In order to ensure the machining accuracy and stability of copper bushings, especially in complex machining processes, how to effectively support and fix the copper bushings is a key issue.

[0003] Traditional copper sleeve processing tooling mostly uses a simple support structure, usually composed of a fixed fixture or a basic support device. These tooling has certain shortcomings in practical applications, such as being unable to meet the adjustment requirements of different processing heights, the support point fixation is not stable enough, and may cause the copper sleeve to shift or deform during the processing process. Especially when processing precision or thin-walled copper sleeves, the shortcomings of traditional tooling are more obvious. These problems not only affect the processing accuracy, but may also lead to low production efficiency and unstable processing quality, which in turn affects the performance and reliability of the final product.

By achieving height adjustment of the tooling, providing stable internal and external support, and adopting advanced electric drive systems and transmission mechanisms, this tooling can significantly improve the processing accuracy and stability of copper sleeves and meet the high requirements of modern precision machining.
