Abstract

The invention provides an electrode holder with convertible movable electrode and fixed electrode. The electrode holder comprises a welding machine, a gear, an upper electrode assembly and a lower electrode assembly, wherein the welding machine is installed above the gear; the upper electrode assembly and the lower electrode assembly are installed below the gear; the welding machine is connected with the upper electrode assembly, the lower electrode assembly and the gear separately; the upper electrode assembly and the lower electrode assembly are separately installed below the gear; the upper electrode assembly comprises a first driving device, a connecting rod mechanism, an upper electrode air cylinder moving unit, an upper electrode flexible connecting plate, an upper electrode plate, an upper electrode, a double-linear-sliding-rail mechanism, an upper motor conducting transition plate and an upper electrode conducting transition plate, wherein one end of the upper electrode air cylinder moving unit is connected with the first drive device, and the other end of the upper electrode air cylinder moving unit is movably connected with the connecting rod mechanism; and the connecting rod mechanism is connected with the upper electrode plate and the double-linear-sliding-rail mechanism separately. The electrode holder has the beneficial effects that: 1, the welding automation level of the area is improved; and 2, the welding spot consistency output is improved, and the welding quality is ensured;.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a welding tongs with switchable moving and static electrodes. Background technique [0002] In the welding area of ​​door cover and window frame, the current automatic welding method is robot welding tongs welding, or gantry automatic welding. However, the distance between the inner and outer plates is small, and two welding tongs are required to complete the welding of the solder spots on the inner and outer plates, such as figure 1 Shown: Welding the solder joints in area A requires the moving electrode to be on top and the static electrode to be on the bottom. Welding the solder joints in area B requires the moving electrode to be on the bottom and the static electrode to be on top. The static and dynamic electrodes of the existing welding tongs equipment cannot be converted, changed, or compatible. It is necessary to add welding tongs equipment or workstations to rea...
