The polishing head is used to polish the inner wall of the stainless steel pipe, the transmission device drives the polishing head to rotate or move, the adjustment mechanism adjusts the polishing parameters, and the frame supports the overall structure. Together, they achieve efficient polishing of the inner surface of the stainless steel pipe.

[0004] In existing technologies, polishing requires operators to load and unload stainless steel pipes, fix their positions, and process them individually, which is time-consuming and difficult to meet the needs of large-scale orders, easily delaying the construction period. Long-term operation can also lead to operational errors due to fatigue, affecting product quality. Therefore, a stainless steel pipe inner surface polishing machine is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0033] 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.

[0034] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a stainless steel pipe inner surface polishing machine, comprising a base 1, with a loading platform 2 fixedly connected to the top of the base 1. The top of the loading platform 2 has a large slot capable of accommodating a large number of stainless steel pipes. A drive assembly for providing loading driving force is installed inside the loading platform 2. The drive assembly includes a motor 3, which is externally mounted on the inner wall of the loading platform 2. The loading platform 2 serves to mount the external motor 3. A rotating shaft 5 is fixedly connected to the drive end of the motor 3. When the motor 3 is started, the rotation of the drive end of the motor 3 drives the rotating shaft 5 to rotate.

[0035] The drive assembly is externally fixedly connected to a feeding shaft 4, and the inner wall of the feeding shaft 4 is fixedly connected to the outside of a rotating shaft 5. The rotation of the rotating shaft 5 can drive the feeding shaft 4 to rotate. The feeding shaft 4 is externally rotatably connected to the inner wall of the feeding platform 2. Multiple bayonets are provided on the outside of the feeding shaft 4, so that the stainless steel pipe can rotate and be transported along the bayonets as the feeding shaft 4 rotates.

[0036] Reference Figure 2 , Figure 3 and Figure 6 A pulley 6 is externally fixed to the drive assembly. The pulley 6 is externally fixed to the outside of the rotating shaft 5, and rotation of the rotating shaft 5 drives the pulley 6 to rotate. A linkage shaft 8 is rotatably connected to the inner wall of the base 1. A movable plate 9 is externally fixed to the linkage shaft 8, and rotation of the linkage shaft 8 drives the movable plate 9 to rotate around the center of the linkage shaft 8. A linkage plate 10 is rotatably connected to the other end of the movable plate 9, and positional changes in the movable plate 9 drive positional changes in the linkage plate 10. A lifting plate 11 is rotatably connected to the other end of the linkage plate 10, and positional changes in the linkage plate 10 cause the lifting plate 11 to rise or fall.

[0037] A pulley 7 is fixedly connected to the outside of the connecting shaft 8. The rotation of pulley 7 drives the connecting shaft 8 to rotate. A belt 21 is fitted around the outside of pulley 6 and pulley 7, so that the rotation of pulley 6 can drive the rotation of pulley 7. Multiple telescopic columns 13 are fixedly connected to the bottom of the lifting plate 11. The other ends of the telescopic columns 13 are fixedly connected to the inner wall of the base 1, so that the lifting plate 11 can be supported by the position of the telescopic columns 13 during the position change. Two support plates 12 are fixedly connected to the top of the lifting plate 11. The position change of the lifting plate 11 can drive the position change of the two support plates 12. A steel pipe body 18 is slidably connected to the top of the two support plates 12. When the support plates 12 rise, they can lift the steel pipe body 18, which is convenient for the internal polishing of the steel pipe body 18.

[0038] Reference Figure 2 , Figure 4 and Figure 5 A second motor 14 is mounted on the top of the base 1. A telescopic rod 16 is fixedly connected to the drive end of the second motor 14. Starting the second motor 14 causes the drive end of the second motor 14 to rotate, thus moving the telescopic rod 16. A threaded rod 17 is fixedly connected to the other end of the telescopic rod 16. Rotation of the telescopic rod 16 causes the threaded rod 17 to rotate. A polishing tool 19 is mounted on the other end of the threaded rod 17. Rotation and positional changes of the threaded rod 17 cause the polishing tool 19 to process the inner wall of the steel pipe 18. A positioning tube 15 is fixedly connected to the top of the base 1. The telescopic rod 16 is externally slidably connected to the inner wall of the positioning tube 15, and the threaded rod 17 is externally threadedly connected to the inner wall of the positioning tube 15. This allows the threaded rod 17 to move along the inner wall of the positioning tube 15, thus enabling the telescopic rod 16 to extend and retract, thereby maintaining the continuous rotational power of the second motor 14. A conveyor belt 20 is mounted on the top of the base 1 for loading and unloading the steel pipe 18.

[0039] Working principle: Multiple stainless steel tubes are inserted into the loading platform 2. Then, motor 3 is started. The rotation of motor 3 drives the rotating shaft 5 to rotate, which in turn causes the loading shaft 4 to rotate. During the rotation of the loading shaft 4, the multiple stainless steel tubes engage with the outside of the loading shaft 4, allowing them to move in position one by one as the loading shaft 4 rotates. This allows the stainless steel tubes to fall onto the top of the conveyor belt 20 for transport. The rotation of the rotating shaft 5 drives pulley 6 to rotate, which, through belt 21, causes pulley 7 to rotate. The rotation of pulley 7 causes the connecting shaft 8 to rotate. The moving shaft 8 can drive the moving plate 9 to change position. The position change of the other end of the moving plate 9 can cause the position of the linkage plate 10 to change, thereby causing the lifting plate 11 to move upward. This causes the support plate 12 to move upward and lift a stainless steel pipe. After processing, the stainless steel pipe can move downward along the support plate 12, so that the stainless steel pipe falls on the top of the conveyor belt 20 and is continued to be transported. The simultaneous feeding of most stainless steel pipes and individual processing and unloading can improve production efficiency, meet the needs of large-scale orders, shorten the construction period, rationally arrange the production process, reduce waiting time, and reduce the risk of fatigue errors caused by long-term operation.

[0040] When motor 14 is started, the position change of the drive end of motor 14 causes the telescopic rod 16 to rotate. The position change of the telescopic rod 16 causes the threaded rod 17 to rotate, so that the outer part of the threaded rod 17 can move along the inner wall of the positioning tube 15. The position change of the threaded rod 17 can cause the polishing tool 19 to move along the inner wall of the steel pipe body 18, thereby achieving precise grinding and polishing of the inner wall of a single steel pipe. This makes the inner surface smooth, reduces fluid transport resistance, reduces media residue and wall adhesion, facilitates cleaning, prevents bacterial growth, and also enhances the corrosion resistance of the inner wall of the steel pipe, extending its service life.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
