The grinding head 71000 is connected to the output end of the second drive motor 7900. When the clamping and rotating mechanism 6000 clamps the flange and rotates it, the third cylinder 7100 starts to drive the sliding mounting block 7200 to move toward the flange direction, and the sliding mounting block 7200 drives the mounting arm 7300 to move. When it moves to the designated position, the third cylinder 7100 stops running, the second stepper motor 7400 starts to drive the third driving gear 7600 to rotate, the fourth rack 7700 moves downward and drives the grinding head 71000 to reach the designated position, and the second drive motor 7900 is started for grinding. Different positions, namely the circular hole and the flange circumference, can be ground by adjusting the running distance of the third cylinder 7100.

[0021] Working principle: After the staff places the flange blank on the flange placement platform 4000, the first hydraulic cylinder 5200 is started to drive the sliding block 5300 to move upward, and the sliding block 5300 drives the inclined top block 5510 to move upward. The inclined top block 5510 contacts the inclined slide block 5520, that is, the first inclined surface 5511 contacts the second inclined surface 5521 and pushes the inclined slide block 5520 to move toward the flange placement platform 4000. At the same time, the spring guide rod 5550 moves to compress the spring 5560. At the same time, the sliding block 5300 moves upward and drives the first rack to move upward through the first rack connecting frame 5620. The first rack drives the first transmission gear 5640 to rotate, and the first transmission gear 5640 drives the second rack 5650 to move downward. The second rack 5650 drives the pressing block 5670 to press the flange at the edge of the flange. At the same time, the sliding block 5300 moves upward, driving the third rack 2700 to move upward, and the third rack 2700 drives the second transmission gear 2600 to rotate. The rotation of the second transmission gear 2600 drives the transmission bevel gear 2400 located on the same transmission shaft 2500 to rotate. The rotation of the transmission bevel gear 2400 drives the driven bevel gear 2300 meshing with it to rotate. The rotation of the driven bevel gear 2300 drives the rotating shaft to rotate. The rotation of the rotating shaft drives the support arm 2000 to rotate. After the support arm 2000 rotates to the working position, the first step is started to drive the first driving gear 3600. The first driving gear 3600 drives the first driven gear 3300 to rotate. The driven gear 3300 drives the mounting plate 3100 actively, and the mounting plate 3100 drives the flame cutting head 3200 to the designated position to cut a circular hole. Multiple rotations are performed to cut multiple circular holes. After the cutting is completed, the first hydraulic cylinder 5200 returns, and the sliding block 5300 moves downward, driving the inclined top block 5510 to move downward. The inclined slider 5520 returns to its original position under the elastic force of the spring 5560. At the same time, the sliding block 5300 moves downward, and the first rack is driven by the first transmission gear 5640 to make the second rack 5650 move upward, and the pressing block 5670 is reset. At the same time, the third rack 2700 is driven to move downward, and the third rack 2700 drives the second transmission gear 2600 to rotate, and the second transmission gear 2600 drives the transmission bevel gear The wheel 2400 rotates, the transmission bevel gear 2400 rotates to drive the driven bevel gear 2300 meshing therewith to rotate, the driven bevel gear 2300 rotates to drive the rotating shaft to rotate, the support arm 2000 is reset, and after the support arm 2000 is reset, it does not interfere with other structures during flange grinding. After the first hydraulic cylinder 5200 is reset after the circular hole cutting of the flange blank is completed, the third hydraulic cylinder 6700 works, and the piston rod of the third hydraulic cylinder 6700 drives the second movable connecting column 6500 to move forward, and the second movable connecting column 6500 drives the cylinder mounting frame 6800 to move forward. When the first cylinder 6900 and the second cylinder 61000 arrive directly above the flange, the third hydraulic cylinder 6700 stops moving, and the first cylinder 6900 and the second cylinder 61000 start at the same time.Drive the clamping head 61200 to clamp the flange. After clamping, the first cylinder 6900 and the second cylinder 61000 stop working. At this time, the second hydraulic cylinder 6100 starts to drive the first movable connecting column 6300 to move upward. The first movable connecting column 6300 drives the guide sleeve 6600 and the cylinder mounting frame 6800 to move upward. The first cylinder 6900 and the second cylinder 61000 drive the flange to move upward. The purpose of the flange moving upward is to prepare for the next step of grinding the flange. Therefore, at this time, the upward movement position only needs to not interfere with the flange placement platform 4000 when the flange rotates. Then the first drive motor 61300 starts to drive the second driving gear 61500 to rotate. The rotation of the second driving gear 61500 drives the second driven gear 61600 to rotate, and the clamping head 61200 connected to the second driven gear 61600 rotates. The head 61200 clamps the flange, and the flange and the other clamping head 61200 also rotate at this time. Then the third cylinder 7100 starts to drive the sliding mounting block 7200 to move toward the flange, and the sliding mounting block 7200 drives the mounting arm 7300 to move. When it moves to the specified position, the third cylinder 7100 stops running, and the second stepper motor 7400 starts to drive the third driving gear 7600 to rotate. The fourth rack 7700 moves downward and drives the grinding head 71000 to reach the specified position, and the second drive motor 7900 is started for grinding. Different positions, i.e., the circular hole and the flange circumference, can be ground by adjusting the running distance of the third cylinder 7100. After the grinding is completed, the fourth rack 7700 is reset, and then the third cylinder 7100 is reset, the second hydraulic cylinder 6100 is reset, and the third hydraulic cylinder 6700 is reset. The circular hole cutting of the flange blank and the grinding of the slag and burrs on the flange are completed.
