Abstract

The present invention relates to a tool changing device that exchanges tools between a main shaft of working machine and a tool magazine, and to a working machine. The tool changing device includes an annular tool magazine provided with a plurality of grip arms supporting a tool holder. The tool magazine is supported by a column supporting a main shaft head provided with a main shaft movably up and down direction so as to enclose an outer circumference thereof. Since the barycentric position of the column in a state where the tool magazine is attached can be made closer to the barycentric position of the column in a state where the tool magazine is not attached, the tool changing device suppresses imbalance in the weight of the column and prevents deterioration in the accuracy of positioning control for the movement of the column.

Description

technical field [0001] The invention relates to a tool changing device and a machine tool for changing tools between a spindle of a machine tool and a tool magazine. Background technique [0002] The machine tool performs various processing such as milling and thread cutting with a single device according to the processing shape of the workpiece. The machine tool has a tool magazine and an ATC (tool changer) for holding multiple tools such as drills, end mills, and taps. The ATC automatically performs tool exchange between the tool magazine and the spindle (for example, refer to Japanese Patent Application Laid-Open No. 63-312038). [0003] In the conventional tool changer, the tool magazine is provided so that the tool magazine is adjacent to the base. The tool changer performs tool change by moving the column supporting the spindle head to a fixed position in the tool magazine. [0004] Since conventional machine tools required column movement, the time required for too...
