【技術分野】
本発明は，被装着部材の装着穴内にリング状の挿入部品を挿入配置するための部品挿入装置に関する。
【０００２】
【従来技術】
例えば，Ａ／Ｔ（オートマチックトランスミッション）などの機械装置においては，多種多様のリング状の部品が使用されている。これらの部品を，被装着部材に設けられた装着穴内に挿入配置する工程では，通常は，圧入が行われるので，その挿入圧力に対応する加圧力発生部とそれを受け止める製品クランプ部とを備えた専用の圧入装置が用いられている。例えば５トンの挿入圧力が必要な工程においては，５トン以上の圧力を発揮しうるアクチュエータを備えると共に，５トン以上の応力を受け止めうる製品クランプ部を備えた専用装置が用いられる。なお，リング状部品の装入装置としては，例えば，特許文献１に記載されたような装置が提案されている。

【０００４】
【解決しようとする課題】
しかしながら，上記従来の専用の圧入装置は，非常に高価であると共に専有面積も広い。そのため，上記従来の圧入装置は，工程変更や仕様変更に対応する配置換えや改造が困難であり，また，多品種の製品に対応するのは難しい。そこで，コンパクトで，かつ，必要な挿入圧力を容易に得ることができる構造を有する安価な部品挿入装置の開発が望まれていた。
【０００５】
本発明は，かかる従来の問題点に鑑みてなされたもので，コンパクトで，かつ，必要な挿入圧力を容易に得ることができる構造を有する安価な部品挿入装置を提供しようとするものである。
【０００６】
【課題の解決手段】
本発明は，装着穴を有する被装着部材の上記装着穴内にリング状の挿入部品を挿入配置するための部品挿入装置であって，
上記挿入部品を保持する部品保持部と，
該部品保持部に保持された上記挿入部品の内部を貫通するよう突出していると共にその外径寸法が上記装着穴の内径寸法よりも小さい先端突出部と，
該先端突出部に配設され，その最大外径が上記装着穴の内径寸法よりも大きくなる拡径状態と，上記内径寸法よりも小さくなる縮径状態との間で状態を変更するよう拡縮可能に設けられた係合爪部と，
上記部品保持部に保持された上記挿入部品を上記係合爪部に相対的に近づくように移動させる部品移動手段とを有していることを特徴とする部品挿入装置にある（請求項１）。
【０００７】
本発明の部品挿入装置は，上記のごとく，上記先端突出部に上記拡縮可能に設けられた係合爪部を配設してある。そのため，上記挿入部品を上記被装着部材の装着穴に挿入する際には，上記係合爪部を利用して，容易に挿入圧力を確保することができる。
【０００８】
即ち，上記部品挿入装置を用いて上記挿入部品を被装着部材に挿入する際には，まず上記部品保持部にリング状の挿入部品を保持させる。次に，上記先端突出部を被装着部材の装着穴に貫通させる。これと共に上記先端突出部における上記係合爪部を拡径状態とする。なお，この拡径状態の実現は，上記係合爪部及びその周辺部分の具体的な構造により実現する方式が相違する（実施例参照）。
【０００９】
次に，上記部品移動手段を操作して，上記挿入部品を上記係合爪部に相対的に近づくように移動させる。これにより，上記被装着部材の装着穴の一方の開口部の周囲の端面には上記係合爪部が当接し，また，他方の開口部には上記挿入部品が対面した状態になる。さらに上記挿入部品を相対的に係合爪部に近づけると，上記係合爪部と挿入部品とによって，被装着部材の装着穴の部分を挟持するような状態になる。さらに上記挿入部品を相対的に係合爪部に近づけると，部品から被装着部材への応力が高まると共に，係合爪部から被装着部材への反力が高まり，挿入部品を近づけようとする応力が直接的に挿入部品の挿入応力となる。
【００１０】
即ち，本発明の部品挿入装置を用いれば，挿入部品を相対的に係合爪部に近づけようとする応力が，無駄なく直接的に挿入応力に利用される。そして，被装着部材を固定する部分からの反力を殆ど作用させる必要がない。そのため，従来の大型の圧入装置のような，挿入圧力を受け止めることができる強固な製品クランプ部を備える必要がない。
【００１１】
また，上記挿入圧力を上記のごとく挟持することによって発生させることができるので，種々のリンク機構の採用や回転動作からの進退動作への変換機構の採用等を容易に行うことができ，小さなトルクで大きな挿入圧力を得ることができる。それ故，本発明の部品挿入装置はコンパクトで安価なものとなる。
【００１２】
このように，本発明によれば，コンパクトで，かつ，必要な挿入圧力を容易に得ることができる構造を有する安価な部品挿入装置を提供することができる。
【００１３】
【発明の実施の形態】
本発明の部品挿入装置においては，上記先端突出部は，筒状の外筒部と，該外筒部の内部において進退可能に配設されたシャフト部とを有しており，上記係合爪部は，上記外筒部の先端近傍に設けられた支点を中心に揺動可能に固定され，上記外筒部の先端を下方に向けて配置した際に自重によって上記拡径状態となるように構成されていると共に，上記シャフト部が前進した際には該シャフト部に当接して上記縮径状態となるよう構成されていることが好ましい（請求項２）。
この場合には，上記係合爪部における上記縮径状態と拡径状態との間の状態変化を上記シャフト部の進退動作によって容易に制御することができる。
【００１４】
また，上記部品移動手段は，上記挿入部品に対面すると共に進退可能に配設された当接部材を有しており，該当接部材を上記部品保持部に保持された上記挿入部品に当接させると共に前進させて上記挿入部品を移動させるよう構成されていることが好ましい（請求項３）。
この場合には，上記部品保持部を固定させた状態で，上記当接部材を移動させることにより挿入部品の移動を行う構成とすることができる。そのため，上記部品保持部は移動可能に設ける必要が無く，その構造を簡単にすることができる。
【００１５】
また，上記先端突出部における上記シャフト部と上記部品移動手段における上記当接部材とは，互いに共通した操作手段に接続されており，該操作手段を第１の方向に操作することによって両者の間隔が小さくなり，第２の方向へ操作することによって両者の間隔が大きくなるよう構成されており，かつ，両者の間隔を小さくする場合には，まず上記シャフト部が所定距離後退した後，上記当接部材が前進するように構成されていることが好ましい（請求項４）。
この場合には，上記共通の操作手段を操作することによって，一つの連続した動作として，上記シャフト部の後退による係合爪部の縮径状態から拡径状態への移行と，係合爪部と当接部材との間の間隔を縮める動作を行うことができる。それ故，非常に操作性に優れたものとなる。
【００１６】
なお，上記シャフト部の後退移動と上記当接部材の前進移動の順序を制御する機構としては，例えば，当接部材の移動を摩擦抵抗等によってある程度妨げておいて，両者が移動可能な場合には，シャフト部が優先的に移動し，また，シャフト部の移動が規制された後には上記当接部材のみを移動させるように構成することができる。
また，上記シャフト部の移動の規制は，例えば，上記先端突出部における外筒部に対するシャフト部の相対的な移動領域を制限することによって，シャフト部が所定距離後退した後はシャフト部と外筒部とが一体的に後退し，これにより外筒部が有する上記係合爪部が被装着部材に当接して外筒部及びシャフト部のそれ以上の移動を阻止することにより行うことができる。
【００１７】
また，上記操作手段は，ベース部と，該ベース部に対して回動可能に支持された操作アーム部と，上記ベース部に対してスライド可能に配設されたポール部と，上記操作アーム部と上記ポール部の両者に回動支点をそれぞれ有するリンク部材とよりなり，上記シャフト部又は上記当接部材のいずれか一方に上記ベース部が接合され，他方に上記ポール部が接合されていることが好ましい（請求項５）。
【００１８】
この場合には，上記操作アーム部の一方向への操作によって，上述した一連の動作，即ち，シャフト部の後退による係合爪部の縮径状態から拡径状態への移行及び当接部材の前進を容易に実現することができる。さらに，上記操作アーム部の逆方向への操作によって，当接部材の後退及びシャフト部前進による係合爪部の拡径状態から縮径状態への移行を容易に実現することができる。
また，上記操作アーム部に作用する力を所謂てこの原理によって増大させて上記シャフト部及び上記当接部材に付与することができ，大きな挿入圧力を容易に得ることができる。
【００１９】
また，上記挿入部品は，上記被装着部材の上記装着穴の内周面に設けられたリング溝に挿入配置されるスナップリングを含んでおり，上記部品保持部は，該スナップリングの自由外径よりも小さい内径を有するスナップリング保持部を備えており，該スナップリング保持部の内壁面に縮径させた上記スナップリングの外周面を当接させることにより，その拡開力によって該スナップリングを保持するよう構成されていることが好ましい（請求項６）。
【００２０】
この場合には，比較的挿入作業が困難なスナップリングの挿入を，上記部品挿入装置を用いることによって容易に行うことができる。特に，上記スナップリング保持部にスナップリングを保持させた状態で当接部材を移動させる構成を採用することによって，上記スナップリングの保持と移動を容易かつ安定的に行うことができる。
【００２１】
また，上記挿入部品は，少なくともその内周面にＯリングを備えたリング部品を含んでおり，上記部品保持部は，該リング部品の上記Ｏリングの内径よりも大きい外径を有するリング部品保持部を備えており，該リング部品保持部の外壁面に上記Ｏリングを装着させることにより，該Ｏリングの圧縮力によって上記リング部品を保持するよう構成されていることが好ましい（請求項７）。
この場合には，上記リング部品保持部によって上記リング部品を保持させた状態で当接部材を移動させる構成を採用することによって，上記スナップリングの保持と移動を容易かつ安定的に行うことができる。
【００２２】
なお，上記部品保持部として，上記スナップリング保持部と上記リング部品保持部の両方を備えることもでき，この場合には，スナップリングと上記リング部品の挿入を同時に行うことができる。
【００２３】
次に，本発明の部品挿入装置においては，上記先端突出部は，筒状のシリンダ部と，該シリンダ部の内部において進退可能に配設されたピストン部とを有しており，該ピストン部は，上記シリンダ部内に配設された付勢部材によって，後退する方向に付勢されていると共に，上記シリンダ部内に導入される流体の圧力によって上記付勢部材の付勢力に抗して前進するよう構成されており，上記係合爪部は，上記シリンダ部に設けられた支点を中心に揺動可能に固定されていると共に，その後端部を上記シリンダ部内に配置してあり，上記ピストン部は，上記係合爪部の上記後端部と係合し，該ピストン部が前進又は後退することによって上記係合爪部を上記縮径状態又は上記拡径状態に変化させるよう構成されていることも好ましい（請求項８）。
【００２４】
この場合には，上記係合爪部を上記付勢部材の付勢力によって定常時は常時拡径状態に維持することができる。そのため，上記先端突出部を被装着部材の装着穴に貫通させる際には，係合爪部をその装着穴の内面に押し当てることにより上記付勢力に抗して係合爪部を縮径状態とし，装着穴を抜け出た瞬間に上記付勢力によって即時に拡径状態へと復帰させることができる。そのため，上記先端突出部の装着穴への貫通作業が非常に容易である。
上記付勢部材としては，スプリング，ゴム等の弾性体を用いることができる。
【００２５】
また，先端突出部を上記装着穴から引き抜く際には，上記シリンダ部内に流体を導入することにより，その圧力によってピストン部を前進させる。上記流体としては，空気，作動油等の様々な流体を採用可能であるが，特に，取り扱いが容易な点で空気が最も好ましい。
【００２６】
また，上記部品保持部は，該部品保持部と上記先端突出部との間隔を拡縮できるよう上記先端突出部に対して相対的に進退可能に設けられていることが好ましい（請求項９）。
この場合には，挿入部品を保持した部品保持部全体が進退する。そのため，上述したような部品保持部の他に当接部材を設ける場合よりも，部品点数を減少させることができ，全体をシンプルな構造にすることができる。
【００２７】
また，上記部品保持部は，上記先端突出部に対してスライド可能に配設されていると共に，軸方向に沿って設けられた雌ねじ穴を有しており，該雌ねじ穴にはこれに係合する雄ネジ部を有するスクリュー軸を挿設してあり，上記部品移動手段は，上記スクリュー軸を回動させることによって上記部品保持部を上記先端突出部に対して進退させるよう構成されていることが好ましい（請求項１０）。
この場合には，回転力を挿入部品の挿入圧力に変換するので，小さな回転トルクで容易に大きな挿入圧力を得ることができる。
【００２８】
また，上記部品挿入装置は，種々の工具を着脱可能であると共に装着した上記工具を任意の場所に移動させ回転させることができるよう構成されたマシニングセンタに装着可能であり，該マシニングセンタに装着するためのホルダー部を有すると共に，該ホルダー部の回転動作が上記スクリュー軸に伝わるよう構成されていることが好ましい（請求項１１）。
この場合には，上記マシニングセンタにおける１つの工具として上記部品挿入装置を適用することができ，様々な加工に続く一連の動作の中で上記挿入部品の挿入作業を行うことができ，より一層製造工程の合理化を図ることができる。
【００２９】
【実施例】
実施例１
本発明の実施例に係る部品挿入装置につき，図１〜図７を用いて説明する。
本例の部品挿入装置１は，図１〜図４に示すごとく，装着穴８１０を有する被装着部材８１の装着穴８１０内にリング状の挿入部品９１〜９３を挿入配置するための部品挿入装置である。
【００３０】
部品挿入装置１は，図１に示すごとく，上記挿入部品９１〜９３（図２）を保持する部品保持部１１，１２と，該部品保持部１１，１２に保持された上記挿入部品９１〜９３の内部を貫通するよう突出していると共にその外径寸法が上記装着穴８１０の内径寸法よりも小さい先端突出部２とを有している。
また，部品挿入装置１は，先端突出部２に配設された係合爪部３を有している。係合爪部３は，その最大外径が装着穴８１０の内径寸法よりも大きくなる拡径状態（図５）と，内径寸法よりも小さくなる縮径状態（図１）との間で状態を変更するよう拡縮可能に設けられている。
さらに，部品挿入装置１は，上記部品保持部１１，１２に保持された挿入部品９１〜９３を係合爪部３に相対的に近づくように移動させる部品移動手段５とを有している。
【００３１】
以下，さらに詳説する。
本例における上記被装着部材８１は，図４に示すごとく，Ａ／Ｔ（オートマチックトランスミッション）を構成する部品の一部で，その装着穴８１０として，２種類の部品９２，９３を挿入する挿入穴８１１と，スナップリング９１を挿入するリング溝８１２を有する部材である。
【００３２】
また，図２に示すごとく，第１の挿入部品９１はスナップリングであり，一部に切り欠き部が設けられたリング形状を有し，拡縮可能に構成されている。また，第２の挿入部品９２はリターンスプリング，第３の挿入部品９３はアキュームピストンとそれぞれ呼ばれ，両者の間にスプリング９２５を介して配設される部品である。挿入部品９３は，その内周面及び外周面にシール用のＯリング９３１，９３２が備えられている。
本例の部品挿入装置１は，これら３つの挿入部品９１〜９３を同時に保持し，一度に上記被装着部材８１の所定位置に挿入配置しようとするものである。
【００３３】
図１に示すごとく，本例の部品挿入装置１の先端突出部２は，筒状の外筒部２１と，該外筒部２１の内部において進退可能に配設されたシャフト部２２とを有している。シャフト部２２は長穴２２５を有し，この長穴２２５には外筒部２１から突出させた係合ピン２１５が配置されている。そしてシャフト部２２はこの長穴２２５に対する係合ピン２１５の移動可能距離だけ進退できるように構成されている。また，シャフト部２２の先端には，先端に近づくほど縮径するよう形成されたテーパ頭部２２１が形成されており，これが後述する係合爪部３の拡縮動作に重要な役割を果たす。
【００３４】
本例の係合爪部３は，図１，図５に示すごとく，上記外筒部２１の先端近傍に設けられた支点３０を中心に揺動可能に固定され，外筒部２１の先端を下方に向けて配置した際に自重によって拡径状態となると共に，シャフト部２２が前進した際にはシャフト部２２に当接して縮径状態となるよう構成されている。
【００３５】
より具体的には，上記係合爪部３は，支点３０を中心に回動可能であると共に，その上端に被装着部材８１に当接する当接面３１が設けられ，内方，つまりシャフト部２２に対面する面にシャフト当接面３２が設けられている。また，係合爪部３は，支点３０より上方かつ外方に重心を有しており，自由状態においては，当接面３１を設けた上端部が内方から外方に向けて開くように回動するよう設けられている。そして，シャフト部２２が前進位置にある場合には，図１に示すごとく，シャフト当接面３２がシャフト部２２の外周面に当接して自由回動が規制され，縮径状態が維持される。また，図５に示すごとく，シャフト部２２が後退した際には，シャフト当接面３２に対面する位置に上記テーパ頭部２２１が配置されるので，係合爪部３の自由回動に対する規制が解除され，拡径状態に移行するようになっている。なお，本例では，後述する操作手段６によってシャフト部２２の進退操作を実現している。
【００３６】
また，図１に示すごとく，本例の部品挿入装置１は，２つの部品保持部１１，１２を備えている。
即ち，図３に示すごとく，部品保持部１１は，第１の挿入部品９１であるスナップリングの自由外径よりも小さい内径を有するスナップリング保持部である。このスナップリング保持部１１の内壁面に縮径させたスナップリング９１の外周面を当接させることにより，その拡開力によってスナップリング９１を保持するよう構成されている。なお，本例では，このスナップリング保持部１１を，軸方向に延びる複数の爪状部材により構成した。
【００３７】
また，部品保持部１２は，第３の挿入部品９３としての内周面にＯリング９３１を備えたリング部品を保持するリング部品保持部である。図３に示すごとく，このリング部品保持部１２は，リング部品９３のＯリング９３１の内径よりも大きい外径を有しており，その外壁面に上記Ｏリング９３１を装着させることにより，該Ｏリングの圧縮力によって上記リング部品９３を保持するよう構成されている。そして，この部品保持部１２による第３の挿入部品９３の保持により，その上にスプリング９２５を介して積層された第２の挿入部品９２を合わせて保持することができるようになっている。
【００３８】
また，図１，図３に示すごとく，部品移動手段５は，挿入部品９１〜９３に対面すると共に進退可能に配設された当接部材５１を有しており，該当接部材５１を上記部品保持部１１，１２に保持された上記挿入部品９１〜９３に当接させると共に前進させて上記挿入部品９１〜９３を移動させるよう構成されている。
上記２つの部品保持部１１，１２は，互いに一体化された構造を有している。即ち，略円錐状の部品保持部１２の上方には，固定プレート１１０が配設され，その外周部に上記部品保持部１２が接合されている。
【００３９】
上記固定プレート１１０には，これを貫通する複数の摺動穴１１２が設けられており，各摺動穴１１２に摺動可能にガイドポール５２が挿入配置されている。そして，上記複数のガイドポール５２の上端には上部プレート５３が配設され，下端には上記当接部材５１が配設されている。そのため，上記ガイドポール５２を上記固定プレート１１０に対して摺動させることにより，当接部材５１が上下方向に進退することができるようになっている。
一方，上述した先端突出部２におけるシャフト部２２は，その上端に接合された略Ｌ字状の延長バー５４を上下方向に進退させることにより進退するように構成されている。そして，上記延長バー５４は，上記上部プレート５３の貫通穴５３２を通ってその上方に突出する長さを有している。
【００４０】
また，本例では，上記先端突出部２におけるシャフト部２２と部品移動手段５における当接部材５１とは，互いに共通した操作手段６に接続されている。そして，操作手段６を第１の方向に操作することによって両者の間隔が小さくなり，第２の方向へ操作することによって両者の間隔が大きくなるよう構成されている。
【００４１】
より具体的には，操作手段６は，いわゆるトグルクランプを利用したものであり，ベース部６１と，ベース部６１に対して回動可能に支持された操作アーム部６２と，ベース部６１に対してスライド可能に配設されたポール部６３と，操作アーム部６２とポール部６３の両者に回動支点６４１，６４２をそれぞれ有するリンク部材６４とよりなる。
そして，上記シャフト部２２は，これに接合された上記延長バー５４を介してベース部６１に接合され，一方，上記当接部材５１はガイドポール５２及び上部プレート５３を介してポール部６３に接合されている。
【００４２】
そして，操作手段６の操作アーム部６２を矢印Ａ方向に操作することによって，シャフト部２２と当接部材５１の間隔が小さくなり，反対方向に操作することによって両者の間隔を大きくすることができるようになっている。
さらに，本例では，上記固定プレート１１０に対するガイドポール５２の移動に対して摺動抵抗が生じるように，摺動穴１１２の内面とガイドポール５２との間の摩擦係数を高めてある。そして，この摺動抵抗が，シャフト部２２を後退するように引き上げる力よりも大きく設定してある。そのため，操作アーム部６２を矢印Ａ方向に操作した場合には，まず，シャフト部２２が後退し（引き上げられ），その後，シャフト部２２の長穴２２５と外筒部２１の係合ピン２１５との係合関係によってシャフト部２２の移動と共に外筒部２１が移動し，上記係合爪部３の当接面３１が被装着部材８１に当接する。これにより，外筒部２１及びシャフト部２２の移動が規制され，その後はじめて上記摺動抵抗に抗して当接部材５１が前進する（下降する）。
【００４３】
以上のような構成を有する部品挿入装置１を用いて，上記３つの挿入部品９１〜９３を被装着部材８１の装着穴８１０に挿入配置する手順を簡単に説明する。
まず，図３に示すごとく，部品挿入装置１の部品保持部１１，１２に挿入部品９１〜９３を保持させる。このときの作業方法としては，様々な治具を用いることができ，少なくともスナップリング９１は，その外径を自然状態よりも縮径させるよう規制して部品保持部１１の内部に配置し，再びスナップリング９１の外径の規制を排除する。これにより，スナップリング９１は自己の拡径力によって部品保持部１１の内壁面に保持される。
また，第２，第３の挿入部品９２，９３は，挿入部品９３上にスプリング９２５及び挿入部品９２を重ねた状態で，挿入部品９３の内周面に配設されたＯリング９３２を部品保持部１２の外周面に装着することにより保持される。
【００４４】
次に，図４に示すごとく，挿入部品９１〜９３を保持した部品挿入装置１を，その先端突出部２が被装着部材８１の装着穴８１０を貫通するように配置する。そして，図５に示すごとく，部品挿入装置１の操作手段６の操作アーム部６２を矢印Ａ方向に回動する。この回動の初期段階において，操作手段６のベース部６１及び延長バー５４の上昇と共にシャフト部２２が上昇し，これに伴って係合爪部３が拡径状態となる。また，この拡径状態が実現した時点で，シャフト部２２の長穴２２５の下端に外筒部２１の係合ピン２１５が当接する。
【００４５】
さらに操作アーム部６２を矢印Ａ方向に回動させると，図６に示すごとく，上記長穴２２５と係合ピン２１５との係合関係によってシャフト部２２と外筒部２１とが一体となって上昇し，係合爪部３の当接面３１が被装着部材８１の装着穴８１０の開口端部近傍に当接する。そして，この当接によってシャフト部２２及び外筒部２１の上昇が規制される。
【００４６】
さらに操作アーム部６２を矢印Ａ方向に回動させると，同図に示すごとく，今度は，ガイドポール５２の摺動抵抗に抗して，操作手段６のポール部６３，上部プレート５３及びガイドポール５２が下降（前進）し，これに伴って当接部材５１が下降（前進）する。そして，当接部材５１は，スナップリング（挿入部品）９１に当接してこれを下方に移動させ，さらにこのスナップリング９１がその下方に位置する第２，第３の挿入部品９２，９３を下方に押圧して所望の位置まで移動させる。
【００４７】
これにより，第２，第３の挿入部品９２，９３は，部品保持部１２との係合関係が解かれて被装着部材８１の挿入穴８１１に挿入配置され，かつ，第３の挿入部品９３が有するＯリング９３１，９３２はそれぞれ所望の位置に密着状態で配置される。
また，第１の挿入部品９１であるスナップリングは，部品保持部１１から離れてリング溝８１２の位置まで押し下げられ，このリング溝８１２に面した際に自己の拡径力によって径を大きくし，リング溝８１２内に収容される。
その後，図７に示すごとく，操作手段６の操作アーム部６２を元の位置に復帰させるように回動させ，その後，部品挿入装置１全体を上方に引き抜くことにより，挿入部品９１〜９３の被装着部材８１への装着作業が完了する。
【００４８】
以上のように，本例の部品挿入装置１は，上記のごとく，上記先端突出部２に上記拡縮可能に設けられた係合爪部３を配設してあるので，上記挿入部品を上記被装着部材の装着穴に挿入する際には，上記係合爪部を利用して，容易に挿入圧力を確保することができる。
【００４９】
即ち，上記部品移動手段５を操作して，上記挿入部品を上記係合爪部に相対的に近づくように移動させると，被装着部材８１の装着穴８１０の一方の開口部の周囲の端面には係合爪部３が当接し，また，他方の開口部には上記挿入部品９１〜９３が対面した状態になる。さらに上記挿入部品９１〜９３を相対的に係合爪部３に近づけると，係合爪部３と挿入部品９１〜９３とによって，被装着部材８１の装着穴８１０の部分を挟持するような状態になる。さらに挿入部品９１〜９３を相対的に係合爪部３に近づけると，係合爪部３から被装着部材８１への反力が高まり，挿入部品９１〜９３を近づけようとする応力が直接的に挿入部品９１〜９３の挿入応力となる。
【００５０】
したがって，本例の部品挿入装置１を用いれば，挿入部品９１〜９３を相対的に係合爪部３に近づけようとする応力が，無駄なく直接的に挿入応力に利用される。そして，被装着部材８１を固定する部分からの反力を殆ど作用させる必要がないので，従来の大型の圧入装置のような，挿入圧力を受け止めることができる強固な製品クランプ部を備える必要がない。
【００５１】
また，上記挿入圧力を上記のごとく挟持することによって発生させることができる，かつ上記トグルクランプを利用した操作手段６によって，小さな操作力で大きな挿入圧力を容易に得ることができる。
それ故，本例の部品挿入装置１は，コンパクトで，かつ，必要な挿入圧力を容易に得ることができる構造を有する安価なものとなっている。
【００５２】
実施例２
本例の部品挿入装置１０２は，図８〜図１５に示すごとく，装着穴８２０を有する被装着部材８２の上記装着穴８２０内にリング状の挿入部品９４を挿入配置するための部品挿入装置である。
【００５３】

【００５６】
また，係合爪部３５は，シリンダ部２５１に設けられた支点３５０を中心に揺動可能に固定されていると共に，その後端部３５９を上記シリンダ部２５１内に配置してある。ピストン部２５２は，窪み部２５４を有しこれを係合爪部３５の後端部３５９と係合させており，該ピストン部２５２が前進又は後退することによって係合爪部３５を縮径状態（図１５）又は拡径状態（図１４）に変化させるよう構成されている。また，流体Ｇの導入のため，先端突出部２５の後端プレート２５９には，ガス導入路２５８が形成されている。
【００５７】
また，図８に示すごとく，部品保持部１３は，挿入部品９４を装着可能な外径を有する突出部１３１を先端に有している。また，部品保持部１３は，これと上記先端突出部２５との間隔を拡縮できるよう先端突出部２５に対して相対的に進退可能に設けられている。具体的には，部品保持部１３は，先端突出部２５の後端プレート２５９から延ばされたスライドシャフト１３９に対してスライド可能に配設されている。また，部品保持部１３は，軸方向に沿って設けられた雌ねじ穴１３８を有しており，該雌ねじ穴１３８にはこれに係合する雄ネジ部を有するスクリュー軸５５１を挿設してある。そして，本例の部品移動手段５５は，上記スクリュー軸５５１を回動させることによって部品保持部１３を先端突出部２５に対して進退させるよう構成されている。
【００５８】
また，上記スクリュー軸５５１は，回り止め部５５２に回動可能に支持され，その一端をホルダー部５５３に接続してある。そのため，回り止め部５５２を固定してホルダー部５５３を回転させることにより，部品保持部１３が進退する。また，ホルダー部５５３及びスクリュー軸５５１には，上記先端突出部２５の後端プレート２５９に設けられたガス導入路２５８に連通するガス導入路５５９が形成されている。
【００５９】
さらに，上記ホルダー部５５３は，マシニングセンタに装着可能に構成されている。そして，本例の部品挿入装置１０２は，マシニングセンタにおける１つの工具として利用できるように構成され，マシニングセンタから伝えられる回転動作をホルダー部を介してスクリュー軸５５に伝わるよう構成されている。
【００６０】
以上のような構成を有する部品挿入装置１０２を用いて，上記挿入部品９４を被装着部材８２の装着穴８２０に挿入配置する手順を簡単に説明する。
まず，図８に示すごとく，部品挿入装置１０２の部品保持部１３の突出部１３１に挿入部品９４を装着して保持させる。
【００６１】
次に，同図に示すごとく，挿入部品９４を保持した部品挿入装置１０２を，その先端突出部２５が被装着部材８２の装着穴８２０を貫通するように配置する。このとき，先端突出部２５における係合爪部３５は，装着穴８２０を通過している間には，係合爪部３５をその装着穴８２０の内面に押し当てることにより付勢手段２５３の付勢力に抗して係合爪部３５を縮径状態とする。そして，装着穴８２０を抜け出た瞬間に付勢手段２５３の付勢力によって即時に拡径状態へと復帰させる。
【００６２】
次に，図１０に示すごとく，部品挿入装置１０２を被装着部材８２に対して相対的に後退させる。そして，係合爪部３５の当接面３５０を被装着部材８２に当接させる。
次に，図１１に示すごとく，ホルダー部５５３及びスクリュー軸５５１を回転させて，部品保持部１３を前進させる。
これにより，やがて挿入部品９４は，装着穴８２０に圧入され始める。このとき，実施例１と同様に，被装着部材８２が挿入部品９４と係合爪部３５との間に挟持された状態となっているので，挿入部品９４を前進させる応力は，係合爪部３５からの反力として直接的に挿入圧力として利用することができる。また，本例では，スクリュー軸５５１を回動させる小さなトルクによって大きな挿入圧力が得られ，スムーズに挿入部品９４が装着穴８２０に挿入される。
【００６３】
その後，図１３に示すごとく，ホルダー部５５３及びスクリュー軸５５１を逆方向に回動させることにより，部品保持部１３を後退させる。さらに，部品挿入装置１０２全体を少し前方へ相対的に移動させ，係合爪部３５と被装着部材８２との当接状態を解除する。
【００６４】
そして，図１５に示すごとく，ガス導入路５５９，２５８を介して圧縮空気を先端突出部２５のシリンダ部２５１内に導入する。これにより，ピストン部２５２を前進させ，これに伴って係合爪部３５を回動させ，拡径状態から縮径状態へと状態を変化させる。この状態で，部品挿入装置１０２全体を相対的に大きく後退させることにより，挿入部品９４の被装着部材８２への装着作業が完了する。
【００６５】
以上のように，本例の部品挿入装置１０２においても，上記先端突出部２５に上記拡縮可能に設けられた係合爪部３５を配設してあるので，上記挿入部品を上記被装着部材の装着穴に挿入する際には，上記係合爪部を利用して，容易に挿入圧力を確保することができる。特に，本例の部品挿入装置１０２は，小さな回転トルクを，大きな挿入圧力とすることができ，非常に有効である。
【００６６】
また，本例の部品挿入装置１０２は，マシニングセンタの１工具として適用することができる。そのため，上記被装着部材８２における他の加工工程をマシニングセンタで行った後にこの部品挿入装置１０２による部品挿入工程を連続して行うことが可能である。さらに，連続して，他の加工工程を加えることもできる。それ故，上記被装着部材８２に関する製造工程を大幅に合理化することができる。

【Technical field】
The present invention relates to a component insertion device for inserting and inserting a ring-shaped insertion component into a mounting hole of a member to be mounted.
[0002]
[Prior art]
For example, in a mechanical device such as an A / T (automatic transmission), various ring-shaped components are used. In the process of inserting and arranging these parts in the mounting holes provided in the member to be mounted, since press-fitting is usually performed, a pressing force generating section corresponding to the insertion pressure and a product clamp section for receiving the pressing force generating section are provided. A dedicated press-fitting device is used. For example, in a process requiring an insertion pressure of 5 tons, a dedicated device including an actuator capable of exerting a pressure of 5 tons or more and a product clamp portion capable of receiving a stress of 5 tons or more is used. In addition, as a charging device for a ring-shaped component, for example, a device as described in Patent Document 1 has been proposed.
[0003]
[Patent Document 1]
JP-A-1999-19831
[0004]
[Problem to be solved]
However, the conventional dedicated press-fitting device is very expensive and has a large occupied area. Therefore, it is difficult for the above-mentioned conventional press-fitting device to be rearranged or remodeled in response to a process change or a specification change, and it is also difficult to handle a wide variety of products. Therefore, it has been desired to develop an inexpensive component insertion device which is compact and has a structure capable of easily obtaining a required insertion pressure.
[0005]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide an inexpensive component insertion device having a compact structure capable of easily obtaining a required insertion pressure.
[0006]
[Means for solving the problem]
The present invention relates to a component insertion device for inserting and inserting a ring-shaped insertion component into the mounting hole of a mounted member having a mounting hole,
A component holder for holding the inserted component,
A tip projecting portion projecting so as to penetrate the inside of the insertion component held by the component holding portion and having an outer diameter smaller than an inner diameter of the mounting hole;
It is arranged at the tip end protruding portion, and is expandable and contractable so as to change its state between an expanded state in which the maximum outer diameter is larger than the inner diameter of the mounting hole and a reduced state in which the outer diameter is smaller than the inner diameter. An engagement claw provided on the
And a component moving means for moving the insertion component held by the component holding portion so as to relatively approach the engaging claw portion. .
[0007]
As described above, the component insertion device of the present invention is provided with the engaging claw portion provided on the distal end protruding portion so as to be expandable and contractible. Therefore, when inserting the insertion component into the mounting hole of the mounted member, the insertion pressure can be easily ensured by using the engagement claw portion.
[0008]
That is, when inserting the inserted component into the member to be mounted using the component insertion device, first, the component-holding portion holds the ring-shaped inserted component. Next, the tip protruding portion is passed through the mounting hole of the member to be mounted. At the same time, the diameter of the engaging claw portion in the distal end protruding portion is increased. It should be noted that the method of realizing the enlarged diameter state is different depending on the specific structure of the engaging claw portion and its peripheral portion (see the embodiment).
[0009]
Next, the component moving means is operated to move the inserted component so as to relatively approach the engaging claw. As a result, the engaging claw contacts the end surface around one opening of the mounting hole of the mounted member, and the insertion component faces the other opening. Further, when the insertion component is relatively approached to the engagement claw portion, the engagement claw portion and the insertion component sandwich the mounting hole of the member to be mounted. Further, when the insertion component is relatively moved closer to the engaging claw portion, the stress from the component to the mounted member is increased, and the reaction force from the engaging claw portion to the mounted member is increased, so that the insertion component is approached. The stress directly becomes the insertion stress of the insertion part.
[0010]
That is, if the component insertion device of the present invention is used, the stress that tends to bring the inserted component relatively closer to the engaging claw portion is directly used for the insertion stress without waste. Further, there is almost no need to apply a reaction force from a portion for fixing the mounted member. Therefore, there is no need to provide a strong product clamp portion capable of receiving insertion pressure, unlike a conventional large press-fitting device.
[0011]
Further, since the above-mentioned insertion pressure can be generated by pinching as described above, it is possible to easily employ various link mechanisms and a mechanism for converting a rotational operation into an advance / retreat operation, and a small torque. And a large insertion pressure can be obtained. Therefore, the component insertion device of the present invention is compact and inexpensive.
[0012]
As described above, according to the present invention, it is possible to provide an inexpensive component insertion device having a compact structure capable of easily obtaining a required insertion pressure.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
In the component insertion device of the present invention, the distal end protruding portion has a cylindrical outer cylindrical portion and a shaft portion provided to be able to advance and retreat inside the outer cylindrical portion. The part is fixed so as to be swingable about a fulcrum provided near the tip of the outer cylinder part, and the diameter is increased by its own weight when the tip of the outer cylinder part is arranged downward. It is preferable that, when the shaft portion is advanced, the shaft portion comes into contact with the shaft portion so that the diameter is reduced (claim 2).
In this case, the state change between the diameter-reduced state and the diameter-expanded state of the engagement claw portion can be easily controlled by the advancing and retreating operation of the shaft portion.
[0014]
The component moving means has a contact member facing the insertion component and arranged to be able to advance and retreat, and causes the contact member to contact the insertion component held by the component holding portion. It is preferable to be configured to move the insertion part by moving the insertion part together.
In this case, the insertion component can be moved by moving the contact member with the component holding portion fixed. Therefore, the component holder does not need to be provided movably, and the structure can be simplified.
[0015]
In addition, the shaft portion at the distal end protruding portion and the abutting member of the component moving means are connected to a common operating means, and the operating means is operated in a first direction so that the distance between the two can be increased. In the case where the distance between the two parts is increased by operating in the second direction, and the distance between the two parts is reduced, first, the shaft part retreats by a predetermined distance, and then the contact part is moved. It is preferable that the contact member is configured to move forward (claim 4).
In this case, by operating the common operation means, as one continuous operation, the engagement claw transitions from the reduced diameter state to the enlarged diameter state due to the retraction of the shaft, The operation | movement which shortens the space | interval between a contact member and it can be performed. Therefore, it is very excellent in operability.
[0016]
As a mechanism for controlling the order of the backward movement of the shaft portion and the forward movement of the contact member, for example, when the movement of the contact member is hindered to some extent by frictional resistance or the like, and the two members can move, Can be configured such that only the contact member is moved after the shaft portion is moved preferentially and the movement of the shaft portion is restricted.
The movement of the shaft is restricted, for example, by restricting the relative movement area of the shaft with respect to the outer cylinder at the distal end protruding portion. This can be performed by retreating integrally with the outer cylindrical portion, whereby the engaging claw portion of the outer cylindrical portion comes into contact with the member to be mounted to prevent further movement of the outer cylindrical portion and the shaft portion.
[0017]
The operating means includes a base, an operating arm rotatably supported on the base, a pole slidably mounted on the base, and an operating arm. And a link member having a rotation fulcrum on both of the pole portion and the pole portion. The base portion is joined to one of the shaft portion and the contact member, and the pole portion is joined to the other. Is preferable (claim 5).
[0018]
In this case, by operating the operating arm in one direction, the above-described series of operations, that is, the transition of the engaging claw from the reduced diameter state to the expanded diameter due to the retraction of the shaft and the contact member Advancement can be easily realized. Further, by operating the operation arm in the reverse direction, it is possible to easily realize the transition from the enlarged state to the reduced state of the engaging claw portion due to the retreat of the contact member and the advance of the shaft portion.
Further, the force acting on the operation arm portion can be increased by the so-called leverage principle and applied to the shaft portion and the contact member, and a large insertion pressure can be easily obtained.
[0019]
The insertion component includes a snap ring inserted into a ring groove provided on an inner peripheral surface of the mounting hole of the mounted member, and the component holding portion includes a free outer diameter of the snap ring. A snap ring holding portion having an inner diameter smaller than that of the snap ring, and the outer peripheral surface of the reduced snap ring is brought into contact with the inner wall surface of the snap ring holding portion, whereby the snap ring is expanded by its expanding force. It is preferable to be configured to hold it (claim 6).
[0020]
In this case, the insertion of the snap ring, which is relatively difficult to insert, can be easily performed by using the component insertion device. In particular, by adopting a configuration in which the contact member is moved while the snap ring is held by the snap ring holding portion, the snap ring can be easily and stably held and moved.
[0021]
The insertion component includes a ring component having an O-ring at least on an inner peripheral surface thereof, and the component holding portion has a ring component holding portion having an outer diameter larger than the inner diameter of the O-ring of the ring component. It is preferable that the O-ring is attached to the outer wall surface of the ring component holding portion, so that the ring component is held by the compressive force of the O-ring. .
In this case, by adopting a configuration in which the contact member is moved while the ring component is held by the ring component holding portion, the snap ring can be easily and stably held and moved. .
[0022]
Note that both the snap ring holding portion and the ring component holding portion can be provided as the component holding portion. In this case, the snap ring and the ring component can be inserted at the same time.
[0023]
Next, in the component insertion device of the present invention, the distal end protruding portion has a cylindrical cylinder portion and a piston portion provided to be able to advance and retreat inside the cylinder portion. Is urged in a retreating direction by an urging member disposed in the cylinder portion, and moves forward against the urging force of the urging member by the pressure of the fluid introduced into the cylinder portion. The engagement claw portion is fixed so as to be swingable about a fulcrum provided on the cylinder portion, and a rear end portion is disposed in the cylinder portion. Is configured to engage with the rear end portion of the engagement claw portion and change the engagement claw portion to the reduced diameter state or the increased diameter state by advancing or retracting the piston portion. It is also preferable (claim ).
[0024]
In this case, the diameter of the engagement claw portion can be constantly maintained in the expanded state in the normal state by the urging force of the urging member. Therefore, when penetrating the tip projection into the mounting hole of the member to be mounted, the engaging claw is pressed against the inner surface of the mounting hole so that the engaging claw is reduced in diameter against the urging force. As soon as it comes out of the mounting hole, it can be immediately returned to the expanded state by the urging force. For this reason, it is very easy to penetrate the tip projecting portion into the mounting hole.
An elastic body such as a spring or rubber can be used as the urging member.
[0025]
Further, when the tip protrusion is pulled out from the mounting hole, the piston is moved forward by the pressure by introducing a fluid into the cylinder. As the fluid, various fluids such as air and hydraulic oil can be adopted, but air is most preferable because it is easy to handle.
[0026]
Further, it is preferable that the component holding portion is provided so as to be able to advance and retreat relative to the tip projecting portion so as to expand and contract the distance between the component holding portion and the tip projecting portion.
In this case, the entire component holding portion holding the inserted component moves forward and backward. Therefore, the number of components can be reduced as compared with the case where an abutting member is provided in addition to the component holding portion as described above, and the entire structure can be simplified.
[0027]
The component holding portion is provided so as to be slidable with respect to the tip end protruding portion, and has a female screw hole provided along the axial direction. A screw shaft having a male screw portion to be inserted is provided, and the component moving means is configured to advance and retreat the component holding portion with respect to the tip projecting portion by rotating the screw shaft. Is preferable (claim 10).
In this case, since the rotational force is converted into the insertion pressure of the insertion component, a large insertion pressure can be easily obtained with a small rotation torque.
[0028]
In addition, the component insertion device can be mounted on a machining center configured to be able to attach and detach various tools and to move and rotate the mounted tools to an arbitrary position. It is preferable to have a holder part, and to be configured so that the rotation operation of the holder part is transmitted to the screw shaft.
In this case, the component insertion device can be applied as one tool in the machining center, and the insertion operation of the inserted component can be performed in a series of operations following various processes, thereby further improving the manufacturing process. Can be streamlined.

More specifically, the operating means 6 uses a so-called toggle clamp, and includes a base 61, an operating arm 62 rotatably supported with respect to the base 61, and a base 61. And a link member 64 having pivot points 641 and 642 on both the operation arm 62 and the pole 63.
The shaft portion 22 is joined to the base portion 61 via the extension bar 54 joined thereto, while the contact member 51 is joined to the pole portion 63 via the guide pole 52 and the upper plate 53. Have been.
[0042]
By operating the operation arm 62 of the operation means 6 in the direction of arrow A, the distance between the shaft 22 and the contact member 51 is reduced, and by operating the operation in the opposite direction, the distance between the two can be increased. It has become.
Further, in this example, the friction coefficient between the inner surface of the sliding hole 112 and the guide pole 52 is increased so that sliding resistance is generated with respect to the movement of the guide pole 52 with respect to the fixed plate 110. The sliding resistance is set to be larger than the force for pulling up the shaft portion 22 so as to retreat. Therefore, when the operation arm 62 is operated in the direction of the arrow A, first, the shaft 22 is retracted (pulled up), and thereafter, the elongated hole 225 of the shaft 22 and the engaging pin 215 of the outer cylinder 21 are disengaged. The outer cylinder portion 21 moves together with the movement of the shaft portion 22 due to the engagement relationship, and the contact surface 31 of the engagement claw portion 3 comes into contact with the mounted member 81. Accordingly, the movement of the outer cylinder portion 21 and the shaft portion 22 is restricted, and the contact member 51 advances (downs) against the sliding resistance only after that.
[0043]
The procedure for inserting and arranging the three insertion components 91 to 93 into the mounting holes 810 of the mounted member 81 using the component insertion device 1 having the above configuration will be briefly described.
First, as shown in FIG. 3, the insertion parts 91 to 93 are held by the part holding parts 11 and 12 of the part insertion device 1. As a working method at this time, various jigs can be used. At least the snap ring 91 is arranged inside the component holding portion 11 with the outer diameter regulated so as to reduce the outer diameter from the natural state, and again. The restriction on the outer diameter of the snap ring 91 is eliminated. Thus, the snap ring 91 is held on the inner wall surface of the component holding portion 11 by its own expanding force.
The second and third insertion parts 92 and 93 hold the O-ring 932 disposed on the inner peripheral surface of the insertion part 93 in a state where the spring 925 and the insertion part 92 are overlapped on the insertion part 93. It is held by being mounted on the outer peripheral surface of the part 12.
[0044]
Next, as shown in FIG. 4, the component insertion device 1 holding the insertion components 91 to 93 is arranged such that the distal end protruding portion 2 passes through the mounting hole 810 of the mounted member 81. Then, as shown in FIG. 5, the operation arm 62 of the operation means 6 of the component insertion device 1 is rotated in the direction of arrow A. In the initial stage of this rotation, the shaft 22 rises with the rise of the base 61 and the extension bar 54 of the operating means 6, and the engaging claw 3 is expanded in diameter accordingly. Further, at the time when this diameter-expanded state is realized, the engagement pin 215 of the outer cylinder portion 21 abuts on the lower end of the elongated hole 225 of the shaft portion 22.
[0045]
When the operation arm 62 is further rotated in the direction of arrow A, as shown in FIG. 6, the shaft portion 22 and the outer cylinder portion 21 are integrated with each other due to the engagement relationship between the elongated hole 225 and the engagement pin 215. As a result, the contact surface 31 of the engaging claw 3 comes into contact with the vicinity of the opening end of the mounting hole 810 of the mounted member 81. Then, the rise of the shaft portion 22 and the outer cylinder portion 21 is regulated by this contact.
[0046]
When the operating arm 62 is further rotated in the direction of arrow A, as shown in the figure, the pole 63, the upper plate 53 and the guide pole 53 of the operating means 6 are turned against the sliding resistance of the guide pole 52. 52 descends (advance), and accordingly, the contact member 51 descends (advance). Then, the contact member 51 contacts the snap ring (insertion part) 91 to move it downward, and the snap ring 91 further lowers the second and third insertion parts 92 and 93 located thereunder. To move it to the desired position.
[0047]
As a result, the second and third insertion components 92 and 93 are disengaged from the component holding portion 12 and are inserted and arranged in the insertion holes 811 of the mounted member 81. The O-rings 931 and 932 included in are disposed at desired positions in close contact with each other.
Further, the snap ring, which is the first insertion part 91, is pushed down to the position of the ring groove 812 away from the part holding part 11, and when it faces this ring groove 812, its diameter is increased by its own expanding force, It is housed in the ring groove 812.
Thereafter, as shown in FIG. 7, the operation arm 62 of the operation means 6 is rotated so as to return to the original position, and then the whole of the component insertion device 1 is pulled upward, so that the insertion components 91 to 93 are covered. The mounting work on the mounting member 81 is completed.
[0048]
As described above, in the component insertion device 1 of the present embodiment, as described above, the engaging claw portion 3 provided on the distal end protruding portion 2 so as to be able to expand and contract is provided. At the time of insertion into the mounting hole of the mounting member, the insertion pressure can be easily ensured by utilizing the above-mentioned engaging claw portion.
[0049]
That is, when the component moving means 5 is operated to move the inserted component relatively closer to the engaging claw portion, the end surface around one opening of the mounting hole 810 of the mounted member 81 is formed. Is in a state where the engaging claw portion 3 abuts and the insertion parts 91 to 93 face the other opening. Further, when the insertion parts 91 to 93 are relatively approached to the engagement claw 3, the engagement claw 3 and the insertion parts 91 to 93 sandwich the mounting hole 810 of the mounted member 81. become. Further, when the insertion parts 91 to 93 are relatively approached to the engagement claw part 3, the reaction force from the engagement claw part 3 to the mounted member 81 is increased, and the stress for approaching the insertion parts 91 to 93 is directly increased. And the insertion stress of the insertion parts 91 to 93.
[0050]
Therefore, if the component insertion device 1 of the present embodiment is used, the stress that tends to relatively bring the insertion components 91 to 93 closer to the engaging claw portions 3 is directly used for the insertion stress without waste. Further, since there is almost no need to apply a reaction force from a portion for fixing the mounted member 81, there is no need to provide a strong product clamp portion capable of receiving insertion pressure, unlike a conventional large press-fitting device. .
[0051]
Further, the insertion pressure can be generated by sandwiching as described above, and a large insertion pressure can be easily obtained with a small operation force by the operation means 6 using the toggle clamp.
Therefore, the component insertion device 1 of this embodiment is compact and inexpensive having a structure that can easily obtain a necessary insertion pressure.

It is configured to advance by the pressure against the urging force of the urging member 253.
[0056]
The engaging claw portion 35 is fixed so as to be able to swing around a fulcrum 350 provided on the cylinder portion 251, and a rear end portion 359 is disposed in the cylinder portion 251. The piston portion 252 has a concave portion 254 which is engaged with the rear end portion 359 of the engagement claw portion 35, and the engagement claw portion 35 is reduced in diameter by the piston portion 252 moving forward or backward. (FIG. 15) or the diameter is changed to the expanded state (FIG. 14). Further, for introducing the fluid G, a gas introduction passage 258 is formed in the rear end plate 259 of the front end protruding portion 25.
[0057]
As shown in FIG. 8, the component holding portion 13 has a protruding portion 131 having an outer diameter at which the insertion component 94 can be mounted, at the tip. The component holder 13 is provided so as to be relatively movable with respect to the distal end protruding portion 25 so that the distance between the component holding portion 13 and the distal end protruding portion 25 can be enlarged or reduced. Specifically, the component holding portion 13 is slidably provided on a slide shaft 139 extending from a rear end plate 259 of the front end protruding portion 25. The component holding part 13 has a female screw hole 138 provided along the axial direction, and a screw shaft 551 having a male screw part engaged with the female screw hole 138 is inserted into the female screw hole 138. . The component moving means 55 of the present embodiment is configured so that the component shaft 13 moves forward and backward with respect to the distal end protruding portion 25 by rotating the screw shaft 551.
[0058]
Further, the screw shaft 551 is rotatably supported by the rotation preventing portion 552, and one end thereof is connected to the holder portion 553. Therefore, by rotating the holder portion 553 while fixing the rotation preventing portion 552, the component holding portion 13 moves forward and backward. Further, a gas introduction path 559 communicating with a gas introduction path 258 provided on a rear end plate 259 provided on the front end protruding portion 25 is formed in the holder portion 553 and the screw shaft 551.
[0059]
Further, the holder 553 is configured to be mountable on a machining center. The component insertion device 102 of this embodiment is configured to be used as one tool in a machining center, and is configured to transmit a rotating operation transmitted from the machining center to the screw shaft 55 via a holder.
[0060]
A procedure for inserting and inserting the insertion component 94 into the mounting hole 820 of the mounted member 82 using the component insertion device 102 having the above configuration will be briefly described.
First, as shown in FIG. 8, the insertion component 94 is mounted and held on the projecting portion 131 of the component holding unit 13 of the component insertion device 102.
[0061]
Next, as shown in the figure, the component insertion device 102 holding the insertion component 94 is arranged so that the distal end protruding portion 25 passes through the mounting hole 820 of the mounted member 82. At this time, while the engaging claw 35 of the distal end protruding portion 25 is passing through the mounting hole 820, the engaging claw 35 is pressed against the inner surface of the mounting hole 820 to apply the urging means 253. The engaging claw 35 is reduced in diameter against the force. Then, at the moment when it comes out of the mounting hole 820, the urging force of the urging means 253 immediately returns to the expanded state.
[0062]
Next, as shown in FIG. 10, the component insertion device 102 is retracted relatively to the mounted member 82. Then, the contact surface 350 of the engaging claw 35 is brought into contact with the mounted member 82.
Next, as shown in FIG. 11, the component holder 13 is advanced by rotating the holder 553 and the screw shaft 551.
As a result, the insertion part 94 starts to be pressed into the mounting hole 820. At this time, similarly to the first embodiment, since the mounted member 82 is sandwiched between the insertion part 94 and the engagement claw 35, the stress for moving the insertion part 94 forward is limited to the engagement claw. It can be directly used as an insertion pressure as a reaction force from the portion 35. Further, in this example, a large insertion pressure is obtained by a small torque for rotating the screw shaft 551, and the insertion part 94 is smoothly inserted into the mounting hole 820.
[0063]
Thereafter, as shown in FIG. 13, the holder 553 and the screw shaft 551 are rotated in the opposite directions, so that the component holder 13 is retracted. Further, the whole of the component insertion device 102 is relatively moved slightly forward, and the contact state between the engagement claw portion 35 and the mounted member 82 is released.
[0064]
Then, as shown in FIG. 15, compressed air is introduced into the cylinder portion 251 of the distal end protruding portion 25 via the gas introduction passages 559 and 258. Thereby, the piston portion 252 is advanced, and the engagement claw portion 35 is rotated accordingly, thereby changing the state from the expanded state to the reduced state. In this state, the operation of mounting the insertion component 94 on the mounting target member 82 is completed by relatively retreating the entire component insertion device 102.
[0065]
As described above, also in the component insertion device 102 of the present embodiment, since the engaging claw 35 provided so as to be expandable and contractible on the distal end protruding portion 25 is provided, the inserted component is attached to the mounted member. At the time of insertion into the mounting hole, it is possible to easily secure the insertion pressure by using the engaging claw portion. In particular, the component insertion device 102 of the present embodiment is very effective because a small rotation torque can be used as a large insertion pressure.
[0066]
Further, the component insertion device 102 of this example can be applied as one tool of a machining center. Therefore, it is possible to continuously perform the component insertion process by the component insertion device 102 after performing another processing process on the mounted member 82 in the machining center. Further, other processing steps can be added continuously. Therefore, the manufacturing process for the mounted member 82 can be greatly rationalized.
