DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIGS. 1 through 5 thereof, a new grinding device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 5, the electrode grinding system 10 generally comprises a vise 12 that may be mounted to a support surface. The support surface may comprise a work bench or the like. A grinder 14 is provided and a grinding wheel 16 is rotatably coupled to the grinder 14. The grinding wheel 16 comprises a diamond grinding wheel. The grinder 14 has an output shaft 18 and the grinding wheel 16 is rotatably coupled to the output shaft 18. The grinding wheel 16 has a grinding surface 20 and a peripheral edge 22. The grinder 14 may comprise a hand-held angle grinder or the like.
A guide 24 is coupled to the grinder 14 and the grinding wheel 16 is positioned within the guide 24. The guide 24 is positionable in the vise 12 such that the grinding wheel 16 is retained in a selected orientation. The guide 24 comprises a plate 26 that has a first surface 28 and a second surface 30. The plate 26 is coupled to the grinder 14 and the output 18 shaft extends through the plate 26. The plate 26 has an aperture 32 extending through the first surface 28 and the second surface 30. The aperture 32 is aligned with the peripheral edge 22 of the grinding wheel 16.
A cover 34 is provided that has a first wall 36 and a peripheral wall 38. The peripheral wall 38 is coupled to and extends away from the first wall 36. The peripheral wall 38 is coextensive with an outer edge 40 of the first wall 36. The peripheral wall 38 has a first lateral side 42, a first longitudinal side 44 and a distal edge 46 with respect to the first wall 36.
The first wall 36 has an opening 48 extending therethrough and the opening 48 is substantially coextensive with the first longitudinal side 44. The opening 48 is aligned with an intersection 50 of the first longitudinal side 44 and the first lateral side 42. The opening 48 extends downwardly along the first longitudinal side 44 to define a first bounding edge 52 of the opening 48. The first bounding edge 52 slopes downwardly from the intersection 50. The first bounding edge 52 may slope at an angle ranging between approximately fifteen degrees and thirty degrees. The opening 48 additionally extends along the first lateral side 42.
The distal edge 46 abuts the first surface 28 of the plate 26 such that the grinding surface 20 is substantially exposed in the opening 48. A plurality of fasteners 54 is provided. Each of the fasteners 54 may extend through the first wall 36 and engage the plate 26. Thus, the cover 34 is removably coupled to the plate 26. Each of the fasteners 54 may comprise a screw or the like.
An electrode 56 is provided and the electrode 56 may be coupled to a welder. The welder may comprise a TIG welder or the like and the electrode 56 may comprise a TIG electrode. The electrode 56 has a first end 58 and the electrode 56 is comprised of tungsten. The electrode 56 is insertable through the opening 48 and the aperture 32 such that the peripheral edge 22 of the grinding wheel 16 abrades the electrode 56 at a selected point. Thus, the electrode 56 may be cut to a desired length.
A drill 60 is provided and the electrode 56 is positioned in the drill 60. The drill 60 is actuatable to rotate the electrode 56 about a longitudinal axis extending through the drill and the first end 58. The drill 60 is positioned such that the electrode 56 frictionally engages the grinding wheel 16. Thus, the grinding wheel 16 shapes the electrode 56. The drill 60 may comprise a cordless drill or the like.
The electrode 56 is tilted to match a slope of the first bounding edge 52 of the opening 48. The electrode 56 is manipulated such that the first end 58 frictionally engages the grinding surface 20. Thus, the first end 58 is ground at an angle that matches the slope of the first bounding edge 52. A collete 62 is provided and collete 62 may be selectively attached to the drill 60. The electrode 56 may be attached to the collete 62 thereby spacing the electrode 56 from the drill 60. Thus, the electrode 56 may be ground to a length of less than 3 cm.
In use, guide 24 is positioned in the vise 12 such that the grinding surface 20 is positioned at a selected orientation. The electrode 56 is positioned in the drill 60 and the grinder 14 is turned on. The drill 60 is actuated to rotate the electrode 56 and the first end 58 of the electrode 56 is positioned to frictionally engage the grinding surface 20. The drill 60 is manipulated such that the electrode 56 is tilted at an angle that matches the slope of the first bounding edge 52. Thus, the first end 58 of the electrode 56 is shaped at an angle required for TIG welding. The electrode 56 is ground when the electrode 56 becomes contaminated during welding and when the first end 58 of the electrode 56 needs to be reshaped. The electrode 56 may be held by hand when the electrode 56 is positioned against the grinding wheel 16.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, system and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
