Stable butt joint device for pipe fitting welding

Abstract

The invention is suitable for the technical field of pipe fitting welding, and provides a pipe fitting welding stable butt joint device which comprises a device base and further comprises a moving mechanism, the moving mechanism comprises a first moving assembly and a second moving assembly, the first moving assembly is connected with a clamping mechanism, and the second moving assembly is connected with a lifting rotating mechanism; the lifting and rotating mechanism is fixedly connected with the centering mechanism; and the centering mechanism comprises a centering seat, a power piece, a second transmission module, a first rotating piece, a driving seat, a first threaded shaft, a centering assembly, an abutting piece and a limiting seat. According to the stable butt joint device for pipe fitting welding, through the moving mechanism, the lifting rotating mechanism, the clamping mechanism and the centering mechanism, centering butt joint of two sets of pipe fittings can be achieved, the central axes of the two sets of pipe fittings coincide, the perpendicularity of the pipe fittings after welding is guaranteed, the welding quality and efficiency of the pipe fittings are improved, and the production rejection rate of the pipe fittings is reduced; and the production economic cost is saved.

Description

Technical field [0001] The present invention belongs to the field of pipe welding technology, in particular to a pipe welding stable docking device. Background [0002] China is already the world's largest producer and consumer of building materials, the main building materials products, such as cement, flat glass, building sanitary ceramics, stone and wall materials, etc., the output has ranked first in the world for many years; The quality of building materials products is constantly improving, energy and raw material consumption is declining year by year, various new building materials are emerging, building materials products are constantly upgraded, and pipe fittings are also constantly upgraded. Pipe fittings are the general term for the components in the pipeline system that connect, control, change direction, divert, seal and support; According to the different processing technology, it is divided into four categories, namely, butt welded pipe fittings (divided into two k...

AI Technical Summary

Problems solved by technology

[0003] The existing pipe fitting welding stable docking device is equipped with a clamping mechanism and a moving mechanism. The two sets of clamping mechanisms respectively clamp and fix the two sets of pipe fittings. The moving mechanism drives the two sets of clamping mechanisms to approach each other, thereby realizing the docking of the two sets of pipe fittings. , to facilitate its welding; the existing device ignores the unevenness of the cross-section of the two sets of pipe fittings when butt jointing the two sets of pipe fittings, which will cause the central axes of the two sets of pipe fittings to not coincide after welding, resulting in pipe fittings Bending and other phenomena appear, which in turn leads to poor welding quality of pipe fittings, thus increasing the scrap rate of pipe fittings, resulting in a certain waste of resources and increasing economic production costs
