FAMILY OF FIXATION DEVICES WITH VARIABLE TAPER
According to the prior art, there is a multiplicity of drilling and length families by fixation diameter recognition, contrarily to cylindrical smooth portion fixations for which a single tool is not sufficient. The person skilled in the art must plan the adequate tool and device for each thickness of a member to be clamped, which represents an important tool cost and also a time loss due to the change of tools. The purpose of the invention is to adapt the taper ratio (C1; C2) of the device (1, 20) based on the thickness to be clamped (12, 31). Preferably, the taper ratio of the bushings ranges between 1 and 4 %. Accordingly, using three to four reference sets of devices having the same outer diameter (16A, 16C) but a different taper ratio, it is possible to clamp any potential member thickness with modifying the bore diameter of members to be assembled.
