Claims

[Scope of utility model registration request]

A housing is provided on the base of a machine tool so as to be horizontally movable in the front and back and left and right directions, an input shaft is rotatably supported by this housing, a globoidal cam is integrally attached to this input shaft, and this A cam follower engaged with a tapered rib of a globoidal cam, a turret in which a plurality of cam followers are provided radially at predetermined intervals, and an output shaft to which the turret is integrally attached and rotatably supported by the housing. It has a rotary disk attached to the shaft end of the output shaft, and a plurality of blades held at the periphery of the rotary disk, and the predetermined blades are positioned and fixed at the workpiece processing position during machining. In the tool indexing machine of a machine tool, each support part of the turret for fixing the cam follower is made to protrude outward in the radial direction to form a recessed part through which the tip of the tapered rib is inserted between each support part, Between both side wall surfaces of the support portion and both side wall surfaces of the tapered rib, when the cam follower is deformed due to a load acting between the cam follower and the taper rib, the support portion is provided within an elastic deformation region of the deformation. A tool indexing machine for a machine tool, characterized in that a minute gap is provided between the side wall surface of the tapered rib and the side wall surface of the tapered rib.
