Abstract
A tool holder adapted to be mounted on a lathe turret is of rigid, one-piece construction and removably secures any one of a wide range of interchangeable drills of different diameters. The tools are secured at a centerline located at an exact predetermined distance, e.g. 0.375 inch, above the bottom surface of the holder so as to exactly locate the centerline of the tool respective the top surface of the turret. The distal end of the tool holder is spaced fractionally above the base plate of the lathe turret, providing for spring-loading of the tool.
Claims8
A tool holder adapted for releasable mounting on a lathe turret including mean for horizontally supporting an elongated tool over a part of it length, comprising:
- a one piece housing formed with (a) a first plane bottom surface for flat connection to said lathe turret, (b) an interior wall surface defining a passage including, in cross section, a V-shaped portion at one end of said passage of serving as a seat for said tool and including an angle of 90.degree. with a horizontally diposed bi-sector at a predetermined distance from said first bottom surface, (c) a distal bottom surface separated from said first surface by said passage and dimensioned to be fractionally spaced from the plane of said lathe turret to enable spring-loading of said tool supported in said housing, and (d) a vertical bore from said first plane bottom surface entirely through said housing for insertion of a stud therethrough for retention of the tool holder on said lathe turret;
- and
- means for securing said tool in said V-shaped portion whereby the centerline of said tool is disposed coincident with said horizontal bi-sector.
A tool holder adapted for releasable mounting on a lathe turret including means for horizontally supporting an elongated tool over a part of its length, comprising:
- a housing formed with an interior wall surface defining a passage including, in cross section, a V-shaped portion at one end of said passage serving as a seat for said tool and including an angle of 90.degree. with a horizontally disposed bi-sector at a predetermined distance from a bottom housing surface, a portion of said interior wall surface being distal from, and opposite to, said bi-sector and bored to receive a plurality of bolts therethrough for securing said tool in said V-shaped portion whereby the centerline of said tool is disposed coincident which said horizontal bi-sector, another portion of said interior wall surface extending from said distal wall surface around said passageway, a portion of said housing slanting exteriorly thereat, said slanting housing portion being thinner than adjacent portions whereby to permit spring loading of said tool.
