Setting gage for multiple head tool holder

Claim 2

A setting gage for a tool holder having multiple cutting tool heads located therein, said setting gage comprising a gage means; a gage positioning means for positioning said gage means along an axis extending in a first direction; a spindle shaft for retaining and positioning the multiple head tool holder, the longitudinal axis of said spindle shaft extending in a second direction perpendicular to said first direction; a visual readout means interrelated with said gage positioning means so as to yield a visual indication of the position of said gage means relative to said spindle shaft axis, said visual indication being representative of the diameter of a tube of twice the distance between said gage means and said spindle shaft axis; and a spindle reciprocating means for controllably orienting said multiple head tool holder with respect to said axis extending in said first direction whereby said gage means acts as a guide to properly align the cutting tools of said multiple head tool holder.

Claim 3

The apparatus of claim 1 wherein said gage means comprises a template block having at least one face thereof shaped to the configuration of a standard finished tube end.

Claim 4

The apparatus of claim 1 wherein said spindle shaft includes a bore in one end thereof for retaining said tool holder while permitting forced relative movement therebetween, aNd said spindle reciprocating means comprises a first drive mechanism for course adjustment of said spindle shaft with respect to said axis extending in said first direction, a second drive mechanism for fine adjustment of said spindle shaft with respect to said axis extending in said first direction and a selective locking mechanism to lock the location of said spindle shaft when its desired location relative to said axis extending in said first direction is achieved.

Claim 5

A setting gage for a tool holder having multiple cutting tool heads located therein, said setting gage comprising: a housing, said housing having a base, a first portion upstanding from said base and a second portion upstanding from said base, said first upstanding portion being spaced from said second upstanding portion; an adjusting arm passing through said first upstanding portion and supported therein for limited vertical movement; a gage means comprising a template block having at least one face thereof shaped to the configuration of a standard finished tube end, said gage means connected to said adjusting arm for vertical movement therewith; a motor fixed to said first upstanding portion and operably associated with said adjusting arm for controlling the vertical movement thereof with respect to a fixed reference; a spindle shaft passing through said second upstanding portion opposite said adjusting arm, said spindle shaft supported within said second upstanding portion for reciprocation therethrough along its longitudinal axis, said axis forming said aforementioned fixed reference; a bore in the forward end of said spindle shaft adapted to releasably retain the multiple head tool holder; a means for reciprocating said spindle shaft along its longitudinal axis to selectively move the forward end thereof adjacent said gage means; and a visual readout means interrelated with said motor and said adjusting arm so as to yield a visual indication of the position of said gage means connected to said adjusting arm relative to said fixed reference.

Claim 6

A setting gage for a tool holder having multiple cutting tool heads located therein, said setting gage comprising: a housing, said housing having a base, a first portion upstanding from said base and a second portion upstanding from said base, said first upstanding portion being spaced from said second upstanding portion; an adjusting arm passing through said first upstanding portion and supported therein for limited vertical movement; a gage means comprising a template block having at least one face thereof shaped to the configuration of a standard finished tube end, said gage means connected to said adjusting arm for vertical movement therewith; a motor fixed to said first upstanding portion and operably associated with said adjusting arm for controlling the vertical movement thereof with respect to a fixed reference; a spindle shaft passing through said second upstanding portion opposite said adjusting arm, said spindle shaft supported within said second upstanding portion for reciprocation therethrough along its longitudinal axis, said axis forming said aforementioned fixed reference; a bore in the forward end of said spindle shaft adapted to releasably retain the multiple head tool holder; a means for reciprocating said spindle shaft along its longitudinal axis to selectively move the forward end thereof adjacent said gage means; and a visual readout means interrelated with said motor and said adjusting arm so as to yield a visual indication of the position of said gage means connected to said adjusting arm relative to said fixed reference.

Claim 7

The apparatus of claim 4 wherein said means for reciprocating said spindle shaft includes a first drive mechanism for coarse adjustment of said spindle shaft with respect to said gage means, a second drive mechanism for fine adjustment of said spindle shaft with respect to said gage means and a selective locking mechanism to lock the location of said spindle shaft when its desired location relative to said gage means is achieved.
