Patent ID: 8123594

Claim:
A post shaving orbital system for blind bolt fasteners, being intended for the elimination of edges and burrs generated in a threaded pin of a fastener, following shaving or cutting of surplus corresponding to said pin the system comprising: a headstock with a coupling cone for coupling the system to a drive unit; the coupling cone being connected to a shaft with means for producing an orbital rotation which, in combination with a spring which allows an upward/downward axial displacement of the shaft, establishes the adaptation, of a plate for carrying an abrasive disc, to a surface of a body in which said pin is fitted, so that the pin, previously shaved, is sanded on said surface of the body; said plate being coupled to a lower end of the shaft; wherein the rotating shaft is guided on a polygonal collar, which permits axial displacement of said shaft and produces a pulling and corresponding rotation of the latter in the rotary motion of the coupling cone to which it is connected.
