2. A Semi-concealed casebound wire journal cover comprising the combination of a cover having a cover sheath and a liner and a set of panel stiffeners between including a front cover panel stiffener, a spine panel stiffener, and a rear cover panel stiffener, comprising a first section hingedly attached to a second section, hingedly attached to a third section, which is hingedly attached to a fourth section, wherein the first section is a front cover portion comprised of a panel stiffener glued between the cover sheath and the liner, the second section is a second front cover portion comprised solely of a glued liner and cover sheath, a third section is a spine section of predetermined width substantially the diameter of a predetermined wire spine to be contained therein, comprised of a spine panel stiffener glued between said liner and said cover sheath, and a fourth section as a rear cover comprising a rear cover panel glued between said liner and said cover sheath, wherein a series of hinges is thereby formed between said front cover panel, said second front cover portion, said spine, and said rear cover where said hinges comprise the glue line formed between said liner and said cover sheath between any of said panel stiffeners, and where said hinges so formed provide substantially zero resistance to the turning of the covers from full open to full folded back positions, in combination with a wire ring of predetermined width, wherein said leaves are of a predetermined width such that said leaves fit within said covers when said wire ring is attached to said front cover, said leaves attached to said wire, and said covers are closed.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A tool turret, comprising:
a base body mountable to a machine tool and defining a turret axis;
a tool disk pivotably mounted on the base body, being pivotable about said turret axis and having a tool disk periphery;
a plurality of tool stations distributed on said tool disk periphery and being movable to at least one working position at a time by pivoting said tool disk about said turret axis;
a tool drive located within said tool disk and having an output-side gear part rotatable around a radial axis of rotation radial to said turret axis, said output-side gearing part being couplable to a tool-side coupling part for driving at least one tool located on the tool station aligned to the at least one working position; and
a clutch in said tool disk, said clutch being switchable between a first operating position in which said output-side gear part pivots with said tool disk around the turret axis and is connected to said tool disk, and a second operating position in which said output-side gear part is decoupled from said tool disk so as not to pivot with said tool disk around said turret axis during rotation of said tool disk around said turret axis.
2. The tool turret according to claim 1, wherein
said clutch has a bushing as a movable coupling part, said bushing forming a rotary support of said output-side gear part for rotation of said output-side gear part around said radial axis of rotation; and
said bushing is movable in said tool disk in a direction of said radial axis of rotation between the first operating position and the second operating position, in the first operating position, said bushing being in a radially advanced position in which end-side drivers of said bushing engage driver surfaces of said tool disk.
3. The tool turret according to claim 2, wherein
said output-side gear part, as a further component of said clutch, together with said bushing is radially movable in the direction of said radial axis of rotation in said tool disk; and
said output-side gear part, in the second operation position, has been moved to a position shifted radially with respect to said turret axis to the inside of said tool turret, in which radially inside position the output-side gear part is secured on said base body against pivoting motion around said turret axis.
4. The tool turret according to claim 3, wherein
said tool drive comprises an angle drive with a drive-side crown gear rotatable around said turret axis and having teeth lying in a plane extending radially relative to said turret axis, said teeth having a radial extension such that teeth of said output-side gear part remain engaged with said teeth of said crown gear when said output-side gear part is in both of said first and second operating positions.
5. The tool turret according to claim 3 wherein
said base body has a central support column defining said turret axis, said tool disk being pivotable about said control support column; and
a guide body is within said tool disk, said bushing and said output-side gear part supported in said bushing are guided both for radial movements of said bushing and said output-side gear part in the direction of said radial axis of rotation between the first and second operating positions and for pivoting movements of said bushing and said output-side gear part around said turret axis.
6. The tool turret according to claim 5, wherein
in the second operating position of said clutch, a flattened part of the output-side gear part extends through a passage of the guide body to press onto flattened end sections of said support column, fixing said guide body in an angular position thereof with respect to said turret axis.
7. The tool turret according to claim 5, wherein
a drive-side crown gear of said tool drive is mounted on a hollow shaft surrounding said support column.
8. The tool turret according to claim 7, wherein
to fix the rotary position of the tool disk about said turret axis, a clamping mechanism between said base body and said tool disk fixes rotary positions of said tool disk.
9. The tool turret according to claim 2, wherein
an outer peripheral side of the bushing has a projecting ring body acting as a movable annular piston and separating pressure chambers from one another made in a guide section on which said bushing is guided during for displacement motions of said bushing between the first and second operating positions, said pressure chambers being selectively supplied with hydraulic medium.
10. The tool turret according to claim 1 wherein
said clutch is moved into the first and second operating positions using a hydraulic actuator.
11. The tool turret according to claim 1, wherein
a drive for pivoting motions of said tool disk is around and coaxial to said turret axis, said drive comprising a torque motor having an outer rotor connected to said tool disk for direct driving of said tool disk.
