[0002] A round tube external polishing machine is a mechanical device specifically designed for polishing the outer surface of round tube workpieces. It is widely used in industries such as hardware manufacturing, pipe processing, furniture and building materials, and automotive parts. Its core function is to use mechanical motion to drive the polishing component into contact with the surface of the round tube, removing surface imperfections such as burrs, scratches, and rust, thereby improving the smoothness, flatness, and aesthetics of the outer surface of the round tube. Currently, round tube external polishing machines are widely used in industrial production; however, the installation and disassembly process of the polishing wheel is often quite cumbersome. Traditional polishing machines typically use bolts or clips to fix the polishing wheel, requiring multiple tightenings of bolts or precise alignment of clips during installation, which is time-consuming and inconvenient. Furthermore, after prolonged use, bolts are prone to rust and clips to wear, leading to difficulties in disassembly. Therefore, this utility model proposes a round tube external polishing machine to solve the above problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0018] Please see Figures 1 to 4This utility model provides a technical solution: a round tube outer diameter polishing machine, including a support plate 1, a transmission wheel 3, and a support connecting plate 11. A rotating column 10 is rotatably mounted on the support connecting plate 11. A mounting block 9 is fixedly connected to one end of the rotating column 10. A grinding wheel 5 is mounted on the mounting block 9. A fixing component 6 for fixing the grinding wheel 5 to the mounting block 9 is provided on the mounting block 9. A pushing component 7 is provided on the rotating column 10. The pushing component 7 includes a cylindrical groove 72 opened on the rotating column 10 and a sliding rod 73 that slides into the support connecting plate 11. A moving column 71 is fixedly mounted to one end of the sliding rod 73. A connecting spring 74 connects the moving column 71 and the support connecting plate 11. Equipped with a fixing component 6 and a pushing component 7, when installing the grinding wheel 5, it pushes the pull plate 62 against the inclined surface of the limiting slider 63, causing the sliding plate 61 to compress the return spring 65. When the limiting groove 66 of the grinding wheel 5 is aligned with the limiting slider 63, the return spring 65 pushes the sliding plate 61 to make the limiting slider 63 snap into the limiting groove 66 to complete the fixing. When installing the grinding wheel 5, it pushes the moving column 71 to cause the sliding rod 73 to compress the connecting spring 74. When disassembling, the connecting spring 74 elastically resets and pushes the moving column 71 to push the grinding wheel 5 out of the mounting block 9. The operation is convenient and efficient. Moreover, the cooperation between the rotating column 10 and the supporting connecting plate 11 ensures the stability of the grinding wheel 5 during installation and the smoothness of disassembly.
[0019] like Figure 3 as well as Figure 4 As shown, the fixing component 6 includes an internal groove 64 formed inside the mounting block 9. A sliding plate 61 is slidably connected inside the mounting block 9. A pull plate 62 is hinged to the sliding plate 61. A limiting slider 63 is hinged to the end of the pull plate 62 away from the sliding plate 61. The limiting slider 63 slides out of the mounting block 9. A return spring 65 is fixedly connected to one end of the sliding plate 61. The end of the return spring 65 away from the sliding plate 61 is fixedly connected to the inner wall of the internal groove 64. The grinding wheel 5 has a mounting groove 8 for the mounting block 9 to be inserted into. The grinding wheel 5 has a limiting groove 66 for the limiting slider 63 to extend into.
[0020] like Figure 3 As shown, one end of the grinding wheel 5 abuts against the moving column 71, the material guide groove 2 is fixedly installed on the support plate 1, and the cylindrical grooves 72 are arranged in a ring array on the rotating column 10.
[0021] When installing the grinding wheel 5, the mounting block 9 passes through the mounting groove 8 of the grinding wheel 5, and the grinding wheel 5 abuts against the inclined surface of the limiting slider 63, forcing the limiting slider 63 to drive the pull plate 62 to slide into the inner groove 64; when the grinding wheel 5 moves to the limiting groove 66 and aligns with the limiting slider 63, the return spring 65 returns to its original position and pushes the sliding plate 61, causing the limiting slider 63 to engage in the limiting groove 66, thus completing the fixing of the grinding wheel 5 on the mounting block 9. During this process, the grinding wheel 5 simultaneously contacts the moving column 71, pushing the moving column 71 to drive the sliding rod 73 to slide into the cylindrical groove 72, pressing... The connecting spring 74 is compressed until the grinding wheel 5 contacts the rotating column 10. At this time, the moving column 71 and the sliding rod 73 are completely retracted into the cylindrical groove 72, and the connecting spring 74 is in a compressed state. When disassembling the grinding wheel 5, the sliding plate 61 is pulled to move towards the inner groove 64. The pulling plate 62 drives the limiting slider 63 to retract into the mounting block 9, so that the limiting slider 63 is disengaged from the limiting groove 66, releasing the limitation on the grinding wheel 5. At this time, the compressed connecting spring 74 elastically resets, pushing the moving column 71 to push the grinding wheel 5 out of the mounting block 9, which facilitates quick disassembly and replacement.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
