Abstract
A pneumatically powered spindle wrench is disposed and engaged atop the upper terminus of the powered vertical spindle of the vertical milling machine. The powered spindle wrench has a socket shaped and sized to engage the drawbar of the upper spindle terminus on signal. The tool holder is secured in and engaged in the spindle tapered aperture at the lower spindle terminus. On pneumatically powering and rotating the upper drawbar terminus of the spindle, the drawbar is unlocked and the tool holder can be removed from the spindle lower terminus. An electrically powered D.C. motor, and a hydraulically powered motor can also be equivalently substituted for the pneumatic motor drive.
Claims4
In a spindle wrench for a vertical milling machine, the improvement comprising:
- a platform linear member having a first and second end terminus and a linear axis of symmetry there between,
- a first vane member pivotally secured normal and central to said first platform member end terminus,
- a second vane member pivotally secured normal and central to said first platform member end terminus and disposed parallel to said first vane member,
- a lever arm secured normal in and to said second vane member, providing manual pivoting torque to said vane member,
- a rod securing means pivotally adapted and secured in a slotted aperture disposed at said second end terminus of said platform member, said rod securing means pivoting normal to said platform linear axis of symmetry,
- a rod means adaptively secured in said rod securing means, providing means for securing said spindle wrench operatively adjacent a drawbar first terminus, and,
- a socket wrench sized and adapted to operatively secure to said drawbar first terminus on signal from said lever arm, said socket wrench rotatively powered and operated by a powered motor adaptively sized and secured through said platform linear member adjacent said linear member first terminus, said powered motor rotated on signal by said first and second vane members, pivotally manually operated by said lever arm in cooperation.
