Description

[0002] Oil casing pipes are steel pipes used to support the well walls of oil and gas wells to ensure the progress of the drilling process and the normal operation of the entire oil well after completion. During the processing of oil casing pipes, they need to be cut by a numerically controlled pipe threading lathe.

[0003] A patent application with the publication number CN109822352B discloses a portable casing thread processing device, which includes a device housing, a lifting point, a device rotating part, a turning assembly, and a hydraulic power source system. The device rotating part and the turning assembly include a rotating positioning shaft, a numerically controlled turning assembly, and a numerically controlled threading assembly; the hydraulic power source system includes a hydraulic motor, an external clamping oil cylinder, an internal support oil cylinder, and a mechanical limit cylinder; the device housing is a side-opening frame, the external clamping oil cylinder is horizontally fixed at the end of the frame, the clamping direction is longitudinal, the internal support oil cylinder is horizontally fixed inside the middle of the frame, the clamping direction is longitudinal, and the mechanical limit cylinder is longitudinally fixed on one side of the internal support oil cylinder, and the clamping direction is horizontal; this set of equipment has low requirements for the working environment and can work in the wild; it has a wide processing range, and there is no need to replace the tooling during the specification switching process, saving time and improving work efficiency; during the operation process, the pipe body itself will not rotate, reducing the risk coefficient of the processing operation.

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0022] Example 1: As Figures 1-5 shown, a turning device for stainless steel used in the processing of threaded sleeves according to an embodiment of the present invention includes a ring frame 1. Rectangular sliders 11 are respectively and slidably arranged around the inside of the ring frame 1. Rotating wheels 111 are respectively rotatably arranged at opposite ends of the rectangular sliders 11. The rotating wheels 111 are used for clamping the metal bar stock 7. The ring frame 1 is fixedly connected to the upper end of the base plate 6 through a first support block 14. A cutting assembly is slidably arranged on one side of the ring frame 1. The cutting assembly includes a turning tool 2 arranged on one side of the middle of the ring frame 1. The turning tool 2 is used for turning the inner wall of the metal bar stock 7. An oil application assembly is arranged on the side of the ring frame 1 away from the turning tool 2. The oil application assembly includes a cylindrical tube 5 slidably arranged on one side of the ring frame 1. A second sector block 53 is fixedly connected to one end of the cylindrical tube 5 close to the ring frame 1. The inside of the second sector block 53 is a hollow structure. The second sector block 53 communicates with the inside of the cylindrical tube 5. A plurality of circular holes 531 are arranged on the outer surface of the second sector block 53.

[0023] Specifically, when turning the threads inside the bushing, it is necessary to drive the bushing to rotate. While the bushing is rotating, the cutting tool is driven to penetrate into the bushing, and the cutting tool turns the inside of the bushing. Since the inside of the bushing is turned, heat dissipation is slow, and continuous processing may cause a significant reduction in the service life of the cutting tool. Existing cooling methods generally use water cooling, but it is impossible to directly cool the inside of the bushing, and the cooling effect is poor. When using this turning device, place the metal bar stock 7 between several rotating wheels 111. Then drive the rectangular slider 11 to drive the rotating wheels 111 to slide outward of the metal bar stock 7, so that the rotating wheels 111 are closely attached to the periphery of the metal bar stock 7. Then drive the cylinder 5 to drive the second sector block 53 to slide towards the middle of the metal bar stock 7. The cylinder 5 is connected to the storage tank through an external pipeline and can transport lubricating oil into the cylinder 5. Then drive the cylinder 5 to drive the second sector block 53 to slide into the metal bar stock 7 while the lubricating oil enters the inside of the second sector block 53. Then the lubricating oil flows out from the round hole 531 and is smeared on the inner periphery of the metal bar stock 7. After smearing, drive the rotating wheels 111 to rotate to drive the metal bar stock 7 to rotate. Then drive the turning tool 2 to slide into the metal bar stock 7 to turn the inside of the metal bar stock 7. By driving the cylinder 5 to drive the second sector block 53 to smear lubricating oil on the inside of the metal bar stock 7, and then driving the turning tool 2 to turn the inside of the metal bar stock 7, the lubricating oil can form a lubricating film between the metal bar stock 7 and the turning tool 2, reduce the friction of the contact surface, thereby reducing wear, and at the same time can also reduce the heat generated during turning, thereby extending the service life of the tool and the workpiece.

[0024] As Figure 5 shown, a first sector block 52 is provided on one side of the second sector block 53 close to the ring frame 1, and the first sector block 52 is fixedly connected to the outside of the cylinder 5.

[0025] Specifically, when smearing lubricating oil on the inside of the metal bar stock 7, drive the cylinder 5 to drive the second sector block 53 and the first sector block 52 to slide into the metal bar stock 7. The first sector block 52 pushes the impurities inside the metal bar stock 7 to one side until the impurities are pushed out. Then drive the cylinder 5 to drive the second sector block 53 to slide in the opposite direction and smear the lubricating oil on the inside of the metal bar stock 7. By driving the cylinder 5 to drive the first sector block 52 to scrape the impurities inside the metal bar stock 7, and then driving the second sector block 53 to slide inside the metal bar stock 7 and smear the lubricating oil, ensure that there are no impurities inside the metal bar stock 7, and reduce the possibility of damage to the turning tool 2 during turning.

[0026] As Figures 4-5As shown in the figure, a first circular plate 3 is provided on one side of the circular ring frame 1. The cylinder 5 is slidably arranged in the middle of the first circular plate 3. Clamping blocks 31 are slidably arranged around the side of the first circular plate 3 close to the circular ring frame 1. Convex blocks 311 are fixedly connected to the opposite sides of several clamping blocks 31 respectively. The first circular plate 3 is fixedly connected to the upper end of the bottom plate 6 through a third support block 312.

[0027] Specifically, after the metal rod 7 is clamped by the runner 111, then the clamping blocks 31 are driven to slide outward to the metal rod 7, and the convex blocks 311 are located at one end of the metal rod 7 away from the turning tool 2. The convex blocks 311 abut against one end of the metal rod 7 away from the turning tool 2, further fixing the metal rod 7 to prevent the metal rod 7 from shaking during the turning process.

[0028] As Figure 4 shown in the figure, a second circular plate 33 is fixedly connected to the outer side of the middle of the cylinder 5. The second circular plate 33 is slidably arranged on the upper end of the second slide rail 35 through a fourth support block 331. The second slide rail 35 is fixedly connected to the upper end of the bottom plate 6. A second cylindrical rod 51 is slidably arranged inside one end of the cylinder 5 away from the first circular plate 3. A hose 54 is fixedly connected to the upper end of the middle of the cylinder 5. The hose 54 is communicated with the inside of the cylinder 5. A third circular plate 34 is fixedly connected to one end of the second cylindrical rod 51 away from the cylinder 5. The third circular plate 34 is fixedly connected to the upper end of the bottom plate 6 through a fifth support block 341.

[0029] Specifically, by driving the fourth support block 331 to drive the second circular plate 33 to slide to one side on the upper end of the second slide rail 35, the second circular plate 33 drives the first sector block 52 and the second sector block 53 to slide into the metal rod 7 through the cylinder 5. At the same time, the cylinder 5 slides to the side away from the third circular plate 34 on the outside of the second cylindrical rod 51. One end of the hose 54 away from the cylinder 5 is connected to a storage tank, and the storage tank is filled with lubricating oil. When the cylinder 5 slides, the lubricating oil in the storage tank is sucked into the cylinder 5 through the hose 54. Then, the cylinder 5 is driven to drive the first sector block 52 and the second sector block 53 to slide to the side close to the third circular plate 34, so that the lubricating oil inside the cylinder 5 is extruded through the circular hole 531 and smeared on the inside of the metal rod 7 during the sliding.

[0030] As Figure 2 shown in the figure, cylindrical blocks 112 are fixedly connected to both sides of the rectangular slider 11. Circular rings 12 are fixedly connected to both sides inside the circular ring frame 1. Rectangular holes 121 are respectively opened at the positions of the circular rings 12 corresponding to the cylindrical blocks 112. The cylindrical blocks 112 can slide inside the rectangular holes 121. A gear ring 13 is rotatably arranged on one side inside the circular ring frame 1. Arc-shaped holes 131 are respectively opened at the positions of the gear ring 13 corresponding to the cylindrical blocks 112. The cylindrical blocks 112 can slide inside the arc-shaped holes 131. A gear 15 is engaged with the lower end of the gear ring 13. The gear 15 is rotatably arranged on one side of the first support block 14.

[0031] Specifically, the gear 15 can be driven by a motor. When clamping the metal rod 7, the motor is started to drive the gear 15 to rotate. The gear 15 drives the gear ring 13 to rotate. While the gear ring 13 rotates, a plurality of cylindrical blocks 112 slide in the arc-shaped holes 131 at the same time, and at the same time, the cylindrical blocks 112 slide in the rectangular holes 121. The cylindrical blocks 112 drive the rectangular slider 11 to move towards the metal rod 7 at the same time. The rectangular slider 11 drives the runner 111 to closely adhere to the periphery of the metal rod 7, and then the metal rod 7 can be clamped.

[0032] As Figure 3 shown, inside the mounting seat 21 provided outside the turning tool 2, a first bolt 211 is installed at the upper end of the mounting seat 21. The mounting seat 21 is fixedly connected to the upper end of the second support block 23 through the first fixing block 22. The second support block 23 is slidably arranged at the upper end of the first slide rail 24, and the first slide rail 24 is fixedly connected to the upper end of the bottom plate 6.

[0033] Specifically, by driving the first bolt 211 to rotate, the first bolt 211 is moved away from the turning tool 2, and then the turning tool 2 can be taken out of the mounting seat 21. Different sizes of turning tools 2 can be replaced according to the size of the metal rod 7 to be machined. After the turning tool 2 is installed inside the mounting seat 21, the first bolt 211 is driven to rotate until the first bolt 211 abuts against the turning tool 2, and the turning tool 2 can be fixed inside the mounting seat 21. By driving the second support block 23 to slide on the upper end of the first slide rail 24 towards the side of the metal rod 7, the turning tool 2 is driven by the mounting seat 21 to move towards the middle of the metal rod 7, and turning work is carried out inside the metal rod 7.

[0034] Embodiment 2: As Figure 6 shown, compared with Embodiment 1, another implementation manner of the present invention is that a chamfering component is provided on one side of the circular ring frame 1 close to the turning tool 2. The chamfering component includes two bevel blocks 4 slidably arranged on one side of the circular ring frame 1.

[0035] Specifically, the edge of the metal rod 7 is a sharp right angle and needs to be chamfered. Chamfering can remove the burrs and acute angles at the edge of the metal rod 7, make the edge smoother, reduce the burrs generated by machining, and avoid cutting the user. Chamfering can improve the assembly accuracy and reliability. Chamfering can make the metal rod 7 easier to assemble, reduce the resistance during assembly, and improve the overall stability and durability. The metal rod 7 is driven to rotate, and then the two bevel blocks 4 are driven to move towards the side close to the metal rod 7, so that the hypotenuse where the bevel blocks 4 are located contacts the edge of the metal rod 7, and then the sharp edge of the metal rod 7 can be polished to make the edge smoother. As Figure 7As shown, U-shaped blocks 41 are fixedly connected to one side of the bevel blocks 4 respectively. Third rectangular blocks 42 are rotatably arranged in the middle parts of the U-shaped blocks 41 respectively. The third rectangular blocks 42 are slidably arranged in the middle parts of the U-shaped plates 44 respectively. Fourth rectangular blocks 43 are fixedly connected to one side of the third rectangular blocks 42 respectively. The fourth rectangular blocks 43 respectively slide through the middle parts of the U-shaped plates 44. A bidirectional lead screw 431 is commonly threadedly connected to the middle parts of the fourth rectangular blocks 43. Both ends of the bidirectional lead screw 431 are rotatably connected to fifth rectangular blocks 432, and the fifth rectangular blocks 432 are fixedly connected to one side of the U-shaped plates 44.

[0036] Specifically, by driving the bidirectional lead screw 431 to rotate, the fourth rectangular blocks 43 are driven to move towards both sides. The fourth rectangular blocks 43 drive the bevel blocks 4 on both sides to move towards both sides simultaneously through the third rectangular blocks 42. By adjusting the distance between the two bevel blocks 4, the edges of metal bar stocks 7 of different sizes can be polished.

[0037] As Figures 7-8 shown, first rectangular bars 411 are rotatably connected to both sides of the U-shaped blocks 41 respectively. Second rectangular bars 412 are slidably arranged inside the ends of the first rectangular bars 411 far from the U-shaped blocks 41 respectively. A cylindrical bar 416 is commonly fixedly connected to the middle parts of one ends of two opposite second rectangular bars 412. The cylindrical bar 416 is rotatably arranged in the middle part of the second rectangular block 417. A second bolt 4171 is installed at the upper end of the second rectangular block 417. The second rectangular block 417 is slidably arranged on one side of the U-shaped plate 44. Third rectangular bars 413 are rotatably arranged on both sides of the cylindrical bar 416 respectively. The third rectangular bars 413 rotate on one side of the second rectangular bars 412 respectively. The opposite ends of the two third rectangular bars 413 are commonly slidably arranged inside both ends of the first rectangular cylinder 414. The first rectangular cylinder 414 is fixedly connected to one side of the U-shaped plate 44 through a first rectangular block 415.

[0038] Specifically, by simultaneously driving the two cylindrical bars 416 to rotate, the two groups of second rectangular bars 412 are driven to rotate. The second rectangular bars 412 drive the U-shaped blocks 41 to rotate at one end of the third rectangular blocks 42 through the first rectangular bars 411. The second rectangular bars 412 slide inside the first rectangular bars 411 at the same time, and the angle of the bevel block 4 can be adjusted. The chamfers of different angles of the metal bar stock 7 can be polished. After the adjustment is completed, driving the second bolt 4171 to rotate to abut against the cylindrical bar 416 can fix the adjusted angle of the bevel block 4. When adjusting the distance between the two bevel blocks 4, the third rectangular block 42 drives the first rectangular bar 411 to move through the U-shaped block 41. The first rectangular bar 411 drives the third rectangular bar 413 to slide inside the first rectangular cylinder 414 through the second rectangular bar 412, and at the same time drives the second rectangular block 417 to slide on one side of the U-shaped plate 44, so that the angle of the bevel block 4 can remain unchanged.

[0039] As Figure 6As shown, rectangular plates 45 are fixedly connected to both sides of the U-shaped plate 44. Fourth rectangular bars 451 are fixedly connected to the lower ends of the rectangular plates 45. The lower ends of the fourth rectangular bars 451 are slidably arranged inside second rectangular cylinders 452. The second rectangular cylinders 452 are slidably arranged on the upper ends of third slide rails 453. The third slide rails 453 are fixedly connected to the upper end of the base plate 6.

[0040] Specifically, after adjusting the distance between the two bevel blocks 4, by driving the fourth rectangular bar 451 to slide inside the second rectangular cylinder 452, the fourth rectangular bar 451 adjusts the height of the U-shaped plate 44 through the rectangular plate 45, and at the same time adjusts the height of the bevel block 4, so that the bevel blocks 4 are respectively located at the edges of the metal bar stock 7. Subsequently, drive the second rectangular cylinder 452 to slide on the third slide rail 453 towards the metal bar stock 7, drive the bevel block 4 to contact the edge of the metal bar stock 7, and then the edge of the metal bar stock 7 can be polished.

[0041] Working principle: During processing, place the metal bar stock 7 between several runner wheels 111. Start the motor to drive the gear 15 to rotate. The gear 15 drives the gear ring 13 to rotate. While the gear ring 13 rotates, it drives several cylindrical blocks 112 to slide inside the arc-shaped holes 131 at the same time, and at the same time makes the cylindrical blocks 112 slide inside the rectangular holes 121. The cylindrical blocks 112 drive the rectangular sliders 11 to move towards the metal bar stock 7 at the same time. The rectangular sliders 11 drive the runner wheels 111 to closely adhere to the periphery of the metal bar stock 7, and then the metal bar stock 7 can be clamped. Subsequently, drive the clamping block 31 to slide towards the outside of the metal bar stock 7, and make the convex block 311 located at one end of the metal bar stock 7 away from the turning tool 2. The convex block 311 abuts against one end of the metal bar stock 7 away from the turning tool 2 to further fix the metal bar stock 7; Subsequently, drive the cylinder 5 to drive the second sector block 53 and the first sector block 52 to slide into the metal bar stock 7. The first sector block 52 pushes the impurities inside the metal bar stock 7 to one side until the impurities are pushed out. Subsequently, drive the cylinder 5 to drive the second sector block 53 to slide in the opposite direction, and apply lubricating oil to the inside of the metal bar stock 7. Drive the cylinder 5 to drive the first sector block 52 to scrape the impurities inside the metal bar stock 7. Then drive the second sector block 53 to slide inside the metal bar stock 7 and apply lubricating oil. Drive the second support block 23 to slide on the upper end of the first slide rail 24 towards the metal bar stock 7, and drive the turning tool 2 to move towards the middle of the metal bar stock 7 through the mounting seat 21 to perform turning work on the inside of the metal bar stock 7; By driving the fourth rectangular bar 451 to slide inside the second rectangular cylinder 452, the fourth rectangular bar 451 adjusts the height of the U-shaped plate 44 through the rectangular plate 45, and at the same time adjusts the height of the bevel block 4, so that the bevel blocks 4 are respectively located at the edges of the metal bar stock 7. Subsequently, drive the second rectangular cylinder 452 to slide on the third slide rail 453 towards the metal bar stock 7, drive the bevel block 4 to contact the edge of the metal bar stock 7, and then the edge of the metal bar stock 7 can be polished.
