Description

Technical Field

[0001] This invention relates to the field of spot welding machine technology, specifically a spot welding machine for motor manufacturing. 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, an instantaneous heat fusion is formed at the two contact resistance points.

[0003] Traditional spot welding machines can only move the welding torch up and down to facilitate the placement of the motor housing. However, this requires manual fixing and adjustment of the motor housing angle, which can lead to accidental burns before the welded point has cooled down. Therefore, it is necessary to design a spot welding machine for motor manufacturing that is highly practical and can automatically clamp the welding point. Summary of the Invention
