DETAILED DESCRIPTION

[0055] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0056] First, the terms involved in this application are explained:

[0057] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure; there are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasonic.

[0058] Pipeline refers to the pipe that transmits the working fluid in the hydraulic system. Compared with pipeline, pipeline is a reasonably arranged pipeline system. Because of the flexibility of pipeline, pipeline is often used in hydraulic system and other mechanical equipment driven by liquid.

[0059] A three-jaw chuck refers to a machine tool accessory that uses the radial movement of three movable jaws evenly distributed on the chuck body to clamp and position the workpiece.

[0060] The electric cylinder is a modular product that integrates the servo motor and the lead screw. It converts the rotational motion of the servo motor into linear motion to achieve a series of high-precision linear motion products.

[0061] As described in the background technology, the pipe welding device in the related technology includes a plate body and multiple sets of pipe clamping mechanisms arranged on the plate body. The pipes are clamped by the multiple sets of pipe clamping mechanisms so that the ports of the pipes are connected to each other, and then the pipes are circumferentially welded by manually taking the welding gun.

[0062] However, the above-mentioned method of manually holding the welding gun for pipeline ring welding requires manual holding of the welding gun and moving the welding gun along the circumference of the pipeline. It is difficult to manually control the distance between the welding end of the welding gun and the pipeline, resulting in reduced welding quality of the pipeline ring welding; and the method of manually holding the welding gun wastes manpower.

[0063] In response to the above technical problems, an embodiment of the present application provides a pipeline ring welding device, which adjusts the position of the laser welding gun through a first adjustment mechanism, a second adjustment mechanism and a third adjustment mechanism, so that the laser welding gun can be located at different positions to weld the pipeline, and the setting of the first adjustment mechanism, the second adjustment mechanism and the third adjustment mechanism can maintain the same welding distance between the pipeline, thereby improving the welding quality of the pipeline, and the setting of the adjustment component can adjust the welding angle of the laser welding gun, so that the laser welding gun can weld at different angles when welding the pipeline, thereby further improving the welding quality of the pipeline; the pipeline is clamped by the pipeline clamping mechanism, and the pipeline is rotated by the active rotation mechanism, so that the welding mechanism can further weld different positions of the pipeline, thereby further improving the welding quality of the welding mechanism for welding different positions of the pipeline.

[0064] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments.
