Abstract
The tool change mechanism includes a tool storage magazine having a plurality of tool storage sockets disposed in two concentric circles. A tool transfer arm is mounted within the inner circle of sockets. The transfer arm may be rotated and extended or retracted and moved toward and away from the magazine for extracting a previously used tool from a ready socket and inserting such tool into a designated socket of the magazine. In like manner, the transfer arm will operate to extract a selected tool from any one of the sockets in the magazine and transfer it to the ready socket. The latter is mounted on a carrier which also supports a tool change arm. The carrier is pivotable between a loading position and a tool change position. When the carrier is in the loading position, the ready socket is located at the magazine where it is accessible to the tool transfer arm for extracting previously used tools from the ready socket and inserting new tools into it. On the other hand, when the carrier is in the tool change position it is located adjacent to the spindle in position to enable the tool change arm to interchange tools between the ready socket and the spindle.
