Welding device with automatic material changing function and welding method thereof

Abstract

The invention discloses a welding device with the automatic material changing function and a welding method thereof. A feeding part is eccentrically and rotatably connected to a storage part, outlets of feeding pipelines can alternately correspond to a to-be-welded area on a base metal plate, and pushing parts sequentially correspond to a material receiving area and inlets of the feeding pipelines in the moving direction of the pushing parts. According to the eccentric and rotatable arrangement of the feeding part, the material receiving area can correspond to different storage pipelines to the receive the material, the pushing parts sequentially correspond to the material receiving area and the inlets of the feeding pipelines in the moving direction of the pushing parts, and in the rotating process of the feeding part, the pushing parts can sequentially push the to-be-welded objects in the material receiving area to enter the inlets of the feeding pipelines; therefore, after the material receiving of the material receiving area and the position of the feeding pipeline relative to the to-be-welded area are switched, the pushing parts can push different to-be-welded objects on the material receiving area to enter the corresponding material receiving pipelines, the situation that in the welding process of the various to-be-welded objects, the conveying pipelines corresponding to the different to-be-welded objects are controlled to move is not needed, and the to-be-welded objects can be quickly switched.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an automatic refueling welding device and a welding method thereof. Background technique [0002] Conventional resistance welding is generally suitable for thin plate welding. High-strength steel plates are often used for the back door of special vehicles and the thickness of the plate exceeds 5mm. There is a technical bottleneck in ordinary resistance welding. Manual welding is inefficient, the welding effect is easily affected by the environment, and the welding accuracy is poor in consistency. The utilization rate of robot welding equipment is not high, the one-time investment is expensive, the maintenance cost of equipment is high, and the requirements for operators and programmers are high. Portable tube-sheet welding equipment requires a lot of adjustment work, and the portable is mainly operated by people. The large amount of adjustment here refers to human control, whic...
