Abstract
A drilling machine with an automatic tool changer (A.T.C.) including a driving motor which drives a spindle head to traverse, upwards and downwards and a tool magazine which is rotatably supported by the spindle head and has a plurality of tools, wherein when one of the tools is to be interchanged with another of the tools, said tool magazine is rotated at predetermined angles by the driving motor by means of the spindle head and a link mechanism.
Claims7
A machine provided with an automatic tool changer, comprising:
- a motor,
- a spindle head, means operatively connecting said motor and said spindle head to move said spindle head along an axis,
- a spindle rotatably held by said spindle head,
- a bar having one end thereof slidably supported by said spindle head,
- a tool magazine rotatably supported by the other end of said bar,
- a plurality of tool arbors rotatably held by said tool magazine and arranged such that as said tool magazine is rotated said tool arbors are sequentially aligned with said axis of movement of said spindle head, and means adapting said tool arbors to be engaged by said spindle to rotate said tool arbors and to be disengaged from said spindle,
- spring means urging said bar and said tool magazine attached thereto to a position wherein said tool arbors engage said spindle in driving relationship,
- a rod, means universally connecting one end of said rod to said tool magazine, and means universally connecting the other end of said rod to said spindle head such that as said spindle head is driven by said motor along said axis said rod causes said tool magazine to be rotated with respect to said bar.
