Abstract

SE PRESENTA UNA MAQUINA, COMO POR EJ. UNA EXCAVADORA, QUE COMPRENDE UN ACOPLAMIENTO (18) PARA CONECTAR HERRAMIENTAS DE FORMA INTERCAMBIABLE (19) A UN BRAZO ARTICULADO (13). EL ACOPLAMIENTO INCLUYE UN PRIMER MIEMBRO DE ACOPLAMIENTO (16) SOPORTADO SOBRE EL BRAZO (13), UN SEGUNDO MIEMBRO DE ACOPLAMIENTO (17) PROVISTO SOBRE CADA UNA DE LAS HERRAMIENTAS (19), UN MIEMBRO DE SUJECCION (38) SITUADO EN EL PRIMER MIEMBRO DE ACOPLAMIENTO Y MOVIL ENTRE POSICIONES DE SUJECCION Y DE LIBERACION, UN MUELLE (39) DISPUESTO ENTRE EL PRIMER MIEMBRO DE ACOPLAMIENTO Y EL MIEMBRO DE SUJECCION PARA SUJETAR EL MIEMBRO DE SUJECCION EN SU POSICION DE SUJECCION, Y UN MECANISMO LIBERADOR QUE FUNCIONA HIDRAULICAMENTE (34) QUE ESTA SITUADO EN EL PRIMER MIEMBRO DE ACOPLAMIENTO PARA MOVER EL MIEMBRO DE SUJECCION A SU POSICION DE LIBERACION EN OPOSICION A LA FUERZA DEL MUELLE (39). UN FLUIDO HIDRAULICO A UN NIVEL DE PRESION PREDETERMINADO SE APLICA A TRAVES DE UNA PRIMERA VALVULA NO RETORNABLE (59) PARA LIBERAR EL MIEMBRO DE SUJECCION Y PERMITIR EL DESENGANCHE DE LA HERRAMIENTA (19) Y EL ENGANCHE DE OTRA HERRAMIENTA (19); EL FLUIDO HIDRAULICO PRESURIZADO SE HACE SALIR A TRAVES DE UNA SEGUNDA VALVULA DE NO RETORNO PARA DEVOLVER EL MIEMBRO DE SUJECCION A SU POSICION DE SUJECCION, MEDIANTE LO CUAL PUEDE RETENER UNA HERRAMIENTA NUEVAMENTE MONTADA (19) BAJO LA PRESION DEL MUELLE (39).
