[0002] Steel pipe has a hollow cross-section and is a type of steel whose length is much greater than its diameter or circumference. It is widely used in transportation pipelines, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment and other fields. It is a material with a very wide range of applications.
[0003] In the prior art, the existing steel pipe processing fixture is provided with arc grooves on the two side clamps so that the upper clamping block and the lower clamping block can clamp the circular steel pipe. However, the diameter of the arc groove is fixed. However, if a steel pipe with a larger or smaller diameter is encountered, it may be necessary to replace other clamping blocks that are compatible with it in order to clamp more stably. When replacing the clamping blocks to adapt to steel pipes of different diameters, the staff disassembles the old clamping blocks, installs the new clamping blocks and performs debugging. These steps will increase the replacement time and reduce production efficiency. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figure 1-Figure 3 , the utility model provides a technical solution:
[0021] See Figure 1-Figure 3 As shown, a steel pipe processing fixture for steel pipe production and processing includes a mounting rod 1, the outer wall of the mounting rod 1 is provided with a thread, the outer wall of the mounting rod 1 is threadedly connected to a circular sleeve 2, the outer wall of the circular sleeve 2 is rotatably connected to a rotating rod 3, the rotating rod 3 is connected to a splint 4 at one end away from the circular sleeve 2, a connecting block 7 is fixedly installed at one end of the splint 4, a limiting block 8 is fixedly installed at the other end of the connecting block 7, a limiting frame 5 is fixedly installed on the outer wall of the mounting rod 1, the connecting block 7 is adapted to the through opening on the limiting frame 5, the area of the limiting block 8 is larger than the through opening on the limiting frame 5, a connecting rod 14 is fixedly installed on the arc block extending from the circular sleeve 2, and a handle 15 is fixedly installed at the other end of the connecting rod 14.
[0022] The staff puts the steel pipe on the outside of the splint 4, holds the handle 15, and rotates the handle 15 around the outer wall of the mounting rod 1. The width of the end of the splint 4 close to the limit frame 5 is greater than the width of the slot on the limit frame 5. The splint 4 will not pass through the through opening on the limit frame 5, so that the circular sleeve 2 moves on the mounting rod 1 toward the limit frame 5. The circular sleeve 2 will drive the bottom end of the rotating rod 3 to move in the direction of the limit frame 5. The top of the rotating rod 3 will lift the bottom end of the rotating rod 3 without shifting back and forth. The rotating rod 3 tends to a vertical state. The splint 4 and the first rubber layer 6 are against and fixed to the inner walls of steel pipes of different diameters, but are more suitable for fixing steel pipes of shorter lengths. At the same time, they can fix and clamp square and round steel pipes. It has stronger adaptability to clamping steel pipes of different shapes, and can clamp and fix steel pipes of different diameters and shapes without changing the clamp.
[0023] See Figure 2 A first rubber layer 6 is integrally formed on the splint 4 .
[0024] The first rubber layer 6 has good elasticity and friction, and can fit the surface of the steel pipe more closely, thereby improving the stability of clamping. This stability helps to reduce the movement and deviation of the steel pipe during processing and improve the processing accuracy.
[0025] See Figure 2 , the outer wall of the handle 15 is provided with a sponge.
[0026] The sponge surface usually has a certain degree of roughness or texture, which helps to increase the friction between the hand and the grip 15, preventing slipping due to sweating hands or vibration of the fixture during processing. This plays an important role in ensuring the safety and stability of the processing process.
[0027] See Figure 1-2 A fixing rod 11 is fixedly installed on one end of the mounting rod 1.
[0028] The fixing rod 11 can be connected with other movable devices to facilitate the displacement of the steel pipe through the fixing device, thereby facilitating further processing of the steel pipe.
[0029] See Figure 1-2 The outer wall of the circular sleeve 2 is sleeved with the first steel pipe 12 , and the clamping plate 4 is against the inner wall of the first steel pipe 12 .
[0030] The contact area between the splint 4 and the inner wall of the first steel pipe 12 is large and the contact is close, which helps to disperse the pressure of the clamp on the surface of the steel pipe and reduce the possibility of local indentation or damage. At the same time, if the splint 4 is designed with a rubber layer or other buffer material, it can further protect the surface of the steel pipe from damage.
[0031] See Figure 1-2 The materials of the mounting rod 1, the circular sleeve 2, the rotating rod 3 and the splint 4 are all steel.
[0032] Steel is a high-strength, high-hardness material capable of withstanding significant pressure and impact. During the steel pipe production process, clamps frequently clamp and rotate the pipes, requiring them to possess sufficient strength and durability. Steel clamps meet these requirements, ensuring they resist deformation or damage over extended periods of use.
[0033] See Figure 1-3 A clamping block 9 is fixedly mounted on the limit block 8 , a second rubber layer 10 is integrally formed on one side of the clamping block 9 , a second steel tube 13 is provided on one side of the mounting rod 1 , and the second rubber layer 10 abuts against the outer wall of the second steel tube 13 .
[0034] When the circular sleeve 2 is rotated, the rotating rod 3 and the clamping plate 4 drive the clamping block 9 and the second rubber layer 10 to fix and clamp steel pipes of different diameters. The second rubber layer 10 is installed on the upper and lower parts of the clamping block 9. The clamping block 9 can fix and clamp the inner wall of the second steel pipe 13, and can also fit the outer wall of the second steel pipe 13 to clamp it. It has better adaptability for clamping and fixing circular steel pipes of different diameters. At the same time, the clamping block 9 can fix and clamp both square and round steel pipes, and the efficiency of clamping the steel pipes is more efficient.
[0035] Working principle: The staff puts the steel pipe on the outside of the splint 4, holds the handle 15, and rotates the handle 15 around the outer wall of the mounting rod 1. The width of the end of the splint 4 close to the limit frame 5 is greater than the width of the slot on the limit frame 5. The splint 4 will not pass through the through opening on the limit frame 5, so that the circular sleeve 2 moves on the mounting rod 1 toward the limit frame 5. The circular sleeve 2 will drive the bottom end of the rotating rod 3 to move in the direction of the limit frame 5. The top of the rotating rod 3 will lift the bottom end of the rotating rod 3 without shifting back and forth. The rotating rod 3 tends to a vertical state. The splint 4 and the first rubber layer 6 are fixed against the inner walls of steel pipes of different diameters, but are more suitable for fixing shorter steel pipes. At the same time, square and round steel pipes can be fixed and clamped. It has stronger adaptability to clamping steel pipes of different shapes and can clamp and fix steel pipes of different diameters and shapes without changing the clamp.
[0036] When the circular sleeve 2 is rotated, the rotating rod 3 and the clamping plate 4 drive the clamping block 9 and the second rubber layer 10 to fix and clamp steel pipes of different diameters. The second rubber layer 10 is installed on the upper and lower parts of the clamping block 9. The clamping block 9 can fix and clamp the inner wall of the second steel pipe 13, and can also fit the outer wall of the second steel pipe 13 to clamp it. It has better adaptability for clamping and fixing circular steel pipes of different diameters. At the same time, the clamping block 9 can fix and clamp both square and round steel pipes, and the efficiency of clamping the steel pipes is more efficient.
