Welding positioning dotter of pipe fittings

Abstract

The invention discloses a welding positioning dotter of pipe fittings. A height gauge of the dotter is welded on a base; a vernier gauge is welded on a fixed ring; a fastening screw is in threaded connection into the fixed ring; a fixed disc is connected with the fixed ring through a stud, and can vertically move along with the fixed ring; an adjustable screw is in threaded connection to the fixed disc; a first slide block is inlaid in a circular chute, and can slide in the circular chute; the circular chute is in spot welding with an angle measuring disc, and is connected to the fixed disc through a self-tapping screw; a second slide block is inlaid in a linear chute; a dotting pen is inlaid in a dotting pen shell; a spring is placed between the dotting pen and a dotting pen end cover; and a level is glued on the fixed disc. The dotter can precisely position welded points of the pipe fittings without a welded bracket.

Description

technical field [0001] The invention relates to a positioning tool in the field of material connection, in particular to a pipe fitting welding positioning inking device. Background technique [0002] With the gradual development of the machinery industry, the structures of various mechanical products are becoming more and more complex, and the pipe fittings of various shapes and their related weldments are also becoming more and more important. Therefore, how to accurately find the position of the welding point of the pipe fitting is an inevitable problem for people. [0003] At present, when the company is making samples for pipe fitting welding, because the product has not yet been put into mass production, the company does not have a complete set of welding molds, so it can only roughly find the position of the welding point with the help of tools such as electronic angle meter and height gauge. They are all round, and some pipe fittings are curved after being formed, s...

Problems solved by technology

[0003] At present, when the company is making samples for pipe fitting welding, because the product has not yet been put into mass production, the company does not have a complete set of welding molds, so it can only roughly find the position of the welding point with the help of tools such as electronic angle gauge and height gauge. They are all round, and some pipe fittings are curved after being formed, so it is difficult to place them on a plane and use a height ruler to mark the line. We can only use fixtures such as three-jaw chucks to fix the pipe fittings and then mark the lines. The surface roughness is high, and there will be uneven phenomena when placed on the inspection table, which will cause errors. It is also difficult to find a precise reference when using a goniometer to find the welding point. You can only roughly find the welding point and perform spot welding, and then adjust it. , which takes a lot of time, is inefficient, and quite inconvenient

At present, there is no innovative invention of a pipe welding point positioner that can complete the precise positioning of pipe welding points in one process and has a flexible clamping device.
