[0022] The following description is merely illustrative in nature and is not intended to limit the present disclosure, its applications, or uses. It should be understood that throughout the drawings, identical or similar reference numerals indicate identical or similar parts and features. The drawings merely schematically illustrate the concepts and principles of the embodiments of the present disclosure and do not necessarily depict the specific dimensions and proportions of the various embodiments of the present disclosure. Certain portions of certain drawings may be exaggerated to illustrate relevant details or structures of the embodiments of the present disclosure.

[0023] Please see Figure 1-5 One embodiment provided by this utility model:

[0024] A stainless steel pipe inner wall polishing device includes a support frame 2, a top seat 3 fixedly installed at the top of the support frame 2, a limiting groove 913 opened on one side of the outer surface of the top seat 3, and a fixing plate 912 fixedly installed at the bottom of one side of the top seat 3. Two sets of support seats 4 are fixedly installed on both sides of one end of the top seat 3, and a clamping mechanism is provided at the top of the two sets of support seats 4 for fixing the stainless steel pipe 1. An installation groove 813 is opened at the bottom of the top seat 3, and a movable mechanism is provided in the installation groove 813. One end of the movable mechanism is connected to a linkage rod 911, and the linkage rod 911 is U-shaped. The linkage rod 911 passes through the inner wall of the limiting groove 913, and one end of the linkage rod 911 is connected to a connecting rod 713. Multiple sets of limiting mechanisms are provided on the outer surface of the connecting rod 713, and a first motor 8 is fixedly installed at one end of one set of limiting mechanisms. A grinding roller 7 is connected to one end of the first motor 8, and one end of the grinding roller 7 is conical.

[0025] Furthermore, the clamping mechanism includes a cylinder 5, which is fixedly installed on the top of the support base 4. One end of the cylinder 5 is connected to a clamping claw 6, which is used to clamp the stainless steel tube 1 to ensure the stability and firmness of the stainless steel tube 1 during the polishing process.

[0026] Furthermore, a retaining ring 914 is movably installed on the outer surface of the linkage rod 911, and multiple sets of retaining rods 915 are fixedly installed on the outer surface of the retaining ring 914. The multiple sets of retaining rods 915 are respectively connected to the top outer surface of the fixing plate 912 and the top seat 3. The retaining ring 914 is used to support the movement of the linkage rod 911, which helps to prevent the linkage rod 911 from shifting or deforming during the movement, thereby ensuring the accuracy and reliability of the polishing operation.

[0027] Furthermore, the movable mechanism includes two sets of fixed seats 815, and the outer surface of both sets of fixed seats 815 is provided with a circular through groove. A lead screw 812 is movably installed in the circular through groove, and one end of the lead screw 812 is connected to a second motor 816. The second motor 816 is fixedly connected to the fixed seat 815. A sliding seat 814 is movably installed on the outer surface of the lead screw 812, and one end of the sliding seat 814 is connected to a linkage rod 911. The lead screw 812 provides precise control over the polishing depth, which helps to improve the quality and efficiency of the polishing operation.

[0028] Furthermore, a protective plate 811 is fixedly installed on one side of the inner wall of the mounting groove 813, and a sliding groove is formed on the outer surface of the protective plate 811. A linkage rod 911 is movably engaged in the sliding groove. The protective plate 811 and the sliding groove provide additional guidance and protection for the movement of the linkage rod 911. This helps to prevent the linkage rod 911 from being damaged or deviating from the predetermined path during movement, thereby ensuring the smooth progress of the polishing operation.

[0029] Furthermore, the multiple limiting mechanisms include multiple limiting seats 9, which are cross-shaped. Each limiting seat 9 has a groove at one end, and multiple springs are installed in the grooves. One end of each spring is connected to a connecting frame 711, and a rotating wheel 712 is movably installed on the inner wall of the connecting frame 711. The limiting mechanisms support the movement of the first motor 8 within the stainless steel tube. The improved adaptability and stability of the connecting frame 711 due to the springs help ensure the uniformity and consistency of the polishing operation.

[0030] Furthermore, the outer surface of the rotating wheel 712 is covered with rubber. The rubber-covered rotating wheel 712 increases the friction between itself and the inner wall of the stainless steel tube, which helps to prevent the polishing tool from slipping or shifting during the polishing process.

[0031] Working principle: First, the operator activates cylinder 5 in the clamping mechanism. After receiving the signal, cylinder 5 extends its piston rod, pushing the clamping claw 6 closer to the stainless steel tube 1 and clamping it tightly, ensuring that the stainless steel tube 1 maintains a firm and stable position during the polishing process.

[0032] Next, the operator starts the second motor 816 of the movable mechanism in the mounting slot 813. The second motor 816 begins to rotate, driving the lead screw 812 connected to it to rotate synchronously. Since the lead screw 812 and the sliding seat 814 are threadedly connected, the rotation of the lead screw 812 is converted into linear movement of the sliding seat 814. During the movement, the sliding seat 814, through the transmission action of the linkage rod 911, drives the connecting rod 713 and its first motor 8 and grinding roller 7 to move closer to the inner wall of the stainless steel tube 1.

[0033] During the movement of the sliding seat 814, the linkage rod 911 moves stably under the guidance of the limiting groove 913 and the fixing ring 914. At the same time, the fixing rod 915 provides additional support to ensure that the linkage rod 911 will not deform or deviate due to excessive force.

[0034] Once the first motor 8 and the polishing roller 7 reach their designated positions, the operator starts the first motor 8. The first motor 8 begins to rotate, driving the polishing roller 7 to rotate synchronously. Because one end of the polishing roller 7 is conical, it can easily enter the inner wall of the stainless steel pipe 1 and perform polishing operations.

[0035] During the polishing process, the connecting frame 711 of the limiting mechanism, through the action of the spring, plays an adaptive role on the inner wall of the stainless steel tube 1. This ensures that the rotating wheel 712 is always tightly fitted to the inner wall of the stainless steel tube 1, providing stable support for the first motor 8.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
