Welding device of a fully automatic welding machine

Abstract

The invention relates to the field of welding equipment, in particular to a welding device of a fully-automatic welding machine. The welding device comprises a jacking device used for fixing welding fittings, a welding mechanism used for welding materials and the fittings and a second rotating device used for driving placing rods to rotate. A circular rotating disc is arranged on the near side of the second rotating device. The multiple placing rods used for being provided with the materials in a sleeved mode are arranged on the edge of the top of the rotating disc. All the placing rods are arranged in the circumferential direction of the rotating disc in an angular difference mode. The welding mechanism is arranged over the placing rods. The second rotating device is arranged on the near sides of the bottom ends of the placing rods. A jacking air cylinder is arranged at the position, over the placing rods close to welding device, of the jacking device. The output end of the jacking air cylinder faces vertically downward. The bottom of the jacking cylinder is provided with a bearing plate used for bearing the jacking air cylinder. A through hole used for allowing the output end of the jacking air cylinder to penetrate through is formed in the bearing plate. The tubular materials are welded by adopting a double stroke welding mode, the welding efficiency is improved, and it is ensured that welding of the periphery of a pipeline is closed completely.

Description

technical field [0001] The invention relates to the field of welding equipment, in particular to a welding device of a fully automatic welding machine. Background technique [0002] The automatic welding machine is composed of mechanical device, power supply device and control device. In order to meet the welding process requirements, the pressurizing mechanism adopts a double-stroke fast pneumatic transmission mechanism. The normal state is that the welding tongs are opened in a short stroke. When the control button is switched To the "power on" position, pull the handle switch to clamp and pressurize the welding tongs. At the same time, the current returns to the short-stroke open state after completing a welding cycle under the control of the control system. The welding tongs generally weld high-strength steel plates and low-carbon steel sheets. , the welding method for tubular materials is not a double-stroke welding method, the welding efficiency is low, and it is diffi...
