Workpiece transfer device for machine tools

摘要

A workpiece transfer device for machine tools that easily achieves positional adjustment of the rack while suppressing increases in cost and therefore preventing occurrences of vibrations and noise is disclosed. The workpiece transfer device includes a frame member having a rectangular cross-section. The device extends from a workpiece machining position to a workpiece loading/unloading position. A support member is hung on the frame member so as to be movable via a linear guide and which has a workpiece holding mechanism mounted thereon. A drive mechanism for rotationally driving a pinion gear engaged with a rack is provided on the frame member so as to be parallel to the linear guide so that the support member is moved between the two positions. The linear guide is disposed on one wall of the frame member and the rack is disposed on another wall surface so as to have its position adjustable.
