AI Technical Summary

Technical Problem

During the process of processing V12 crankshaft of Gamma2000 turning and milling composite machine tool, the existing top-end devices are cumbersome to install and disassemble, resulting in low machining efficiency, and the butt structure between the top-end core and the spindle is complex, which affects the machining accuracy. At the same time, the remaining iron filings on the top are difficult to effectively clean up, affecting the accuracy of the product.

Method used

A top-notch device is designed, including a top-notch body, a top-notch core and a top-notch storage sleeve. The top core is installed in conjunction with the Mohs cone hole of the top body through the Mohs cone section, achieving simple and convenient installation and replacement. The top storage sleeve has built-in inner cooling tube, which blows away the iron filings on the top through high-pressure cold liquid.

Benefits of technology

This device makes top-notch installation and disassembly more convenient, ensures processing accuracy, and improves processing efficiency and product quality through efficient iron filing cleaning.
