"Family Of Attachment Devices With Variable Taper"

Abstract: Family of attachment devices with variable taper In the prior art, a multitude of families of different drills and lengths exist, varying per diameter of the attachment, contrary to attachments with cylindrical bodies, for which a single tool is sufficient. One of ordinary skill in the art must provide for the appropriate tool and device for each thickness of the element being fastened, which represents a significant cost in tooling, in addition to a loss of the time required to change the tooling. The invention relates to the idea of adapting the rate of taper (C1; C2) of the device (1; 20) according to the thickness being fastened (12; 31). Preferably, the rate of taper of the bushings falls between 1% and 4%. Thus, with three or four reference clearances for devices with the same outer diameter (16A; 16C), however a different rate of taper, all conceivable element thicknesses can be fastened, without modifying the diameter of the bore made within the elements being assembled.
