Description

Quick dismounting tool for welding gun electrode assembly

Technical Field

The utility model relates to the technical field of vehicle body welding and manufacturing, in particular to a rapid dismounting tool for a welding gun electrode assembly.

Background

Spot welding refers to a welding method in which a welding spot is formed between two overlapping workpiece contact surfaces by using an electrode rod during welding. After the welding parts are combined, pressure is applied through the electrodes, then current is conducted, and resistance heat generated by the current passing through the contact surface and the adjacent area of the electrode cap is utilized for welding. Because the welding is completed in a short time, a great current and pressure are required to be applied, and the electrode rod is often worn and leaked in the process of replacing the electrode cap, the electrode assembly (comprising the electrode rod, the electrode rod seat, the conductive block and the like) can generate conical surface deformation and metal corrosion phenomena, so that the electrode assembly is extremely difficult to disassemble. The common way is to clamp the electrode assembly using a pipe wrench, and the worker forcibly rotates while pounding the electrode using a hammer. However, this approach is labor intensive, and the common tool is not able to hold the electrode assembly while providing sufficient axial tension to remove the electrode assembly, and eventually wastes a lot of time, and the electrode assembly cannot be removed, and only the entire electrode arm can be replaced.

The electrode fixing member 120 is movably connected to the dismounting end 110a of the connecting member 110, the connecting end 110b of the connecting member 110 is connected to the fixed end 200a of the operating rod 200, the limiting end 200b of the operating rod 200 is provided with a limiting seat 400, the counterweight 300 is movably sleeved on the operating rod 200, and the counterweight 300 can set weight according to actual requirements.

In use, the connector 110 is first connected to the electrode assembly to connect the electrode assembly to the gun electrode assembly quick disconnect 10 of the present utility model. In order to improve efficiency, for example, the welding gun electrode assembly quick release tool 10 of the present utility model is arranged such that the extraction direction of the electrode assembly is perpendicular to the ground, the operating weight 300 slides radially on the operating lever 200, and the weight 300 exerts a force radially toward the ground, providing a radial pulling force for removing the electrode assembly. The counterweight 300 continuously and cyclically impacts the stopper 400 until the electrode assembly is successfully disassembled.

The electrode fixing member 120 includes a fixing pin, and the detachable end 110a of the connection member 110 includes a connection hole 111, and the fixing pin is connected in the connection hole 111.
