Automatic centering auxiliary supporting and positioning device for steel pipe welding

Abstract

The invention relates to the technical field of steel pipe welding and positioning equipment, in particular to an automatic centering auxiliary supporting and positioning device for steel pipe welding. The automatic centering auxiliary supporting and positioning device comprises a machining table, a driving shaft is rotatably connected into the machining table, a special-shaped gear is connected with the right side surface of the driving shaft in a meshing mode, and a horizontal toothed plate is connected with the lower surface of the special-shaped gear in a meshing mode; and the right side face of the horizontal toothed plate is fixedly connected with a positioning supporting plate, and the front surface of the special-shaped gear is movably connected with a crank connecting rod through a shaft. Steel on two sides moves synchronously, then the horizontal center lines of the steel on two sides are located on the same straight line, then automatic centering can be well conducted on the steel, and thus the effect of automatic centering of the steel is achieved; and meanwhile, the application range of equipment is widened, it is guaranteed that the distance between a welding head and the outer surfaces of the steel with different diameters is a fixed value, the precise welding effect is achieved, the steel deformation detection effect is achieved, and therefore the working effect of the equipment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of steel pipe welding positioning equipment, in particular to an automatic centering auxiliary support positioning device for steel pipe welding. Background technique [0002] Steel is used in different fields in our life. Steel has become one of the most used materials in the world due to its low price and reliable performance. It is an indispensable component in construction, manufacturing and people's daily life. Steel The chemical composition can vary greatly, and steel containing only carbon elements is called carbon steel (carbon steel) or ordinary steel; in actual production, steel often contains different alloying elements according to different uses. [0003] However, the existing equipment cannot ensure that the center of the steel is at the same point when positioning the steel, the degree of automation is low, and the automatic centering cannot be well realized. Moreover, the welded steel cannot ...

Problems solved by technology

[0003] However, the existing equipment cannot ensure that the center of the steel is at the same point when positioning the steel, the degree of automation is low, and the automatic centering cannot be well realized. Moreover, the welded steel cannot be well aligned. Detect whether it is deformed, which may affect the quality of the steel; therefore, those skilled in the art provide a self-centering auxiliary support positioning device for steel pipe welding to solve the problems raised in the above-mentioned background technology
