[0002] Alloy steel pipes are steel pipes whose properties are improved by adding one or more alloying elements. They are widely used in scenarios that require high strength, corrosion resistance, high temperature resistance, or special physical and chemical properties. In the processing of alloy steel pipes, inner wall polishing is a key process to improve pipe performance, extend service life, and meet specific application requirements.

[0003] In the polishing process of alloy steel pipes, a corresponding polishing structure is usually installed on an electric guide rail. The electric guide rail drives the polishing structure to move horizontally. Polishing pipes of different specifications requires cumbersome adjustments, which means that it can only polish pipes of the same specification, but cannot meet the polishing requirements of pipes of different sizes. Therefore, an alloy steel pipe inner wall polishing device is proposed to solve the above problems. Utility Model Content

[0017] Alloy steel pipes are steel pipes whose properties are improved by adding one or more alloying elements. They are widely used in scenarios that require high strength, corrosion resistance, high temperature resistance, or special physical and chemical properties. In the processing of alloy steel pipes, inner wall polishing is a key process to improve pipe performance, extend service life, and meet specific application requirements.

[0018] In the polishing process of alloy steel pipes, a corresponding polishing structure is often installed on an electric guide rail. The electric guide rail drives the polishing structure to move horizontally. Polishing pipes of different specifications requires cumbersome adjustments, which means that it can only polish pipes of the same specification, but cannot meet the polishing requirements of pipes of different sizes.

[0019] Therefore, an alloy steel pipe inner wall polishing device is proposed to solve the above problems.

[0020] Please see Figure 1-3 The alloy steel pipe inner wall polishing device in this embodiment includes a first carrier 1, a second carrier 2, a rotating mechanism, a guiding mechanism, and a polishing mechanism. The second carrier 2 is located to the left of the first carrier 1. The rotating mechanism is located inside the second carrier 2 and is used to drive the alloy steel pipe to rotate. The guiding mechanism is located inside the second carrier 2 and is used to prevent the alloy steel pipe from axially displacing. The polishing mechanism includes a polishing component and an adjusting component. The adjusting component is used to drive the polishing component to move laterally and vertically. The polishing component is used to enter the alloy steel pipe on the rotating mechanism through the adjusting component and contact its inner wall for mechanical polishing.

[0021] Specifically, the adjustment component and polishing component are adjusted and matched vertically according to the wall thickness of the alloy steel pipe. The alloy steel pipe is placed on the rotating mechanism, and the guide mechanism contacts the alloy steel pipe for positioning. At this time, the adjustment component drives the polishing component to move laterally, enter the interior of the alloy steel pipe, and contact its inner wall to achieve polishing.

[0022] In this embodiment, the rotating mechanism includes a drive assembly 4 and two transmission rollers 3. The output end of the drive assembly 4 is connected to one transmission roller 3, and both transmission rollers 3 are mounted on the second carrier 2 via bearings.

[0023] Specifically, after the drive assembly 4 drives one transmission roller 3 to rotate, it drives another transmission roller 3 to rotate through the friction of the alloy steel pipe. Since the axes of the two transmission rollers 3 are parallel to the axis of the alloy steel pipe, they rotate on their own.

[0024] The drive assembly 4 includes a brushless motor, a drive wheel or sprocket, and a belt or chain. The drive wheel or sprocket is mounted on the shaft of the output end of the brushless motor and a drive roller 3, respectively, and is driven by the belt or chain to achieve the rotation of the alloy steel pipe.

[0025] In this embodiment, the guiding mechanism includes a linear slide rail 5 and two adjusting cylinders 10. The linear slide rail 5 and the two adjusting cylinders 10 are both fixed to the back of the second carrier 2. The linear slide rail 5 has two sliders. A support frame 6 is fixed to the top of each slider. An extension cylinder 7 is fixed to the extension end of the support frame 6. A U-shaped roller frame 8 is fixed to the output end of the extension cylinder 7. Two guide wheels 9 are arranged inside the U-shaped roller frame 8 through bearings. The output ends of the two adjusting cylinders 10 are respectively connected to the two sliders through connecting plates.

[0026] Specifically, after the alloy steel pipe is placed between the two transmission rollers 3, the two adjusting cylinders 10 are activated to drive the support frame 6 to move relative to or opposite to each other, to match the length of the alloy steel pipe. Then, the extension cylinder 7 is activated to drive the two guide wheels 9 to contact the alloy steel pipe via the U-shaped roller frame 8, thereby restricting the radial and axial degrees of freedom of the alloy steel pipe and further preventing the alloy steel pipe from deviating during rotation.

[0027] The connecting plate is an L-shaped plate, which allows the output end of the adjusting cylinder 10 to be easily fixed to the slider.

[0028] In this embodiment, the polishing assembly includes a drive unit 12, an extension shaft 13 is fixed to the output end of the drive unit 12, and a polishing wheel 14 is fixed to the left end of the extension shaft 13.

[0029] It should be understood that the drive unit 12 is a brushless motor, which is a DC motor that uses an electronic commutator to replace the traditional mechanical brush and commutator. It has significant advantages such as high efficiency, long life, low noise, and high power density. The brushless motor enables the extension shaft 13 to rotate stably, thereby driving the polishing wheel 14 to rotate stably and achieving precise control of the polishing wheel 14.

[0030] Specifically, when the polishing wheel 14 enters the interior of the alloy steel pipe, the drive unit 12 drives the polishing wheel 14 to grind and polish the inner wall of the alloy steel pipe via the extension shaft 13. At this time, the alloy steel pipe rotates, achieving rapid and stable polishing.

[0031] In this embodiment, the adjustment assembly includes a linear module 11 fixed inside the first carrier 1. A carrier frame 15 is fixed to the output end of the linear module 11. An intermediate plate 16 is fixed to the top of the carrier frame 15. Four vertical shafts 17 and a protective shell 18 are fixed to the top of the intermediate plate 16. An adjusting screw sleeve 19 and a worm gear 23 are arranged inside the protective shell 18 through bearings. A worm wheel 20 that meshes with the worm gear 23 is fixed to the outside of the adjusting screw sleeve 19. A movable screw 21 is threadedly installed inside the adjusting screw sleeve 19. A connecting plate 22 is rotatably installed on the top of the movable screw 21. The top of the connecting plate 22 is movably sleeved on the top plate 26 outside the four vertical shafts 17. A transmission rod 24 is fixed to the front of the worm gear 23. A handwheel 25 is fixed to the outside of the transmission rod 24. The drive unit 12 is fixed to the top of the top plate 26.

[0032] Specifically, rotating the handwheel 25 drives the worm gear 23 via the transmission rod 24, causing the worm wheel 20 meshing with it to rotate, thereby rotating the adjusting screw sleeve 19, which in turn drives the movable screw 21 to rotate inside it. Since the movable screw 21 is rotatably installed with the connecting plate 22, the top plate 26, which is limited by the four vertical shafts 17, can only move upward or downward, realizing the height adjustment of the drive part 12 on the top plate 26, thereby driving the height adjustment of the polishing wheel 14.

[0033] The worm 23 and worm wheel 20 have a self-locking function, so the weight of the drive unit 12 cannot drive the movable screw 21 or the adjusting screw sleeve 19 to rotate the worm wheel 20, thereby allowing the top plate 26 to be stably supported.

[0034] In addition, the protective shell 18 protects the worm 23 and worm wheel 20, preventing damage from the external environment and extending their service life.

[0035] In this embodiment, a controller 27 is fixed on the front of the second carrier 2. The controller 27 is electrically connected to the drive unit 12, the drive assembly 4, the linear module 11, the adjusting cylinder 10, and the extension cylinder 7.

[0036] It should be understood that the electrical connections of controller 27 enable the various electrical components to operate in a coordinated manner through controller 27.

[0037] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
