Description

本考案は、プラグにおける頭部座面とねじ部との間に形成された小径の首部にＯリングを圧入するＯリングのプラグへの圧入装置に関するものである。  The present invention relates to an O-ring press-fitting device for plugging an O-ring into a small-diameter neck formed between a head seating surface and a threaded portion of the plug.

本考案は、主として自動車のエンジン内に溜まる水を水抜きするため、或いはオイル又は冷却水などを交換するためにオイルパンなどの収容体に設けられる詰栓用のプラグへのＯリングの圧入装置に関するものである。  The present invention mainly relates to a device for press-fitting an O-ring into a plug for plugs provided in a container such as an oil pan in order to drain water accumulated in an engine of an automobile or to replace oil or cooling water. It is about.

従来、たとえば、頭部を有し、頭部の下端にオイルパンなどの収容体における排出口のねじ孔に螺合可能なねじ部を設けてなるプラグにあっては、図１１に示すようにプラグＰにおける頭部Ｐ１の座面とねじ部Ｐ２との間に小径首部Ｐ３が形成され、この小径首部Ｐ３にＯリングＲが圧入により装着されている。  Conventionally, for example, in a plug having a head and provided with a screw portion that can be screwed into a screw hole of a discharge port in a container such as an oil pan at the lower end of the head, as shown in FIG. A small-diameter neck portion P3 is formed between the seating surface of the head portion P1 in the plug P and the screw portion P2, and an O-ring R is attached to the small-diameter neck portion P3 by press-fitting.

ところで、上記したＯリングＲをプラグＰに圧入して装着する作業は、機械による自動化が進んでおらず、手作業により行われている。つまり、ＯリングＲは弾性を有し、かつ捩れやすいことから、たとえば機械で自動化してＯリングＲをねじ部Ｐ２の先端側から押入部材により小径首部Ｐ３に圧入しようとすると、ＯリングＲが多少拡径しながらねじ部Ｐ３を通過する際に捩れが生じたり、ねじ部Ｐ３に引っかかって傷ついたりするおそれがある。そのため、機械で自動化するのが困難であるとされ、手作業により行われているのが現状である。その結果、能率の悪い手作業を必要とし、コスト高となる問題を有していた。  By the way, the above-described operation for press-fitting the O-ring R into the plug P is not performed by a machine, but is performed manually. In other words, since the O-ring R has elasticity and is easily twisted, for example, when the O-ring R is to be press-fitted into the small-diameter neck P3 by a pressing member from the tip end side of the threaded portion P2 by automation by a machine, the O-ring R There is a risk of twisting when passing through the threaded portion P3 while slightly expanding the diameter, or being caught by the threaded portion P3 and being damaged. For this reason, it is difficult to automate with a machine, and the current situation is that it is performed manually. As a result, there is a problem in that it requires an inefficient manual operation and increases the cost.

そこで、本考案は、Ｏリングを傷めたり、捩れたりすることがなく、機械による自動化により効率よくＯリングのプラグへの圧入作業を行うことのできるＯリングのプラグへの圧入装置の提供を課題とする。  Therefore, the present invention provides a press-fitting device for an O-ring plug that can efficiently press-fit the O-ring into the plug without being damaged or twisted by the automation of the machine.

Only the press-fitting cylinder 51 is raised. In FIG. 1, reference numeral 55 denotes a support member for the press-fitting mechanism 5.

次に、以上のように構成したＯリングのプラグへの圧入装置の作用について説明する。  Next, the operation of the press-fitting device into the plug of the O-ring configured as described above will be described.

まず、直線フィーダー２はＯリングＲの受取位置にてシューター等から送られてくるＯリングＲを保持孔２１ａ内に１個受け取り、直線フィーダー２を往動してＯリングＲを供給位置に位置させる。このとき、供給位置の真下には予めチャック搬送機構３のチャック爪３１，３１にて挟持された円錐ガイド体１が待機している。そして、図２に示すように、この供給位置にて直線フィーダー２の下板２２のみを後退させて保持孔２１ａの下面を開きＯリングＲを円錐ガイド体１に向かって落下させ、円錐ガイド体１における円錐テーパ面１ａの中間部にＯリングＲを挿入させ受け渡しする。その後、直線フィーダー２は、復動して元の受取位置に戻る。  First, the linear feeder 2 receives one O-ring R sent from a shooter or the like at the receiving position of the O-ring R into the holding hole 21a, and moves the linear feeder 2 forward to position the O-ring R at the supply position. Let At this time, the conical guide body 1 held in advance by the chuck claws 31 of the chuck transport mechanism 3 is waiting just below the supply position. Then, as shown in FIG. 2, only the lower plate 22 of the linear feeder 2 is retracted at this supply position to open the lower surface of the holding hole 21a, and the O-ring R is dropped toward the conical guide body 1 to thereby reduce the conical guide body. The O-ring R is inserted into the intermediate portion of the conical taper surface 1a in 1 and delivered. Thereafter, the linear feeder 2 moves backward and returns to the original receiving position.

次に、図５に示すようにチャック搬送機構３の前後シリンダー３４により円錐ガイド体１を前進させて円錐ガイド体１をプラグＰが待機するターンテーブル４の圧入位置Ｂの真上に搬送する。その後、図６に示すように昇降シリンダー３３により円錐ガイド体１を下降させて円錐ガイド体１をプラグＰのねじ部Ｐ２に被嵌する。このとき、円錐ガイド体１の嵌合穴部１ｂとねじ部Ｐ２との寸法的な嵌め合い関係で小径首部Ｐ３の寸法分だけ隙間が残ることになる。被嵌後、図６の仮想線で示すようにチャック爪３１，３１を開いて円錐ガイド体１をねじ部Ｐ２に残し、かつ、チャック爪３１，３１を開いたままチャック爪３１，３１、つまりチャック搬送機構３を前後シリンダー３４により後退させて退避位置に待機させる。  Next, as shown in FIG. 5, the conical guide body 1 is advanced by the front and rear cylinders 34 of the chuck transport mechanism 3, and the conical guide body 1 is transported directly above the press-fitting position B of the turntable 4 where the plug P stands by. Thereafter, as shown in FIG. 6, the conical guide body 1 is lowered by the elevating cylinder 33, and the conical guide body 1 is fitted on the screw portion P <b> 2 of the plug P. At this time, a gap is left by the dimension of the small-diameter neck portion P3 due to the dimensional fitting relationship between the fitting hole portion 1b of the conical guide body 1 and the screw portion P2. After the fitting, as shown by the phantom lines in FIG. 6, the chuck claws 31, 31 are opened to leave the conical guide body 1 on the threaded portion P2, and the chuck claws 31, 31, that is, with the chuck claws 31, 31 open, that is, The chuck transport mechanism 3 is retracted by the front and rear cylinders 34 and is put on standby at the retracted position.

その退避状態で、図７に示すように圧入装置５の圧入シリンダー５２により圧入筒５１を下降させ、図８に示すように圧入筒５１によりＯリングＲを円錐ガイド体１の円錐テーパ面１ａに沿って拡径させながら下降させ、プラグＰの小径首部Ｐ３にＯリングを圧入させる。  In the retracted state, the press-fitting cylinder 51 is lowered by the press-fitting cylinder 52 of the press-fitting device 5 as shown in FIG. 7, and the O-ring R is moved to the conical tapered surface 1a of the conical guide body 1 by the press-fitting cylinder 51 as shown in FIG. The O-ring is press-fitted into the small-diameter neck P3 of the plug P while being lowered while expanding the diameter.

その圧入後、図９に示すように圧入シリンダー５２による圧入筒５１の上昇により圧入筒５１を円錐ガイド体１から外す。このとき、圧縮されたバネ５３による蹴り出しピン５４の蹴り出し作用により円錐ガイド体１を蹴り出しながら後退することにより円錐ガイド体１をねじ部Ｐ２に確実に残して後退する。  After the press-fitting, the press-fitting cylinder 51 is removed from the conical guide body 1 by raising the press-fitting cylinder 51 by the press-fitting cylinder 52 as shown in FIG. At this time, the conical guide body 1 is moved backward while kicking out the conical guide body 1 by the kicking-out action of the kick-out pin 54 by the compressed spring 53, so that the conical guide body 1 is reliably left behind in the screw portion P2.

その後、図９の仮想線で示すようにチャック爪３１，３１、つまりチャック搬送機構３を前進シリンダー３４により前進させ、チャック爪３１，３１で円錐ガイド体１の下部を挟持する。そしと、その挟持後、図１０に示すように昇降シリンダー３３により円錐ガイド体１を上昇させて、円錐ガイド体１をねじ部Ｐ２から上方に取り出す。然る後、図１０の仮想線で示すように前後シリンダー３４により円錐ガイド体１を後進させて元の作業開始位置に戻す。また、ＯリングＲが装着されたプラグＰは、図４に示すターンテーブル４の間歇回転により所定角度回転移動し、排出位置Ｃにて排出機構４３により外部に取り出される。また、ターンテーブル４の間歇回転により圧入位置Ｂに次のプラグＰが移送されると共に、プラグＰの送り込み位置Ａにて支持穴４１に新たなプラグＰが送り込まれる。そして、上記した一連のＯリングＲのプラグＰへの圧入動作が繰り返し行われることになる。  Thereafter, as indicated by phantom lines in FIG. 9, the chuck claws 31, 31, that is, the chuck transport mechanism 3 is advanced by the advance cylinder 34, and the lower portions of the conical guide body 1 are clamped by the chuck claws 31, 31. Then, after the clamping, the conical guide body 1 is raised by the elevating cylinder 33 as shown in FIG. 10, and the conical guide body 1 is taken out from the screw portion P2. Thereafter, the conical guide body 1 is moved backward by the front and rear cylinders 34 as shown by the phantom lines in FIG. Further, the plug P to which the O-ring R is attached is rotated by a predetermined angle by intermittent rotation of the turntable 4 shown in FIG. 4 and taken out by the discharge mechanism 43 at the discharge position C. Further, the next plug P is transferred to the press-fitting position B by intermittent rotation of the turntable 4, and a new plug P is sent into the support hole 41 at the plug P feeding position A. Then, the press-fitting operation of the series of O-rings R into the plug P is repeatedly performed.

以上のように、ＯリングＲのプラグＰへの圧入動作が機械により自動的に繰り返し行われるのである。その結果、Ｏリングを傷めたり、捩れたりすることがなく、機械による自動化により効率よくＯリングのプラグへの圧入作業を行うことができる。  As described above, the press-fitting operation of the O-ring R into the plug P is automatically repeated by the machine. As a result, the O-ring is not damaged or twisted, and the press-fitting operation of the O-ring into the plug can be performed efficiently by machine automation.

なお、円錐ガイド体１へのＯリングＲの供給機構２としては、上記したようにＯリングＲを落下させて円錐ガイド体１の先端部に挿入させる他、たとえば、作業開始位置において円錐ガイド体１を上昇させ、作業開始位置上方で待機する供給機構２のＯリングＲの穴部に円錐ガイド体１の先端部を挿入させるようにしてもよい。その場合、円錐ガイド体１にＯリングＲを残して供給機構２を次のＯリングＲの受取位置に後退させる一方、円錐ガイド体１をＯリングＲと共に下降させて作業開始位置に戻すようにすればよい。また、上記した実施の形体では、ターンテーブル４を用いたので、プラグの圧入位置への供給、及び排出をスムーズに間歇的に行えるのでこのましい。なお、保持機構としては、ターンテーブル４の他たとえば直線的にプラグＰの圧入位置への供給、及び排出を行う構成であってもよい。  As the supply mechanism 2 for the O-ring R to the conical guide body 1, as described above, the O-ring R is dropped and inserted into the tip of the conical guide body 1, for example, the conical guide body at the work start position. 1 may be raised, and the tip of the conical guide body 1 may be inserted into the hole of the O-ring R of the supply mechanism 2 that stands by above the work start position. In that case, the O-ring R is left in the conical guide body 1 and the supply mechanism 2 is retracted to the receiving position of the next O-ring R, while the conical guide body 1 is lowered together with the O-ring R to return to the work start position. do it. Further, in the above-described embodiment, since the turntable 4 is used, it is preferable because the plug can be smoothly and intermittently supplied to and discharged from the press-fitting position. In addition, as a holding mechanism, the structure which performs supply to the press-fit position of the plug P other than the turntable 4, for example, and discharge | emission may be sufficient.
