<p>A table-changing device for a machine for working parts comprises at least two working tables (2, 3) of which a first table (3) is slidably supported by substantially rectilinear first rails (9) so as to move from a first position of working to a second position of loading and unloading and vice versa translating horizontally, while a second table (2) is slidably supported by second and third shaped rails (24, 25) provided with inclined portions (28, 30; 29, 31), fixed in respect of the first rails (9). In this way the second table (2) moves from the second position of loading and unloading to the first position of working and vice versa sliding on the second and third shaped rails (24, 25), first lowering itself below the first table (3) and then raising itself to the height of the first table (3), remaining horizontal. <IMAGE></p> |
