Description
【０００１】[0001]
本考案は、自動車用エンジン等におけるコネクティングロッドの疲労試験に用 いられる治具に関する。 The present invention relates to a jig used for a fatigue test of a connecting rod in an automobile engine or the like.
【０００２】[0002]
コネクティングロッドの疲労試験を行うにあたって、従来では、図５に示すよ うに、ピストンに連結する小端部１とクランクシャフトに連結する大端部２との 間で引張り荷重（図中矢印方向参照）をかけて行っていた。 In performing a fatigue test of a connecting rod, conventionally, as shown in FIG. 5, a tensile load is applied between a small end portion 1 connected to a piston and a large end portion 2 connected to a crankshaft (see the arrow direction in the figure). I was going over.
【０００３】[0003]
ところが、上述した試験方法にあっては、荷重の方向が一方向のみであったた め、連桿部３の強度は十分測ることができるが、大端部２の強度は十分には測れ なかった。特に、斜め方向の荷重に対する大端部の強度はあまり試験されていな かった。 However, in the above-mentioned test method, since the load direction is only one direction, the strength of the connecting rod portion 3 can be measured sufficiently, but the strength of the large end portion 2 cannot be measured sufficiently. It was In particular, the strength of the large end against diagonal loads has not been well tested.
【０００４】 そこで、本考案の目的は、通常の疲労試験機を用いて大端部の強度を十分測る ことができるコネクティングロッド疲労試験用治具を提供することにある。Therefore, an object of the present invention is to provide a connecting rod fatigue test jig capable of sufficiently measuring the strength of the large end portion using an ordinary fatigue tester.
【０００５】[0005]
前記目的を達成するため、本考案の構成は、クランクピンに相当する軸部材を 半割し、その内の一方を固定支持軸部として固定部材に架設し、他方を可動支持 軸部として前記固定部材に対設される可動部材に架設し、この可動部材に、疲労 試験機により荷重をかけるための連結部を設けたことを特徴とする。 In order to achieve the above-mentioned object, the structure of the present invention is such that a shaft member corresponding to a crankpin is halved and one of them is erected on a fixed member as a fixed support shaft portion, and the other is fixed as a movable support shaft portion. It is characterized in that it is installed on a movable member opposite to the member, and that this movable member is provided with a connecting portion for applying a load by a fatigue tester.
【０００６】[0006]
前記構成によれば、コネクティングロッドのセット方向を変更することで、大 端部にかかる荷重の方向が任意にセットされる。 According to the above configuration, by changing the setting direction of the connecting rod, the direction of the load applied to the large end can be set arbitrarily.
【０００７】[0007]
以下、本考案の一実施例を添付図面に基づいて説明する。 図１は本治具の正面図で、図２はその側面図である。 An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a front view of the jig, and FIG. 2 is a side view thereof.
【０００８】 図示のように、コ字枠状の固定部材１０と可動部材１１とが、互いの両脚部を 対向させて上下に配設される。As shown in the figure, a U-shaped fixed member 10 and a movable member 11 are arranged vertically with their both legs facing each other.
【０００９】 固定部材１０は基台１２上に適宜の手段で堅固に固定される一方、可動部材１ １はその頂部から突出したボルト１３を介して図示しない既存のサーボパルサー （引張・圧縮疲労試験機）に連結され、図中矢印方向へ荷重がかけられるように なっている。The fixed member 10 is firmly fixed on the base 12 by an appropriate means, while the movable member 11 is fixed to the existing servo pulser (not shown) through a bolt 13 protruding from the top thereof. It is connected to the machine) and the load can be applied in the direction of the arrow in the figure.
【００１０】 そして、クランクシャフトのクランクピン（図示せず）に相当する軸部材が上 下に半割りされて、前記固定，可動両部材１０，１１の両脚部間に、それぞれ固 定支持軸部１４及び可動支持軸部１５として一体的に架設される。A shaft member corresponding to a crank pin (not shown) of the crankshaft is divided into upper and lower halves, and fixed support shaft parts are respectively provided between both leg parts of the fixed and movable members 10 and 11. 14 and the movable support shaft portion 15 are integrally installed.
【００１１】 なお、前記固定，可動両支持軸部１４，１５は固定，可動両部材１０，１１に 対し着脱自在となし、異なる大きさの固定，可動両支持軸部が固定，可動両部材 １０，１１に装着し得るようにしても良い。Both the fixed and movable support shafts 14 and 15 are detachable from the fixed and movable members 10 and 11, and the fixed and movable support shafts of different sizes are fixed and movable. , 11 may be attached.
【００１２】 このように構成されるため、固定，可動両支持軸部１４，１５に、同じく半割 りされた、コネクティングロッドの大端部２を嵌合した後、図３に示すように、 小端部１をジャッキ１６等で上下動させて角度を例えば１５度おきにセットすれ ば、大端部２の強度をあらゆる方向から測定することができる。Due to this structure, after the large end 2 of the connecting rod, which is also split in half, is fitted to both the fixed and movable support shafts 14 and 15, as shown in FIG. If the small end 1 is moved up and down with the jack 16 or the like and the angles are set at intervals of, for example, 15 degrees, the strength of the large end 2 can be measured from any direction.
【００１３】 即ち、図４に示すように、従来見きれていなかった斜め方向の荷重に対する大 端部２の強度が見れるのである。That is, as shown in FIG. 4, the strength of the large end portion 2 against a load in an oblique direction, which has not been noticed conventionally, can be seen.
【００１４】 なお、本考案は、上記実施例に限定されず、本考案の要旨を逸脱しない範囲内 で各種変更が可能であることは言う迄もない。It is needless to say that the present invention is not limited to the above-described embodiment, and various changes can be made without departing from the gist of the present invention.
