Abstract

PURPOSE:To improve cutting capability and extend cutting tool life in such a way that the grasping force of collet chucks of a peeling machine to cut a cylinder-shaped material in the assigned diameter of its outer periphery or in tapered shape thereof, is freely adjusted by oil pressure. CONSTITUTION:A third collet chuck 55 is added to a second collet chuck 49 in a spindle head 10, a material is held at two points by which vibratory shaking of the material is entirely eliminated, therefore, cutting rate is enlarged and cutting capability can be improved remarkably. Grasping force is freely adjustable, and life of the cutting tool can be extended, because hydraulic pressurization is applied to the grasping force of the first collet chuck 22, the second collet chuck 49 of the spindle head 10 and the third collet chuck 55.

An inner sleeve, which accommodates a piston punched on its outer circumferential surface in a cylinder chamber and is pressurized by hydraulic pressure, is inserted into the outer sleeve, and a first collet chuck attached to the inner sleeve is inserted at the tip end. The spherical part provided on the outer periphery of the collet piece of the split assembly configured by forming slot grooves in the axial direction is connected to the taper part formed on the inner periphery of the end of the first collet housing provided around the end of the outer sleeve. A collet guide arranged so as to be in constant contact with the part, and an outer sleeve fitted with a cylinder provided with two cylinder chambers in a rotary main shaft cylinder which is rotatably supported on the frame via a bearing, are inserted into the outer sleeve. An intermediate sleeve, in which a piston protruding from the outer circumferential surface is housed in one cylinder chamber of the cylinder and is pressurized by hydraulic pressure, is inserted into the outer sleeve, and the outer circumferential surface is inserted into the other cylinder chamber of the cylinder. An inner sleeve that housed the piston projecting above and was pressurized by hydraulic pressure was inserted into the intermediate sleeve, and was locked to the third collet housing that was pressurized by the intermediate sleeve. A collet with a split structure in which the second collet chuck has a slotted groove formed in the axial direction at its tip. The spherical part provided on the outer periphery of the piece is arranged so as to be in constant contact with the tapered part formed on the inner periphery of the end of the second collet housing fixed to the end of the outer sleeve, and is pressurized by the inner sleeve. A third collet chuck with a split structure in which slotted grooves are formed in the axial direction at the distal end of the third collet chuck has a spherical surface provided on the outer periphery of the collet piece that locks the second collet chatter. 3. A movable body is disposed so as to be in constant contact with the tapered part formed inside the end of the collet chuck, and is rotatably and squidally movable at one end of the rotating main shaft cylinder, and a bearing is mounted on the outer periphery of the movable body. A slide effecting body is integrally interposed and has a male screw portion formed on its outer circumferential surface, and a gear portion is formed on the outer circumferential surface of the slide effecting body to constantly mesh with a worm gear formed as a part of the frame. and a rotary body having a female screw portion formed on the inner circumferential surface thereof that is always screwed together with the male screw portion, and a cutter head rotatably installed integrally on the end surface of the rotary main shaft cylinder. A cutting tool holder equipped with a cutting tool pointing toward the center of the material is attached to the cutter head so that it can be moved in and out, and the outer peripheral surface of the cutting tool holder is an inclined surface that tightly fits with the inner peripheral tapered surface of a taber ring fixed to the end surface of the movable body. The main spindle head is formed in such a way that the opposing diameter of the cutting tool can be appropriately adjusted by controlling the rotation of the worm gear, which prevents chatter of the material and increases cutting capacity by increasing the cutting amount. In addition to significantly improving the gripping force of the collet chuck, the gripping force of the collet chuck can be freely adjusted, providing an appropriate gripping force and extending the life of the cutting tool.This is an excellent cutting device for this type of peeling machine. It's something you get.
