Steel bar welding calibration device

Abstract

The invention provides a steel bar welding alignment device, which includes a first alignment structure, a second alignment structure and a top limiting structure. The first alignment structure and the second alignment structure are arranged opposite to each other and can face each other. Sliding horizontally, the first alignment structure and the second alignment structure are both provided with alignment parts, the alignment parts move closer to each other to clamp and position the two welding points of the steel bars, and the top limit structure It is arranged between the first alignment structure and the second alignment structure, and is used to limit the vertical position of the top protrusion of the steel bar. The invention automatically completes the correction of the two welding points of the steel bar through two sets of mutually coordinated alignment structures and top limit structures, so that the welding point of the steel bar is aligned with the welding position of the steel pipe, the positioning accuracy of the welding point is improved, and the truss is automatically welded. accuracy and quality.

Description

technical field [0001] The invention relates to the technical field of steel bar processing and welding, in particular to a steel bar welding calibration device. Background technique [0002] A truss is a support structure widely used in large-scale transportation buildings such as houses, bridges, and ships. A truss composed of straight rods generally has a planar or spatial frame form of triangular units. The straight bar of the truss mainly bears axial tension or pressure, which can make full use of the strength of the material, while the web bar usually adopts a steel bar structure. The web bar of this steel bar structure is usually M-shaped, such as image 3 As shown, the steel bars of this shape can form a triangular structure in the truss structure, thereby bearing greater bending stress. The production of such trusses requires the welding of steel bars to steel pipes used as straight rods. [0003] In the prior art, the automatic welding of the steel bar and the mai...

Problems solved by technology

Due to the large size of the steel pipe and the steel bar, usually more than 10 meters, it is easy to deviate from the position during the feeding process of the steel bar, and the M-shaped steel bar will also produce a certain elastic deformation when it is transported, which will affect the alignment of the welding points, resulting in Obvious welding errors, reducing welding quality
