Description

Technical Field

[0001] This invention relates to the field of workpiece turning technology, and more specifically to a turning device for producing steel pipe rods. Background Technology

[0002] In the fields of power and telecommunications infrastructure, steel pipe poles are widely used for erecting lines or supporting equipment due to their high structural strength and convenient installation. During the production of steel pipe poles, turning is a core process to ensure the precision of key components (such as flanges, socket joints, and threaded journals). The dimensional and positional accuracy of these components directly determines the coaxiality, connection sealing, and overall structural stability of the assembled steel pipe pole sections. Especially for socket-jointed steel pipe poles, the inner and outer conical surfaces of the sleeve joint need to be turned. Turning the outer conical surface at the end of the pole body ensures that it connects with the other section... The inner conical surface of the steel pipe fits tightly, improving the connection sealing and pull-out resistance. The turning device of the steel pipe rod mostly adopts the method of internal support to maintain a rigid connection between it and the steel pipe rod, so as to maintain a stable state between the steel pipe rod and the turning. Although the inside of the steel pipe rod is rigidly supported, the cutting heat generated during the turning of the steel pipe rod cannot be conducted and discharged in time. It is easy to form heat accumulation inside the steel pipe rod, causing the steel pipe rod to expand due to heat and be forcibly constrained by the support, resulting in deformation of the steel pipe rod. This leads to insufficient fit of the conical surface of the socket and significantly reduces the overall production efficiency of the steel pipe rod. Summary of the Invention

[0003] The purpose of this invention is to provide a turning apparatus for producing steel pipe poles, so as to solve the above-mentioned shortcomings in the technology.

One side of the mounting plate is equipped with an adapter component that pushes several stabilizing frames to be synchronized with the interior of the steel pipe pole body; The stabilizer frame has a segmented assembly inside that extends the contact surface between the distributed support and the main body of the steel pipe pole; The mounting plate is equipped with an elastic preload assembly that elastically preloads the steel pipe pole body and the stabilizer frame. The turning machine frame is equipped with a rotating assembly, which is used to drive the mounting frame to rotate. During the rotation of the mounting frame driven by the rotating assembly, the main body of the steel pipe rod maintains a roller connection with the bottom support.

One end of the movable cylinder is provided with an offset component that drives the centering cone to adjust eccentrically along the inside of the steel pipe rod body.

[0006] Preferably, a limiting rod is fixedly connected to one end of the stabilizer near the mounting plate, and a limiting groove is provided on one side of the mounting plate to guide the movement of the limiting rod.

[0007] Preferably, the offset assembly includes an offset plate bolted to one end of the movable cylinder and a mounting plate fixedly connected to one end of the offset plate, and the centering cone is a conical structure. A slider is fixedly connected to one end of the centering cone. A groove is provided on one side of the mounting plate for guiding the slider to move. A threaded hole communicating with the inside of the mounting plate is provided on the outside of the mounting plate. An adjusting bolt is screwed into the inside of the threaded hole, and one end of the adjusting bolt located inside the slide groove is movably connected to the top of the slider.

[0008] Preferably, the segmented assembly includes a second electric push rod fixedly connected to the bottom end of the stabilizer frame, two symmetrical segmented supports are slidably connected to the top of the stabilizer frame, and the two segmented supports are sloped to the two ends of the distributed support. The telescopic end of the second electric push rod extends into the interior of the stabilizer frame and is fixedly connected to a displacement plate. A displacement shaft is installed on one side of each of the two segmented supports, and a diagonal support rod is connected between the two displacement shafts and the displacement plate.

[0009] Preferably, the elastic pre-tightening assembly includes an abutment groove fixedly connected to one end of the mounting plate, a plurality of elastic cone pads fixedly connected to one end of the abutment groove, a plurality of expansion joints being provided on one end of the flexible plate near the plurality of elastic cone pads, an inner screw cylinder being fixedly connected to one end of the elastic cone pads, and a floating distance existing between the inner screw cylinder and the flexible plate, an outer screw ring being screwed to one end of the inner screw cylinder, and an abutment groove being provided inside the outer screw ring to cooperate with the plurality of elastic cone pads.

[0010] Preferably, the rotating assembly includes a servo motor fixedly connected inside the turning machine frame. The output end of the servo motor and one end of the mounting frame are both equipped with pulleys. A belt strip is sleeved on the outside of the two pulleys. Two symmetrical auxiliary rollers are installed at the top of the bottom bracket, and the outside of the two auxiliary rollers is in contact with the outside of the steel pipe rod body. The servo motor and the base bracket are connected together by a co-directional component that drives the auxiliary roller to rotate.

[0011] Preferably, the co-directional assembly includes a rotating column installed between the servo motor and the base bracket. One end of the auxiliary roller is fixedly connected to a concentric column, which is rotatably connected inside the base bracket. A transmission belt is sleeved between the rotating column and the concentric column, and the transmission belt is located inside the base bracket.

[0012] The technical effects and advantages provided by the present invention in the above technical solution are as follows: This invention employs a multi-point contact design between the stabilizer and the main body of the steel pipe pole. This design allows for simultaneous multi-point support of the steel pipe pole body by the distributed supports, effectively preventing the stabilizer from directly covering a large area inside the steel pipe pole body and avoiding large-area obstruction of the heat dissipation surface. This leaves space for subsequent heat dissipation. Furthermore, the multi-point supported stabilizer has a hollow support form inside the steel pipe pole body, significantly reducing the contact area with the inside of the pole body. This does not affect the stability of the support and further reduces obstruction to the heat dissipation path. At the same time, the machining heat generated during the machining of the steel pipe pole body can be smoothly discharged through the drainage channel at the top of the distributed supports, effectively avoiding local overheating caused by the accumulation of machining heat and ultimately ensuring the integrity of the machining process of the steel pipe pole body. This invention uses an arc-shaped structure for the distributed support, which allows the distributed support to adapt to the irregular shape of the inner wall of the steel pipe pole body. This enables the distributed support to form a ring-shaped contact with the inner wall of the steel pipe pole body, while still ensuring contact in most areas. This reduces blind spots in the support, improves the stability between the steel pipe pole body and the main body, reduces machining vibration and displacement, ensures the stability of the machining datum, and further improves the machining accuracy of the steel pipe pole body. This invention, through the setting of distributed supports, support diagonal rods, and stabilizing rods, enables the adjustment of the fit between the distributed supports and the interior of the steel pipe pole body. The distributed supports can naturally fit with the curved surface of the inner wall of the steel pipe pole body, forming a large-area arc-shaped contact. The support pressure can be evenly distributed over a larger area, reducing the squeezing damage of the supports to the inner wall of the steel pipe pole body and protecting the processing quality of the steel pipe pole body. This invention supports the weight of the steel pipe rod body by using a base bracket to prevent sagging due to its own length or weight, avoids the steel pipe rod body from shaking and failing to align with the installation position when being installed in the stabilizer, and restricts the horizontal displacement of the steel pipe rod body by the centering cone, keeping it on the preset installation path, thus laying the foundation for stable support during subsequent turning. This invention uses the movement of two inclined supports to drive two segmented supports to move outward synchronously and separate along both ends of the dispersed support. After separation, the two segmented supports and the mounting plate naturally form a segmented support structure with intervals, so that when the segmented supports and the mounting plate come into contact with the inner wall of the steel pipe rod body, there are gaps between them. This prevents the inner wall of the steel pipe rod body from being covered in a large area, and ensures that the cutting heat can be discharged through the gaps, avoiding the impact of thermal damage on the processing, and further improving the turning quality of the steel pipe rod body. This invention, through the arrangement of an elastic conical pad, an external threaded ring frame, a steel pipe rod body, and a stabilizing frame, provides a continuous preload force through the elasticity of the elastic conical pad itself, which closely fits the contact surface between the port and the support body. Even when subjected to centrifugal force or cutting force impact, the gap can be offset by deformation, and the two can always maintain a tight connection, avoiding workpiece vibration or axis offset caused by support loosening, and providing a stable reference for subsequent high-precision turning. This invention, through the arrangement of a rotating column, a concentric column, and a steel pipe rod body, achieves a rolling contact of the rotating column that is a line contact rather than a surface contact. This results in a small contact area and dispersed pressure. Simultaneously, the contact point changes continuously during the rolling process, preventing prolonged compression of the same position. This provides stable radial constraint, preventing radial displacement due to centrifugal force or cutting force, and effectively avoids deformation of thin-walled parts of the steel pipe rod body due to long-term localized pressure. This leads to smoother turning feed and further optimizes the surface quality of the machined material. Attached Figure Description

The turning frame 1 is equipped with a base bracket 25 and a centering cone 26, and the steel pipe rod body 12 is in precise contact with the stabilizing frames 23 through the base bracket 25 and the centering cone 26. The number of the several stabilizing frames 23 is three, and the three stabilizing frames 23 are arranged in a circular array around one end of the mounting plate 22, so that the three stabilizing frames 23 are used to provide multi-point support inside the steel pipe rod body 12.

One end of the moving cylinder 33 is provided with an offset component 6 that drives the centering cone 26 to adjust eccentrically along the inside of the steel pipe rod body 12. refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the offset assembly 6 includes an offset plate 61 bolted to one end of the movable cylinder 33 and a mounting plate 62 fixedly connected to one end of the offset plate 61. The centering cone 26 is a conical structure. A slider 64 is fixedly connected to one end of the centering cone 26. A groove 63 is provided on one side of the mounting plate 62 for guiding the slider 64 to move. A threaded hole 65 communicating with the interior is provided on the outside of the mounting plate 62. An adjusting bolt 66 is screwed into the inside of the threaded hole 65, and one end of the adjusting bolt 66 located inside the slide groove 63 is movably connected to the top of the slider 64. refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the movable cylinder 33 is slidably sleeved on the outside of the centering rod 31, so that the movable cylinder 33 can move along the external guide of the centering rod 31. The number of stabilizing rods 34, limiting grooves 38 and limiting rods 37 is the same as that of the stabilizing frame 23. There are two centering shafts 36 and two supporting inclined rods 35 between each stabilizing frame 23 and the stabilizing rod 34. The centering cone 26 is set as a conical structure and is set at the front end of the mounting plate 22, so that the steel pipe rod body 12 can be automatically centered when installed, reducing the number of adjustments to the steel pipe rod body 12.

[0019] refer to Figure 3 , Figure 4 and Figure 5 As shown, the interior of the stabilizer 23 is provided with a segmented assembly 4 that extends the contact surface between the distributed support 24 and the main body 12 of the steel pipe rod. The segmented assembly 4 includes a second electric push rod 41 fixedly connected to the bottom of the stabilizer 23. Two symmetrical segmented supports 44 are slidably connected to the top of the stabilizer 23, and the two segmented supports 44 and the two ends of the distributed support 24 are sloped together. The telescopic end of the second electric push rod 41 extends into the interior of the stabilizer 23 and is fixedly connected to a displacement plate 42. A displacement shaft column 45 is installed on one side of each of the two segmented supports 44, and the two displacement shaft columns 45 and the displacement plate 42 are connected together by an inclined support rod 43. The structure of the segmented supports 44 is the same as the number of distributed supports 24.

[0020] refer to Figure 2 and Figure 6 As shown, the outside of the mounting plate 22 is provided with an elastic pre-tightening component 5 for elastically pre-tightening the steel pipe rod body 12 and the stabilizer 23. The elastic pre-tightening component 5 includes an abutment groove 55 fixedly connected to one end of the mounting plate 22. A plurality of elastic cone pads 52 are fixedly connected to one end of the abutment groove 55. A plurality of expansion joints 56 are opened at one end of the flexible plate 51 near the plurality of elastic cone pads 52. An inner screw cylinder 53 is fixedly connected to one end of the elastic cone pads 52, and there is a floating distance between the inner screw cylinder 53 and the flexible plate 51. An outer screw ring frame 54 is screwed to one end of the inner screw cylinder 53. An abutment groove 55 that cooperates with the plurality of elastic cone pads 52 is opened inside the outer screw ring frame 54. Furthermore, the flexible plate 51 is separated by the expansion joint 56, and the expansion joint 56 provides a floating gap for the movement of the flexible plate 51 and the elastic cone pad 52. The elastic cone pad 52 is made of elastic material. In addition, the movement of the elastic cone pad 52 causes the flexible plate 51 connected to it to move synchronously, and the flexible plate 51 only swings slightly, while the rest remains stably connected to the mounting plate 22.

[0021] refer to Figure 2 and Figure 8 As shown, the turning frame 1 is equipped with a rotating assembly 7, which is used to drive the mounting frame 21 to rotate. During the rotation of the mounting frame 21 driven by the rotating assembly 7, the main body 12 of the steel pipe rod maintains a roller connection with the bottom support frame 25. The rotating assembly 7 includes a servo motor 71 fixedly connected inside the turning frame 1. The output end of the servo motor 71 and one end of the mounting frame 21 are both equipped with pulleys 73. The two pulleys 73 are connected to the outside of a belt strip 72. The top of the bottom support frame 25 is equipped with two symmetrical auxiliary rollers 74, and the outside of the two auxiliary rollers 74 is in contact with the outside of the main body 12 of the steel pipe rod. The servo motor 71 and the base bracket 25 are connected together by a co-directional component that drives the auxiliary roller 74 to rotate; refer to Figure 2 and Figure 8 As shown, the co-rotating assembly includes a rotating column 77 installed between the servo motor 71 and the base bracket 25. One end of the auxiliary roller 74 is fixedly connected to a concentric column 75, and the concentric column 75 is rotatably connected inside the base bracket 25. A transmission belt 76 is sleeved between the rotating column 77 and the concentric column 75, and the transmission belt 76 is located inside the base bracket 25. The number of concentric columns 75 and transmission belts 76 is the same as that of the auxiliary roller 74, and the two transmission belts 76 are symmetrically arranged outside the rotating column 77. Thus, the rotation of the rotating column 77 drives the two transmission belts 76 to drive the two concentric columns 75 and the auxiliary roller 74 to rotate inside the base bracket 25. In addition, one end of another pulley 73 extends into the interior of the mounting bracket 21 and is installed at one end of the mounting plate 22.

[0022] Working principle: When using; refer to Figure 3 , Figure 4 and Figure 5 As shown, when it is necessary to achieve multi-segment contact between the distributed support 24 and the interior of the steel pipe rod body 12, the second electric push rod 41 is first driven to extend its telescopic end upward along the interior of the stabilizer 23, which simultaneously drives the displacement plate 42 to slide upward along the interior of the stabilizer 23. When the displacement plate 42 moves, it further links the two inclined supports 43 to move upward synchronously. During the upward movement of the inclined supports 43, the angle between them and the displacement plate 42 changes accordingly, and the tilt posture between the displacement plate 42 and the segmented support 44 is also adjusted synchronously. As the posture of the inclined supports 43 continues to adjust, its inner side gradually comes into contact with the outer wall of the two displacement shaft columns 45, and generates thrust to push the two segmented supports 44 to slide relative to each other along the top of the stabilizer 23. During this process, the two segmented supports 44 gradually separate along both ends of the distributed support 24, and finally the distributed support 24 and the two segmented supports 44 together form multi-segment contact with the interior of the steel pipe rod body 12, providing more uniform and stable support for subsequent turning operations. refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, when it is necessary to adjust the eccentric position between the centering cone 26 and the steel pipe rod body 12, first rotate the adjusting bolt 66 to make it engage with the threaded hole 65. As the adjusting bolt 66 rotates, it will move upward along the inside of the slide groove 63 and the threaded hole 65, and at the same time drive the slider 64 to slide upward synchronously along the inside of the slide groove 63. During the movement of the slider 64, it will move the centering cone 26 synchronously upward along one side of the mounting plate 62, thereby realizing the adjustment of the eccentric position of the centering cone 26 along one side of the mounting plate 62. After the adjustment is completed, the distance between the centering cone 26 and the inner wall of the steel pipe rod body 12 will be matched synchronously, which can effectively avoid the steel pipe rod body 12 from having a hard collision with the centering cone 26 during the installation process. This can ensure that the supporting role of the base bracket 25 and the guiding role of the centering cone 26 work together to provide a clear and stable installation path guide for the steel pipe rod body 12, reduce the jamming and adjustment time during the installation process, and further improve the efficiency of the subsequent turning operation of the steel pipe rod body 12. refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, when machining the steel pipe pole body 12 is required, the steel pipe pole body 12 is first placed on top of the base bracket 25 to provide pre-support for the steel pipe pole body 12, laying a stable foundation for subsequent movement and positioning. Then, the steel pipe pole body 12 is pushed towards one end of the mounting plate 22. During the movement, the interior of the steel pipe pole body 12 passes through the outside of the centering cone 26. With the guidance of the centering cone 26, the steel pipe pole body 12 moves smoothly towards the mounting plate 22, avoiding deviation. As the steel pipe pole body 12 continues to move, its interior gradually approaches the top of the three distributed supports 24. The steel pipe pole body 12 is pushed further until it abuts against one end of the mounting plate 22. At this point, the three stabilizing frames 23 and the three distributed supports 24 are activated simultaneously, providing multi-point support to key positions inside the steel pipe pole body 12, further enhancing its stability. If adjustment of the fit between the distributed supports 24 and the interior of the steel pipe pole body 12 is required... The first electric push rod 32 can be driven to retract its telescopic end, thereby driving the moving cylinder 33 to move along the outer guide of the centering rod 31. When the moving cylinder 33 moves, it will simultaneously drive the stabilizing rod 34, which in turn will move the two supporting inclined rods 35. During this process, the inside of the two supporting inclined rods 35 abuts against the outside of the two centering shafts 36 and pushes the centering shafts 36 to move upward. At the same time, the angle between the supporting inclined rods 35, the stabilizing rod 34, and the stabilizing frame 23 changes synchronously. Subsequently, the stabilizing frame 23 moves upward, driving the limiting rod 37 to move upward synchronously along the inside of the limiting groove 38. Finally, the dispersed support 24 achieves precise adaptation with the inner contact surface of the steel pipe rod body 12 through the adjustment of the stabilizing frame 23, ensuring that the two maintain stable contact. This can ensure that the steel pipe rod body 12 and the turning tool head 11 always maintain precise correspondence, thereby ensuring that the turning tool head 11 can complete the turning operation on the steel pipe rod body 12. refer to Figure 2 , Figure 3 and Figure 6 As shown, when the steel pipe rod body 12 is in contact with the stabilizer 23, the outer screw ring 54 is first rotated to form a helical transmission engagement with the inner screw cylinder 53. With the rotation of the outer screw ring 54, the contact groove 55 moves deeper into the inner screw cylinder 53, simultaneously achieving horizontal displacement of the contact groove 55. During this movement, the contact groove 55 gradually comes into contact with the elastic cone pad 52 and continuously pushes the elastic cone pad 52 towards the outside of the steel pipe rod body 12. As the elastic cone pad 52 moves... This will cause the flexible plate 51 to swing slightly through the expansion joint 56, thereby allowing the flexible plate 51 to adapt to the shape of one end of the mounting plate 22, avoiding structural damage caused by rigid tension. Finally, the elastic cone pad 52 deforms itself under the continuous force of the contact groove 55, which can accurately fit the uneven surface of the steel pipe rod body 12, effectively filling the small gaps between the two, ensuring the contact stability between the steel pipe rod body 12 and the stabilizer 23, and providing reliable support for subsequent turning operations. refer to Figure 2and Figure 8 As shown, when turning operations are required at different positions of the steel pipe pole body 12, the servo motor 71 is first started, and its output drives one of the pulleys 73 to rotate synchronously. When the pulley 73 rotates, it drives the other pulley 73 to rotate synchronously along one end of the mounting frame 21 through meshing transmission with the belt 72. As the other pulley 73 rotates, the mounting plate 22 connected to it also rotates along one end of the mounting frame 21, thereby driving the steel pipe pole body 12 to rotate synchronously along the top of the base bracket 25. Through this transmission chain, the turning position of the steel pipe pole body 12 can be flexibly switched to meet the processing needs of different parts. Simultaneously, the servo motor 71 also drives the rotating column 77 to rotate synchronously. When the rotating column 77 rotates along the inside of the base bracket 25, it drives the transmission belt 76 to rotate synchronously. In turn, the transmission belt 76 drives the concentric column 75 to rotate synchronously along the inside of the base bracket 25. After the concentric column 75 rotates, it directly drives the auxiliary roller 74 to rotate synchronously. The auxiliary roller 74 always maintains rolling contact with the outer wall of the steel pipe rod body 12, providing stable radial constraint for the rotating steel pipe rod body 12 and preventing it from radially deviating due to centrifugal force or cutting force. Through the linkage of the dual transmission chains by the single servo motor 71, the turning position of the steel pipe rod body 12 can be flexibly adjusted, and its stability during the rotation process can be ensured simultaneously, providing reliable support for high-precision turning in multiple positions.
