Description

Technical Field

[0001] This invention relates to the field of steel structure construction technology, and in particular to a positioning and forming device and method for ultra-large diameter annular steel components. Background Technology

[0002] The ultra-large diameter ring steel component positioning and forming device is a specialized piece of equipment used for the precise positioning and shaping of ultra-large diameter ring steel components. In fields such as bridge construction, large machinery manufacturing, and aerospace, ultra-large diameter ring steel components are crucial, and their processing accuracy directly affects the stability and safety of the overall structure. This device provides a reliable foundation for subsequent processing steps such as welding, cutting, and grinding by precisely positioning and firmly clamping the ring steel component, ensuring that the ring steel component can be formed according to design requirements and guaranteeing the quality of the project or product.

[0003] However, existing positioning and forming devices for ultra-large diameter ring steel components have many shortcomings in practical applications. First, the positioning accuracy is insufficient and adjustment is inconvenient. Most existing devices rely on manual adjustment or simple mechanical structures for positioning, making it difficult to achieve rapid and accurate position calibration for ring steel components of different diameters. This easily leads to positioning deviations, affecting the accuracy of subsequent processing. Especially for ultra-large diameter ring steel components, manual adjustment is not only inefficient but also fails to ensure uniform force in all directions, causing the component to shift during processing. Second, the clamping stability is poor and the adaptability is limited. The clamping structure of existing devices is usually designed with fixed dimensions or a small adjustment range, which cannot flexibly adapt to ultra-large diameter ring steel components of different thicknesses and diameters. During clamping, loosening or excessive compression is prone to occur, which can affect processing quality or even cause component deformation and damage. At the same time, existing devices lack an effective cleaning mechanism. During long-term use, processing debris accumulates in sliding parts such as the chute, affecting the operating accuracy and service life of the device, and increasing maintenance costs and workload.

[0004] Therefore, it is necessary to provide a new positioning and forming device and method for ultra-large diameter annular steel components to solve the above-mentioned technical problems. Summary of the Invention

[0007] Preferably, the unfolding component includes: a turntable, a third slide groove, and a slide column; the turntable is rotatably connected to the inside of the base, and the upper surface of the turntable is provided with a third slide groove at equal intervals along the circumferential direction. The third slide groove is arc-shaped, and the bottom of the slide plate is fixedly connected to a slide column, which slides within the third slide groove.

[0008] Preferably, the clamping assembly includes: a threaded rod and a threaded slider; the threaded rod is rotatably connected inside the slide plate, and the threaded slider is fixedly connected to the bottom of the outer clamping plate. The outer clamping plate slides in the second slide groove through the threaded slider, and the threaded slider is threadedly connected to the threaded rod.

[0009] Preferably, the drive assembly includes: a gear disk, gears, external splines, spline rods, and internal splines; the gear disk is rotatably connected inside the base, and multiple sets of gears are equidistantly rotatably connected inside the base above the gear disk, the gear disk meshes with the gears, an external spline is provided in the middle of the gears, a spline rod is equidistantly slidably connected inside the base above the gear disk, an internal spline is provided on the side wall of the spline rod, the internal spline is slidably connected with the external spline, and one end of the spline rod extends out of the slide plate and is fixedly connected to the threaded rod.

[0010] Preferably, the cleaning components include: mounting plates, brush rollers, friction wheels, fourth slide grooves, and friction plates; mounting plates are symmetrically and fixedly connected to one end of the slide plate away from the inner clamping plate, brush rollers are rotatably connected between the mounting plates, the two ends of the brush rollers extend out of the mounting plates and are fixedly connected to friction wheels, fourth slide grooves are provided on both sides of the first slide groove, the friction wheels slide in the fourth slide grooves, and friction plates are fixedly connected to the top of the inner wall of the fourth slide grooves, with friction plates rubbing against the friction wheels.

[0011] Preferably, an electric push rod is installed inside the base, and the output end of the electric push rod is rotatably connected to the eccentric part of the bottom of the turntable.

[0012] Preferably, a motor is fixedly connected inside the base, a worm is fixedly connected to the output end of the motor, a worm wheel is installed on the top of the gear plate, and the worm wheel meshes with the worm.

[0013] Preferably, a baffle is fixedly connected to one end of the slide plate near the inner clamping plate. The baffle is slidably connected to the base and is used to cover the first slide groove.

[0014] Preferably, a rotating roller is rotatably connected to the side of the outer clamping plate closest to the inner clamping plate.

[0015] A method for using a positioning and forming device for ultra-large diameter annular steel components includes the following steps:

[0016] S1. The ring-shaped steel component body is placed on the base, and the ring-shaped steel component body is located between the inner clamping plate and the outer clamping plate.

[0017] S2. Start the electric push rod. The output end of the electric push rod extends and drives the turntable to rotate. The turntable then drives the slide plate to move away from the base axis through the third slide groove and the slide column until the distance between the end of the inner clamping plate away from the base axis and the base axis is equal to the radius of the annular steel component body. During the process of the slide plate moving away from the base axis, the friction wheel rubs against the friction plate, thereby driving the brush roller to rotate. The brush roller sweeps the debris from the previous processing located at the bottom of the first slide groove outward.

[0018] S3. Start the motor. The motor drives the worm gear to rotate, which in turn drives the gear plate to rotate through the worm wheel. The gear plate drives the threaded rod to rotate through the gear and spline rod, which in turn drives the outer clamping plate to move closer to the inner clamping plate through the slider, thereby clamping the ring steel component body.

[0019] Compared with related technologies, the positioning and forming device and method for ultra-large diameter annular steel components provided by the present invention have the following beneficial effects:

[0020] High positioning accuracy and easy adjustment:

[0021] This invention achieves precise and efficient adjustment of the slide plate position through an unfolding assembly. The turntable in the unfolding assembly rotates under the drive of an electric push rod, and the cooperation of the arc-shaped third slide groove and the slide column drives multiple slide plates to slide synchronously along the first slide groove, thereby precisely adjusting the distance between the slide plate and the base axis. This design overcomes the limitations of manual adjustment or simple mechanical structure adjustment in existing devices, eliminates the need for manual operation one by one, and can quickly adapt to ring steel components of different diameters, ensuring that the inner clamping plate accurately reaches the required position, effectively avoiding positioning deviation, greatly improving positioning accuracy and adjustment efficiency, and solving the problems of insufficient positioning accuracy and inconvenient adjustment in existing devices.

[0022] It has strong clamping stability and good adaptability:

[0023] The clamping assembly and driving assembly of this invention work together to exhibit excellent performance. In the driving assembly, the motor drives the geared disc to rotate via a worm gear and worm wheel. The geared disc drives multiple sets of gears to rotate. Then, through the sliding connection of the external and internal splines, the spline rod drives the threaded rod to rotate. Finally, the outer clamping plate slides along the second sliding groove under the action of the threaded slider, thereby clamping the annular steel component. This linkage design ensures that multiple outer clamping plates move synchronously, making the annular steel component evenly stressed and enhancing the stability of clamping. At the same time, the sliding distance of the outer clamping plate can be precisely controlled by the threaded rod, which can flexibly adapt to annular steel components of different thicknesses. This avoids problems such as loosening and excessive compression caused by the fixed clamping structure or small adjustment range of existing devices, and also solves the defects of limited adaptability. In addition, the rotating rollers on the outer clamping plate can reduce friction with the component during clamping and protect the surface of the component from damage.

[0024] Ensure the long-term stable operation of the equipment:

[0025] As the slide plate moves within the first groove, the friction wheels at both ends of the brush roller slide within the fourth groove, generating friction with the friction plate and causing the brush roller to rotate, thus promptly sweeping away debris from the bottom of the first groove. This design compensates for the lack of an effective cleaning mechanism in existing devices, preventing debris accumulation from affecting the sliding accuracy of the slide plate and the lifespan of the device, reducing the workload and maintenance costs of manual cleaning, and ensuring long-term stable operation of the device. Furthermore, the baffle on the slide plate can block the first groove, preventing debris from entering the base, further improving the cleanliness and reliability of the device.

[0026] High degree of automation:

[0027] This invention achieves orderly and coordinated operation of the unfolding and clamping components through a driving component. The overall structure is compact, and the components work together seamlessly, improving work efficiency while reducing operational complexity. Whether it is positioning adjustment, clamping and fixing, or cleaning, there is no need for much manual intervention. The degree of automation is high, which can significantly improve the overall work quality and efficiency of positioning and forming ultra-large diameter ring steel components, and better meet the high precision requirements of ring steel component processing in fields such as bridge construction and large machinery manufacturing.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the invention and are not intended to limit the invention.

[0039] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0040] Please see Figures 1 to 9A positioning and forming device for an ultra-large diameter annular steel component, comprising: a base 1, on the top of which an annular steel component body 2 is placed; characterized in that: a first sliding groove 3 is equidistantly provided on the top of the base 1, a sliding plate 4 is slidably connected in each of the first sliding grooves 3, an inner clamping plate 5 is fixedly connected to the top of one end of the sliding plate 4, a second sliding groove 6 is provided at the end of the sliding plate 4 away from the inner clamping plate 5, an outer clamping plate 7 is slidably connected inside the second sliding groove 6, and the inner clamping plate 5 and the outer clamping plate 7 together clamp the annular steel component body 2; an unfolding assembly is installed inside the base 1, which is used to adjust the distance between the sliding plate 4 and the axis of the base 1; a clamping assembly is installed inside the sliding plate 4, which is used to drive the outer clamping plate 7 to slide along the long axis of the second sliding groove 6; a driving assembly is installed inside the base 1, which is used to drive the unfolding assembly and the clamping assembly to run; a cleaning assembly is installed at one end of the sliding plate 4, which is used to clean the first sliding groove 3; a rotating roller 28 is rotatably connected to the side of the outer clamping plate 7 near the inner clamping plate 5.

[0041] It should be noted that the rotating roller 28 connected to the side of the outer clamping plate 7 closest to the inner clamping plate 5 can reduce the friction between the outer clamping plate 7 and the annular steel component body 2 during the clamping process, thus avoiding damage to the surface of the component.

[0042] Please see Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 9 The unfolding components include: a turntable 8, a third slide groove 9, and a slide column 10; the turntable 8 is rotatably connected inside the base 1, and the third slide groove 9 is equidistantly opened on the upper surface of the turntable 8 along the circumferential direction. The third slide groove 9 is arc-shaped, and the slide column 10 is fixedly connected to the bottom of the slide plate 4. The slide column 10 slides in the third slide groove 9; an electric push rod 23 is installed inside the base 1, and the output end of the electric push rod 23 is rotatably connected to the eccentric part of the bottom of the turntable 8.

[0043] It should be noted that the output end of the electric push rod 23 is rotatably connected to the eccentric part at the bottom of the turntable 8 so as to efficiently drive the turntable 8 to rotate through the extension and retraction of the electric push rod 23. When the output end of the electric push rod 23 extends or retracts, since the connection point is located at the eccentric part at the bottom of the turntable 8, a torque will be generated to drive the turntable 8 to rotate around its own axis, thereby causing the third slide groove 9 on the turntable 8 to rotate synchronously.

[0044] Please see Figure 6 , Figure 7 and Figure 9The clamping assembly includes: a threaded rod 11 and a threaded slider 12; the threaded rod 11 is rotatably connected inside the slide plate 4, and the threaded slider 12 is fixedly connected to the bottom of the outer clamping plate 7. The outer clamping plate 7 slides in the second slide groove 6 via the threaded slider 12, and the threaded slider 12 is threadedly connected to the threaded rod 11; the driving assembly includes: a gear disc 13, gears 14, an external spline 15, a spline rod 16, and an internal spline 17; the gear disc 13 is rotatably connected inside the base 1, and multiple sets of gears 14 are equidistantly rotatably connected inside the base 1 above the gear disc 13. Gear 13 meshes with gear 14. Gear 14 has an external spline 15 in the middle. Spline rod 16 is equidistantly slidably connected inside the base 1 above gear 13. Spline rod 16 has an internal spline 17 on its side wall. The internal spline 17 is slidably connected to the external spline 15. One end of spline rod 16 extends out of the slide plate 4 and is fixedly connected to threaded rod 11. Motor 24 is fixedly connected inside the base 1. Worm 25 is fixedly connected to the output end of motor 24. Worm wheel 26 is installed on the top of gear 13. Worm wheel 26 meshes with worm 25.

[0045] It should be noted that the length of the spline rod 16 is greater than the length of the first slide groove 3. The spline rod 16 can ensure that after the slide plate 4 slides, the gear plate 13 can still drive the threaded rod 11 to rotate through the gear 14 and the spline rod 16.

[0046] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The cleaning components include: mounting plate 18, brush roller 19, friction wheel 20, fourth slide groove 21, and friction plate 22; the end of the slide plate 4 away from the inner clamping plate 5 is symmetrically and fixedly connected to the mounting plate 18, and the brush roller 19 is rotatably connected between the mounting plates 18. The two ends of the brush roller 19 extend out of the mounting plate 18 and are fixedly connected to the friction wheel 20. The first slide groove 3 has a fourth slide groove 21 on both sides, and the friction wheel 20 slides in the fourth slide groove 21. The friction plate 22 is fixedly connected to the top of the inner wall of the fourth slide groove 21, and the friction plate 22 is in frictional contact with the friction wheel 20; the end of the slide plate 4 near the inner clamping plate 5 is fixedly connected to the baffle 27, which is slidably connected to the base 1 and is used to cover the first slide groove 3.

[0047] It should be noted that the friction plate 22 is positioned above the friction wheel 20. When the slide plate 4 slides outward along the first slide groove 3, the friction between the friction wheel 20 and the friction plate 22 will cause the friction wheel 20 to rotate, making the movement direction of the bottom of the brush roller 19 consistent with that of the slide plate 4, thus sweeping out the debris at the bottom of the first slide groove 3.

[0048] A method for using a positioning and forming device for ultra-large diameter annular steel components includes the following steps:

[0049] S1. The annular steel component body 2 is placed on the base 1, and the annular steel component body 2 is located between the inner clamping plate 5 and the outer clamping plate 7.

[0050] S2. Start the electric push rod 23. The output end of the electric push rod 23 extends and drives the turntable 8 to rotate. The turntable 8 then drives the slide plate 4 to move away from the axis of the base 1 through the third slide groove 9 and the slide column 10 until the distance between the end of the inner clamping plate 5 away from the axis of the base 1 and the axis of the base 1 is equal to the radius of the annular steel component body 2. During the process of the slide plate 4 moving away from the axis of the base 1, the friction wheel 20 rubs against the friction plate 22, thereby driving the brush roller 19 to rotate. The brush roller 19 sweeps the debris from the previous processing located at the bottom of the first slide groove 3 outward.

[0051] S3. Start the motor 24. The motor 24 drives the worm gear 25 to rotate, which in turn drives the gear plate 13 to rotate through the worm wheel 26. The gear plate 13 drives the threaded rod 11 to rotate through the gear 14 and the spline rod 16, which in turn drives the outer clamping plate 7 to approach the inner clamping plate 5 through the slider, thereby clamping the annular steel component body 2.

[0052] The working principle of the ultra-large diameter annular steel component positioning and forming device provided by this invention is as follows:

[0053] Placement of the ring-shaped steel component body 2:

[0054] When positioning and forming the ring-shaped steel component body 2, the ring-shaped steel component body 2 is first placed on the base 1, and it is ensured that it is between the inner clamping plate 5 and the outer clamping plate 7, in preparation for subsequent positioning and clamping operations.

[0055] Adjust the position of skateboard 4:

[0056] When it is necessary to adjust the distance between the slide plate 4 and the axis of the base 1 to adapt to the size of the annular steel component body 2, the unfolding assembly begins to function; the electric push rod 23 installed inside the base 1 is activated, and the output end of the electric push rod 23 extends out. Since its output end is rotatably connected to the eccentric part at the bottom of the turntable 8, it will drive the turntable 8 to rotate inside the base 1; the arc-shaped third sliding groove 9 equidistantly opened along the circumferential direction on the upper surface of the turntable 8 will rotate accordingly, and the sliding column 10 fixedly connected to the bottom of the slide plate 4 will slide in the third sliding groove 9. Under the action of the rotation of the turntable 8, the sliding column 10 will drive the slide plate 4 to slide along the first sliding groove 3, thereby realizing the adjustment of the distance between the slide plate 4 and the axis of the base 1 until the distance between the end of the inner clamping plate 5 away from the axis of the base 1 and the axis of the base 1 is equal to the radius of the annular steel component body 2, completing the initial position adjustment.

[0057] Cleaning process:

[0058] During the movement of the slide plate 4, the cleaning components work synchronously. The brush roller 19, which is symmetrically and fixedly connected to the mounting plate 18 at the end of the slide plate 4 away from the inner clamping plate 5, slides in the fourth slide groove 21 opened on both sides of the first slide groove 3. Since the friction plate 22 fixedly connected to the top of the inner wall of the fourth slide groove 21 is in frictional connection with the friction wheel 20, when the slide plate 4 moves, the friction wheel 20 and the friction plate 22 rub against each other, driving the brush roller 19 to rotate. The brush roller 19 sweeps the debris generated in the previous processing at the bottom of the first slide groove 3 outward, ensuring the cleanliness of the device's operating environment and preventing debris from affecting the sliding accuracy of the slide plate 4. At the same time, the baffle 27 fixedly connected to the end of the slide plate 4 near the inner clamping plate 5 will block the first slide groove 3 to prevent debris from entering the interior of the base 1.

[0059] Clamping process:

[0060] After the position adjustment is completed, the annular steel component body 2 needs to be clamped and fixed. At this time, the clamping assembly and the drive assembly work together. The motor 24 fixedly connected inside the base 1 is started. The output end of the motor 24 drives the worm 25 to rotate. The worm 25 meshes with the worm wheel 26 installed on the top of the gear disk 13, thereby driving the gear disk 13 to rotate inside the base 1. The gear disk 13 meshes with multiple sets of gears 14 that are equidistantly rotatably connected above it inside the base 1. The rotation of the gear disk 13 drives the gears 14 to rotate. The external spline 15 opened in the middle of the gear 14 is slidably connected to the internal spline 17 opened in the side wall of the spline rod 16 that is equidistantly slidably connected above the gear disk 13 inside the base 1. Therefore, the rotation of the gear 14 will drive the spline rod 16 to rotate. Rotation; one end of the spline rod 16 extends into the slide plate 4 and is fixedly connected to the threaded rod 11 rotatably connected to the inside of the slide plate 4, thereby driving the threaded rod 11 to rotate; the threaded slider 12 fixedly connected to the bottom of the outer clamping plate 7 is threadedly connected to the threaded rod 11, and the outer clamping plate 7 slides in the second slide groove 6 through the threaded slider 12. The rotation of the threaded rod 11 will cause the threaded slider 12 to drive the outer clamping plate 7 to move closer to the inner clamping plate 5 along the long axis of the second slide groove 6. Finally, the inner clamping plate 5 and the outer clamping plate 7 together clamp the annular steel component body 2; in addition, the rotating roller 28 rotatably connected to the side of the outer clamping plate 7 close to the inner clamping plate 5 can reduce the friction between the outer clamping plate 7 and the annular steel component body 2 during the clamping process and avoid damage to the surface of the component.

[0061] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.

The operation method includes the following steps: S1. The ring steel component body (2) is placed on the base (1) and the ring steel component body (2) is located between the inner clamping plate (5) and the outer clamping plate (7); S2. Start the electric push rod (23). The output end of the electric push rod (23) extends and drives the turntable (8) to rotate. The turntable (8) then drives the slide plate (4) to move away from the axis of the base (1) through the third slide groove (9) and the slide column (10) until the distance between the end of the inner clamping plate (5) away from the axis of the base (1) and the axis of the base (1) is equal to the radius of the annular steel component body (2). During the process of the slide plate (4) moving away from the axis of the base (1), the friction wheel (20) rubs against the friction plate (22), which in turn drives the brush roller (19) to rotate. The brush roller (19) sweeps the debris from the previous processing located at the bottom of the first slide groove (3) outward. S3. Start the motor (24). The motor (24) drives the worm (25) to rotate, which in turn drives the gear (13) to rotate through the worm wheel (26). The gear (13) drives the threaded rod (11) to rotate through the gear (14) and spline rod (16), which in turn drives the outer clamping plate (7) to approach the inner clamping plate (5) through the slider, thereby clamping the annular steel component body (2).
