Problems solved by technology

The method of drawing intersecting lines by hand relying on experience has the defects of high labor intensity, low labor efficiency and low precision of line drawing. Due to the low precision of the drawn intersecting lines, it will also cause corresponding problems to the subsequent process. However, the method of drawing intersecting lines using templates, although the accuracy of the drawn intersecting lines is high, but because different diameters of pipes must prepare different templates, there is a long preparation time for labor and production costs higher defect

Abstract

The invention discloses an intersecting line drawing tool, belonging to the technical field of mechanical fitter tools. The technical scheme is as follows: two V-shaped chucks are installed and fixed on a pipeline to be drawn with an intersecting line in advance, a scriber of which the position can be regulated freely is installed and fixed on one V-shaped chuck, and the scriber and the pipeline to be connected are regulated to be in the same included angle, thereby drawing out the intersecting line. The intersecting line drawing tool disclosed by the invention has the advantages of higher line drawing efficiency and higher accuracy and simultaneously can adapt to pipelines of different diameters.

Description

technical field [0001] The invention relates to a line drawing tool, in particular to a line drawing tool for intersecting lines, and belongs to the technical field of mechanical fitter tools. Background technique [0002] In water, electricity, gas or other engineering construction, as well as other mechanical manufacturing technology fields, it is often necessary to weld the axes in the same plane; and the steel pipes with axes at different angles are welded together. Draw the intersecting line at the junction of two steel pipes, and then remove the excess material enclosed by the intersecting line according to the drawn intersecting line, so as to facilitate the welding of two intersecting steel pipes. At present, in the method for drawing the above-mentioned intersecting lines, mainly rely on manual experience or the method of using templates. The method of drawing intersecting lines by hand relying on experience has the defects of high labor intensity, low labor effici...
