Abstract
Description
Technical Field

[0002] In modern industrial production, pipeline welding is an extremely important process link, which is widely used in many fields such as petroleum, chemical industry, electric power, construction, etc. With the continuous development of industrial technology, the requirements for pipeline welding quality and efficiency are increasing day by day.
[0003] Traditional pipe welding methods have many limitations. On the one hand, there is a lack of effective adjustment methods when welding pipes of different specifications and positions. The fixed structure of many welding equipment is relatively simple, which is difficult to adapt to the changes in pipe diameter and the needs of pipe docking in different spatial positions. It often takes a lot of time and manpower to position and adjust the pipes, which not only reduces the welding efficiency, but also easily leads to welding quality problems due to inaccurate positioning, such as uneven welds, pores or cracks.
[0004] On the other hand, some existing welding equipment has a low degree of automation. During the welding process, it is necessary to manually adjust the welding parameters and welding positions frequently, which not only increases the labor intensity of the operators, but also makes it difficult to ensure the quality consistency of each welding due to the influence of human factors. In addition, for some pipes that require circumferential welding, the traditional manual rotation or fixed support method is difficult to achieve stable and precise rotation, which further affects the welding quality.

Example
[0021] Refer to the attached Figures 1 to 8 An adjustable pipeline welding device includes a workbench 1, a welding mechanism 2 is arranged on the workbench 1, a position adjustment mechanism 3 is arranged on the left and right sides of the welding mechanism 2, a rotating mechanism 4 is arranged on the output end of one position adjustment mechanism 3, and a supporting assembly 5 is arranged on the output end of the other position adjustment mechanism 3. The rotating mechanism 4 is used to fix and rotate a pipeline 6 to be welded, and the supporting assembly 5 is used to support or fix another pipeline 6 to be welded.
[0022] The welding mechanism 2 comprises a mechanical arm 21 fixed on the workbench 1 , and a welding gun 22 is arranged on the output end of the mechanical arm 21 .
[0023] The position adjustment mechanism 3 includes an X-axis linear module 31 arranged on the workbench 1, and X-axis guide rail assemblies 32 are arranged on both sides of the X-axis linear module 31. An X-axis moving block 33 is arranged on the output end of the X-axis linear module 31, and the lower end of the X-axis moving block 33 is also connected to the X-axis guide rail assembly 32. The upper end of the X-axis moving block 33 is provided with a Y-axis linear module 34 and a Y-axis guide rail assembly 35 arranged on both sides of the Y-axis linear module 34, and a Y-axis moving block 36 is arranged on the output end of the Y-axis linear module 34, and the lower end of the Y-axis moving block 36 is connected to the Y-axis guide rail assembly 35.
[0024] The rotating mechanism 4 includes a mounting frame 41 fixed on a Y-axis moving block 36 , on which a connecting cylinder 43 is rotatably mounted. One end of the connecting cylinder 43 is connected to a three-jaw chuck 42 , and the other end is connected to a motor 45 via a gear set 44 .
[0025] The support assembly 5 includes a clamping mechanism 51 and roller frames 52 arranged at the front and rear sides of the clamping mechanism 51. The clamping mechanism 51 includes a mounting seat 511. Two clamping cylinders 512 are symmetrically arranged on the mounting seat 511. A clamping block 513 is arranged at the output end of the clamping cylinder 512. Supports 514 are arranged on the left and right sides of the mounting seat 511. A guide shaft 515 is arranged on the support 514. The guide shaft 515 is arranged along the X-axis direction. A guide block 516 is arranged on the clamping block 513. The guide block 516 is slidably sleeved on the guide shaft 515.
[0026] Working principle: Prepare two pipes 6 to be welded. Place one pipe 6 on the three-jaw chuck 42 of the rotating mechanism 4, and fix the pipe by the clamping action of the three-jaw chuck 42. Place the other pipe on the clamping mechanism 51 and the roller frame 52 of the supporting assembly 5. According to the diameter and position requirements of the pipe, the clamping block 513 is driven to move by the extension and contraction of the clamping cylinder 512 to support and fix the pipe. At the same time, the guide block 516 slides on the guide shaft 515 to ensure the stability and accuracy of the movement of the clamping block 513.
[0027] According to the relative position of the two pipes 6 to be welded and the welding requirements, the position adjustment mechanism 3 is started. For the position adjustment mechanism 3 equipped with the rotating mechanism 4, the X-axis linear module 31 is controlled to move the X-axis moving block 33 to a suitable position along the X-axis direction under the guidance of the X-axis guide assembly 32; then the Y-axis linear module 34 is started to drive the Y-axis moving block 36 to move along the Y-axis direction under the guidance of the Y-axis guide assembly 35, so as to accurately adjust the spatial position of the rotating mechanism 4. Similarly, for the position adjustment mechanism 3 equipped with the support assembly 5, the position adjustment in the X-axis and Y-axis directions is also performed in a similar manner to accurately align the ports of the two pipes and prepare for welding.
[0028] After the positions of the two pipes are adjusted, the welding mechanism 2 is started. The mechanical arm 21 drives the welding gun 22 to move to the welding starting position according to the preset welding path and parameters. The welding gun 22 sprays high-temperature flames or arcs to weld the butt joints of the two pipes to make the welds uniform and firm. After welding a part, the clamping mechanism 51 releases the pipe 6, and then the motor 45 is started, driving the connecting cylinder 43 and the three-jaw chuck 42 to rotate through the gear set 44, thereby driving the fixed pipe 6 to rotate. During the rotation of the pipe 6, the roller frame 52 can assist in supporting the clamped pipe to keep it stable during the welding process.
[0029] When the welding is completed for one circle or reaches the preset welding length, the motor 45 stops rotating, and the mechanical arm 21 drives the welding gun 22 back to the initial position. The three-jaw chuck 42 and the clamping cylinder 512 are released, and the welded pipe is removed to complete the entire welding process.

It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
