Abstract
Machine tool, comprising a workpiece carrier assembly (11) including a workpiece carrier (12), said workpiece carrier assembly (11) being supported on a workpiece carrier support (1) for horizontal movement in a first direction in parallel with a horizontal Z axis; a first tool carrier (21), supported on a tool carrier support (2) for horizontal movement in a second direction, said first tool carrier (21) being displaceable in said second direction between an operative position in which said first tool carrier (21) is facing said workpiece carrier assembly (11), and an inoperative position in which said first tool carrier (21) is not facing the workpiece carrier assembly (11). The invention also relates to a method of machining a connecting rod using the machine tool.
Claims15
A machine tool for machining connecting rods for a reciprocating piston engine, the machine tool comprising:
- a workpiece carrier assembly (11) including a workpiece carrier (12), the workpiece carrier (12) supporting a plurality of connecting rod workpieces (1000);
- a workpiece carrier support (1), supporting the workpiece carrier assembly (11) for horizontal movement thereon in a first direction parallel with a horizontal Z axis;
- a first tool carrier (21) having a plurality of spindles, the plurality of spindles carrying a first plurality of tools (102, 103) for simultaneously machining the plurality of connecting rod workpieces (1000) by rotating the first plurality of tools (102, 103) around an axis parallel with the Z axis;
- a tool carrier support (2), supporting the first tool carrier (21) for horizontal movement in a direction parallel with a horizontal X axis, perpendicular to the Z axis;
- the first tool carrier (21) being laterally displaceable on the tool carrier support (2) with respect to the workpiece carrier assembly (11) between an operative position in which each of the first plurality of tools (102, 103) are capable of contacting the plurality of connecting rod workpieces (1000) and an inoperative position, laterally offset from the workpiece carrier assembly (11), in which the plurality of connecting rod workpieces (1000) are not contactable by the first plurality of tools (102, 103),
- a second tool carrier (22), having a plurality of spindles, the plurality of spindles carrying a second plurality of tools (100, 101) for simultaneously machining the plurality of connecting rod workpieces (1000) by rotating the second plurality of tools (100, 101) around an axis extending parallel with the Z axis,
- the second tool carrier (22) supported on the tool carrier support (2) for horizontal movement in a direction parallel with the horizontal X axis, perpendicular to the Z axis;
- the second tool carrier (22) being laterally displaceable on the tool carrier support (2) with respect to the workpiece carrier assembly (11) between an operative position in which each of the second plurality of tools (100, 101) are capable of contacting the plurality of connecting rod workpieces (1000) and an inoperative position, laterally offset from the workpiece carrier assembly (11), in which the plurality of connecting rod workpieces (1000) are not contactable by the second plurality of tools (100, 101).
