Abstract

A rotary mechanism of a machine tool (driving device 10) includes a first motor 60 for carrying out rotary driving and positioning of a workpiece support (rotary stacking-receiving die assembly 32), and second motors 62, 63 for supplementing rotation of the rotary stacking-receiving die assembly. The stop positioning accuracy of the rotary stacking-receiving die assembly 32 due to the second motors 62, 63 is lower than the stop positioning accuracy of the rotary stacking-receiving die assembly 32 due to the first motor 60.

Description

technical field [0001] The invention relates to a rotary mechanism for rotatably driving a workpiece support, which supports a workpiece in a machine tool. Background technique [0002] The rotor core of the electric motor is configured in the same annular shape (cylindrical shape) by, for example, stacking a plurality of thin steel plates forming an annular shape. For this purpose, each thin steel plate in an annular shape is cut out from the plate material, the inner peripheral portion of which is not used. Therefore, in order to improve the utilization rate of the plate material, a rotor core made of a plurality of divided core plates each formed of a sector-shaped thin steel plate obtained by dividing a ring-shaped thin steel plate in the circumferential direction is employed. . [0003] As for this type of rotor core, the present inventors have proposed a manufacturing method and apparatus for a rotor core (annular core) in which the rotor core is formed by stacking s...
