本実施形態では、ロータシャフトBの軸部B1が支持部22に載置され保持されることで、ロータシャフトBが圧入姿勢を維持したまま圧入位置で支持される。具体的には、ロータシャフトBの仮圧入位置にインペラAが圧入された状態で支持部22に支持される。
押圧部33は、インペラAの上面A2に当接する押圧面33aを含む。押圧部33は、圧入ツール32が圧入方向となる押圧方向に移動されることで、押圧面33aがインペラA(圧入部品A)に当接する。押圧面33aがインペラAに当接した状態で押付方向に移動されることで、インペラAが押圧完了位置へ移動される。本実施形態においては、押圧面33aは、インペラAの上面A2と当接し、インペラAが押圧方向に押し付け移動されることでインペラAが押圧完了位置へ移動される。

次に、本実施形態に係る圧入装置10を用いた圧入方法、およびこれを用いた圧入製品Cの製造方法について、図10A~図10Dを用いて説明する。図10A~図10Dは、各工程におけるインペラA(圧入部品A)、ロータシャフトB(被圧入部品B)および圧入ツール32の位置関係を模式的に示している。図10A~図10Dにおいて圧入部品AのインペラAは矩形状(直方体状)の部品として描いている。また図10A~図10Dにおいて治具支持ユニット100は省略している。
圧入部品Aおよび被圧入部品Bを準備する準備工程と、
圧入部品Aまたは被圧入部品Bのいずれか一方を圧入ツール32によって圧入方向へ移動させていずれか他方へ圧入させる圧入工程と、含む。
本実施形態では、まず制御部7が第一寸法H1および第二寸法H2に基づき、複数の規制部34の中から適した一つの規制部34を選択する。次に制御部7は、圧入ツール32が支持部22に配置される圧入部品Aから上方へ離間した圧入待機位置で、選択した規制部34が押圧部33に対向する対向位置に位置するように圧入治具50を回転させることで、圧入間隔寸法HTを調節する。制御部7は、選択した規制部34が押圧部33に対向する対向位置に位置した状態で、圧入治具50を圧入移動体90に対して相対的に上方に移動させる。これにより、圧入治具50の配列部52が回転止め部94に接触する。詳しくは後に説明する。
このように、本実施形態の圧入方法は、圧入ツール32の圧力値が予め設定された所定の値に達したことを検出する圧力検出工程を含む。
圧入停止位置調節工程は、予め設定される管理すべき基準間隔寸法Haと、圧入間隔寸法HTによって圧入された圧入製品Cの基準間隔寸法Haに対応する箇所の実際寸法との差の絶対値が、予め定められた許容誤差値未満となるように、圧入間隔寸法HTを設定する圧入間隔設定工程を含む。
圧入間隔寸法HTとは、押圧面33aと規制面34aとの間隔であり、押圧面33aの圧入停止位置と規制面34aの圧入停止位置との間隔を言う。図9に示したように、本実施形態において、圧入間隔寸法HTは、回転止め部94から押圧面33aまでの寸法HRと、回転止め部94に圧入治具50の平面521が当接した状態のときの圧入治具50の一方の平面521から押圧部33に対向する他方の平面521に設けられる規制部34の規制面34aまでの寸法HSとの差となる。
つまり圧入停止位置は可動部31の上下移動によって変化するものではない。また、圧入間隔寸法HTも可動部31の上下移動によって変化するものではない。本実施形態では、圧入停止位置および圧入間隔寸法HTは、圧入治具50に構成される高さの異なる複数の規制部34の中から一つが規制面34aとして選択されることで変更されるものである。
ロータシャフトBの段差面B3aから軸部B1の上面B4までの軸部B1の長さを第一寸法H1と呼ぶ。第一測定部2は、この第一寸法H1の測定を含む。
インペラAの回転軸線Ax方向の長さを第二寸法H2と呼ぶ。第二測定部3は、この第二寸法H2の測定を含む。
この場合、二つ目の圧入製品CBの製造時には、第三寸法H3を一つ目の圧入製品CAの製造時の第三寸法H3よりも小さくなるように調整することにより、二つ目の圧入製品CBの製造時の基準間隔寸法Haが一つ目の圧入製品Cの製造時の基準間隔寸法Haと等しくなるようにする。
本実施形態においては、この圧入間隔寸法HTは、突出高さH4の異なる複数の規制部34のうちから適した一つの規制部34を選択することにより、第三寸法H3に近い値とすることができる。
図13は、圧入装置10が有する複数の規制部34の情報を示している。なお、ここでは押圧部33に対向する平面521の圧入停止位置と、押圧面33aの圧入停止位置との差が10.000mmであるものとする。また、規制面34aが押圧面33aよりも下方に位置する場合はプラスの符号を付し、規制面34aが押圧面33aよりも上方に位置する場合はマイナスの符号を付すものとする。
第二規制部342の突出高さH4は10.020mmであり、圧入間隔寸法HTは0.020mmである。
第三規制部343の突出高さH4は10.000mmであり、圧入間隔寸法HTは0.000mmである。
第四規制部344の突出高さH4は9.980mmであり、圧入間隔寸法HTは-0.020mmである。
第五規制部345の突出高さH4は9.960mmであり、圧入間隔寸法HTは-0.040mmである。
なお、上述した説明における各部の寸法は、説明のために用いたのであって、上述した数値に限定されるわけではない。
具体的には、例えば上記の例では、制御部7が第二規制部342を選択した後、制御部7は、選択された第二規制部342が押圧部33の対向位置に位置するように圧入治具50を回転させる。この状態で可動部31を下降させると、まず押圧部33がインペラAの上面A2に接触する。さらに可動部31を下降させると、押圧部33によってインペラAがロータシャフトBに圧入されていく。押圧部33がインペラAの上面A2に接触してから可動部31を下降させると、規制部34がロータシャフトBの軸部B1の上面B4に接触する。制御部7は、規制部34がロータシャフトBの軸部B1の上面B4に接触したと判定したら、可動部31の下降を停止させる。あらかじめ圧入間隔寸法HTが第三寸法H3に最も近くなるように第二規制部342が選択され、この第二規制部342にて圧入動作が規制されるので、基準間隔寸法Haの寸法精度を許容誤差値の範囲内に収めることができる。
この検査工程によって、製造された圧入製品Cの基準間隔寸法Haに該当する箇所の寸法(完了間隔寸法)が所望の値となっているかを検査することにより、圧入製品Cが良品か不良品かを判別することができる。上述した例で言えば、完了間隔寸法が10.000mmプラスマイナス0.010mm以内の範囲であれば良品と判断され、それ以外であれば不良品と判断される。
圧入部品Aまたは被圧入部品Bのいずれか一方を圧入ツール32によって圧入方向へ移動させていずれか他方へ圧入させる圧入方法であって、
圧入ツール32は、
圧入部品Aと当接する押圧面33aを備える押圧部33と、
被圧入部品Bと当接する規制面34aを備える規制部34と、を有し、
押圧部33の押圧面33aの圧入方向位置と規制部34の規制面34aの圧入方向位置は、圧入部品Aまたは被圧入部品Bのいずれか一方が所定の圧入停止位置で停止するように設定され、
圧入方法は、
圧入部品Aおよび被圧入部品Bのそれぞれの部品寸法に応じて設定される圧入停止位置となるように押圧部33の押圧面33aと規制部34の規制面34aとの間の圧入方向の圧入間隔寸法HTを調節する圧入停止位置調節工程と、
圧入部品Aを被圧入部品Bへ圧入させる圧入工程と、
規制部34が被圧入部品Bに当接することで、圧入部品Aの被圧入部品Bに対する圧入を停止させる圧入完了工程と、を有する。
複数の押圧部333は、圧入治具350の本体部351の回転軸線Bx回りの円として本体部351に設定される同一円の円周と回転軸線Bxから放射方向に延びる線とが直交する交点の位置に、それぞれ設けられている。押圧部333は、該回転軸線Bx回りの円の円周上において所定の間隔で設けられている。このような圧入治具350も回転軸線Bx回りに回転することにより、任意の一つの押圧部333を圧入部品Aに当接可能な位置に位置させることができる。
複数の押圧部333は、その下面333dから境界面333cまでの長さが互いに異なっている。したがって、円板状の本体部351を回転させることにより、設定したい圧入間隔寸法HTを有する押圧部333を、圧入部品Aに当接可能な位置に位置させることができる。
