Abstract
Description
- The invention relates generally to rotatably driven disc brushes.
- It is known to employ a disc brush having a plurality of abrasive filaments, coupled to and driven for rotation by a rotary drive apparatus, for de-burring.
- While the prior art brushes are well-adapted for use on planar surfaces, a problem may occur when the brush is used to de-burr a contoured surface. For example, the interior well portion of an automobile wheel typically includes a raised surface proximate a central portion of the wheel hub. A disc brush having bristles arranged in an annulus surrounding a central portion of a disc is used in the de-burring operation performed on the interior well portion. When the brush is in a pristine condition, the brush functions satisfactorily to de-burr the interior surface of the hub adjacent the raised surface. However, with continued use the brush filaments wear away, to a point where the central portion of the brush disc contacts the raised surface, preventing further use of the brush. In the prior art brushes, the filaments are not completely consumed at the point where the contact between the raised surface and the disc prevents further use of the brush. Consequently, the brush filaments are not fully utilized. For example, if, when the brush is in a pristine condition, the filaments have a length of 5.0 inches, and there are 3 inches of travel between the work piece raised surface and the central portion of the disc when the tips of the filaments operatively engage the work piece, then the disc brush would have to be replaced when the filaments have worn by 3 inches. Thus, of the original 5 inch length, only approximately 3 inches, or 60 percent of the abrasive filament provided, is productively consumed. A need exists therefore to reduce waste and improve utilization of the abrasive filaments of disc brushes used with work pieces having contoured surfaces.
- The invention is a disc brush comprising a disc having a face including at least a first portion and a second portion. A plurality of abrasive filaments are fixed to the first portion, extend generally perpendicularly from the disc, and are arranged around the second portion. The second portion is recessed from the first portion to form a recess having a diameter and axial depth sufficient to receive at least part of a raised portion of a work piece.
- For the purpose of illustrating the invention, there are shown in the drawings an embodiment of the invention which is presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown. In the drawings:
- Figure 1 is a plan view of a disc brush in accordance with a preferred embodiment of the present invention.
- Figure 2 is a cross-sectional view of the disc brush of Figure 1, taken along line 2-2 of Figure 1.
- Figure 3 is a cross-sectional view of a conventional automobile wheel.
- Figure 4 is cross-sectional view of the disc brush of Figures 1 and 2, shown decoupled from a drive apparatus and also shown positioned within an interior well of the conventional automobile wheel of Figure 3 in a position suitable for a de-burring operation of an interior surface of a hub portion of the wheel.
- Referring to the drawings, and initially to Figures 1 and 2, a disc brush in accordance with the present invention is indicated generally by the
reference numeral 10. Thedisc brush 10 comprises adisc 20 having a first face 22 including at least afirst portion 24 and asecond portion 26. Thedisc brush 10 further comprises a plurality ofabrasive filaments 40 fixed to thefirst portion 24 and extending generally perpendicularly from thedisc 20 and arranged around thesecond portion 26 preferably in an annular pattern. Thesecond portion 26 is recessed from thefirst portion 24, forming arecess 28. Therecess 28 has a diameter D1 and axial depth L1 sufficient to receive at least part of a raised portion of a work piece. The recess diameter D1 is preferably in the range of 7.5 to 8.5 inches. The total diameter of thedisc 20 is preferably in the range of 14.5 to 15.5 inches. - The plurality of
abrasive filaments 40 each have afixed end 42 attached to thefirst portion 24 and atip 44. Thefilaments 40 are preferably fabricated from a polymeric base material, such as a linear polyamide (commonly know as nylon) impregnated with an abrasive grit, such as silicon carbide or aluminum oxide. As noted, thefilaments 40 are preferably arranged on the first portion in an annular pattern, preferably in discrete bundles. The radial extent of the annulus preferably corresponds generally to the radial extent of the portion of the working surface to be de-burred. For example, the radial extent of the annulus may comprise an inner radius R1 in the range of 4.5 to 5.0 inches and an outer radius R2 in the range of 7.25 to 7.75 inches. In addition, the brush may, for example, comprise a first set of filament bundles having a total exposed length L2 of 3.75 inches and a second set of filament bundles having a total exposed length L3 of 3.25 inches. Alternatively, if used on a relatively flat work piece, each filament bundle could have the same length. It will, of course, be understood that specific dimensions are given only as illustrative, and are not intended to limit the invention to specific dimensions or ranges of dimensions. Rather, individual dimensions may be chosen as appropriate for particular applications of the brush. - The
disc 20 has acentral axis 12. Thedisc 20 comprises the first face 22 as well as asecond face 30. Thedisc 20 may be fabricated as a single, unitary member. Alternatively, thedisc 20 may be fabricated as an assembly of multiple members, for example, afirst member 34 and asecond member 36 rigidly connected together. Thedisc 20 may be fabricated from any number of materials well known to those of ordinary skill in the art of surface finishing tools, for example, metal, wood, or polymeric materials. A preferred material of construction for thedisc 20 is polypropylene. Theabrasive filaments 40 are affixed to thedisc 20 in a conventional manner well known to the artisan in the field. - The
disc 20 may be operably coupled to the rotary drive device (not illustrated) using any of a number of means well known to the person of ordinary skill in the art. For example, in the preferred embodiment illustrated, thedisc 20 includes anarbor hole 32 by which thedisc 20 is coupled to an arbor (not illustrated) of a rotary drive device (not illustrated). Thearbor hole 32 is circular, preferably with a diameter D2 of approximately 5.9 inches to receive a standard arbor, and is centered about the disccentral axis 12. Alternatively, other forms of drive and other opening shapes, such as square or hexagonal, can be used without departing from the invention. The particular drive device and the manner in which the brush is coupled to the drive device is not critical to the present invention. - In the preferred embodiment illustrated, the
recess 28 and thearbor hole 32 are coaxial, and meet to form a continuous opening extending through thedisc 20. However, the recess depth L1 need not extend to meet thearbor hole 32. Moreover, it is not a requirement of the present invention that thearbor hole 32 be provided, and if provided, the arbor hole need not extend to a depth to meet therecess 20. - The person of ordinary skill in the art will recognize that various means other than the
arbor hole 32 could be employed to couple thedisc brush 10 to a rotary drive device. For example, thedisc 20 could be provided with a rod rigidly fixed to and extending from thesecond face 30. The rod could be received by and coupled to the rotary device. Alternatively, fasteners such as screws could be used to couple thedisc brush 10 to the rotary device. - With reference now to Figure 3, the
disc brush 10 illustrated in Figures 1 and 2 is particularly well-adapted for use with anautomobile wheel 50. Thewheel 50 rotates about an axis ofrotation 52, and typically comprises ahub portion 54 and arim portion 66. Thehub portion 54 has anexterior side 56, visible to an observer outside the automobile (not shown) when thewheel 50 is mounted to the automobile, and aninterior side 58. Thehub portion 54 also has acentral portion 60, where thewheel 50 mounts to the automobile axle assembly (not shown). Typically, forces acting on thehub portion 54 are highest proximate thiscentral portion 60, and it is conventional that thecentral portion 60 will be thicker and more massive than other portions of thehub 54. Frequently, thehub portion 54 will be designed such that theinterior side 58 is contoured, with the interior side of thecentral portion 60 projecting inwardly from a remainder of thehub 54 interior side, thecentral portion 60 thus having an interior raisedsurface 62. Typically, it is not necessary to de-burr the raisedsurface 62, but only a surroundingannular work surface 64. The annular arrangement of thefilaments 40 is chosen to correspond to the extent of thework surface 64 requiring the de-burring operation. Therim portion 66 includes first andsecond rim flanges wheel 50. Awheel well 72 is formed within therim portion 66 andhub portion 54. - With reference now to Figure 4, the
disc brush 10 is shown within thewheel well 72. Thewheel 50 is shown in phantom, and is not as part of the invention. In use thedisc brush 10 is driven for rotation about thecentral axis 12 and simultaneously thetips 44 of theabrasive filaments 40 are brought into contact with theannular work surface 64 of the hubinterior side 58. As theabrasive filaments 40 rotate against thehub 54, thewheel 50 work piece is de-burred. Thedisc brush 10 has a length of travel T between the raisedsurface 62 and thesecond portion 26 wheredisc 20 eventually, with sufficient wear of thefilaments 40, contacts the raisedsurface 62. - The travel T associated with the
disc brush 10 exceeds the corresponding travel T' a prior art brush not provided with the recess would permit. That is, since the recess diameter D1 and depth L1 are sufficiently large to receive at least a part of the raisedsurface 62, thedisc brush 10 enables an additional length of travel relative to a prior art disc, up to an amount equal to the recess depth L1. This additional travel increases the amount of theabrasive filaments 40 which may be productively used before thedisc brush 10 must be replaced. - For example, if the recess depth L1 is chosen to be approximately 0.85 inches, then for the geometry of the preferred embodiment illustrated in conjunction with the wheel geometry illustrated, the length of travel is approximately 2.65 inches. If the
recess 28 was not provided, the length of travel would be approximately 2.65 - 0.85 = 1.8 inches. Thus, of the original 3.75 inch length L1, approximately 1.8/3.75 = 48 percent of the abrasive filament material would be consumed before replacement of a prior art disc brush would be required, compared to 2.65/3.75 = 70 percent of the abrasive filament material in thedisc brush 10 being productively consumed. Thedisc brush 10 of the present invention thus significantly reduces waste ofabrasive fibers 40. As the cost of theabrasive fibers 40 is a significant cost element of thedisc brush 10, a significant decrease in the overall cost of thedisc brush 10 results. - From this disclosure, the artisan will recognize that other types of abrasive media, such as a non-woven abrasives, could be substituted for the
abrasive filaments 40. Further, the artisan will recognize that the present invention need not be applied solely to disc brushes used in de-burring operations, but could be applied to rotary discs adapted for other types of surface finishing operations involving contoured parts. - While the invention has been described and illustrated with respect to the exemplary embodiments thereof, it should be understood by those skilled in the art that the foregoing and various other changes, omissions and additions may be made therein and thereto, without parting from the spirit and scope of the present invention.
