Abstract
A device for orienting a work surface of a workpiece. The device has a holding means having a receiving surface generally parallel to a plane of reference. The device also has a pulling means for orienting the work surface of the workpiece to the receiving surface of the holding means.
Description
- Many tools and workpieces work better when sharp, and tend to become dull with use over time. Sharpening is an important task in the maintenance of tools and workpieces, especially dies. After tools and workpieces are developed and set up for use in manufacturing or metal stamping, care must be taken to ensure a consistent work product and to maintain tolerances. Trial and error, such as nudging back and forth, is a common yet unsatisfactory means of setting up a work piece for a machining operation and maintaining tolerances. The trial and error method of set up produces inconsistent and unreliable results. It is preferable to orient a work piece to a known or fixed reference. There is a long-felt need for an improved means to sharpen or maintain tools and workpieces.
- The above advantages as well as other advantages not specifically enumerated are achieved by a device for orienting a work surface of a workpiece. The device has a holding means having a receiving surface generally parallel to a plane of reference. The device has a pulling means for orienting the work surface of the workpiece to the receiving surface of the holding means.
- There is also provided a method of sharpening a workpiece including providing a holding means having a receiving surface generally parallel to a plane of reference. The method includes providing a pulling means for orienting the work surface of the workpiece to the receiving surface of the holding means, wherein the work surface of the workpiece is sharpened.
- There is also provided a device for orienting a work surface of a workpiece having a holding means having a receiving surface generally parallel to a plane of reference. The device also has holding region on the holding means. The device has a pulling means for orienting the work surface of the workpiece to the receiving surface of the holding means.

Unless otherwise specified or made apparent by the context of the discussion, such terms and other directional terms should be interpreted with reference to the figure(s) under discussion. Such terms are not intended as a limitation on the position in which the invention or components may be used. Indeed, it is contemplated that the components of the invention may be easily positioned in any desired orientation for use. Likewise, numerical terms such as for example “first”, and “second” are not intended as a limitation or to imply a sequence, unless otherwise specified or made apparent by the context of the discussion.
- One use of this invention is to establish a parallel plane for which to reference a workpiece. This is useful to eliminate an undesirable angle on the workpiece, such as for example on the top surface of the workpiece. The term “workpiece” is understood to include something that has been, or is in the process of being processed, worked on or manufactured. The workpiece may be a tool that has been, or is in the process of being sharpened. The term “tool” is understood to include something (such as for example an instrument or apparatus) used in performing an operation or task. The invention is useful in facilitating the transfer of parallelism. The invention is useful in orienting the work-surface of the workpiece at a desired angle. More specifically, the invention is useful in orienting a dull portion, such as for example a dull surface, of a tool to facilitate more consistent sharpening or shimming of the tool. A tool or workpiece is understood as sharp if the tool is adapted to cutting or piercing or has a comparatively thin keen edge or fine point.
- Referring now to the drawings, there is illustrated in
FIGS. 1 through 7 a parallel surface jig, indicated generally at 20, according to the invention. The illustratedparallel surface jig 20 includes abase 24 and anarm 28 secured to thebase 24 by afirst shoulder bolt 32 and asecond shoulder bolt 36. The term “bolt” is understood to include structures which are generally like or have a bar, rod, pin or cylinder. Thefirst shoulder bolt 32 and thesecond shoulder bolt 36 are stabilizing means for thearm 28. The term “stabilizing” is understood to include structures or capacity for holding generally steady. Thearm 28 is moveably connected to thefirst shoulder bolt 32 and thesecond shoulder bolt 36. Thearm 28 may be slid along the available length of thefirst shoulder bolt 32 and thesecond shoulder bolt 36. - The
base 24 is shown positioned on a granite table 40. Granite tables are employed in tool and die applications for their ability to resist warping and maintain a generally flat surface. Granite tables tend to have relatively few, if any, raised areas or depressions and also have a relatively smooth or even surface. It is this surface of the granite table that supports thebase 24. The granite table 40 provides a type of plane of reference from which parallelism may be measured and/or established. Any suitable table, plane of reference, or the like may be employed. - The
base 24, best seen inFIGS. 2 through 4 , may include abeveled edge 44 around the periphery of atop surface 48 of thebase 24. Thetop surface 48 of thebase 24 is shown generally parallel to the surface of the granite table 40. Thebase 24 may also include agroove 52 around the periphery of a mid-portion of thebase 24 to facilitate handling and/or positioning of thebase 24. Thegroove 52 is aesthetically pleasing and is useful particularly when thebase 24 is portable. The illustratedbase 24 also includes afirst hole 56 and asecond hole 60. Thefirst hole 56 is provided to support thefirst shoulder bolt 32. Thesecond hole 60 is provided to support thesecond shoulder bolt 36. The illustratedfirst hole 56 andsecond hole 60 do not go all the way through thebase 24, but instead may seat on the ledge provided. - The
arm 28, best seen inFIGS. 5 and 6 , includes afirst hole 64 and asecond hole 68. Thefirst hole 64 and thesecond hole 68 of thearm 28 may be generally aligned with thefirst hole 56 and thesecond hole 60 of the base 24 to facilitate placement of thefirst shoulder bolt 32 and thesecond shoulder bolt 36. The illustratedarm 28 also includes adepression 72 therein. Thefirst hole 64 and thesecond hole 68 support thefirst shoulder bolt 32 and thesecond shoulder bolt 36, respectively. It will be appreciated that the illustratedfirst hole 64 and thesecond hole 68 go all the way through thearm 28. Thedepression 72 is provided to support amagnet 76. - The
arm 28 is a holding means for aworkpiece 84. Thearm 28 includes a receivingsurface 80. The receivingsurface 80 of thearm 28 may be spaced apart from themagnet 76. Themagnet 76 is a pulling means. Other suitable pulling means may be employed. An electromagnet may also be employed as a pulling means. The term “electromagnet” is understood to include a magnet which has a coil of wire wrapped around a suitable metal core that is magnetized when current flows through the wire. A vacuum may also be employed as a pulling means. The term “vacuum” is understood to include an area in which the air pressure is below that of the surrounding atmospheric pressure. When a vacuum is employed, there may be provided one or more holes in the receivingsurface 80 to allow the vacuum to act on theworkpiece 84. - The illustrated
arm 28 is adjustable along a vertical axis. The illustratedarm 28 may be adjusted up and down and may be provided with a tightening means 88 to selectively fix thearm 28 in a desired position. Athird hole 92 may be provided to support the tightening means 88. The tightening means 88 may be used to selectively decrease and increase the diameter or other such dimension of thefirst hole 64 and thesecond hole 68 to selectively tighten and loosen the fit of thearm 28 with thefirst shoulder bolt 32 and thesecond shoulder bolt 36. Thefirst shoulder bolt 32 and thesecond shoulder bolt 36 prevent thearm 28 from rotating horizontally. Thefirst shoulder bolt 32 and thesecond shoulder bolt 36 may also provide rigidity to thearm 28. - Referring also to
FIG. 7 , theworkpiece 84 has awork surface 96. Thework surface 96 of theworkpiece 84 is positioned generally flush with the receivingsurface 80 of thearm 28. When thework surface 96 is generally flat, as is the case with theworkpiece 84 shown inFIG. 7 , positioning thework surface 96 generally flush with the receivingsurface 80 of thearm 28 assures that thework surface 96 is generally parallel to awork surface 100 of the granite table 40. This is because receivingsurface 80 of thearm 28 is generally parallel to thework surface 100 of the granite table 40. Because thework surface 100 of the granite table 40 defines a plane of reference, thework surface 96 of theworkpiece 84 is oriented generally parallel to the plane of reference. Thework surface 96 of theworkpiece 84 is held in position by themagnet 76 or other suitable holding means. - Referring also to
FIGS. 8 and 9 , theworkpiece 84 is being held in a desired position by asine vise 98 with thework surface 96 of theworkpiece 84 generally parallel to thework surface 100 of the granite table 40. Thesine vise 98 is one suitable holding apparatus. A precision vise may also be employed. It will be appreciated that the sine vice is employed to hold and/or position thework surface 96 of theworkpiece 84 in a desired orientation or position. However because themagnet 76 is holding thework surface 96 generally parallel to thework surface 100 of the granite table 40, the sine vice is not needed to position theworkpiece 84 with respect to thearm 28. - Referring also to
FIG. 10 , once thework surface 96 of theworkpiece 84 is oriented generally parallel to the plane of reference, theworkpiece 84 can be moved into position with respect to agrinding wheel 104 for sharpening. It will be noted that the setup, such as for example theworkpiece 84 and the holding apparatus holding theworkpiece 84, can be moved into position with respect to thegrinding wheel 104 for sharpening. It will be appreciated that the parallelism of thework surface 100 of the granite table 40 has been transferred to thework surface 96 of theworkpiece 84 for a more precise sharpening with thegrinding wheel 104. - The
grinding wheel 104 may be employed with a magnetic table 108 as shown. For sharpening, theworkpiece 84 may be moved back and forth laterally, as shown byarrows grinding wheel 104 spins, as shown byarrow 120, thegrinding wheel 104 acts on thework surface 96 of theworkpiece 84 to grind, and thereby sharpen or otherwise act on, thework surface 96. Thesine vise 98 is removed fromFIG. 10 for purposes of clarity. It will be appreciated that thework surface 96 of theworkpiece 84 is still oriented generally parallel to the plane of reference even though theworkpiece 84 is not shown supported by thework surface 100 of the granite table 40. Little or no nudging of theworkpiece 84, or “trial and error” in the positioning of theworkpiece 84 for sharpening or processing, is necessary with use of the present invention. In operation, thegrinding wheel 104 may be employed to grind thework surface 96 and thereby sharpen theworkpiece 84. The invention is useful for orienting thework surface 96 of theworkpiece 84 to the receivingsurface 80 of the holding means, such as thearm 28. - It will be appreciated that a block of a predetermined dimension, or other suitable standard, can be placed between
work surface 100 of the granite table 40 and the receivingsurface 80 of thearm 28. Thefirst shoulder bolt 32 and thesecond shoulder bolt 36 and the tightening means 88 assist to selectively fix thearm 28 in a desired position and/or height. - Referring now to
FIG. 6 a, an alternate embodiment of the arm 28 a is shown. The arm 28 a functions in an analogous fashion to thearm 28 shown inFIG. 6 . It will be noted that the receiving surface 80 a of the arm 28 a includes a holding region 81 a. The receivingsurface 80 of thearm 28 shown inFIG. 6 is generally planar. The receiving surface 80 a of the arm 28 a shown inFIG. 6 is shown generally parallel with the holding region 81 a. The holding region 81 a allows themagnet 76, or other suitable pulling means, to pull thework surface 96 of theworkpiece 84 generally flush with the holding region 81 a even when theworkpiece 84 may be other than generally flat. For example, theworkpiece 84 may have an inconveniently located weld bead on or near thework surface 96 to be sharpened. Theworkpiece 84 may also be irregularly shaped. The configuration of the arm 28 a allows flexibility in the sharpening or processing of thework surface 96 for an irregularly shapedwork piece 84 or a portion of thework piece 84 that can not be accommodated on thearm 28 shown inFIG. 6 . - The principle and mode of operation of this invention have been described in specific embodiments. However, it should be noted that this invention may be practiced otherwise than as specifically illustrated and described without departing from its scope.
