Abstract
Perfeccionamientos introducidos en un mandril de sujeción accionado por fuerza, con mordazas de sujeción conducidas en sentido radial en un cuerpo de mandril, y que por medio de un dentado recto pueden ser accionadas por sendas mordazas de impulsión, que son movibles radialmente dentro del cuerpo del mandril y que, a su vez son impulsadas por un émbolo del mandril, movible axialmente en el cuerpo del mandril, que acciona conjuntamente todas las mordazas de impulsión, caracterizados porque, independientemente de la mordaza de sujeción correspondiente, cada mordaza de impulsión está conducida directamente en el cuerpo del mandril en sentido radial y tangencial, así como también determinadas en su posición en dirección axial; porque con ello viene dado un aseguramiento indirecto de la unión en arrastre de forma, original por los dentados rectos, entre las mordazas de sujeción y las mordazas de impulsión, y porque el émbolo del mandril, conducido directamente en el cuerpo del mismo, es trasladable hasta más allá de la carrera de trabajo, a una posición en la que no engrana con las mordazas de impulsión.
