Abstract
A central pillar (20) is projected upward from a reference block (1), and an inner sleeve (21) is fitted to an outer periphery of the central pillar (20) vertically movably. The inner sleeve (21) is pushed upward by a coned disc spring (25). An outer sleeve (31) to be inserted into a socket hole (3) of a movable block (2) makes a tapering engagement with the inner sleeve (21) from above. The inner sleeve (21) and the outer sleeve (31) are adapted to be diametrically expandable and contractible. An output member (36) is inserted into the central pillar (20), and an upper portion of the output member (36) is connected to the outer sleeve (31). A driving mechanism (D) in the reference block (1) moves the outer sleeve (31) downward for locking via the output member (36).
Claims25
A clamping apparatus, wherein
- An annular central pillar (20) is projected from a reference block (1) toward a leading end,
- an inner sleeve (21) is fitted onto the central pillar (20) axially movably within a predetermined range, and the inner sleeve (21) is advanced toward the leading end by a predetermined advancing stroke by an advancing means (25),
- an outer sleeve (31) to be inserted into a socket hole (3) of a movable block (2) makes a wedge engagement with the inner sleeve (21) from the leading end side, and the outer sleeve (31) is adapted to be diametrically expandable and contractible,
- an output member (36) is inserted into a cylindrical hole (20a) of the annular central pillar (20) axially movably, and a leading end portion of the output member (36) is connected to the outer sleeve (31),
- a locking means (51) and a releasing means (52) are provided in the reference block (1), the locking means (51) moves the outer sleeve (31) toward a base end for locking via the output member (36), while the releasing means (52) moves the outer sleeve (31) toward the leading end for releasing via the output member (36).
A clamping apparatus, wherein
- an annular central pillar (20) is projected from a reference block (1) toward a leading end,
- an inner engaging member (21) is arranged on an outer periphery of the central pillar (20),
- an outer engaging member (31, 72) to be inserted into a socket hole (3) of a movable block (2) is diametrically expandable and contractible, the outer engaging member (31, 72) makes a wedge engagement axially with the inner engaging member (21), and the outer engaging member (31, 72), which is in the wedge engaged state, is movable toward a base end and diametrically expandable for locking,
- an output member (36) is inserted into the annular central pillar (20) axially movably, and an output portion of the output member (36) is connected to either the outer engaging member (31, 72) or the inner engaging member (21),
- an input portion of the output member (36) is connectable to a driving means (D).
