Abstract
A tool holder and spindle adapter includes a quick change section for securing into a power spindle, a body having an axial bore mounting a positive drive and a collet holder shank to receive a tool holder collet and tool, with the tool extending into operative engagement with the positive drive. A rotatable tool adjuster is mounted within the body upon a transverse axis and includes an eccentric cam device engageable with the positive drive for controlling longitudinal in and out adjustments of the tool.
Claims7
A tool holder and spindle adapter comprising a quick change section having a first longitudinal axis adapted for axial mounting and securing within a power rotated spindle;
- a body on said quick change section having an axial bore;
- a positive drive positioned within said bore for selected longitudinal adjustments in said body;
- there being a transverse slot across the top of said positive drive;
- a collet holder shank extending from said body arranged upon said axis;
- a collet axially mounting a cutting tool extending into said collet holder shank and adjustably secured thereto for anchoring said cutting tool in said shank;
- the inner end of said cutting tool being in operative engagement with said positive drive;
- there being a radial bore in said body extending to said axial bore;
- a tool adjuster nested and retained within said radial bore for rotation on a second axis at about right angles to said first axis;
- a cam pin mounted within said tool adjuster upon a third axis eccentric to, spaced from and parallel to said second axis, with one end of said pin projecting from said adjuster and into said transverse slot operatively engaging said positive drive;
- and
- selective adjustment of said tool adjuster upon release of said collet effecting corresponding longitudinal adjustments of said positive drive within said body, and corresponding longitudinal adjustments of said tool.

- the inner end of said cutting tool being in operative engagement with said positive drive;
- a tool adjuster nested and retained within said body for rotation on a second axis at about right angles to said first axis;
- an eccentric cam means on said tool adjuster operatively engaging said positive drive, whereby with said collet released, selective adjustment of said tool adjuster effects corresponding longitudinal adjustments of said positive drive within said body, and corresponding longitudinal adjustments of said tool;
- and
- further comprising said positive drive having a wedge shaped aperture at one end with said tool at one end nested within said aperture.
