HONING HEAD This invention relates to a multi-finish honing head.
A primary object of this invention is the simultaneous actuation of different finished hones.
Another object of this invention is a simple one-step motion to accomplish the primary object of this invention.
The above and other objects of this invention will become apparent to those skilled in the art after a consideration of a description of a preferred embodiment of this invention taken togetherwith the accompanying drawing wherein: a
FIG. 1 is a cross-sectional view of the device; FIG. 2 is a sectional view taken on line 2-2 of FIG.
FIG. 3 is a sectional view taken on line 33 of FIG. 1; and i FIG. 4 is a cross-sectional view showing alternate stones expanded.
Referring in detail to the drawing, there is shown a honing body having a cylindrical bore 12 through the longitudinal center thereof and a plurality of longitudinal grooves 14 equally spaced along the perimeter thereof (as clearly shown in FIGS. 2-4). An adjustable seat 16 is threadedly positioned within one end of bore 12. Physically engaging seat 16 within bore 12 is a spring 18 or other element capable of exerting a reciprocal force.
Mounted within bore 12 pressing against spring 18 is a longitudinal piston 20 having midportions 22 and end portions 24 in slidable engagement with bore 12. Between each end portion 24 and midportion 22 is conically tapered sections 26 and 28 abutting each other at the smallest diameter section 30.
' A drive shaft 32 is slidably mountedat the other end of bore 12 for exerting a force against the end of piston 20 opposite the end pressing against spring 18 for I reciprocal movement of piston 20 within bore 12. Within each groove 14 is a longitudinal stone holder pressedly secured against the bottom of groove 14 by means of a flexible holding element 42 positioned within a groove 44 connecting each end of each holder 40 to each other thereby exerting a force against honing body 10 directed toward the center longitudinal axis thereof. Each holder 40 is 180 away from another holder 40. One holder 40 of the 180 pair of holders 40 holds a coarse grit stone 46 and the other holder 40 holds a fine grit stone 48.
When driv e sh l t 32 i s driven by conventional means (not shown) forcing piston 20 against spring 18, coniing a pushing force against pins 54 associated with coarse stones 46. While stone holders 40 holding coarse stones 46 are pulled back. into an inoperative position, stone holders 40 holding fine stones 48 are being pushed outward into an operative position by means of the pins 54 being pushed through bores 50 by conically tapered sections 26.
While a preferred embodiment of this invention has been illustrated and described, it should be understood by those skilled in the art that many changes and modifications may be resorted to without departing from the spirit and scope of the invention.
I claim:
1. A honing head, comprising a honing body having a center longitudinal bore, at least one pair of grooves in the outer surface thereof, the longitudinal axes of each said pair of grooves and said bore lying in the same plane, and at least one pair of substantially diametrically opposed bores having the longitudinal axes thereof transverse with the axis of said longitudinal bore and leading from said pair of grooves to said longitudinal bore, honing means slidably secured within each groove of said pair of grooves, opposed conically tapered means slidably mounted within said longitudinal bore, pin means in each of said pair of bores engageable with said honing means and said tapered means respectively, one of said pin means engaging one of the opposed conically tapered means and the other of said pin means engaging the other conically tapered means to selectively and alternatively move said honing means partially out of their respective groove upon back and forth longitudinal movement of said tapered means, and means to selectively move said tapered means back and forth in said longitudinal bore.
2. A honing head as claimed in claim 1 wherein said conically tapered means includes a pair of longitudinally spaced tapered sections each including a pair of conically tapered surfaces abutting at the smallest diameter point of each, one of said pins engaging each end of each of said honing means and a similar tapered surface of each of said tapered sections.
3. A device as claimed in claim 1 including flexible means detachably connected to adjacent ends of said honing means detachably securing said honing means in said grooves.
