本考案は、硬さ試験機に関し、特にその基準荷重負荷機構の改良に関する。 The present invention relates to a hardness tester, and more particularly to improvement of a standard load applying mechanism for the hardness tester.
【0002】[0002]
従来のロックウェル式硬さ試験機における基準荷重負荷機構として、試料上面 押さえ方式のものと圧子軸変位量計測方式のものとが知られている。 As a standard load applying mechanism in the conventional Rockwell hardness tester, a sample top surface pressing method and an indenter shaft displacement measuring method are known.
【0003】 そこで、まず試料上面押さえ方式の基準荷重負荷機構をそなえた硬さ試験機に ついて説明すると図4(a),(b)において、ロックウェル硬度計を構成する機枠1 に圧子軸11がバネ10で下方に付勢されながら上下動可能に装備されている。 圧子軸11下端部には、圧子13が装着されており、圧子13下方の圧子13 先端に対向する位置には、機枠1に支持される試料受台3が設けられている。Therefore, first, a hardness tester equipped with a reference load application mechanism of a sample top surface pressing type will be described. In FIGS. 4A and 4B, an indenter shaft is attached to a machine frame 1 constituting a Rockwell hardness tester. 11 is equipped with a spring 10 so as to be vertically movable while being urged downward. An indenter 13 is attached to the lower end of the indenter shaft 11, and a sample holder 3 supported by the machine frame 1 is provided below the indenter 13 at a position facing the tip of the indenter 13.
【0004】 試料受台3は機枠1にねじ軸15および同ねじ軸上下用ナット16を介して支 持されており、ねじ軸および試料受台3は、ねじ軸上下用ナットの回動により上 下に駆動されるようになっている。The sample pedestal 3 is supported on the machine frame 1 through a screw shaft 15 and a screw shaft up / down nut 16, and the screw shaft and the sample pedestal 3 are rotated by the screw shaft up / down nut. It is designed to be driven up and down.
【0005】 すなわち、試料受台3の試料4を載置した状態での上下位置調整により試料4 を測定可能な状態にするようになっている。That is, the sample 4 can be measured by adjusting the vertical position of the sample holder 3 with the sample 4 placed thereon.
【0006】 そして、筒状に形成された試料上面押さえ12が、その内部に圧子13先端部 を収容するとともに、その下端部が試料受台3上に載置された試料4に係合しう るように配設されている。Then, the cylindrical sample upper surface holder 12 accommodates the tip of the indenter 13 therein, and its lower end engages with the sample 4 placed on the sample holder 3. It is arranged so that.
【0007】 また、筒状に形成されたストッパ8が、圧子軸11、試料上面押さえ12およ び付勢機構(図示せず)を収容するように配設されて、その上端部が機枠1に圧 子13と同心状態に固着されている。Further, a cylindrical stopper 8 is arranged so as to accommodate the indenter shaft 11, the sample upper surface pressing member 12, and a biasing mechanism (not shown), and the upper end portion thereof is a machine frame. It is fixed concentrically with the pressure roller 13 at the position 1.
【0008】 試料上面押さえ12はストッパ8に相対変位可能に遊挿されており、試料上面 押さえ12は、押さえばね(図示せず)により構成された付勢機構(図示せず) により常時下方へ付勢されている。The sample upper surface pressing member 12 is loosely inserted into the stopper 8 so that the sample upper surface pressing member 12 can be moved downward by a biasing mechanism (not shown) composed of a pressing spring (not shown). Being energized.
【0009】 図中の符号2は重錘、符号6はダイヤルゲージ、符号7は作動カム、符号17 は係合片、符号9aはレバー9のピボット部をそれぞれ示している。In the figure, reference numeral 2 indicates a weight, reference numeral 6 indicates a dial gauge, reference numeral 7 indicates an actuating cam, reference numeral 17 indicates an engaging piece, and reference numeral 9 a indicates a pivot portion of the lever 9.
【0010】 そしてこの装置における基準荷重は、機械的に試料4が試料受台3と共に押し 上げられ、圧子13が試料4の上面によって押し上げられ、さらに試料上面押さ え12が試料4の上面に当たるまで押し上げられることにより付与され、その基 準荷重Fは圧子13が試料4の上面によって押し上げられてから試料上面押さえ 12が試料4の上面に当たるまでの距離L2だけバネ10が縮むことにより生ず る力により付与され(図4(a)参照)る。ここで基準荷重Fと距離L2の関係は フックの法則により[数1]式で与えられる。The reference load in this apparatus is such that the sample 4 is mechanically pushed up together with the sample receiving base 3, the indenter 13 is pushed up by the upper surface of the sample 4, and further the sample upper surface holder 12 hits the upper surface of the sample 4. The reference load F is applied by being pushed up, and the reference load F is a force generated by the spring 10 contracting by the distance L2 from when the indenter 13 is pushed up by the upper surface of the sample 4 until the sample upper surface pressing member 12 contacts the upper surface of the sample 4. (See FIG. 4A). Here, the relationship between the reference load F and the distance L2 is given by the formula [1] according to Hooke's law.
【0011】[0011]
【数1】 基準荷重F=(バネ10のバネ定数K)×(距離L2) 次に、圧子軸変位量計測方式の基準荷重負荷機構をそなえた硬さ試験機は、図 5(a),(b)に示すように、上述の試料上面押さえ方式の硬さ試験機から試料上面 押さえ12、ストッパ8が取除かれた構成となっていて、この場合、基準荷重は 試料4で圧子13を押し上げる(図5b)ことによって付与される。## EQU1 ## Reference load F = (spring constant K of spring 10) × (distance L2) Next, the hardness tester equipped with the reference load mechanism of the indenter shaft displacement measurement method is shown in FIG. As shown in (b), the hardness tester of the sample upper surface pressing method has a structure in which the sample upper surface pressing member 12 and the stopper 8 are removed. In this case, the reference load is the sample 4 and the indenter 13 is used. It is applied by pushing up (Fig. 5b).
【0012】 すなわち、圧子13が試料4に触れていない状態におけるバネ10の長さL0 と、圧子13が試料4によって押し上げられた状態におけるバネ10の長さL1 との差をダイヤルゲージ6で計測し、[数2]式となるように、試料受台3の押 上量を加減して基準荷重(F=K×L2)が付与される。That is, the dial gauge 6 measures the difference between the length L 0 of the spring 10 when the indenter 13 is not in contact with the sample 4 and the length L 1 of the spring 10 when the indenter 13 is pushed up by the sample 4. Then, the reference load (F = K × L2) is applied by adjusting the amount of push-up of the sample holder 3 so as to obtain the formula [2].

【数2】 L0−L1=L2## EQU00002 ## L0-L1 = L2
ところで、上述の試料上面押さえ方式の基準荷重負荷機構をそなえた硬さ試験 機には、作業者は、基準荷重を試料に加える作業として試料を載せたテーブルを 試料上面押さえが試料に当たるまで押し上げるだけでよく、熟練を要さないとい う長所があるが、試料寸法が、試料上面押さえ部より小さい場合に、図6(a)に 示すように、試料上面押さえで試料を押さえることができないために、基準荷重 を試料に加えることができない。 By the way, in the hardness tester equipped with the reference load application mechanism of the sample upper surface holding method, the operator just pushes up the table on which the sample is placed as the work of applying the reference load until the sample upper surface pressing hits the sample. However, if the sample size is smaller than the sample top holding part, it is not possible to hold the sample with the sample top holding as shown in Fig. 6 (a). , The standard load cannot be applied to the sample.
【0014】 また、図6(b)に示すように、試料の周辺部に基準荷重を加える場合に、試料 が試料上面押さえによって不安定になり、場合によっては試料がはずれることも ある。Further, as shown in FIG. 6B, when a reference load is applied to the peripheral portion of the sample, the sample becomes unstable due to the pressing of the sample upper surface, and in some cases, the sample may come off.
【0015】 さらに、図6(c)に示すように、試料上面に段差がある場合、試料上面押さえ で試料上面を押さえることができないという欠点がある。Further, as shown in FIG. 6C, when there is a step on the upper surface of the sample, there is a drawback that the upper surface of the sample cannot be pressed by the upper surface of the sample.
【0016】 さらにまた、試料上面に余分な傷をつけたくない場合、試料上面押さえで試料 上面を傷つけてしまうことから試料上面押さえが使用できない場合があるという 欠点もある。[0016] Furthermore, if it is desired not to scratch the upper surface of the sample, there is a drawback that the upper surface of the sample cannot be used because the upper surface of the sample is damaged by the upper surface of the sample.
【0017】 一方、圧子軸変位量計測方式の基準荷重負荷機構をそなえた硬さ試験機の場合 には、小さな試料や試料上面に段差のある試料、もしくは試料の周辺部に基準荷 重を加えたい場合に対しても制約を受けにくく、また圧痕以外に不必要な傷を試 料上面に与えないという長所があるが、基準荷重を、圧子軸の変位量を表示する 変位計(ダイヤルゲージ等)を見ながら試料を載せたテーブルの上げ具合を加減 して加える必要があり、安定して基準荷重を加えるには若干の熟練を要するとい う欠点がある。On the other hand, in the case of a hardness tester equipped with a reference load mechanism of the indenter shaft displacement measurement method, a reference load is applied to a small sample, a sample with a step on the upper surface of the sample, or the periphery of the sample. It has the advantage that it is not subject to restrictions even when it is desired, and that it does not cause unnecessary scratches other than indentations on the top surface of the sample. However, a displacement gauge (such as a dial gauge) that displays the displacement of the indenter shaft as the reference load. ), It is necessary to adjust the degree of lifting of the table on which the sample is placed, and it takes some skill to stably apply the reference load.
【0018】 このように、従来の硬さ試験機では、基準荷重の加え方が、試験機に対して機 構的に一台の試験機に一つの方式が固定的に備えられているために、2種類の基 準荷重の加え方の少なくともいずれか一方の短所を備えざるを得ないという問題 点がある。As described above, in the conventional hardness tester, the method of applying the reference load is mechanically fixed to one of the testing machines, because one method is fixedly provided. However, there is a problem in that at least one of the two methods of applying the standard load must be provided.
【0019】 本考案は、このような問題点の解決をはかろうとするもので、試料上面押さえ を機枠に対して着脱可能に取付けることにより、一台の硬さ試験機で試料上面押 さえ方式と圧子軸変位量計測方式との両方式による基準荷重の負荷付与が選択し て行なえるようにした硬さ試験機の基準荷重負荷機構を提供することを目的とす る。The present invention is intended to solve such a problem. By mounting the sample upper surface retainer to the machine frame in a detachable manner, it is possible to press the sample upper surface with a single hardness tester. It is an object of the present invention to provide a standard load applying mechanism for a hardness tester, which can selectively apply a standard load by both the method and the indenter shaft displacement measurement method.
【0020】[0020]
上述の目的を達成するため、本考案の硬さ試験機の基準荷重負荷機構は、硬さ 試験機において、機枠と、同機枠に上下動可能に装備された圧子と、同圧子に対 向するようにその下方向に配設されて上記機枠に支持された試料受台とをそなえ 、同試料受台に載置された試料に下端部を係合すべく、上記圧子の近傍に配設さ れた試料上面押さえが、上記機枠に着脱可能に取り付けられたことを特徴として いる。 In order to achieve the above-mentioned object, the standard load applying mechanism of the hardness tester of the present invention is such that in the hardness tester, the machine frame, the indenter vertically movable in the machine frame, and the indenter And a sample holder supported by the machine frame, which is disposed in the lower direction, and is arranged near the indenter so that the lower end portion is engaged with the sample placed on the sample holder. It is characterized in that the installed sample top surface retainer is detachably attached to the machine frame.

A standard load is applied by the indenter shaft displacement measurement method.

【0024】 この実施例は、ロックウェル式硬さ試験機を例にしており、ロックウェル式硬 さ試験機を構成する機枠1に圧子軸11がバネ10で下方に付勢されながら上下 動可能に装備されている。In this embodiment, a Rockwell hardness tester is taken as an example, and an indenter shaft 11 is vertically moved while being urged downward by a spring 10 on a machine frame 1 constituting the Rockwell hardness tester. Equipped as possible.
【0025】 圧子軸11下端部には、圧子13が装着されており、圧子13下方の圧子13 先端に対向する位置には、機枠1に支持される試料受台3が設けられている。An indenter 13 is attached to the lower end of the indenter shaft 11, and a sample holder 3 supported by the machine frame 1 is provided below the indenter 13 at a position facing the tip of the indenter 13.
【0026】 試料受台3は機枠1にねじ軸15およびねじ軸上下用ナット16を介して支持 されている。The sample holder 3 is supported by the machine frame 1 via a screw shaft 15 and a screw shaft vertical nut 16.
【0027】 ねじ軸15および試料受台3は、ねじ軸上下用ナット16の回動により上下に 駆動されるようになっている。The screw shaft 15 and the sample holder 3 are vertically driven by the rotation of the screw shaft vertical nut 16.
【0028】 すなわち、試料受台3の試料4を載置した状態での上下位置調整により試料4 を測定可能な状態にするようになっている。That is, the sample 4 can be measured by adjusting the vertical position of the sample holder 3 with the sample 4 placed thereon.
【0029】 そして、袋ナット状に形成された試料上面押さえ12が、その内部に圧子13 先端部を収容するとともに、その下端部が試料受台3上に載置された試料4に係 合しうるように配設されている。The sample upper surface holder 12 formed in the shape of a cap nut accommodates the tip of the indenter 13 therein, and the lower end of the sample upper surface retainer 12 is engaged with the sample 4 placed on the sample holder 3. It is arranged so that
【0030】 すなわち試料の上面を押さえるための試料上面押さえ12の内周面にめねじ部 12aが刻設され、このめねじ部12aが、機枠1に刻設された雄ねじ部1aに 螺合することにより、試料上面押さえ12が機枠1に着脱可能に取付けられてい る。符号12bは固定ねじを示している。That is, an internal thread portion 12a is engraved on the inner peripheral surface of the sample upper surface pressing member 12 for pressing the upper surface of the sample, and the internal thread portion 12a is screwed onto the external thread portion 1a engraved on the machine frame 1. By doing so, the sample upper surface holder 12 is detachably attached to the machine frame 1. Reference numeral 12b indicates a fixing screw.
【0031】 試料上面押さえ12の下端は、試料3の上面形状に応じた形状と、試料4と圧 子13との係合状態が直接見られる切り欠き部をもった形状になっている。The lower end of the sample upper surface holder 12 has a shape corresponding to the upper surface shape of the sample 3 and a shape having a cutout portion in which the engagement state between the sample 4 and the pressure element 13 can be directly seen.
【0032】 例えば、試料4が円筒の場合は逆V字型に、試料4が平面の場合は、第3図に 示すように、基部12cと、基部12cに立設された押圧肢12dとにより形成 されていて、試料4の上面が圧子13の軸に対し直交する一定の姿勢に押圧しな がら、押圧肢12d相互間の切り欠き部から試料4と圧子13との係合状態が見 られるようになっている。For example, when the sample 4 is a cylinder, it has an inverted V shape, and when the sample 4 is a plane, as shown in FIG. 3, the base 12c and the pressing limb 12d provided upright on the base 12c are used. While being formed, the upper surface of the sample 4 is pressed in a constant posture orthogonal to the axis of the indenter 13, and the engagement state between the sample 4 and the indenter 13 can be seen from the notch between the pressing limbs 12d. It is like this.
【0033】 上述の構成において、試料上面押さえ12を用いて基準荷重を加える場合の段 取りとしては、図2(a)に示すように袋ナット状の構造をした試料上面押さえ1 2を、圧子13の先端と試料上面押さえ12の底部との間隔が、図4(a)に示す ような基準荷重に相当するバネ変位量L2になるよう機枠1に刻設された雄ねじ 部を利用して試料上面押さえ12を上下させて調整しながら取付ける。In the above-mentioned configuration, when the reference load is applied using the sample upper surface holder 12, the sample upper surface holder 12 having a cap nut-like structure as shown in FIG.

The sample upper surface holder 12 is moved up and down to be adjusted.
【0034】 試料上面押さえ12の位置調整後は、固定ネジ12bを用いて試料上面押さえ 12を固定する。After adjusting the position of the sample upper surface holder 12, the sample upper surface holder 12 is fixed using the fixing screw 12b.
【0035】 以上の段取り完了後、試料上面押さえ12を用いた基準荷重を加える作業が実 施可能となる。After the above-mentioned setup is completed, the work of applying the reference load using the sample upper surface holder 12 can be performed.
【0036】 次に、圧子軸変位量計測方式で基準荷重を試料に加える際の段取りとして、試 料上面押さえ12を機能させないようにするために、試料上面押さえ12を図2 (b)に示すように試料上面押さえ12を十分に上方向へ持ち上げた後、固定ネジ 12bで試料上面押さえ12を固定する。Next, as a setup for applying a reference load to the sample by the indenter shaft displacement measurement method, the sample upper surface retainer 12 is shown in FIG. 2B in order to prevent the sample upper surface retainer 12 from functioning. After sufficiently lifting the sample upper surface holder 12 upward, the sample upper surface holder 12 is fixed with the fixing screw 12b.
【0037】 あるいは、図2(c)に示すように、試料上面押さえ12を、固定ネジ12bを 緩めることで機枠1から取り外してしまってもよい。Alternatively, as shown in FIG. 2C, the sample upper surface holder 12 may be removed from the machine frame 1 by loosening the fixing screw 12b.

A load can be applied to the sample.
【0041】 また、試料上面に段差がなく十分に試料上面押さえ12より大きな試料面を持 つ試料で試料面の周辺部でない部分に基準荷重を加える際には、試料上面押さえ 12が機能する位置に試料上面押さえ12を設置することで、熟練を要さない試 料上面押さえ方式で試料に基準荷重を加えることができる。Further, when a reference load is applied to a portion of the sample which has no step on the sample upper surface and has a sample surface which is sufficiently larger than the sample upper surface pressing member 12 and which is not a peripheral portion of the sample surface, the position where the sample upper surface pressing member 12 functions By installing the sample upper surface holder 12 in the sample, a reference load can be applied to the sample by a sample upper surface pressing method that does not require any skill.
