<p>This invention relates to a pallet exchanger used for machine tools. A conventional pallet exchanger requires a large-sized hydraulic cylinder which inevitably imparts an impact to a pallet and a work. The present invention eliminates this drawback. The present invention is provided with a mount (60) having guide means (81, 82) and a plurality of pallets (30, 50) thereon, a table (26), a support (61) and a transfer means (62). The transfer means (62) is provided with a driving means (65) set on the support (61), and operating means (66, 67) adapted to be turned by this driving means (65). One end of each of the operating means (66, 67) is joined to each of the respective guide means (81, 82) on the mount (60). Owing to an operation of the driving means (65), these ends of the operating means (66, 67) are turned forward and backward within the range of predetermined angles around the other ends thereof. This enables the mount (60) to be moved from the support (61) to the table (26), and vice versa.</p> |
