为加工套类工件,我们设计了手动液压心轴。效果较好,带莫氏锥柄的心轴体1(附图)上均布三个键槽与径向孔相通,三个弹性夹爪长键2,用螺钉4固定在槽内,当加压柱塞5推进时,柱塞3在液体作用下径向移动,使三个夹爪长键2径向撑紧,从而使工件定心和夹紧。加压柱塞5的端面上有中心孔,便于 We have designed a manual hydraulic mandrel for the machining of sleeve type workpieces. The effect is better, with a Morse taper shank mandrel body 1 (Figure) uniform distribution of the three keyway and radial hole, three elastic jaws long key 2, with screws 4 fixed in the tank, when the pressure When the plunger 5 is advanced, the plunger 3 moves radially under the action of the liquid to radially hold the three jaw long keys 2, thereby centering and clamping the workpiece. Pressure plunger 5 has a center hole on the end face, easy
