1 year) As shown on page 55 (see Figure 9), a ceramic member (
Hereinafter, the test piece (hereinafter simply referred to as a test piece) is placed, and a load is applied under high temperature to provide a bending strength L6.
A jig 8 containing a test piece inside is placed so as to hold the test piece 6A.
回転テーブル６の下方にはリフト９が配置されておシ、
リフト９の先端部は回転テーブル６の貫通孔６Ａを貫通

いる。A lift 9 is arranged below the rotary table 6.
The tip of the lift 9 penetrates through the through hole 6A of the rotary table 6 and engages with the jig 8, so that the jig 8 can be moved in and out of the furnace 4 through the opening 4A formed in the furnace 4. It looks like this.

４に形成された試験片１Ｂ移動防止用の溝である。As shown in FIGS. 10 to 11, the jig 8 includes a mounting table 12 on which a test piece is placed, an upper lid 14 assembled to the mounting table 12 so as to surround the upper end surface of the mounting table, and an upper lid 14. It mainly consists of an auxiliary ring 16 for ensuring the engagement of the M14 with the mounting table 12. Two parallel grooves 12 are formed on the upper end surface of the mounting table 12, and a bottle 15 is disposed in this groove. It stands out. On the other hand, two grooves 14A are formed in the upper lid 14 and extend parallel to each other in the same direction as the groove 12A of the mounting table 12, and a bottle 15 is disposed in this groove. It protrudes downward from. Then, test specimens are held between the bins 15 and 15 so as to be perpendicular to the bins, and these -
A vertical load is applied to the test piece 18 through the tubes 15 and 15. Note that the code 14B is the upper lid 1.
4 is a groove for preventing movement of the test piece 1B.

外へ出し入れすることによって行われる。In addition, in the bending test, the lift 9 is raised one level so as to pass through the hole 6A of the table 6, the jig 8 is positioned in the electric furnace 4, a load is applied under high temperature, and after the test piece is broken, the lift 9 is lifted up. Lower the jig 9 and place the jig 8 on the table 6 again.
This is done by sequentially moving the jigs 8 in and out of the furnace 4 one by one, such as rotating the table 6 and positioning the next jig 8 in the electric furnace 4.
前記したように、セラミックス部材曲げ試験機用の供試
体収納治具は、供試体である試験片１８の外周囲全体を
覆うような構造である為、治具が大型となυ、その結果
曲げ試験機全体が治具の大きさにあわせて大型化すると
いう欠点があった。As mentioned above, the specimen storage jig for the ceramic member bending tester has a structure that covers the entire outer periphery of the test piece 18, which is the specimen, so the jig is large υ, resulting in bending. The drawback was that the entire testing machine became larger to match the size of the jig.
また、電気炉４内は１０００〜１５００℃の”高温下に
保持される必要があるが、治具８が大型であるがゆえに
、電気炉に設けられる治具出し入れの為の開口部４Ａが
それだけ大きくなり、この開口部４ムを通じて熱かにげ
やすく消費熱量の無駄が多いという問題点もあった。Furthermore, the inside of the electric furnace 4 needs to be maintained at a high temperature of 1000 to 1500°C, but since the jig 8 is large, the opening 4A provided in the electric furnace for taking in and taking out the jig is only large enough. Due to the large size, there is a problem in that heat is easily dissipated through the opening 4m, resulting in a large amount of wasted heat.
さらにまた、この開口部４Ａが大きい為、電気炉４内の
温度変化が著しく、電気炉４内の温度制御がむずかしい
という問題点もあった。Furthermore, since the opening 4A is large, there is a problem in that the temperature inside the electric furnace 4 changes significantly, making it difficult to control the temperature inside the electric furnace 4.
さらにまた試験片１日に負荷を与えて試験片１日が折損
した後はできるだけ早く電気炉４外へ治具８を取υ出し
、次の治具８を電気炉４内に位置させることが望ましい
が、治具８は大型である上に肉厚に形成されている為、
充分に冷却するまで待つことなく炉外へ取シ出すと、熱
応力によシひび割れが生じるので、熱応力による影響が
なくなる温度に下がる迄治具８を炉外へ取シ出すことが
できず、作業性が非常に悪いという問題点もあった。Furthermore, after applying a load to the test piece 1 and breaking the test piece 1, the jig 8 should be taken out of the electric furnace 4 as soon as possible and the next jig 8 should be placed inside the electric furnace 4. Although this is desirable, since the jig 8 is large and thick,
If the jig 8 is taken out of the furnace without waiting until it has cooled sufficiently, cracks will occur due to thermal stress, so the jig 8 cannot be taken out of the furnace until the temperature has dropped to a point where the influence of thermal stress is eliminated. However, there was also the problem that the workability was very poor.
本発明は前記従来技術の問題点に鑑みなされたもので、

治具を提供することにある。The present invention has been made in view of the problems of the prior art,
The object of the present invention is to provide a specimen storage jig for a ceramic member bending tester that has a compact and simple structure and can improve workability.

ものである。- [Means for Solving the Problems] As a means for solving the above-mentioned problems, the specimen storage jig according to the present invention is a box shaped with a recessed portion capable of storing ceramic specimens from above. The bottom of the box body is characterized by being formed with a notch for arranging a fulcrum member that opens in the recess and extends in a direction perpendicular to the longitudinal direction of the box body, and with this configuration, the above object is achieved. This is what we aim to achieve.
供試体である試験片に負荷が誓与されて、破壊に至シ、
折損したとしても試験片は治具の凹部内に収容されてい
るので、その破片が治具外に飛散することはない。A load is applied to the test piece, which leads to destruction.
Even if the test piece breaks, the pieces are not scattered outside the jig because the test piece is housed in the recess of the jig.

薄肉であるが為、短時間の内に加熱及び冷却されうるも
のであり、電気炉の温度調節に与える影響はわずかで、
さらに連続した曲げ試験の作業性を著しく高めることが
できる。Since the jig according to the present invention is constituted by a single box that opens upward, it has a small and simple structure, and it is very easy to store and take out a specimen from the jig. Furthermore, since the box body is thin, even if it is taken out of the electric furnace, the thermal stress generated in the thick part of the jig is small, and there is no fear that the jig will be destroyed by thermal stress. In addition, since the jig is small and thin, it can be heated and cooled within a short time, so it has only a small effect on the temperature control of the electric furnace.
Furthermore, the workability of continuous bending tests can be significantly improved.
