Abstract

EL DISPOSITIVO PARA REALIZAR TALADROS DE DESPULLA EN UN FONDO TIENE UN CASQUILLO DE GUIA (2) Y UN CASQUILLO EXCENTRICO (4) QUE SE PUEDE GIRAR RELATIVA AL CASQUILLO DE GUIA. ENTRE EL CASQUILLO DE GUIA (2) Y EL EXCENTRICO (4) SE ENCUENTRA UN MUELLE DE TORSION (6). EN LA TORSION RELATIVA DEL CASQUILLO EXCENTRICO (4) FRENTE AL CASQUILLO DE GUIA (2) SE TENSA EL MUELLE DE TORSION (6). AL MISMO TIEMPO SE COLOCA EL EJE MOTRIZ (8) CON EL CABEZAL DE CORTE (9) EN POSICION EXCENTRICA Y SE REALIZA LA ENTRADA EN LA PARED DEL TALADRO. UN BLOQUEO QUE ACCIONA SOBRE UN DENTADO (2A) IMPIDE QUE SE MUEVA TAMBIEN EL CASQUILLO DE GUIA (2). CUANDO EL EJE MOTRIZ (8) HAYA LLEGADO A LA EXCENTRICIDAD MAXIMA SE SUELTA EL BLOQUEO Y SE TUERCE EL CASQUILLO DE GUIA (2) JUNTO CON EL CASQUILLO EXCENTRICO (4) MEDIANTE UN ENGRANAJE EXCENTRICO. EN ELLO, EL CABEZAL DE CORTE (9) CREA UNA DESPULLA EN LA PARED DEL TALADRO. AL TERMINAR UN GIRO COMPLETO, EL MUELLE DE TORSION (6) SE DESTENSA Y EL CASQUILLO DE GUIA (2) SE TUERCE RELATIVO AL CASQUILLO EXCENTRICO (4) DE FORMA QUE EL EJE MOTRIZ (8) VUELVE DE NUEVO A LA POSICION CENTRICA.
