Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel pipe production and processing technology, specifically to a rapid grinding device for steel pipe production. Background Technology
[0002] In modern industrial production, steel pipes are a widely used basic material. Their quality and surface condition have a crucial impact on subsequent processing and performance. Whether used in building structures, machinery manufacturing, petrochemicals, transportation, or other fields, there are strict requirements for the surface quality of steel pipes. In the steel pipe production process, the grinding process is an indispensable key step. Its purpose is to remove oxide scale, weld excess, scratches, and other defects from the surface of the steel pipe, so that the surface of the steel pipe meets the specified roughness and smoothness standards, thereby improving the corrosion resistance, aesthetics, and connection performance with other components of the steel pipe.
[0003] Currently, most steel pipe grinding devices on the market have numerous drawbacks. In terms of grinding efficiency, most traditional devices employ relatively simple grinding methods, such as single-head grinding or simple manual-assisted grinding. They can only process a localized area of the steel pipe at a time, and the grinding speed is limited by the equipment structure and power output, making it difficult to achieve rapid and continuous grinding operations. This severely restricts capacity expansion in large-scale steel pipe production. Regarding grinding quality, manual operation is prone to uneven grinding force due to worker fatigue and varying skill levels, resulting in inconsistent grinding depths on the steel pipe surface. Even some automated grinding equipment suffers from fixed grinding head trajectories and a lack of adaptive adjustment mechanisms. This makes it impossible to precisely conform to the steel pipe surface for uniform grinding of different diameters and ellipticities, failing to meet the stringent surface quality requirements of high-end manufacturing industries.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1:
[0022] Please see Figure 1-4As shown in the figure, this embodiment proposes a rapid grinding device for steel pipe production, including a mounting platform 1. A drawer 2 is movably connected to the front of the mounting platform 1. A material discharge groove 3 is formed inside the upper surface of the mounting platform 1, and the material discharge groove 3 is connected to the drawer 2. Slide grooves 4 are formed on the left and right sides of the mounting platform 1. A pair of mounting plates 5 are fixed to the left and right sides of the upper surface of the mounting platform 1. A first bidirectional drive motor 6 is fixed to the upper surface of one mounting plate 5. A first rotating shaft 7 is rotatably connected to the left and right sides of the first bidirectional drive motor 6. A first moving plate 8 is slidably connected to the outer wall of the first rotating shaft 7, and the first moving plate 8 is connected to the slide groove 4. A limit plate 9 is provided on one side of the first rotating shaft 7, and the limit plate 9 is connected to the mounting plate 5. The material discharge groove 3 inside the upper surface of the mounting platform 1 is connected to the drawer 2 movably connected to the front. The debris generated during the grinding process can fall directly into the drawer 2 through the material discharge groove 3, which is convenient for centralized collection and cleaning of debris, effectively maintaining the cleanliness of the working area, reducing the risk of equipment failure caused by debris accumulation, and reducing equipment costs. To reduce maintenance difficulty and frequency, and improve the working environment by reducing the health hazards of dust to operators, the sliding grooves 4 on the left and right sides of the mounting platform 1 are connected to the first moving plate 8, providing a precise sliding track for the first moving plate 8. The first bidirectional drive motor 6 drives the first rotating shaft 7 to rotate, thereby driving the first moving plate 8, which is slidably connected to the outer wall, to move smoothly along the sliding grooves 4. This allows the device to flexibly and efficiently adjust the grinding position according to different grinding requirements of steel pipes, greatly improving the efficiency and targeting of grinding operations. It is suitable for diverse grinding tasks of steel pipes of different specifications. The limiting plate 9 on one side of the first rotating shaft 7 is connected to the mounting plate 5. The limiting plate 9 can precisely limit the movement range of the first moving plate 8. During the operation of the equipment, it effectively prevents the first moving plate 8 from detaching from the device due to excessive movement, avoiding collisions and interference with other components, thereby ensuring the stable and reliable operation of the entire grinding device, extending the service life of the equipment, reducing downtime caused by equipment failure, and improving production continuity.
[0023] Preferably, a first slide rail 10 is fixedly connected to the upper surface of an mounting plate 5. A second movable plate 11 is slidably connected to the outer wall of the first slide rail 10. A connecting rod 12 is movably connected to one side of the second movable plate 11, and the connecting rod 12 is connected to the first movable plate 8. A clamping ring 13 is movably connected to the outer wall of the connecting rod 12. Through the sliding cooperation between the first slide rail 10 and the second movable plate 11, and the connection of the connecting rod 12, the position of the clamping ring 13 can be flexibly adjusted according to actual needs. When the first movable plate 8 moves under the drive of the first rotating shaft 7, it will drive the second movable plate 11 to slide on the first slide rail 10 through the connecting rod 12, thereby changing the position of the clamping ring 13, which can better adapt to steel pipes of different lengths and positions. The device's adaptability to different specifications of steel pipes is improved by addressing clamping requirements. Furthermore, the clamping ring 13 is movably connected to the outer wall of the connecting rod 12, enabling more stable clamping of the steel pipe. During grinding, this structure reduces the swaying and displacement of the steel pipe, ensuring its positional accuracy and thus improving grinding quality and resulting in a more uniform grinding effect. Secondly, by utilizing the linkage between the first moving plate 8, the second moving plate 11, the connecting rod 12, and the clamping ring 13, the position adjustment of the clamping ring 13 and the clamping operation of the steel pipe can be achieved simply by controlling the first bidirectional drive motor 6. This eliminates the need for complex manual adjustments, simplifying the operation process, reducing the labor intensity of operators, and also reducing clamping errors caused by improper human operation, thereby improving work efficiency and production safety.
[0024] Preferably, a second bidirectional drive motor 14 is fixedly connected to the upper surface of the mounting platform 1. A second rotating shaft 15 is rotatably connected to the left and right sides of the second bidirectional drive motor 14. Second slide rails 16 are fixedly connected to the left and right sides of the upper surface of the mounting platform 1. A first sliding plate 17 is movably connected to the outer wall of the second slide rails 16 and the second rotating shaft 15. A connecting plate 18 is provided on the upper surface of the first sliding plate 17. A mounting base 19 is movably connected to the upper surface of the connecting plate 18. A pair of third slide rails 20 are fixedly connected to the upper surface of the first sliding plate 17, and the third slide rails 20 are slidably connected to the connecting plate 18. The second bidirectional drive motor 14 drives the second rotating shaft 15 to rotate, causing the first sliding plate 17 to move left and right on the second slide rails 16. This design can precisely control the position of the grinding components in the horizontal direction. The grinding position can be flexibly and precisely adjusted according to the grinding requirements of different parts of the steel pipe, achieving comprehensive and meticulous grinding of the steel pipe surface. This greatly improves the accuracy and quality of the grinding operation, ensuring that every area of the steel pipe achieves the ideal grinding effect. The third slide rail 20 is slidably connected to the connecting plate 18, and the upper surface of the connecting plate 18 is movably connected to the mounting seat 19, allowing the mounting seat 19 to be finely adjusted in the horizontal direction. Combined with the overall left and right movement of the first sliding plate 17, it can better adapt to steel pipes of different diameters, lengths, and shapes. For steel pipes with large diameter variations, the position of the mounting seat 19 on the connecting plate 18 and the position of the first sliding plate 17 on the second slide rail 16 can be adjusted to ensure that the grinding device can always accurately grind the surface of the steel pipe, significantly enhancing the versatility and practicality of the device. The second slide rail 16 provides stable sliding support for the first sliding plate 17, and the third slide rail 20 ensures the smooth movement of the connecting plate 18. During the grinding process, even if the grinding components operate at high speed, the entire structure can effectively reduce vibration and displacement, ensuring that the grinding operation is carried out continuously and stably. Stable operation not only helps to improve grinding quality but also extends the service life of various components of the equipment, reduces equipment failure rate, reduces downtime caused by equipment maintenance, and improves production efficiency.
[0025] Preferably, a support plate 21 is fixedly connected inside the mounting base 19. A servo motor 22 is fixedly connected to the upper surface of the support plate 21. A pair of first rotating shafts 23 are rotatably connected inside the support plate 21, and the first rotating shafts 23 are interconnected with the servo motor 22. A lifting plate 24 is slidably connected to the outer wall of the first rotating shafts 23. A synchronous motor 25 is fixedly connected to the upper surface of the lifting plate 24. A second rotating shaft 26 is rotatably connected to the lower surface of the synchronous motor 25. A first meshing gear 27 is rotatably connected to the outer wall of the second rotating shaft 26. A first connecting shaft 28 is rotatably connected to the lower surface of the lifting plate 24. A second meshing gear 29 is rotatably connected to the outer wall of the first connecting shaft 28, and the second meshing gear 29 meshes with the first meshing gear 27 for transmission. The servo motor 22 drives the first rotating shaft 23 to rotate. Because the lifting plate 24 and the first rotating shaft 26 are connected to the first rotating shaft 23, the servo motor 22 drives the first rotating shaft 23 to rotate. The outer wall of shaft 23 is slidably connected. The rotation of the first rotating shaft 23 allows the lifting plate 24 to move up and down along the first rotating shaft 23. This function allows for precise adjustment of the height position of the grinding components according to different specifications such as the diameter and wall thickness of the steel pipe and the actual grinding requirements, so that the grinding device can better fit the surface of the steel pipe, ensuring the consistency and high quality of the grinding effect, and enhancing the adaptability of the device to different types of steel pipes. Secondly, the synchronous motor 25 drives the second rotating shaft 26 to rotate. Through the meshing transmission of the first meshing gear 27 and the second meshing gear 29, the power is transmitted to the first connecting shaft 28. The gear meshing transmission has the advantages of high transmission efficiency, accurate transmission ratio, and reliable operation, which can ensure stable and precise power transmission, enabling the grinding components to work at a stable speed and torque, effectively improving the grinding quality and efficiency.
[0026] Preferably, a first synchronous gear 30 is rotatably connected to the outer wall of the first connecting shaft 28, a grinding disc 31 is rotatably connected to the lower surface of the first connecting shaft 28, a second synchronous gear 32 is rotatably connected to one side of the first synchronous gear 30, a second connecting shaft 33 is rotatably connected to the lower surface of the second synchronous gear 32, and the second connecting shaft 33 passes through the interior of the grinding disc 31. An elastic support seat 34 is movably connected to the lower surface of the second connecting shaft 33, and a grinding wheel 35 is movably connected to the lower surface of the elastic support seat 34. The output end of the second connecting shaft 33 is connected to the grinding wheel 35. The first connecting shaft 28 drives the first synchronous gear 30 to rotate, and the first synchronous gear 30 and the second synchronous gear 32 cooperate with each other, causing the second connecting shaft 33 to rotate accordingly. This synchronous transmission structure can realize the simultaneous operation of multiple grinding wheels 35, greatly improving grinding efficiency. Multiple grinding wheels 35 simultaneously grind the surface of the steel pipe, completing the grinding task in a shorter time, adapting to the needs of large-scale production. Moreover, the multiple grinding wheels 35 play a role in synchronous transmission. Under these conditions, the grinding wheel 35 can maintain a relatively stable rotation speed and motion state, uniformly grinding the surface of the steel pipe. This avoids the uneven grinding problem that may occur due to grinding by a single grinding wheel 35, improving the grinding quality of the steel pipe surface and making the surface roughness and smoothness more consistent. Secondly, the elastic support seat 34 provides a certain buffer and self-adaptive capability for the grinding wheel 35. When the surface of the steel pipe is uneven or irregular in shape, the elastic support seat 34 can elastically deform according to the actual situation, allowing the grinding wheel 35 to better fit the surface of the steel pipe and ensure the grinding effect. At the same time, the elastic support seat 34 can also reduce the vibration and impact generated during the grinding process, reduce the risk of damage to the equipment, and extend the service life of the equipment. The grinding wheel 35 is movably connected to the second connecting shaft 33 through the elastic support seat 34, which allows the grinding wheel 35 to be easily and quickly replaced when worn or damaged. Operators can complete the replacement of the grinding wheel 35 without complicated tools and operating procedures, reducing equipment downtime and improving production efficiency.
[0027] Preferably, an air pump 36 is fixedly connected to one side of the first sliding plate 17, and an air rod 37 is movably connected to one side of the air pump 36. An adjusting bolt 38 is movably connected inside the mounting base 19. The air pump 36 is connected to the connecting plate 18 through the air rod 37, which can precisely control the forward and backward movement of the connecting plate 18 on the third slide rail 20. When grinding steel pipes of different specifications, there may be slight differences in the position of the area to be ground on the steel pipe. For some steel pipes with special weld positions or local defects that require precise grinding, the air pump 36 can precisely adjust the extension and retraction length of the air rod 37 according to the preset program or the real-time instructions of the operator, so as to drive the grinding components on the connecting plate 18 and the mounting base 19 to achieve millimeter-level or even smaller displacement adjustments in the horizontal direction.
[0028] When using this invention, the power is turned on, and all power components such as motors and air pumps 36 enter standby mode. The operator places the steel pipe to be ground in the designated position and controls the first bidirectional drive motor 6 to rotate, driving the first rotating shaft 7 to rotate. The rotation of the first rotating shaft 7 causes the first moving plate 8, which is slidably connected to it, to move within the sliding grooves 4 opened on the left and right sides of the mounting platform 1. The first moving plate 8 drives the second moving plate 11 to slide on the first slide rail 10 through the connecting rod 12, thereby moving the clamping ring 13, which is movably connected to the outer wall of the connecting rod 12, to a suitable position to firmly clamp the steel pipe, completing the clamping and positioning work of the steel pipe. To adapt to the grinding needs of steel pipes of different lengths and diameters, the position of the grinding components needs to be roughly adjusted. The second bidirectional drive motor 14 is started, and its output power drives the second rotating shaft 15 to rotate. Since the second rotating shaft 15 is movably connected to the first sliding plate 17 on the second slide rail 16, the first sliding plate 17 will move smoothly left and right on the second slide rail 16 as the second rotating shaft 15 rotates. The movement of the first sliding plate 17 drives the connecting plate 18 and the mounting base 19 and other grinding-related components above it to move horizontally synchronously, initially adjusting the grinding position so that the grinding components are close to the area of the steel pipe to be ground. The servo motor 22 starts to work on the bracket plate 21 fixed inside the mounting base 19. The servo motor 22 drives the pair of first rotating shafts 23 connected to it to rotate inside the bracket plate 21. Because the lifting plate 24 is connected to the outer wall of the first rotating shaft 23, the servo motor 22 drives the pair of first rotating shafts 23 connected to it to rotate inside the bracket plate 21. The sliding connection allows the lifting plate 24 to move up and down along the first rotating shaft 23 when the first rotating shaft 23 rotates. This vertical displacement adjustment can precisely control the height of the grinding disc 31 and grinding wheel 35 installed below the lifting plate 24, maintaining a suitable grinding distance from the steel pipe surface to meet the grinding requirements of steel pipes with different diameters and wall thicknesses. The air pump 36, fixed to one side of the first sliding plate 17, starts. The air pump 36 is connected to the connecting plate 18 via an air rod 37. When the air pump 36 is working, it outputs gas at different pressures according to a preset program or operator instructions, pushing the air rod 37 to extend and retract. The extension and retraction of the air rod 37 causes the connecting plate 18 to move back and forth on a pair of third slide rails 20 fixed to the upper surface of the first sliding plate 17. The movement of 18 then drives the mounting base 19 and the entire grinding assembly to make fine horizontal displacement adjustments, ensuring that the grinding components can be accurately aligned with the specific grinding area on the steel pipe surface, further improving the accuracy of the grinding operation. The adjusting bolt 38, which is movably connected inside the mounting base 19, allows the operator to manually rotate to make minor horizontal or vertical displacement adjustments to the mounting base 19 in special working conditions requiring extremely high grinding position accuracy, achieving extremely precise positioning of the grinding position. Once the grinding position is adjusted, the synchronous motor 25 fixed to the upper surface of the lifting plate 24 starts, driving the second rotating shaft 26 to rotate. The first meshing gear 27, rotatably connected to the outer wall of the second rotating shaft 26, rotates accordingly.The first meshing gear 27 meshes with the second meshing gear 29 on the outer wall of the first connecting shaft 28, which is rotatably connected to the lower surface of the lifting plate 24, transmitting power to the first connecting shaft 28. When the first connecting shaft 28 rotates, it drives the first synchronous gear 30, which is rotatably connected to its outer wall, to rotate. The first synchronous gear 30 cooperates with the second synchronous gear 32, which is rotatably connected to one side, causing the second connecting shaft 33, which is rotatably connected below the second synchronous gear 32, to rotate. The second connecting shaft 33 passes through the interior of the grinding disc 31, and its output end is connected to the grinding wheel 35, ultimately driving the grinding disc 31 and the grinding wheel. The high-speed rotation of the air pump 35 performs grinding operations on the surface of the steel pipe. The coordinated transmission of multiple gears ensures the stability and reliability of power transmission, achieving synchronous rotation of multiple grinding wheels 35, which greatly improves grinding efficiency and uniformity. During the grinding process, in addition to assisting the movement of the connecting plate 18, the air pump 36 also plays an important role in adjusting the grinding pressure. According to the material hardness of the steel pipe and the grinding process requirements, the extension and retraction state of the air rod 37 can be changed by adjusting the output pressure of the air pump 36. For example, when grinding steel pipes with higher hardness, increasing the output pressure of the air pump 36 will adjust the extension and retraction state of the air rod 37. The extension pushes the mounting base 19 and grinding components closer to the steel pipe, increasing the grinding pressure of the grinding wheel 35 on the steel pipe surface and improving grinding efficiency. When grinding thin-walled or easily deformable steel pipes, the output pressure of the air pump 36 is reduced, and the air rod 37 retracts, lowering the grinding pressure of the grinding wheel 35 on the steel pipe to prevent damage due to excessive pressure. Furthermore, the elastic support 34, movably connected to the lower surface of the second connecting shaft 33, can elastically deform according to the unevenness of the steel pipe surface when the grinding wheel 35 contacts the steel pipe surface. This allows the grinding wheel 35 to better conform to the steel pipe surface, ensuring efficient grinding. On the one hand, it reduces vibration and impact during grinding, protecting equipment components and extending equipment lifespan. During the grinding process, the debris generated by the friction between the grinding wheel 35 and the steel pipe surface falls under gravity through the discharge groove 3 inside the upper surface of the mounting platform 1 into the drawer 2 movably connected to the front of the mounting platform 1. This design facilitates centralized collection and cleaning of debris, keeping the work area clean, reducing the risk of equipment failure due to debris accumulation, lowering the difficulty and frequency of equipment maintenance, and improving the working environment while reducing the health hazards of dust to operators.
