Abstract
A disk magazine particularly useful as a tool holder for a universal drilling and milling machine comprises a disk having a plurality of tool holders disposed at fixed intervals on the outer perimeter and a drive means for rotating the disk in steps corresponding to the spacing between the tool holders. The disk comprises a connected pair of spaced apart flat plates. In a preferred embodiment, at least one of the plates is an annular plate having recessed regions on its inner periphery and the drive means comprises a Geneva drive mechanism for engaging the recessed regions. This disk magazine can be conveniently mounted on a universal drilling and milling machine with the disk horizontal above the headstock.
Claims16
A magazine tool holder for machine tools of the milling and drilling type, said machine tool having a headstock, the tools used by said machine tool being formed with a peripheral collar, said tool holder comprising:
- a low-mass disk mounted horizontally above the headstock and comprising:
- a first thin flat plate formed with a plurality of angularly spaced radial tool receiving recesses in the periphery thereof;
- a second thin flat plate formed with a like plurality of angularly spaced radial tool receiving recesses in the periphery thereof;
- means for securing said first and second plates together in spaced confronting relationship with said respective tool receiving recesses in registration, the space between said plates being adapted to radially receive the collar of the tools which said tool holder is adapted to engage;
- said second plate being annular in shape and being formed with Geneva drive means as one portion of a Geneva drive mechanism;
- means mounted to one of said plates adapted to engage and radially releasably retain a tool in each of said tool receiving recesses, the tool receiving recesses of each said plate being adapted to provide a bearing surface for the shaft of the tool adjacent the collar for stability of the tool in said magazine tool holder, said bearing surfaces having substantially equal stabilizing effect upon the tool;
- a central bearing rotatably mounted to said machine tool;
- means for mounting said disk to said central bearing for rotation therewith;
- a Geneva drive gear engaging said Geneva drive means on said second plate;
- and
- a motor coupled to said Geneva drive gear for selective rotation thereof and step rotation of said disk, said Geneva drive mechanism being radially spaced from the axis of said central bearing and adjacent to the periphery of said disk.
