The drill rod connected by the drill bit connecting rod moves downward to contact the inner plate for drilling. As the drill rod continues to rotate and move downward, the grinding block connected to the slot column contacts the edge of the drilling hole position of the inner plate.

The connected driving rod 52 is driven to rotate by the rotation of the driving rod 52. The rotation of the driving rod 52 allows the connected pendulum column 53 to push the meshing gear teeth 54 to rotate around the connection point of the fixed axis frame 58. The rotation of the gear teeth 54 drives the connected cam disk 55 and the locking groove ring 56 to rotate together.

The driving rod 52 drives the spline rod 512 to provide driving force for drilling. At the same time, the driving rod 52 drives the pendulum column 53 and the gear teeth 54 to cooperate with the cam plate 55 to control the vertical guide rod 510 to move downward at equal intervals. The downward movement of the vertical guide rod 510 makes the pressing end 514 fit with the inner plate. The pressing end 514 presses the inner plate during drilling to avoid the position deviation of the inner plate during drilling and affect the drilling accuracy. At the same time, the cam plate 55 is used to cleverly control the sliding end 3 to automatically descend and automatically reset after a period of time, thereby improving the inner plate drilling efficiency and reducing the production cost of the overall punching structure.

When the locking spring rod 57 is aligned with the groove on the locking groove ring 56 in the rotating state again, the locking spring rod 57 is reset under the action of the reset spring to limit the locking groove ring 56, preventing the lug plate 55 connected to the locking groove ring 56 from rotating and resetting under the action of gravity. As the lug plate 55 rotates, the lug plate 55 gradually applies pressure to the arc groove folding plate 59 through the protrusion. When the arc groove folding plate 59 is compressed, it will slide along the guide rod block 511 through the connected vertical guide rod 510 and compress the elastic spring, and the downward movement of the vertical guide rod 510 drives the connected sliding end 3 to move. , so that the sliding end 3 drives the pressure end 4 and the lower pressure end 514 downward together, and the lower pressure end 514 moves downward and contacts the surface of the inner plate and stops moving, and then the lower pressure end 514 shrinks upward in the opposite direction into the pressure end 4. As the vertical guide rod 510 continues to move downward, the vertical guide rod 510 squeezes the compression spring in the shrinkage column 513 and shrinks into the shrinkage column 513 with the movement, so that the sliding end 3 connected to the vertical guide rod 510 shrinks into the pressure end 4, and the spline rod 512 connected to the sliding end 3 rotates under the drive of the driving rod 52, and the spline rod 512 drives the spline rod 512 to rotate. While providing driving for drilling, the driving rod 52 drives the pendulum column 53 and the gear teeth 54 to cooperate with the cam plate 55 to control the vertical guide rod 510 to move downward at equal intervals. The downward movement of the vertical guide rod 510 makes the pressing end 514 fit with the inner plate, and the inner plate is pressed by the pressing end 514 during drilling to avoid the position deviation of the inner plate during drilling and affect the drilling accuracy. At the same time, the cam plate 55 is used to cleverly control the sliding end 3 to automatically descend and automatically reset after a period of time, thereby improving the drilling efficiency of the inner plate and reducing the production cost of the overall punching structure. When the sliding end 3 moves downward, the connected spline rod 512 is driven downward together. While the spline rod 512 moves downward, it keeps rotating under the connection drive of the driving rod 52. The rotation of the spline rod 512 drives the connected connecting end column 61 to rotate. The rotation of the connecting end column 61 drives the connected drill connecting rod 63 and the slot column 67 to rotate together, and the drill rod 66 connected by the drill connecting rod 63 moves downward to contact the inner layer plate for drilling. As the drill rod 66 continues to rotate and move downward, the grinding block 69 connected to the slot column 67 contacts the edge of the drill hole in the inner layer plate, and the burrs are polished by the grinding block 69 contacting the edge of the hole, thereby preventing the burrs at the inner layer plate hole from falling off, simplifying the subsequent deburring process, and improving the processing efficiency. In addition, when the grinding block 69 is worn, the fastening screw ring 62 is rotated so that the fastening screw ring 62 no longer presses downward on the pressure block 612, and the pressure block 612 is manually driven When the movable pressure block 612 is separated from the positioning block 64 on the slot column 67, the old grinding block 69 can be removed together with the slot column 67, and then the new grinding block 69 is passed through the drill rod 66 through the through hole 68, so that the slot column 67 is aligned with the splicing groove 65 on the side of the drill connecting rod 63 and inserted, and then the slot column 67 and the drill connecting rod 63 located inside the connecting end column 61 are positioned by the positioning block 611, so that the positioning block 611 is matched with the positioning block 64 on the slot column 67 and the drill connecting rod 63, and then the fastening screw ring 62 is tightened to squeeze the pressure block 612, and the positioning is achieved by the structure of the pressure block 612 and the positioning block 64, and then the fastening screw ring 62 is used for reinforcement, thereby reducing the time required for disassembly of screw fixing, and at the same time, the structure of the splicing of the slot column 67 and the drill connecting rod 63 can be used to replace the local structure according to the degree of wear to reduce the use cost; When the driving rod 52 is in a rotating state, the peristaltic rotating handle 71 connected to the driving rod 52 will squeeze the hose 73 through the peristaltic wheel 72, and the peristaltic rotating handles 71 in different positions cooperate with each other to increase the negative pressure suction force, so that the part connected between the hose 73 and the connecting pipe 78 forms a vacuum negative pressure. At the same time, the fine particles generated by the drilling are accompanied by the outside air through the annular groove on the inner side of the downward pressure end 514 into the suction pipe 76, and enter the collecting end 75 through the suction pipe 76. At this time, the suction pipe 76 passes the air machine tiny particles into the filter cover 79 in the collecting end 75, and the air enters the connecting pipe 78 through the filter cover 79, while the tiny particles remain in the filter cover 79 and fall into the collecting tube 710. In this process, the filter introduced through the suction pipe 76 Part of the air through the mesh cover 79 will pass through the filter mesh cover 79 to directly blow the swing piece 711 to swing, and the swing piece 711 drives the connected swing bead 712 to swing, so that the swinging swing piece 711 pushes the arc rod 713 to squeeze the filter mesh cover 79 to vibrate, and the tiny particles attached to the inside will be shaken off by the vibration of the filter mesh cover 79, so as to avoid the attachment inside the filter mesh cover 79 affecting the air passing efficiency, and the tiny particles generated by drilling and deburring are collected to avoid the tiny particles from adhering to the inner plate, and the tiny particles are collected and turned over for subsequent processing. At the same time, the exhaust pipe 77 connected to the hose 73 discharges the air, and the air in the exhaust pipe 77 is discharged through the small holes on the end ring pipe, and the tiny dust attached to the grinding block 69 is blown away by the discharged air, so as to improve the deburring effect of the grinding block 69 after use.
