As seen in Publication No. 115992, a processing unit having a drive motor is provided on the base via a slide table that is driven in the front and back direction, and a movable rail at the front and a fixed rail at the rear are installed on the outer periphery of the unit. Further, a plurality of gearing heads are disposed on the outer periphery of the rail and supported by the annular rail, and these are rotated along the rail by an index table above the rail to select any one of them. The one piece on the movable rail is selectively placed on the movable rail, so that when the processing unit moves forward from the rearward end position, the one piece on the movable rail moves forward together with the movable rail and touches the workpiece in front of it. A type in which a predetermined machining is turned is known, but in this case, the movable rail stops together with the one piece on the rail when the machining unit moves a little forward from the backward end position. It is necessary to be able to interconnect the unit with the one.

されるようにした。 Although the above is not particularly different from the conventional one, according to the present invention, for example, as clearly shown in FIG. 13
The arm 15 is always connected to the cylinder 13.
The pressure fluid introduced inside the tube pushed it toward the contracting side.

前方への移動が防止される。 Thus, when the processing unit 5 is moved from the backward end position shown in FIG. 4 to a slightly advanced position close to the movable rail 6 as shown in FIG. The state shown in FIG. 9 is obtained from the state shown in FIG. That is, the cylinder 1
3 is accompanied by the unit 5 and the piston rod 1
4, the spring 12 stretches somewhat and its elasticity is reduced, but at this time the cylinder 13 increases its internal volume and supplies a corresponding amount of the pressure fluid. As a result of the reduction 18, the cylinder 13 is always filled with the pressure fluid, and thus the arm 15 is pushed toward the contraction side by the pressure fluid. In other words, the movable rail 6 is always subjected to the pressing force of the pressure fluid to prevent the movable rail 6 from accidentally moving forward when only the spring 12 is used.
該圧力流体は必要に応じ該シリンダ１３内から

出時の抵抗は多少とも負荷となり勝ちであり、こ
れを無くすことが好ましい。 Preferably, the pressure fluid is discharged from within the cylinder 13 as needed so that it does not become an unnecessary load. That is, when the unit 5 is moved from the state shown in FIG. 9 to the reverse end position, the internal volume of the cylinder 13 is reduced as shown in FIG. 8, and a corresponding amount of the pressure fluid is removed. is discharged to the outside via the regulator 24, and any resistance during discharge tends to become a load, so it is preferable to eliminate this resistance.

に排出される状態とに切換えられるようにした。 The second invention meets such requirements, and is equipped with a detector 19 for detecting the backward end position of the processing unit 5 and the forward position close to the movable rail 6. When the cylinder 13 is in operation, the pressure fluid is introduced into the cylinder 13, and when the cylinder 13 is not in operation, the pressure fluid in the cylinder 13 is discharged to the outside.

に伴われて前後動するドツグ２２と協動すべく構
成する。 To explain this in detail, for example, as clearly shown in FIG. 7, a switching valve 20 is interposed in the communication passage 18a, so that the inside of the cylinder 13 can be freely switched between the supply source 18 and the atmosphere open side 21. In addition, the detector 19 is composed of, for example, a micro valve that controls switching of the switching valve 20, which is connected to the processing unit 5.
It is constructed so as to cooperate with the dog 22 which moves back and forth in accordance with the movement.

流体が排出されるようにした。 That is, the detector 19 is located on the machine frame 7a side, and the dock 22 is located below it, as shown in FIG.
At the backward end position and the forward position of the processing unit 5, the detector 19 is released from the pressure by the dot 22 and operates, as shown in FIGS. According to the associated operation, the supply source 18 is communicated into the cylinder 13 to introduce the pressure fluid, but in the intermediate position, the detector 19 is pushed by the dot 22 and becomes inactive.
According to the accompanying operation of the switching valve 20, the inside of the cylinder 13 is communicated with the atmosphere opening side 21, so that the pressure fluid is discharged.

0c, and an air pipe or other connecting pipe 20 between the micro valve 19 and the micro valve 19 that controls the micro valve 19.
d shall be provided. As described above, the communication passage 18a for introducing the pressure fluid, that is, the pressure air, is equipped with a regulator 24 to keep the fluid at a constant pressure, and in substantially the same way, the pressure fluid, for example, the pressure oil, is operated as described above. A relief valve 25 was provided in the circuit leading to the cylinder 2 to maintain the fluid at the constant pressure.

６を備えてこれを同時に作動させる。 To explain its operation, the processing unit 5 is always located at a rearward end position slightly separated from the movable rail 6, as shown in FIGS. 1, 4, and 5, for example. In this position, the detector 19 is activated and the pressure fluid is introduced into the cylinder 13 as shown in FIG. In other words, the movable rail 6 is strongly pushed backward by the spring 12 and the pressure fluid and is bound to the fixed rail 7 side. Therefore, in this state, when any one of the gearing heads 9 is rotated and guided onto the rail 6, the gearing heads 9
Even if the rail 6 is somewhat heavy and its centrifugal force acts on the rail 6, the rail 6 will not move forward inadvertently. Next, considering the case where the processing unit 5 moves forward, the detector 19 becomes inactive at the intermediate position and the pressure fluid is once discharged, and then reaches the forward position as shown in FIG. 6, for example. Then, the movable rail 6 is again pressed by the spring 12 and the pressure fluid to the selected gearing head 9 on the rail 6, as shown in FIG. 9, for example. In this state, the machining unit 5 becomes interconnected with the gearing head 9, and with the continued advancement of the machining unit 5, the gearing head 9 moves together in its coupled state. You can move it forward and get the desired action. At this time, if necessary, the mechanical clamp mechanism 2 as shown by the chain line in FIG.
6 and operate them simultaneously.

えられる。 Next, if we consider the case where the processing unit 5 moves backward together with the head 9, the state shown in FIG. That cylinder 1
3, the pressure fluid is discharged, and thus the telescoping arm 15 is in a state where only the spring 12 acts on the contraction side, and can be extended relatively easily. That is, upon the subsequent backward movement of the unit 5,
The telescoping arm 15 does not receive a large load. Next, the unit 5 returns to the above-mentioned backward movement end position, and the arm 15 is again introduced to the pressure fluid, for example, in a state as shown in FIG. 8, and is ready for the next operation.

This eliminates the above-mentioned disadvantages of the type using only springs, and has the effect of providing good bonding between the movable rail and the processing unit. Furthermore, the second
According to the invention, when the processing unit moves to the backward movement end position, the pressure fluid is discharged from the cylinder to the outside, so that the pressure fluid does not become a load, and the effect is that a light backward movement can be obtained. has.
