Abstract
An apparatus for adjusting the regulating wheel pivot in a centerless grinder machine when used for thrufeed grinding, comprising a means for tilting the axis of the regulating wheel to provide a thrufeed vector feed, and further comprising a means for elevating the tilt axis to accommodate a range of workpiece diameters without redressing the shape of the regulating wheel.
Claims3
In a centerless grinding machine of the type having a base;
- a grinding wheelhead;
- a regulating wheelhead adapted to drive and support a workpiece in contact with the grinding wheel, and;
- a slide supporting one of the grinding and regulating wheelheads and moveable on said base along a feed axis for relative movement of the wheelheads in a grinding operation, wherein said regulating wheelhead is adapted to pivot about a joint so as to pivot said regulating wheelhead in a plane transverse to said feed axis;
- an improved pivot adjusting device comprising:
- means to move said pivot joint along said transverse plane.

In a centerless grinding machine of the type having a base;
- a grinding wheelhead fixed to said base;
- a slide moveable on said base along a feed axis relative to said grinding wheelhead;
- a regulating wheelhead carried on said slide and adapted to drive and support a workpiece wherein said regulating wheelhead is adapted to pivot about a joint so as to pivot said regulating wheelhead relative to said slide in a plane transverse to said feed axis and further wherein the regulating wheel is directly opposite the grinding wheel in the direction of the feed axis;
- an improved device to permit adjustment of said pivot joint along said transverse plane comprising:
- a block, adapted to carry said pivot joint, wherein said block is slidably maintained in a track in said slide;
- and
- a screw and nut system adapted to move said block in said track.
