Description

本発明は、セラミックグリーンシートや樹脂フィルムのようなシート状の試験片の引張り強度を測定するのに適した強度測定用治具およびそれを用いたセラミックグリーンシートの強度測定方法に関するものである。 The present invention relates to a strength measuring jig suitable for measuring the tensile strength of a sheet-like test piece such as a ceramic green sheet or a resin film, and a method for measuring the strength of a ceramic green sheet using the same.

従来、セラミックグリーンシートのようなシート状試験片の引張り強度を測定するには、特許文献１に記載のような強度試験機を用いるのが一般的である。すなわち、試験片の両端部を把持する上下一対の把持具を備え、これら把持具を離間方向に移動させ、その時の反力を測定することで、試験片の引張り強度を測定することができる。 Conventionally, in order to measure the tensile strength of a sheet-like test piece such as a ceramic green sheet, a strength tester as described in Patent Document 1 is generally used. That is, it is possible to measure the tensile strength of the test piece by providing a pair of upper and lower gripping tools for holding both ends of the test piece, moving these gripping tools in the separating direction, and measuring the reaction force at that time.

ところが、上記のような強度試験機では、試験片を把持した把持具を上下方向に引っ張るように構成されているため、可動空間を確保するために上下方向の寸法が大きくなるという問題がある。また、試験片の引張り強度を、把持具の引張り方向の力で直接測定するため、押し込み機能しか持たない強度試験機には適用できない。
特開平７−２８６９４７号公報 However, since the strength tester as described above is configured to pull the gripping tool that grips the test piece in the vertical direction, there is a problem that the vertical dimension is increased in order to secure a movable space. Further, since the tensile strength of the test piece is directly measured by the force in the pulling direction of the gripping tool, it cannot be applied to a strength tester having only a pushing function.
JP-A-7-286947

そこで、本発明の目的は、小さな寸法で、かつ押し込み機能しか持たない強度試験機にも適用できる試験片の引張り強度を測定するための強度測定用治具およびそれを用いたセラミックグリーンシートの強度測定方法を提供することにある。 Accordingly, an object of the present invention is to provide a strength measuring jig for measuring the tensile strength of a test piece that can be applied to a strength tester having a small size and having only an indentation function, and strength of a ceramic green sheet using the same. It is to provide a measurement method.

前記目的を達成するため、請求項１に記載の発明は、試験片の引張り強度を測定するための強度測定用治具であって、上記試験片の一方の端部を固定するための第１の固定部を備えた本体と、上記試験片の他方の端部を固定するための第２の固定部と、上記本体から外部へ突出した操作部とを有し、上記本体に対して直線移動可能に設けられた可動部とを備え、上記操作部を上記本体に対して押し込み、上記第２の固定部が第１の固定部に対して離間する方向に上記可動部を移動させることで、上記試験片の引張り強度を測定可能としたことを特徴とする強度測定用治具を提供する。 In order to achieve the above object, the invention according to claim 1 is a strength measuring jig for measuring the tensile strength of a test piece, and is a first jig for fixing one end of the test piece. A main body provided with a fixing portion, a second fixing portion for fixing the other end of the test piece, and an operation portion protruding outward from the main body, and linearly moved with respect to the main body A movable part provided in a possible manner, by pushing the operation part against the main body and moving the movable part in a direction in which the second fixed part is separated from the first fixed part, There is provided a strength measuring jig characterized in that the tensile strength of the test piece can be measured.

本発明では、押し込み方向の力を、第１と第２の固定部間に働く引張り方向の力に変換するため、本体に対して直線移動可能に設けられた可動部に、本体から外部へ突出した操作部を設けてある。この操作部を本体に対して押し込むことで、第２の固定部が第１の固定部に対して離間方向に動き、第１と第２の固定部に両端部が固定された試験片に引張り力が作用する。操作部に作用させる荷重（力）を測定することで、試験片の引張り強度を測定することができる。
このように押し込み方向の力を引張り方向の力に変換しているので、上下方向の寸法を短縮できると同時に、押し込み機能しか持たない強度試験機に容易に適用できる。 In the present invention, in order to convert the force in the pushing direction into the force in the pulling direction that acts between the first and second fixed parts, the movable part provided so as to be linearly movable with respect to the main body protrudes from the main body to the outside. An operation unit is provided. By pushing this operation part against the main body, the second fixing part moves in the separating direction with respect to the first fixing part, and is pulled to the test piece whose both ends are fixed to the first and second fixing parts. Force acts. By measuring the load (force) applied to the operation unit, the tensile strength of the test piece can be measured.
Thus, since the force in the pushing direction is converted into the force in the pulling direction, the vertical dimension can be shortened, and at the same time, it can be easily applied to a strength tester having only a pushing function.

請求項２のように、操作部を、第１の固定部を間にして第２の固定部と反対側の部位に設けるのがよい。
すなわち、操作部と第２の固定部との位置関係によっては、操作部を押し込んだ時に可動部に回転モーメントが作用し、操作部への押し込み力が第２の固定部にダイレクトに伝わらず、試験片の正確な引張り強度を測定できない場合がある。そこで、操作部を第１の固定部を間にして第２の固定部と反対側の部位に設けることで、操作部への押し込み力が試験片の引張り力にダイレクトに変換され、試験片の正確な引張り強度を測定できる。 According to a second aspect of the present invention, it is preferable that the operation portion is provided at a site opposite to the second fixing portion with the first fixing portion interposed therebetween.
That is, depending on the positional relationship between the operation unit and the second fixed unit, a rotational moment acts on the movable unit when the operation unit is pushed in, and the pushing force on the operation unit is not directly transmitted to the second fixed unit, The exact tensile strength of the specimen may not be measured. Therefore, by providing the operation part at the opposite side of the second fixing part with the first fixing part in between, the pushing force to the operating part is directly converted into the tensile force of the test piece, Accurate tensile strength can be measured.

請求項３のように、第１の固定部および第２の固定部は、それぞれ粘着力によって試験片を固定する粘着手段を有するものとしてもよい。
一般的な強度試験機では、試験片の両端をクランプする把持具が用いられるが、セラミックグリーンシートのような薄くかつ強度の低い試験片では、クランプ部分で試験片が破断してしまい、正確な引張り強度を測定できないことがある。
そこで、粘着手段によって試験片を固定すれば、面で試験片を固定できるので、試験片の一部に応力が集中せず、試験片の破断を防止できる。
粘着手段としては、例えば粘着テープを用いてもよいし、糊やボンドなどの接着剤で接着固定してもよい。また、粘着性ラバーシートなどの粘着層を本体および可動部に設け、この粘着層に試験片を貼り付けてもよい。 As in claim 3, each of the first fixing portion and the second fixing portion may have an adhesive means for fixing the test piece by an adhesive force.
In a general strength tester, a gripping tool that clamps both ends of the test piece is used. However, in a thin and low-strength test piece such as a ceramic green sheet, the test piece breaks at the clamp part, which is accurate. The tensile strength may not be measured.
Therefore, if the test piece is fixed by the adhesive means, the test piece can be fixed on the surface, so that stress is not concentrated on a part of the test piece, and the breakage of the test piece can be prevented.
As the adhesive means, for example, an adhesive tape may be used, or it may be bonded and fixed with an adhesive such as glue or bond. Alternatively, an adhesive layer such as an adhesive rubber sheet may be provided on the main body and the movable part, and a test piece may be attached to the adhesive layer.

請求項４のように、本体および可動部の一方に滑車またはボールを備え、他方に滑車またはボールを転動自在にガイドするガイドレールを備えた構造としてもよい。
可動部の操作部を強度試験機によって下方に向かって押し込むことで、引張り強度を測定する場合には、試験片に作用する引張り力は、強度試験機の押し込み力と可動部の重量だけでなく、本体と可動部との間に働く摩擦力も影響する。
摩擦力には静摩擦力と動摩擦力とがあり、一定しない。そのため、摩擦力をできるだけ小さくすれば、引張り力の測定精度が向上する。そこで、請求項３では、可動部と本体との間に滑車またはボールと、ガイドレールとを組み合わせたガイド機構を設け、可動部と本体との間の摩擦力をできるだけ小さくしたものである。 According to a fourth aspect of the present invention, one of the main body and the movable part may be provided with a pulley or a ball, and the other may be provided with a guide rail that guides the pulley or the ball so as to be able to roll.
When measuring the tensile strength by pushing the operating part of the movable part downward with a strength tester, the tensile force acting on the test piece is not only the pushing force of the strength tester and the weight of the movable part. The frictional force acting between the main body and the movable part also affects.
There are static friction force and dynamic friction force, which are not constant. Therefore, if the frictional force is made as small as possible, the measurement accuracy of the tensile force is improved. Accordingly, in claim 3, a guide mechanism in which a pulley or a ball and a guide rail are combined is provided between the movable portion and the main body, and the frictional force between the movable portion and the main body is made as small as possible.

請求項５のように、セラミックグリーンシートの強度測定方法に本発明の強度測定用治具を利用すれば、セラミックグリーンシートの引張り強度を、小型の治具でかつ押込型の試験機を用いて容易に測定できる。 If the intensity | strength measuring jig | tool of this invention is utilized for the intensity | strength measuring method of a ceramic green sheet like Claim 5, the tensile strength of a ceramic green sheet will be used with a small jig | tool and an indentation type testing machine. Easy to measure.

請求項６では、請求項２と同様に、粘着手段を用いてセラミックグリーンシートの両端部をそれぞれ第１の固定部と第２の固定部とに固定するものである。
そのため、固定部におけるセラミックグリーンシートを破れを防止できる。 In the sixth aspect, similarly to the second aspect, both end portions of the ceramic green sheet are fixed to the first fixing portion and the second fixing portion, respectively, using an adhesive means.
Therefore, the ceramic green sheet in the fixed part can be prevented from being torn.

請求項１に係る発明によれば、第１と第２の固定部に働く引張り方向の力を押し込み方向の力に変換する機構を設けたので、強度測定用治具の上下方向の寸法を短縮できると同時に、押し込み機能しか持たない強度試験機にも容易に適用できる。 According to the first aspect of the present invention, since the mechanism for converting the tensile force acting on the first and second fixing parts into the pushing force is provided, the vertical dimension of the strength measuring jig is shortened. At the same time, it can be easily applied to a strength tester having only a push-in function.

以下に、本発明の実施の形態を図面を参照して説明する。
図１〜図２は本発明にかかる強度測定用治具の第１の実施形態を示す。
この強度測定用治具Ａは、本体１と、この本体１に対して上下方向に直線移動可能に設けられた可動部１０とで構成されている。 Embodiments of the present invention will be described below with reference to the drawings.
1 to 2 show a first embodiment of a strength measuring jig according to the present invention.
The strength measuring jig A is composed of a main body 1 and a movable portion 10 provided so as to be linearly movable in the vertical direction with respect to the main body 1.

本体１は、水平な面に載置される台板２と、台板２の上に直立固定された背面板３と、背面板３の前面の両側部に固定された一対のレール板４，５と、レール板４，５の前面に固定された門型の前面板６とで構成され、背面板３とレール板４，５と前面板６とはボルト７によって一体的に固定されている。前面板６の横枠部の下部前面には、粘着性ラバーシートよりなる第１固定部８が設けられている。レール板４，５の内側面には、上下方向に延びるガイドレール４ａ，５ａが形成されている。 The main body 1 includes a base plate 2 placed on a horizontal surface, a back plate 3 fixed upright on the base plate 2, and a pair of rail plates 4 fixed to both sides of the front surface of the back plate 3. 5 and a gate-shaped front plate 6 fixed to the front surface of the rail plates 4, 5. The rear plate 3, the rail plates 4, 5 and the front plate 6 are integrally fixed by bolts 7. . A first fixing portion 8 made of an adhesive rubber sheet is provided on the lower front surface of the horizontal frame portion of the front plate 6. Guide rails 4 a and 5 a extending in the vertical direction are formed on the inner side surfaces of the rail plates 4 and 5.

可動部１０は、上記レール板４，５の間に上下動自在に配置されたベース部１１と、ベース部１１の下端部の前面に固定されたブロック部１３とで構成されており、ブロック部１３はベース部１１に対してボルト１６によって一体的に固定されている。ベース部１１の両側部には、上下一対の滑車１４が取り付けられており、これら滑車１４がレール板４，５のガイドレール４ａ，５ａに沿って転動することで、可動部１０は本体１に対してほぼ抵抗なく上下動自在にガイドされる。ブロック部１３の前面は、上記前面板６の前面と前後方向同一高さに形成されており、ブロック部１３の上部前面には、粘着性ラバーシートよりなる第２固定部１５が設けられている。そのため、第１固定部８と第２固定部１５とが上下に対応し、かつ前後方向同一高さに配置される。ベース部１１の上端部は本体１の上面から上方に突出し、操作部１２を構成している。この操作部１２は、第１固定部８を間にして第２固定部１５と反対側の部位に設けられる。そのため、操作部１２を押し下げると、第２固定部１５が第１固定部８に対して下方、つまり第２固定部１５が第１固定部８に対して離間方向に移動することになる。 The movable part 10 is composed of a base part 11 disposed between the rail plates 4 and 5 so as to be movable up and down, and a block part 13 fixed to the front surface of the lower end part of the base part 11. 13 is integrally fixed to the base portion 11 with bolts 16. A pair of upper and lower pulleys 14 are attached to both side portions of the base portion 11, and these movable pulleys 10 roll along the guide rails 4 a and 5 a of the rail plates 4 and 5, so that the movable portion 10 is the main body 1. It is guided to move up and down almost without any resistance. The front surface of the block portion 13 is formed at the same height in the front-rear direction as the front surface of the front plate 6, and a second fixing portion 15 made of an adhesive rubber sheet is provided on the upper front surface of the block portion 13. . Therefore, the 1st fixing | fixed part 8 and the 2nd fixing | fixed part 15 respond | correspond up and down, and are arrange | positioned at the same height in the front-back direction. An upper end portion of the base portion 11 protrudes upward from the upper surface of the main body 1 and constitutes an operation portion 12. The operation unit 12 is provided at a site opposite to the second fixing unit 15 with the first fixing unit 8 interposed therebetween. Therefore, when the operation unit 12 is pushed down, the second fixing unit 15 moves downward with respect to the first fixing unit 8, that is, the second fixing unit 15 moves in the separation direction with respect to the first fixing unit 8.

ここで、上記構成よりなる強度測定用治具Ａによる試験片Ｂの引張り強度測定方法について、図６を参照して説明する。ここでは、試験片Ｂとして、乾燥済み（未焼成）のセラミックグリーンシートを用いた。
まず、可動部１０の操作部１２を引き上げ、第１固定部８と第２固定部１５とを近接させる。そして、近接した第１固定部８と第２固定部１５との間に跨がって、試験片Ｂを貼り付ける。このとき、試験片Ｂは粘着性を持つラバーシートよりなる第１固定部８と第２固定部１５に安定して貼り付けられる。さらに、その上から、粘着テープ２０を試験片Ｂの上端部と第１固定部８との間、および試験片Ｂの下端部と第２固定部２８との間に貼り付けることで、試験片Ｂの上下端部を固定する（図６参照）。
次に、本体１から突出した操作部１２の上面に押込式強度試験機３０の押し込み部３１を押し当て、下方への荷重を印加する。下方への荷重は第２固定部１５に伝達され、試験片Ｂの下端部を下方へ引っ張る。つまり、強度試験機３０の押し込み方向の力を、試験片Ｂの引張り力に変換している。試験片Ｂの伸びあるいは破断時の荷重を測定することで、試験片Ｂの弾性係数や引張り強度を測定することができる。
試験片Ｂに作用する引張り力Ｆｓと、強度試験機３０の押し込み力Ｆｐとの間には、次の関係式が成立する。
Ｆｓ＝Ｆｐ＋Ｗ−Ｆｒ ・・・（１）
上式において、Ｗは可動部の重量、Ｆｒは摩擦力である。摩擦力Ｆｒは、滑車１４を用いることで、ほぼ零にすることができる。 Here, a method for measuring the tensile strength of the test piece B using the strength measuring jig A having the above configuration will be described with reference to FIG. Here, as the test piece B, a dried (unfired) ceramic green sheet was used.
First, the operation unit 12 of the movable unit 10 is pulled up to bring the first fixed unit 8 and the second fixed unit 15 close to each other. And the test piece B is affixed across the 1st fixing | fixed part 8 and the 2nd fixing | fixed part 15 which adjoined. At this time, the test piece B is stably affixed to the 1st fixing | fixed part 8 and the 2nd fixing | fixed part 15 which consist of an adhesive rubber sheet. Furthermore, by sticking the adhesive tape 20 between the upper end part of the test piece B and the first fixing part 8 and between the lower end part of the test piece B and the second fixing part 28 from above, the test piece. The upper and lower ends of B are fixed (see FIG. 6).
Next, the pushing portion 31 of the pushing type strength tester 30 is pressed against the upper surface of the operation portion 12 protruding from the main body 1, and a downward load is applied. The downward load is transmitted to the second fixing portion 15 and pulls the lower end portion of the test piece B downward. That is, the force in the pushing direction of the strength tester 30 is converted into the tensile force of the test piece B. By measuring the elongation or breakage of the test piece B, the elastic modulus and tensile strength of the test piece B can be measured.
The following relational expression is established between the tensile force Fs acting on the test piece B and the pushing force Fp of the strength tester 30.
Fs = Fp + W−Fr (1)
In the above equation, W is the weight of the movable part, and Fr is the frictional force. The frictional force Fr can be made substantially zero by using the pulley 14.

上記説明では、本体１を静止したステージ上に載置し、上方から試験機３０の押し込み部３１で操作部１２を下方へ押し込む方式について説明したが、この方式に限定されるものではなく、例えば、試験機３０の押し込み部３１を操作部１２の上方の一定位置に配置し、本体１を載置しているステージを上昇させることで、操作部１２を押し込み部３１に押し当てて強度を測定する方式でもよい。要するに、押込式強度試験機とは、ステージと押し込み部との距離を近づけることで強度を測定するものをいう。 In the above description, the system in which the main body 1 is placed on a stationary stage and the operation unit 12 is pushed downward by the pushing unit 31 of the testing machine 30 from above is described. However, the present invention is not limited to this method. The pusher 31 of the testing machine 30 is placed at a fixed position above the operation unit 12 and the stage on which the main body 1 is placed is raised to press the operation unit 12 against the pusher 31 and measure the strength. It may be a method to do. In short, the indentation type strength tester means an instrument that measures strength by reducing the distance between the stage and the indentation part.

図６では、測定前に第１固定部８と第２固定部１５とをほぼ接触する位置まで近接させたが、測定初期位置における第１固定部８と第２固定部１５との間隔、つまり試験片Ｂの初期長さは、第１固定部８と第２固定部１５との最大ストロークＳ（図３参照）の範囲内で任意に設定可能である。
また、第１固定部８と第２固定部１５とに試験片Ｂの両端部を固定する際、強度測定用治具Ａを水平に横倒させ、この状態で試験片Ｂの両端部を第１固定部８と第２固定部１５とに固定すれば、可動部１０の落下を止めておく必要がなく、作業が容易になる。
さらに、引張り強度試験を、強度測定用治具Ａを水平に横倒させた状態で実施すれば、可動部１０の重量Ｗが試験片Ｂに作用しないので、（１）式における可動部の重量Ｗを無視することができる。 In FIG. 6, the first fixing portion 8 and the second fixing portion 15 are brought close to a position where they substantially contact before measurement, but the distance between the first fixing portion 8 and the second fixing portion 15 at the initial measurement position, that is, The initial length of the test piece B can be arbitrarily set within the range of the maximum stroke S (see FIG. 3) between the first fixing portion 8 and the second fixing portion 15.
Further, when both ends of the test piece B are fixed to the first fixing portion 8 and the second fixing portion 15, the strength measuring jig A is horizontally laid down, and in this state, both ends of the test piece B are If it fixes to the 1 fixed part 8 and the 2nd fixed part 15, it is not necessary to stop the fall of the movable part 10, and an operation | work becomes easy.
Furthermore, since the weight W of the movable part 10 does not act on the test piece B if the tensile strength test is carried out with the strength measuring jig A horizontally laid down, the weight of the movable part in the equation (1) W can be ignored.

上記実施形態では、可動部を上下動自在にガイドするために、可動部に滑車を取り付けたが、滑車に代えて転動自在なボールを配置してもよい。このボールがガイドレールに沿って転動することで、可動部を上下動自在にガイドできる。
また、試験片Ｂの両端部を第１の固定部および第２の固定部に固定する方法として、粘着性のラバーシートと粘着テープとを用いたが、これに限るものではなく、接着剤を用いて固定してもよいし、特許文献１に記載のようなクランプ手段を用いてもよく、試験片Ｂの特性に応じて任意に選択できる。
上記実施形態では、本体１を構成する背面板３とレール板４，５と前面板６とを別体で形成し、これらをボルト７などで固定したが、これら部材を一体部品で構成することも可能である。同様に、可動部１０を構成するベース部１１とブロック部１２とを別体で構成したが、一体部品で構成してもよいことは勿論である。
上記実施形態では、操作部１２を第１固定部８を間にして第２固定部１５と反対側の部位に設けたが、操作部１２は本体１から外部へ突出しており、操作部１２を押し込むことで第２固定部１５を第１固定部８に対して離間方向に移動させるものであれば、その突出位置および突出方向は限定されない。
なお、本発明の強度測定用治具は、セラミックグリーンシートに限らず、樹脂フィルムなどシート状の試験片の引張り強度を測定するのに好適であり、さらには、シート状に限らず繊維質材などの引張り強度測定に用いることもできる。 In the above embodiment, a pulley is attached to the movable part in order to guide the movable part up and down, but a rollable ball may be arranged instead of the pulley. By rolling the ball along the guide rail, the movable portion can be guided to move up and down.
Moreover, although the adhesive rubber sheet and the adhesive tape were used as a method of fixing the both ends of the test piece B to the first fixing part and the second fixing part, the present invention is not limited to this. It may be used and fixed, or a clamping means as described in Patent Document 1 may be used, and can be arbitrarily selected according to the characteristics of the test piece B.
In the above embodiment, the back plate 3, the rail plates 4, 5 and the front plate 6 constituting the main body 1 are formed separately and fixed with bolts 7, etc., but these members are configured as an integral part. Is also possible. Similarly, although the base part 11 and the block part 12 which comprise the movable part 10 were comprised by the different body, of course, you may comprise by an integral component.
In the above embodiment, the operation unit 12 is provided on the opposite side of the second fixing unit 15 with the first fixing unit 8 interposed therebetween. However, the operation unit 12 protrudes from the main body 1 to the outside. If it pushes and the 2nd fixing | fixed part 15 is moved to a separation direction with respect to the 1st fixing | fixed part 8, the protrusion position and protrusion direction will not be limited.
The strength measuring jig of the present invention is not limited to a ceramic green sheet, and is suitable for measuring the tensile strength of a sheet-like test piece such as a resin film. It can also be used for tensile strength measurement.
