Full-automatic flange welding machine

Abstract

The invention provides a full-automatic flange welding machine. The machine comprises a progressive feeding mechanism, an automatic aligning and positioning mechanism mounted in front of the progressive feeding mechanism, a discharging platform arranged in front of the automatic aligning and positioning mechanism, a linear guide rail mounted on one side of the automatic aligning and positioning mechanism, a feeding grabbing mechanism, a discharging grabbing mechanism and a welding gun which is mounted on one side of the automatic aligning and positioning mechanism and directly faces the linear guide rail; one end of the linear guide rail extends to the middle of the progressive feeding mechanism, the other end of the linear guide rail extends to the back end of the discharging platform; and the feeding grabbing mechanism and the discharging grabbing mechanism are mounted on the linear guide rail side by side. With the machine, automatic feeding, positioning, welding and discharging of flanges can be realized through cooperation of the progressive feeding mechanism, the feeding grabbing mechanism, the automatic aligning and positioning mechanism and the discharging grabbing mechanism, double-surface welding of the flanges can be completed at a time, priming and covering are not required, and the flange welding efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a fully automatic flange welding machine. Background technique [0002] At present, most of the flanges are welded manually, the speed is slow, and the welding effect depends on the experience of the welder, and the quality is uneven. A space curve-intersecting line (also known as a saddle curve) will be formed at the intersection of the flange fractures. ), this welding joint is deep and long due to the large wall thickness of the component, and the primary welding joint is deep and long. Usually, it needs to cover the bottom and cover the surface, and multiple layers and multiple fillings are required in the middle to complete it; especially the welding seam is a space During the welding process, the welding torch must walk along the space trajectory and continuously adjust the posture in sections, which makes welding very difficult. At the same time, the automatic positioning...

Problems solved by technology

[0002] At present, most of the flanges are welded manually, the speed is slow, and the welding effect depends on the experience of the welder, and the quality is uneven. A space curve-intersecting line (also known as a saddle curve) will be formed at the intersection of the flange fractures. ), this welding joint is deep and long due to the large wall thickness of the component, and the primary welding joint is deep and long. Usually, it needs to cover the bottom and cover the surface, and multiple layers and multiple fillings are required in the middle to complete it; especially the welding seam is a space During the welding process, the welding torch must walk along the space trajectory and continuously adjust the posture in sections, which makes welding very difficult. At the same time, the automatic positioning and fixing of the flange fracture weld seam is an important factor affecting the welding quality of the flange. When welding, the welder needs to manually align and fix it with a pressing block before welding, and only one end face can be welded at a time. After completion, it needs to be turned over 180 degrees and fixed again to weld the other side

Manual welding has a long manufacturing cycle, high labor intensity, low production efficiency and difficult to guarantee welding quality, and it is impossible to realize automated mass production
