Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually illustrative only and in no way limits the present invention and its application or use. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0035] As Figures 1 to 3 shown, the embodiment of the present invention provides a pipeline welding auxiliary device, and the pipeline welding auxiliary device includes a workbench 10, a lifting part 20, a clamping assembly and a buffer part 40. Among them, the lifting part 20 is arranged on the workbench 10 in a liftable manner, and the lifting part 20 is used to support the pipeline. The clamping assembly is arranged on the workbench 10 and is located on one side of the lifting part 20. The clamping assembly includes two relatively arranged clamping parts 30, and the distance between the two clamping parts 30 is adjustable. The two clamping parts 30 cooperate with each other to clamp the pipeline. The buffer part 40 is arranged on at least one clamping part 30, the buffer part 40 is located between the two clamping parts 30, and the buffer part 40 is used to abut against the pipeline.

[0036] Applying the technical solution of the present invention, by setting the lifting part 20 and the clamping assembly, the positioning of the pipeline can be realized, and there is a gap between the pipeline and the tabletop of the workbench 10, which is convenient for the welding device to weld the pipeline. Setting the pipeline on the lifting part 20 can further facilitate the adjustment of the height of the pipeline, that is, the adjustment of the height of the axis of the pipeline. Moreover, setting the clamping assembly in the form of two clamping parts 30 enables the clamping assembly to clamp pipelines with different diameters. During the welding process, under the action of the welding device, the pipeline may shake. The setting of the buffer part 40 can buffer the pipeline, reduce the shaking of the pipeline, improve the stability of the pipeline during welding, and further improve the welding quality. Compared with the traditional technical solution, the setting of this solution can improve the stability of the pipeline during welding and improve the welding quality.

[0037] Specifically, the buffer part 40 includes a buffer plate 41 and a spring member 42. Among them, the buffer plate 41 is arranged on one side of the clamping part 30 close to the other clamping part 30. The buffer plate 41 includes an arc-shaped plate, and the arc-shaped plate is adapted to the circumferential profile of the pipeline. The spring member 42 is arranged between the buffer plate 41 and the corresponding clamping part 30. One end of the spring member 42 is connected to the buffer plate 41, and the other end is connected to the clamping part 30. With such a setting, the structure is simple, the contact area between the buffer plate 41 and the pipeline is as large as possible, and the stability of the clamping between the buffer plate 41 and the pipeline is improved.

[0038] Further, the spring member 42 includes a connection block 421 and a buffer spring 422. The connection block 421 is arranged on the buffer plate 41. One end of the buffer spring 422 is connected to the connection block 421, and the other end of the buffer spring 422 is connected to the corresponding clamping part 30. The pipeline welding auxiliary device further includes a protective sleeve 50. One end of the protective sleeve 50 is arranged on the clamping part 30, and the other end of the protective sleeve 50 is sleeved on the buffer spring 422 and part of the connection block 421. The connection block 421 and the protective sleeve 50 are arranged to slide relative to each other. The buffer spring 422 expands and contracts along the direction from the clamping part 30 to the buffer plate 41. With such a setting, the protective sleeve 50 protects the buffer spring 422, reducing the possibility of the buffer spring 422 being damaged.

With such a setting, the smoothness of the buffer spring 422 during the expansion and contraction process can be further improved, ensuring the stability of the contact between the buffer plate 41 and the pipeline, and improving the stability of the pipeline during the welding process.

[0041] Specifically, the protective sleeve 50 is provided with a guiding groove, and one end of the connection block 421 close to the buffer spring 422 is provided with a guiding protrusion. The guiding protrusion is movably inserted into the guiding groove to realize the guiding cooperation between the protective sleeve 50 and the connection block 421.

[0042] Further, the pipeline welding auxiliary device further includes a first driving component 60. The first driving component 60 is arranged on the workbench 10, and the first driving component 60 is drivingly connected to at least one clamping part 30 to adjust the distance between the two clamping parts 30.

[0043] Specifically, the first driving assembly 60 includes a bidirectional lead screw 61 and two nuts 62. The bidirectional lead screw 61 is rotatably arranged on the top of the workbench 10. A first thread section and a second thread section are arranged on the surface of the bidirectional lead screw 61. The first thread section and the second thread section are distributed along the axial direction of the bidirectional lead screw 61, and the thread directions of the first thread section and the second thread section are different. The two nuts 62 are respectively threadedly connected to the first thread section and the second thread section, and each nut 62 is provided with a clamping portion 30. With such a setting, the structure is simple, and there is also a self-locking function between the bidirectional lead screw 61 and the nut 62, which can improve the stability of the clamping portion 30 when it is in a static state and enhance the stability of clamping the pipeline.

[0044] In an embodiment of this solution, a fixing screw 90 is further included. After the two clamping portions 30 clamp the pipeline, the two clamping portions 30 are fixed by the fixing screw 90. With such a setting, the stability of the clamping portion 30 clamping the pipeline can be further improved.

The driving screw 83 is arranged on the second-end bevel gear, and the driving screw 83 extends in the vertical direction. The lifting portion 20 is threadedly connected to the driving screw 83. With such a setting, the structure is simple, the operation is more convenient, and the bevel gear assembly 82 and the driving screw 83 respectively have a self-locking function. The above settings can ensure the stability of the lifting portion 20 when it is in a static state and ensure the stability of clamping the pipeline.

[0048] In an embodiment of the present solution, an installation cavity is provided inside the workbench 10. The bottom end of the lifting part 20 can pass through the top plate of the workbench 10 and extend into the installation cavity. The bottom end of the lifting part 20 includes a connecting plate.
