Abstract

Abstract The device permits of grasping, centering automatically and aligning the longitudinal axis of a long body in particular of a pen body according to the working axis (B) or corresponding to the following operation carried out on a machine tool which is preferably automatic. It comprises a toggle lifting mechanism (6, 7, 8, 9) provided with grasping jaws (8', 9') for the long body, jaws made angled by which grasping the long body they determine the movement of translation until they bring the longitudinal axis (A) of the grasped body into the exact position of centering and alignment with the working axis (B) or corresponding to the following operation. A piston operated pneumatically or in another manner permits moving the lever mechanism closing it on the long body opposing a spring (12).

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 199 words
A device for grasping and centering automatically long bodies, comprising a support (4) having a slot (16) therein, a fulcrum pivot (10) slidable in the slot (16), a pair of elongated jaws (8,9) pivoted intermediate their ends on the pivot (10), toggle levers (6,7) pivoted one on one end of each of said jaws (8,9), a common pivot (5) interconnecting said toggle levers (6,7) at ends of said levers remote from said jaws (8,9), and means (1-3) for forcing said common pivot (5) in a direction (13) in alignment with the length of said slot (16) and toward a said body to be grasped, said levers and jaws being so disposed that said jaws close toward each other when said fulcrum pivot reaches the end of said slot nearest said body and movement of said common pivot in said direction thereafter continues, said grasping jaws having inner angled faces (8', 9') on their ends remote from said toggle levers (6, 7), said inner angled faces (8', 9') providing a V-shaped recess on said remote end of said grasping jaw (8, 9), said recesses opening toward each other for closing on and automatically centering and grasping a said long body.
