本考案は、硬度計に釦ける試料受台に関し、特に環状試
料を水平に載置しうる試料受台に関する。[Detailed Description of the Invention] The present invention relates to a sample holder that can be attached to a hardness tester, and more particularly to a sample holder that can horizontally place an annular sample.
従来、環状試料の硬さを測定する場合は、平らな試料受
台上に環状試料を水平に載置してから、所定の操作を施
すことにより、環状試料の被測定部分に圧子で圧痕をつ
けて、との圧痕大きさから環状試料の硬さを測定するこ
とが行なわれている。Conventionally, when measuring the hardness of a ring-shaped sample, the ring-shaped sample is placed horizontally on a flat sample holder, and then a predetermined operation is performed to make an impression with an indenter on the part to be measured of the ring-shaped sample. The hardness of a ring-shaped sample is measured from the size of the indentation made by applying it.
ところで、従来の硬度計にむける試料受台では、環状試
料の裏面の平面度が悪いと、この環状試料を試料受台上
に載置したときに僅かながらガタつきを生じて不安定と
なり、正確な硬さ測定を行なえないという問題点がある
。By the way, with conventional sample holders for hardness testers, if the flatness of the back surface of the annular sample is poor, when the annular sample is placed on the sample holder, it may wobble slightly and become unstable, making it difficult to obtain accurate results. There is a problem that accurate hardness measurements cannot be performed.
本考案は、このような問題点を解決しようとするもので
、試料受台上に環状試料を３点支持により安定よく支持
して、正確な硬さ測定を行なえるようにした、硬度計に
あ−ける３点支持式環伏試料受台を提供することを目的
とする。The present invention aims to solve these problems by developing a hardness tester that stably supports an annular sample on a sample holder using three-point support to enable accurate hardness measurements. The object of the present invention is to provide a three-point support encircling sample holder.
このため、本考案の硬度計における３点支持式環状試料

環状試料の他の２部分を局部的に支持する２条の突条と
で形成されたことを特徴としている。For this reason, the three-point support type annular sample holder in the hardness meter of the present invention is provided with a protrusion on which the annular sample is placed horizontally by pressing a button on the sample holder that is movably provided on the hardness meter main body.
In order to support the annular sample at approximately three points, the protrusion includes a main protrusion that locally supports the portion to be measured of the annular sample below the indenter axis, and a V-shaped extension extending from the main protrusion. It is characterized by being formed with two protrusions that locally support the other two parts of the annular sample.

ト２にはねじ軸３が螺合している。Hereinafter, a three-point support type annular sample holder attached to a hardness meter as an embodiment of the present invention will be explained with reference to the drawings.
The figure is a front view showing a hardness meter equipped with a book holder, and FIG. 2 is a view taken from the ■-■ arrow in FIG. A screw shaft 3 is screwed into the nut 2.

るようになっている。! In addition, a sample holder 4 is attached to the upper end of this screw shaft 3, and when the handle 2a is operated to rotate the nut 2, the screw shaft 3 is raised and lowered, and the sample holder 4 is also raised and lowered. It is supposed to be done.
さらに、この試料受台４の上面側には、輪切りにされた
鋼管等の円環状試料５を水平に載置しうる、全体として
Ｖ字型をなす突起部６が形成されている。Further, on the upper surface side of the sample holder 4, a projection 6 having an overall V-shape is formed on which a ring-shaped sample 5 such as a cut steel pipe can be placed horizontally.

いる。As shown in FIGS. 1 and 2, this protrusion 6 has a main protrusion 6a that can locally support the portion to be measured 5a of the annular sample 5 vertically below an indenter shaft 7 having an indenter 7a at its lower end. It is formed with two protrusions 6b and 6c that extend from the main protrusion 6a in a V-shape to locally support the other parts 5b and 5c of the annular sample 5. has been done.
すなわち、２条の突条６ｂ、６ｃの交わるところに主突
起部６ａが形成されて、全体としてＶ字型の突起部６が
形成されているのである。That is, the main protrusion 6a is formed where the two protrusions 6b and 6c intersect, forming a V-shaped protrusion 6 as a whole.
また、２条の突条６ｂ、６ｃのなす角はほぼ６０度とな

に載置すると、この円環状試料５をほぼ正三角形の各頂
点に近い３個所で支持することができる。In addition, the angle formed by the two protrusions 6b and 6c is approximately 60 degrees, so that when the annular sample 5 is placed horizontally on the protrusion 6, the annular sample 5 forms an approximately equilateral triangle. It can be supported at three locations near each vertex.

下端の圧子７ａ円環状試料５の被測定部分５ａに圧痕を
つけることが行なわれる。With the above-described configuration, the portion to be measured 5a of the annular sample 5 is supported horizontally at three points on the sample holder 4 via the projections 6.
To make an impression on the indenter 7a at the lower end, raise the sample holder 4 to a predetermined height by operating the handle 2a and rotating the nut 2, then lower the indenter shaft 1. An indentation is made on the portion to be measured 5a of the annular sample 5.
そして、との圧痕の大きさを顕微鏡等で観察することに
より、円環状試料５の硬さが測定されるのである。The hardness of the annular sample 5 is then measured by observing the size of the indentation using a microscope or the like.
このとき、円環状試料５はほぼ正三角形の各頂点に近い
３個所で突起部６に水平に支持されているので、円環状
試料５の裏面に釦ける平面度が悪い場合でも、ガタつく
ことがなく、正確に硬さの御兄を行なえるのである。At this time, since the annular sample 5 is horizontally supported by the projections 6 at three locations near each vertex of the equilateral triangle, even if the back surface of the annular sample 5 has poor flatness, it will not wobble. There is no such thing as hardness, and you can do it accurately.
なお、円環状試料５として、大小各種の大きさのものを
使用することもできるが、いずれの場合も、円環状試料
５の被測定部分５ａは圧子軸Ｉの下方の主突起部６ａ上
に載置される。Incidentally, as the annular sample 5, various sizes can be used, but in any case, the part to be measured 5a of the annular sample 5 is placed on the main protrusion 6a below the indenter axis I. It will be placed.
捷た、主突起部６ａと２条の突条６ｂ、６ｃとを一体に
形成する代わりに、突条６ｂ、６ｃを主突起部６ａから
切り離すようにして形成することも可能である。Instead of integrally forming the twisted main protrusion 6a and the two protrusions 6b, 6c, it is also possible to form the protrusions 6b, 6c separately from the main protrusion 6a.
さらに、突起部６の円環状試料５の裏面との当接部は狭
い面積の平面でも、エツジでもよい。Further, the contact portion of the protrusion 6 with the back surface of the annular sample 5 may be a narrow plane or an edge.
なお、環状試料５としては、円環状のものでも、角型の
環状のものでもその硬さを測定することができる。Note that the hardness of the annular sample 5 can be measured whether it is an annular sample or a square annular sample.
