Honing mechanism

Claim 3

The apparatus of claim 1, and including drive means for rotating each working member, said drive means comprising a driven shaft connected to each working member, a splined drive shaft operably connected to a source of power, a pair of splined members mounted on the spline drive shaft, and a connecting member connecting each splined member with the respective driven shaft, movement of said working members between said working position and said dressing position acting to move said spline members along said drive shaft to maintain the driving connection between said drive shaft and said driven shafts.

Claim 4

The apparatus of claim 1, wherein said indexing means includes a stop adjustably mounted with respect to the supporting structure, a pair of abutments associated with at least one of said working members, engagement of one of said abutments with the stop acting to limit the movement of the working members when moving toward the dressing position and engagement of the other of said abutments with said stop acting to limit the movement of said working members when moving toward the working position.

Claim 5

The apparatus of claim 3, wherein said indexing means includes means responsive to movement of said working members toward the dressing position for adjusting the position of said stop with respect to said supporting structure, and means responsive to movement of said working members toward said working position for adjusting the position of said stop with respect to said supporting structure, adjustment of the position of the stop serving to adjust the spacing between the working members in the working and dressing positions.

Claim 6

The apparatus of claim 3, wherein said abutments are located on opposite sides of said stop, each working member is mounted on a carriage and said abutments are mounted on one of said carriages.

Claim 7

The apparatus of claim 3, wherein said stop is mounted for rotation with respect to the supporting structure, and said indexing means includes a member connected to each abutment and engageable with the stop to rotate the stop through a predetermined arc and thereby adjust the position of the stop with respect to the supporting structure.

Claim 8

The apparatus of claim 6, wherein said stop is provided with a plurality of circularly arranged openings, and said member comprises an indexing pin and adapted to engage one of said openings as the corresponding abutment moves toward said stop to thereby rotate said stop.

Claim 9

The apparatus of claim 7, wherein the outer edge bordering each opening is beveled and each indexing pin is provided with an inclined surface adapted to engage said beveled surface to rotate said stop.

Claim 10

A honing machine comprising a supporting structure, a pair of rotatable honing wheels, a carriage to support each honing wheel, means for mounting the carriages for movement whereby the honing wheels can be moved laterally between an inner honing position and an outer dressing position, means for moving the honing wheels between the honing position and the dressing position, dressing means for dressing the outer surface of the honing wheels when in the dressing position, a stop connected to the supporting structure and adjustably mounted for movement with respect to said supporting structure, a pair of abutments connected to one of said carriages with one of said abutments disposed to engage a face of the stop when the honing wheels are moved toward the dressing position and the other of said abutments disposed to engage a second face of the stop as the honing wheels are moved toward the honing position, each of said faces having a series of circularly spaced holes with the outer edge of each hole being beveled, and an indexing pin operably connected to each abutment, each indexing pin facing the corresponding face of the stop and adapted to engage the beveled edge of a hole of the stop as said abutment is moved toward the stop to thereby rotate the stop through a predetermined arc and thereby adjust the position of the stop with respect to the supporting structure, adjustment of the position of the stop acting to automatically adjust the dressing position and the honing position of the wheels.

Claim 11

A honing machine comprising a supporting structure, a pair of rotatable honing wheels, a carriage to support each honing wheel, means for mounting the carriages for movement whereby the honing wheels can be moved laterally between an inner honing position and an outer dressing position, means for moving the honing wheels between the honing position and the dressing position, dressing means for dressing the outer surface of the honing wheels when in the dressing position, a stop connected to the supporting structure and adjustably mounted for movement with respect to said supporting structure, a pair of abutments connected to one of said carriages with one of said abutments disposed to engage a face of the stop when the honing wheels are moved toward the dressing position and the other of said abutments disposed to engage a second face of the stop as the honing wheels are moved toward the honing position, each of said faces having a series of circularly spaced holes with the outer edge of each hole being beveled, and an indexing pin operably connected to each abutment, each indexing pin facing the corresponding face of the stop and adapted to engage the beveled edge of a hole of the stop as said abutment is moved toward the stop to thereby rotate the stop through a predetermined arc and thereby adjust the position of the stop with respect to the supporting structure, adjustment of the position of the stop acting to automatically adjust the dressing position and the honing position of the wheels.

Claim 12

The apparatus of claim 9, wherein each pin is provided with an inclined surface adapted to engage the beveled edge.

Claim 13

The apparatus of claim 9, wherein said pins are angularly offset.

Claim 14

The apparatus of claim 9, wherein the beveled edge of each hole is in contiguous relation with the beveled edges of adjacent holes.

Claim 15

The apparatus of claim 9, wherein the stop is mounted on a rod that is threadedly connected to the supporting structure.

Claim 16

The apparatus of claim 9, wherein the dressing means comprises a supporting member, a pair of dressing members, and means for moving the support member in a path of travel generally parallel to the axes of the honing wheels, each of said dressing members disposed to ride across the surface of one of said honing wheels to dress the same as the support member is moved in said path of travel.

Claim 17

The apparatus of claim 14, wherein each dressing member comprises a diamond encrusted dressing wheel, and said dressing means includes means for adjustably mounting each dressing wheel with respect to the supporting member.

Claim 20

The apparatus of claim 16, wherein the axes of said driven shafts are disposed normal to the axis of said drive shaft.

Claim 21

The apparatus of claim 17, wherein said connecting members are cog belts, said belts being twisted in opposite directions.

Claim 22

The apparatus of claim 18, and including a platform pivotally connected to the supporting structure, said prime mover and said drive shaft being mounted on said platform, and means for pivoting said platform with respect to the supporting structure to adjust the tension on said cog belts.
