〔発明の利用分野〕
本発明は、超精密旋盤等に使用される刃物台に
係り、特に刃物の刃先の姿勢を高精度に調整する
のに適した刃物台に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a tool rest used in ultra-precision lathes and the like, and particularly to a tool rest suitable for adjusting the attitude of the cutting edge of a cutter with high precision.

For example, as shown in FIG. 3, when processing the end face of a workpiece 3 held by a vacuum chuck 2 fixed to the spindle 1 into a highly accurate flat surface using a cutting tool 4, as shown in FIG. The cutting edge 5 is the bite 4
The posture must be adjusted with high precision so that it is parallel to the direction of movement. For example, Figures 5 and 6
As shown in the figure, if the cutting edge of the cutting tool 4 is inclined, feed marks 6 will appear on the machined surface of the workpiece 3, which will deteriorate the quality.

７に接するように配置されている。 When performing such machining, a tool rest as shown in FIGS. 7 and 8 has been proposed as a tool rest for holding the cutting tool 4. This tool rest has a base 1 with a hole 11 formed at one end and a screw hole 12 formed at the other end.
3, and when rotatably fitted into the hole 11 at one end, a hinge pin 14 is erected, and at the other end is the screw hole 1.
The holder 1 has a long hole 15 communicating with the holder 1, and has a pair of guides 16 on the upper surface for accommodating the cutting tool 4.
7 and a clamp plate 18 for fixing the cutting tool 4 inserted between the guide 16 and the holder 17.
and a bolt 19 and a bolt 20 for fixing the holder 17 to the base 13. A pair of brackets 21 are attached to the base 13.
A pair of adjustment bolts 22 are provided facing each other with the holder 17 in between. Further, a dial indicator 24 is attached to the base 13 via a bracket 23, and a dial indicator 24 is attached to the holder 1 through a bracket 23.
It is arranged so as to be in contact with 7.
このような構成で、バイト４をホルダ１７に取

を締めて加工を行なつていた。 With this configuration, after attaching the cutting tool 4 to the holder 17 and fixing the holder 17 to the base 13,
Test cut the test surface and dial indicator 24
Find the amount of correction for the tool bit 4 from the reading, loosen the bolt 20, turn the bolt 22 while looking at the indicator 24, correct the posture of the tool tool 4, and then turn the bolt 20.
The machine was being processed with the machine closed.

勢を調整するには、何度かの調整作業をくり返し
行なうことが必要であつた。 However, in such a tool post, since there is a gap δ between the hole 11 that connects the base 13 and the holder 17 and the hinge pin 14, adjustment cannot be made as indicated on the dial indicator 24. In other words, even if the dial indicator reads +Δ, there are many unstable factors such as tilting in the (-) direction due to the influence of the clearance δ, and it is necessary to adjust the posture of the cutting tool 4 several times. It was necessary to repeat the adjustment work.
本発明の目的は、上記従来技術に鑑み、調整の
容易な刃物台を提供するにある。
In view of the above-mentioned prior art, an object of the present invention is to provide a tool rest that is easy to adjust.
上記目的を達成するため、本発明においては、
刃物台のホルダを、ベースとの結合部と、刃物の

In order to achieve the above object, in the present invention,
The holder of the tool post is divided into a joint part with the base and a blade holding part, the parts are connected by an elastically deformable joint part, and the joint part is fixed to the base to eliminate unforeseen elements, It is characterized in that the posture of the knife can be easily and reliably adjusted.
以下、本発明の一実施例を図面にしたがつて説

An embodiment of the present invention will be described below with reference to the drawings.
第１図および第２図は、本発明の一実施例を示
すもので、同図において、第７図および第８図と
同じものは、同じ符号を付けて示してある。 1 and 2 show an embodiment of the present invention, and in these figures, the same parts as in FIGS. 7 and 8 are designated by the same reference numerals.
ホルダ２５は、ベース１３と結合するための結
合部２６と、バイト４を保持する保持部２７およ
び、結合部２６と保持部２７を接続する接続部２
８から成り、結合部２６がボルト２９でベース１
３に固定されている。 The holder 25 includes a coupling part 26 for coupling with the base 13, a holding part 27 for holding the cutting tool 4, and a connecting part 2 for connecting the coupling part 26 and the holding part 27.
The connecting part 26 is connected to the base 1 with a bolt 29.
It is fixed at 3.
このような構成であるから、ボルト２２を回し

くなり、バイト４の調整を確実に行なうことがで
きる。 With such a configuration, when the bolt 22 is turned and one end of the holder 25 is moved, the connecting portion 28 is elastically deformed. At this time, since the coupling portion 26 does not move, the amount of rocking of the holder 25 is accurately displayed by the dial indicator 24. Further, the holder 25 has bolts 22 and 2 at both ends.
9, there is no unstable element and the cutting tool 4 can be adjusted reliably.
以上述べた如く、本発明によれば、刃物台の不
