つている。 In machine tools equipped with automatic tool changers,
It is known that a rotating body supporting a tool exchange arm is provided so as to be rotatable between the tool magazine side and the spindle head side, and the spindle tool is exchanged at the retreating end of a column on which the spindle head is mounted. In this conventionally known system, in order to avoid interference between the column and the revolving body, the column first retreats to the retreat end in response to a tool change command, and upon confirmation of the retreat end, the revolving body rotates toward the spindle head side. In this state, tools are exchanged using the exchange arm, and this operation lengthens the tool exchange time.

て次回の工具交換まで待機するのである。 In response to the tool exchange command, the column 2 moves backward to the backward end. During this time, the spindle head 3 moves up and down to position the spindle 8 at a predetermined position for tool exchange. Simultaneously with the retreat of this column, the synchronizing cylinder 14 moves backward, whereby the engaging member 16 engages with the engaging roller 12, overcoming the fluid pressure of the return cylinder 18 and moving the rotating body 6 toward the shaft head 3. Turn to A. In this state, the exchange arm 7 rotates and moves back and forth to exchange the spindle tool, then the synchronization cylinder 14 is advanced and the column 2 is advanced to the machining position, and the return cylinder 18 moves the rotating body 6 into the tool magazine 5.
The tool is rotated to side B, the old tool is put back in, the new tool is taken out, and it waits until the next tool change.
尚、工具交換指令時のコラム２の位置に応じて
旋回体６の旋回には次の３形態がある。 Note that there are the following three types of rotation of the rotating body 6 depending on the position of the column 2 at the time of the tool exchange command.

る利点を有している。 As described above, in the present invention, when the column moves backward for tool exchange, the synchronizing member provided on the column engages with the engaging member of the rotating body, and the rotating body moves the spindle head in synchronization with the backward movement of the column. Since the structure is such that the column can be rotated to the side, the rotating body can be rotated toward the spindle head side as soon as the column reaches the retreating end. This allows tools to be changed by the exchange arm immediately at the column's retreating end position. This has the advantage that there is no waste in the operation, and tool exchange time can be shortened.
