A centering device (1) for the guided transfer of bars from a feeder (F) to a lathe (3), and interposed therebetween aligned with a bar guide (4) with the mandrel of the lathe (3), comprising: a bush (5) for fixing to a fixing seat (6) and rigidly coupled to a bar opening (2) aligned with the respective bar guide (4) and with the mandrel of the lathe (3); a tubular body (7), rigidly coupled to the bush (5) coaxial thereto and provided with a housing seat (8) for a ring (9) with oscillating elements which are pivoted to a respective fixed anchoring element (11) with one end and are retained in mutual contact by elastic elements (12), delimiting a through opening whose diameter is about as long as the diameter of a bar. The ring (9) and the anchoring element (11) are axially movable within the seat (8), in contrast to springs (13) toward the lathe (3). |
