive the two cleaning brushes 32 to rotate downward to a vertical state, and the protective curtain 14 is controlled to retract upward and return to its original position. With the help of the extension of the telescopic ends of the multiple second electric telescopic rods 12, the two cleaning brushes 32 in a vertical state are driven to move downward to the top of the fixed block 7. As the first motor 28 drives the second mounting plate 25 to move back and forth, the two cleaning brushes 32 are driven to move back and forth together to clean the debris and dust collected on the top of the fixed block 7. There is no need to manually clean the debris and dust on the top of the fixed block 7 subsequently, thereby improving the efficiency of debris and dust cleaning.
