Automatic welding device

Abstract

The invention provides an automatic welding device, which can be used for machining metal jewelries and comprises a worktable; the worktable is provided with a tool clamp device loaded with multiple parts to be welded and machined and capable of being fast disassembled and replaced; a movable welding gun assembly capable of moving according to the arraying mode of the machining parts to be welded is arranged above the tool clamp devices; a part corresponding to the movable welding gun assembly is provided with a two-degree-of-freedom welding table module; and the two-degree-of-freedom welding table module is provided with a welding needle matched with the movable welding gun assembly. The automatic welding device overcomes the defects of low efficiency and poor welding quality in metal welding machining of the prior art, fast positioning and continuous automatic welding in the metal welding process can be realized based on the butt-welding in the electric resistance welding, the welding precision and welding quality are effectively ensured, the welding standardization is facilitated, the cost is reduced, the efficiency is improved, the work environment of workers is improved, and the finishing of the automatic welding also provides technical support for realizing the automation of metal jewelries machining production lines.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an automatic welding device used in metal processing and maintenance. Background technique [0002] Welding is an important process in metal processing, especially in precious metal jewelry processing. It is mainly used to solve problems such as making jewelry metal molds, connecting jewelry parts, jewelry inlays, jewelry molds, and jewelry maintenance. , Modeling, maintenance and other links essential technology. However, due to the complex physical and chemical process of welding, which integrates knowledge of electricity, heat, and materials, and is a change of instantaneous local high temperature, it is difficult to evaluate and there is no unified standard. Therefore, the welding process directly affects the firmness of the connection of the components, the firmness of the inlaid gemstones, the completion of the follow-up process, the realization of the jewelry design and ...
