Description

Technical Field

[0001] This utility model relates to the field of welding machines, specifically a workpiece position adjustment device for welding machines. Background Technology

[0002] A spot welding machine is a mechanical device that uses the principle of double-sided, double-point overcurrent welding. During operation, two electrodes press the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes. When the welding current flows from one electrode to the other electrode, it forms an instantaneous thermal fusion at the two contact resistance points. The welding current also flows instantaneously from the other electrode along the two workpieces to this electrode to form a circuit, without damaging the internal structure of the workpiece being welded.

[0003] For example, patent CN220492577U discloses an anti-splatter spot welding machine, which relates to the field of spot welding machine technology. It includes a main body, a support platform fixedly installed on the side of the main body, a cylinder fixedly installed on the upper end of the main body, a spot welding head fixedly installed at the output end of the cylinder, a lower electrode fixedly connected to the upper end of the support platform, a guide rail fixedly connected to the side of the support platform, a movable block slidably connected to the surface of the guide rail, and a rotating shaft fixedly installed at the upper end of the movable block. Using the rotating shaft, a connecting plate can be sleeved on the outside of the rotating shaft and rotated around the rotating shaft.

[0004] The aforementioned patent's bracket can support the workpiece to be spot welded, allowing users to correctly position and place the workpiece into the bracket. The bracket then carries the workpiece between the spot welding head and the lower electrode, preventing misalignment and avoiding impact on overall processing time. Furthermore, the use of multiple brackets allows the spot welding machine to process multiple workpieces simultaneously, improving welding efficiency. However, the aforementioned patent has a drawback: the welding machine can only weld one position on a workpiece at a time, and this position is fixed and cannot be adjusted. Generally, larger workpieces have multiple weld points, and the fixed support structure of the aforementioned welding machine cannot meet these requirements.

[0005] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content
