ROTARY WORKHEAD DEVICE

摘要

The rotary workhead device, which is loaded on the table of a machine tool and onto which a workpiece to be machined is rotatably mounted, is equipped with: a base plate that is attached to the table of the machine tool; two rotary workheads that are provided on the base plate and disposed so that the axes of rotation coincide and the workpiece-fixing parts face each other; a guide means that is provided so as to be capable of moving at least one of the rotary workheads back and forth in the direction of the rotation axes; and an impelling means for impelling the one rotary workhead in a direction that separates or brings together the two rotary workheads. The rotary workhead device applies a tensile force or a compressive force on a workpiece, the respective ends of which are fixed between the two rotary workheads.

主权项

1. A rotary workhead device, disposed on a table of a machine tool, for rotatably mounting a workpiece to be processed, comprising:
a base plate adapted to be secured to the table of the machine tool; two opposing rotary workheads disposed on the base plate so as to align the respective rotational axes with each other; guide means for allowing at least one of the rotary workheads to reciprocally move in the direction of the rotational axes; and biasing means for biasing one of the rotary workheads in the direction away from or toward the other of the rotary workheads; wherein a tensile or compressive force is applied to the workpiece secured at its ends between the two rotary workheads.
