Abstract
Abstract A multiple spindle head usable with machine tools and particularly with the spindle of a numerically controlled machining center having automatic tool changing equipment wherein the head has a two-part body with one part of the body rotatably mounting a plurality of spindles which can be adjusted relative to each other for a preselected orientation and with a mounting stem rotatably mounted in the body and extending from the other body part to engage in the spindle of a machining center. Rotation of the spindle of the machining center rotates the mounting stem and the plurality of spindles. Locator means on the other body part rotatably orients the multiple spindle head to the machining center and holds the body against rotation during rotation of the plurality of spindles and means for varying the orientation of the plurality of spindles to the locator means including a rotatable mounting of one body part to the other about a central longitudinal axis and interfitting tapered rings one in each of said body parts for releasably locking the body parts against rotation.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
171 words
A multiple spindle head for use in numerical control machining centers comprising, an interlocked two-part body, one of said body parts rotatably mounting a plurality of spindles, a mounting stem rotatably mounted in said body and extending from the other body part for insertion into the spindle of said machining center, means within said body for transmitting rotation of the mounting stem to said plurality of spindles, locator means on the other body part engageable with the spindle head of the machining center to orient said body and hold said body against rotation, means for rotatably adjusting said body parts relative to each other about an axis lengthwise of said body to vary the orientation of the plurality of spindles to said locator means, said plurality of spindles being adjustably mounted on said one body part to vary their orientation one to the other, a template for locating each of said plurality of spindles in a selected position, and mounting posts for said template extending outwardly from said other body part.
Claim 2
Dependent Claim
171 words
A multiple spindle head for use in numerical control machining centers comprising, an interlocked two-part body, one of said body parts rotatably mounting a plurality of spindles, a mounting stem rotatably mounted in said body and extending from the other body part for insertion into the spindle of said machining center, means within said body for transmitting rotation of the mounting stem to said plurality of spindles, locator means on the other body part engageable with the spindle head of the machining center to orient said body and hold said body against rotation, means for rotatably adjusting said body parts relative to each other about an axis lengthwise of said body to vary the orientation of the plurality of spindles to said locator means, said plurality of spindles being adjustably mounted on said one body part to vary their orientation one to the other, a template for locating each of said plurality of spindles in a selected position, and mounting posts for said template extending outwardly from said other body part.
Claim 3
Dependent Claim
201 words
A multiple spindle head usable with machine tools and particularly with the spindle of a numerically controlled machining center comprising, a two-part body with a first body part mounting a plurality of spindles for rotation, means individually mounting each of said plurality of spindles to said first body part for variable positioning as required in a machining operation, a mounting stem rotatably mounted in said body and rotationally connected to said plurality of spindles and extending outwardly of the second body part for driving engagement with the spindle of the machining center, locator means on said second body part engageable with a stationary part of the machining center to rotatably orient the body and hold the body against rotation, and means for varying the orientation of said plurality of spindles to said locator means including a rotatable mounting of one body part to the other for rotation about a central longitudinal axis, and interfitting tapered rings one on each of said body parts for releasably locking said body parts against rotation, one of said interfitting rings being split and means for moving said split ring away from the other ring to permit rotatable adjustment of one body part to the other.
