Abstract

The invention belongs to the technical field of pipeline manufacturing and relates to a coaxial positioning jig for a folded edge pipeline. The coaxial positioning jig comprises an expansion body with a cone part and a cylinder part and an adjusting bolt penetrating in the cylinder part from the rear portion of the cylinder part. A sleeve is arranged between the expansion body and the adjusting bolt in a sleeving manner, and the sleeve is provided with a cavity way for the cylinder part to penetrate and multiple square holes evenly distributed around the cavity way. Expansion blocks corresponding to the square holes in number are clamped between the expansion body and the sleeve, and each expansion block is provided with a cone face matched with the cone part. A right-angle-shaped movable frame is fixedly connected to each expansion block, wherein one edge of the movable frame is fixed to the expansion block, and the other edge of the movable frame penetrates in the corresponding square hole and can move in the radial direction of the sleeve. A disc-shaped base is fixed to the face, close to the adjusting bolt, of the sleeve. By means of the coaxial positioning jig for the folded edge pipeline, it can be ensured that the folded edge and the pipeline have good coaxiality and perpendicularity, and the structure of a welded product can better meet the use standards.

Description

technical field [0001] The invention relates to the technical field of pipeline manufacturing, in particular to a coaxial positioning jig for flanging pipelines. Background technique [0002] A large number of pipes are used in the water supply pipeline. Such as figure 1 As shown, the pipe 11 sometimes needs to weld a flange 12 at the mouth of the pipe so that it can be used as a flange. The flanging 12 is a generally annular workpiece with a substantially cylindrical side in the middle for welding with the pipe 11, and the solder 13 is filled between these two parts. However, due to storage problems, the mouth of the pipe 11 often cannot be perfectly round, and direct welding may fail to meet product standards due to poor coaxiality and perpendicularity between the pipe 11 and the flange 12 . [0003] Therefore, it is necessary to provide a positioning fixture to avoid the above problems. Contents of the invention [0004] The main purpose of the present invention is ...
