Abstract

A hollow housing (20) slidingly retains an extendable body (22) through an open end allowing forward and aft movement. A rotatable tool holding head (34) is adjustably connected to the body (22) and is free to rotate up to 180 degrees. Extendable adjustment in the form of a threaded shaft (44) and handwheel (46) provide the manual expansion movement by rotation of the wheel (46) located on the opposite end as the body (22). Radial movement is afforded by a similar handwheel (50) attached to the head (34) through a drive shaft (48). A slidable end (36) is attached to the head (34) and contains a removable cutting tool (38) that rotatably cuts away material from a rotated workpiece. In a variation of the body (20) an angular shape is added with or without a mounting slot. Also, a pair of servo motors (62) and (64) may replace the handwheels for electromechanical adjustment of the device incorporating another embodiment.

Dependent claims

An adjustable tool holding device for machine tools comprising:

(a) a hollow housing having one end open,
(b) an extendable body having an arcuate recess on one end, said body slideably disposed within said housing through said open end allowing longitudinal line fore and aft movement therewithin,
(c) a pivoting tool holding head assembly contiguously abutting said arcuate recess of said body so as to be pivotable about an axis perpendicular to the longitudinal direction, said tool holding assembly having a cutting tool removably affixed thereon and holding said cutting tool in a radially fixed position, relative said axis
(d) body adjustment means integrally disposed within said housing and extendable body for urging said body fore and aft within said housing controlling the longitudinal position of said cutting tool in relation to said housing;
and,
(e) tool holding head assembly adjustment means integrally disposed within said housing and extendable body for pivoting said tool holding head about said axis controlling the angular position of said cutting tool in relation to said housing.
