Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, specifically a clamping tool for metal pipe processing. Background Technology

[0002] Metal pipes are hollow, long steel strips made primarily of metal materials through specific processes. In the construction industry, metal pipes are often used to build the frame structure of buildings, such as stair handrails and railings. They can also serve as water supply and drainage pipes to ensure the normal flow of water within buildings. In machinery manufacturing, they are the basic materials for manufacturing various mechanical parts, such as bearing sleeves and drive shafts, providing support for the normal operation of mechanical equipment.

[0003] When processing metal pipes, such as cutting, drilling, and turning, clamping tools can stably fix the pipes on the worktable of the processing equipment. In use, existing clamping tools usually clamp the outside of the pipe through clamping blocks, but the inner wall of the pipe cannot be clamped and supported. During the processing of metal pipes, such as turning and milling, the cutting force will cause the pipe to undergo slight deformation and displacement. Due to the lack of inner wall support, the pipe is prone to bending or twisting under force, resulting in deviations between the processed pipe dimensions and the design dimensions. Moreover, when adjusting the processing angle of the pipe, each adjustment requires first loosening the clamping tool, rotating the pipe, and then re-clamping it, which consumes a lot of time.

[0004] Therefore, it is necessary to provide a new clamping tool for metal tube processing to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a clamping tool for processing metal pipes, so as to solve the problems mentioned in the background art.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figure 1-5 As shown, a clamping tool for processing metal pipes includes a support plate 1 and a support base 2. The support base 2 is fixed to the top of the support plate 1, and a fixed base 3 is fixed to the top of the support base 2. A guide rod 4 is slidably connected to the inner wall of the fixed base 3. A first support block 5 for supporting the inner wall of the pipe is fixed to one end of the guide rod 4. By sliding the guide rod 4 inside the fixed base 3, the first support block 5 is pushed to move, so that the first support block 5 supports and clamps the inner wall of the metal pipe, thereby improving the stability during pipe processing.

[0026] The first motor 6 is fixed to the inner wall of the support base 2, and the output end of the first motor 6 passes through the bottom of the inner cavity of the fixed base 3. The output end of the first motor 6 is fixed with a connecting plate 7, and the top of the connecting plate 7 is fixed with a driving block 8 that drives the guide rod 4 to move. The first motor 6 can drive the connecting plate 7 and the driving block 8 to rotate. The driving block 8 pushes the guide rod 4 to slide inside the fixed base 3, thereby driving the first support block 5 to move.

[0027] A base 10 is located at the bottom of a support plate 1. An mounting plate 11 is fixed to the inner wall of the base 10. A housing 12 is fixed to the top of the mounting plate 11. A driving component 9 is located inside the housing 12. A rotating rod 13 is located on the top of the driving component 9 to rotate the clamped pipe. The top of the rotating rod 13 is fixedly connected to the bottom of the support plate 1, and the outer side of the rotating rod 13 is rotatably connected to the inner wall of the housing 12. The driving component 9 can drive the rotating rod 13 to rotate, thereby causing the support plate 1 and the clamped pipe to rotate, achieving the effect of adjusting the processing angle of the pipe.

[0028] A guide rod 14 is fixed to the inner wall of the fixed base 3, and the outer side of the guide rod 14 is slidably connected to the inner wall of the drive block 8. When the connecting plate 7 drives the drive block 8 to rotate, it will drive the drive block 8 to slide on the outer side of the guide rod 14, thereby limiting the drive block 8 and improving its stability. One end of the guide rod 4 is fixed with a mounting block 15, and the outer side of the mounting block 15 is engaged with the inner wall of the first support block 5. The inner wall of the first support block 5 is threaded with a mounting bolt 16 for limiting the mounting block 15, thereby securing the first support block 5 on the outer side of the mounting block 15. The mounting bolt 16 is used to fix the first support block 5 on the outer side of the mounting block 15, thereby supporting the first support block 5 and facilitating the subsequent replacement of the first support block 5 with different sizes.

[0029] A cover plate 17 is installed on the top of the fixed base 3. The inner wall of the cover plate 17 is threaded with a fixing bolt 18. The cover plate 17 is fixed to the top of the fixed base 3 by the fixing bolt 18 to protect the inside of the fixed base 3.

[0030] A rod 19 is inserted into the inner wall of the first support block 5. A second support block 20 for supporting the inner wall of a longer pipe is fixed to the top of the rod 19. Anti-slip pads 21 are provided on the outer sides of both the second support block 20 and the first support block 5. The second support block 20 can be installed by inserting the rod 19 into the inside of the first support block 5. This is used to support the inner wall of a longer pipe, expanding the applicability of the clamping tool to pipes of different lengths. The inner wall of the second support block 20 can also be fitted with rods 19, allowing for the installation of different numbers of second support blocks 20. The anti-slip pads 21 are made of rubber, which increases the friction between the support block and the inner wall of the pipe, preventing the pipe from sliding during processing and improving the stability of the clamping.

[0031] A connecting frame 26 is fixed to the top of the support plate 1. A guide frame 22 is slidably connected to the inner wall of the connecting frame 26. A limiting block 23 for limiting the outer side of the pipe is fixed to one side of the guide frame 22. Pulling the guide frame 22 to slide inside the connecting frame 26 allows the limiting block 23 to clamp and limit the outer side of the pipe, further improving the stability of the pipe during processing. A protective pad 24 is provided on the inner wall of the limiting block 23. A limiting bolt 25 for limiting the guide frame 22 is threadedly connected to the inner wall of the connecting frame 26. The protective pad 24 is made of rubber and protects the pipe, preventing direct contact between the limiting block 23 and the pipe and causing damage to the pipe surface. It also increases the friction between the limiting block 23 and the pipe, improving the limiting effect. The limiting bolt 25 is used to limit the guide frame 22. After the guide frame 22 is adjusted to the appropriate position, tightening the limiting bolt 25 can fix the position of the guide frame 22 and the limiting block 23, ensuring the stability of the limiting.

[0032] The driving component 9 includes a second motor 91 fixed to one side of the housing 12. A worm gear 92 is fixed to the output end of the second motor 91. A worm wheel 93 for driving the rotating rod 13 to rotate is meshed on the outer side of the worm gear 92. The axis of the worm wheel 93 is fixedly connected to the outer side of the rotating rod 13. Starting the second motor 91 can drive the worm gear 92 to rotate the worm wheel 93, which in turn drives the rotating rod 13 to rotate. This causes the rotating rod 13 to drive the support plate 1 to rotate, thereby realizing the rotation of the support plate 1 and the pipe clamped above it, and improving the pipe processing range.

[0033] Working Principle: When using this device, the pipe is placed outside the support base 2. The first motor 6 drives the connecting plate 7 and the drive block 8 to rotate. The drive block 8 pushes the guide rod 4 to slide inside the fixed base 3. The sliding of the guide rod 4 inside the fixed base 3 pushes the first support block 5 to move, thus supporting and clamping the inner wall of the metal pipe, improving the stability during pipe processing. When the connecting plate 7 drives the drive block 8 to rotate, it causes the drive block 8 to slide outside the guide rod 14, limiting its movement and improving its stability. The first support block 5 is then secured to the outside of the mounting block 15 using mounting bolts 16, providing support for the first support block 5 and facilitating subsequent replacement with different sizes. Inserting the insertion rod 19 into the first support block 5 allows for the installation of the second support block 20, used to support the inner wall of longer pipes, expanding the applicability of the clamping tool to pipes of different lengths. The inner wall of the second support block 20 can also be fitted with the insertion rod 19, allowing for... Different numbers of second support blocks 20 are installed. Anti-slip pads 21, made of rubber, increase the friction between the support blocks and the inner wall of the pipe, preventing the pipe from sliding during processing and improving clamping stability. The guide frame 22 slides inside the connecting frame 26, causing the limiting block 23 to clamp and limit the outer side of the pipe, further improving the stability during pipe processing. Protective pads 24, also made of rubber, protect the pipe, preventing direct contact between the limiting block 23 and the pipe from causing surface damage, while also increasing the friction between the limiting block 23 and the pipe. The friction between them improves the limiting effect. The limiting bolt 25 is used to limit the guide frame 22. After the guide frame 22 is adjusted to the appropriate position, tightening the limiting bolt 25 can fix the position of the guide frame 22 and the limiting block 23, ensuring the stability of the limiting. Starting the second motor 91 can drive the worm gear 92 to rotate the worm wheel 93, so that the worm wheel 93 drives the rotating rod 13 to rotate, thereby driving the support plate 1 to rotate, thus realizing the rotation of the support plate 1 and the pipe clamped above, and improving the pipe processing range.
