Therefore, once an item is defined or described in one drawing, it will not be necessary to further discuss and describe it specifically in the description of the subsequent drawings.

[0032] To solve the technical problems in the background art, as Figures 1-5 shown, the present application provides a technical solution: a pipe positioning fixture, including:

[0033] The fixed seat 1 is made of a strong metal material and is provided with an arc-shaped groove 2 and a through hole 3. The arc-shaped groove 2 is designed to fit the first roller 5, and the through hole 3 is used for the first adjusting rod 9 to pass through. The T-shaped block 4 clamps the pipe processing table to ensure the stable fixation of the fixture during the processing. The T-shaped block 4 is an inverted T shape, the vertical rod part is inserted into the groove of the pipe processing table, and the horizontal rod part abuts against both sides beside the groove of the pipe processing table. The T-shaped block 4 is internally provided with a threaded hole for connecting with the first adjusting rod 9. When the first adjusting rod 9 is tightened, the T-shaped block 4 closely adheres to the pipe processing table to achieve the positioning of the entire pipe positioning fixture. The first roller 5 is adapted to the arc-shaped groove 2 and can roll along the arc-shaped groove 2 therein. The axial direction of the first roller 5 is parallel to the axial direction of the arc-shaped groove 2. The design of the first roller 5 enables the fixture to rotate around the axis of the first roller 5. The connecting rod 6 connects the first roller 5, and its length and strength are carefully designed to ensure stability and flexibility during operation. The second roller 7 is connected to the connecting rod 6, and a roller shaft 8 is arranged between the first roller 5 and the second roller 7. The design of the roller shaft 8 enables both the first roller 5 and the second roller 7 to rotate smoothly around the roller shaft 8. The first adjusting rod 9 passes through the through hole 3 of the fixed seat 1 and is threadedly connected to the roller shaft 8 and the T-shaped block 4. When the first adjusting rod 9 is loosened, the first roller 5 can rotate around the roller shaft 8. When it rotates to the appropriate position, tighten the first adjusting rod 9 to press the first roller 5, the roller shaft 8, and the fixed seat 1 against the T-shaped block 4 to complete the adjustment of the first position of the fixture.

[0034] The slider 10 has an arc-shaped surface 11 adapted to the second roller 7 and is provided with a through hole 12. The design of the arc-shaped surface 11 enables the second roller 7 to stably obtain support therein for rotating around the axis. The arc-shaped surface 11 is parallel to the axis of the second roller 7. The clamping block 13 is arranged on the slider 10 and has a central hole 14 and a clamping hole 15. The central hole 14 is coaxially arranged with the clamping block 13, and the clamping hole 15 is perpendicular to the axis of the clamping block 13 and is offset from the central hole 14. The second adjusting rod 16 passes through the central hole 14, the through hole 12, and the roller shaft 8 of the second roller 7 and is threadedly connected to the clamping block 13 for clamping. When the threaded connection between the second adjusting rod 16 and the clamping block 13 is loosened, the clamping block 13, the slider 10, the second roller 7, and the roller shaft 8 are loose, and the second adjusting rod 16 can be rotated around the axis of the roller shaft 8 to adjust the positions of the slider 10 and the second roller 7. At the same time, the clamping block 13 can also be rotated; when the second adjusting rod 16 is tightened, the clamping block 13, the slider 10, the second roller 7, and the roller shaft 8 are clamped and fixed. The pipe to be processed is passed through the clamping hole 15 of the clamping block 13 for clamping, so the setting of the clamping hole 15 is adapted to the diameter of the pipe.

[0035] Further, the clamping hole 15 is provided in the clamping block 13 for fixing the pipe material to ensure the stability of the pipe material during processing. In order to further improve the adaptability of the clamping hole 15 to pipe materials of different diameters and also to facilitate the insertion of the pipe material to be processed into the clamping hole 15, an adjustment groove 17 is provided beside the clamping hole 15. The adjustment groove 17 is arranged parallel to the clamping hole 15 and penetrates through the clamping block 13. When the pipe material needs to be inserted, the operator can loosen it through the second adjusting rod 16. After inserting the pipe material, tighten the second adjusting rod 16 to compress the adjustment groove 17, and the adjustment groove 17 shrinks, thereby clamping the pipe material to be processed.

[0036] Further, the hexagon socket is located in the middle part of the first adjusting rod 9 and is used in cooperation with an adjusting tool. The first adjusting rod 9 has an external thread. By using a tool to rotate the hexagon socket in cooperation, the tightening and loosening of the external thread of the first adjusting rod 9 can be achieved.

[0037] It should be noted that the second adjusting rod 16 has a hexagon socket at one end. The specific structure is as follows: The second adjusting rod 16 is a hollow cylindrical structure with an external thread. One end of it is provided with a hexagon socket, and the size of this socket matches that of a common hexagon wrench, which is convenient for installation and adjustment. The position of the hexagon socket is at one end of the second adjusting rod 16, and the depth is about 10 mm to ensure that the wrench can be firmly inserted into the socket for operation. The material of the second adjusting rod 16 is stainless steel, which has good strength and wear resistance and can meet the requirements of long-term use.

[0038] Further, the adjusting handle 18 is L-shaped, with one end being the handle part and the other end being the insertion part. The insertion part can be inserted into the hexagon socket of the second adjusting rod 16 as shown in the figure. When the operator holds the handle part of the adjusting handle 18 and applies force, the insertion part of the adjusting handle 18 will drive the second adjusting rod 16 to rotate.

[0039] It should be noted that the anti-slip layer is provided on the inner surface of the arc-shaped groove 2 to increase the friction and prevent the first roller 5 from sliding during clamping. The anti-slip layer is made of a material with good anti-slip performance, such as rubber, plastic, etc. The anti-slip layer is firmly set on the inner surface of the arc-shaped groove 2 through processes such as spraying, pasting, or injection molding. In order to improve the anti-slip performance, the surface of the anti-slip layer can be designed with structures such as protrusions and textures to increase the friction of the contact surface.

[0040] Further, the anti-slip layer is evenly coated on the surface of the arc-shaped surface 11 with a thickness of 2 mm. The anti-slip layer is made of rubber material and has excellent wear resistance and anti-slip performance. The anti-slip layer and the arc-shaped surface 11 are combined by an adhesive bonding method, and the adhesive is epoxy resin glue to ensure that the anti-slip layer is tightly combined with the arc-shaped surface 11 and is not easy to fall off. This prevents the second roller 7 from sliding during clamping.

[0041] Although embodiments of the present application have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
