[0027] A fixing mechanism and a cleaning mechanism are arranged above the workbench 1 , and the workbench 1 provides a stable working environment to ensure the stability of the entire device during operation.

[0028] The fixing mechanism includes a transverse clamping unit and a longitudinal pressing unit;

[0029] The transverse clamping unit includes a chute 101, a partition plate 2, a baffle 3 and a first cylinder 301. The chute 101 is respectively opened on the front and rear sides of the workbench 1. The chute design allows the baffle 3 to move in the horizontal direction, so as to adapt to pipes of different widths. The bottom of the partition plate 2 is fixedly connected to the middle of the chute 101. The partition plate 2 is fixed in the middle of the chute 101, providing a fixed reference point for the baffles 3 on both sides, ensuring that the two baffles 3 can remain parallel and symmetrical when moving, so as to achieve stable clamping of the pipe. A slider is fixedly connected to the bottom of the baffle 3. The baffle 3 is the main clamping component of the transverse clamping unit. The slider at the bottom cooperates with the chute 101 to achieve transverse movement. The baffle 3 allows the pipe to obtain uniform clamping force on both sides, preventing the pipe from shaking during the drilling process. The side of the slider away from each other is fixedly connected to the output end of the first cylinder 301. The first cylinder 301 serves as a power source to drive the slider at the bottom of the baffle 3 to move in the chute 101. By controlling the expansion and contraction of the first cylinder 301, the distance between the baffles 3 can be conveniently adjusted to adapt to pipelines of different sizes;

[0030] The longitudinal pressing unit includes a telescopic plate 5, a connecting strip 501, a pressing block 502 and an electric push rod 503.

There are two groups of electric push rods 503, each group has two, which are respectively arranged on the front and rear sides of the upper surface of the baffle 3, and the two ends of the telescopic plate 5 are respectively fixedly connected to the output ends of the electric push rod 503 on the upper surfaces of the left and right baffles 3. The electric push rod 503 serves as a power source to drive the telescopic plate 5 to extend and retract. By controlling the telescopic length of the electric push rod 503, the pressing force of the pressing block 502 on the pipeline can be easily adjusted to adapt to pipelines of different materials and thicknesses. One end of the telescopic plate 5 is fixedly connected to the output end of the electric push rod 503. The telescopic plate 5 is the core component of the longitudinal pressing unit, and its length can be adjusted as needed. The design of the telescopic plate enables the device to adapt to pipelines of different lengths and achieve uniform pressing through the fixed connection at both ends. The top of the connecting strip 501 is fixedly connected to the middle of the bottom of the telescopic plate 5. The connecting strip 501 connects the telescopic plate 5 with the pressing block 502, ensuring the stability and accuracy of the pressing block 502 during the telescopic plate 5 extension and retraction process. The pressing block 502 is fixedly connected to the bottom of the connecting strip 501. The pressing block 502 is a component that directly contacts the pipeline and is responsible for pressing the pipeline in the longitudinal direction. The uniform pressure of the pressing block 502 can ensure the stability of the pipeline during the drilling process and improve the drilling accuracy. There are two groups of longitudinal pressing units, which are fixedly connected to the front and rear sides of the upper surface of the baffle 3 respectively. By setting the front and rear two groups of longitudinal pressing units, the pipeline can be pressed more evenly to ensure that the pipeline will not shake or move during the drilling process, thereby improving the accuracy and stability of the drilling.

[0031] The cleaning mechanism includes a cleaning box 7, a box door 701, a fixed block 1 702, a filter screen plate 1 703, a fixed block 2 704, a filter screen plate 2 705, a collecting pipe 706 and an air pump 8. The bottom of the cleaning box 7 is fixedly connected to the left side of the middle part of the upper surface of the placement plate 9. The cleaning box 706 is used to collect the debris generated during the drilling process to keep the working environment clean. The top of the collecting pipe 706 is fixedly connected to the right side of the bottom of the cleaning box 7, and the bottom of the collecting pipe 706 faces the drill bit 602. The collecting pipe 706 sucks the debris near the drill bit 602 into the cleaning box 7 to achieve automatic cleaning of the debris. The left side of the box door 701 is hinged to the front of the cleaning box 7 by a hinge, and the box door 701 facilitates the cleaning and maintenance of the inside of the cleaning box. Fixed block 1 702 and fixed block 2 704 are respectively provided with placement grooves, and fixed block 1 702 and fixed block 2 704 are respectively fixedly connected to the internal top surface of cleaning box 7, and fixed block 1 702 and fixed block 2 704 have two pieces, which are respectively arranged on the upper and lower sides of the inner wall of cleaning box 7, and the placement grooves are relatively placed, and fixed block 1 702 and fixed block 2 704 and the placement grooves inside thereof are used to install filter screen plates to achieve filtering and separation of debris. Filter screen plate 1 703 and filter screen plate 2 705 are respectively movably connected to the inside of the placement grooves, and filter screen plate 1 703 and filter screen plate 2 705 are effectively separated by graded filtration to facilitate subsequent processing. Air pump 8 is arranged on the left side of cleaning box 7, and air pump 8 provides power for the cleaning mechanism so that the debris can be sucked into cleaning box 7.

[0032] Working principle: Place the pipe to be drilled on the workbench 1 to ensure that the pipe is centered. When the pipe needs to be fixed on the device for drilling, the baffle 3 is moved in the slide 101 by controlling the extension and contraction of the first cylinder 301, thereby adjusting the distance between the two baffles 3 to accommodate pipes of different widths. Subsequently, the electric push rod 503 is started to extend the telescopic plate 5, and the pipe is longitudinally pressed by the pressing block 502 to ensure that the pipe remains stable during the drilling process.

[0033] The motor 601 is started to make the drill bit 602 start to rotate at high speed. As needed, the height of the drill bit 602 is adjusted by controlling the second cylinder 403 so that it contacts the surface of the pipeline. The drilling operation begins, and the drill bit 602 opens a hole in the pipeline under the drive of the motor.

[0034] During the drilling process, the air pump 8 starts to work, generating an airflow to suck the debris near the drill bit 602 into the cleaning box 7 through the collection pipe 706. After the debris enters the cleaning box 7, it first passes through the filter screen plate 1 703, and the larger particles of debris are intercepted. Subsequently, the smaller debris continues to pass through the filter screen plate 2 705 for secondary filtration to further separate smaller particles. The debris after two filtrations is collected at the bottom of the cleaning box 7, and the filtered airflow is discharged from the top of the cleaning box 7. After the drilling is completed, the motor 601 and the air pump 8 are turned off. The box door 701 is opened, and the debris collected in the cleaning box 7 is taken out for subsequent processing.
