It is usually made of metal materials, in a long strip shape, with certain strength and corrosion resistance. It is located inside the oil well, connecting the pump rod on the ground and the oil pump at the bottom of the oil well, and plays the role of transporting crude oil and driving the oil pump. The length and diameter of the sucker rod will vary depending on the specific oil well depth, geological conditions and production needs. The external thread processing device is a mechanical device used to process the external thread on the end of the sucker rod. These external threads are usually used to connect the sucker rod with other oil well equipment, such as oil pumps or pump rods. The use of external threads can ensure that the connection between the sucker rod and other equipment is firm and reliable, and can withstand the stress and torque under high pressure and intense movement.

[0003] In a conventional sucker rod external thread processing device, an operator usually needs to fix the sucker rod to be processed on a workbench of the processing device, adjust various components of the processing device, and then start the processing device, and the cutting knife begins to cut the external thread on the end of the sucker rod.

[0004] In a conventional sucker rod external thread processing device, an operator usually adjusts the processing device, starts the cutting knife of the processing device and begins cutting the external thread on the end of the sucker rod, thereby achieving a stabilizing effect on the sucker rod. However, this patent does not take into account the problem that the sucker rod external thread processing device can only fix sucker rods of uniform diameter due to the fixed diameter structure of the working table of the processing device. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a sucker rod external thread processing device, aiming to improve the problem that the existing sucker rod external thread processing device can only fix sucker rods with uniform diameters due to its single structure.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1 , Figure 2 and Figure 3The utility model provides an embodiment: a sucker rod external thread processing device, comprising a base plate 1, a support plate 2 is fixedly connected to the upper surface of the base plate 1, a motor 3 is fixedly connected to the side wall of the support plate 2, a turntable 4 is fixedly connected to the output end of the motor 3, a fixed column 5 is fixedly connected to the side wall of the turntable 4, a disc 6 is fixedly connected to the fixed column 5 at one end, a motor 2 is fixedly connected to the side wall of the turntable 4, a movable plate 8 is fixedly connected to the output end of the motor 27, the side wall of the movable plate 8 is fitted with the side wall of the disc 6, a connecting rod 9 is rotatably connected to the side wall of the movable plate 8, a slider 10 is rotatably connected to one end of the connecting rod 9, the side wall of the slider 10 is slidably connected to the inside of the disc 6, the side wall of the slider 10 is fixedly connected to the fixed plate 11, the inner wall of the fixed plate 11 is provided with an auxiliary component, the auxiliary component comprises a rubber strip 12, and the side wall of the rubber strip 12 is fixedly connected to the inner wall of the fixed plate 11.

[0026] When processing the external thread of the sucker rod, first start the motor 2 7 to drive the moving plate 8 to deflect. The displacement of the moving plate 8 drives the connecting rod 9 to deflect, and at the same time pushes the slider 10 to slide inside the disc 6. The sliding of the slider 10 drives the fixed plate 11 to move synchronously. This step is to adjust the position of the clamping device to ensure that they can accurately clamp and fix the sucker rod so that there is no displacement or swing during the processing. At the same time, the rubber strip 12 plays a role in preventing the sucker rod from being damaged or worn during the processing. Then start the motor 13 to drive the turntable 4 to rotate. Under the connection of the fixed column 5, the rotation of the turntable 4 will drive the disc 6 to move synchronously.

[0027] Reference Figure 4 and Figure 5 An electric slide rail 13 is fixedly connected to the upper surface of the bottom plate 1, and a slider 14 is slidably connected to the side wall of the electric slide rail 13. A cutting knife 15 is arranged on the top of the bottom plate 1, and a fixed block 16 is fixedly connected to the side wall of the cutting knife 15. A sleeve 17 is fixedly connected to the lower surface of the fixed block 16. A sliding column 18 is fixedly connected inside the sleeve 17, and a limiting column 19 is fixedly connected inside the sliding column 18. The side wall of the limiting column 19 is fixedly connected inside the sleeve 17. A rotating shaft 20 is fixedly connected inside the sliding column 18. A card plate 21 is rotatably connected to the side wall of the rotating shaft 20. The bottom end of the card plate 21 is arranged at an arc angle. A spring 22 is arranged between the sliding column 18 and the card plate 21. One end of the spring 22 is fixedly connected to the side wall of the card plate 21, and the other end of the spring 22 is fixedly connected to the inside of the sliding column 18.

[0028] The sliding of the slider 2 14 is controlled by the electric slide rail 13, and the cutting knife 15 and the fixing block 16 are driven to move at the same time. The movement of the cutting knife 15 can realize the precise cutting of the external thread of the sucker rod. After the processing is completed, when the cutting knife 15 is worn or needs to be replaced, the fixing block 16 can be pulled upward to lift the sleeve 17 upward. At this time, the bottom of the card plate 21 slides along the inner groove of the slider 2 14. During the sliding process, the card plate 21 will deflect on the side wall of the shaft 20. The deflection of the card plate 21 will cause the spring 22 to compress into the inside of the sliding column 18. When the bottom of the card plate 21 is no longer in contact with the inside of the slider 2 14, the disassembly is completed. When installing a new cutting knife 15, the fixing block 16 can be pressed downward to make the bottom of the card plate 21 slide along the inner groove of the slider 2 14. At the same time, the card plate 21 will deflect on the side wall of the shaft 20, and the spring 22 will be compressed into the inside of the sliding column 18. When the bottom of the clamping plate 21 slides to the bottom of the slider 2 14 , the spring 22 loses pressure and resets to form a restriction, completing the installation. Through these steps, the cutting knife 15 can be effectively replaced.

[0029] Working principle: when it is necessary to process the external thread of the sucker rod, the moving plate 8 is driven to deflect by starting the motor 2 7, and the offset of the moving plate 8 drives the connecting rod 9 to deflect. While the connecting rod 9 is deflected, it pushes the slider 10 to slide inside the disc 6. The sliding of the slider 10 drives the fixed plate 11 to move synchronously, so as to clamp and fix the sucker rod that needs to be processed with external threads. At the same time, the rubber strip 12 will have an anti-wear effect. At this time, start the motor 13, and the motor 13 drives the turntable 4 to rotate. Under the connection of the fixed column 5, the rotation of the turntable 4 will drive the disc 6 to move synchronously, so as to achieve the effect of rotating the fixed sucker rod. At this time, the electric slide rail 13 is used to make the slider 2 14 slide, and at the same time drive the cutting knife 15 and the fixed block 16 to move. The movement of the cutting knife 15 achieves the effect of cutting the external thread of the sucker rod. After the processing is completed, when the cutting knife 15 is worn and needs to be replaced, we can pull the fixing block 16 upwards to lift the sleeve 17 upwards, and at the same time, the bottom of the card plate 21 will slide along the internal groove of the slider 2 14, and the card plate 21 will deflect the side wall of the shaft 20 while sliding. The deflection of the card plate 21 causes the spring 22 to be compressed toward the inside of the sliding column 18. When the bottom of the card plate 21 is no longer in contact with the inside of the slider 2 14, the disassembly is completed. When the new cutting knife 15 is installed, pressure can be applied downward to the fixing block 16 to make the bottom of the card plate 21 slide along the internal groove of the slider 2 14, and the card plate 21 will deflect the side wall of the shaft 20 while sliding. The deflection of the card plate 21 causes the spring 22 to be compressed toward the inside of the sliding column 18. When the bottom of the card plate 21 slides to the bottom of the slider 2 14, the spring 22 loses pressure and resets, thereby completing the installation.
