Description

Technical Field

[0001] This utility model relates to the field of pipe welding, and in particular to a quick-connect pipe welding clamp. Background Technology

[0002] Pipe welding fixtures are essential tools for pipe welding operations. They can precisely position the pipe, ensuring the accuracy and consistency of the weld, making the weld joint meet quality standards, and effectively avoiding welding defects caused by pipe position deviations. They have a certain degree of versatility and adjustability, and can be adapted to pipes of different diameters and materials. By adjusting their own structural parameters, they can meet the needs of various pipe welding scenarios. They are mainly used in industries such as pharmaceutical pipelines, food, bioengineering, electronics, instrumentation, and pipeline installation, playing a key role in improving welding efficiency and quality.

[0003] Quick-connect pipe welding fixtures are highly efficient auxiliary equipment for pipe welding. Utilizing a specially designed quick-connect structure, operators can quickly insert the pipe into the positioning and clamping parts of the fixture. Through simple operations (such as rotating the handle or pushing the slider), the clamping device inside the fixture is activated quickly, thereby firmly fixing the pipe in place. This ensures that the pipe maintains a precise position and stable state during the welding process, preventing displacement and shaking, and providing a reliable guarantee for high-quality welding. It greatly improves the efficiency and accuracy of pipe welding and is suitable for various pipe welding operation scenarios.

[0004] In existing technologies, some pipe welding clamps rely on relatively simple mechanical clamping or bolt fastening methods for reinforcement. After long-term use, due to wear and loosening of components and the influence of external environmental factors (such as vibration and temperature changes), their reinforcement performance gradually declines. This leads to inaccurate positioning and displacement of the pipe during welding, which seriously affects the welding quality and produces defects such as uneven welds and incomplete penetration. It also reduces work efficiency, increases maintenance costs and safety risks, such as pipe leaks. Therefore, a quick-connect pipe welding clamp is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quick-connect pipe welding fixture, which aims to improve the problems of inaccurate positioning and displacement of pipes during welding in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quick-connect pipe welding clamp includes a housing. Two rotating rings are rotatably connected to the rear left side of the housing. The rotating rings have a fixing groove inside. A connecting block is fixedly connected to the front side of the housing. A connecting plate is fixedly connected to the front side of the connecting block. A rotating plate is rotatably connected to the outside of the connecting plate. A fixing column is fixedly connected inside the rotating plate. A connecting rod is rotatably connected to the outside of the fixing column. A connecting plate is fixedly connected to the front side of the connecting rod. A fixing plate is fixedly connected to the left side of the connecting plate. A fixing block is fixedly connected to the left side of the fixing plate. An adjusting component for adjusting the clamping force is provided inside the rotating rings.

[0008] As a further description of the above technical solution:

[0009] The adjustment assembly includes a placement groove, with multiple springs fixedly connected in a ring on the inner wall of the placement groove, and an adjustment ring fixedly connected to the right side of the multiple springs. The rotating ring has a rotating groove inside, and an adjustment knob is rotatably connected inside the rotating groove. A cam is fixedly connected to the bottom of the adjustment knob.

[0010] As a further description of the above technical solution:

[0011] The outer surfaces of the fixing plate and the fixing block are in contact with the inner wall of the fixing groove, respectively. The fixing plate and the fixing block rotate around the fixing column through the connecting plate and the connecting rod.

[0012] As a further description of the above technical solution:

[0013] The rotating ring is opened by rotating the rotating plate to pull out the fixing plate and the fixing block; the rotating ring is placed inside the fixing block by rotating the rotating plate and the fixing block to fix it.

[0014] As a further description of the above technical solution:

[0015] A fixed ring is fixedly connected inside the housing, and a carrier ring is rotatably connected inside the fixed ring;

[0016] As a further description of the above technical solution:

[0017] The convex surface of the cam contacts the outside of the adjusting ring, and the cam rotates inside the rotating groove by rotating the adjusting knob;

[0018] As a further description of the above technical solution:

[0019] The clamping force is adjusted by squeezing the adjusting ring through the rotating cam, and the adjusting ring is automatically reset by the spring.

[0020] As a further description of the above technical solution:

[0021] A handle is fixedly connected to the right side of the housing, and a power port is provided inside the handle on the right side.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the fixing plate and fixing block are first placed in the fixing groove, and then the rotating plate is rotated in the opposite direction. The fixing column causes the connecting rod and connecting plate to generate a tension force in opposite directions on the fixing plate and fixing block, thereby achieving a stable fixation of the pipeline during welding, effectively preventing its displacement and shaking. The operation is simple and efficient, enhancing the practicality and reliability of the fixture. It is suitable for various pipeline welding scenarios and reduces welding defects and safety hazards caused by insecure fixing.

[0024] 2. In this utility model, rotating the adjustment knob drives the cam to rotate in the rotating groove. As the cam rotates, it squeezes the adjustment ring. Under the elastic action of the spring, the adjustment ring generates different degrees of pressure on the clamp, thereby realizing the adjustment of the clamping force. This allows the clamp to flexibly adapt to pipes of different diameters and materials, and accurately control the clamping force, ensuring the stability of the pipe during the welding process, avoiding loosening or excessive compression and deformation, and improving the welding quality.

[0031] 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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a quick-connect pipe welding clamp, including a housing 1. The housing 1 provides installation space and protection for internal components. Two rotating rings 2 are rotatably connected to the left rear of the housing 1. The rotating rings 2 can be rotated to change the size of the clamp and place the pipe. The rotating rings 2 have a fixing groove 3 inside. The fixing groove 3 cooperates with the fixing plate 10 and the fixing block 11 to fix the rotating ring 2. A connecting block 4 is fixedly connected to the front of the housing 1. The connecting block 4 connects the housing 1 and the connecting plate 5. The connecting plate 5 is fixedly connected to the front of the connecting block 4. The connecting plate 5 connects the connecting block 4 and the rotating plate 6. The rotating plate 6 is rotatably connected to the outside of the connecting plate 5. The rotating plate 6 is fixed when rotated to the right and can be removed when rotated to the left.

[0033] The rotating plate 6 is internally fixedly connected to a fixed column 7, which serves as a fixed support for the rotating plate 6 and the fixed column 7. The fixed column 7 is externally rotatably connected to a connecting rod 8, which connects the rotating plate 6 and the connecting plate 9. The front side of the connecting rod 8 is fixedly connected to the connecting plate 9, which connects the connecting rod 8 and the fixed plate 10. The left side of the connecting plate 9 is fixedly connected to the fixed plate 10, which cooperates with the fixed block 11 to complete the limiting. The left side of the fixed plate 10 is fixedly connected to the fixed block 11, which is wider than the fixed plate 10, so as to better limit and fix it and prevent accidental fall-off. The rotating ring 2 is internally provided with an adjustment component for adjusting the clamping force.

[0034] Reference Figure 2 and Figure 4The adjustment assembly includes a placement groove 12, which is used to place the clamp and provide installation space for the internal adjustment assembly. Multiple springs 13 are fixedly connected in a ring on the inner wall of the placement groove 12. The springs 13 provide elasticity to the adjustment ring 14. The adjustment ring 14 is fixedly connected to the right side of the multiple springs 13. The adjustment ring 14 contacts the clamp to facilitate adjustment of the tension. The rotating ring 2 has a rotating groove 15 inside, which provides rotation space for the adjustment knob 16 and the cam 17. The adjustment knob 16 is rotatably connected inside the rotating groove 15. The adjustment knob 16 is used to drive the cam 17 to rotate. The cam 17 is fixedly connected to the bottom of the adjustment knob 16. When the cam 17 rotates, the thicker side fits against the outside of the adjustment ring 14 and is pressed.

[0035] Reference Figures 2 to 4 The outer surfaces of the fixing plate 10 and the fixing block 11 are in contact with the inner wall of the fixing groove 3. After the clamp and pipe are placed, the fixing plate 10 and the fixing block 11 are placed inside the fixing groove 3 to fix the rotating ring 2. The fixing plate 10 and the fixing block 11 rotate around the fixing column 7 through the connecting plate 9 and the connecting rod 8. The connecting plate 9, the fixing plate 10 and the fixing block 11 connected to it can rotate outside the fixing column 7 through the connecting rod 8, thereby releasing the limitation on the rotating ring 2. The rotating ring 2 is pulled out by the rotation of the rotating plate 6 and the fixing plate 10 and the fixing block 11 are opened. When the rotating plate 6 is rotated, the tension force in the opposite direction of the connecting rod 8 disappears, and the fixing plate 10 and the fixing block 11 can be removed to release the limitation on the rotating ring 2.

[0036] The rotating ring 2 is placed inside the fixed block 11 by the fixed plate 10 and the fixed block 11, and then the rotating plate 6 is rotated to fix it. When it is necessary to fix the rotating ring 2, the fixed plate 10 and the fixed block 11 are first placed inside the fixed groove 3. At this time, the rotating plate 6 is rotated to create a tension force in the opposite direction, so that it cannot be separated from the fixed groove 3, thus completing the limit fixation. The housing 1 is fixedly connected to the inside of the fixed ring. The fixed ring provides rotation space for the internal carrier ring 18. The carrier ring 18 is rotatably connected inside the fixed ring. The carrier ring 18 is driven to rotate by the internal gear, which in turn drives the welding rod to rotate, thus completing the welding of the pipe 360. The convex surface of the cam 17 is in contact with the outside of the adjusting ring 14. When the cam 17 rotates, it squeezes the adjusting ring 14, which can adjust the tension.

[0037] The cam 17 rotates inside the rotating groove 15 by rotating the adjusting knob 16. The cam 17 rotates by adjusting the knob 16, thereby adjusting the squeezing force on the adjusting ring 14. The clamping force is adjusted by squeezing the adjusting ring 14 by rotating the cam 17. When the cam 17 rotates, its convex surface squeezes the adjusting ring 14, thereby squeezing the clamp and adjusting the clamping force. The adjusting ring 14 is automatically reset by the spring 13. When the rear side of the cam 17 rotates, the adjusting ring 14 is reset by the elastic action of the spring 13. A handle 19 is fixedly connected to the right side of the housing 1. The handle 19 facilitates the operation of the welding device. A power port 20 is opened on the right side of the handle 19, and the power cord is powered through the power port 20.

[0038] Working principle: When the pipe is placed and the rotating ring 2 needs to be fixed, rotate the rotating ring 2 to a suitable position, first place the fixing plate 10 and fixing block 11 in the fixing groove 3, then rotate the rotating plate 6 in the opposite direction. Through the fixing column 7, the connecting rod 8 and connecting plate 9 generate opposite tension forces on the fixing plate 10 and fixing block 11, thereby fixing the rotating ring 2 and making the pipe stably fixed in the fixture. This ensures that the pipe will not be displaced during the welding process and provides a stable foundation for subsequent welding.

[0039] When it is necessary to adjust the clamping force of the clamp on the pipe, turn the adjustment knob 16 to drive the cam 17 to rotate in the rotating groove 15. As the cam 17 rotates, it squeezes the adjusting ring 14. Under the elastic action of the spring 13, the adjusting ring 14 generates different degrees of pressure on the clamp, thereby realizing the adjustment of the clamping force. When the thicker side of the cam 17 squeezes the adjusting ring 14, the clamping force increases. When the cam 17 rotates and the thinner side contacts the adjusting ring 14, the adjusting ring 14 automatically resets under the action of the spring 13, and the clamping force decreases. In this way, the clamping degree of the clamp on the pipe can be flexibly adjusted to meet the pipe fixing requirements of different pipe diameters and welding requirements.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
