Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline laser welding tooling, and in particular relates to a protective tooling for pipeline laser welding. Background Art

[0002] Pipeline laser welding is a high-precision and high-efficiency welding technology that usually requires the use of fixtures to fix and support the pipeline to ensure stability and accuracy during the welding process. The fixture is usually designed to be adjustable and rotatable so that the pipeline can achieve the best welding angle and position. However, if the fixture is improperly designed or used, it may cause difficulties in adjusting the welding angle when the pipeline is rotated. This may be due to the fact that the adjustment device of the fixture is not flexible enough, or the structure of the fixture itself limits the freedom of the pipeline during rotation. This problem will make it difficult to adjust the welding angle during welding, which may affect the quality and efficiency of welding. Utility Model Content

[0003] In order to overcome the problem that the existing fixtures for laser welding of pipelines cannot rotate, which makes it inconvenient to adjust the position of the laser welding pipeline.

[0004] The technical scheme of the utility model is: a protective tooling for pipeline laser welding, comprising a pipeline clamping base assembly, a pipeline pressing clamping assembly, an angle adjustment servo driver, and a small pipeline clamp; angle adjustment servo drivers are arranged on both sides of the pipeline clamping base assembly, and the output end of the angle adjustment servo driver is transmission-connected with the outer shell of the pipeline clamping base assembly; the upper end of the pipeline clamping base assembly is provided with a pipeline pressing clamping assembly; fixed pulleys are arranged on both sides of the upper end surface of the pipeline clamping base assembly, and a servo motor in the angle adjustment servo driver drives the outer shell of the pipeline pressing clamping assembly to rotate, thereby realizing the overall rotation angle adjustment of the pipeline pressing clamping assembly, greatly improving the angle adjustment adaptability between the device and the laser welding machine, and improving the flexibility of the angle adjustment.

[0005] Preferably, the pipe clamping and rotation adjustment functions are realized by the pipe pressing clamping assembly, which solves the problem of inconvenience in adjusting the position of the laser welded pipe due to the inability of the pipe clamp to rotate in the existing pipe laser welding fixture.

[0006] Preferably, the pipe pressing clamping assembly includes a lifting column, an adjusting bracket, a lifting screw, a lifting threaded sleeve, a pipe clamping rod, and a horizontally movable adjusting screw; a lifting column is provided at the upper end of the pipe clamping base assembly, and the lifting column is fixedly connected to the pipe clamping base assembly.

[0007] Preferably, a lifting screw is arranged inside the lifting column, and the lifting screw is rotationally connected to the inner wall bearing of the lifting column; a servo motor is arranged at the upper end of the lifting screw, and the output end of the servo motor is transmission-connected to the lifting screw.

[0008] Preferably, an adjusting bracket is sleeved on the outer side of the lifting screw, and the adjusting bracket is threadedly connected to the lifting screw, and the adjusting bracket is lifting and slidingly connected to the inner wall of the lifting column.

[0009] Preferably, a lifting threaded sleeve is provided inside the adjusting bracket, and the lifting threaded sleeve is horizontally slidably connected along the inner wall of the adjusting bracket; a horizontally movable adjusting screw is provided at one end of the outer side of the adjusting bracket, and the horizontally movable adjusting screw passes through the outer shell of the lifting threaded sleeve, and the horizontally movable adjusting screw is threadedly connected to the outer shell of the lifting threaded sleeve, and the rotation of the lifting threaded sleeve is utilized to lock the pipe clamp rod on the upper end face of the pipe.

[0010] Preferably, a pipe clamping rod is provided at the lower end of the lifting threaded sleeve, and the lifting threaded sleeve is rotatably connected to the pipe clamping rod. Since the pipe clamping rod and the fixed pulley are rotatable, the function of simultaneously clamping the pipe and performing rotational adjustment is achieved.

[0012] Beneficial effects of the utility model:

[0013] The existing fixture for laser welding of pipelines has the problem that it is inconvenient to adjust the position of the laser welding pipeline because the pipeline clamping cannot rotate. First, the pipeline is placed on the fixed pulley at the upper end of the pipeline clamping base assembly, and then the lifting threaded sleeve is driven by the rotating horizontal movement adjustment screw to horizontally move the adjusting pipe clamping rod along the inner wall of the adjusting bracket to adjust the horizontal position of the pipe clamping rod. After that, the servo motor above the pipeline pressing clamping assembly drives the lifting screw to rotate, and the rotating lifting screw drives the adjusting bracket to drive the thread transmission, thereby realizing that the adjusting bracket drives the pipe clamping rod to press and clamp the pipeline, and finally the lifting threaded sleeve is rotated to lock the pipe clamping rod on the upper end face of the pipeline. Since the pipe clamping rod and the fixed pulley can rotate, the function of rotating and adjusting the pipe while clamping the pipeline is realized. This solves the problem that the existing fixture for laser welding of pipelines has the problem that it is inconvenient to adjust the position of the laser welding pipeline because the pipeline clamping cannot rotate.

[0014] Through the setting of the angle adjustment servo driver, the servo motor in the angle adjustment servo driver drives the outer shell of the pipe pressing and clamping assembly to rotate, thereby realizing the overall rotation angle adjustment of the pipe pressing and clamping assembly, greatly improving the angle adjustment adaptability between the device and the laser welding machine, and improving the flexibility of the angle adjustment.
