Detailed implementation manners

[0026] Next, in combination with the accompanying drawings and specific implementation manners, 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.

[0027] Embodiment 1 Please refer to Figures 1 - 12 , A thread processing device for manufacturing a drill pipe joint for ultra-deep wells 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 installed with tools for turning threads, and the tool rest support 301 can control the position of the tool rest 300 to work automatically.

[0028] In order to adapt to the existing thread processing lathe, a notch one 101 and a notch two 102 (refer to Figure 7 ) can be opened on one side of the bed body 100. 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.

[0029] The loading rack 600 includes a bearing plate 602 and a loading plate 601. A plurality of drill pipe joints 400 that can roll are arranged in an orderly manner on the bearing plate 602. It passes through the notch one 101 and is rotatably connected to the inner wall of the notch one 101, and: when the bearing plate 602 is rotated to the lowest end near the loading plate 601, the drill pipe joint 400 at the front moves onto the loading plate 601, while the remaining drill pipe joints 400 still remain on the bearing plate 602; this can ensure that only one drill pipe joint 400 moves onto the loading plate 601 each time for loading, facilitating orderly processing without manual loading.

[0030] In order to improve work efficiency and facilitate the automatic transfer of the processed drill pipe joint 400, the unloading rack 700 is passed through the notch two 102; In this solution, the auxiliary loading and unloading assembly 800 includes a material blocking unit, a material suction unit, and a material unloading unit. Among them, the material blocking unit is used to block the drill pipe joint 400 on the loading plate 601 and make the drill pipe joint 400 coaxial with the automatic chuck 200. The material suction unit drives the drill pipe joint 400 to be loaded and unloaded in the automatic chuck 200. The material unloading unit is used to push the processed drill pipe joint 400 to move to the unloading rack 700; The driving assembly 500 is used to drive the auxiliary loading and unloading assembly 800 to move.

[0031] This embodiment is combined with reference to Figures 1 - 4 , and the processing steps are roughly as follows: Refer to Figure 1 , first, a plurality of drill pipe joints 400 to be processed are orderly placed on the bearing plate 602. It is necessary to make the material blocking unit above the loading plate 601, and then rotate the bearing plate 602 so that one end close to the loading plate 601 is the lowest. After the drill pipe joint 400 at the front moves to the loading plate 601, it is blocked by the material blocking unit and stops at the loading station; Refer to Figure 2 , immediately afterwards, the material suction unit works, and can push the drill pipe joint 400 from one side into the automatic chuck 200. The automatic chuck 200 automatically clamps the drill pipe joint, and then rotates the bearing plate 602 in the reverse direction so that the remaining drill pipe joints will not move towards the direction close to the automatic chuck 200. At the same time, adjust the position of the material blocking mechanism to a suitable position to avoid interfering with the turning work. Finally, install the tool, adjust the position of the tool rest, and turn the thread; Refer to Figure 3 , for the drill pipe joint that has completed turning, it is taken out of the automatic chuck 200 under the drive of the material suction unit, and then the driving assembly 500 works, driving the entire auxiliary loading and unloading assembly to move towards the side of the unloading rack 700 to Figure 3 the position shown; Refer to Figure 4 , adjust the position of the material blocking unit so that the material unloading unit is below the drill pipe joint, and use the driving force of the material unloading unit to automatically push the drill pipe joint 400 onto the unloading rack 700.

[0032] In this solution, guardrails 603 are provided on all sides of the bearing plate 602 except for 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, and the servo motor is used to drive the rotating shaft to rotate, thereby driving the bearing plate 602 to rotate.

[0033] 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 first notch 101 and is connected to an end plate 610. A vertical power component 606 is installed in the first notch 101, and a horizontal power component 607 is installed outside the first notch 101. The output end of the horizontal power component 607 and the end plate 610 are slidably connected in the vertical direction. Specifically, a first movable block 608 is slidably installed vertically on the inner side of the end plate 610. The output end of the horizontal power component 607 is connected to the first movable block 608, and the output end of the vertical power component 606 and the cross beam 605 are slidably connected in the horizontal direction. Specifically, a second movable block 611 is fixed to the output end of the vertical power component 606, and the second movable block 611 and the bottom surface of the cross beam 605 are slidably connected. During specific operation, both the vertical power component 606 and the horizontal power component 607 can adopt electric push rods or cylinders.

[0034] Through the above structure, the horizontal position and the 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.

[0035] 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 selected as 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 arranged at both ends of the arc-shaped plate 813, and positioning holes for connecting with the fixing bolts 812 are opened on the first blocking rod 804 and the second blocking rod 805.

[0036] It can be referred to Figure 1 、 Figure 2 and Figure 12 , The positions of the first blocking rod 804 and the second blocking rod 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 blocking rod 804 is fixed, which can enable the drill pipe joint on the loading plate to accurately stay at the loading station, making it more convenient and fast to push the drill pipe joint 400 into the automatic chuck in the subsequent process.

[0037] In this solution, the rotation driving mechanism includes a rotation motor 801 connected to the driving component 500, a rotation plate 802 connected to the output end of the rotation motor 801, and a connecting rod 803 respectively connecting the rotation plate 802 and the arc-shaped plate 813.

[0038] As an optional embodiment of the present invention, the material suction unit includes a push plate 808, a distance adjusting member 809 connected to the push plate 808, and a plurality of electromagnets 815 mounted on the push plate 808. The distance adjusting member 809 is disposed on the rotating plate 802. The output end of the distance adjusting member 809 movably penetrates through the arc-shaped plate 813 and then is connected to the push plate 808. The 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 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.

[0039] In this solution, multiple groups of blanking units are provided. The blanking 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 stop rod 804 and the second stop rod 805. The magnetic chuck 807 can adsorb on the outer wall of the drill pipe joint 400. Electromagnets 811 are respectively arranged on the adjacent sides of the cover plate 806 and the magnetic chuck 807, and the two groups of electromagnets 811 arranged oppositely can be magnetically repelled or attracted to each other.

[0040] This solution provides a blanking unit that can effectively adsorb the drill pipe joint 400 on the one hand, facilitating the adjustment of the position of the drill pipe joint 400, and on the other hand, the telescopic magnetic chuck 807 that can be adjusted in 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 811, the magnetic chuck 807 can be used to push the drill pipe joint onto the blanking rack 700.

[0041] 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 formed on the push plate 808. The formation of the holes 814 can enhance the magnetic effect.

[0042] For reference, Figure 8 As shown, 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 on 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.

[0043] The guiding mechanism includes a hanging rod 506 provided at the end of the connecting frame 504, a guide rail 503 provided at the top of the bed body 100, and a guiding slider 508 that is slidably engaged with the guide rail 503. Among them, a connecting bolt 507 is installed at the top of the hanging rod 506, and the end of the connecting bolt 507 is screwed to the guiding slider 508. A convex block 509 is provided in the middle of the hanging rod 506, and a guide groove that is slidably engaged with the convex block 509 is provided on the outer side of the top of the bed body 100.

[0044] In the present invention, the loading rack 600 is designed to push the drill pipe joints to be processed to the loading station in the auxiliary loading and unloading assembly one by one. Then, the auxiliary loading and unloading assembly can automatically complete the loading, unloading, and transfer work of the drill pipe joints. The auxiliary loading and unloading assembly, the loading rack 600, and the unloading rack 700 designed in the present invention can be adapted to most of the existing CNC lathes on the market. With a little modification, the working efficiency of the lathe can be greatly improved, and the degree of automation can be further enhanced.

[0045] The above-mentioned implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the scope of protection of the present invention.
