Abstract
A boring bar whose body has an inclined end surface on one free end thereof against which an elongate cutting member is positioned. The inclined end surface has a recess extending inwardly therefrom in which a yoke member is positioned, the yoke member having a portion extending outwardly beyond the inclined end surface and perpendicular thereto and surroundingly engaging the cutting member, and a screw or other suitable securing element cooperates with the yoke member for applying an inward force thereto in a direction perpendicular to the inclined end surface for clampingly securing the cutting member firmly against the inclined end surface of the body.
Claims11
A boring bar comprising an elongate body having a free end provided with an end surface thereon inclined at an acute angle transversely of the longitudinal axis of said body, an elongate cutting member positioned against said inclined end surface, said inclined end surface having a recess extending inwardly therefrom, a yoke member positioned in said recess and having a portion extending outwardly beyond said inclined end surface and perpendicular thereto and surroundingly engaging said cutting member, said yoke member also having an inner portion extending inwardly beyond said recess and perpendicular to said inclined end surface, and securing means cooperating with said inner portion of said yoke member for applying an inward force thereto in a direction perpendicular to said inclined end surface of said body for clampingly securing said cutting member firmly against said inclined end surface.
A boring bar comprising an elongate body having a free end provided with an end surface thereon inclined at an acute angle transversely of the longitudinal axis of said body, an elongate cutting member positioned against said inclined end surface, said inclined end surface having a recess therein and a passage communicating with said recess and extending inwardly therefrom substantially perpendicular to said inclined end surface, a yoke member positioned in said recess and having a portion extending outwardly beyond said inclined end surface and perpendicular thereto and engaging at least the outer surface of said elongate cutting member, said yoke member also having a shank portion thereon extending perpendicular to said inclined end surface and inwardly into said passage, and securing means cooperating with said shank portion for applying an inward force thereon in a direction perpendicular to said inclined end surface of said body for clampingly securing said cutting member firmly against said inclined end surface of said body.
A boring bar comprising an elongate body having a free end with an acutely inclined end surface extending transversely of the longitudinal axis of said body, an elongate cutting member positioned against said inclined end surface, said inclined end surface having a recess therein and a passage communicating with and being of lesser cross-sectional area than said recess and extending substantially perpendicular to said inclined end surface, a yoke member having a main portion of out of round cross-sectional configuration and engaging opposite portions of said body defining said recess, said main portion of said yoke member surroundingly engaging said cutting member, said yoke member also having a shank portion extending perpendicular to said inclined end surface and inwardly from said main portion into said passage, and threaded fastening means positioned in that end of said passage remote from said yoke member main portion and threadedly engaging said shank portion for applying an inward force to said yoke member in a direction perpendicular to said inclined end surface for clampingly securing said cutting member firmly against said inclined end surface of said body.
