Abstract
APARATO PARA CORREGIR PORCIONES EXTREMAS SUPERIORES DAÑADAS DE TUBOS GUIA DE UN CONJUNTO RECONSTITUIBLE DE COMBUSTIBLE.EL APARATO COMPRENDE UNA BASE (84) CON ABERTURAS DE COLOCACION DE HERRAMIENTA DISPUESTAS IGUAL QUE LOS TUBOS GUIA (14) DEL CONJUNTO DE COMBUSTIBLE (10); MEDIOS (92,70) PARA MONTAR LA BASE SOBRE LA ESTACION DE TRABAJO (68) DE MANERA QUE SUS ABERTURAS DE RECEPCION DE HERRAMIENTA ESTEN ALINEADAS CON LAS PORCIONES EXTREMAS DEL TUBO GUIA (44); Y DIFERENTES CLASES DE HERRAMIENTAS (94, 96, 98) MONTABLES SELECTIVAMENTE EN LAS ABERTURAS DE COLOCACION DE HERRAMIENTA PARA CORREGIR LOS DAÑOS DE LOS TUBOS GUIA. LAS HERRAMIENTAS INCLUYEN UN TUBO DE COMPRESION (94) PARA REFORMAR HACIA EL EXTERIOR PORCIONES CURVADAS DEL TUBO GUIA (44A); UNA HERRAMIENTA DE EXPANSION (96) PARA REFORMAR PORCIONES DEL TUBO GUIA CURVADAS HACIA EL INTERIOR (44B); Y UN CORTADOR DE TUBO (98) DE PRECISION PARA CORTAR SECCIONES DAÑADAS IRREPARABLEMENTE DE PORCIONES DEL TUBO GUIA (44C). CUALQUIER SECCION CORTADA ES SUSTITUIDA CON UN MANGUITO ADAPTADOR DEL INYECTOR SUPERIOR Y EL TUBO GUIA ACORTADO DEL CONJUNTO DE COMBUSTIBLE.
