Abstract
Description
Technical Field
[0001] This invention relates to the field of polishing equipment technology, and in particular to a stable internal positioning polishing device with an outer plastic liner and an inner stainless steel tube for backup. Background Technology
[0002] This stable internal positioning polishing device for stainless steel pipes with plastic outer lining is specifically designed to improve the polishing quality and stability of the inner wall of stainless steel pipes. Through a precision positioning system, the device ensures accurate contact between the polishing tool and the inner wall of the pipe, effectively eliminating surface unevenness caused by positioning deviations in traditional polishing. It employs adaptive pressure adjustment technology, dynamically adjusting the polishing pressure according to the pipe thickness and material characteristics to avoid over-grinding or under-polishing. Simultaneously, the integrated stabilizing structure effectively suppresses vibration during the polishing process, improving surface finish. This device is suitable for stainless steel pipes with plastic outer lining of various specifications, significantly improving production efficiency and product qualification rate, and meeting high-precision processing requirements.
[0003] In actual use, the metal particles, plastic debris, and dust generated by traditional polishing devices tend to accumulate on the inner wall of the steel pipe or inside the equipment. These residues can scratch the outer plastic layer or the inner stainless steel lining of the steel pipe, affecting the smoothness and quality of the product. Therefore, a stable internal positioning polishing device with an outer plastic layer and an inner stainless steel lining is proposed for standby. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies, where metal particles, plastic debris, and dust generated during polishing by conventional devices tend to accumulate on the inner wall of steel pipes or inside equipment. These residues can scratch the outer plastic layer or the inner stainless steel lining of the steel pipe, affecting the smoothness and quality of the product. Therefore, this invention proposes a stable internal positioning polishing device for use with outer plastic and inner stainless steel lining pipes.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A stable internal positioning polishing device for spare plastic-lined stainless steel tubing includes a polishing table. A fixing mechanism is provided on the upper part of the polishing table to clamp and fix the steel tubing. A polishing housing is provided on the upper part of the polishing table. A first motor is installed inside the polishing housing. A first gear is provided at the output end of the first motor. The first gear meshes with a second gear, and the second gear meshes with a third gear. An outer rod is fixedly connected to the third gear. A collecting chamber is fixedly connected to the outer rod. An air suction cylinder is fixedly connected inside the collecting chamber. A polishing head is provided at the front end of the collecting chamber. An inner rod is fixedly connected to the first gear. The inner rod and the outer rod are rotatably connected. A turbine is fixedly connected to the inner rod, and the turbine is rotatably connected to the collecting chamber.
[0006] The first motor is started, which drives the first gear to rotate. The rotation of the first gear drives the outer rod to rotate, which in turn drives the collection chamber to rotate, thereby driving the polishing head to rotate. This allows for polishing inside the steel pipe. At the same time, the rotation of the first gear drives the inner rod to rotate, which in turn drives the turbine to rotate. This accelerates the entry of outside air into the collection chamber, creating a negative pressure inside the collection chamber to adsorb the waste residue generated during the polishing process. The surface of the air suction cylinder has micropores to effectively prevent waste residue from entering and obstructing the turbine rotation. The first, second, and third gears have the same module, and the rotation direction of the third gear is opposite to that of the first gear.
[0007] The above technical solution further includes: An air inlet is provided at the rear end of the collection chamber near the turbine.
[0008] An adjustment mechanism is provided at the front end of the collection chamber, and the adjustment mechanism includes a second air chamber located at the upper part of the collection chamber.
[0009] The second air chamber output end is provided with a slide plate, and an adjustment rod is rotatably connected to the upper part of the slide plate. The adjustment rod is rotatably connected to the polishing head, and a connecting rod is rotatably connected to the upper part of the polishing head.
[0010] A spring is fitted around the outside of the adjusting rod to provide damping for the polishing head.
[0011] A first cylinder is provided on the upper part of the polishing table, and a lifting platform is provided at the output end of the first cylinder. The lifting platform and the polishing table are slidably connected. A polishing housing is provided on the upper part of the lifting platform, and a limit structure is provided on the upper part of the lifting platform to ensure stability during the lifting process.
[0012] The fixing mechanism includes a fixing frame fixedly connected to the upper part of the polishing table, a fixing clamp fixedly connected to the bottom of the fixing frame, a fixing housing fixedly connected to the top of the fixing frame, a second motor provided on one side of the fixing housing, and a fixing component provided at the output end of the second motor.
[0013] The fixing assembly includes a worm gear located at the output end of the second motor. The worm gear is meshed with a worm wheel, which is fixedly connected to a fourth gear. The fourth gear is meshed with a transmission rack, and a movable clamping plate is fixedly connected to the bottom of the transmission rack. The movable clamping plate is slidably connected to a slide groove, and the slide groove is fixedly connected to a fixing frame. A slider is provided on the upper part of the movable clamping plate, which is slidably connected to the slide groove. Anti-slip pads are provided on the surfaces of both the fixed clamping plate and the movable clamping plate. The fixed clamping plate and the movable clamping plate have a wedge-shaped structure, which increases the contact area with the surface of the steel pipe.
[0014] The fixed housing is fixedly connected to a limiting groove, and a transmission rack is slidably connected inside the limiting groove.
[0015] The present invention has the following beneficial effects: 1. In this invention, during the polishing process, starting the first motor drives the first gear to rotate. The rotation of the first gear drives the outer rod to rotate, which in turn drives the fixedly connected collection chamber to rotate, thereby driving the polishing head set at the front end to rotate, thus performing polishing treatment inside the steel pipe. During the polishing process, waste residue will continuously fall off. The rotation of the first gear can synchronously drive the inner rod to rotate, which in turn drives the turbine to rotate. The rotation of the turbine can continuously discharge the air inside the collection chamber, thereby creating a negative pressure inside the collection chamber, effectively adsorbing the tiny waste residue that falls off during the polishing process into the collection chamber, removing the waste residue in real time, and reducing secondary pollution.
[0016] 2. In this invention, when the device is in use, the steel pipe can be placed on the upper part of the fixed clamping plate, and then the second motor can be started. The second motor can drive the fixed component to perform transmission, thereby driving the movable clamping plate to press down and fix the steel pipe. Moreover, depending on the different specifications of the steel pipe, the polishing head can also be driven to rise and fall by the first cylinder, thereby ensuring that the polishing head and the steel pipe are coaxial and avoiding errors.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Example 1 like Figures 1-6 As shown, a stable internal positioning polishing device for spare plastic-lined stainless steel tubing includes a polishing table 1. A fixing mechanism is provided on the upper part of the polishing table 1 to clamp and fix a steel pipe 5. A polishing housing 7 is provided on the upper part of the polishing table 1. A first motor 10 is provided inside the polishing housing 7. A first gear 11 is provided at the output end of the first motor 10. The first gear 11 is meshed with a second gear 12. The second gear 12 is meshed with a third gear 13. An outer rod 15 is fixedly connected to the third gear 13. A collection chamber 9 is fixedly connected to the outer rod 15. An air suction cylinder 22 is fixedly connected inside the collection chamber 9. A polishing head 8 is provided at the front end of the collection chamber 9. An inner rod 14 is fixedly connected to the first gear 11. The inner rod 14 is rotatably connected to the outer rod 15. A turbine 23 is fixedly connected to the inner rod 14. The turbine 23 is rotatably connected to the collection chamber 9.
[0021] The first motor 10 is started, which drives the first gear 11 to rotate. The rotation of the first gear 11 drives the outer rod 15 to rotate, which in turn drives the collection chamber 9 to rotate, thereby driving the polishing head 8 to rotate, thus performing polishing treatment inside the steel pipe 5. At the same time, the rotation of the first gear 11 drives the inner rod 14 to rotate, which in turn drives the turbine 23 to rotate, thereby accelerating the entry of outside air into the collection chamber 9. This creates a negative pressure inside the collection chamber 9 to adsorb the waste residue generated during the polishing process. The surface of the air suction cylinder 22 is provided with micropores to effectively prevent waste residue from entering and obstructing the rotation of the turbine 23. The first gear 11, the second gear 12, and the third gear 13 have the same module, and the rotation direction of the third gear 13 is opposite to that of the first gear 11.
[0022] An air inlet 16 is provided at the rear end of the collection chamber 9 near the turbine 23. An adjustment mechanism is provided at the front end of the collection chamber 9. The adjustment mechanism includes a second air chamber 17 located on the upper part of the collection chamber 9. A slide plate 18 is provided at the output end of the second air chamber 17. An adjustment rod 19 is rotatably connected to the upper part of the slide plate 18. The adjustment rod 19 is rotatably connected to the polishing head 8. A connecting rod 20 is rotatably connected to the upper part of the polishing head 8. A spring 21 is sleeved on the outside of the adjustment rod 19. The spring 21 provides shock absorption for the polishing head 8.
[0023] In this embodiment, during use, the lifting platform 3 is activated to drive the polishing head 8 to rise and fall, thereby adjusting the polishing head 8 to align with its axis according to the specifications of the steel pipe 5. Then, the first cylinder 2 is activated to push the polishing head 8 into the interior of the steel pipe 5. During the polishing process, the first motor 10 is activated to drive the first gear 11 to rotate. The rotation of the first gear 11 drives the meshing second gear 12 to rotate. The rotation of the second gear 12 drives the meshing third gear 13 to rotate. The rotation of the third gear 13 drives the fixedly connected outer rod 15 to rotate. The rotation of the outer rod 15 drives the fixedly connected collection cavity 9 to rotate, which in turn drives the polishing head 8 at the front end to rotate. The rotation of the polishing head 8 can polish the interior of the steel pipe 5.
[0024] As the polishing head 8 continuously polishes the steel pipe 5, waste residue will continuously fall off during the process. The rotation of the first gear 11 can synchronously drive the fixedly connected inner rod 14 to rotate. The rotation of the inner rod 14 can drive the fixedly connected turbine 23 to rotate. The rotation of the turbine 23 can continuously discharge the air inside the collection chamber 9, thereby creating a negative pressure inside the collection chamber 9. This effectively adsorbs and collects the tiny waste residue that falls off during the polishing process into the collection chamber 9, removing the waste residue in real time and reducing secondary pollution.
[0025] A second air chamber 17 is provided at the front end of the collection chamber 9. By activating the second air chamber 17, the slide plate 18 can be moved. The movement of the slide plate 18 can cause the spring 21 to rotate, thereby causing the polishing head 8 to extend outward, effectively adapting to steel pipes 5 with different inner diameters, ensuring that the polishing head 8 fits the inner wall of the steel pipe 5. The spring 21 provided on the upper part of the adjusting rod 19 can provide shock absorption for the polishing head 8.
[0026] Example 2 like Figures 1-6 As shown, a first cylinder 2 is provided on the upper part of the polishing table 1, and a lifting platform 3 is provided at the output end of the first cylinder 2. The lifting platform 3 is slidably connected to the polishing table 1. A polishing housing 7 is provided on the upper part of the lifting platform 3. A limit structure is provided on the upper part of the lifting platform 3 to ensure stability during the lifting process. The fixing mechanism includes a fixing frame 4 fixedly connected to the upper part of the polishing table 1. A fixing clamp 24 is fixedly connected to the bottom of the fixing frame 4. A fixing housing 6 is fixedly connected to the top of the fixing frame 4. A second motor 27 is provided on one side of the fixing housing 6. A fixing component is provided at the output end of the second motor 27.
[0027] The fixed assembly includes a worm gear 28 at the output end of the second motor 27, a worm wheel 29 meshing with the worm gear 28, a fourth gear 30 fixedly connected to the worm wheel 29, a transmission rack 31 meshing with the fourth gear 30, a movable clamping plate 25 fixedly connected to the bottom of the transmission rack 31, a sliding connection between the movable clamping plate 25 and the slide groove 26, a fixed connection between the slide groove 26 and the fixed frame 4, a slider on the upper part of the movable clamping plate 25, which is slidably connected to the slide groove 26, anti-slip pads on the surfaces of both the fixed clamping plate 24 and the movable clamping plate 25, and a wedge-shaped structure for increasing the contact area with the surface of the steel pipe 5. A limiting groove 32 is fixedly connected inside the fixed housing 6, and the transmission rack 31 is slidably connected inside the limiting groove 32.
[0028] In this embodiment, before polishing, the steel pipe 5 can be placed on the upper part of the fixed clamping plate 24. After placement, the second motor 27 is started to drive the worm gear 28 to rotate. The rotation of the worm gear 28 drives the meshing worm wheel 29 to rotate. The rotation of the worm wheel 29 drives the fixedly connected fourth gear 30 to rotate. The rotation of the fourth gear 30 drives the meshing transmission rack 31 to move. During the movement of the transmission rack 31, the slidingly connected limiting groove 32 can ensure its stability during movement. The movement of the transmission rack 31 can drive the fixedly connected movable clamping plate 25 to press down, so that the clamping position can be adjusted according to the specifications of the steel pipe 5. During the pressing and fixing process of the movable clamping plate 25, the sliding grooves 26 on both sides can further ensure the stability of the fixing process and avoid the steel pipe 5 from vibrating during polishing, thereby affecting the polishing effect.
