[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0027] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale; for example, the thickness or width of some layers may be exaggerated relative to other layers.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0029] In order to solve the technical problems in the background art, such as Figure 1-3 As shown, this application provides a technical solution: a stainless steel pipe positioning mechanism, characterized as follows:

[0030] The worktable 1 is a rectangular structure made of a hard metal such as stainless steel, providing high stability and wear resistance. Multiple fixing holes 2 are provided on the worktable 1. These holes can be open or partially closed. The fixing holes 2 are used to connect to the fixing base 3. The fixing base 3 is made of the same material as the worktable 1 and its shape is not limited; it can be a rectangular plate, circular, or fan-shaped, and is positioned parallel to the worktable 1. The fixing base 3 has a through hole 4, which is coaxial with the fixing holes 2 on the worktable 1. The rotating shaft 5 is made of metal and fits into both the through hole 4 and the fixing hole 2, allowing free rotation within both holes. One end of the rotating arm 6 is fitted onto the rotating shaft 5 and rotates with it. The other end of the rotating arm 6 is hinged to a fastening clamp 7, which is used to clamp stainless steel pipes. The fastening clamp 7 can vary depending on the diameter of the workpiece to be clamped. A disc 8 is fixed to the rotating shaft 5 and rotates with it. A limiting block 9 is hinged to the fixing base 3. When the limiting block 9 rotates around the hinge axis, it can abut against the disk 8, thus restricting the rotation of the disk 8.

[0031] In use, place the stainless steel pipe on the workbench 1 and adjust the position of the fastening clamp 7 to hold the stainless steel pipe. Operate the rotating shaft 5 to make the rotating arm 6 rotate with the rotating shaft 5, thereby adjusting the fastening clamp 7 to hold the stainless steel pipe in the desired position. Further adjust the limit block 9 to abut against the disc 8 to restrict its rotation and ensure accurate positioning of the stainless steel pipe.

[0032] It should be noted that two limiting blocks 9 are further provided on the fixed base 3, and these two limiting blocks 9 are evenly arranged along the circumference of the disc 8. Specifically, the two limiting blocks 9 are respectively located on the side of the disc 8 and are connected to the fixed base 3 through hinge shafts. At the end of the two limiting blocks 9 away from the disc 8, a spring 10 is provided. The two ends of the spring 10 abut against the two limiting blocks 9 respectively, and its function is to limit the abutment position between the limiting blocks 9 and the disc 8. When the limiting blocks 9 are in contact with the disc 8, the elastic force generated by the spring 10 keeps the limiting blocks 9 in the abutment position, thereby ensuring that the rotation of the disc 8 is effectively limited. In use, pressing the end of the two limiting blocks 9 away from the disc 8 compresses the spring 10, causing the two limiting blocks 9 to rotate around their respective hinge shafts, thereby moving the abutment end away from the disc 8 and releasing the limiting effect. Once the disc 8 begins to rotate with the shaft 5, and the rotating arm 6 rotates to the desired position, the two limiting blocks 9 are released. The spring force of the spring 10 causes the two limiting blocks 9 to rotate around their respective hinge axes and then abut against the disc 8. This abutting action effectively limits the rotation range of the disc 8, prevents it from rotating excessively, and ensures the safe operation of the system.

[0033] Furthermore, a grip 11 is disposed at one end of the rotating shaft 5. The main body of the grip 11 is made of high-strength, wear-resistant material to ensure that it is not easily worn during use and to improve its service life; the surface of the grip 11 is provided with anti-slip texture to increase friction when gripping and prevent the operator's hand from slipping.

[0034] It should be noted that the grip 11 is cylindrical in shape for easy hand grip. The groove 12 is located on the side of the grip 11 and is semi-circular in shape. The diameter of the groove 12 is about 1 / 4 of the diameter of the grip 11. The function of the groove 12 is to increase the contact area between the grip 11 and the fingers, thereby improving grip comfort.

[0035] Furthermore, an anti-slip layer 13 is disposed at the end where the limiting block 9 abuts against the disc 8. The main function of the anti-slip layer 13 is to increase the friction between the disc 8 and the limiting block 9, preventing the disc 8 from sliding during rotation. The anti-slip layer 13 is preferably made of rubber material, which has good wear resistance and friction. The anti-slip layer 13 is sleeve-shaped and is fitted onto the limiting block 9.

[0036] It should be noted that the rubber layer 14 (not shown in the figure) is located inside the fastening clamp 7 and is used to contact the stainless steel pipe. The rubber layer 14 is made of a rubber material with good wear resistance and corrosion resistance, and its thickness is 2-5 mm. The rubber layer 14 effectively reduces friction between the fastening clamp 7 and the stainless steel pipe, preventing damage to the stainless steel pipe during the fastening process. The shape of the rubber layer 14 matches the shape of the inner side of the fastening clamp 7 to ensure full contact with the stainless steel pipe.

[0037] It should be noted that a keyway 15 is provided on the rotating shaft 5. The position and shape of the keyway 15 match the flat key 16 on the rotating arm 6 to ensure that the rotating arm 6 can be firmly connected to the rotating shaft 5. Specifically, the keyway 15 is a rectangular groove, its width is slightly larger than the width of the flat key 16, and its length is sufficient to accommodate the entire flat key 16. The shape and size of the keyway 15 are reasonably designed to ensure that the rotating arm 6 will not slip relative to the shaft during connection, thereby improving the overall stability and reliability.

[0038] It should be noted that the center of the sector-shaped fixing seat 3 coincides with the center of the rotating shaft 5, meaning they share the same center. As shown in the figure, the edge of the sector-shaped fixing seat 3 is also provided with a fixing structure that connects to the worktable 1. This structural design improves the overall stability of the sector-shaped fixing seat 3.

[0039] It should be noted that the disk 8 is a rotating component with a central rotating shaft, and several limiting blocks 9 are provided on the edge of the disk 8. Specifically, the angle θ formed by the lines connecting the contact points of two limiting blocks 9 with the disk 8 and the center of the disk 8 is greater than 15 degrees, preferably 20 degrees. The two limiting blocks 9 with such an angle can effectively restrict the movement of the disk 8.

[0040] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
