[0018] A method for preparing silicon carbide honeycomb ceramics comprises the following steps:

[0019] S1. Positioning and cutting of honeycomb ceramics: Place the honeycomb ceramics in the middle of the first sliding table, start the first electric push rod to insert the insert block into the slot, start the dual-axis motor to drive the cutter to rotate, and the first electric push rod continues to extend to move the honeycomb ceramics toward the cutter and cut.

[0020] S2. Preparation for hole cleaning: After cutting, the first electric push rod is retracted, the electromagnet block is started to fix the second rotating rod and the first rotating rod, and the first sliding table is moved to insert the through rod and the penetrating rod into the honeycomb ceramic to prepare for cleaning the holes.

[0021] S3, top grinding: start the second electric push rod to make the sandpaper belt contact the honeycomb ceramic, start the second motor to drive the sandpaper belt to move, and grind the top of the honeycomb ceramic.

[0022] S4, outer wall grinding: After the top is ground, the second electric push rod retracts, and the dual-axis motor is started to drive the honeycomb ceramic to rotate, and the outer wall is ground in turn.

[0023] S5, impurity cleaning and resetting: After grinding is completed, the electromagnet block is disconnected, and the second rotating rod is reset under the action of the second spring. During the resetting process of the through rod, impurities are cleaned by the inserted rod.

[0024] In the present application, the fired honeycomb ceramic is first placed on the first sliding table, and the first sliding table is located in the middle of the honeycomb ceramic. Then the first electric push rod is started to drive the second sliding table to move. During the movement of the second sliding table, the knife seat can move under the action of the first spring until the knife seat hits the limit block on the left. At this time, the plug block is inserted into the slot. Then the dual-axis motor is started to drive the transmission shaft to rotate. The rotation of the transmission shaft can drive the second rotating shaft to rotate through the plug block and the slot, which can drive the cutter to rotate. The first electric push rod continues to extend to drive the second sliding table to move. The movement of the second sliding table can drive the second rack to move. The movement of the second rack can drive the gear to rotate. The rotation of the gear can drive the first rack to move. The movement of the first rack can drive the first sliding table to move, so that the second sliding table and the first sliding table are close to each other, which can drive the honeycomb ceramic to move toward the cutter, cutting while moving. During the movement of the first sliding table, the first rotating rod can be driven to slide on the second rotating rod.

[0025] The first and second electric push rods are retracted to drive the second sliding table to reset and move, and the first and second sliding tables can be driven away from each other through the gear, the first rack and the second rack. During the movement of the second sliding table, the sliding rod can be driven to slide in the knife seat until the sliding rod contacts one side of the knife seat. At this time, continuing to retract can drive the knife seat to move, so that the knife seat contacts the limit block on the right side. While the first sliding table moves, the two electromagnet blocks are started to fix the second rotating rod with the first rotating rod. At this time, the reset movement of the first sliding table can drive the two sliding bars to approach each other through the first rotating rod and the second rotating rod, and drive the sleeve rod to slide on the first rotating shaft, so that the two connecting plates are close to each other until the through rod and the through rod are inserted into the honeycomb ceramic. At this time, the first sliding table and the second sliding table are both away from the honeycomb ceramic. The through rod and the through rod can clean the holes in the honeycomb ceramic when they move in the honeycomb ceramic, and the impurities in the honeycomb ceramic can be pushed into the through rod during the movement of the through rod and the connecting plate.

[0027] After the top is polished, the second electric push rod is started to retract and drive the sandpaper belt away from the honeycomb ceramic, and then the dual-axis motor is started to drive the first rotating shaft to rotate. The rotation of the first rotating shaft can drive the sleeve rod to rotate, and the rotation of the sleeve rod can drive the connecting disk to rotate. The rotation of the connecting disk can drive the honeycomb ceramic to rotate through the penetrating rod, and the outer wall of the honeycomb ceramic is polished in turn;

[0028] After grinding is completed, disconnect the electromagnet block. At this time, the second rotating rod can slide in the first rotating rod under the action of the second spring, drive the two sliding strips to move away from each other, drive the connecting plate and the through rod to reset and move. During the reset movement of the through rod, the impurities collected inside can be cleaned by the insertion rod;

[0029] Finally, take out the processed honeycomb ceramics, place the honeycomb ceramics to be processed in the first sliding table, and it can also be used in cooperation with a robot for automatic loading and unloading.

[0030] Beneficial effects: In the present invention, for the preparation device of silicon carbide honeycomb ceramics, by placing the honeycomb ceramics in the first sliding table and starting the first electric push rod and the biaxial motor, it can not only drive the honeycomb ceramics to move under the abrasive belt, but also cut the honeycomb ceramics through the two cutting knives during the movement, which can improve the processing efficiency. Moreover, the first sliding table is in a U shape and can be adapted to the honeycomb ceramics, and the honeycomb ceramics will not move randomly during the cutting process, ensuring the stability during the cutting process;

[0031] In the present invention, for the preparation device of silicon carbide honeycomb ceramics, by starting the two electromagnet blocks, the first rotating rod and the second rotating rod can be fixed together. At this time, during the reset movement of the first sliding table, it can drive the two connecting plates to approach each other to clamp the honeycomb ceramics, and during the clamping process, the impurities in the holes of the honeycomb ceramics can be cleaned through the through rod and the through rod, and the cleaned impurities can be collected through the through rod, avoiding being left in the holes and eliminating the need for subsequent processing of the holes of the honeycomb ceramics again;

[0032] In the present invention, for the preparation device of silicon carbide honeycomb ceramics, by starting the biaxial motor, it can not only drive the cutting knives to rotate to cut the honeycomb ceramics, but also drive the connecting plate to rotate. During the rotation of the connecting plate, it can drive the honeycomb ceramics to rotate through the through rod and the holes on the honeycomb ceramics, so that multiple outer walls can cooperate with the abrasive belt for grinding without manual turning;

[0033] In the present invention, for the preparation device of silicon carbide honeycomb ceramics, by arranging an insertion rod corresponding to the through rod on the fixed disk, it can automatically clean the impurities collected in the through rod during the reset process for subsequent continuous processing without manual cleaning, making it more convenient to use;

[0034] In the present invention, through the cooperation of the first sliding table and the second sliding table, and the cutter driven by the dual-axis motor, the honeycomb ceramics can be stably cut, the clamping mechanism can not only clean the through holes of the honeycomb ceramics during the clamping process, but also realize the flipping of the honeycomb ceramics through the other output end of the dual-axis motor, thereby improving the flexibility of preparation, and the polishing mechanism utilizes the second electric push rod and the sandpaper belt to polish the outer wall of the cut honeycomb ceramics, thereby ensuring the surface quality of the product. In addition, the device also realizes precise coordination and automatic control of various components through ingenious transmission part design, coordination of the sliding rod and the spring, and a connecting rod structure controlled by the electromagnet block, thereby improving the preparation efficiency and product quality.

[0060] S1. First, place the fired honeycomb ceramic 7 on the first sliding table 6, and make the first sliding table 6 located in the middle of the honeycomb ceramic 7. Then, start the first electric push rod 11 to drive the knife seat 16 to move, so that the insert block 46 is inserted into the slot 47. Then, start the dual-axis motor 4 to drive the second rotating shaft 24 to rotate, which can drive the cutter 17 to rotate. The first electric push rod 11 continues to extend to drive the second sliding table 15 and the first sliding table 6 to approach each other, and can drive the honeycomb ceramic 7 to move toward the cutter 17, cutting while moving.

[0061] S2, after the cutting is completed, the first electric push rod 11 retracts and drives the first sliding table 6 and the second sliding table 15 away from each other, and at the same time, the two electromagnet blocks 44 are started to fix the second rotating rod 43 with the first rotating rod 42. At this time, the movement of the first sliding table 6 can drive the two connecting plates 5 to approach each other through the first rotating rod 42 and the second rotating rod 43, so that the through rod 35 and the penetrating rod 10 are inserted into the honeycomb ceramic 7 to clean the holes in the honeycomb ceramic 7;

[0062] S3, simultaneously start the second electric push rod 19 to extend, drive the sandpaper belt 9 to contact the honeycomb ceramic 7, and then start the second motor 23 to drive the rotating roller 22 to rotate, which can drive the sandpaper belt 9 to move and grind the top of the honeycomb ceramic 7;

[0063] S4, after the top is polished, the second electric push rod 19 is started to retract and drive the sandpaper belt 9 away from the honeycomb ceramic 7, and then the dual-axis motor 4 is started to drive the first rotating shaft 3 to rotate, which can drive the honeycomb ceramic 7 to rotate, and the outer wall of the honeycomb ceramic 7 is polished in turn;

[0064] S5. After the grinding is completed, the electromagnet block 44 is disconnected. At this time, the second rotating rod 43 can slide in the first rotating rod 42 under the action of the second spring 45, and drive the connecting plate 5 and the through rod 35 to reset and move. During the reset and movement of the through rod 35, the impurities collected inside can be cleaned by the insertion rod 39.

[0065] However, as is well known to those skilled in the art, the working principles and wiring methods of the dual-axis motor 4, the first electric push rod 11, the second electric push rod 19, the second motor 23 and the electromagnet block 44 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.

[0066] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
