Abstract
Disclosed is an assembly for holding a tool. The assembly may selectively reduce and/or eliminate vibrations received and felt by a user. Reducing vibrations may reduce or eliminate chatter at a working end of a tool.
Claims21
An assembly for holding a tool, comprising:
- an attachment base configured to be operably coupled to a motor housing assembly and having an attachment base receiving section;
- an attachment tube extending from a first terminal end to a second terminal end, the attachment tube having a connection region at the first terminal end that is received within the attachment base receiving section, the connection region having a first inner diameter extending along the attached base receiving section and a second inner diameter extending from an end of the attachment base receiving section, the first inner diameter larger than the second inner diameter;
- and
- a damping member positioned between the attachment base and at least a portion of the attachment tube;
- wherein the tool is configured to extend through the attachment base and the attachment tube and torque is transferred to the tool from a motor within the motor housing assembly;
- wherein the attachment tube is coupled to the attachment base at the first terminal end;
- wherein the second terminal end of the attachment tube extends from the attachment base;
- wherein the first and second inner diameters provide a vibration reduction feature.

An assembly for holding a tool, comprising:
- an attachment base having a motor housing connection configured to be operably coupled to a motor housing at an attachment connection and a tube connection bore;
- and
- an attachment tube extending from a first terminal end to a second terminal end, the attachment tube having a vibration reduction feature formed by at least a selected thickness of a wall of the attachment tube positioned between the first terminal end and the second terminal end;
- wherein the tool is configured to extend through the attachment base and the attachment tube and torque is transferred to the tool from a motor within the motor housing;
- wherein the attachment tube is coupled to the attachment base at an attachment base connection near the first terminal end;
- wherein the second terminal end of the attachment tube extends from the attachment base.
3 more elements
A method of forming an assembly for holding a tool, comprising:
- inserting a first length of a first terminal end of an attachment tube into a tube connection bore of an attachment base;
- fixing the attachment tube to the attachment base;
- wherein the attachment tube includes a vibration reduction feature between the first terminal end and a second terminal end of the attachment tube;
- wherein the vibration reduction feature includes forming a first internal diameter for the first length of the attachment tube that is inserted into the attachment base greater than a second internal diameter over a second length of the attachment tube that starts from an end of the attachment base.
