Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting clamping devices, in particular to a polygonal pipe fitting clamping device. Background Art

[0002] Pipe fittings are key elements for connecting, steering, supporting, and controlling the flow of liquids or gases. They are used to connect pipes, pipelines, and equipment, as well as to change the direction and angle of pipes. Different types of pipe fittings have different functions, such as elbows, tees, flanges, etc. Through different combinations and installation methods, pipe fittings can meet various engineering and application requirements. Then in the process of use, it is inevitable to avoid cutting, fixing, welding and other processes, so pipe fitting clamping devices are needed to assist the operation. Pipe fitting clamping devices are tools and equipment used to fix and support pipe fittings to ensure the stability and safety of pipe fittings during operation. Existing pipe fitting clamping devices include U-shaped clamps: composed of a pair of U-shaped clamps, but can only fix some pipe fittings with smaller diameters. C-type clamps: C-shaped, can fix larger pipe fittings, but are not suitable for some thinner and easily deformed pipe fittings. Bench vise clamp: uses threaded screws to lock and clamp. The clamps described above have a small application range and are relatively simple. They cannot be adjusted according to different types of clamped pipes. They all use threaded screw mechanisms to achieve the purpose of locking, which can easily damage some thinner pipes. During use, once tightened, if you want to reposition the pipe, you can only loosen it and move it, which is cumbersome, time-consuming and labor-intensive. For some places where feeding is required while clamping, this type of ordinary clamping device cannot meet the needs.

[0047] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0048] Embodiment 1:

[0049] refer to Figure 1-2 As shown, a polygonal pipe clamping device includes a base 1 and a gantry 2. A plurality of V-shaped clamping mechanisms are installed on the base 1.

The tripod 3 is installed on the base 1. A pin 301 is rotatably installed on the tripod 3. The bottom ends of the first force plate 4 and the second force plate 5 are rotatably connected to the pin 301 respectively. A V shape is formed between the first force plate 4 and the second force plate 5.

[0050] The first angle adjustment mechanism 6 includes a first positioning plate 601, a first positioning nut 602, a first screw rod 603, and a first adjusting member 604. The first positioning plate 601 is mounted on the base 1 below the first force plate 4. The first adjusting member 604 is fixedly connected to the lower portion of the first force plate 4. The first positioning nut 602 is externally rotatably connected to the first positioning plate 601. One end of the first screw rod 603 is internally threadedly connected to the first positioning nut 602. The other end of the first screw rod 603 is movably connected to the first adjusting member 604.

[0051] The second angle adjustment mechanism 7 includes a second positioning plate 701, a second positioning nut 702, a second screw rod 703, and a second adjusting member 704. The second positioning plate 701 is mounted on the base 1 below the second force plate 4. The second adjusting member 704 is fixedly connected to the lower portion of the second force plate 4. The outer portion of the second positioning nut 702 is rotatably connected to the second positioning plate 701. One end of the second screw rod 703 is threadedly connected to the inner portion of the second positioning nut 702.

The locking mechanism 10 is connected to the rotating shaft 801 .

[0053] The first and second force plates 4 and 5 are roughly adjusted in the inclination angle according to the shape of the pipe fitting. First, the first positioning nut 602 is rotated to rotate relative to the first positioning plate 601. Since the first screw 603 is threadedly connected to the first positioning nut 602, the first screw 603 can change its position relative to the first positioning plate 601, and the first screw 603 can pull or push the position of the first adjusting member 604, thereby driving the first force plate 4 to approach the first positioning plate 601 or move away from the first positioning plate 601, thereby changing its inclination angle. Similarly, the second positioning nut 702 is rotated to rotate relative to the second positioning plate 701. Since the second screw 703 is threadedly connected to the second positioning nut 702, the second The screw rod 703 can change its position relative to the second positioning plate 701, and the second screw rod 703 can pull or push the position of the second adjusting member 704, thereby driving the second force plate 4 to approach the second positioning plate 701 or move away from the second positioning plate 701, and the first force plate 4 and the second force plate 5 rotate around the pin 301 to change their inclination angles. The structure of the pipe fitting is adapted by adjusting the angles of the first force plate 4 and the second force plate 5, and the pipe fitting is placed between the first force plate 4 and the second force plate 5 of the V-shaped clamping mechanism, and then fine-tuned. According to the above method, the inclination angles and relative positions of the first force plate 4 and the second force plate 5 are adjusted until the angles are close to the angles of the two lower surfaces required to be clamped by the pipe fitting. Then, the locking mechanism 10 is opened to release the rotating shaft 801, and the connecting rod 8 is lowered until the clamping wheel 9 on the connecting rod 8 clamps the upper part of the pipe fitting. After the position is positioned, the rotating shaft 801 of the connecting rod 8 is locked by the locking mechanism 10, and the purpose of clamping the pipe fitting is achieved. The locking mechanism 10 can be any mechanism that can position the rotating shaft 801 to prevent it from rotating, and those skilled in the art can select existing technologies by themselves, such as using a buckle structure to lock the rotating shaft 801 and the gantry 2.

[0055] The first groove 6011 of the first positioning plate 601 is used to place the first positioning nut 602. The first recessed portion 6021 of the first positioning plate 601 is inserted into the first groove 6011 to be rotatably connected thereto. The first positioning nut 602 is slidably moved in the first groove 6011 to change its position. The application range is wide and the adjustment is convenient.

[0056] Similarly, reference Figure 4 As shown, a second groove body 7011 is formed on the second positioning plate 701 , a second recessed portion 7021 is formed on the outside of the second positioning nut 702 , and the second recessed portion 7021 is movably disposed in the second groove body 7011 .

[0057] The second groove body 7011 of the second positioning plate 701 is used to place the second positioning nut 702. The second recessed portion 7021 is inserted into the second groove body 7011 to be rotatably connected thereto, and the second positioning nut 702 is slid in the second groove body 7011 to change its position. It has a wide range of applications and is easy to adjust.

[0060] By hingedly connecting the first ball head 6031 with the first ball head connecting rod 6041 and the second ball head 7031 with the second ball head connecting rod 7041, not only the position change of the first screw rod 603 and the second screw rod 703 is applicable, but also the connection is more stable, so that the first force plate 4 and the second force plate 5 can provide more stable positioning support for the pipe fitting.

[0064] When in use, after the angles of the first force plate 4 and the second force plate 5 are adjusted, the positions of the first V-shaped supporting mechanism 11 and the second V-shaped supporting mechanism 12 are adjusted according to the positions of the bottom of the pipe fitting. The specific process is as follows: first, the first sliding block 403 is moved to slide on the first guide shaft 402 of the first through hole 401 to change the height position. At the same time, the first adjusting rod 1101 also slides in the first adjusting through hole 4021, thereby driving the first fixing frame 1102 to move, thereby driving the first V-shaped block 1103 and the first roller 1104 to move to a suitable position, and then the first rollers 1104 at both ends of the first V-shaped block 1103 are used to support the pipe fitting to play a positioning role for the pipe fitting. After the position is determined, the first adjusting rod 1101 is rotated to make it rotate with the first sliding block 403 threadably, and then the first fixing frame 1102 is pulled to move close to the first force plate 4, so that the first fixing frame 1102 and the first force plate 4 are locked, thereby fixing the position of the first sliding block 403. Similarly, the second sliding block 503 is moved to the second through hole 4021.
