US 5,873,682 A · Pivoting tool holder

Abstract

The present invention is a tool holder for supporting a cutting insert during a material-removal process. The tool holder comprises a body having a channel formed therein for receiving a finger that extends from a head. The finger is secured within the channel by an assembly screw that permits the head to move between a retracted position and an extended position relative to the body. When the head is in its extended position, the head is permitted to pivot relative to the body; however, when the head is in its retracted position a pair of shoulders on the body engage a pair of notches on the head, preventing the head from pivoting. A locking screw is also provided that locks the head to the body. The locking screw is designed so that as the locking screw is tightened, the head is urged against the body, thus providing a positive known position for the insert each time the head is moved. In an alternative embodiment, the body and head are provided with a first and second flange, respectively, that engage each other and limit the pivotal movement of the head between a first position and a second position, 180.degree. away from the first position.

Dependent claims

A tool holder for supporting a cutting insert, said tool holder comprising:

a body having a channel formed therein;
a head having a finger dimensioned to be rotatably received within said channel, said head having a retracted position and an extended position within said channel with respect to said body;
means for preventing pivoting of said head with respect to said body when said head is in said retracted position but not preventing pivoting of said head with respect to said body when said head is in said extended position;
means carried by said body for restricting movement of said head axially with respect to said body between said retracted and said extended positions but not restricting pivoting of said head;
and
means for locking said head in said retracted position.

A tool holder for supporting a cutting insert, said tool holder comprising:

a body having a channel and a pair of threaded apertures formed therein, said pair of threaded apertures extending through said body to communicate with said channel;
a head having a finger dimensioned to be rotatably received within said channel, said head having a retracted position and an extended position in said channel, said finger including a reduced diameter portion;
means for preventing pivoting of said head with respect to said body when said head is in said retracted position but not preventing pivoting of said head with respect to said body when said head is in said extended position;
an assembly screw dimensioned to be threaded into a first aperture of said pair of apertures and engage said reduced diameter portion of said finger so that, when said finger is received in said channel and said assembly screw is threaded into said first aperture to engage said reduced diameter portion of said finger, said head is movable between said extended position and said retracted position but not removable from said body;
and
a locking screw dimensioned to be threaded into a second aperture of said pair of apertures to engage said finger so that, when said finger is received within said channel and said locking screw is threaded into said second aperture, said head is locked in said retracted position.
