次に、上記クランパーCの作動について説明する。Next, the operation of the clamper C will be explained.
加工機械の金型りを交換する場合には、第4図に示すよ
うに、油室6bに圧油を供給して、作動軸5を退行姿勢
にして、金型りを交換する。When replacing the mold of the processing machine, as shown in FIG. 4, pressurized oil is supplied to the oil chamber 6b, the operating shaft 5 is placed in the retracted position, and the mold is replaced.
その後、金型りをクランプする時には、第2図に示すよ
うに、油室6bの圧油を逃すと駆動バネ80弾発力によ
って作動軸5が進出するのと併行して、クランプ爪3が
金型り上方筐で進出し、係止部3aがストッパー15に
係止される。After that, when clamping the mold, as shown in FIG. 2, when the pressure oil in the oil chamber 6b is released, the actuating shaft 5 moves forward due to the elastic force of the drive spring 80, and the clamp claw 3 moves forward. The upper housing of the mold advances, and the locking portion 3a is locked with the stopper 15.
更に作動軸5が進出すると、クランプ爪3と傾斜抑圧面

って、クランパーが邪魔にならないようにし、工具等を
簡単に交換することが出来る。In other words, the clamper's operating shaft is slid back and forth within the sliding guide hole via a drive device, and the tip of the operating shaft is moved in and out of the sliding guide hole, making it easy to replace tools, etc. of the processing machine. When doing so, the tip of the operating shaft is retracted from the tip of the guide hole, and the clamper is moved out of the side edge of the tool, etc., so that the clamper does not get in the way and the tool, etc. can be easily replaced. .
昔た、作動軸の傾斜抑圧面に前後摺動自在に接触するク
ランプ爪を設け、このクランプ爪を介して作動軸でクラ
ンプする構造なので、工具等の取付部の形状を特殊な形
状に加工する必要もない。In the past, a clamp claw was provided that slidably contacted the tilt suppression surface of the operating shaft, and the structure was such that the operating shaft was clamped via this clamp claw, so the shape of the attachment part for tools, etc. had to be machined into a special shape. There's no need.
また、クランパく−は簡単な構造であり、しかも摺動案
内孔もピストン室も取付基準面に平行に形成され、クラ
ンパ一本体に対して傾斜していないので、その切削加工
等も容易となることから、簡単に安価に製作することが
