sum 1 OF 2 ANDREW WEINING 1O 19 3 M 4%4 4 a PATENTED AUS 8 I972 SHEET 2 OF 2 ANDREW WElNING WHEEL DRESSING FIXTURE STATEMENT OF INVENTION This invention relates to grinding machines and, more particularly, to dressing fixtures for grinding machines.
STATEMENT OF PRIOR ART,
This patent application is an improvement over US. Pat. No. 3,028,853.
OBJECTS OF THE INVENTION.
It is an object of the invention to provide an improved grinding machine fixture.
Another object of the invention is to provide an improved grinding machine wheel dressing fixture.
Another object of the invention is to provide an improved grinding machine fixture which is simple in construction, economical to manufacture, and simple and efficient to use.
With the above and other objects in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportions, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.
GENERAL DESCRIPTION OF THE DRAWINGS FIG. 1 is a side view of the fixture according to the invention shown supported on the grinding machine.
FIG. 2 is an end view of the fixture shown in FIG. 1.
FIG. 3 is a view similar to FIG. 1 of another embodiment of the invention.
FIG. 4 is a side view of the fixture shown in FIG-3.
FIG. 5 is a top view of part of the fixture shown in FIG. 4.
FIG. 6 is an end view of part of the fixture shown in FIG. 5.
DETAILED DESCRIPTION OF THE DRAWINGS Now with more particular reference to the drawings, in the embodiment of the invention shown in FIGS. 1 and 2, the wheel dresser 11 is shown supported on a grinding machine 10. The grinding machine has a wheel 30 supported on a shaft; The outer end of the grinding machine at 19 is circular and receives the collar 13 which may be clamped in place by means of the set screws 31. The collar has ways 15 fixed to it and these ways slidably receive the dressing tool support bracket 20. The bracket threadably receives the threaded shaft 18 which has a hand wheel 17 on its upper end. Thus the bracket 20 will slide up and down on the ways 18. The non-circular rod 21 which is actually square in cross section in the preferred embodiment supports the tool support 29. The tool support 29 has the dressing tool 16 fixed to it which may have a diamond point. The bracket 33 is fixed to the sleeve 13 by means of screw 14. A washer 22 limits the outward sliding movement of the tool support 29 and the screw 23 holds the washer 22 in place. The tool support 29 has the plates 26 affixed to its side by screws and the felt 34 is clamped under plates 26 and this felt wipes foreign material from the support way 21. The support ways may be tightened so that the slot 36 closes by means of the screw 37.
In the embodiment of the invention shown in FIGS. 3, 4 and 5, a fixture much like that shown in FIGS. 1
and 2, is shown and corresponding parts have 100 added thereto to indicate the corresponding parts in FIGS. 1 and 2. The sleeve 113 is shown having the set screws 131 which may clamp it in place to a grinder as in FIG. 1. The bracket 112is fixed to the sleeve and ways 115 are fixed to the bracket. The tool support 120 slides up and down on the ways and it has a non-circu- The slot in link 141 acts as a second adjustment means to move the tool 116 in a direction parallel to the axis of rotation of the wheel. The screw 118 acts as a third adjustment means to move the tool in a direction perpendicular to the axis of rotation of the wheel. The ways 120 receive the dovetail and slide up and down on it, moved by the threaded screw 118 having hand wheel 117. The dressing tool 116 is supported in the tool support 129 in the same manner as in FIG. 2. Thus the tool may be adjusted in a third direction at an angle to the axis 141 of the grinding wheel at an angle to the axis of rotation. The cutting tool 1 16 may be adjusted parallel to the axis and perpendicular to the axis 141, as in the other embodiment.
The foregoing specification sets forth the invention in its preferred practical forms but the structure shown is capable of modification within a range of equivalents without departing from the invention which is to be understood is broadly novel as is commensurate with the appended claims.
The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
l. A fixture for a grinding machine having a spindle housing,
a bearing carried by said housing rotatably supporting a spindle to which a grinding wheel is secured, said fixture comprising,
in combination, a bracket for attachment directly to and concentrically around said spindle housing,
a dressing tool for said grinding wheel,
a first adjustment means for changing the position of said dressing tool in a plane passing through the axis of rotation of said grinding wheel and at an acute angle to the axis of rotation of said wheel,
and a second adjustment means for changing the position of said dressing tool in a direction parallel to the axis of said grinding wheel,
and a third adjustmentmeans for changing the position of said dressing tool in a direction perpendicular to the axis of said grinding wheel,
said means for changing the position of said dressing tool parallel to'the axis of said grinding wheel comprising a non-circular bar fixed to said fixture and 3 4 a tool supporting member slidably received on said said dressing tool to said wheel comprises, noncircula-r a link pivotally supported on said first adjustment stop means on the ends of said bar limiting the outward movement of said tool on said bar. 2. The fixture recited in claim 1 wherein a fourth ad- 5 justment means for changing the angular position of means at one end, the other end of said link being pivotally attached to said non-circular type bar.
