Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and more specifically, to a visual variable-direction welding gun. Background Technique

[0002] During the construction of offshore oil engineering projects (such as offshore platforms, LNG modules, floating platforms, ship hulls, etc.), welding work is a crucial link. However, due to the influence of the arrival sequence of materials, construction processes, and the spatial limitations of components in some special positions, existing welding equipment often cannot perform effective welding, and there are many welding blind spots.

[0003] Currently, for these welding blind spots, the conventional approach is to remove unimportant structures around the components to be welded. After the components are welded, the removed structures are restored. However, this method has many drawbacks:

[0004] The construction personnel need to continuously adjust the welding posture according to the surrounding structures, which not only takes a lot of time of the construction personnel but also consumes a lot of physical strength, resulting in a significant reduction in construction efficiency. The restoration of the surrounding structures involves secondary construction inspection, which consumes a lot of manpower and material resources and increases the cost of the project. For structures that cannot be removed, welders can only perform blind welding based on experience, which cannot guarantee the welding quality and there are certain quality hazards. Summary of the Invention

[0005] The purpose of the present invention is to provide a visual variable-direction welding gun to solve the problem that the construction personnel need to continuously adjust the welding posture according to the surrounding structures in the above-mentioned background technique, which not only takes a lot of time of the construction personnel but also consumes a lot of physical strength, resulting in a significant reduction in construction efficiency.

[0006] To achieve the above purpose, the present invention provides a visual variable-direction welding gun, including a welding gun. The upper end of the welding gun is connected to a welding head through a universal bend neck. A welding wire is installed at the outer end of the welding head. A display is installed on one side of the lower part of the welding gun. A camera is installed outside the welding head. The camera is connected to the display through a high-definition data cable. The shooting direction of the camera is the same as the welding direction of the welding head.

[0007] Preferably, a holding end is installed at the lower end of the welding gun.

[0008] Preferably, a support frame is installed on the outer wall of the welding head, and the top of the support frame is fixedly connected to the camera.

[0009] Preferably, the universal bend neck is a gooseneck tube structure with an internal cavity, and the wires of the welding gun pass through the universal bend neck and are connected to the welding head.

[0010] Preferably, a positioning assembly is installed on the outer side of the welding torch, and the upper end of the positioning assembly supports and positions the welding head.

[0011] Preferably, the positioning assembly includes a positioning clamp seat. The positioning clamp seat is of a U-shaped structure and is clamped on the outer wall of the welding torch and locked and fixed by a locking bolt. A slider is slidably arranged on the positioning clamp seat, and the outer side of the slider is connected to the outer wall of the welding head through a connecting rod.

[0012] Preferably, a vertical chute is arranged on the outer wall of the positioning clamp seat. A lower pin shaft is rotatably connected to the side wall of the slider, and the end of the lower pin shaft is slidably matched with the chute. The upper end of the connecting rod is rotatably connected to the outer wall of the welding head through an upper pin shaft.

[0013] Preferably, an opening is arranged on one side outer wall of the slider, and a pressing member is arranged at the opening. The slider is fixed by manually pressing the pressing member to realize stable support for the welding head.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] In this visual variable-direction welding torch, through the design of the universal bend neck, the welding head can be adjusted at any angle, enabling the welder to flexibly adjust the angle of the welding torch according to the on-site welding position, greatly improving the flexibility and efficiency of welding. The combination of the camera and the display realizes the real-time visualization of the welding process, and the welder can intuitively see the situation of the welding position, further improving the welding speed and accuracy.

[0016] The camera can capture the images during the welding process in real time and clearly display them through the display. The welder can monitor the welding quality and progress in real time, discover and correct problems in time to ensure the welding quality. Visual monitoring also avoids the quality hidden dangers brought by blind welding and improves the reliability and stability of welding.

[0017] The use of the visual variable-direction welding torch avoids the need to cut and restore the surrounding structures in the traditional method, saving labor and material costs. By improving the welding efficiency and ensuring the welding quality, the possibility of repeated construction and rework is reduced, further reducing the project cost. Real-time visual monitoring enables the welder to more clearly understand the welding environment and avoid the safety risks brought by blind operation. The flexibility of the universal bend neck and the stability of the support frame ensure the equipment safety and personnel safety during the welding process. BRIEF DESCRIPTION OF THE DRAWINGS
