Abstract
Abstract A grinding wheel provided with first and second tapered outer peripheral surfaces intersecting with each other at a predetermined angle and a reentrant curved surface on the outer edge of the second tapered outer peripheral surface is dressed by rotary dressing apparatus having first and second working rolls. The rotary dressing apparatus comprises a feed carriage slidably mounted on the grinding wheel carriage, means for feeding the feed carriage toward the grinding wheel, a slide base slidably mounted on the feed carriage, means for moving the slide base in a direction perpendicular to the path of the movement of the slide carriage in parallel with a tangent line of the outer periphery of the grinding wheel, a first dressing head including the first working roll and driving means for totating the same, the first working roll having a cup shaped configuration including an annular working surface adapted to work the first tapered outer peripheral surface of the grinding wheel, means for mounting the first dressing head on the slide base to be tiltable about a first axis perpendicular to the path of the movement of the slide base, a second dressing head including the second working roll and driving means for rotating the same, the second working roll having a cylindrical working surface adapted to work the second tapered outer peripheral surface, the outer edge of the cylindrical working surface of the second working roll being adapted to work the reentrant curved surface of the grinding wheel, and means for mounting the second dressing head on the slide base to be tiltable about a second axis substantially parallel with the first axis.

In rotary dressing apparatus for dressing a grinding wheel which is mounted on a grinding wheel carriage and is provided with first and second tapered outer peripheral surfaces intersecting with each other at a predetermined angle and a reentrant curved surface on the outer edge of said second tapered outer peripheral surface with first and second working rolls, the improvement which comprises a feed carriage slidably mounted on said grinding wheel carriage, means for feeding said feed carriage toward said grinding wheel, a slide base slidably mounted on said feed carriage, means for moving said slide base in a direction perpendicular to the path of the movement of said feed carriage in parallel with a tangent line of the outer periphery of said grinding wheel, a first dressing head including said first working roll and driving means for rotating the same, said first working roll having a cup shaped configuration including an annular working surface adapted to work said first tapered outer peripheral surface of said grinding wheel, means for mounting said first dressing head on said slide base to be tiltable about a first axis perpendicular to the path of the movement of said slide base, a second dressing head including said second working roll and driving means for rotating the same, said second working roll having a cylindrical working surface adapted to work said second tapered outer peripheral surface, the outer edge of said cylindrical working surface of said second working roll being adapted to work said reentrant curved surface of said grinding wheel, and means for mounting said second dressing head on said slide base to be tiltable about a second axis substantially parallel with said first axis.
Claim 2
Dependent Claim
281 words
In rotary dressing apparatus for dressing a grinding wheel which is mounted on a grinding wheel carriage and is provided with first and second tapered outer peripheral surfaces intersecting with each other at a predetermined angle and a reentrant curved surface on the outer edge of said second tapered outer peripheral surface with first and second working rolls, the improvement which comprises a feed carriage slidably mounted on said grinding wheel carriage, means for feeding said feed carriage toward said grinding wheel, a slide base slidably mounted on said feed carriage, means for moving said slide base in a direction perpendicular to the path of the movement of said feed carriage in parallel with a tangent line of the outer periphery of said grinding wheel, a first dressing head including said first working roll and driving means for rotating the same, said first working roll having a cup shaped configuration including an annular working surface adapted to work said first tapered outer peripheral surface of said grinding wheel, means for mounting said first dressing head on said slide base to be tiltable about a first axis perpendicular to the path of the movement of said slide base, a second dressing head including said second working roll and driving means for rotating the same, said second working roll having a cylindrical working surface adapted to work said second tapered outer peripheral surface, the outer edge of said cylindrical working surface of said second working roll being adapted to work said reentrant curved surface of said grinding wheel, and means for mounting said second dressing head on said slide base to be tiltable about a second axis substantially parallel with said first axis.
Claim 3
Dependent Claim
76 words
The rotary dressing apparatus according to claim 1 wherein said first dressing head is pivotally mounted on a pivot pin carried by an adjusting plate which is mounted on said slide base, and said adjusting plate is provided with a plurality of arcuate slots about said pivot pin whereby after said first dressing head has been adjusted about said pivot pin, the same is fixed to the adjusting plate by bolts extending through said arcuate slots.
Claim 4
Dependent Claim
36 words
The rotary dressing apparatus according to claim 2 wherein said adjusting plate is adjustably secured to said slide base so as to adjust the position of said first dressing head with respect to said grinding wheel.
Claim 5
Dependent Claim
58 words
The rotary dressing apparatus according to claim 1 wherein said slide base is supported on said feed carriage through a slide surface extending in a direction parallel to a tangent line of the periphery of said grinding wheel and wherein a piston-cylinder assembly is mounted on said feed carriage for sliding said slide base along said slide surface.
Claim 6
Dependent Claim
84 words
The rotary dressing apparatus according to claim 1 wherein said second dressing head is pivotally mounted on a second pivot pin carried by a second adjusting plate which is mounted on said slide base, and said second adjusting plate is provided with a plurality of second arcuate slots about said second pivot pin whereby after said second dressing head has been adjusted about said second pivot pin, the same is fixed to the second adjusting plate by bolts extending through said second arcuate slot.
Claim 7
Dependent Claim
80 words
The rotally dressing apparatus according to claiM 5 wherein said second adjusting plate is provided with elongated slots and a projection on one end and wherein a pair of adjusting bolts are provided on said slide base to engage said projection, whereby the angular position of said second working roll with respect to said grinding wheel is adjusted by said adjusting bolts, thereafter the second adjusting plate is fixed to the slide base by bolts extending through said elongated slots.
Claim 8
Dependent Claim
63 words
The rotary dressing apparatus according to claim 1 wherein said feed carriage is mounted on said grinding wheel carriage through a base plate which is adjustably secured to said grinding wheel carriage, and is provided with a slide surface which is parallel with a line passing through the axis of said grinding wheel, and said slide carriage is moved along said slide surface.
