After that, the positioning member is moved backward to release the locked and fixed state of the head body, and then the head body is rotated by a predetermined angle by the rotating means, so that the other locking protrusion of the locking member and the positioning member are locked. Face the groove. Then, the positioning member is moved forward, and the positioning groove of the positioning member is fitted into the other locking protrusion of the locking member, thereby positioning and fixing the head body, and moving the main shaft of the head body to a predetermined position in the circumferential direction from the initial position. Hold and fix in the position where the dimensions are shifted. Drilling holes in the workpiece in this state can be done in 1. A machined hole or the like can be formed at a position close to a machined hole or the like.

The pressing rod (43a) of the head body (18) protrudes, and the distal end surface of the pressing rod (43a) touches one of the protrusions (23a) of the protruding member (21) that is integrally attached and fixed to the head body (18).
) and presses the protruding member (21), the head main body (18) rotates counterclockwise and the first locking protrusion (32a) of the locking member (30) is pressed. ) faces the positioning member (39) held at the retracted end. After that, when the positioning cylinder (36) is operated, the rod (
The positioning member (39) attached and fixed to the front end of the head body (18) moves forward toward the head body (18), and the positioning groove (40)
is fitted and locked to the first locking protrusion (32a) of the locking member (30). At this time, since the circumferential surface of the second locking protrusion (32a) is formed into an arcuate surface, it reliably fits into the first locking protrusion (32a) of the positioning groove (40), and the head The main body (18) can be positioned with high precision. When the transmission gear (24) is rotated by the driving force of a drive motor (not shown) in this state, each main shaft (24) is
6a) (26b), the rotational force is transmitted to each main shaft (28a
) (26b), machined holes (2
a') (2c') (2e') (2a') is formed. In this way, the holes (2a') (2c') (2e') (2a
When the formation of the rotation means (41 ) configuring the second hydraulic cylinder (42b)
At the same time that the pressing rod (43b) of the first hydraulic cylinder (42a) protrudes, the pressing rod (43a) of the first hydraulic cylinder (42a) retracts. When the pressing rod (43b) of the second hydraulic cylinder (42b) protrudes, the Ikekata protrusion (23b) of the protruding member (21) of the head body (18) is pressed by the pressing rod (43b'I). , This pressing causes the head body (18) to rotate clockwise, and the locking member (30)
The second locking protrusion (32b) faces the positioning member (39) held at the retracted end. Thereafter, the positioning cylinder (36) is operated to advance the positioning member (39) at the front end of the rod (38), and the positioning member (39) at the front end of the rod (38) is moved forward.
(40) on the second locking protrusion (32) of the locking member (30).
b) to hold and fix each main shaft (26a) (26b) of the head body (18) at a position shifted by a predetermined distance in the circumferential direction from the initial position.
When a)<26b) is rotated as described above, the machined hole (2a") (2c') of the workpiece (1") is
