Claims

[Scope of utility model registration request]

For a machine tool that processes a workpiece by moving a spindle with a tool attached to its tip forward and backward along this axis and rotating, the spindle is normally moved back to a position far away from the axis of the spindle, and when changing tools, the spindle is A reciprocating mechanism is provided that moves forward to a position approaching the axis of the main spindle when the tool retreats from the processing position of the workpiece with the used tool, and a pair of tool gripping mechanisms is provided at the tip of the retracting mechanism, One of the empty gripping mechanisms grabs the used tool at the tip of the spindle as the advancing/retracting mechanism moves forward;
A tool changing device for a machine tool, characterized in that, in this state, the position of the other gripping mechanism that has previously gripped the replacement tool is switched, and the replacement tool is attached to the tip of the spindle.
