Abstract

SE DISPONE UN APARATO DE AMARRE (35) PARA UNIR DE FORMA SEPARABLE UNA UNIDAD DE HERRAMIENTA (10) A UN CABEZAL PORTAHERRAMIENTAS (37), CON FUERZA DE SUJECION INCREMENTADA. EL APARATO DE AMARRE (35) INCLUYE UNA CARCASA (41), UN PAR DE ESFERAS BLOQUEANTES ENFRENTADAS (57A, B) DENTRO DE LA CARCASA (41), UN MIEMBRO DE CAJA CILINDRICO (39) MONTADO DENTRO DE LA CARCASA (41), QUE SE ACOPLA CON UNA UNIDAD DE HERRAMIENTA INSERTABLE DE SOPORTE, Y QUE TIENE UN PAR DE ABERTURAS OPUESTAS (55A, B) EN SUS LATERALES, PARA DIRIGIR LAS ESFERAS BLOQUEANTES (57A, B) DESDE UNA SITUACION DE BLOQUEO A UNA DE DESBLOQUEO, Y UNA BARRA DE BLOQUEO (60) MUTUAMENTE DESPLAZABLE EN EL INTERIOR DEL MIEMBRO DE CAJA (39) A LO LARGO DE UN EJE (A), Y QUE TIENE TRAMOS DE LEVA ENFRENTADOS (64A, B) PARA MOVER RADIALMENTE LAS ESFERAS BLOQUEANTES (57A, B) A TRAVES DE LAS ABERTURAS DEL MIEMBRO DE CAJA (55A, B) A UN AJUSTE CHAVETEADO CON PAREDES ENFRENTADAS EN ANGULO (30), DE ABERTURAS ESFERICAS DE ACOGIDA (20) DE LA UNIDAD DE HERRAMIENTA (10). PARA INCREMENTAR LA VENTAJA MECANICA DE LA ACCION DE ACUÑAMIENTO ENTRE LAS ESFERAS BLOQUEANTES (57A, B) Y LAS PAREDES EN ANGULO (30) DE LA UNIDAD DE HERRAMIENTA (10), LAS PAREDES DE APERTURA (56) DEL MIEMBRO DE CAJA (39), SON EN ANGULO RESPECTO A UNA LINEA (R) QUE SE PROLONGA RADIALMENTE DESDE EL EJE DE LA BARRA DE BLOQUEO (A), PARA REDUCIR EL ANGULO ENTRE LA PARED DE APERTURA (56) Y LA PARED DE LA UNIDAD DE HERRAMIENTA (30). TALES ANGULAMIENTOS INCREMENTAN LA FUERZA DE LOS AJUSTES DE ACUÑAMIENTO Y DE BLOQUEO, ENTRE LAS ESFERAS BLOQUEANTES (57 A, B) Y LAS PAREDES EN ANGULO (30) DE LA UNIDAD DE HERRAMIENTA (10). EN LA REALIZACION PREFERIDA DE LA INVENCION, LAS PAREDES DE APERTURA (56) TIENEN UN ANGULO DE 15 A LA SUSODICHA LINEA RADIAL (R), INCREMENTANDO ASI LA FUERZA DE SUJECION DEL MECANISMO DE AMARRE (35) SOBRE UN 30 %.
