Abstract
Abstract A duplicating device for grinding or milling machines in which a copying roller is turnably mounted on the frame of the machine and in which a workpiece holder adapted to carry a workpiece to be machined carries a template having a contour to which the workpiece is to be machined. The workpiece holder is mounted on the machine frame turnable about an axis parallel to that of the copying roller and movable transverse thereto so that the contour of the template is held in engagement with the copying roller. The workpiece holder includes fine adjusting means for adjusting the position of a workpiece carried thereby and that of the template relative to each other.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
174 words
In a duplicating device for machines with a rotary material removing tool, a combination comprising support means; a copying roller rotatably mounted on said support means about a predetermined axis; a workpiece holder means for carrying a workpiece; a template having a contour to which a workpiece carried by said workpiece holder means is to be machined; means mounting said workpiece holder means on said support means turnable about an axis parallel to said predetermined axis and movable transverse thereto for holding said copying roller in engagement with said contour; means for rotating said workpiece holder means about its axis; means on said workpiece holder means for finely adjusting the position of a workpiece carried by said workpiece holder means and the position of said template relative to each other; and tool means including a rotary tool spindle, a material removing tool fixed to said spindle for rotation therewith, and a tool slide mounted on said support means movable in axial direction of said tool spindle toward and away from said workpiece holder means.
Claim 2
Dependent Claim
174 words
In a duplicating device for machines with a rotary material removing tool, a combination comprising support means; a copying roller rotatably mounted on said support means about a predetermined axis; a workpiece holder means for carrying a workpiece; a template having a contour to which a workpiece carried by said workpiece holder means is to be machined; means mounting said workpiece holder means on said support means turnable about an axis parallel to said predetermined axis and movable transverse thereto for holding said copying roller in engagement with said contour; means for rotating said workpiece holder means about its axis; means on said workpiece holder means for finely adjusting the position of a workpiece carried by said workpiece holder means and the position of said template relative to each other; and tool means including a rotary tool spindle, a material removing tool fixed to said spindle for rotation therewith, and a tool slide mounted on said support means movable in axial direction of said tool spindle toward and away from said workpiece holder means.
Claim 3
Dependent Claim
37 words
A combination as defined in claim 1, wherein said template is fixedly mounted on said workpiece holder and wherein said fine adjustment means serves to adjust the position of a workpiece relative to that of said template.
Claim 4
Dependent Claim
61 words
A combination as defined in claim 2, wherein said fine adjusting means comprises means for adjusting the position of a workpiece by turning the latter about an axis parallel with that about which said workpiece holder is turned and for moving said workpiece in two directions normal to each other and extending in radial direction with respect to the last-mentioned axis.
Claim 5
Dependent Claim
97 words
A combination as defined in claim 3, wherein said workpiece holder means comprises a main body having an axis and being mounted on said support means turnable about said axis and movable transverse thereto, said fine adjustment means comprising a first carrier member for carrying a workpiece, a second carrier member carrying said first carrier member turnable about an axis parallel with said axis of rotation of said main body, means mounting said second carrier member on said main body adjustable in two directions normal to each other and extending radially with respect to the last-mentioned axis.
Claim 6
Dependent Claim
130 words
a combination as defined in claim 4, wherein said main body has a pair of end faces normal to its axis, said template being fixed to one of said end faces and including at least two stop members projecting from the other of said end faces and each having at least one abutment face normal to said other end face, said second carrier member having side faces parallel to said abutment faces, a plurality of plate-shaped spacer members of different thickness selectively insertable between said side faces and said abutment faces, and means on said main body for pressing said second carrier member towards said stop members so as to hold said side faces in engagement with the respective spacer members and the latter in engagement with said abutment faces.
Claim 7
Dependent Claim
71 words
A combination as defined in claim 4, wherein said first carrier member comprises an annular member having an outer peripheral surface of circular outline, at least three guide rollers on said second carrier member engaging said outer peripheral surface and mounting said annular member turnable about its axis, and cooperating means on said annular member and said second carrier member for fixedly holding said annular member in an adjusted turned position.
Claim 8
Dependent Claim
38 words
A combination as defined in claim 4, and including means for fixedly holding said firsT carrier member in an adjusted turned position on said second carrier member and the latter in an adjusted position on said main body.
Claim 9
Dependent Claim
33 words
A combination as defined in claim 4, and including holding means for holding a workpiece in exact position on said first carrier member and said template in exact position on said main body.
Claim 10
Dependent Claim
24 words
A combination as defined in claim 8, wherein said holding means comprise dowel pins respectively insertable into bores of said workpiece and said template.
Claim 11
Dependent Claim
58 words
A combination as defined in claim 9, and including a pair of set-up templates having reference edges and being provided with bores for receiving said dowel pins so that said set-up templates may be placed on said dowel pins to respectively replace the template used during the machining operation and the workpiece during set-up of the duplicating device.
