[0035] Through the above technical solution, when the second motor 604 is started, the second motor 604 can drive the stud 603 to rotate, so that the second vertical plate 606 moves along the guide rod 602 and approaches the first vertical plate 605, so as to clamp and fix the steel pipe. At the same time, the third motor 608 can drive the turntable 607 on the right to rotate through the first gear 6074 and the second gear 609, thereby rotating the steel pipe, thereby realizing the fixation of steel pipes of different lengths and automatic adjustment of the drilling angle, which greatly improves the applicability and saves manpower.

[0036] Preferably, in order to enhance the firmness of the two turntables 607 in clamping the steel pipe, the present invention fixes a limit pin 6071 and an anti-slip rubber pad 6072 at the center position of the two turntables 607 close to one end surface.

At the same time, the dust suction fan 3 can collect the debris generated by the drilling to prevent the debris from being inhaled into the human body.

[0040] Embodiment 2:

[0041] Please refer to Figure 7 and Figure 8 In order to facilitate the processing of steel pipes with different diameters, the embodiment of the present invention also provides a second clamping and rotating assembly 7, including:

[0042] Slide rail 701, slide rail 701 is fixedly connected to workbench 1; frame 702, the bottom ends of the two frames 702 are fixedly connected with slide seats 703, the slide seats 703 are slidably connected to the surface of the slide rail 701, and the frame 702 can be moved horizontally to adapt to steel pipes of different lengths. An electric wheel 704 is arranged at the bottom end of the frame 702, and the electric wheel 704 has a built-in motor and can rotate automatically. Two symmetrical support plates 705 are arranged inside the frame 702 for supporting the steel pipe. The support plates 705 are arc-shaped plates that fit the steel pipe more closely. The left and right sides of the two support plates 705 that are away from each other at one end surface are fixedly connected with slide rods 7053, and the slide rods 7053 are slidably connected to the frame 702, and the slide rods 7053 are away from one end of the frame 702 A limit ring 7054 is fixedly connected to prevent the slide bar 7053 from detaching from the frame 702; a roller frame 706, wherein the two roller frames 706 are respectively located inside the two frames 702, and a roller 707 is rotatably connected inside the roller frame 706 for squeezing and fixing the steel pipe. A screw rod 708 is rotatably connected to the upper end of the roller frame 706, and the screw rod 708 penetrates through and is threadedly connected to the frame 702. A knob 709 is fixedly connected to the upper end of the screw rod 708 for facilitating the rotation of the screw rod 708. A limit column 7061 is slidably connected to the upper part of the frame 702, and the bottom end of the limit column 7061 is fixedly connected to the roller frame 706. The limit column 7061 can prevent the roller frame 706 from rotating with the screw rod 708 to keep the roller frame 706 stable in vertical movement.

[0043] Through the above technical solution, the two ends of the steel pipe are placed in the two frames 702, and the knob 709 is turned to lower the roller 707, and the steel pipe is pressed onto the support plate 705 so that the bottom of the steel pipe contacts the electric wheel 704, and the steel pipe can be fixed. Starting the electric wheel 704 can drive the steel pipe to rotate and process the steel pipe at different angles.

[0044] Preferably, in order to adapt to steel pipes of different diameters, a spring 7055 is sleeved on the surface of the slide rod 7053 of the present invention, and the spring 7055 is located between the adjacent support plate 705 and the frame 702 .

[0045] Through the above technical solution, the spring 7055 can squeeze the support plate 705, so that the two support plates 705 are close to each other, thereby clamping steel pipes of different diameters and improving applicability.

[0047] Through the above technical solution, after the two support plates 705 clamp the steel pipe, the guide wheel 7052 contacts the steel pipe. When the electric wheel 704 drives the steel pipe to rotate, the guide wheel 7052 will rotate together, thereby reducing the friction between the steel pipe and reducing energy loss.

[0048] In addition, the control terminal 8 in the present invention is internally provided with a PLC control system for controlling the electric push rod and the motor. The PLC control system is a prior art and is common knowledge in the art. It is not an improved technical point of this case and is therefore not described in detail here.

[0049] When the present invention is in use, the steel pipe is first placed on the workbench 1, and then fixed by the clamping and rotating assembly. When the first clamping and rotating assembly 6 is used, the right end of the steel pipe is inserted into the limit pin 6071, and the second motor 604 can drive the stud 603 to rotate, so that the second vertical plate 606 moves along the guide rod 602 and approaches the first vertical plate 605, so that the steel pipe can be clamped and fixed. At the same time, the third motor 608 can drive the right turntable 607 to rotate through the first gear 6074 and the second gear 609, thereby rotating the steel pipe, thereby achieving the fixation of steel pipes of different lengths and the automatic adjustment of the drilling angle; when the second clamping and rotating assembly 7 is used, the two ends of the steel pipe are placed in the two frames 702, the knob 709 is turned to make the roller 707 go down the frame, and the steel pipe is pressed on the support plate 705, so that the bottom of the steel pipe contacts the electric wheel 704, and the steel pipe can be fixed. Starting the electric wheel 704 can drive the steel pipe to rotate, and the steel pipe can be processed at different angles. Then, the drilling machine 4 is started, and each motor is controlled by the control terminal 8 to run according to the set program, the angle of the steel pipe and the horizontal position and vertical height of the drilling machine 4 are adjusted, and the steel pipe is drilled in all directions. When the first motor 502 is started, the first motor 502 can drive the synchronous wheel 501 to rotate to move the synchronous belt 503, and the synchronous belt 503 further drives the slider 403 to adjust the horizontal position of the drilling machine 4, so as to realize the automatic adjustment of the drilling position. At the same time, the dust suction fan 3 is started to collect the debris generated by the drilling. After the drilling is completed, the dust suction fan 3 and the drilling machine 4 are turned off, and the clamping rotating assembly is controlled to release the steel pipe, and the steel pipe can be taken out.

[0050] In summary, the present invention provides a steel pipe drilling machine for an oil perforating gun: on the one hand, by clamping and rotating the assembly, steel pipes of different lengths can be fixed, and the steel pipes can be driven to rotate and the drilling angle can be adjusted, without the need for manual selection of steel pipes, which greatly improves the application scope of the drilling machine and saves manpower. On the other hand, by moving the assembly, the drilling machine can be driven to move in the horizontal direction, and the horizontal position of the borehole can be adjusted, thereby achieving a more automatic drilling operation and greatly improving the efficiency and accuracy of the drilling. At the same time, the present invention is also designed with a dust suction fan, which can generate negative pressure above the collection bucket, and suck the debris generated by the drilling into the collection bucket to prevent the debris from being sucked into the human body and affecting human health.
