Description

Technical Field

[0001] The utility model provides a multi-directional adjustment auxiliary device, belongs to the technical field of metal pipe welding equipment, and particularly relates to a multi-directional adjustment auxiliary device used for metal pipe welding. Background Art

[0002] Metal pipe welding refers to the technology of connecting two or more metal pipes together through processes such as heating, melting and cooling. This process can use a variety of welding methods, such as arc welding, argon arc welding, laser welding, etc., to achieve a stable connection of metal pipes. During the welding process, the metal material in the welding area melts at high temperature and forms a strong connection structure after cooling. Welding metal pipes can form a high-strength connection to ensure that the pipeline system can withstand high pressure and mechanical stress. This is especially important in high-pressure pipeline systems such as oil pipelines and natural gas pipelines. Metal pipe welding technology is widely used in construction, shipbuilding, automobiles, aerospace, energy and other fields, and is an indispensable manufacturing and maintenance process in these industries.

[0003] Existing metal pipe welding is mostly done manually. However, the shape of the metal pipe is difficult to fix and it is easy to roll, causing the welding position to shift and resulting in welding failure. At the same time, when directly welding the metal pipe manually, there are certain safety hazards in manually fixing the position of the pipe body. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, the embodiments of the present application provide a multi-directional adjustment auxiliary device for metal pipe welding, thereby solving the problems of weak fixation of existing metal pipe welding, inconvenience in welding and potential safety hazards in manual fixation welding.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a multi-directional adjustment auxiliary device for metal pipe welding, comprising a base, wherein the upper part of the base is movably connected with a mutually perpendicular fixed structure, the fixed structure comprises a pair of correspondingly distributed clamping rings placed above the base, a movable clamping plate is provided inside the clamping ring, and a sliding plate placed inside the base is connected to the end of the clamping ring close to the base through a T-shaped limit rod.

[0006] Preferably: the base is provided with sliding grooves which are perpendicular to each other and correspond to the sliding plate, and a connecting rod which is fixedly connected to the limiting rod is provided above the sliding plate.

[0007] Preferably, a connector inserted by the limiting rod is fixedly connected below the clamping ring close to the base, and connecting plates are fixedly connected to both sides of the opening of the clamping ring, and a bolt structure penetrating the connecting plate is provided inside the connecting plate.

[0008] Preferably, a groove corresponding to the clamping plate is provided inside the clamping ring, and a friction plate penetrating a plate body on one side of the groove is fixedly connected to the inner side of the clamping plate.

[0009] Preferably, the length of the clamping ring is greater than the length of the clamping plate.

[0010] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0011] The utility model realizes clamping of the pipe body in the longitudinal direction and the transverse direction respectively by arranging a vertically distributed fixed structure placed above the base, and drives the clamping ring to adjust its position by means of a sliding plate, while a limit rod is used to realize the rotation of the clamping ring, thereby being able to adapt to pipe bodies with different bending degrees and realizing better clamping. During welding, the clamping plate can drive the pipe body to rotate in the clamped state, thereby facilitating the annular welding of the pipe body port and making the welding more stable.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific implementation methods and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] like Figure 1 and Figure 2 As shown, a multi-directional adjustment auxiliary device for welding metal pipes includes a base 1, a fixed structure 2 located above the base 1 and movably connected to each other perpendicularly, a sliding groove 12 located on the base 1 and perpendicular to each other and corresponding to a sliding plate 11, a connecting rod 13 fixedly connected to a limiting rod 23 is provided above the sliding plate 11, the fixed structure 2 includes a pair of correspondingly distributed clamping rings 21 located above the base 1, a movable clamping plate 22 is provided inside the clamping ring 21, and the end of the clamping ring 21 close to the base 1 is connected to the sliding plate 11 located inside the base 1 through a T-shaped limiting rod 23.

[0026] In this embodiment, a vertically distributed fixed structure 2 is arranged above the base 1 to clamp the tube body longitudinally and transversely respectively, and the sliding plate 11 is used to drive the clamping ring 21 to adjust its own position. At the same time, the limit rod 23 is used to realize the rotation of the clamping ring 21, so as to adapt to tubes with different bending degrees and achieve better clamping. During welding, the clamping plate 22 can drive the tube body to rotate in the clamped state, thereby facilitating the annular welding of the tube body port and making the welding more stable.

[0027] like Figure 3 and Figure 4As shown, a connector 14 inserted by a limiting rod 23 is fixedly connected to the lower part of the clamping ring 21 near the base 1, and connecting plates 24 are fixedly connected to both sides of the opening of the clamping ring 21. A bolt structure 25 is provided through the connecting plate 24, and a groove 26 corresponding to the clamping plate 22 is provided inside the clamping ring 21. A friction plate 27 that passes through a plate body on one side of the groove 26 is fixedly connected to the inner side of the clamping plate 22. The length of the clamping ring 21 is greater than the length of the clamping plate 22.

[0028] In this embodiment, bolt structures 25 are fixedly connected on both sides of the connecting plate 24. This design enables the connecting plate to be firmly fixed on the clamping ring. At the same time, through the adjustment of the bolt structure, the position of the connecting plate and the tension of the clamping ring can be flexibly adjusted to adapt to different pipe sizes and shapes. A groove corresponding to the clamping plate is provided inside the clamping ring. This design can ensure the accurate position of the clamping plate inside the clamping ring, and the inner friction plate provides additional stable support to prevent unnecessary sliding of the clamping plate during operation, thereby ensuring the stability and accuracy of the welding process; the length of the clamping ring is greater than the length of the clamping plate. When the pipe body rotates and drives the clamping plate 22 to rotate together, the clamping plate 22 on one side enters the other clamping ring 21. At this time, the support ring 21 is limited by the curvature of the clamping plate 22, and the connection is more stable. The connecting ring 21 is inseparable. Only when the clamping plates 22 are respectively in different clamping rings 21, the clamping ring 21 can be separated.

[0029] In summary, these structural designs help to improve the operational performance and stability of the auxiliary devices, ensure accurate positioning and secure clamping of pipes during welding, and thus improve welding quality and efficiency.

[0030] When using:

[0031] 1. Preparation:

[0032] Determine the size and shape of the metal pipe fittings to be welded.

[0033] Check the various components of the auxiliary device, including the base 1, the fixing structure 2, the sliding plate 11, the limiting rod 23, the clamping ring 21, the connecting plate 14, the bolt structure 25, the clamping plate 22, etc., to ensure that all parts are intact and in normal working condition.

[0034] 2. Fixed base:

[0035] Fix the base 1 on a stable workbench to ensure that the base is stable and does not shake.

[0036] 3. Adjust the position of the sliding plate:

[0037] The specific position of the sliding plate 11 is adjusted through the sliding groove 12 according to the length of the pipe and the welding position requirements.

[0038] Ensure that the connecting rod 13 connecting the sliding plate 11 and the limiting rod 23 is firmly fixed.

[0039] 4. Clamping pipe fittings:

[0040] The pipe is placed between the clamping rings 21 , and the clamping rings 21 are adjusted in multiple directions in longitudinal and transverse directions by adjusting the limit rods 23 and the sliding plates 11 , so as to ensure that the pipe is clamped in a suitable position.

[0041] The position of the clamping plate 22 is adjusted so that it is accurately inserted into the groove 26 inside the clamping ring 21 .

[0042] By adjusting the bolt structure 25 on the connecting plate 24, the tension of the clamping ring 21 and the clamping plate 22 is adjusted according to the size and shape of the pipe fitting to ensure that the pipe fitting is stably fixed.

[0043] 5. Rotation adjustment:

[0044] When the pipe fitting needs to be annularly welded, the clamping plate 22 can be rotated to drive the pipe fitting to rotate together.

[0045] 6. Welding:

[0046] After confirming that the pipe is firmly clamped and in the correct position, proceed with the welding operation.

[0047] During the welding process, the position of the movable clamping plate 22 can be adjusted at any time to meet the welding requirements and ensure the smooth progress of the welding process.

[0048] 7. Post-welding treatment:

[0049] After welding is completed, the bolt structure 25 is loosened and the upper clamping ring 21 is removed.

[0050] Take out the welded pipe fittings and check the welding quality and stability.

[0051] 8. Finishing work:

[0052] Clean auxiliary devices and workbenches to ensure that the equipment is intact the next time you use it.

[0053] Check whether all parts of the device are damaged and perform maintenance and care in a timely manner.

[0054] Through the above steps, the metal pipe can be stably fixed and adjusted in multiple directions during the welding process, thereby improving the welding accuracy and efficiency.
