Improved end cover welding tool for barrel

Abstract

The invention relates to the technical field of end cover machining, in particular to an improved end cover welding tool for a barrel. The tool comprises a machining table and a barrel support, and further comprises two positioning adjustment stepping mechanisms, wherein the barrel support is fixedly mounted at the center of the top of the machining table, the barrel support is provided with an arc-shaped accommodating groove capable of accommodating the barrel, and the two positioning adjustment stepping mechanisms are arranged at the two ends of the barrel support correspondingly; and each positioning adjustment stepping mechanism comprises a height adjusting assembly, a rotating assembly, a positioning clamping assembly, and a horizontal moving assembly, each horizontal moving assemblyis fixedly mounted on the machining table, each height adjusting assembly is located above the corresponding horizontal moving assembly, the bottom of each height adjusting assembly is fixedly connected with the working end of the corresponding horizontal moving assembly, and each rotating assembly is located inside the corresponding height adjusting assembly. Each end cover needing to be welded can be stably clamped by the device, the height of each end cover can be adjusted, and the accuracy of welding between each end cover and the barrel is improved.

Description

Technical field [0001] The invention relates to the technical field of head processing, in particular to an improved cylindrical head welding tool. Background technique [0002] The head refers to the element used to close the end of the container to isolate the internal and external media. It is also called an end cap. The head of a cylindrical container is generally a rotating shell. According to the shape of the head surface, it can be divided into convex, Cone, flat and combined shapes. Convex heads refer to heads whose outer surface is convex, such as hemispherical, elliptical, dish-shaped and spherical heads without flanges. Some gas cylinders use convex inward The combined bottom head can not only ensure the strength, but also meet the requirements of safe use. The head is a part of the container and is connected to the cylinder by welding. One of the cylinders needs to be welded on both ends of the head. When the existing head welding tooling is performed on both ends of...

Problems solved by technology

[0002] The head refers to the component used to close the end of the container to isolate the internal and external media, also known as the end cover. The head of the cylindrical container is generally a rotating shell, which can be divided into convex, Conical, flat and combined shapes. Convex heads refer to heads whose outer surface is convex, such as hemispherical, elliptical, dish-shaped and spherical heads without folds. Some cylinders use convex inwards. The combined bottom head can not only ensure the strength, but also meet the needs of safe use. The head is a part of the container, which is connected to the cylinder by welding. One of the cylinders needs to be welded to both ends of the cylinder. In the existing head welding tooling for both ends of the cylinder, the cylinder is placed horizontally on the cylinder bracket to position it, and the two heads are respectively moved to the two ends of the cylinder through the claws and the moving mechanism , so that the two ends of the cylinder are butted, and then welded by a welding machine. However, the existing technology cannot adjust the head that needs to be welded, which will easily cause the gap between the cylinder and the head to be different, and it is easy to weld Bring bad products, therefore, we propose an improved cylinder head welding tooling to solve the problems raised above
