Abstract
In a tool pivot unit with a pivot head which is disposed in a housing and in which a drivable tool holder is supported so as to be rotatable by at least 100 degrees about a pivot axis which extends transverse to the movement direction of the machine tool carriage, the pivot head is movable with respect to the housing by means of a drive, which converts a linear movement into a pivot head rotation. The drive includes a linear carriage, which for inducing the movement, the linear carriage contacts at least one stop, while the housing is moved relative to this stop by the machine tool carriage and the machine tool table.
Claims9
A tool pivot unit for the replaceable installation in an exchange adapter (4) of a movable machine tool carriage (2) including a pivot head (50) supported in a housing (11) in which a rotatable tool holder (70) is operably arranged, the pivot head (50) being supported in the housing (11) so as to be pivotable by at least 100 angular degrees about a pivot axis (52) which extends transverse to the direction of travel (3) of the machine tool carriage (2),
- the pivot head (50) being movable relative to the housing (11) by means of a drive (30, 40) which converts a linear movement into a pivot head rotation,
- the drive (30, 40) including a linear carriage (31, 41), and,
- for a displacement of the linear carriage (31, 41) relative to the housing (11) the linear carriage (31, 41) upon placement thereof into contact with at least one stop (83, 81), being held stationary by said stop while the housing (11) is moved relative to this stop (83, 81) by means of one of one of the machine tool carriage (2) and the machine tool table 8, or
- the linear carriage (31, 41) comes into contact with a stop which is movable by a motor for moving the linear carriage linearly with respect to the stationary housing (11).
A machine tool pivot unit for the replaceable installation in an exchange adapter (4) of a machine tool carriage (21) provided with an operating shaft (5), including a housing (11) which is pivotable with respect to the machine tool carriage (2) about the centerline (19) of the operating shaft (5), a pivot head (50) which is supported in the housing (11) and in which a drivable and rotatable tool holder (70) is arranged, the pivot head (50) being pivotable in the housing (11) by at least (100) angular degrees about an axis (52) which extends transverse to the centerline (19) of the operating shaft (5),
- the housing (11) as well as the pivot head (50) is movable about the respective pivot axis (19, 52) by means of a drive (30, 40),
- which includes a linear carriage (31, 41) which is force-coupled to a drive wheel, and,
- for adjustment of the respective linear carriage (31, 41) it is in contact with at least one stop (83, 81) while the housing (11) is moved relative to this stop (83, 81) by means of one of the machine tool carriage (2) and the machine tool table (8).
