AI Technical Summary

Technical Problem

Existing floating tool chucks can only float horizontally during tool changing, making it difficult to accurately identify whether the tool is precisely inserted into the mounting position, leading to problems such as unsuccessful tool changing or tool damage.

Method used

A floating tool chuck structure was designed, comprising a base, a Z-axis floating unit, a horizontal floating module, and a position switch. It has a vertical floating buffer function and achieves precise tool alignment and installation through the cooperation of the Z-axis floating unit and the horizontal floating module.

Benefits of technology

It achieves accurate identification and proper installation of cutting tools, avoiding problems such as unsuccessful tool changes or tool damage, and ensuring smooth tool changes.

Abstract

This invention discloses a floating tool chuck structure and an automatic tool changing method. The floating tool chuck structure includes a base connected to the end effector of a robotic arm, moving together with the end effector; a Z-axis floating unit connected to the base; a horizontal floating module including a fixed unit and a floating block connected to each other, the fixed unit being connected to the Z-axis floating unit so that the horizontal floating module floats vertically together with the Z-axis floating unit; a pair of chucks connected to the floating block of the horizontal floating module, achieving horizontal floating under the adjustment of the horizontal floating module; and a positioning switch set on the stroke of the Z-axis floating unit, triggering a positioning signal based on the displacement of the Z-axis floating unit in the vertical direction. By adopting the structure and method of this invention, the tool installation position can be accurately identified, and vertical floating buffering can be achieved after the tool is installed, effectively protecting the machine tool and the tool, and facilitating smooth tool changing.
