There is. On the other hand, there is an increasing number of compound NC lathes that not only perform turning with fixed tools, but also have rotary tools on the tool post and can perform milling, drilling, and tapping in cooperation with C-axis control of the spindle. Further, in such a compound NC lathe, a technique relating to a tool post in which a tool can be replaced by an automatic tool replacement device in order to increase the number of tools that can be used is disclosed in JP-A-3-228506. When using a rotary tool in such a tool rest, the driving force from the driving body is transmitted to the rotary tool only when indexed to the machining position, and when indexed to the tool replacement position, the tool change It is necessary to position in the rotational direction as much as possible. Also in the above-mentioned Japanese Patent Laid-Open No. 3-228506, the sun gear is moved by the shifter in order to transmit the rotational driving force to either the X-axis rotary tool or the Z-axis rotary tool, and the rotation is disengaged from the sun gear. The tool is configured such that the claw and the gear are engaged with each other to hold the position in the rotation direction.

しかしながら、特開平３−２２８５０６号の技術では、中間軸上の太陽歯車を シフトしているため、Ｘ軸回転工具またはＺ軸回転工具を装着する装着部を複数 設けると、太陽歯車に噛み合っている全ての歯車が回転し、加工位置以外の回転 工具も回転するため、伝達効率の低下や安全性の問題を生じる。そのため、複数 の回転工具装着部を設けることができず、工具交換回数が増加して、生産能率を 低下させるという問題点を生じた。 本考案の目的は、前記問題点を解決するために創案されたものであり、駆動体 側駆動部と、回転工具側被駆動部との係脱動作と、回転工具装着部の回転方向位 置決め部材の係脱動作とを簡素な構成で確実に行うとともに、複数の回転工具装 着部を設けることが可能な複合ＮＣ旋盤の刃物台を提供することにある。 However, in the technique disclosed in Japanese Patent Laid-Open No. 3-228506, the sun gear on the intermediate shaft is shifted. Therefore, when a plurality of mounting parts for mounting the X-axis rotary tool or the Z-axis rotary tool are provided, the sun gear meshes with the sun gear. Since all the gears rotate and the rotating tools other than the machining position also rotate, there is a problem of reduced transmission efficiency and safety. As a result, it is not possible to provide a plurality of rotary tool mounting parts, and the number of tool changes increases, resulting in a problem of reduced production efficiency. The object of the present invention was created to solve the above-mentioned problems, and the engagement / disengagement of the driving unit side driving unit and the rotary tool side driven unit and the rotational direction position of the rotary tool mounting unit. An object of the present invention is to provide a tool rest of a compound NC lathe capable of reliably engaging and disengaging a deciding member with a simple structure and providing a plurality of rotary tool attachment parts.

An example in which the Z rotary tool 6 is indexed to the processing position will be described. The driven shaft 13 has a driven gear 13a formed in the central portion and a sliding hole 13b formed in the inner peripheral portion. A sliding member 35 is provided in the sliding hole 13b so as to be movable in the axial direction, and a positioning pin 32 is fixed to the sliding member 35 with a set screw 31. The positioning pin 32 penetrates the engaging elongated hole 13c formed in the driven shaft 13, and the sliding member 35 is movable with respect to the driven shaft 13 only in the axial direction. At the end of the sliding member 35 on the drive shaft 12 side, a concave groove (second engaging portion) 35a for engaging the convex engaging portion 12a and transmitting the rotational force is formed. The sliding member 35 is constantly urged toward the drive shaft 12 by the spring 33. Reference numeral 34 is a plug holding the spring 33. One end of the driven shaft 13 penetrates a hole portion 11b formed in the flange portion 11a of the turret shaft 11.

A predetermined Z rotary tool 6 is indexed to the machining position and clamped by a command from an NC device (not shown). At this time, the positioning pin 32 and the positioning groove 11c are engaged with each other, so that the rotary tool is positioned in the rotational direction. Pressure oil is supplied to one of the cylinder chambers 23a to advance the drive shaft 12 to the driven shaft 13 side. The convex engaging portion 12a at the tip of the drive shaft 12 and the concave groove 35a of the sliding member 35 are fitted together. When the drive shaft 12 is further advanced, the sliding member 35 moves against the biasing force of the spring 33, the positioning pin 32 is disengaged from the positioning groove 11c, and the rotational force of the drive shaft 12 is transmitted to the driven shaft 13. It will be possible. A driving force from a rotary tool driving body (not shown) is driven by the driving shaft 12, the convex engaging portion 12a, the concave groove 35a, the sliding member 35, the positioning pin 32, the driven shaft 13 (driven gear 13a), and the intermediate shaft 14 (intermediate shaft 14).

Pressure oil is supplied to the second cylinder chamber 23b to retract the drive shaft 12. The concave groove 35a of the sliding member 35 and the convex engaging portion 12a of the drive shaft 12 are disengaged from each other, and the positioning pin 32 is engaged with the positioning concave groove 11c by the urging force of the spring 33, so that the Z rotation is performed. The tool 6 is fixed at a predetermined rotational position. If indexed to the tool change position in this state, the tool can be changed. When the X rotary tool 5 is used, the X rotary tool 5 may be indexed to the processing position and the same operation as that of the Z rotary tool 6 may be performed.
