[0002] Oil drill pipe joints are key components for ultra-deep well drilling. The thread machining accuracy directly impacts the connection strength and sealing performance of the drill pipe. While CNC thread lathes exist in the prior art, they still rely on manual operation for loading, positioning, and unloading, resulting in the following significant drawbacks:

[0003] High dependence on manual labor: Existing equipment requires manual work to place workpieces one by one and adjust their positioning, which is inefficient and labor-intensive, making it difficult to meet the needs of large-scale production.

[0004] Low level of automation: The loading and unloading processes are not fully automated, and the processing is frequently interrupted, affecting production continuity and overall efficiency.

[0005] Moreover, if existing CNC lathes need to complete automatic loading and unloading of workpieces, they need to be operated in conjunction with external automation equipment, which takes up a large space, has high modification costs, and is not compatible with existing CNC lathes, making it difficult to promote widely.

[0048] Next, in combination with the accompanying drawings and the specific implementation mode, the present invention will be further described. It should be noted that, on the premise of no conflict, any combination of the following-described embodiments or technical features can form a new embodiment.

[0049] Embodiment 1

[0050] Please combine with Figures 1 - 12 , a thread processing device for manufacturing a thread of a super-deep well oil drill pipe joint proposed in this embodiment includes a bed body 100, a loading rack 600, a unloading rack 700, an auxiliary loading and unloading assembly 800, and a driving assembly 500. The bed body 100 is an existing thread CNC lathe, which has a tool rest 300 and a tool rest support 301. The tool rest 300 is equipped with tools for turning threads, and the tool rest support 301 can control the position of the tool rest 300 to work automatically.

[0051] In order to adapt to the existing thread processing lathe, a notch one 101 and a notch two 102 can be opened on one side of the bed body 100 (refer to Figure 7 ), and the bed body 100 has an automatic chuck 200 for loading the drill pipe joint 400; the automatic chuck 200 is an existing three-jaw chuck, which can automatically clamp the workpiece to be processed and drive the workpiece to rotate, so as to cooperate with the tools on the tool rest 300 to complete the operation of turning threads.

[0052] The loading rack 600 includes a supporting plate 602 and a loading plate 601, and a plurality of drill rod joints 400 that can roll are placed in an orderly manner on the supporting plate 602. The drill rod joints 400 pass through the notch 101 and are rotatably connected to the inner wall of the notch 101. When the supporting plate 602 is rotated to the lowest end close to the loading plate 601, the drill rod joint 400 located at the front moves to the loading plate 601, while the remaining drill rod joints 400 remain on the supporting plate 602. This ensures that only one drill rod joint 400 is moved to the loading plate 601 each time loading is performed, which facilitates orderly processing and eliminates the need for manual loading.

[0053] In order to improve work efficiency and facilitate the automatic transfer of the processed drill pipe joint 400, the unloading rack 700 is provided at the second gap 102;

[0054] In this solution, the auxiliary loading and unloading assembly 800 includes a blocking unit, a suction unit, and a blanking unit. The blocking unit is used to block the drill rod joint 400 on the loading plate 601 and make the drill rod joint 400 coaxial with the automatic chuck 200. The suction unit drives the drill rod joint 400 to be loaded and unloaded in the automatic chuck 200. The blanking unit is used to push the processed drill rod joint 400 to the blanking rack 700.

[0055] The driving assembly 500 is used to drive the auxiliary loading and unloading assembly 800 to move.

[0056] This embodiment is combined with reference Figures 1 - 4 The processing steps are roughly as follows:

[0057] Reference Figure 1 First, place multiple drill rod joints 400 to be processed on the carrier plate 602 in order, so that the blocking unit is above the loading plate 601. Then rotate the carrier plate 602 until its end close to the loading plate 601 is at its lowest point. After the drill rod joint 400 at the front moves to the loading plate 601, it is blocked by the blocking unit and stops at the loading station.

[0058] Reference Figure 2 Then, the material suction unit works and pushes the drill rod joint 400 into the automatic chuck 200 from one side. The automatic chuck 200 automatically clamps the drill rod joint and then rotates the carrier plate 602 in the opposite direction so that the remaining drill rod joints do not move toward the automatic chuck 200. At the same time, the position of the material blocking mechanism is adjusted to a suitable position to avoid interfering with the turning work. Finally, the tool is installed, the tool holder position is adjusted, and thread turning is performed.

[0059] Reference Figure 3 The drill pipe joint after turning is taken out from the automatic chuck 200 by the driving of the suction unit, and then the driving assembly 500 works to drive the auxiliary loading and unloading assembly to move to the side of the lower rack 700 as a whole. Figure 3The position shown;

[0060] Refer to Figure 4 , adjust the position of the material blocking unit so that the blanking unit is below the drill pipe joint, and use the driving force of the blanking unit to automatically push the drill pipe joint 400 onto the blanking rack 700.

[0061] In this solution, guardrails 603 are provided on all sides of the bearing plate 602 except the side close to the loading plate 601. A support 604 is provided at the bottom of the bearing plate 602. The support 604 is rotatably connected to the inner side wall of the notch 101 through a rotating shaft. A rotating power member 609 for driving the bearing plate 602 to rotate is also provided outside the bed body 100. In this solution, the rotating power member can be a servo motor. The servo motor is used to drive the rotating shaft to rotate, thereby driving the bearing plate 602 to rotate.

[0062] Refer to Figure 9 and Figure 10 , specifically, a cross beam 605 is fixed to the bottom of the loading plate 601. The other end of the cross beam 605 passes through the notch 101 and is connected to an end plate 610. A vertical power member 606 is installed in the notch 101, and a horizontal power member 607 is installed outside the notch 101. The output end of the horizontal power member 607 and the end plate 610 are slidably connected vertically. Specifically, a movable block 608 is slidably installed vertically inside the end plate 610. The output end of the horizontal power member 607 is connected to the movable block 608. The output end of the vertical power member 606 and the cross beam 605 are slidably connected horizontally. Specifically, a movable block 611 is fixed to the output end of the vertical power member 606. The movable block 611 and the bottom surface of the cross beam 605 are slidably connected. During specific operation, both the vertical power member 606 and the horizontal power member 607 can be electric push rods or cylinders.

[0063] Through the above structure, the horizontal position and vertical position of the loading plate 601 can be freely adjusted. One of the purposes of the adjustable vertical position is to ensure that when loading drill pipe joints with different diameters, they can be coaxially aligned with the automatic chuck. The purpose of the adjustable horizontal position is to be able to change the position of the loading plate to avoid interfering with the operation of the tool.

[0064] It should be noted that the material blocking unit includes an arc-shaped plate 813, a first blocking rod 804, and a second blocking rod 805. In this solution, the first blocking rod 804 and the second blocking rod 805 can be round rods. The first blocking rod 804 and the second blocking rod 805 are parallel to each other and are respectively fixed at both ends of the arc-shaped plate 813. The arc-shaped plate 813 is connected with a rotation driving mechanism. The rotation center line of the arc-shaped plate is collinear with the center line of the automatic chuck 200 to ensure stable and effective operation. Fixing bolts 812 are provided at both ends of the arc-shaped plate 813. Positioning holes for connecting with the fixing bolts 812 are provided on the first blocking rod 804 and the second blocking rod 805.

[0065] Reference can be made to Figure 1 、 Figure 2 and Figure 12 , the positions of the first shift lever 804 and the second shift lever 805 can, on the one hand, facilitate the movement of the drill pipe joint to the loading plate 601, and on the other hand, the position of the first shift lever 804 is fixed, enabling the drill pipe joint on the loading plate to accurately stop at the loading station, so that it can be more convenient and fast to push the drill pipe joint 400 into the automatic chuck in the subsequent process.

[0066] In this solution, the rotary drive mechanism includes a rotary motor 801 connected to the drive assembly 500, a rotary plate 802 connected to the output end of the rotary motor 801, and a connecting rod 803 connecting the rotary plate 802 and the arc plate 813 respectively.

[0067] As an optional embodiment of the present invention, the suction unit includes a push plate 808, a distance adjusting member 809 connected to the push plate 808, and a plurality of first electromagnets 815 installed on the push plate 808. The distance adjusting member 809 is arranged on the rotary plate 802, and the output end of the distance adjusting member 809 movably penetrates through the arc plate 813 and then is connected to the push plate 808. The first electromagnet 815 can magnetically attract the drill pipe joint 400. The distance adjusting member 809 can be an electric push rod or a cylinder. The magnetic force of the first electromagnet 815 is determined according to the magnitude of the input current, and its magnetic force is sufficient to completely adsorb the drill pipe joint 400, so that the end face of the drill pipe joint 400 fits on the surface of the push plate 808.

[0068] In this solution, multiple groups of unloading units are provided. The unloading unit includes a cover plate 806, a magnetic chuck 807, and a telescopic member 810 connecting the cover plate 806 and the magnetic chuck 807. The cover plate 806 is detachably connected to the first shift lever 804 and the second shift lever 805. The magnetic chuck 807 can adsorb on the outer wall of the drill pipe joint 400. Electromagnets two 811 are respectively arranged on the adjacent sides of the cover plate 806 and the magnetic chuck 807, and the two sets of electromagnets two 811 arranged oppositely can be magnetically repelled or attracted to each other.

[0069] This solution provides an unloading unit that can, on the one hand, effectively adsorb the drill pipe joint 400 and facilitate the adjustment of the position of the drill pipe joint 400, and on the other hand, the magnetic chuck 807 with adjustable position can adapt to drill pipe joints of different diameters. At the same time, due to the action of the telescopic member 810 and the electromagnet two 811, the magnetic chuck 807 can be used to push the drill pipe joint onto the unloading rack 700.

[0070] The side of the magnetic chuck 807 in contact with the drill pipe joint 400 is set as a curved surface, and a plurality of holes 814 are provided on the push plate 808. The provision of the holes 814 can enhance the magnetic effect.

[0071] Reference can be made to Figure 8, the driving assembly 500 includes a driving motor 501, a lead screw 502, a connecting frame 504 and a guiding mechanism. The driving motor 501 is installed on the top of the bed body 100. One end of the lead screw 502 is connected to the output end of the driving motor 501, and the other end of the lead screw 502 is rotatably connected to the bed body 100. A threaded hole 505 that is helically engaged with the lead screw 502 is formed in the connecting frame 504. One end of the connecting frame 504 is fixed to the rotating motor 801, and the other end of the connecting frame 504 is slidably connected to the bed body 100 through the guiding mechanism.

[0072] The guiding mechanism includes a hanging rod 506 provided at the end of the connecting frame 504, a guide rail 503 provided on the top of the bed body 100, and a guiding slider 508 that is slidably engaged with the guide rail 503.
