Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling, and more specifically, to a spot welding device. Background Art

[0002] Spot welding is a welding process that uses electrode pressure to clamp the workpieces together and releases a large current through both ends of the electrode to melt the contact surface between the workpiece and the electrode to form a weld nugget to achieve the welding purpose.

Currently, the wound electromagnetic coil is placed under the spot welding machine manually, the lead terminal is placed on the lower electrode head, and the lead terminal is then stamped and spot welded by the upper electrode head, so that one end of the coil is welded to one end of the lead terminal. Then the electromagnetic coil is moved and the coil end at the other end is spot welded to the lead terminal. Due to the small size of the lead terminal, manual alignment is difficult and welding position deviation is likely to occur, affecting the welding effect. Therefore, improvement is urgently needed.
