SINGLE POWER TOOL CHANGING DEVICE OF CNC MACHINING CENTER

摘要

A single power tool changing device of a CNC machining center includes a tool magazine unit, a cam-based tool changing unit, and a power clutch unit. The tool magazine unit includes a tool magazine body, a rotatable disk, and a plurality of tool sets. The cam-based tool changing unit includes a tool change base, a cam mechanism, and a tool changing mechanism. The power clutch unit includes a first force output axle that drives the tool magazine unit to operate, a second force output axle that drives the cam-based tool changing unit to operate, and a power mechanism, which selectively transmits power to the first or second force output axle. As such, the present invention allows for performance of both operations of tool selection and tool change with a single driving power source so as to achieve an advantage of reducing installation cost.
