AI Technical Summary
In the existing technology, the clamps of the ventilation channel steel cannot provide sufficient downward pressure, which leads to unstable spot welding of the ventilation channel plate and may result in collapse or crushing.
A spot welding device for motor ventilation slot plates was designed, comprising a clamping block, a pressing clamping block, and an operation button. By rotating the clamping block and cooperating with the pressing clamping block, the ventilation slot plate is stably limited, ensuring the stability of the spot welding process.
This improved the spot welding stability of the ventilation slot plate, avoided collapse or crushing caused by insufficient clamping, and ensured welding quality.
