Description

Technical Field

[0001] This utility model relates to the field of pipe polishing technology, and in particular to a steel pipe surface polishing machine. Background Technology

[0002] Steel pipe surface polishing is a metal surface treatment process primarily used to improve the appearance quality and extend the service life of steel pipes. This process removes burrs, scale, and rust from the steel pipe surface using physical or chemical methods, resulting in a smooth and bright surface. Physical polishing typically uses grinding wheels, abrasive belts, or polishing machines. Polished steel pipes not only have a more aesthetically pleasing appearance but also effectively prevent corrosion, making them widely used in construction, petroleum, and chemical industries.

[0003] When polishing steel pipes, the process usually involves manual contact between the steel pipe and the grinding wheel, which results in uneven polishing even though the surface of the steel pipe can be polished.

[0004] Therefore, a steel pipe surface polishing machine is proposed to solve or alleviate the above problems. Utility Model Content

[0028] A steel pipe surface polishing machine, such as Figures 1 to 4As shown, it includes a worktable 1, a primary servo motor 2 and a secondary servo motor 4 fixedly connected to the worktable 1 and arranged on the same side, a lateral limiting component arranged on the worktable 1 and relative to the primary servo motor 2 and the secondary servo motor 4, and a flexible support component located between the lateral limiting component and the primary servo motor 2. The lateral limiting component can adjust the distance between itself and the primary servo motor 2 and the secondary servo motor 4.

[0029] A primary grinding wheel 3 is coaxially fixedly connected to the output shaft of the primary servo motor 2, and a secondary grinding wheel 5 is coaxially fixedly connected to the output shaft of the secondary servo motor 4. Both the primary servo motor 2 and the secondary servo motor 4 are fitted with a cover 6 located on the outer ring of their output shafts. The cover 6 on the primary servo motor 2 is fitted outside the primary grinding wheel 3, and the cover 6 on the secondary servo motor 4 is fitted outside the secondary grinding wheel 5.

[0030] The flexible support assembly includes two sets of hinge seats 7 fixedly connected to both ends of the workbench 1 along its length, a drive roller 14 rotatably connected between the same set of hinge seats 7, and a support ring belt 8 sleeved on the outside of the two drive rollers 14, with the support ring belt 8 being taut.

[0031] The lateral limiting assembly includes several support seats 12 that can be displaced along the width direction of the worktable 1, a ball seat 15 fixedly connected to the side of the support seat 12 facing the first-stage servo motor 2 and the second-stage servo motor 4, an abutment ball 16 movably disposed within the ball seat 15, a fixed seat 9 fixedly connected to the worktable 1, and a guide rail 10 fixedly connected to the worktable 1 with its length direction consistent with the width direction of the worktable 1. The lateral limiting assembly also includes a spring telescopic rod 13 fixedly connected between the fixed seat 9 and the support seat 12, a slide seat 11 slidably connected to the guide rail 10, and the support seat 12 fixedly connected to the slide seat 11.

[0032] When using this polishing machine, the steel pipe is simply placed on the support ring 8 of the flexible support assembly. Because the support ring 8 itself is flexible, the steel pipe will not rigidly collide / rub against the worktable 1 or other structures when it is placed on it and pulled along its length, thus preventing surface damage. During this process, the spring telescopic rod 13, using the fixed seat 9 as the force point, applies a force to the support seat 12 towards the primary servo motor 2 and the secondary servo motor 4, causing the support seat 12 to move along the guide rail 10. The support seat 12 moves along the length direction, allowing the ball seat 15 to move towards the first-stage servo motor 2 and the second-stage servo motor 4. In this way, the contact ball 16 on the ball seat 15 can make point contact with the surface of the steel pipe, ensuring that the steel pipe can not only rotate but also move during rotation. The contact ball 16 reduces the contact area with the steel pipe. At the same time, the lateral limiting component can apply a force to the steel pipe towards the first-stage grinding wheel 3 and the second-stage grinding wheel 5, so that the steel pipe can be subjected to more uniform force when in contact with the first-stage grinding wheel 3 and the second-stage grinding wheel 5, and uneven grinding will not occur.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
