Abstract
A machine tool comprises a spindle and a tool changer for conveying tool holders between a magazine position and a working position at the spindle. The tool changer has two longitudinal rods and two transverse rods that are joined to said two longitudinal rods via universal joints so as to form an articulated rectangle. Each of said two longitudinal rods is rotatably mounted in the vicinity of its respective center. The tool changer comprises two grippers for gripping said tool holders to be conveyed. Said grippers are mounted on certain of said longitudinal and transverse rods such that upon rotation of the longitudinal rods the grippers are conveyed between said magazine position and working position while substantially maintaining said tool holders in their preferably vertical orientation.
