Abstract

UNA MAQUINA DE PERFORAR AGUJEROS EN UNA ROCA TIENE UN ALOJAMIENTO TUBULAR (12) CON UN MARTILLO DE PISTON (24) QUE ESTA GUIADO SOLO EN SUS EXTREMOS. SU PARTE DELANTERA ES GUIADA POR UN MANGUITO GUIA (18) QUE SE APOYA CONTRA UN SALIENTE (13) EN EL ALOJAMIENTO Y SU PARTE TRASERA ES GUIADA POR UN ALOJAMIENTO DE VALVULA (20). EL MANGUITO GUIA (18), EL ALOJAMIENTO DE VALVULA (20) Y UN TUBO DE DISTANCIA (19) ENTRE LOS MISMOS SE ENCUENTRAN AFIANZADOS CONTRA EL SALIENTE (13) POR MEDIO DE UN CABEZAL POSTERIOR (22) ENROSCADO AL ALOJAMIENTO DE LA MAQUINA (12). EL TUBO DE DISTANCIA (19) ESTA ADAPTADO PARA SER COMPRIMIDO AXIALMENTE AL MENOS 0,3 PRO MILLAR DE SU LONGITUD Y PREFERIBLEMENTE ENTRE 0,8 Y 3 PRO MILLAR DE SU LONGITUD CUANDO EL CABEZAL POSTERIOR ESTA ENROSCADO EN POSICION. ESTA DISPOSICION PROPORCIONA UNA MAQUINA ROBUSTA Y EL ENSAMBLAJE Y DESENSAMBLAJE DE LA MAQUINA SERA FACIL. LAS TOLERANCIAS EN LONGITUD NO SERAN CRITICAS LO QUE HACE MENOS CRITICO EL FRESADO DE LAS DIFERENTES PIEZAS DE LA MAQUINA.A HOLE DRILLING MACHINE ON A ROCK HAS A TUBULAR HOUSING (12) WITH A PISTON HAMMER (24) THAT IS GUIDED ONLY IN ITS EXTREME. ITS FRONT PART IS GUIDED BY A GUIDE HOSE (18) THAT SUPPORTS AGAINST A PROJECT (13) IN THE ACCOMMODATION AND ITS REAR PART IS GUIDED BY AN ACCOMMODATION OF VALVE (20). THE GUIDE HOSE (18), THE VALVE HOUSING (20) AND A DISTANCE TUBE (19) BETWEEN THE SAME ARE FOUNDED AGAINST THE OUTPUT (13) THROUGH A REAR HEAD (22) THREADED TO THE HOUSING OF THE MACHINE ( 12). THE DISTANCE TUBE (19) IS ADAPTED TO BE COMPRESSED AXIALALLY AT LEAST 0.3 MILES OF THEIR LENGTH AND PREFERABLY BETWEEN 0.8 AND 3 MILES OF THEIR LENGTH WHEN THE REAR HEAD IS THREADED IN POSITION. THIS PROVISION PROVIDES A ROBUST MACHINE AND THE ASSEMBLY AND DISASSEMBLY OF THE MACHINE WILL BE EASY. THE TOLERANCES IN LENGTH WILL NOT BE CRITICAL WHAT MAKES THE MILLING OF THE DIFFERENT PARTS OF THE MACHINE LESS CRITICAL.
