Description

Technical Field

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

[0002] Pipe cutting is a process that requires precise operation and strict adherence to safety regulations. Pipe cutting methods include mechanical cutting, flame cutting, plasma cutting, and high-pressure water cutting. After cutting, slag and oxide scale should be removed by machining or grinding. When cutting the pipe, the two ends that need to be cut should be clamped to ensure stability during the cutting process.

[0003] However, most of the clamps currently used for clamping pipes have a fixed diameter, making it inconvenient to clamp pipes with smaller diameters. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a clamping device for pipe cutting, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a clamping device for pipe cutting, including a clamping mechanism, wherein two clamping cover plates are provided inside the clamping mechanism, and a diameter adjustment mechanism is installed on each of the two clamping cover plates. The diameter adjustment mechanism includes a movable connecting rod, a clamping connecting rod, and a second fastening screw. An installation pad is provided between the second fastening screw and the movable connecting rod. A rotating sleeve is installed on the upper surface of the installation pad. A rotating bearing is installed on the outer side of the second fastening screw inside the rotating sleeve. A clamping ball is installed at the lower end of the clamping connecting rod.

[0006] As a further improvement of this utility model: an adjustment frame is installed on the upper end of the clamping cover plate, and a second threaded through hole is provided inside the adjustment frame on the inner side of the second fastening screw.

[0007] As a further improvement of this utility model: connecting ear plates are installed at the ends of both clamping cover plates, and a first threaded through hole is provided on the connecting ear plate, and a first fastening screw is provided inside the first threaded through hole.

[0008] As a further embodiment of this utility model: the clamping link and the movable link are movably connected by a rotating shaft, and the movable link and the mounting pad are movably connected by a rotating shaft.

[0009] As a further improvement of this utility model: the second fastening screw is movably connected to the rotating sleeve through the rotating bearing.

[0010] As a further embodiment of this utility model: the second fastening screw is movably connected to the second threaded hole, and the adjusting frame is fixedly connected to the clamping cover plate.

[0011] As a further improvement of this utility model, the inside of the clamping cover plate is provided with a movable through hole located on the outside of the movable connecting rod.

[0012] As a further improvement of this utility model, the first fastening screw is engaged and movably connected with the first threaded hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When torque is applied to the fastening screw, the mounting plate is pushed downwards, which moves the movable connecting rod and clamping connecting rod on the outside of the mounting plate. This controls the clamping connecting rod to move closer to the center of the clamping mechanism inside the clamping cover plate, thus clamping the pipe inside. Attached Figure Description

[0021] 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.

[0022] like Figure 1-5 As shown, this embodiment provides a clamping device for pipe cutting, including a clamping mechanism 1. Two clamping cover plates 2 are disposed inside the clamping mechanism 1, and a diameter adjustment mechanism 6 is installed on each of the two clamping cover plates 2. The diameter adjustment mechanism 6 includes a movable connecting rod 601, a clamping connecting rod 602, and a second fastening screw 605. A movable through hole is provided inside the clamping cover plate 2 on the outer side of the movable connecting rod 601. The clamping connecting rod 602 is movably connected to the movable connecting rod 601 via a rotating shaft. The second fastening screw... A mounting plate 604 is provided between rod 605 and movable connecting rod 601. Movable connecting rod 601 and mounting plate 604 are movably connected by a rotating shaft. A rotating sleeve 607 is installed on the upper surface of mounting plate 604. A rotating bearing 606 is installed on the outer side of the second fastening screw 605 inside the rotating sleeve 607. The second fastening screw 605 is movably connected to the rotating sleeve 607 through the rotating bearing 606. A clamping ball 603 is installed at the lower end of clamping connecting rod 602.

[0023] like Figure 2-3 As shown, in this embodiment, an adjusting frame 4 is installed on the upper end of the clamping cover plate 2. The adjusting frame 4 is fixedly connected to the clamping cover plate 2. The interior of the adjusting frame 4 is provided with a second threaded through hole 401 located inside the second fastening screw 605. The second fastening screw 605 is engaged and movably connected with the second threaded through hole 401. Both ends of the clamping cover plates 2 are provided with connecting ear plates 3. A first threaded through hole 301 is provided on the connecting ear plate 3. A first fastening screw 5 is provided inside the first threaded through hole 301. The first fastening screw 5 is engaged and movably connected with the first threaded through hole 301.

[0024] The working principle of this utility model is as follows: During use, two clamping cover plates 2 are placed on the outside of the pipe to be processed. The first fastening screw 5 is connected as a whole to the first threaded through hole 301 inside the connecting ear plate 3. By applying torque to the connecting ear plate 3, the connecting ear plate 3 is driven to engage with the first threaded through hole 301, controlling the two clamping cover plates 2 to move towards each other, thereby clamping the pipe. When the outer diameter of the pipe to be processed is less than the inner diameter of the clamping mechanism 1... When the second fastening screw 605 is subjected to torque, the rotating bearing 606 at the end of the second fastening screw 605 will rotate inside the rotating sleeve 607 at the upper end of the mounting plate 604. The second fastening screw 605 pushes the mounting plate 604 downward, which moves the movable connecting rod 601 and the clamping connecting rod 602 on the outside of the mounting plate 604. This controls the clamping connecting rod 602 to move closer to the center of the clamping mechanism 1 inside the clamping cover plate 2, thereby clamping the internal pipe.
