Abstract
Description
- This invention is related to a chuck for connecting an end mill to a drive spindle. The chucking structure includes a cone that is received in a rotating spindle, a shank that is telescopically received in the cone and threadably received in a tool holder body. A retention knob joins the cone to the tool holder body by expanding a collar on the cone into an opening in the tool holder body as the retention knob is rotated.
- Several forms of chucking structures are known for connecting an end mill to a rotating spindle, generally using a tapered body that is received in a tapered opening in the spindle.
- Art that has addressed this problem include U.S. Pat. No. 6,394,466 issued May 28, 2002 to Masakazu Matsumoto et al. for an End Mill Chucking Structure, and U.S. Pat. No. 6,923,451 issued Aug. 2, 2005 to Masahiro Taguchi et al. for a Tool Holder.
- The broad purpose of the present invention is to provide a tool holder chucking structure comprising a minimal number of components, and usable with a variety of commercially available spindles.
- Still further objects and advantages of the invention will become readily apparent to those skilled in the art to which the invention pertains upon reference to the following detailed description.
- The description refers to the accompanying drawings in which like reference characters refer to like parts throughout the several views, and in which
-
FIG. 1 illustrates a tool holder embodying the invention; -
FIG. 2 is a longitudinal sectional view through the tool holder ofFIG. 1 ; -
FIG. 3 is an exploded view of the major components of the tool holder; -
FIG. 4 is a sectional view as seen along lines 4-4 ofFIG. 1 ; -
FIG. 5 is an enlarged view illustrating the manner in which the cone is joined to the tool holder body; and -
FIG. 6 is an enlarged fragmentary sectional view of the neck and tapered section of the shank. -
FIG. 1 illustrates apreferred tool holder 10 for joining a tool, such asend mill 12, to arotatable drive spindle 14, shown in phantom. The tool can be any of a variety of rotatable cutting tools. The spindle is conventional and is used in a variety of commonly used power sources. -
Tool holder 10 comprises aretention knob 16, acone 18, ashank 20 and atool holder body 22. - Referring to
FIGS. 1 and 2 ,body 22 has an axial tool-receivingcylindrical bore 24. The lower end ofbore 24 is adapted to receiveend mill 12. A pair of longitudinally offset threadedfasteners body 22, provide means for joiningend mill 12 to thetool holder body 22. Bore 24 has ablind end 29. - The upper end of
body 22, as viewed inFIG. 2 , has a stepped, shank-receiving bore 30. Bore 30 is axially aligned withbore 24, and has an upperannular shoulder 32 and a smaller, lowerannular seat 34.Seat 34 is at the upper end of a female threadedsection 36. - Bore 30 has a
cylindrical wall 38 betweenshoulder 32 andseat 34. Bore 30 has acylindrical wall 40 betweenshoulder 32 and anannular flange 42.Flange 42 abuts thelower surface 44 ofspindle 14, when the tool is being rotated. - Shank 20 has a lower threaded
end 46 that engages threadedsection 36. Threadedend 46 joins anannular collar 48. Collar 48 has alower face 49 that abutsseat 34 when the shank is fully joined tobody 22. The outercylindrical surface 49 a ofcollar 48 is slidably received incylindrical wall 38. - Referring to
FIG. 6 , the shank has a narrowcylindrical section 50 that extends from theupper face 51 of the collar to the lower end of atapered section 52. Taperedsection 52 extends to agage line 54. The balance of the shank is cylindrical fromgage line 54 to theupper end 56 of the shank. The upper end of the shank has an internal threadedbore 58 which receives the lower threadedend 60 ofretention knob 16. -
Cone 18 has an upper bearingsurface 62 for seating the retention knob, and afrustoconical wall 64 which progressively enlarges in diameter to agage line 66. The outercylindrical surface 68 of the cone extends fromgage line 66 to a lower annularflat face 70.Cylindrical surface 68 slidably engagescylindrical wall 40 of the body. The cone has anaxial bore 71. - Referring to
FIGS. 3 and 6 , the lower end 72 of the cone forms ahollow neck 74. Theouter surface 75 ofneck 74 is cylindrical and is received in anannular chamber 76 existing betweenwall 40 of the body andtapered section 52 of the shank. Neck 74 has a pair ofaxial splits 78 and 79 (FIG. 4 ) which permit theneck 74 to radically expand. Neck 74 also has atapered bore 80 that slidably engages thetapered section 52 of the shank. - The arrangement is such that as the cone is biased toward the shank collar,
neck 74 is expanded by the tapered section of the shank in the direction ofarrows flat face 85 of the neck and theupper face 51 of the collar. Further, a clearance exists betweenflat face 70 of the cone and theupper shoulder 32 of the body. - Referring to
FIG. 6 , the lower end of the neck overlaps the narrowcylindrical section 50 of the shank so the extreme lower end of the neck is biased radically inwardly in the direction ofarrows
