Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-5 , a clamping tool for a metal pipe welding platform, including a tooling bottom plate 1 and a receiving table 2. The receiving table 2 is fixedly installed on the tooling bottom plate 1. The receiving table 2 is used for clamping the placement of metal pipes. It also includes a clamping table 3. Clamping tables 3 are provided on both sides of the receiving table 2. The clamping table 3 includes a lifting column 31, a threaded rod 32, a locking screw 33, an extension rod 34, a clamping seat 35, and a docking seat 36. The bottom end of the lifting column 31 is fixedly connected to the threaded rod 32. The threaded rod 32 is inserted into the tooling bottom plate 1. When the height of the threaded rod 32 is appropriate, it is locked to the tooling bottom plate 1 by two nuts on the threaded rod 32. The extension rod 34 is inserted into the lifting column 31, and the extension rod 34 can rotate in the lifting column 31. A locking screw 33 is inserted into one side of the extension rod 34. A clamping seat 35 is provided on the extension rod 34. A docking seat 36 is provided at the top end of the lifting column 31. An activity groove 342 is opened inside the extension rod 34, and the clamping seat 35 can slide in the activity groove 342. When the clamping seat 35 slides, it drives the clamping rod 353 to move synchronously, and can be adjusted by driving the clamping rod 353 to move through the clamping seat 35 according to the size of the metal pipe.

[0021] Furthermore, the extension rod 34 further includes a rod body 341. There are two rod bodies 341 in total, which are respectively inserted into the lifting column 31 and the docking seat 36. The rod body 341 is movably connected to the lifting column 31, and is fixedly connected to the docking seat 36. At the same time, the rod body 341 is movably connected to the lifting column 31. The rod body 341 can rotate in the lifting column 31. The rod body 341 is penetrated by the locking screw 33, and the rod body 341 is threadedly connected to the locking screw 33.

[0022] Furthermore, the clamping seat 35 includes a moving base 351, a limiting convex plate 352, a clamping rod 353, and an external thread 354. A limiting convex plate 352 is provided on the outside of the moving base 351, and the limiting convex plate 352 is fixedly connected to the moving base 351. A clamping rod 353 is provided inside the moving base 351. The upper half of the clamping rod 353 is provided with an external thread 354. A nut is provided on the outside of the external thread 354. When the nut is rotated and locked to the rod body 341, the positions of the moving base 351 and the clamping rod 353 are fixed at the same time.

[0023] Further, the docking base 36 includes a docking frame 361, a hexagonal prism 362, a movable negative film 363, an embedded threaded post 364, and a connection base 365. The inside of the docking frame 361 is provided with a hexagonal prism 362. Below the hexagonal prism 362 is provided a movable negative film 363. The movable negative film 363 is penetrated by the embedded threaded post 364, and the embedded threaded post 364 is fixedly connected to the movable negative film 363. The outside of the embedded threaded post 364 is provided with a connection base 365. The embedded threaded post 364 can rise within the connection base 365 through a threaded structure. Due to the fixed connection between the embedded threaded post 364 and the movable negative film 363, the rise of the embedded threaded post 364 drives the movable negative film 363 to rise, and the movable negative film 363 lifts the hexagonal prism 362 upward.

[0024] Further, two clamping rods 353 are provided inside each moving base 351. The two clamping rods 353 are of different lengths. And outside the external thread 354 on the upper half of each clamping rod 353, there is a locking nut, which can adjust the height of the clamping rod 353 to clamp and fix the metal pipe.

[0025] Working principle: For a clamping tool for a metal pipe welding platform of the present utility model, during use, the threaded rod 32 is movably inserted on the tooling base plate 1 and locked by a nut. The moving base 351 is pushed to slide in the moving groove 342 inside the rod body 341 through the limiting convex plate 352. When the moving base 351 moves to a suitable position, the length of the clamping rod 353 is adjusted through the threaded connection between the external thread 354 on the clamping rod 353 and the moving base 351. After the four clamping rods 353 clamp and position the metal pipe, the position of the clamping rod 353 is locked and positioned by a nut. When the nut is locked, the position of the moving base 351 is also positioned. When it is necessary to adjust the locking height of the metal pipe, the extension rod 34 located below can be flipped and then locked and fixed by the locking screw 33. The embedded threaded post 364 is rotated. The embedded threaded post 364 rises within the connection base 365 through a threaded structure, driving the movable negative film 363 to rise, and at the same time driving the hexagonal prism 362 to rise. The metal pipe can be inserted between the two extension rods 34, and then the metal pipe is clamped by the same method as above.

[0026] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
