step one, placing round silicon carbide honeycomb ceramics to be detected on a workbench 5, closing a first protective door 101, then starting a motor 603 to drive four screw rods 606 to rotate, enabling the screw rods 606 to drive corresponding centering rods 7 to move towards the middle in the rotating process and pushing the silicon carbide honeycomb ceramics to the position right below a detection block 3, then enabling a pressure sensor 8 to detect real-time pressure between the centering rods 7 and the silicon carbide honeycomb ceramics and sending the real-time pressure signal into a main controller, and controlling the motor 603 to rotate reversely according to the real-time pressure signal, wherein the four centering rods 7 are automatically reset.
In the first step, the motor 603 is used to drive the first bevel gear 604 to rotate, and the first bevel gear 604 cooperates with the four second bevel gears 605 to drive the screw rod 606 to rotate in the rotating process, and the screw rod 606 is in threaded connection with the centering rod 7, so that the screw rod 606 can drive the four centering rods 7 to move towards the middle in the rotating process and push the silicon carbide honeycomb ceramic to the position right below the detection block 3.
Step two, the hydraulic telescopic rod 2 is started to extend and drive the mounting plate 4 and the detection block 3 to move downwards, and because the gear 20 is rotationally connected with the second rotating shaft 18 through the one-way bearing, the gear 20 can not be driven to rotate the second rotating shaft 18 by the gear 20 after the mounting plate 4 drives the rack 21 to move downwards, and the pressure detection is carried out on the silicon carbide honeycomb ceramics after the detection block 3 moves downwards.
Step three, after the detection is completed, the hydraulic telescopic rod 2 contracts and drives the mounting plate 4 and the detection block 3 to move upwards, the mounting plate 4 can drive the rack 21 to move in the moving process, the rack 21 is meshed with the gear 20 and can drive the second rotating shaft 18 and the first belt wheel 19 to rotate, the first belt wheel 19 drives the second belt wheel 22, the first rotating shaft 12 and the disc 13 to rotate through the belt 23 in the rotating process, and at the moment, the disc 13 drives the movable rod 10 and the cleaning brush 1101 to reciprocate through the connecting rod 14 in the rotating process.
In the third step, the disc 13 drives the movable rod 10 and the cleaning brush 1101 to reciprocate once through the connecting rod 14, and when the disc 13 drives the connecting rod 14 to rotate for the upper half circle, the connecting rod 14 drives the movable rod 10 to move rightward along the guide rail 16, and the movable rod 10 can drive the cleaning brush 1101 to move rightward and push the detected fragments to the right side in the moving process; at this point the pieces are discharged through the weep 9 and fall into the magazine 15 for storage.
When the disc 13 drives the connecting rod 14 to rotate to the lower half circle, the connecting rod 14 drives the movable rod 10 to move leftwards along the guide rail 16, and the movable rod 10 can drive the cleaning assembly 11 to move leftwards and reset in the moving process.
After the storage box 15 is fully filled with fragments, the second protection door 102 is opened to clean out the fragments in the storage box 15.
Alterations, modifications, substitutions and variations of the embodiments herein will be apparent to those of ordinary skill in the art in light of the teachings of the present invention without departing from the spirit and principles of the invention.
