Abstract

The invention belongs to the technical field of pipeline manufacturing, and relates to a coaxial positioning jig for flanging pipelines, which includes an expansion body with a cone and a cylinder and an adjusting bolt that penetrates from the rear of the cylinder. A sleeve is set between the adjusting bolts, and the sleeve is provided with a cavity for the cylinder to penetrate and a number of square holes evenly distributed around the cavity, and the expansion body and the sleeve are clamped Hold expansion blocks corresponding to the number of square holes, each expansion block has a tapered surface that matches the taper, and a right-angle movable frame is fixed on the expansion block, and one side of the movable frame is connected to the expansion block. The block is fixed, and the other side penetrates the square hole and can move radially along the sleeve, and the sleeve is fixed with a disc-shaped base on the side close to the adjusting bolt. The invention can ensure good coaxiality and perpendicularity between the flanging and the pipeline, so that the structure of the welded product is more in line with the use standard.

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 ...
