AI Technical Summary
In the existing technology, steel wheel hubs suffer from insufficient positioning accuracy and poor stability during cutting and processing. In particular, when placed vertically, they are prone to movement and offset, which affects processing efficiency and accuracy.
The system employs a combination of fixed columns and positioning units. The positioning columns are inserted into the center hole of the steel rim hub, and multiple sets of positioning columns are opened and pressed using a limiting mechanism and pneumatic components. Combined with auxiliary mechanisms, it provides further positioning and support, ensuring the stability and accuracy of the steel rim hub during the cutting process.
This effectively avoids loosening, displacement, and shaking of the steel rim hub during the cutting process, improves processing stability and precision, and ensures the reliability and accuracy of cutting the raw materials for the steel rim hub.
