Abstract
An APC is provided in a five-axis controlling vertical machining center. A spindle head is movable in three mutually transverse axes directions to a workpiece. A table disposed below swings to be positioned and is directed upwardly and indexed. A pallet setup base is provided outside a machining area. A pallet change arm has pallet grip portions for gripping and releasing the pallets. The arm makes a swivel motion and makes an ascending and descending motion. Thus, the pallet is transferred between the table and the pallet setup base and is received and discharged to the table and the pallet setup base.
Claims11
A pallet changer, for changing pallets, provided on a machine tool being a five-axis controlling machine tool, said machine tool comprising:
- a spindle head being movable in three mutually transverse axes directions relative to a workpiece supported by a pallet mounted on a table;
- and
- said table disposed below a level of said spindle head, said table is driven by a table drive unit so that said table is swingable and positioned while being directed in an upward direction and also making at least an index motion, wherein said table as driven by said table drive unit is also capable of making rotational motion as well as the index motion,
- said pallet changer comprising:
- a pallet setup base, provided outside a machining area of said machine tool, for placing the pallet on said pallet setup base;
- and
- a pallet change arm, which is provided with at least one pallet grip portion for gripping and releasing the pallet, for making a swivel motion substantially in a horizontal plane and for moving up and down,
- wherein said pallet change arm makes the swivel motion and moves up and down so that the pallet is transferred between said table and said pallet setup base and is received and discharged to said table and said pallet setup base, respectively.
A machine tool provided with a pallet changer, said machine tool being a five-axis controlling machine tool comprising:
- a spindle head being movable in three mutually transverse axes directions relative to a workpiece supported by a pallet mounted on a table;
- and
- said table disposed below a level of said spindle head, said table is driven by a table drive unit so that said table is swingable and positioned while being directed in an upward direction and also making at least an index motion, wherein said table as driven by said table drive unit is also capable of making rotational motion as well as the index motion,
- said pallet changer comprising:
- a pallet setup base, provided outside a machining area of said machine tool, for placing the pallet on said pallet setup base;
- and
- a pallet change arm, which is provided with at least one pallet grip portion for gripping and releasing the pallet, for making a swivel motion substantially in a horizontal plane and for moving up and down,
- wherein said pallet change arm makes the swivel motion and moves up and down so that the pallet is transferred between said table and said pallet setup base and is received and discharged to said table and said pallet setup base, respectively.
A pallet changer, for changing pallets, provided on a machine tool being a five-axis controlling machine tool, said machine tool comprising:
- a spindle head being movable in three mutually transverse axes directions relative to a workpiece supported by a pallet mounted on a table;
- and
- said table disposed below a level of said spindle head, said table is driven by a table drive unit so that said table is swingable and positioned while being directed in an upward direction and also making at least an index motion,
- said pallet changer comprising:
- a pallet setup base, provided outside a machining area of said machine tool, for placing the pallet on said pallet setup base;
- and
- a pallet change arm, which is provided with at leat one pallet grip portion for griping and releasing the pallet, for making a swivel motion substantially in a horizontal plane and for moving up and down,
- wherein said pallet change arm makes the swivel motion and moves up and down so that the pallet is transferred between said table and said pallet setup base and is received and discharged to said table and said pallet setup base, respectively, and
- wherein said pallet change arm which is moved up and down ascends up to a predetermined lifted position, while said pallet change arm makes the swivel motion and is under a standby condition, so that said pallet change arm does not interfere with other structural components of said machine tool.
A machine tool provided with a pallet changer, said machine tool being a five-axis controlling machine tool comprising:
