[0024] A through hole is provided in the middle of the workbench 2. The through hole allows the debris generated by drilling to fall through the through hole and be collected uniformly. The movable plate 4 is rotatably connected to the workbench 2 through a threaded rod 6, and the lower end of the threaded rod 6 is controlled to rotate by a driving device, so that the movable plate 4 can slide freely up and down along the guide rod 3, thereby adjusting the position of the drill rod 511.

[0025] See also Figure 2 In order to quickly drill the pipe 7 on the workbench 2, the output shaft of the motor 51 is drivingly connected to one end of the driving wheel 52.

[0027] See also Figure 3 In order to quickly fix the pipe 7 on the workbench 2, the clamping mechanism 9 includes a hydraulic cylinder 91. The lower end of the hydraulic cylinder 91 is bolted to the upper end of the cross plate 8. The upper end of the hydraulic cylinder 91 is provided with a hydraulic rod 92. The upper end of the hydraulic rod 92 is provided with a lifting plate 93. The upper end of the lifting plate 93 is fixedly connected to a support rod 94. The upper end of the support rod 94 is fixedly connected to a mounting plate 95. The upper end of the mounting plate 95 is bolted to a cylinder 96.

The upper end of the hydraulic rod 92 is fixedly connected to the lower end of the lifting plate 93. The height of the support rod 94 is equal to the thickness of the workbench 2.

[0028] When it is necessary to drill a hole in the pipe 7, first, the hydraulic cylinder 91 is telescopically moved. A hydraulic rod 92 is provided at the telescopic end of the hydraulic cylinder 91. The movement of the hydraulic rod 92 causes the lifting plate 93 to move up and down. The lifting plate 93 drives multiple support rods 94 to rise. The support rods 94 lift the mounting plate 95. A cylinder 96 is provided on the mounting plate 95. At this time, the cylinder 96 rises from a height below the surface of the workbench 2. At this time, the cylinder 96 is located above the workbench 2. Then, multiple cylinders 96 are controlled to start, so that the clamping blocks 97 at their telescopic ends can clamp the pipe 7 to ensure that the pipe 7 remains stable during the drilling process. The telescopic movement of the hydraulic cylinder 91 is controlled by the hydraulic system. The hydraulic system transmits pressure to the lifting plate 93 through the hydraulic rod 92 to achieve fast and accurate positioning. The cylinder 96 is responsible for quickly releasing the clamping block 97 after the drilling is completed to facilitate the replacement or movement of the pipe 7, which not only improves work efficiency and reduces operation time, but also ensures the accuracy of drilling and the safety of the pipe 7.

[0029] Working principle: First, a through hole is opened in the middle part of the workbench 2. The setting of the through hole allows the debris generated by drilling to fall through the through hole and be collected uniformly. The movable plate 4 is rotatably connected to the workbench 2 through the threaded rod 6, and the lower end of the threaded rod 6 is controlled by the driving device to control its rotation, so that the movable plate 4 can slide up and down freely along the guide rod 3, thereby adjusting the position of the drill rod 511. The clamping mechanism 9 is provided to fix the pipe 7 to ensure that the pipe 7 does not move during the drilling process, thereby ensuring the accuracy of the drilling. The motor 51 serves as the power source, and transmits power to the driven wheel 54 through the driving wheel 52 and the synchronous belt 53, thereby driving the rotating rod 55 to rotate. The coupling 56 on the rotating rod 55 can absorb a certain amount of impact and vibration. The rotation of the rotating rod 55 is realized by rotating the rotating rod 55 to ensure the smoothness of the transmission. A plurality of bevel gears 58 are provided on the rotating rod 55. The number of bevel gears 58 and bevel gear 2 59 can be increased according to actual production needs. The meshing setting of bevel gear 1 58 and bevel gear 2 59 converts the rotational motion of the rotating rod 55 into vertical motion, so that the mounting seat 510 and the drill rod 511 can perform precise drilling operations. A common drill bit on the market can be used between the drill rod 511 and the mounting seat 510. The drill rod 511 and the mounting seat 510 are detachable, which is convenient for replacement according to the needs of drilling holes on different pipes 7, thereby increasing the practicality of the device. The structure of the entire device is reasonable and easy to operate, and can achieve efficient and precise multi-hole synchronous drilling operations.

[0030] Then, when it is necessary to drill the pipe 7, first, through the telescopic action of the hydraulic cylinder 91, a hydraulic rod 92 is provided at the telescopic end of the hydraulic cylinder 91. The movement of the hydraulic rod 92 causes the lifting plate 93 to move up and down. The lifting plate 93 drives multiple support rods 94 to rise. The support rods 94 lift the mounting plate 95. The mounting plate 95 is provided with a cylinder 96. At this time, the cylinder 96 rises from a height lower than the surface of the workbench 2. At this time, the cylinder 96 is located above the workbench 2. Then, the multiple cylinders 96 are controlled to start, so that the tightening blocks 97 at their telescopic ends can tighten against the pipe. 7, to ensure that the pipe 7 remains stable during the drilling process, the extension and retraction of the hydraulic cylinder 91 is controlled by the hydraulic system, and the hydraulic system transmits pressure to the lifting plate 93 through the hydraulic rod 92 to achieve fast and accurate positioning. The cylinder 96 is responsible for quickly releasing the clamping block 97 after the drilling is completed to facilitate the replacement or movement of the pipe 7, which not only improves work efficiency and reduces operation time, but also ensures the accuracy of drilling and the safety of the pipe 7. The above is the working process of the entire device, and the contents not described in detail in this manual belong to the existing technology known to professional and technical personnel in this field.
