Abstract
An interchangeable tool mounting device, which is particularly adapted for retaining turret lathe center drills in a desired position, includes an elongated body portion having at least one center drill receiving passage extending inwardly from at least one end thereof. The passage is adapted to receive a standard size center drill and includes a cylindrical portion and a tapered inner end portion of frusto-conical shape. Abutment surfaces or pins are provided in the tool receiving passage, and flutes formed on the center drill abut against the abutting surfaces or pins to position the center drill relative to the mounting device.
Claims17
In a tool holder for a center drill having a circular shank portion of a given diameter, a smaller diameter tip portion coaxial with said shank portion, a tapered portion between said shank and tip portions, and flute means extending from said tip portion through said tapered portion and into said shank portion, said flute means including recess means having terminal end means interconnecting the circular outer surface of said shank portion, and said tool holder comprising a body member having an end and a tool receiving passage extending thereinto from said end, the improvement comprising:
- said passage having an axially outer cylindrical portion of a diameter to receive said shank portion and an axially inner portion to receive said tip portion, said inner portion of said passage having a transverse dimension smaller than said given diameter of said shank portion of said center drill, said passage including a tapered section between said outer and inner portion of said passage, said tapered section being engaged by said tapered portion of said center drill to axially position said center drill in said passage, and abutment means in said passage to engage said flute means against rotation of said center drill in said passage, said abutment means including surface means located radially inwardly with respect to the surface of said axially outer cylindrical portion of said passage, and said abutment means being axially located in said passage to intersect both said outer cylindrical portion and said tapered section of said passage.
In a tool holder for a center drill having a circular shank portion of a given diameter, a smaller diameter tip portion coaxial with said shank portion, a tapered portion between said shank and tip portions, and flute means extending from said tip portion through said tapered portion and into said shank portion, said flute means including recess means having terminal end means intersecting the circular outer surface of said shank portion, and said tool holder comprising a body member having an end and a tool receiving passage extending thereinto from said end, the improvement comprising:
- said passage having an axially outer cylindrical portion of a diameter to receive said shank portion and an axially inner portion to receive said tip portion, said inner portion of said passage having a transverse dimension smaller than said given diameter of said shank portion of said center drill, said passage including shoulder means engaged by said tapered portion of said center drill to axially position said center drill in said passage, and abutment means in said passage to engage said flute means against rotation of said center drill in said passage, said abutment means including surface means located radially inwardly with respect to the surface of said axially outer cylindrical portion of said passage, said abutment means being axially located in said passage forwardly of said terminal end means of said recess means when said shoulder means is engaged by said tapered portion, said shoulder means being a tapered section of said tool receiving passage between said outer and inner passage portions, and said abutment means comprising means defining opening means extending through said body member into said passage and intersecting both said outer cylindrical portion and said tapered section of said passage to define said surface means of said abutment means.
In a tool holder for a center drill having a circular shank portion of a given diameter, a smaller diameter tip portion coaxial with said shank portion, a tapered portion between said shank and tip portion, and flute means extending from said tip portion through said tapered portion and into said shank portion, said flute means including recess means having terminal end means intersecting the circular outer surface of said shank portion, and said tool holder comprising a body member having an end and a tool receiving passage extending thereinto from said end, the improvement comprising:
- said passage having an axially outer cylindrical portion of a diameter to receive said shank portion and an axially inner cylindrical portion to receive said tip portion, said inner portion being of a diameter smaller than said given diameter of said shank portion of said center drill, said passage further including a tapered section between said outer and inner portions of said passage, said tapered section being engaged by said tapered portion of said center drill to axially position said center drill in said passage, means defining an opening extending into said body member in a direction transverse to the axis of said passage, said opening having an inner end intersecting both said outer portion and said tapered section of said passage to provide an abutment surface in said passage to engage said flute means against rotation of said center drill in said passage when said tapered section of said passage is engaged by said tapered portion of said center drill.
