At the top of the column 1, a tool magazine 3 is horizontally disposed with its upper and lower surfaces supported by guide rails 4, and this tool magazine is driven by an endless chain 6 driven by a magazine drive motor 5. Then, it is rotated one pitch at a time. The tool magazine 3 is provided with a large number of tool pots 7, and each tool pot 7 holds a tool T such as a drill.
A mounting hole 7a is formed therein. Reference numeral 8 denotes a headstock which is supported movably in the vertical direction by the guide surface 2 at the lower part of the column 1, and on this headstock 8, a main shaft 9 extending in a direction perpendicular to the column 1 is rotatably supported. A mounting hole 9a for the tool T is provided at one end of the main shaft 9.

を終了する。 First, after performing work with the tool T 1 attached to the tip of the spindle 9, when it becomes necessary to replace the tool T 1 , the tool T 1 to be replaced is located at a position directly above the spindle 9. The tool magazine 3 is driven. Then, when the feed screw 22 is driven by the headstock drive motor 21 and the headstock 8 is moved upward, the top surface of the headstock 8 is aligned with the exchange arm mounting base 1.
0, and this mount 10 moves upward together with the headstock 8. When the upper surface of the mount 10 comes into contact with the lower surface of the guide rail 4 of the tool magazine 3, the movement of the mount 10 and the headstock 8 is stopped. Here, the tool T 1 of the spindle 9 and the tool magazine 3 are connected by the tool gripping claw 16 of the exchange arm 15.
and tool T 2 at the same time. Then, the exchange arm 15 is moved forward (to the left in FIG. 2) by the reciprocating cylinder 14 of the mount 10, the tools T 1 and T 2 are extracted from the spindle 9 and the tool magazine 3, and the worm gear provided on the mount 10 is removed. 13, the exchange arm 15 is rotated 180 degrees, and the tools T 1 and T 2 are rotated up and down. Thereafter, the exchange arm 15 is moved backward (to the right in FIG. 2) by the reciprocating cylinder 14, and the tools T 2 and T 1 gripped by the tool gripping claws 16 are mounted on the spindle 9 and the tool magazine 3, respectively. Release the grip of the gripping claws 16. Then, the headstock drive motor 21 is driven again to move the headstock 8 downward, so that the locking protrusion 23a of the stopper 23 is attached to the column 1.
The mount 10 is lowered together with the headstock 8 until it is locked on the upper surface, and after the mount 10 has stopped at a predetermined position, only the headstock 8 is lowered to the machining position, completing the tool exchange.

することなく簡単かつ迅速に行なえる。 As described above, the exchange arm mount 10 is moved together with the headstock 8 to the tool changer (the upper position in the above embodiment), and the exchange arm 15 grasps the tool, moves forward (to remove the tool), and rotates 180 degrees ( Since the tool is changed in the order of reversing the tool (reversing the tool) and backward movement (installing the tool), attaching and detaching the tool between the tool magazine 3 and the exchange arm 15, and between the exchange arm 15 and the spindle 9 are performed using the carriage, etc. This can be done easily and quickly without using a separate mechanism.

ようにしてもよい。 In the above embodiment, the headstock 8 and the mounting base 10 are moved in the vertical direction, but they may be moved in the horizontal direction. Further, the spring 24 constituting the holding mechanism is not necessarily necessary because when the mounting base 10 moves in the vertical direction, it performs a similar function due to the gravity of the mounting base 10 itself. Further, the tool gripping pawl 16 may be driven by the cylinder 17 or may be gripped by a spring.

具交換の全自動化も容易である。 As is clear from the above explanation, according to the present invention, the headstock and the exchange arm mounting base are moved to the tool exchange position, and there, the exchange arm exchanges the tool on the spindle with the tool in the tool magazine. Therefore, the conventionally used complicated mechanism such as a carriage is no longer necessary, the structure can be simplified, and the tool changer can be housed compactly in the column. Furthermore, in the past, attaching and detaching tools using a carriage required complicated and precise operations, and it took time to change tools, but in the case of the present invention, the headstock and exchange arm mount can be moved, and the exchange arm can be moved. Since only simple operations such as reciprocating and rotation are required, tools can be changed quickly and it is easy to fully automate tool changes.
