Electrode clamping welding mechanism

Abstract

The invention relates to an electrode clamping welding mechanism. The electrode clamping welding mechanism comprises a clamping welding mechanism arranged on a rack and a positioning mechanism capableof clamping a workpiece, wherein the positioning mechanism corresponds to the clamping welding mechanism, the clamping welding mechanism comprises at least one pair of lower electrode holder and upper electrode holder arranged on the rack and capable of being opened and closed oppositely; a welding groove is formed in the lower electrode holder, and at least one lower electrode is arranged in thewelding groove; a classified displacement mechanism is arranged on the rack and is in drive connection with the upper electrode holder arranged on the rack in a sliding manner, and an upper electrodecapable of performing classified press-fit displacement relative to the lower electrode is arranged in the upper electrode holder; and a press-down mechanism and a lifting device which can realize flexible press-fit and separation are arranged in the classified displacement mechanism, and an elastic press-fit damping part is arranged in the press-down mechanism. The electrode clamping welding mechanism capable of realizing flexible clamping welding of the lap joint position of the workpiece and a cable is provided.

Description

technical field [0001] The invention relates to the field of mechanical processing, mainly to the field of workpiece welding, and in particular to an electrode clamp welding mechanism. Background technique [0002] Existing patent: A purple light tube electrode welding device and its welding method (patent number: 201810750327.9), which discloses a purple light tube electrode welding device and its welding method, involving the field of ultraviolet photoelectric tube manufacturing technology, including the upper base and the lower base , There is a guide column between the upper base and the lower base, an upper mold is installed at the bottom of the upper base, cathode limiting slots are provided on both sides of the upper mold, and anode limiting slots for anodes are placed at the bottom of the upper mold.

Problems solved by technology

[0003] In the prior art, although fixed-point welding can be performed on workpieces, the welding press-fit structure exerts force directly on the welded part of the workpiece through mechanical stress. When there is no damping force for pressing down, it is easy to cause excessive force during press-fit welding, resulting in Mechanical damage to the welding part of the workpiece, and it cannot be quickly returned to its position during recovery, and at the same time it cannot be conveniently and effectively welded to the workpiece to be welded in the adjacent welding tank
