摘要： A wrench (10) includes a wrench body (11) having a ring portion (111) and a handle portion (112). A retainer (13) that holds a plurality of wedge members (12) at predetermined intervals in a circumferential direction of the ring portion (111) is disposed inside the ring portion (111). Wedge guide grooves (14) are formed on the inner circumferential surface of the ring portion (111) to be arranged at intervals corresponding to those of the wedge members (12). Each of the wedge guide grooves (14) has a free region (141) which maintains the corresponding wedge member (12) in a free state in which the wedge member (12) moves freely between a bottom surface of the corresponding wedge guide groove (14) and the outer circumferential surface of a fastening member (2), and left-hand and right-hand wedge regions (142, 143) each of which maintains the corresponding wedge member (12) in a caught state in which the wedge member (12) is caught between the bottom surface of the corresponding wedge guide groove (14) and the outer circumferential surface of the fastening member (2). The wrench (10) is provided with a changeover mechanism (15) for operating the retainer (13). By use of the changeover mechanism (15), the retainer (13) is moved to a position at which the wedge member (12) faces the corresponding free region (141), a position at which the wedge member (12) faces the corresponding left-hand wedge region (142), or a position at which the wedge member (12) faces the corresponding right-hand wedge region (143).

摘要： An end mill chucking structure for chucking an end mill having a relatively small diameter and used, for example, for deep milling of a die. The end mill chucking structure includes an end mill holder (10) and an end mill (12). A holder body has a taper hole (13h) formed therein. The end mill includes an end mill body (15) and a cutting tip (16) provided at an end portion of the end mill body. A portion of the end mill body located opposite the cutting tip serves as a tapered shank portion (15a). The shank portion (15a) and the rest of the end mill body are bounded by a shoulder (15c) extending outward from the surface of the shank portion. The shank portion (15a) is press-fitted or shrink-fitted into the taper hole (13h) such that the end face (13i) of the holder body abuts the shoulder (15c) of the end mill body, through application to the holder body of heat at a temperature lower than a conventional shrink-fitting temperature.

摘要： A tool holder includes a holder body (2) which in turn includes a shank portion (3), a flange portion (4), and a tool attachment portion (6); a tapered cone (8) fitted to the shank portion; an elastic member (7) interposed between a rear-end face of the flange portion (4) and a front-end face of the tapered cone (8); and a stopper member (9) disposed on the shank portion so as to support a rear-end face of the tapered cone (8). The outer surface of the tapered cone (8) is tapered at an angle equal to that at which the wall surface of a tapered hole (21) formed in a spindle of a machine tool is tapered. The inner surface of the tapered cone (8) and the outer surface of the shank portion (3) are equally tapered at an angle smaller than the angle at which the outer surface of the tapered cone (8) is tapered. Through drawings of the holder body, the tapered cone (8) expands radially to thereby be tightly held within the tapered hole (21). A spacer is bonded to the end face of the spindle so as to eliminate a gap which is formed between the flange portion and a spindle.

摘要： In a tool holder, a tip run-out correction mechanism includes an annular stepped portion (41) formed on a cylindrical support portion (48) of a holder body (31); a ring member (42) rotatably fitted onto the annular stepped portion (41); an eccentric cam (43) disposed within the ring member (42), the eccentric cam (43) extending radially through the ring member (42) and being rotatable about a radially extending axis; and a pin (44) disposed within the ring member (42) to be movable along a direction parallel to the centre axis of a flange portion (33) of the holder body (31). One end of the pin (44) is in contact with the eccentric cam (43), and the other end of the pin (44) is in contact with a rear end face of a clamp sleeve (38) which clamps a tool (29) inserted into a chuck sleeve (34) of the holder body (31). The eccentric cam (43) is rotated so as to adjust a pressing force that the pin (44) applies to the rear end face of the clamp sleeve (38), thereby to elastically deform a base end portion (341) of the chuck sleeve (34) in a radial direction in such a manner that tip run-out of the tool approaches zero.
