摘要： PROBLEM TO BE SOLVED: To shorten the time required for changing a tapered hollow shaft insert, a tool, a workpiece, by enabling a supporting body to be pressed against the edge of the axial hole of a hollow shaft facing to a working spindle, exceeding the edge of a receiving part due to spring action. SOLUTION: A ball 9 is brought in contact with an edge 12 faced to a working spindle 4, of the hole 6 in the radial direction of a tapered hollow shaft insert 1. The edge 12 is formed with a slope 13 for running on, and the slope 13 for running on replaces movement of the ball 9 in the radial direction with movement of the tapered hollow shaft insert 1 in the axial direction of the working spindle 4. As a result, the balls 9 acting as a supporting body 8 are fitted to the tapered hollow shaft insert 1, and before final fastening of the tapered hollow shaft insert 1, it is temporarily held with fastening jaws 5.

摘要： PROBLEM TO BE SOLVED: To easily mount and demount a tool body to a tool, holder, and reduce the run-out of the tool body to the tool holder, by supplying the high oil pressure to a hydraulic supply passage formed on a fitting part, from an external. SOLUTION: A mounting part 14 comprises a step part 15 on a boundary part of a small diameter part 14a and a large diameter part 14b. An abrasive wheel 21 of small diameter, and a recessed fitting part 22 to be thermally inserted to the mounting part 14 of a tool holder 10 are integrally molded in a tool body 20. The fitting part 22 comprises the first fitting hole 22a and the second fitting hole 22b, and a step part 23 is formed on a boundary part thereof. When the fitting part 22 is fitted to the mounting part 14, a prescribed space is formed between the step part 23 and the step part 15. When the high oil pressure is supplied to the space A, an oil film of high pressure is formed on a fitting face of the mounting part 14 and the fitting part 22, and acts as a lubricant, whereby the slippage and the inclination in an axial direction, of the fitting part 22, are corrected. Accordingly, the tool unit 1 free from the run-off can be obtained. Further, the tool body 20 can be easily removed from the tool holder 10 by the oil pressure.

摘要： PROBLEM TO BE SOLVED: To highly accurately attach a tool holder to a tool rest with ease by a two face constraint and one shaft clamping method and miniaturize the tool rest. SOLUTION: The parallelism of a tool holder 10 is maintained in the X and Z directions by jointing the constraint faces 11 and 12 of the tool holder 10 to the two flat faces 21 and 22 of a turret 20, which are adjacent to each other. A clamp shaft 14 is projected in the direction of the bisector of the angle between the constraint faces 11 and 12 to be inserted into the insertion hole 24 of the turret 20, determining the center height of the tool holder 10 in the Y direction. A clamp piece 26 is tightened by a clamp bolt 27, clamping the clamp shaft 14 so as to be pulled, and the constraint faces 11 and 12 are pressed against the flat faces 21 and 22, determining the datum position of the tool holder 10 in the turning direction.

摘要： PROBLEM TO BE SOLVED: To improve the reproducibility of a mounting position of a machining tool while simply carrying out the fine adjustment of the mounting position in a working tool holder for mounting the machining tool to a machining tool or the like to be adjustably turned horizontally and vertically. SOLUTION: A machining tool holder 1 supporting the machining tool to be adjustably turned horizontally and vertically has a manual swivel stage mechanism 4 supporting the working tool 7 capable of being turned, a manual θstage mechanism 3 supporting the swivel stage mechanism 4 capable of being horizontally turned and a base stand 2 supporting the θ stage mechanism 3. The base stand 2 is fixedly mounted to a machine tool like a lathe. Since the mounting angular position of the machining tool 7 (horizontal turning angular position, upward and downward inclination angular position) is adjusted by utilizing these manual precision stages, the reproductiveness of the mounting position is improved and the fine adjustment of the mounting position can be simply carried out.

摘要： A coupling system (1) is provided for lockably coupling together machine tool components that comprises a male coupling (3) having a recess (19) at a distal end that includes follower surfaces (24), and female coupling (9) having an opening (31) disposed along its longitudinal axis for receiving the distal end of the male coupling (3), and a pair of opposing jaw members (12) pivotally mounted in the opening (31) and having cam surfaces (44) engagable with the follower surfaces (24) of the male coupling (3). The system (1) includes a drive train (13) for pivotally moving the jaw members (12) apart in order to interengage the cam (44) and follower surfaces (24) of the female (5) and male (3) couplings that includes an axially movable, ball-shaped element (52) disposed in opposing recesses (50) present in the jaw members (12) for prying the jaw members (12) apart, a pair of opposing wedge members ( 58) for moving the ball-shaped drive element (52) axially toward the free ends of the jaw members (12), and a screw (64) having right and left hand threads on either of its ends for moving the wedge members (58) toward and away from one another. The drive train (13) generates high clamping forces between the male (3) and female (5) couplings in a small envelope and with a large degree of mechanical advantage.
