Abstract
A retainer for a tool comprises an annular body, a plurality of protruding bosses, and a slot formed through the body in an axial direction. The annular body defines a central opening adapted to receive a tool therein in the axial direction and includes a first end having a first external diameter, and a second end having a second external diameter. The plurality of protruding bosses extend into the opening from an internal side of the body defining the central opening. In a resting state of the body, the first external diameter and the second external diameter are distinct from one another. The body is elastically deformable into a compressed state wherein the first external diameter and the second external diameter are equal.
Claims19
A retainer for a tool, comprising:
- an annular body defining a central opening adapted to receive a tool therein in an axial direction and including a first end having a first external diameter, and a second end having a second external diameter;
- a plurality of protruding bosses extending into the opening from an internal side of the body defining the central opening;
- and
- a slot formed through the body and extending in the axial direction between the first end and the second end, wherein:
- in a resting state of the body, the first external diameter and the second external diameter are distinct from one another;
- the body is elastically deformable into a compressed state wherein the first external diameter and the second external diameter are equal;
- in the resting state, a width of the slot tapers between the first end of the body and the second end of the body in the axial direction;
- and
- in the compressed state of the body, the width of the slot is generally constant between the first and second ends of the body.
A tool subassembly, comprising:
- a tool retainer, including:
- an annular body defining a central opening adapted to receive a tool therein in an axial direction and including a first end having a first external diameter, and a second end having a second external diameter;
- a plurality of protruding bosses extending into the central opening from an internal side of the body defining the central opening;
- and
- a slot formed through the body and extending in the axial insertion direction between the first end and the second end, wherein:
- in a resting state of the body, the first external diameter and the second external diameter are distinct from one another;
- the body is elastically deformable into a compressed state wherein the first external diameter and the second external diameter are equal;
- in the resting state, a width of the slot tapers between the first end of the body and the second end of the body in the axial direction;
- and
- in the compressed state of the body, the width of the slot is generally constant between the first and second ends of the body;
- and
- a compression element defining an opening adapted to receive the tool retainer, the opening having an internal dimension less than the first external diameter of the annular body, the compression element adapted to elastically deform the first end of the retainer in a radially inward direction as the compression element is translate over the retainer from the second end toward the first end.
A tool assembly, comprising:
- a tool holder defining a bore extending therein;
- a tool having a shank;
- a tool retainer fitted over the shank, including:
- an annular body defining a central opening receiving the tool therein in an axial direction and including a first end having a first external diameter, and a second end having a second external diameter;
- a slot formed through the body and extending in the axial direction between the first end and the second end, wherein:
- in a resting state of the body, the first external diameter and the second external diameter are distinct from one another;
- the body is elastically deformable into a compressed state wherein the first external diameter and the second external diameter are equal;
- in the resting state, a width of the slot tapers between the first end of the body and the second end of the body in the axial direction;
- and
- in the compressed state of the body, the width of the slot is generally constant between the first and second ends o the body;
- and
- a compression element defining an opening adapted to receive the tool retainer, the opening having an internal dimension less than the first external diameter of the annular body.
