Abstract: A cut-away cutting tool has two slit forming blade portions and a peeling blade portion interposed between the two slit forming blade portions. The two slit forming blade portions respectively form slits on an insulating coating of a flat conductor wire. On the other hand, the peeling blade portion peels off a portion of the insulating coating between the slits formed by the two slit forming blade portions.

Abstract: A machining apparatus includes a movement direction converting mechanism that converts lowering movement of a first punch into raising movement of a second punch and converts lowering movement of the second punch into raising movement of the first punch. The first punch and the second punch are raised and lowered in an alternating manner by this movement direction converting mechanism. Accordingly, machining by the first punch and machining by the second punch are performed individually.

Abstract: A carrier device is provided that can supply, at uneven intervals, a plurality of works arranged at even intervals. The carrier device (1) includes: a first retaining portion (11), second retaining portion (12), third retaining portion (13) and fourth retaining portion (14) that hold and carry a plurality of works arranged at even intervals and supply these to a supply pallet (7) at any intervals; and a retaining base portion (20) to which these first to fourth retaining portions are connected. The retaining base portion (20) includes first to fourth sliding portions that cause the first retaining portion (11) to fourth retaining portion (14) to approach each other or separate in the arrangement direction of the works. The first retaining portion (11) to fourth retaining portion (14) respectively include first engaging parts and second engaging parts that disengage with the works independently.

Abstract: A machine tool has a Z table sliding in the Z direction in a horizontal plane, a support body provided on the Z table and sliding in the vertical direction, a rotation arm supported at the support body and endlessly rotatable in a vertical plane facing work, an arm motor for rotating the rotation arm, a processing spindle rotatably supported and placed at a position of a distance R from the center C of rotation of the rotation arm, and a spindle motor for rotating the processing spindle.

Abstract: A part assembling apparatus is provided with a plurality of assembling portions and a ball screw shaft. Each of the assembling portion includes a nut runner for assembling a part to an assembling target. The ball screw shaft includes a thread portion. At least two of the plurality of assembling portions respectively include nut portions threadedly engaged with the thread portion. The nut portions are movable in an axial direction of the ball screw shaft. The thread portion includes a first thread part having a first pitch and a second thread part having a second pitch different from the first pitch.

Abstract: A bolt supply apparatus (1) recognizes images of bolts conveyed by a conveyor (22) using a camera (24) and feeds the recognized bolts to a next operation step using a robot (26). Bolts to be conveyed from a hopper (10) through a spiral feeder (14) are temporarily stored in a first storage box (16). Weight of the first storage box (16) is measured by a first weight measuring device (18). When the first weight measuring device (18) measures a given weight, the bolts of the first storage box (16) are supplied to the conveyor (22).

Abstract: A cutting pallet is provided that can prevent works held in a carrier device from interfering with a supply pallet, when a plurality of works arranged at even intervals is supplied at uneven intervals. The cutting pallet (6) in which a plurality of works (W) to be carried by the carrier device (1) is arranged is provided with a plurality of cutting pallet holes (61a, 61b, 62a, 62b, 63a, 63b, 64a and 64b) arranged at even intervals and to which a plurality of works W is inserted and removed, respectively. Among the plurality of cutting pallet holes (61a, 61b, 62a, 62b, 63a, 63b, 64a and 64b), the depths of holes adjacent to each of are different from each other.

Abstract: A multi-spindle head exchangeable machine tool is provided with a plurality of multi spindle heads movably mounted on an annular rail. When a workpiece is machined by driving a rotary tool by a machining unit, multi spindle heads of the plurality of multi spindle heads being out of use can be separated from the machining unit. Further, a connecting device is provided with an inner slider, ball bearings fitted to an outer periphery of the inner slider, an outer slider, and a coil spring to press the outer slider toward a stopper member.
