AI Technical Summary

Technical Problem

Existing multi-diameter turning devices for automotive drive shafts can only fix drive shafts of a single diameter specification and cannot be adapted to cut drive shafts of different diameters.

Method used

A multi-diameter turning device for automotive drive shafts was designed, comprising a base plate, a fixed plate, an electric telescopic rod, a clamping ejector pin, and a cutting mechanism. The device achieves fixing and cutting of drive shafts of different diameters through adjustable support wedges and an electric telescopic rod, and uses a motor to drive the clamping ejector pin and rotating roller for fixing and cutting.

Benefits of technology

It enables the adaptation and fixed cutting of drive shafts with different diameter specifications, improving the flexibility and efficiency of drive shaft production and processing.
