Description
【０００１】[0001]
本考案は、内燃機関のシリンダブロックのシーリング装置に関する。 The present invention relates to a sealing device for a cylinder block of an internal combustion engine.
【０００２】[0002]
一般に、車両の内燃機関のシリンダブロック１１には、図５に示すように種々 の鋳抜孔からなる貫通孔１２が形成されている（例えば、実開平２−１４４６３ ９号公報）。 Generally, a cylinder block 11 of an internal combustion engine of a vehicle is provided with a through hole 12 formed of various cast holes as shown in FIG. 5 (for example, Japanese Utility Model Laid-Open No. 2-144639).
【０００３】 そして、従来、図６に示すように、シリンダブロック１１の水系１３に形成さ れた鋳抜孔からなる貫通孔１４には、椀形プラグ１５が嵌装されている（例えば 、実開昭６４−５３４４４号公報）。Conventionally, as shown in FIG. 6, a bowl-shaped plug 15 is fitted into a through hole 14 formed of a cast hole formed in the water system 13 of the cylinder block 11 (for example, actual opening). JP-A-64-53444).
【０００４】[0004]
然し乍ら、上記図６に示した単なる椀形プラグ１５では、シーリングが確実で ない場合がある。 However, with the mere bowl-shaped plug 15 shown in FIG. 6, the sealing may not be reliable.
【０００５】 本考案は上記に鑑みてなされたもので、シリンダブロックの貫通孔のシーリン グが確実なシリンダブロックのシーリング装置を提供することを目的とする。The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a cylinder block sealing device in which the through hole of the cylinder block is reliably sealed.
【０００６】[0006]
本考案は、シリンダブロックの水系及びオイル系に形成された貫通孔をシール するシリンダブロックのシーリング装置において、上記貫通孔に椀形プラグを嵌 装し、その椀形プラグの円筒内面にテーパ面を有するプラグを介装したことを特 徴とする。 The present invention is a sealing device for a cylinder block that seals through-holes formed in a water system and an oil system of a cylinder block, in which a bowl-shaped plug is fitted in the through-hole, and a tapered surface is formed on the inner surface of the cylinder of the bowl-shaped plug. The feature is that it has a plug.
【０００７】[0007]
上記貫通孔に椀形プラグを嵌装した後、その椀形プラグ内にテーパ面を有する プラグを介装すれば、椀形プラグが外周方向に広げられて、貫通孔に密着する。 If a bowl-shaped plug is fitted in the through hole and then a plug having a tapered surface is interposed in the bowl-shaped plug, the bowl-shaped plug is expanded in the outer peripheral direction and comes into close contact with the through hole.
【０００８】 従って、シリンダブロックの貫通孔のシーリングが確実になる。Therefore, the sealing of the through hole of the cylinder block becomes reliable.
【０００９】[0009]
以下、本考案を図に基づいて詳細に説明する。 図１及び図２は、本考案のシーリング装置の一実施例を示したものである。 Hereinafter, the present invention will be described in detail with reference to the drawings. 1 and 2 show an embodiment of the sealing device of the present invention.
【００１０】 図において、１は例えば、車両の内燃機関のシリンダブロックで、その水系及 びオイル系に鋳抜孔からなる貫通孔２形成されている。 本考案は、この貫通孔２に、椀形プラグ３を嵌装し、その椀形プラグ３の円筒 内面４にテーパ面５を有するプラグ６を介装したものである。In the figure, reference numeral 1 denotes, for example, a cylinder block of an internal combustion engine of a vehicle, in which a through hole 2 formed of a cast hole is formed in its water system and oil system. In the present invention, a bowl-shaped plug 3 is fitted in the through hole 2, and a plug 6 having a tapered surface 5 on the inner surface 4 of the bowl of the bowl-shaped plug 3 is interposed.
【００１１】 貫通孔２の内径Ｄａと椀形プラグ３の先端外径Ｄｂと椀形プラグ３の円筒内面 ４の内径Ｄｃとプラグ６の後端外径Ｄｄとの関係は、Ｄａ＞Ｄｂ，Ｄｃ＜Ｄｄ， Ｄａ＞Ｄｄになっている。The relationship between the inner diameter Da of the through hole 2, the tip outer diameter Db of the bowl-shaped plug 3, the inner diameter Dc of the cylindrical inner surface 4 of the bowl-shaped plug 3 and the rear-end outer diameter Dd of the plug 6 is Da> Db, Dc. <Dd, Da> Dd.
【００１２】 従って、図１に示すように、椀形プラグ３が貫通孔２に嵌装され、椀形プラグ ３の円筒内面４にテーパ面５を有するプラグ６が介装されれば、シリンダブロッ ク１の貫通孔２のシーリングが確実になる。Therefore, as shown in FIG. 1, if the bowl-shaped plug 3 is fitted into the through hole 2 and the plug 6 having the tapered surface 5 is provided on the cylindrical inner surface 4 of the bowl-shaped plug 3, the cylinder block 3 is inserted. The sealing of the through hole 2 of the hook 1 becomes reliable.
【００１３】 尚、テーパ面５を有するプラグ６が容易に椀形プラグ３の円筒内面４に介装さ れるように、円筒内面４の端７を面取りしてある。 貫通孔２への椀形プラグ３及び椀形プラグ３へのプラグ６の装着は、図３に示 すように、初めに貫通孔２へ椀形プラグ３を嵌装し、次に椀形プラグ３の円筒内 面４にテーパ面５を有するプラグ６を介装し、その後、図４に示すように貫通孔 ２の内側からストッパ８で椀形プラグ３を保持し、貫通孔２の外側から治具棒９ を槌１０で打ち付けるようにして椀形プラグ３の円筒内面４内へテーパ面５を有 するプラグ６を介装することにより行われる。The end 7 of the cylindrical inner surface 4 is chamfered so that the plug 6 having the tapered surface 5 can be easily inserted into the cylindrical inner surface 4 of the bowl-shaped plug 3. As shown in FIG. 3, the bowl-shaped plug 3 and the bowl-shaped plug 3 are attached to the through-hole 2 by first fitting the bowl-shaped plug 3 into the through-hole 2 and then the bowl-shaped plug. 3, a plug 6 having a tapered surface 5 is interposed on the inner surface 4 of the cylinder, and then the bowl-shaped plug 3 is held by a stopper 8 from the inside of the through hole 2 as shown in FIG. The jig rod 9 is struck with a mallet 10 and the plug 6 having the tapered surface 5 is inserted into the cylindrical inner surface 4 of the bowl-shaped plug 3.
【００１４】[0014]
以上説明したように本考案よれば、テーパ面を有するプラグにより椀形プラグ が外周方向に広げられるため、シリンダブロックの貫通孔のシーリングが確実に なる。 As described above, according to the present invention, since the bowl-shaped plug is expanded in the outer peripheral direction by the plug having the tapered surface, the sealing of the through hole of the cylinder block is ensured.
