Lathe tool mounting expander
First Claim
1. A lathe tool mounting expander assembly, said assembly being actuated by hydraulic fluid, said assembly comprising:
- (a) a block having a base, an inner end, an outer end, a compression end, and a compression face;
(b) a first cylindrical void extending into the block, the first cylindrical void having a planar floor, said void opening at the block'"'"'s compression end;
(c) a second cylindrical void extending into the block, the second cylindrical void having a wall and a floor, said void opening at the block'"'"'s outer end;
(d) first and second pistons respectively slidably mounted within the first cylindrical void and the second cylindrical void;
(e) a conduit extending between the first cylindrical void and the second cylindrical void, the conduit being adapted for conveying the hydraulic fluid from the second cylindrical void to the first cylindrical void;
(f) a jack screw actuator connected operatively to the block, the jack screw actuator being adapted for driving the second piston against the hydraulic fluid, the hydraulic fluid, upon such piston driving, flowing through the conduit and moving the first piston; and
(g) a plurality of third cylindrical voids and a plurality of third pistons, each void among the plurality of third cylindrical voids opening at the block'"'"'s compression end and having a planar floor wherein the third pistons are respectively slidably received within the third cylindrical voids, wherein the conduit is adapted for further conveying the hydraulic fluid to the third cylindrical voids, wherein each cylindrical void among the first cylindrical void and the plurality of third cylindrical voids has a base end, wherein the conduit comprises a plurality of shunts having planar floors, wherein each shunt is hourglass shaped, wherein each shunt opens at the base ends of an adjacent pair of voids among the first cylindrical void and the plurality of third cylindrical voids, and wherein each planar floor among the first cylindrical void'"'"'s planar floor, the third cylindrical voids'"'"' planar floors, and the shunts'"'"' planar floors is coplanar with each other planar floor among said planar floors.
