Description

[Brief explanation of the drawing]

FIG. 1 is a partially cross-sectional front view of the entire tapered surface processing apparatus which is an embodiment of the present invention.
FIG. 2 is a front sectional view showing the tip of the main shaft of the processing device. FIGS. 3 to 5 are diagrams conceptually representing the sliding direction of the traverse slider for each inclination angle of the tapered surface when forming the tapered surface using the processing apparatus described above. FIGS. 6 to 8 are diagrams illustrating the process of removing the cutting tool body, sliding shaft, and reamer shaft from the main shaft. FIG. 9 is a front sectional view showing the cutting tool body, sliding shaft, and reamer shaft removed from the main shaft, and FIG. 10 is a front sectional view showing the main shaft from which these have been removed. FIG. 11 is a front sectional view showing a state in which the sliding shaft and the sliding shaft joint are connected by fitting a steel ball into an annular groove. 10: Main shaft, {18: Pulley, 20: Spindle motor, 22: Pulley, 24: Belt} (rotary drive device), {32: Nut, 34: Electric motor (NC motor), 36: Feed screw} (Spindle feed) device), 58: Sliding shaft, 82: Moving metal (motion conversion mechanism), {88: Nut, 92: Electric motor (NC

Claims (1)

[Claims for Utility Model Registration] A hollow main shaft that is rotated by a rotary drive device and fed in the axial direction by a main shaft feeding device, and a shaft that cannot rotate relative to the main shaft within the hollow of the main shaft. a sliding shaft disposed so as to be relatively movable in the direction; a sliding shaft feeding device for feeding the sliding shaft in the axial direction; and a sliding shaft feeding device attached to the tip of the main shaft,
A cutting tool main body that holds a traverse slider holding a cutting tool so as to be slidable in a direction having a component perpendicular to the axis of its main shaft, and a cutting tool body provided between the sliding shaft and the traverse slider, A tapered surface machining device including a motion conversion mechanism that converts an axial motion of a driving shaft into a sliding motion of a traverse slider, the main shaft feeding device and the sliding shaft feeding device both having a feed screw and the feed screw. A numerically controllable electric motor for rotational driving is included, and a numerical control device for the two electric motors is configured to simultaneously rotate the two electric motors at arbitrarily set rotational speeds. Features a tapered surface processing device.
