Non-standard bent pipe and flange welding positioning tool

Abstract

The invention relates to the technical field of tool clamps, and discloses a non-standard bent pipe and flange welding positioning tool. The non-standard bent pipe and flange welding positioning toolcomprises a bottom plate, wherein a plurality of height-adjustable supporting legs are arranged at the bottom of the bottom plate, a bent pipe positioning plate distributed in parallel is arranged above the top face of the bottom plate, supporting columns are arranged at the two sides of the middle of the bent pipe positioning plate, and the lower ends of the supporting columns are fixedly connected with the bottom plate. The upper ends of the supporting columns are rotationally connected with the bent pipe positioning plate, an angle adjusting mechanism used for adjusting the angle of the bent pipe positioning plate is arranged between the left end of the bent pipe positioning plate and the bottom plate, and a bent pipe clamping mechanism and a bent pipe centering mechanism are arranged on the bent pipe positioning plate. Supports are arranged at the two ends of the bottom plate, sliding rods parallel to the bottom plate are arranged between the upper ends of the supports, a sliding base is arranged between the sliding rods, and a flange positioning adjusting mechanism is arranged on the sliding base; and a level gauge is further arranged on the bottom plate. According to the non-standard bent pipe and flange welding positioning tool, the high-precision positioning of a flange and a bent pipe can be achieved, it is guaranteed that the welding consistency of the flange and thebent pipe is good, and the welding quality is high.

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...

AI Technical Summary

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
