Abstract
In the present invention a tubular toolholder shank is releasably held in the bore of a tool support member by a releasable locking mechanism mounted in the bore of the tool support member and receivable in the tubular toolholder shank. The locking mechanism has an actuating member radially extending through the wall of the tubular shank.
Claims13
An apparatus for releasably holding a tubular toolholder shank, said apparatus comprising:
- a tool support member having a forwardly facing surface and a bore intersecting said forwardly facing surface and extending rearwardly therefrom for receiving said tubular toolholder shank;
- a means for releasably locking said tubular toolholder shank into said tool support member, located within said bore and receivable in said tubular toolholder shank;
- said means for locking having a stub member having a passageway therein extending radially along a first radial axis with respect to the longitudinal axis of said bore;
- said stub member having a first aperture and a second aperture circumferentially spaced from said first aperture, and said first and said second apertures radially extending away from the bore wall along a second radial axis and intersecting said passageway;
- a first locking element and a second locking element for releasably abutting with said tubular toolholder shank to releasably lock said tubular toolholder shank onto said support member, respectively located in said first and second apertures;
- and a means for actuating said first and said second locking elements through abutment therewith, reciprocally movable along said first radial axis and engaged in said passageway.
