A limiting plate 39 is fixedly connected to the surface of the sliding rod 16, and the limiting plate 39 is used to limit the sliding rod 16.

[0039] The use steps of the present invention are as follows: when the steel pipe drilling auxiliary device is in use, the telescopic device 23 is first extended with the support plate 3 corresponding to the height position of the two slip rings 5, the steel pipe body 4 is placed on the surface of the support plate 3, and then the two slip rings 5 ​​are passed through to fix the steel pipe body 4 on the workbench 1, and then the support plate 3 is retracted into the lifting slot 2, and the moving frame 22 is pushed according to the position where the steel pipe body 4 needs to be punched. At this time, the moving block 21 moves in the moving slot 20 and moves the two slip rings 5 ​​to the position where the steel pipe body 4 needs to be punched, and then the movable plate 37 is manually pressed to move and move the insertion rod 9 away from the insertion hole 8 to squeeze the second spring 38, and then the arc block 7 is rotated, The arc block 7 moves with the fixed frame 10, the movable plate 12, the movable ring 13, the laser cutting head 14 and the arc positioning plate 17. The arc positioning plate 17 moves with the cutting hole 18 to correspond to the position of the hole. Then the insertion rod 9 is inserted into the insertion hole 8 for fixing. Then the second telescopic rod 53 extends with the movable plate 12, the movable ring 13, the laser cutting head 14 and the arc positioning plate 17 to approach the surface of the steel pipe body 4. The arc positioning plate 17 is squeezed by the surface of the steel pipe body 4. At this time, the arc positioning plate 17 moves with the sliding rod 16 to squeeze the first spring 19. As the second telescopic rod 53 continues to extend, the movable plate 12, the movable ring 13, the laser cutting head 14 and the arc positioning plate 17 are squeezed by the surface of the steel pipe body 4. The cutting head 14 continues to move. When the laser cutting head 14 reaches the cutting position distance, the second telescopic rod 53 stops moving. At this time, the laser cutting head 14 works to punch holes at the position where the steel pipe body 4 needs to be punched. The scheme moves the arc block 7 in the circular slide rail 6 with the fixed frame 10, the movable plate 12, the movable ring 13, the laser cutting head 14 and the arc positioning plate 17. The arc positioning plate 17 moves with the cutting hole 18 corresponding to the punching position. The punching position is initially positioned. The second telescopic rod 53 extends out with the movable plate 12, the movable ring 13, the laser cutting head 14 and the arc positioning plate 17 to approach the surface of the steel pipe body 4. The positioning plate 17 is squeezed by the surface of the steel pipe body 4. At this time, the arc-shaped positioning plate 17 moves with the slide rod 16 to squeeze the first spring 19. As the second telescopic rod 53 continues to extend, the movable plate 12, the movable ring 13, and the laser cutting head 14 continue to move. When the laser cutting head 14 reaches the cutting position distance, the laser cutting head 14 works to punch holes in the steel pipe body 4 at the position where holes need to be punched. Compared with the traditional drilling machine drilling holes in steel pipes, the punching auxiliary device makes the laser cutting head 14 punch holes in the steel pipe body 4 more accurately, which can improve the quality of the holes punched in the steel pipe body 4, thereby improving the production efficiency and product quality of the steel pipe body 4 processing and production.

The ring 48 is fixedly connected to the V-frame 46. According to the size of the hole to be punched, the electric telescopic rod 49 is telescopic and moves the V-frame 46 in the deep groove 45. At this time, the V-frame 46 moves with the ring 48 to adjust the fixing rod 47, and the laser cutting head 14 follows the fixing rod 47 to adjust. The second motor 52 rotates and drives the small gear 51 to rotate, thereby causing the large gear 43 to rotate and drive the V-frame 46 to rotate, so that the laser cutting head 14 rotates to cut holes of different sizes on the surface of the steel pipe body 4, thereby increasing the applicability and practicality of the punching device.

At this time, the V-shaped frame 46 moves with the ring 48 to adjust the fixed rod 47, and the laser cutting head 14 follows the fixed rod 47 to adjust. The second motor 52 rotates and drives the small gear 51 to rotate, thereby causing the large gear 43 to rotate. The V-frame 46 is driven to rotate, so that the laser cutting head 14 rotates to cut holes of different sizes on the surface of the steel pipe body 4. According to the size of the hole to be punched, the electric telescopic rod 49 is telescopic to move the V-frame 46 in the deep groove 45. At this time, the V-frame 46 moves with the ring 48 to adjust the fixed rod 47, and the laser cutting head 14 follows the fixed rod 47 to adjust. The second motor 52 rotates with the small gear 51, and then the large gear 43 rotates with the V-frame 46, so that the laser cutting head 14 rotates to cut holes of different sizes on the surface of the steel pipe body 4, thereby increasing the applicability and practicality of the punching device.
