Description

【０００１】
【産業上の利用分野】
この発明は、スプリング式硬さ計を昇降スピンドルの下端に連結する硬さ計連結ジョイントに関するものである。
【０００２】
【従来技術とその問題点】
スプリング式硬さ計とは加圧面から突出するスプリング付勢された圧針を有し、加圧面を試料に押し付け、圧針によって試料の硬さを測定する硬さ計のことである。この場合、試料の硬さを正確に測定するには、加圧面を試料に押し付けたとき、両者が的確に接触するようにする必要がある。これを目的とし、以前、出願人は特別の構成の硬さ計連結ジョイントを開発し、提案した。実公平６−５６０８号公報（特許文献１）に記載されているものがそれである。同公報のものでは、硬さ計が昇降スピンドルの下端に連結され、揺動可能に支持される。したがって、試料が平板状であり、加圧面がそれに押し付けられたとき、試料によって硬さ計が揺動し、加圧面と試料が接触する。
【０００３】
しかしながら、たとえば、試料が円筒状であるとき、同公報のものを使用することは適当ではない。加圧面を試料に押し付けると、試料の周方向において、その曲面によって硬さ計が揺動し、不安定であり、圧針の位置で加圧面と試料が接触せず、離れてしまうという問題があり、試料の硬さを正確に測定することができない。
【０００４】

【０００５】
【発明の目的】
したがって、この発明は、加圧面から突出するスプリング付勢された圧針を有し、加圧面を試料に押し付け、圧針によって試料の硬さを測定するスプリング式硬さ計を昇降スピンドルに連結する硬さ計連結ジョイントにおいて、円筒状の試料であっても、加圧面と試料が的確に接触し、試料の硬さが正確に測定されるようにすることを目的としてなされたものである。
【０００６】
【発明の構成】
この発明によれば、球面座が昇降スピンドルの下端に形成され、球面座のまわりにおいて、ねじみぞが昇降スピンドルの下端に形成される。さらに、袋ナットがねじみぞにねじ合わされ、透孔が袋ナットの底面に形成され、軸部が硬さ計の上端に設けられ、透孔に挿入され、拡大ヘッドが軸部の上端に形成される。拡大ヘッドは球面状をなし、袋ナットに収容され、球面座に対向する。したがって、試料が円筒状であるとき、まず、拡大ヘッドを袋ナットに係合させ、袋ナットおよび拡大ヘッドによって硬さ計を支持し、加圧面を試料または治具に押し付け、球面座によって拡大ヘッドを案内し、硬さ計を揺動させ、その角度を調節することができる。その後、水平方向において、適宜の調節機構によって試料を移動させ、その位置を試料の半径方向に調節し、球面座によって拡大ヘッドを案内し、硬さ計を揺動させ、その角度を調節し、圧針の位置で加圧面と試料を接触させることができる。その後、その状態で袋ナットを回転させ、ねじみぞによって袋ナットを締め付け、拡大ヘッドを球面座に押し付け、これによって硬さ計を固定することができる。
【０００７】
反対に、球面座を硬さ計の上端に形成し、球面座のまわりにおいて、ねじみぞを硬さ計の上端に形成してもよい。さらに、袋ナットをねじみぞにねじ合わせ、透孔を袋ナットの底面に形成し、軸部を昇降スピンドルの下端に設け、透孔に挿入し、拡大ヘッドを軸部の下端に形成し、袋ナットに収容し、球面座に対向させると、試料が円筒状であるとき、まず、袋ナットを拡大ヘッドに係合させ、拡大ヘッドおよび袋ナットによって硬さ計を支持し、加圧面を試料または治具に押し付け、拡大ヘッドによって球面座を案内し、硬さ計を揺動させ、その角度を調節することができる。その後、水平方向において、適宜の調節機構によって試料を移動させ、その位置を試料の半径方向に調節し、拡大ヘッドによって球面座を案内し、硬さ計を揺動させ、その角度を調節し、圧針の位置で加圧面と試料を接触させることができる。その後、その状態で袋ナットを回転させ、ねじみぞによって袋ナットを締め付け、球面座を拡大ヘッドに押し付け、これによって硬さ計を固定することができる。
【０００８】
【実施例の説明】
以下、この発明の実施例を説明する。
【０００９】
図１はこの発明にかかる硬さ計連結ジョイントを示す。この連結ジョイントはスプリング式硬さ計１を昇降スピンドル２の下端に連結するためのもので、昇降スピンドル２は垂直にのび、キャリジ３に支持されている。図２に示すように、キャリジ３はベース４から直立する支柱５に取り付けられており、支柱５に沿って昇降可能である。ハンドル６によってキャリジ３をロックすることもできる。レバー７によって昇降スピンドル２を操作し、これをキャリジ３に対し昇降させることもできる。さらに、分銅８を昇降スピンドル２の上端に取り付け、昇降スピンドル２を昇降自在に解放し、分銅８を昇降スピンドル２および硬さ計１に作用させることができる。硬さ計１は実公平６−５６０８号公報に記載されている硬度計と同様のもので、加圧面９から突出するスプリング付勢された圧針１０を有する。したがって、試料１１をベース４の試料台１２に載せ、加圧面９を試料１１に押し付け、圧針１０によって試料１１の硬さを測定することができる。試料１１は円筒状のゴムロールからなる。適宜の調節機構１３によって試料台１２および試料１１を移動させ、その位置を調節することもできる。
【００１０】
図３に示すように、この連結ジョイントは昇降スピンドル２の下端にねじ付けられた袋ナット１４を有する。さらに、袋ナット１４の下部に減径加工が施され、球面座１５が減径加工部の下面に形成され、球面座１５のまわりにおいて、ねじみぞ１６が減径加工部の外周面に形成されている。したがって、球面座１５が昇降スピンドル２の下端に形成され、球面座１５のまわりにおいて、ねじみぞ１６が昇降スピンドル２の下端に形成されているものである。さらに、袋ナット１７がねじみぞ１６にねじ合わされ、拡大ヘッド１８がそれと組み合わされている。拡大ヘッド１８は球面状をなし、袋ナット１７に収容され、球面座１５に対向する。さらに、軸部１９が硬さ計１の上端に設けられ、拡大ヘッド１８はその上端に形成されている。袋ナット１７は底面に形成された透孔２０を有する。そして、軸部１９が透孔２０に挿入され、拡大ヘッド１８が袋ナット１７に収容されているものである。したがって、透孔２０のまわりにおいて、拡大ヘッド１８が袋ナット１７に係合し、袋ナット１７および拡大ヘッド１８によって硬さ計１が支持される。
【００１１】
この連結ジョイントにおいて、まず、分銅８を昇降スピンドル２の上端に取り付け、その状態で昇降スピンドル２および硬さ計１を下降させ、加圧面９を試料１１に押し付けると、球面座１５によって拡大ヘッド１８が案内され、硬さ計１が揺動し、その角度が調節され、図４に示すように、円筒状の試料１１の母線Ｙ上で加圧面９と試料１１を接触させることができる。さらに、その後、水平方向において、調節機構１３によって試料台１２および試料１１を移動させ、その位置を試料１１の半径方向に調節すると、それによって硬さ計１が揺動し、その角度が調節され、圧針１０の位置で加圧面９と試料１１を接触させることができる。その後、その状態で袋ナット１７を回転させ、ねじみぞ１６によって袋ナット１７を締め付けると、拡大ヘッド１８を球面座１５に押し付け、これによって硬さ計１を固定することができる。したがって、その後、硬さ計１が揺動することはなく、その角度を調節された状態に保つことができる。
【００１２】
なお、硬さ計１を揺動させ、その角度を調節するとき、実物の試料１１に代えて試料１１と同一径の円筒状の鉄心などの治具を使用することが好ましい。この場合、その治具を試料台１２に載せ、硬さ計１の加圧面９を治具に押し付けると、治具によって圧針１０が押し返され、後退する。しかも、治具は硬く、圧針１０によって治具がへこむことはない。したがって、球面座１５によって拡大ヘッド１８が案内され、硬さ計１が揺動し、その角度が調節され、圧針１０の位置で加圧面９と試料１１が接触したとき、圧針１０は完全に押し返される。したがって、硬さ計１によってそれを読み取り、確認することができる。その後、その状態で袋ナット１７を回転させ、硬さ計１を固定すればよく、その調節操作は容易である。
【００１３】
したがって、硬さ計１の角度調節後、昇降スピンドル２および硬さ計１を一旦上昇させ、試料１１を試料台１２に載せ、硬さ計１を再度下降させ、加圧面９を試料１１に押し付けると、袋ナット１７、拡大ヘッド１８および球面座１５によって硬さ計１が固定され、揺動せず、その角度が調節された状態に保たれる。したがって、圧針１０の位置で加圧面９と試料１１が接触し、試料１１の硬さを正確に測定することができる。さらに、硬さの測定後、試料１１を次の試料と交換し、それを試料台１２に載せ、硬さ計１を再度下降させ、加圧面９を試料１１に押し付けることができ、同一径の試料１１であれば、その硬さを順次交互に測定することができる。
【００１４】
図５は他の実施例を示す。この実施例では、反対に、球面座２１が硬さ計１の上端に形成され、球面座２１のまわりにおいて、ねじみぞ２２が硬さ計１の上端に形成されている。さらに、袋ナット２３がねじみぞ２２にねじ合わされ、軸部が昇降スピンドルの下端に 設けられ、拡大ヘッド２４が軸部の下端に形成され、拡大ヘッド２４は球面状をなし、袋ナット２３に収容されており、球面座２１に対向する。
【００１５】
したがって、拡大ヘッド２４および袋ナット２３によって硬さ計１を支持し、加圧面９を試料１１または治具に押し付けることができる。さらに、拡大ヘッド２４によって球面座２１を案内し、硬さ計１を揺動させ、その角度を調節することができ、圧針１０の位置で加圧面９と試料１１を接触させることができる。その後、ねじみぞ２２によって袋ナット２３を締め付け、球面座２１を拡大ヘッド２４に押し付け、これによって硬度計１を固定することができる。したがって、その後、硬さ計１を再度下降させ、加圧面９を試料１１に押し付けると、圧針１０の位置で加圧面９と試料１１を接触させ、試料１１の硬さを正確に測定することができ、同様の作用効果を得ることができる。
【００１６】
【発明の効果】
以上説明したように、この発明によれば、円筒状の試料１１であっても、加圧面９と試料１１を的確に接触させ、試料１１の硬さを正確に測定することができ、所期の目的を達成することができるものである。

[0002]
[Prior art and its problems]
The spring-type hardness meter is a hardness meter that has a spring-biased pressure needle protruding from a pressure surface, presses the pressure surface against the sample, and measures the hardness of the sample with the pressure needle. In this case, in order to accurately measure the hardness of the sample, when the pressing surface is pressed against the sample, it is necessary to ensure that both are in good contact. For this purpose, the applicant has previously developed and proposed a specially constructed hardness meter connection joint. This is what is described in Japanese Utility Model Publication No. 6-5608 (Patent Document 1). In the publication, the hardness meter is connected to the lower end of the elevating spindle and supported so as to be swingable. Therefore, when the sample is flat and the pressure surface is pressed against it, the hardness meter is swung by the sample, and the pressure surface and the sample come into contact with each other.
[0003]
However, for example, when the sample is cylindrical, it is not appropriate to use the one disclosed in the publication. When the pressure surface is pressed against the sample, the hardness meter swings due to the curved surface in the circumferential direction of the sample, which is unstable, and the pressure surface and the sample do not come into contact with each other at the position of the pressure needle. The hardness of the sample cannot be measured accurately.
[0004]

[0008]
[Explanation of Examples]
Examples of the present invention will be described below.
[0009]
FIG. 1 shows a hardness meter connecting joint according to the present invention. This connection joint is for connecting the spring-type hardness meter 1 to the lower end of the elevating spindle 2. The elevating spindle 2 extends vertically and is supported by the carriage 3. As shown in FIG. 2, the carriage 3 is attached to a support column 5 standing upright from the base 4, and can be moved up and down along the support column 5. The carriage 3 can also be locked by the handle 6. The lifting spindle 2 can be operated by the lever 7 and can be moved up and down with respect to the carriage 3. Further, the weight 8 can be attached to the upper end of the elevating spindle 2 to release the elevating spindle 2 so that it can be raised and lowered, and the weight 8 can be applied to the elevating spindle 2 and the hardness meter 1. The hardness meter 1 is the same as the hardness meter described in Japanese Utility Model Publication No. 6-5608, and has a spring-biased pressure needle 10 protruding from the pressure surface 9. Therefore, the sample 11 can be placed on the sample table 12 of the base 4, the pressure surface 9 can be pressed against the sample 11, and the hardness of the sample 11 can be measured by the pressure needle 10. The sample 11 consists of a cylindrical rubber roll. The sample stage 12 and the sample 11 can be moved by an appropriate adjustment mechanism 13 and the positions thereof can be adjusted.
[0010]
As shown in FIG. 3, the connecting joint has a cap nut 14 screwed to the lower end of the elevating spindle 2. Further, a diameter reducing process is applied to the lower part of the cap nut 14, a spherical seat 15 is formed on the lower surface of the reduced diameter processing part, and a screw groove 16 is formed on the outer peripheral surface of the diameter reducing processed part around the spherical seat 15. ing. Therefore, the spherical seat 15 is formed at the lower end of the lifting spindle 2, and the screw groove 16 is formed at the lower end of the lifting spindle 2 around the spherical seat 15. Further, a cap nut 17 is screwed into the screw groove 16 and an enlarged head 18 is combined therewith . The expansion head 18 has a spherical shape, is accommodated in the cap nut 17, and faces the spherical seat 15. Further, the shaft portion 19 is provided at the upper end of the hardness meter 1, and the enlarged head 18 is formed at the upper end thereof. The cap nut 17 has a through hole 20 formed on the bottom surface. The shaft portion 19 is inserted into the through hole 20, and the expansion head 18 is accommodated in the cap nut 17. Thus, around the hole 20, enlarged head 18 engages the cap nut 17, the hardness meter 1 is supported by the cap nut 17 and enlarged head 18.
[0011]
In this connection joint, first, the weight 8 is attached to the upper end of the elevating spindle 2, the elevating spindle 2 and the hardness meter 1 are lowered in this state, and the pressing surface 9 is pressed against the sample 11. , The hardness meter 1 is swung, and the angle thereof is adjusted. As shown in FIG. 4, the pressing surface 9 and the sample 11 can be brought into contact with each other on the generatrix Y of the cylindrical sample 11. Furthermore, after that, when the sample stage 12 and the sample 11 are moved by the adjusting mechanism 13 in the horizontal direction and the positions thereof are adjusted in the radial direction of the sample 11, the hardness meter 1 is thereby swung and the angle thereof is adjusted. The pressure surface 9 and the sample 11 can be brought into contact with each other at the position of the pressure needle 10. After that, when the cap nut 17 is rotated in this state and the cap nut 17 is tightened by the screw groove 16, the expansion head 18 is pressed against the spherical seat 15, thereby fixing the hardness meter 1. Therefore, thereafter, the hardness meter 1 does not swing, and the angle can be maintained in an adjusted state.
[0012]
When the hardness meter 1 is swung and its angle is adjusted, it is preferable to use a jig such as a cylindrical iron core having the same diameter as the sample 11 instead of the actual sample 11. In this case, when the jig is placed on the sample stage 12 and the pressing surface 9 of the hardness meter 1 is pressed against the jig, the pressure needle 10 is pushed back by the jig and moves backward. In addition, the jig is hard and the pressure needle 10 does not dent the jig. Therefore, when the enlarged head 18 is guided by the spherical seat 15, the hardness meter 1 is swung and the angle thereof is adjusted, and when the pressure surface 9 and the sample 11 come into contact with each other at the position of the pressure needle 10, the pressure needle 10 is pushed completely. returned. Therefore, it can be read and confirmed by the hardness meter 1. Thereafter, by rotating the cap nut 17 in that state, may be fixed hardness meter 1, its regulation operation is easy.

Therefore, after adjusting the angle of the hardness meter 1, the elevating spindle 2 and the hardness meter 1 are once raised, the sample 11 is placed on the sample table 12, the hardness meter 1 is lowered again, and the pressing surface 9 is pressed against the sample 11. Then, the hardness meter 1 is fixed by the cap nut 17, the enlarged head 18 and the spherical seat 15, and does not swing, and the angle thereof is maintained. Therefore, the pressure surface 9 and the sample 11 come into contact with each other at the position of the pressure needle 10 and the hardness of the sample 11 can be accurately measured. Furthermore, after the hardness is measured, the sample 11 can be replaced with the next sample, placed on the sample stage 12, the hardness meter 1 can be lowered again, and the pressing surface 9 can be pressed against the sample 11, and the same diameter can be obtained. If it is the sample 11, the hardness can be measured alternately by turns.
[0014]
FIG. 5 shows another embodiment. In this embodiment, conversely, the spherical seat 21 is formed at the upper end of the hardness meter 1, and the screw groove 22 is formed at the upper end of the hardness meter 1 around the spherical seat 21. Further, the cap nut 23 is screwed into the screw groove 22, the shaft portion is provided at the lower end of the elevating spindle , the expansion head 24 is formed at the lower end of the shaft portion, and the expansion head 24 has a spherical shape and is accommodated in the cap nut 23. It faces the spherical seat 21.
[0015]
Therefore, the hardness meter 1 can be supported by the expansion head 24 and the cap nut 23, and the pressing surface 9 can be pressed against the sample 11 or the jig. Furthermore, the spherical head 21 is guided by the magnifying head 24, the hardness meter 1 can be swung and the angle thereof can be adjusted, and the pressure surface 9 and the sample 11 can be brought into contact with each other at the position of the pressure needle 10.
