いない。Conventionally, machining centers have been used for two-spindle machine tools that automatically exchange cutters on two spindles simultaneously. Automatic tool change in this machining center is performed by an individual automatic tool changer (ATC) for each spindle. This method has the disadvantage of requiring two ATCs, resulting in high cost. Furthermore, in machine tools having three or more spindles, it is physically impossible to use Jin's method. A machining center with an automatic tool changer attached to a machine tool with three or more spindles has not yet been manufactured.
従って、多主軸を有する工作機械のカッタ交換は専ら手
作業とされていた。Therefore, changing the cutter of a machine tool with multiple spindles has been done exclusively by hand.

入した工具をクランプする手段が設けられである。Insertion and extraction of the shank portion of the tool into and out of the spindle hole of the spindle is performed by vertical movement of the spindle head (movement of the feed shaft). Further, the main shaft is provided with means for unclamping the tool to be extracted and for clamping the inserted tool.
とのATC及び主軸頭等の作動は、従来のATCにおけ
ると同様にNC手段によって制御される。The operation of the ATC and spindle head etc. is controlled by NC means as in the conventional ATC.
次に、左側主軸6に対する工具交換時の、とのATCの
作動を順序に従って説明する。Next, the operation of the ATC at the time of tool exchange for the left spindle 6 will be explained in order.

換は終了する。Next, the transport arm 13 moves forward and grips the tool mounted on the half shaft 6 with its grip 12. The cutter unclamping means installed at the top of the spindle is activated, and the tool is moved to the spindle 6.
After being unclamped against the tool, the spindle head 5 rises and the shank portion of the tool comes out. The transport arm 13 retreats,
Insert the tool into the pot at exchange position 10. The indexing device of the magazine means 2 is activated, and the bot 11 containing the tool of the designated tool number is indexed to the exchange position 10. the transport arm 13 grips the tool with its grip 12;
Carry it directly below the main shaft 6. The spindle head 5 is lowered and the shank of the tool is inserted into the spindle hole, after which the cutter unclamping means returns and the tool is clamped to the spindle. Thereafter, the transfer arm 13 retreats, and the automatic tool exchange for the main spindle 6 ends.
本発明の自動工具交換装置は以上の如く構成され、且つ
作動するので、多主軸工作機械に容易に取付けることが
でき、その構造も既存の方式を大部分流用することがで
