Girth welding tool

Abstract

The invention provides a girth welding tool. The girth welding tool comprises a support rack and a clamping mechanism arranged on the support rack, wherein the clamping mechanism comprises a pluralityof support columns, which are arranged obliquely correspondingly on the support rack, and guide wheels, which are mounted rotationally on the support columns; one ends of the support columns are rotationally mounted on the support rack; mounting grooves for mounting the guide wheels are formed in the other ends of the support columns; the guide wheels are mounted on the support columns through rotating shafts; positioning plates are arranged on the supporting columns in the rotation direction of the guide wheels; and a cover plate assembly is arranged at the position, corresponding to the support columns, on the support rack. The girth welding tool can be well applied to the girth welding of a workpiece and well restrict the transverse movement of the workpiece to ensure the welding quality of the workpiece; meanwhile, the workpiece can rotate axially on the girth welding tool, which is convenient for a worker to weld the workpiece quickly; and the support columns and the guide wheelson the support columns can support the workpiece well, and the guide wheels, which are arranged in an rotatable manner, also allow the workpiece to be moved easily on the support columns.

Description

Technical field [0001] The invention belongs to the field of welding tooling, and in particular relates to a circumferential seam welding tooling. Background technique [0002] With the acceleration of my country's industrial modernization, welding technology and welding level have been developed and improved rapidly. Welding has penetrated into all walks of life and all aspects of industrial production. Welding has important and extensive applications in mechanical design and manufacturing departments such as electric power and energy. The level of welding technology and equipment has become a standard for measuring a country’s industrial level. Welding equipment is developing towards mechanization and standardization, and is constantly being improved. The existing welding tooling generally adopts clamping type, which is directly clamped and fixed by clamping blocks. Workpieces are not easy to adjust on the tooling, and it is not easy to adjust the fixed welding position. Worke...

Problems solved by technology

The level of welding process equipment has become a standard to measure a country's industrial level. Welding equipment is developing towards mechanization and standardization, and is constantly being improved. The existing welding equipment generally adopts clamping type, which is directly clamped and fixed by clamping blocks. The workpiece, the workpiece is not easy to adjust on the tooling, and it is not easy to adjust the fixed welding position. The worker needs to constantly adjust the workpiece when welding, which is very troublesome to operate, and it is easy to cause welding interruption, which greatly affects the efficiency of workpiece welding
