AI Technical Summary
In the existing technology, the small-batch production of self-locking nuts for floating pallets requires expensive special finishing equipment, resulting in high unit cost of the product.
A self-locking nut closing fixture for a floating support plate was designed, including a lower fixture and an upper fixture. The closing accuracy is ensured by the cooperation of the guide protrusion and the guide groove, and the closing amount is controlled by adjusting the stroke through the washer. The unloading hole simplifies the part removal process.
This invention achieves a simple and easy-to-operate self-locking nut end capping mechanism, reducing equipment modification costs, improving production efficiency, and preventing damage to the nut surface.
