Problems solved by technology

[0002] When positioning welding between the existing flange and the elbow, just put the flange on the workbench, then directly place the elbow in the flange hole, and fix it by spot welding after visual inspection is roughly perpendicular to the flange. It is necessary to hold the elbow with one hand to prevent the elbow from bowing, and when adjusting the diagonal spot welding of the elbow, it is easy to cause cracking of the solder joint when turning, the efficiency of positioning welding is low, and the welding quality is low

Abstract

The invention discloses a fixed-position welding device for a flange and an elbow. The fixed-position welding device consists of a base, an operation rotary table, a support and a bearing, wherein a hole for mounting a bearing is formed in the upper surface of the base; a flange positioning stand column is arranged on the operation rotary table; the operation rotary table is mounted on the base through the bearing; the support is welded and fixedly arranged on the operation rotary table; when the flange and the elbow are subjected to fixed-position welding, the flange passes through the positioning stand column, and is put on the operation rotary table, then, one end of the elbow is inserted into a flange hole, the other end of the elbow is put on the support, one point is positioned after regulating for welding and fixing, the operation rotary table is rotated, and the other point for angular point welding is fixed, so that positioning welding efficiency between the flange and the elbow is effectively improved; and moreover, positioning welding quality between the flange and the elbow is guaranteed, and the below subjected to point welding is prevented from a bowing phenomenon.

Description

technical field [0001] The invention mainly relates to rapid positioning welding between a flange and an elbow, and belongs to the technical field of pipe fitting welding. Background technique [0002] When positioning welding between the existing flange and the elbow, just put the flange on the workbench, then directly place the elbow in the flange hole, and fix it by spot welding after visual inspection is roughly perpendicular to the flange. It is necessary to hold the elbow with one hand to prevent the elbow from bowing, and when adjusting the diagonal spot welding of the elbow, it is easy to cause cracking of the solder joint when turning, the efficiency of positioning welding is low, and the welding quality is low. Contents of the invention [0003] The object of the present invention is to provide a flange and elbow positioning welding device with simple structure, easy processing and production, and convenient operation and use. [0004] A flange and elbow positio...
