(b) 従来の技術
従来、この種の刃物台に工具を装着する場合、
予め均等な間隔で設けられた工具装着位置に対応
した形で工具を装着していた。(b) Conventional technology Conventionally, when attaching a tool to this type of tool post,
Tools were mounted in a manner that corresponded to tool mounting positions provided in advance at equal intervals.
(c) 発明が解決しようとする問題点
しかし、その場合、刃物台における各工具は、
略均等な間隔で配置されることになり、例えば、
ボーリングバーやドリル等の穴明け・内径工具を

約が生じる。(c) Problems to be solved by the invention However, in that case, each tool in the tool rest is
They will be arranged at approximately equal intervals, for example,
When installing drilling/inner diameter tools such as boring bars and drills, there are restrictions on the diameter of the workpiece that can be machined.

The maximum machining diameter DMX of the workpiece of the drilling/inner diameter tool 2 E installed at the tool installation position 1a is the tool 2A installed at the tool installation position 1a adjacent to the workpiece.
To machine a workpiece with a larger diameter than 2 B without interfering with it, use tools 2 A and 2 B.
It is necessary to remove it from the turret tool post 1. However, in this case, the three tool mounting positions 1a are used exclusively for machining large-diameter workpieces, reducing the number of tools that can be mounted on the turret tool rest 1, and meeting the demands of various machining operations. I had the inconvenience of not being able to answer.

It has a turret body 3 formed in a dodecagonal shape, and the turret body 3 is provided so as to be indexable and rotatable in directions of arrows A and B about a rotation center CT. Twelve tool mounting positions 1a are formed around the outer periphery of the turret body 3, and a plurality of tool holders 6 for holding bits 5 are removably mounted at any tool mounting position 1a. There is. Also,
At another tool mounting position 1a, a tool holder 7 for supporting a drilling/inner diameter tool 2 such as a boring bar or a drill is removably mounted. Additionally, an offset adapter 9 is similarly removably installed at the tool installation position 1a 1 in the upper right corner of the figure, and the offset adapter 9 has a tool holding hole 9a.

が可能となる。(g) Effects of the Invention As explained above, according to the present invention, the turret body 3 is rotatably provided, and a plurality of tool mounting positions 1a are provided on the outer periphery of the turret body. In the turret turret 1,
The turret body 3 is rotatably and indexably provided at a position corresponding to the tool mounting position and an intermediate position MP between the tool mounting positions, and at least one offset adapter 9 is removably provided at the tool mounting position 1a. , the offset adapter 9
In addition, a tool holding means such as a tool holding hole 9a capable of offset positioning the drilling/inner diameter tool at an intermediate position between the tool mounting position where the offset adapter is mounted and a tool mounting position adjacent to the mounting position is provided. , the tool mounting position 1a 2 adjacent to the tool mounting position 1a 1 where the offset adapter is mounted on the side where the tool holding means 9a is offset is configured so that no tool is mounted. When machining a workpiece with the drilling/inner diameter tool 2 positioned at an intermediate position between the two tool mounting positions 1a 1 , 1a 2 , both tool mounting positions 1a 1 ,
It becomes possible to process in a form that makes full use of the 1a2 space. In other words, conventionally, when machining a large diameter workpiece that cannot be machined using only the space of a single tool mounting position, two tool mounting positions on both sides of the tool mounting position where the drilling/inner diameter tool 2 is mounted are used. Regardless of whether or not all of the space for the tool installation positions on both sides is actually needed, if the tools attached to the workpiece are not removed at the same time, the workpiece and tools will interfere and machining will become impossible. However, in the present invention, the tool holding means is offset positioned at an intermediate position between the tool mounting position where the offset adapter is mounted and the tool mounting position adjacent to the tool mounting position, and furthermore, the tool holding means is positioned at the offset side. Since the tool mounting position 1a 2 adjacent to the tool mounting position 1a 1 where the offset adapter is mounted is set in a state where no tool is mounted, the two adjacent tool mounting positions 1a 1 and 1a 2 are Space can be utilized to the fullest around the intermediate position, and machining of large-diameter workpieces can be easily accommodated by sacrificing only one tool mounting position. Also, since the tool mounting positions on both sides of the tool mounting position where the tool is mounted are not sacrificed,
Accordingly, more tools can be mounted on the turret tool post 1, making it possible to meet a variety of processing requests.
