Abstract
Abstract An automatic tooling machine includes a spindle carrier having a spindle for supporting a machining tool. The spindle carrier includes a tool drum mounting device for rotatably supporting a tool drum having plural machining tools thereon. A device is provided for transferring a selected machining tool between the tool drum supported on the tool drum mounting device and the spindle. A drum storage rack is fixedly positioned separate from the spindle carrier and extends in a longitudinal direction. The rack includes a plurality of drum support members for storing a plurality of tool drums. A carriage track is integral with the spindle carrier. A device is provided for selectively moving the spindle carrier to a position such that the carriage track is positioned adjacent and aligned with a selected of the drum support members. A carriage is provided for moving the tool drum of the selected drum support member along the carriage track between the tool drum mounting device and the selected drum support member. A servo-motor and worm gear arrangement is provided for rotating the tool drum on the tool drum mounting device.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
231 words
In an automatic tooling machine of the type including a spindle carrier having a spindle for supporting a machining tool, said spindle carrier including tool drum mounting means for rotatably supporting a tool drum with plural machining tools thereon, means for transferring a selected machining tool between said tool drum supported on said tool drum mounting means and said spindle, and means for selectively moving said spindle in X, Y and Z directions to position said selected machining tool in a desired operating position, the improvement comprising: a fixedly positioned drum storage rack separate from said spindle carrier and extending in a longitudinal direction, said rack including a plurality of drum support members for storing a plurality of said tool drums; said spindle carrier having integral therewith a carriage track; means for selectively moving said spindle carrier to a position such that said carriage track is positioned adjacent and aligned with a selected said drum support member; means, mounted on said spindle carrier, for moving the said tool drum associated with said selected drum support member along said carriage track in a selected direction between said selected drum support member and said tool drum mounting means; and means, mounted on said spindle carrier, for rotating said tool drum on said tool drum mounting means and for thereby selectively rotatively aligning said tool drum with respect to said tool drum mounting means.
Claim 2
Dependent Claim
231 words
In an automatic tooling machine of the type including a spindle carrier having a spindle for supporting a machining tool, said spindle carrier including tool drum mounting means for rotatably supporting a tool drum with plural machining tools thereon, means for transferring a selected machining tool between said tool drum supported on said tool drum mounting means and said spindle, and means for selectively moving said spindle in X, Y and Z directions to position said selected machining tool in a desired operating position, the improvement comprising: a fixedly positioned drum storage rack separate from said spindle carrier and extending in a longitudinal direction, said rack including a plurality of drum support members for storing a plurality of said tool drums; said spindle carrier having integral therewith a carriage track; means for selectively moving said spindle carrier to a position such that said carriage track is positioned adjacent and aligned with a selected said drum support member; means, mounted on said spindle carrier, for moving the said tool drum associated with said selected drum support member along said carriage track in a selected direction between said selected drum support member and said tool drum mounting means; and means, mounted on said spindle carrier, for rotating said tool drum on said tool drum mounting means and for thereby selectively rotatively aligning said tool drum with respect to said tool drum mounting means.
Claim 3
Dependent Claim
34 words
The improvement claimed in claim 1, wherein each said drum support member includes pin means for selective engagement with the respective said tool drum for securing said tool drum to said drum support member.
Claim 4
Dependent Claim
24 words
The improvement claimed in claim 1, wherein each said drum support member has a transverse cross-sectional configuration identical to that of said carriage track.
Claim 5
Dependent Claim
35 words
The improvement claimed in claim 1, further comprising means, positioned on each said drum support member and on said carriage track, to detect the alignment of said carriage track with said selected drum support member.
Claim 6
Dependent Claim
75 words
The improvement claimed in claim 1, wherein said carriage track comprises a base track member fixed to said spindle carrier, and an extension track member fixed to said spindle carrier and extending therefrom toward said drum storage rack, said extension track member and said base track member being aligned and having identical transverse cross-sectional configurations, and said extension track member and said base track member have aligned side tracks for guiding therealong said tool drum.
Claim 7
Dependent Claim
130 words
The improvement claimed in claim 5, wherein said extension track member and said base track member have an aligned upper track, each said drum support member has side tracks adapted to be aligned with said side tracks of said extension track member and an upper track adapted to be aligned with said upper track of said extension track member, and wherein said tool drum moving means comprises a carriage mounted for sliding movement along said upper tracks of said base track member, extension track member and drum support member, means for reciprocatingly moving said carriage along said upper tracks, and means on said carriage for selectively grasping said tool drum and for thereby moving said tool drum along said side tracks during movement of said carriage along said upper tracks.
Claim 8
Dependent Claim
51 words
