[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4 This utility model provides an embodiment of a positioning mechanism for a seamless steel pipe troweling machine, including a rotating disk 1, a support body 4, and a limiting block 5. It also includes an mounting block 21, a connecting block 23, a clamping plate 24, and an adjusting mechanism. The support body 4 is rotatably connected to the outside of the rotating disk 1, and the limiting block 5 is fixedly connected to the bottom of the support body 4. An adjusting mechanism is provided inside the rotating disk 1. The mounting block 21 is slidably connected inside the rotating disk 1, and the connecting block 23 is slidably connected inside the mounting block 21. The clamping plate 24 is fixedly connected to the inner side of the connecting block 23. The clamping plate 24 can be removed and replaced inside the mounting block 21 via the connecting block 23. The position of the connecting block 23 can be positioned by a locking block 25. The locking block 25 can be disengaged from the connecting block 23 by a first threaded rod 28, allowing the connecting block 23 to be removed from inside the mounting block 21. The clamping plate 24 is replaced to accommodate a clamping plate 24 of the corresponding seamless pipe size and shape. By turning the internal hex wrench to rotate the internal hex rotating block 32, the threaded cylinder 31 is rotated, and the second threaded rod 33 is unscrewed. This causes the mounting block 21 to slide through the connecting plate 22. The clamping plate 24 holds the seamless pipe in place. The mounting block 21 has a groove at the corresponding position of the connecting block 23, and the connecting block 23 slides inside the groove. The groove initially positions the connecting block 23 and restricts its position. Then, the locking block 25 is used to fix the connecting block 23. The rotating disk 1 has a groove at the corresponding position of the mounting block 21, and the mounting block 21 slides inside the groove. The groove limits the mounting block 21, preventing it from sliding out of the groove.

[0022] Please see Figures 1-3In this embodiment, a connecting plate 22 is fixedly connected to the back of the mounting block 21, a locking block 25 is slidably connected inside the mounting block 21, a spring 26 is fixedly connected between the locking block 25 and the mounting block 21, a sliding rod 27 is rotatably connected to the outside of the locking block 25, and a first threaded rod 28 is fixedly connected to the outside of the sliding rod 27. The mounting block 21 positions the connecting block 23, and the locking block 25 can be used to quickly replace the positioning connecting block 23. The clamping plate 24 can then be replaced according to the seamless pipe. The mounting block 21 has threaded holes at the corresponding positions of the sliding rod 27 and the first threaded rod 28, and the first threaded rod 28 is threadedly connected inside the threaded hole. The sliding rod 27 is movably connected inside the threaded hole. The position of the locking block 25 can be positioned by connecting the first threaded rod 28 to the threaded hole, and the locking block 25 can be pulled back directly by unscrewing the first threaded rod 28.

[0023] Please see Figure 1 , Figure 4 In this embodiment, the adjusting mechanism includes a threaded cylinder 31, which is rotatably connected to the inside of the rotating disk 1. An internal hexagonal rotating block 32 is fixedly connected to the outside of the threaded cylinder 31. A second threaded rod 33 is threadedly connected to the inside of the threaded cylinder 31 and is fixedly connected to the outside of the connecting plate 22. A first bevel gear 34 is fixedly connected to the outside of the threaded cylinder 31, and a second bevel gear 35 meshes with the outside of the first bevel gear 34. The second bevel gear 35 is rotatably connected to the inside of the rotating disk 1. By rotating the second bevel gear 35 of the first bevel gear 34, the three first bevel gears 34 can rotate synchronously, which can synchronously adjust the clamping of the seamless steel pipe by the three clamping plates 24. The rotating disk 1 has a limiting groove at the corresponding position of the second bevel gear 35, and the second bevel gear 35 rotates inside the limiting groove. The limiting groove positions the second bevel gear 35, so that the second bevel gear 35 rotates stably.

[0024] During operation, the limiting block 5 is installed inside the machine tool slide rail. Twisting the first threaded rod 28 to unscrew the threaded hole of the mounting block 21, the first threaded rod 28 pulls the slide rod 27, which in turn drives the locking block 25. The locking block 25 compresses the spring 26, which resets the locking block 25. The locking block 25 slides into the interior of the mounting block 21, disengaging from the connecting block 23. The connecting block 23 can then be removed from the slide groove of the mounting block 21. The clamping plate 24 can then be replaced by turning an Allen wrench. Rotating block 32 drives threaded cylinder 31, which in turn unscrews the second threaded rod 33. Simultaneously, threaded cylinder 31 drives first bevel gear 34, which in turn drives second bevel gear 35. The rotation of second bevel gear 35 causes the three first bevel gears 34 to rotate synchronously, which in turn causes the three threaded cylinders 31 to simultaneously unscrew the second threaded rod 33. The second threaded rod 33 drives connecting plate 22, which in turn drives mounting block 21. Mounting block 21 drives clamping plate 24 to clamp the seamless pipe.

[0025] By taking the above steps, the connecting block and clamp are replaced so that the shape and size of the clamp correspond to the shape and size of the seamless pipe. This solves the problem that if the size of the clamp does not correspond to the size and shape of the seamless steel pipe, the contact area between the clamp and the seamless steel pipe will be small, and the clamp may damage the seamless steel pipe.
