Abstract

LA INVENCION SE REFIERE A UN EQUIPO DE FIJACION DE RECORRIDO CORTO PARA FIJAR DE FORMA LIBERABLE UNA UNIDAD DE HERRAMIENTA EN UN SOPORTE. EL EQUIPO DISPONE DE UN ELEMENTO DE RECEPTACULO CON ORIFICIOS PARA PERMITIR EL PASO DE ELEMENTOS DE BLOQUEO ESFERICOS ASI COMO UNA VARILLA DE BLOQUEO QUE PUEDE DESPLAZARSE CON MOVIMIENTO DE VAIVEN CON UN RECORRIDO A LO LARGO DE UN EJE Y QUE PRESENTA SECCIONES DE EXCENTRICA PARA HACER PASAR LOS ELEMENTOS DE BLOQUEO ESFERICOS A TRAVES DE LOS ORIFICIOS DEL RECEPTACULO PARA SU ACOPLAMIENTO A LA UNIDAD DE HERRAMIENTA. EN EL EQUIPO DE FIJACION LOS ORIFICIOS DEL ELEMENTO DE RECEPTACULO SON ALARGADOS EN EL SENTIDO DEL EJE DE RECORRIDO, PERMITIENDO ASI EL MOVIMIENTO AXIAL DE LOS ELEMENTOS DE BLOQUEO ESFERICOS A LO LARGO DE LAS PORCIONES DE EXCENTRICA DE LA VARILLA DE BLOQUEO ASI COMO EL MOVIMIENTO RADIAL, DE FORMA QUE PUEDA CONSEGUIRSE UN ACOPLAMIENTO DE BLOQUEO CON UN MOVIMIENTO DE LA VARILLA DE BLOQUEO CON UN RECORRIDO AXIAL MAS CORTO. LAS PAREDES DE LOS ORIFICIOS TAMBIEN PUEDEN ESTAR INCLINADAS PARA PERMITIR UN MOVIMIENTO AXIAL AUN MAYOR DE LOS ELEMENTOS DE BLOQUEO, REDUCIENDO ASI AUN MAS EL RECORRIDO DE LA VARILLA DE BLOQUEO Y AUMENTANDO ASIMISMO LA FUERZA DE AGARRE APLICADA POR EL EQUIPO DE FIJACION SOBRE LA UNIDAD DE HERRAMIENTA. ESTE RECORRIDO MAS CORTO DE LA VARILLA DE BLOQUEO REDUCE, A SU VEZ, FAVORABLEMENTE LA ENVOLTURA DE LA HERRAMIENTA Y AUMENTA TANTO LA RIGIDEZ COMO LA DURACION DEL GRUPO DE MUELLES QUE ACTUA SOBRE LA VARILLA DE BLOQUEO. LA INCLINACION DE LAS PAREDES DE LOS ORIFICIOS AUMENTA ASIMISMO LA FUERZA DE ACOPLAMIENTO ENTRE LOS ELEMENTOS DE BLOQUEO Y LA UNIDAD DE HERRAMIENTA.
