AI Technical Summary

Technical Problem

Existing automotive longitudinal beam grinding processes are inefficient, cannot achieve full automation and simultaneous grinding of multiple surfaces, and are not suitable for production lines.

Method used

Design a three-sided grinding device for longitudinal beams, including grinding mechanisms for the top, bottom and side surfaces of the longitudinal beams, as well as a floating friction roller mechanism. The device drives the longitudinal beam workpieces to move through friction, and works in conjunction with multiple grinding mechanisms to achieve simultaneous grinding of multiple surfaces of multiple longitudinal beam workpieces.

Benefits of technology

It improves the efficiency of longitudinal beam grinding, is suitable for production lines, and enables simultaneous grinding of multiple surfaces of longitudinal beam workpieces, reducing the need for manual adjustments.
