Abstract

Mandril portabrocas con un cuerpo de mandril para conectarse al husillo de perforación de una máquina perforadora y con mordazas de sujeción para la broca, que pueden ser ajustadas por desplazamiento centradamente con relación al eje del mandril por medio de un aro de ajuste guiado en el cuerpo de mandril de modo capaz de girar e incapaz de desplazarse axialmente, caracterizado porque el aro de ajuste forma un disco anular coaxial con relación al cuerpo de mandril, situado delante de su superficie frontal por el lado de la broca y provisto de un orificio para la broca, porque las mordazas de sujeción están guiadas en rendijas radiales de este disco anular, abiertas en dirección al orificio para la broca, y porque el cuerpo de mandril por su lado frontal orientado hacia el disco anular, está provisto de una rosca plana (rosca en espiral) cuyos hilos de rosca (en espiral) están en engrane con correspondientes segmentos de hilo de rosca planos (en espiral) por el lado de las mordazas de sujeción que está orientado hacia el cuerpo de mandril.
