Technical Field

[0001] The utility model relates to the technical field of pipe pile welding, in particular to an automatic pipe pile welding machine. Background Technique

[0002] With the development of the manufacturing industry, the application of automatic welding devices in the welding field has become increasingly important. Automatic welding devices can greatly improve the efficiency of welding operations, the safety of workers, and the quality consistency. In the traditional manual welding process, welders are faced with long-term exposure to high temperatures, noise, ultraviolet radiation, and possible harmful gases, which not only affect the physical health of welders but also limit the improvement of production efficiency and welding quality.

[0003] At present, pipe pile welding operations are basically still carried out manually. Not only is the working risk of workers high, but the quality also cannot be guaranteed. It is a challenge for current automatic welding devices to ensure welding quality, simplify the structure of the automatic welding device, reduce the failure rate, and achieve lightweight.

[0004] Therefore, it is necessary to develop an automatic pipe pile welding machine to improve the problems existing in the prior art. Content of the Utility Model

Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings as understood by those of ordinary skill in the art in the field to which the present utility model belongs. The words such as "including" used herein mean that the elements or items appearing before this word cover the elements or items listed after this word and their equivalents, without excluding other elements or items.

[0023] The embodiments of the present utility model provide an automatic pipe pile welding machine, which includes a fixed ring 1. The fixed ring 1 is fixedly installed on a pipe pile through a bolt fixing assembly. A connecting iron sheet 3 is fixedly connected to the fixed ring 1. A welding track assembly is connected to the connecting iron sheet 3. A welding cart 5 is installed on the welding track assembly and makes a circular motion on the welding track assembly. A first track 6 is fixedly connected to the top of the welding cart 5. A first slider 61 is slidably connected in the first track 6. An L-shaped block 62 is fixedly connected to the first slider 61. A first lead screw 63 is rotatably connected in the first track 6. The first lead screw 63 is connected to a first motor 64 through a coupling. A second track 65 is fixedly connected to the L-shaped block 62. A second slider 66 is slidably connected in the second track 65. A second lead screw 67 is rotatably connected in the second track 65. The second lead screw 67 is connected to a second motor 68 through a coupling. An extension rod 69 is connected to the second slider 66. A welding torch 7 is arranged at one end of the extension rod 69 away from the second slider 66.

[0024] In some embodiments, the welding torch 7 is fixed to one end of the extension rod 69 away from the second slider 66 through bolts. By removing the bolts, the position of the welding torch 7 can be adjusted.

[0025] In some embodiments, the fixed ring 1 is composed of two semi-rings fixedly connected through bolts and nuts.

[0026] In some embodiments, the bolt fixing assembly includes a fixing block 2, a graduated bolt 21 and a base 22. The fixing block 2 is connected to the fixing ring 1 by bolts. The fixing block 2 is rotatably connected to the graduated bolt 21. One end of the graduated bolt 21 away from the fixing block 2 is threadedly connected to the base 22, and the base 22 is used to abut against the pipe pile.

[0027] In some embodiments, a rubber gasket is provided at one end of the base 22 close to the pipe pile.

[0028] In some embodiments, a retaining pin is connected between the graduated bolt 21 and the base 22.

[0029] By combining the welding track assembly with a long bolt with graduations and a rubber sheet at the end, tightening the long bolt can fasten the bolt fixing assembly to the pipe pile. At the same time, since the welding track assembly avoids the welding work on the ring and the long bolt has graduations, the concentricity of the fixing ring and the pipe pile is ensured.

[0030] In some embodiments, the welding track assembly includes a disc 4 and a gear track 41. The disc 4 is connected to the fixing ring 1 through a connecting iron sheet 3. The disc 4 is also composed of two semi - rings. The disc 4 is fixedly connected with the gear track 41. The gear track 41 is composed of two semi - rings with external teeth. When the fixing ring 1 is opened, the disc 4 and the gear track 41 are also opened to form a semi - open trolley track. A third motor 42 is installed in the welding trolley 5. A pinion 43 is connected to the output shaft of the third motor 42, and the pinion 43 meshes with the gear track 41. Symmetrically distributed rollers 44 are provided at the bottom of the welding trolley 5, and the rollers 44 are in contact and cooperation with the disc 4.

[0031] In some embodiments, a rectangular block 45 is provided at the bottom of the welding trolley 5, and the rectangular block 45 is slidably connected to the disc 4.

[0032] The semi - open trolley track is connected to the fixing ring 1 through the connecting iron sheet 3, and the welding trolley 5 is arranged above the disc 4. The gear track 41 and the disc 4 are simplified, reducing the weight. The structure and installation method of the welding trolley 5 are improved. Rollers are added, changing the sliding friction between the welding trolley 5 and the disc 4 into rolling friction, reducing the wear between the kinematic pairs. And a rectangular block 45 is added, increasing the connection reliability, making the circular motion of the welding trolley 5 more reliable, reducing the overall weight while strengthening the reliability of the mechanism and reducing the failure rate.

[0033] A double - slide - rail structure is adopted to control the degrees of freedom of the welding torch 7 in the radial and axial directions of the pipeline, improving the welding accuracy. And the motor drives the lead screw to drive the slider to move, making the movement of the welding torch 7 more stable and rapid.

[0034] In some embodiments, the first motor 64 and the second motor 68 are attached with brake accessories to ensure that the movement of the mechanism can be immediately stopped when power is cut off, thereby improving safety.

[0035] Although the embodiments of the present invention have been described in detail above, it is obvious to those skilled in the art that various modifications and changes can be made to these embodiments. However, it should be understood that such modifications and changes are all within the scope and spirit of the present invention described in the claims.
