Automatic scaffold welding machine and welding method thereof

Abstract

The invention provides an automatic scaffold welding machine. The welding machine is used for automatic welding of a main steel pipe serving as a vertical rod in a steel pipe scaffold with socket andspigot joints and a socket pipe and an U-shaped socket part. The welding machine comprises a base, the front side of the base is provided with a three-shaft position-changing device for switching a feeding station with a workpiece to be welded and a welding station and realizing rapid welding of the two surfaces of the workpiece to be welded through 180-degree-rotation of the welding station; twogantry type welding gun supports which are vertically arranged are installed on the two sides of the rear side of the base, a cross frame beam is arranged between the two welding gun supports, and thecross frame beam is provided with a spot welding mechanism which is used for carrying out spot welding on the socket pipe which is at the welding station of the three-shaft position-changing device and fixed on the main steel pipe and a multiple sets of double-gun welding mechanisms which are used for simultaneously welding weld joints of all U-shaped socket parts; and one end of the cross framebeam is provided with a welding gun walking mechanism which is used for pulling the multiple sets of double-gun welding mechanisms to move at the same time to carry out welding on the welding joints of all the U-shaped socket parts correspondingly. The invention further provides a welding method of the automatic scaffold welding machine.

Description

【Technical field】 [0001] The invention relates to automatic welding equipment, in particular to an automatic scaffold welding machine and a welding method thereof. 【Background technique】 [0002] Scaffolding is an essential operating facility in the construction industry. Existing scaffolds are usually composed of metal pipes and metal fasteners. Lap the metal pipes in a criss-cross pattern and fix them with metal fasteners at their intersections. The structural differences of existing scaffolds are mainly reflected in the metal fasteners, and the use of metal fasteners with different structures leads to a gap in the connection mode and stability of the metal pipes. The disadvantage of this kind of fastener scaffolding is that the construction progress is slow, the labor intensity of the workers is high, it is not easy to install and disassemble, and there are many parts of the scaffold, which is not conducive to storage and transportation; on the other hand, metal fastene...

Problems solved by technology

[0005] Aiming at the low production efficiency of the existing socket-type steel pipe scaffolding pole welding, the present invention provides a method that adopts 17 welding torches to weld at the same time, and effectively realizes the automatic exchange and transformation of the welding workpiece between the feeding station and the welding station. Automatic welding machine for scaffolding, which realizes fast welding on both sides of the welding workpiece and convenient replacement of loading and unloading materials, easy operation and maintenance, greatly reduces the cost of equipment, improves welding quality and production efficiency, and effectively reduces labor intensity. and its welding method
