Abstract
The utility model discloses an electrode structure for the welding of a resistance pin. The electrode structure comprises an electrode holding portion and an electrode welding portion, the electrode welding portion is inserted in the electrode holding portion, and a U-shaped groove arranged along the electrode welding portion in the radial direction is opened at the bottom of the electrode welding portion. The electrode structure for the welding of the resistance pin has the advantages of being stable in performance during welding, consistent in solder joint appearance, convenient for resistor pin to lap and connect during welding and high in welding efficiency.
Description
Technical field
The utility model relates to a kind of electrode structure for the welding of resistance pin, belongs to field of welding devices.
Background technology
At present, use resistance pin welding electrode to comprise upper and lower electrode.Generally, upper and lower electrode structure is consistent, during electric welding machine work, upper/lower electrode docking, existing electrode end surface is generally plane, resistance pin overlap joint difficulty during operation, welding efficiency is low, aspect material, electrode generally adopts the materials such as chromium zirconium copper, beryllium-bronze class, easily produces fried weldering phenomenon in welding process, electrode is fragile, electrode adopts integral structure more, after electrode is damaged, needs integral replacing, and electrode material is caused to great waste.
Summary of the invention
Technical problem to be solved in the utility model is the defect that overcomes prior art, and a kind of electrode structure for the welding of resistance pin is provided, stable performance during its welding, and solder joint outward appearance is consistent, and while making to weld, resistance pin overlap joint is convenient, and welding efficiency is high.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of electrode structure for the welding of resistance pin, comprise electrode clamping part and electrode welding portion, electrode welding portion is inserted on electrode clamping part, and described electrode welding Bu bottom has the U-shaped groove of radially arranging along electrode welding portion.
Further, the bottom of electrode clamping part has blind hole, and described electrode welding Bu top is interference fitted in the blind hole of electrode clamping part.
Further, electrode clamping part is made by brass material.
Further, electrode welding portion is made by pure tungsten material.
Adopted after technique scheme, electrode clamping part of the present utility model is connected with electrode welder arm, and adopts two parts to form, need to be when electrode damage integral replacing, U-shaped groove is for fixed resistance pin welding, while making to weld, resistance pin overlap joint is convenient, and this electrode can be applicable to general point welding machine, without welding machine special, can realize, use versatility is high, welding performance is stable, and solder joint outward appearance is consistent, and has improved welding efficiency.
