Description
- This is a continuation in part of U.S. application Ser. No. 09/812,615 now U.S. Pat. No. ______.
- 1. Field of the Invention
- The present invention relates to a tool for finishing and/or plateauing an outside diameter surface of a cylindrical workpiece by means of a size-adjustable cylindrical bore having abrasive particles for finishing the workpiece, a method of plateauing an O.D. surface and a workpiece with a plateaued O.D. surface.
- 2. Background Art
- There is considerable prior art relating to the honing, deburring, lapping, finishing, and superfinishing of bores by means of various tooling structures. However, there is no known prior art which addresses problems associated with the accurate finishing of an outside diameter (O.D.) surface of a cylindrical workpiece for close tolerancing. For example, a pulley hub for a timing belt may require close tolerancing on its O.D. surface, and may require accurate concentricity of the O.D. surface with respect to the central axis of the hub. This close tolerancing may not be achieved with existing prior art turning or lathing operations.
- Accordingly, there remains a need in the art for inexpensive machine tools for finishing O.D. surfaces of cylindrical workpieces in a manner in which precise tolerancing can be achieved and concentricity with respect to a central axis of the workpiece can be achieved.
- The present invention overcomes the above-referenced shortcomings of prior art O.D. surface finishing operations by providing a tool for plateauing the O.D. surface of a cylindrical workpiece which includes an adjustable interior bore having abrasive particles thereon for accurately finishing the cylindrical workpiece.
- As used herein, the term “finishing” is used to refer to lapping, deburring, polishing, or machining or other operations in which substantially improved surface characteristics are achieved.
- Preferably, the tool comprises a rotatable substantially cylindrical member (or “cylindrical portion”) having an inner work-engaging surface adapted for finishing the O.D. surface of the cylindrical workpiece. The inner work-engaging surface includes abrasive particles thereon and defines a bore to receive the workpiece. The substantially cylindrical member includes at least one longitudinal split permitting radial expansion and contraction of at least part of the cylindrical portion for workpiece O.D. finish adjustment.
- An adjustment nut is threaded onto the substantially cylindrical member. The adjustment nut and substantially cylindrical member include at least one tapered adjustment surface therebetween which is operative as a cam to facilitate the expansion and contraction as the adjustment nut is rotated with respect to the substantially cylindrical member.
- In one embodiment, the tapered adjustment surface is formed on an outside surface of the substantially cylindrical member. The adjustment nut includes at least one preload ring made of a compliant material engaged with the tapered adjustment surface to provide an adjustable compressive force on the substantially cylindrical member as the adjustment nut is rotated with respect to the substantially cylindrical member. This embodiment is particularly used for superfinishing the O.D. surface.
- In another embodiment, the substantially cylindrical member comprises a tapered outer surface and the adjustment nut comprises a tapered portion slidably engageable with the tapered outer surface as the nut is rotated with respect to the substantially cylindrical member to provide an adjustable compressive force on the substantially cylindrical member as a result of interference-type engagement between the tapered portion of the nut and the tapered outer surface of the substantially cylindrical member. This structure is more rigid than the above-described embodiment, and is used primarily for rough-cutting, as opposed to superfinishing.
- Accordingly, an object of the invention is to provide a tool for accurately finishing an O.D. surface of a cylindrical workpiece.
- Another object of the invention is to provide a tool for accurately finishing an O.D. surface of a cylindrical workpiece which includes a cylindrical member defining a bore bordered by abrasive particles to receive and finish the workpiece.

- Referring to FIGS.1-5, an O.D. finishing
tool 10 is shown in accordance with a first embodiment of the invention for plateauing an outside diameter (O.D.) surface 12 of acylindrical workpiece 14. The primary function of plateauing is to remove the “peaks” of a surface finish. - The
finishing tool 10 comprises abody 16, which includes ashank portion 18, with a substantially cylindrical portion (or “member”) 20 extending from theshank portion 18. - The substantially
cylindrical portion 20 includes an inner work-engagingsurface 22 withabrasive particles 24 thereon for finishing the O.D.surface 12 of theworkpiece 14. Preferably, theabrasive particles 24 are diamond chips. - The inner work-engaging
surface 22 defines abore 26 to receive theworkpiece 14, and includes a plurality of longitudinally extendingsplits 28, which are shown in FIGS. 4 and 5. Thelongitudinally extending splits 28 are configured to permit radial expansion and contraction of at least part of thecylindrical portion 20 for workpiece O.D. finish adjustment. - The inner work-engaging
surface 22 includes a curved lead-inedge 30 to facilitate insertion of theworkpiece 14 into thebore 26. - In the embodiment shown in FIG. 1, the substantially
cylindrical portion 20 includes a tapered outsidesurface 32 which extends approximately the length of the work-engagingsurface 22 along the length of thecylindrical portion 20. - An
adjustment nut 34 is threadedly engaged with the substantiallycylindrical portion 20 along thethreads 36. Accordingly, theadjustment nut 34 is rotatably adjustable with respect to the substantiallycylindrical portion 20 as a result of this threadedengagement 36. As shown in FIG. 3, theadjustment nut 34 also includeswrench flats 38 and aset screw hole 40 for receiving a set screw to secure theadjustment nut 34 in the desired position with respect to the substantiallycylindrical portion 20 when adjusted. - As shown in FIG. 2, the
adjustment nut 34 also includesgrooves rings 46, 48 (or any compressible or spring material), which are preload rings made of a compliant material operative to engage with the tapered outsidesurface 32 of the substantiallycylindrical portion 20 to provide an adjustable compressive force on the substantiallycylindrical member 20 to vary the diameter of thebore 26 for finish adjustment of the O.D.surface 12 of theworkpiece 14. - This embodiment is particularly applicable to superfinishing operations because the O-
rings - By example, in order to improve the finish of the
bore 26, theadjustment nut 34 is rotated with respect to thecylindrical portion 20, which causes the O-rings surface 32, thereby compressing the O-rings surface 32, which provides a compressive force to reduce the width of thesplits 28, thereby improving thebore 26 to ultimately reduce the O.D. of theworkpiece 14 and plateau the surface as theabrasive particles 26 are rotated against the O.D.surface 12. - An alternative embodiment of the invention is shown in FIG. 6. As shown, the O.D.
finish tool 110 is configured for plateauing an O.D.surface 112 of acylindrical workpiece 114. The O.D. finishingtool 110 includes abody 116 having ashank portion 118 and a substantiallycylindrical portion 120. The substantiallycylindrical portion 120 includes an inner work-engagingsurface 122 havingabrasive particles 124 thereon. - The inner work-engaging
surface 122 forms abore 126 to receive theworkpiece 114. The substantiallycylindrical portion 120 includes one or more longitudinally extendingsplits 128 to enable selective radial expansion and contraction of at least part of thecylindrical portion 120 for adjustment of thebore 126 to finish the O.D.surface 112 of theworkpiece 114. - The substantially cylindrical member (portion)120 includes a tapered
outer surface 132. - An
adjustment nut 134 is threadedly engaged with the substantiallycylindrical portion 120 at the threadedportion 136. Theadjustment nut 134 includes aset screw hole 140 for holding theadjustment nut 134 in a desired rotational position with respect to the substantiallycylindrical portion 120. - The
adjustment nut 134 also includes a taperedportion 142 which is slidably engaged with the taperedouter surface 132 of the substantiallycylindrical portion 120 as the nut is rotated with respect to the substantiallycylindrical portion 120 to expand or contract the inner work-engagingsurface 122 for workpiece O.D. finish adjustment. - Accordingly, as a result of the interference-type engagement between the tapered
outer surface 132 of the substantiallycylindrical portion 120 and the taperedportion 142 of theadjustment nut 134, relative sliding engagement of thesurfaces surface 122 as a result of the adjustable compressive forces applied to the substantiallycylindrical member 120 by the taperedportion 142 of theadjustment nut 134. Compressing the O-rings splits 128. - The
tool 110 also includes acoolant aperture 146 formed in asleeve 148 in communication with thebore 126 for carrying coolant to thebore 126 for cooling theworkpiece 114. Alternatively, coolant may be delivered through the distal end of theshank portion 118 as shown in FIG. 6A. - The flushing also removes the surface particles generated by the plateauing process, thereby providing a clean and predictable plateauing value.
- The present invention recognizes that various other means may be provided for providing adjustable compressive forces on a substantially cylindrical portion of a tool for adjustment of an internal bore thereof within the scope of the present invention. Once the means for adjusting the compressive force applied to the substantially cylindrical portion has been appropriately adjusted, the workpiece is inserted into the bore, and the tool is rotated with respect to the workpiece to finish the O.D. surface.
- In an alternative embodiment, the adjustment nut is not threaded to the cylindrical portion, but rather slides axially along the cylindrical portion. A
handle 150 may be provided for manually sliding the nut. This configuration enables quick disengagement of the O.D. finishing tool and eliminates the helical tool marks for applications such as seal surfaces. - FIGS. 8 and 8a show an alternative embodiment of an O.D. finishing
tool 210. Thefinishing tool 210 comprisescylindrical arbor 214 having achannel 216 at a back end and a plurality of finishingelements 218 mounted at a front end, anouter sleeve assembly 220 slidable along thearbor 214 and along the finishingelements 218, and adrawbar 222 that is slidably mounted in the channel. Thedrawbar 222 is operatively connected to across pin 224. - The
outer sleeve assembly 220 comprises acylindrical sleeve 226,cross pin 224, and a plurality ofadjustable elements 228. Preferably, the tool has three adjustable elements. - Each
adjustable element 228 comprises ashoulder screw 230 with aspring 232 around it and anexternal rocker arm 234 operatively connected to thespring 232. Theexternal rocker arm 234 has aroller 236 at its distal end. Theroller 236 slides along an outer surface of a cooperatinginternal lever 238. - Each finishing
element 218 comprises aninternal lever 238 mounted at the front end of thearbor 214. The internal rocker arm pivots about apin 248. Preferably, theouter surface 240 of theinternal lever 238 is concave. As theroller 236 slides forward it moves ahead of thepivot pin 248 and pushes on the front end of theinternal lever 238. Thearm 238 pivots and thework engaging surface 250 is pushed into contact with and engages the workpiece. As the roller slides back, it moves behind thepivot pin 248 and pushes on the back end of theinternal lever 238 which pivots and causes the front end to lift up and to disengage theworkpiece 242. At the front end of theinternal lever 238 is anabrasive surface 244 for engaging and finishing theworkpiece 242. Preferably, theabrasive surface 244 is a diamond pad. Preferably, there is aplastic pad 254 that serves as a bumper when the work engaging element is retracted. - The
cylindrical workpiece 242 is placed at the mouth of thetool 210. Whendrawbar 222 is pushed toward thetool 210,abrasive surfaces 244 on the finishingelements 218 engage theworkpiece 242. As thedrawbar 218 is pulled away from thetool 210, it pulls on thecross pin 220 which pulls theouter sleeve assembly 220 back. The spring loadedadjustable element 228 moves back, theroller 236 of theexternal rocker arm 234 moves behind the pivot point of theinternal lever 238 and the front end of theinternal lever 238 lifts up. As thedrawbar 218 is pushed toward thetool 210, thecross pin 220 pushes theouter sleeve assembly 220 forward. The spring loadedadjustable elements 228 move forward and therollers 236 of theexternal rocker arms 234 move ahead of the pivot point pushing the front end of the internal rocker arm down 238. Theabrasive surfaces 244 engage thework piece 242. - The
tool 210 is then rotated finishing the O.D.surface 246 of the workpiece. Thearbor 214 is connected to arotable spindle 256. Thespindle 256 is rotated which rotates thetool 210 causing theabrasive surface 244 to rotate against theworkpiece 242. The outer-diameter of theworkpiece 242 is plateaued by thetool 210. - To cool the tool, coolant could be pumped through the
channel 216 in the spindle as shown in FIG. 8b, pumped through asleeve 258 in communication with thechannel 216 as shown in FIG. 8c, or even pumped through the cylindrical workpiece. - These O.D. surface finishing tools are operative to “plateau” the surface of the workpiece to generate an Rpk value which is 3-10 times smaller than Rvk, thereby producing bearing ratios in excess of 40%, as these terms are described in commonly owned U.S. Pat. No. 6,139,414, which is hereby incorporated by reference in its entirety.
- FIGS.9-12 provide schematic illustrations of surfaces before and after the plateauing operation. A plateau tool may be applied to a common surface, as shown in FIGS. 8a, 8 b, and 10 which has been previously machined where the peaks and valleys (Rvk, Rpk) are substantially equal. The plateauing tool removes only a prescribed amount of peaks to generate a predictable Rpk value without changing the size or geometry of the workpiece (i.e. the roughness average Ra remains the same). With the peaks removed and the valleys still intact to contain oil, this is the ideal condition for many applications.
- As shown in FIGS. 9a and 9 b, as well as FIG. 11, a common surface will have a roughness with an equal distribution of peak height and valley depth.
- As shown in FIGS. 10a, 10 b, and 12, the surface has been plateaued, thereby removing the peaks, and providing a much flatter material ratio curve and generating a Rpk which is 3-10 times smaller than Rvk, thereby producing bearing ratios in excess of 40%. Comparing FIGS. 11 and 12, the peaks P of FIG. 11 have been removed to form the plateaued surface S of FIG. 12, while the roughness average (Ra) remains at 2.4 micrometers, Rpk is reduced from 2.6 to 0.9 micrometers, Rk is reduced from 8.2 to 1.9 micrometers, and Rvk is increased from 2.6 to 9.8 micrometers by the plateauing process.
- While the best modes for carrying out the invention have been described in detail, those familiar with the art to which this invention relates will recognize various alternative designs and embodiments for practicing the invention within the scope of the appended claims.
