Novel tube plate automatic welding machine tool

Abstract

The invention provides a novel tube plate automatic welding machine tool which comprises a tube plate welding machine assembly, and the tube plate welding machine assembly comprises a rotary welding machine assembly. The rotary welding machine assembly comprises a positioning pipe and a welding gun adjusting assembly rotating along the circumference of the positioning pipe. The welding gun adjusting assembly is in transmission connection with the welding gun, and the welding gun adjusting assembly can adjust the working position between the welding gun and the positioning pipe. The rotary workbench comprises a rotary positioning disc and a rotary disc driving assembly in transmission connection with the rotary positioning disc. The rotary positioning disc comprises a rotary disc body, a plurality of pipe holes are formed in the plate face of the rotary disc body, and automatic pipe clamps are arranged on the bottom face of the rotary disc body and correspond to the pipe holes. The outer side of the circumference of the rotating disc body is provided with a positioning groove and a positioning and pressing assembly arranged in the positioning groove, and the positioning and pressing assembly can move inwards or outwards in the radial direction of the rotating disc body. The pipe plate automatic welding machine tool is high in automation degree, and high-quality welding of the pipe plate and the pipe fitting can be conveniently, rapidly and efficiently achieved.

Description

technical field [0001] The invention relates to the technical field of welding machines, in particular to a new type of tooling for an automatic welding machine for tube sheets. Background technique [0002] In the welding process of several pipe fittings of the heat exchanger and the tube sheet, it is particularly important to use a welding torch that can rotate along the circumference of the fixed column to improve the welding efficiency of the tube sheet. However, most of the existing devices suitable for tube sheet welding are only improved by rotary welding torches. During the welding process of tube sheet and pipe fittings, manual or simple fixtures are used to fix the tube sheet and welded pipe fittings. After each pipe fitting is welded, it is necessary to re-align The other pipe fitting is positioned and clamped with the tube sheet, and the welding efficiency of the tube sheet is low; and this type of rotary welding torch has higher technical requirements for the we...

Problems solved by technology

However, most of the existing tube-sheet welding devices are only improved on the rotary welding torch. During the welding process of the tube-sheet and pipe fittings, the tube-sheet and the welded pipe fittings are fixed manually or with simple clamps. After each pipe fitting is welded, it needs to be re-aligned. Another pipe fitting and tube sheet are positioned and clamped, and the welding efficiency of the tube sheet is low; and this type of rotary welding torch has high technical requirements for the welding operator during the welding process of the tube sheet and the pipe fitting, otherwise it will easily lead to the welding of the pipe fitting and the tube sheet. Incomplete, reducing weld quality
