A workpiece conveying apparatus of a machine tool, capable of covering a workpiece moving mechanism based on a simple structure and thereby preventing the entire machine from increasing in size is provided. A frame memberis formed by a pipe body extending from a workpiece machining position A to the vicinity of a workpiece carry-in-and-out position B, and the workpiece moving mechanismis structured that a beltis wound around a driving pulleyand a driven pulleyto drive the driving pulleyto rotate by a driving motorwhere the beltis arranged in the accommodated state in the frame member

Workpiece conveying apparatus of machine tool

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.

Workpiece transfer device for machine tools

A machine tool has a pallet changer at a front of a machine body for automatically changing a preceding-process pallet loaded with a machined workpiece thereon for a next-process pallet loaded with an unmachined workpiece thereon. A working space is provided between the machine body and the pallet changer. Thus, a machine tool, as well as a pallet changer used in the machine tool can be provided that allows a working space to be ensured without causing any complications for the structure and that has a wide range of applications.
