A non-standard elbow flange welding positioning tool

Abstract

The invention relates to the technical field of tooling and fixtures, and discloses a non-standard elbow flange welding positioning tool, which includes a bottom plate, a number of height-adjustable support feet are provided at the bottom of the bottom plate, and parallel distributed elbows are arranged above the top surface of the bottom plate. Positioning plate, the middle sides of the elbow positioning plate are provided with support columns, the lower end of the support column is fixedly connected with the bottom plate, the upper end of the support column is rotationally connected with the elbow positioning plate, and there is a set between the left end of the elbow positioning plate and the bottom plate An angle adjustment mechanism for adjusting the angle of the elbow positioning plate. The elbow positioning plate is equipped with an elbow clamping mechanism and an elbow centering mechanism; there are brackets at both ends of the bottom plate, and a slide parallel to the bottom plate is provided between the upper ends of the brackets. A sliding seat is provided between the sliding rods, and a flange positioning adjustment mechanism is provided on the sliding seat; a level is also provided on the bottom plate. The invention can realize the high-precision positioning of the flange and the bent pipe, and ensure good welding consistency and high welding quality of the flange and the bent pipe.

Description

technical field [0001] The invention relates to the technical field of tooling fixtures, in particular to a non-standard elbow flange welding positioning tooling. Background technique [0002] Flange connection is a commonly used connection method between pipelines. Many boilers are equipped with many connecting pipes. The outer ends of the connecting pipes need to be welded with flanges for the connection of external pipelines. Because the connecting pipes are usually used to transport liquid or gas Medium, so the tightness of the flange connection is very high, which requires high welding precision between the flange and the end of the connecting pipe. Although the common connecting pipes are straight pipes or 90° elbows, this kind of connecting pipes and flanges are welded and positioned more conveniently, and general clamping and positioning tools can position the connecting pipes and flanges. However, many connecting pipes are non-standard elbows, for example, the angl...

Problems solved by technology

However, many connecting pipes are non-standard elbows, for example, the angle of the elbow is 120°, 135°, 150° or even other angles. For accurate positioning of the flange, it is necessary to repeatedly adjust the position of the flange and the end of the elbow based on subjective experience, and the consistency between the welded flange and the elbow is poor and the precision is low, which seriously affects the overall quality
