AI Technical Summary

Technical Problem

When changing cutting tools with different cutting edge thicknesses, existing technology can easily lead to tool breakage or flange damage, especially for hubless tools with thinner cutting edge thicknesses, which are difficult to install accurately.

Method used

A tool changing device is adopted, equipped with a thickness information acquisition unit (such as a camera unit or a measuring unit) to acquire the thickness information of the cutting tool. The installation position is adjusted by the holding part and the moving part to ensure proper contact between the cutting tool and the flange part and avoid excessive pressure.

Benefits of technology

It effectively prevents damage to cutting tools and flanges, ensures stable installation of cutting tools, and is suitable for replacing cutting tools with different cutting thicknesses.

Abstract

This invention provides a tool changing device that prevents breakage of cutting tools and damage to the flange when mounting cutting tools with different cutting thicknesses on a tool mounting base. The tool changing device used in a cutting apparatus includes: a holding part that detachably holds one side of the cutting tool; a moving part that moves the holding part, holding the cutting tool, relative to the spindle in the axial direction of the spindle, positioning the holding part at least at a mounting position where the other side of the cutting tool, located opposite to one side, is at least a predetermined distance from the flange of the tool mounting base, and at a disengaged position where the cutting tool is away from the tool mounting base; and a thickness information acquiring part that acquires information about the thickness of the cutting tool, adjusting the mounting position of the holding part based on the thickness of the cutting tool acquired by the thickness information acquiring part.
