The rotating disc type automatic flame welding machine comprises a machine body, the machinebody is provided with a welding frame, a rotating disc is arranged at the top of the welding frame, a driving assembly is arranged at the bottom of the welding frame and drives the rotating disc to rotate, a feeding device is arranged on one side, located on the rotating disc, of the welding frame, a welding device is arranged on the other side of the welding frame, clamping devices are evenly arranged at positions, corresponding to the feeding device and the welding device, of the rotating disc, each clamping device is provided with a clamping frame, a high-speed precise cam divider is arranged at the top of each clamping frame, each high-speed precise cam divider is rotationally connected with a clamping table, each high-speed precise cam divider controls the corresponding clamping tableto rotate intermittently, an a clamping assembly is arranged on one side, away from the circle center of the rotating disc, of each clamping table and used for fixing a workpiece; and the welding method comprises the following steps of a, preparing before welding; b, feeding; c, welding; and d cyclic batch processing. According to the rotating disc type automatic flame welding machine and the welding method thereof, the welding precision of the workpiece is improved, and meanwhile the phenomena of insufficient welding and missing welding are eliminated.

Description

Technical field [0001] The invention belongs to the technical field of welding equipment, and specifically relates to a turntable type automatic flame welding machine and a welding method thereof. Background technique [0002] Welding, also known as welding or welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Different metals and workpieces with different structures require corresponding welding processes and equipment to implement welding. As a traditional manufacturing process and technology, welding technology has developed rapidly in industrial applications in recent years. Welding can be divided into manual welding, semi-automatic welding, and automatic welding according to the degree of automation; among them, manual welding is to manually hold the welding torch for welding; semi-automatic welding usually refers to the fixed welding torch, the workpiece is r...

AI Technical Summary

Problems solved by technology

[0003] When welding the connecting pipe, at least two joints between the connecting pipe and the joint need to be welded. Due to the irregularity of the pipe and the existence of multiple welding points, when welding with an automatic flame welding machine, there is a phenomenon that the clamping is not stable, and when welding During the process, the position of the welding torch and the wire feeding gun needs to be constantly adjusted for multiple welding points, resulting in cumbersome operation, long welding time, and the welding accuracy cannot be guaranteed, and there are phenomena of false welding and missing welding
