本考案は材料試験機の曲げ試験用加圧片の改良
に関するものである。[Detailed Description of the Invention] The present invention relates to an improvement of a pressure piece for bending tests of a material testing machine.
第１図及び第２図は材料試験機を用いて曲げ試
験を行なつている様子を示すものである。１は受
け台であつて、支承片２，３を備えている。支承
片２，３は矢印Ａ，Ｂで示すように、互に逆向き
に移動することができ、その間隔は目盛４で表示
される。５は加圧片であつて、ホルダー６を介し
て加圧腕７に取付けられる。 Figures 1 and 2 show how a bending test is performed using a material testing machine. Reference numeral 1 denotes a cradle, which is provided with supporting pieces 2 and 3. The bearing pieces 2, 3 can be moved in opposite directions, as shown by arrows A and B, and the distance between them is indicated by a scale 4. Reference numeral 5 denotes a pressure piece, which is attached to the pressure arm 7 via a holder 6.
S1は板状の試験片であつて、支承片２，３上に
載置される。支承片２，３はその傾斜した上面の
内側の縁で試験片S1を２本の線で支承する。この
支承縁は正確に平行に仕上げてある。加圧片５
は、加圧腕７の下降により試験片S1の上面に接触
し、それを加圧して曲げ歪を与える。加圧片５の
下縁は前記支承片２，３の支承縁と互に平行でな
ければならない。さもないと、試験片S1の全巾に
亘つて均等な曲げ歪を与えることはできない。 S1 is a plate-shaped test piece, and is placed on the support pieces 2 and 3. The bearing pieces 2, 3 support the specimen S 1 in two lines at the inner edges of their inclined upper surfaces. The bearing edges are precisely parallel. Pressure piece 5
comes into contact with the upper surface of the test piece S1 by lowering the pressurizing arm 7, pressurizes it, and applies bending strain. The lower edge of the pressure piece 5 must be parallel to the bearing edges of the bearing pieces 2 and 3. Otherwise, uniform bending strain cannot be applied over the entire width of the test piece S1 .
前記の平行精度を出すために、加圧片５は第３
図に示すようにピン８によつてホルダー６に枢支
されている。すなわち、加圧片５はピン８を中心
として矢印Ｃで示すように回動することができ
る。その結果、加圧片５の下縁が支承片２，３の
支承縁と平行でなくても、試験片S1に接触するこ
とにより自動的に回動して平行となる。 In order to achieve the above-mentioned parallel accuracy, the pressure piece 5 is
As shown in the figure, it is pivotally supported on the holder 6 by a pin 8. That is, the pressure piece 5 can rotate as shown by arrow C around the pin 8. As a result, even if the lower edge of the pressure piece 5 is not parallel to the bearing edges of the bearing pieces 2 and 3, it automatically rotates and becomes parallel when it comes into contact with the test piece S1 .
ところで、前記試験機によつて、丸棒の如き回
転体の曲げ試験を行なうと不都合が生じる。第３
図に示すように、丸棒の試験片S2を加圧片５によ
つて加圧すると、加圧片５が矢印Ｃ方向に回動す
るため、試験片S2を側方に向けて加圧する結果、
試験片S2が移動し、それに荷重を与えることがで
きない。 By the way, when a bending test is performed on a rotating body such as a round bar using the above-mentioned testing machine, an inconvenience occurs. Third
As shown in the figure, when the round bar test piece S 2 is pressed by the pressure piece 5, the pressure piece 5 rotates in the direction of arrow C, so the test piece S 2 is applied sideways. As a result of pressure,
Specimen S 2 moves and no load can be applied to it.
本考案は、前記のような可動型の加圧片５を用
いるものにおいても、回転体の曲げ試験ができる
ようにすることを目的とするものであつて、第４
図以下はその実施例を示すものである。 The purpose of the present invention is to enable a bending test of a rotating body even in a device using the movable pressure piece 5 as described above.
The figures below show examples.
加圧片５の両側面には第４図(a)に示すようにね
じ孔９を明け、それを利用して固定片１０ａ，１
０ｂを第５図，６図に示すようにボルト１１で固
定する。 As shown in FIG. 4(a), screw holes 9 are provided on both sides of the pressure piece 5, and the fixing pieces 10a, 1 are screwed using the screw holes 9.
0b is fixed with bolts 11 as shown in FIGS. 5 and 6.
回転体の試験片S2に対して、加圧片５で荷重を
与えるに際し、加圧片５に作用する矢印Ｃ方向の
回転力は加圧片５の両側面に固着した固定片１０
ａ，１０ｂが、ホルダー６に当接するため受け止
められ、加圧片５は回動しない。したがつて、試
験片S2は移動することなく、荷重を受けることが
できる。 When the pressure piece 5 applies a load to the test piece S 2 of the rotating body, the rotational force acting on the pressure piece 5 in the direction of arrow C is applied to the fixed piece 10 fixed to both sides of the pressure piece 5.
a and 10b are received by the holder 6 as they come into contact with the holder 6, and the pressure piece 5 does not rotate. Therefore, the test piece S2 can receive a load without moving.
固定片１０ａ，１０ｂはボルト１１を緩めるこ
とにより外すことができるので、加圧片５は可動
型としても固定型としても利用することができ
る。 Since the fixed pieces 10a and 10b can be removed by loosening the bolts 11, the pressure piece 5 can be used as either a movable type or a fixed type.
本考案は以上のように、加圧片をホルダーに対
して回動可能に取付け、その回動を阻止する固定
片を着脱自在に設けたので、板状の試験片でも、
回転体の試験片でも適正な曲げ試験を行なうこと
ができる。 As described above, in the present invention, the pressurizing piece is rotatably attached to the holder, and the fixing piece that prevents the rotation is detachably provided, so even a plate-shaped test piece can be
Appropriate bending tests can also be performed on test pieces of rotating bodies.
