ことを特徴とする工作機械用割出しチヤツク。 It has two replaceable clamp claws, one of which is rotatably supported on a clamp piston that is slidably fitted in the radial direction of the chuck body.
The other clamp claw is fixed to a square piece of an indexing mechanism that is rotatably supported on the chuck body, and a pair of plungers are alternately brought into contact with the indexing surface of the square piece, thereby indexing the square piece in stages. In an indexing chuck performed in a conventional manner, a locator pin having a sloped surface formed on the outer periphery of the shaft is supported within the chuck body so as to be slidable only in the axial direction of the chuck body, and the sloped surface that engages with the sloped surface of the locator pin is A lock piston formed at the end of the shaft is fitted into the cylinder chamber of the chuck body so as to be slidable in the radial direction of the chuck body, and a rotating shaft rotatably supported by a rotary valve arranged at the rear of the spindle is attached to the rear of the spindle. A piston rod is fitted in a cylinder chamber within the rotating shaft so as to be able to slide in the axial direction, a positioning rod which is axially connected to one end of the piston rod is screwed onto the locator pin, and the end face of the locator pin is screwed onto the locator pin. An indexing chuck for machine tools characterized by supporting one end of a workpiece.
