Abstract

A clamp (1000) designed to axially block an axisymmetric body (CA) by applying radial actions (forces) and provided with a plurality of gripping devices (1) distributed concentrically around an axis (AX) and developed along a given direction (D) to apply radial actions (forces) centered on said central axis (AX); each device (1) comprising a support assembly (10) and a gripping assembly (20) coupled by means of a plate (22) that supports at least one holding unit (200) at the front; each holding unit (200) comprising at least one toothed sliding block (202) carried in a freely rotatable and axially fixed way and axial-hinge coupling members (30) arranged between the plate (22) and each sliding block (202) and distributed along the direction (D).

Dependent claims

A gripping device (1) for a clamp (1000) having a central axis (AX) and designed to axially block an axisymmetric body (CA) by applying radial actions centred on said central axis (AX);

said device extending in a given direction (D) parallel to said axis (AX) and comprising a support assembly (10) and a gripping assembly (20) coupled together by means of a plate (22) that delimits said gripping assembly (20) at the rear and supports, at the front, at least one holding unit (200);
each said holding unit (200) comprising at least one toothed sliding block (202) carried in a freely rotatable and axially fixed way with respect to said direction (D);
where each said holding unit (200) comprises hinge coupling means (30) axially distributed along said direction (D) and arranged between said plate (22) and each said sliding block (202), characterized in that said coupling means (30) comprise tabs (32) carried at the front by said plate (22) and abutment elements (34) carried at the rear by said sliding block (202) and shape-fitted to said tabs (32).

Dependencies are inferred from the claim text.
