図2~図5に示すように、本体部材12は、クランク軸6に対して同心状になるように筒部11aに微小間隔を空けて相対回転自在に外嵌された環状の部材である。本体部材12の左端部に形成された固定用フランジ12dを複数のボルト12eによって本体フレーム3に固定することにより、本体部材12をプレス機械1の本体フレーム3の右側外側面に固定している。
この第1対向壁部12cには、クランク軸6の軸心Xから導入孔11pまでの距離と同距離離隔した位置において軸心Xと平行な4つの第1支持孔12pが円周4等分位置に形成されている。第1支持孔12pはピン部材14が左右方向へ摺動自在に挿入される断面円形の孔に形成されている。
環状シリンダ孔17内には、この環状シリンダ孔17よりも短い環状ピストン部材13が軸心Xと平行方向へ摺動自在に装着されている。環状ピストン部材13の左端側部分には大径部13cが形成され、環状シリンダ孔17には大径部13cよりも長い大径孔部17cが形成されている。
環状ピストン部材13は、ピン部材14よりも軽量な金属(例えばアルミニウム合金)で構成され、環状シリンダ孔17内に左右方向(軸心Xと平行方向)へ移動可能に装着されている。図3,図4に示すように、この環状ピストン部材13は、クランク軸6の軸心Xと直交状の左端面13a及び右端面13bを備え、環状シリンダ孔17の長さよりも短く形成されている。
各ピン部材14には、その左端部分に保持孔13pの径よりも大径に形成され且つ第1作動室17a内に臨む係止部14a(鍔状部分)が形成されている。
ロック機構30は、プレス機械1の稼働中に、環状ピストン部材13を最大限後退させた後退位置にロックし、4つのピン部材14を退避位置にロックするものである。環状ピストン部材13の左端近傍部分の下側外周部分にはロック用凹部13rが形成されている。ロック機構30は、環状ピストン部材13が後退位置にあるとき、ロック用凹部13rに係合可能なピストン部材31を有する複動型の小型エアシリンダ30aを有する。
このスライドロック装置10によれば、本体部材12に環状シリンダ孔17を形成し、この環状シリンダ孔17に環状ピストン部材13を軸心Xと平行方向へ移動可能に装着し、第1作動室17aの加圧エアで環状ピストン部材13を前進位置に駆動し、第2作動室17bの加圧エアで環状ピストン部材13を後退位置に切換えることができる。
1)保持孔13pと第1,第2支持孔12p,15pとピン部材14の数は4つに限定されるものではなく、3つ以下でもよく5つ以上でもよい。導入孔11pの数は6つに限定されるものではなく、5つ以下でもよく7つ以上でもよい。導入孔11pの数に応じて導入孔11pの周方向のサイズも適宜設定可能である。
3)前記実施例では、ピン部材14の係止部14aが環状ピストン部材13の左端面から左方に突出した例を説明したが、環状ピストン部材13の左端面に凹部を形成して係止部14aの左端面と環状ピストン部材13の左端面とが同一面になるように形成しても良い。
