Description

Technical Field

[0001] The utility model relates to the technical field of welding gun positioning, in particular to a welding gun positioning device. Background Art

[0002] With the development of the power and sheet metal machinery industries, energy storage welding screws are increasingly widely used in various sheet metal structures. When using an energy storage welding gun to weld screws, marking and punching are often used to locate the welding position: manual marking positioning has large deviations; punching positioning will affect the welding strength (the principle of energy storage welding is that the capacitor discharges energy to melt the bottom of the welding screw so that it is welded to the parent material. If the plate is uneven, it will affect the bottom welding). In severe cases, it will cause the welding screw to be cold welded or fall off, posing a safety hazard;

[0003] Traditional energy storage welding guns have some shortcomings. Traditional energy storage welding guns only have three fulcrums to ensure the verticality of the screws and the plate, but there is no positioning structure. How to solve the positioning problem of the energy storage welding gun is the key to improving the welding quality of the product. Utility Model Content
