HYDRAULIC FASTENING OF COMPONENTS

摘要

A hydraulic fastening device for securement of two components together, each component having an orifice or cavity at least partly there through adapted to be substantially coaxially aligned, the fastening device including a body member adapted to be inserted substantially within the orifice or cavity of each component when substantially coaxially aligned. The body member include s a main body section and a hydraulic manifold section with a fluid conduit within at least the manifold section and containing a fluid therein. The device further includes at least one moveable protrusion means in fluid contact with the fluid, adapted to protrude from the manifold section; and control means to control the movement of the or each protrusion means. The arrangement is such that, upon operation of the control means, the or each protrusion means is moved between a protruding position and a retracted position and when in the protruding position the two components are adapted to be fastened or locked together.
