A grinding machine having a frame that supports an overhead grinder having a generally horizontal grinding wheel. Longitudinal beam assemblies are supported by the frame. The upper edges of the beam assemblies define inverted V guide tracks on which the wheels of a truck are supported. The truck has an upper deck that supports an object to be ground. The beam assemblies are supported from the frame by universal mounted adjustable legs. Cam and cam follower connections between the beam assemblies and the frame restrict lateral movements and maintain the alignment of the beam assemblies as they are vertically adjusted by the adjustment of the adjustable legs. The adjustment of the beam assemblies allows the tracks to be set parallel to one another defining an inclined plane. The truck has wheels on adjustable bearings so the deck will remain parallel to the grinding surface of the grinding wheel to be ground.
A grinding machine comprising a stationary base frame and two relatively movable members, a first member comprising a grinder having a grinding wheel with a grinding surface on the grinding wheel, means for supporting the grinding wheel from the base frame with the grinding surface in predetermined orientation relative to the base frame, a second member comprising a deck for supporting an object to be ground, means for supporting the deck from the base frame, wherein the means for supporting the deck comprises a plurality of supporting means having movable elements allowing movement of the second member relative to the first member to establish a grinding pass between the grinding surface and the object, said means for supporting the deck from the base frame comprises two beams assemblies supported from the base frame and having tracks thereon, wherein the plurality of supporting means comprise wheels which are supported on the tracks, means for adjusting the relative angular orientation of the grinding surface and the deck to maintain them in planes that are parallel to one another, a means for adjusting the beam assemblies relative to the base frame to locate the tracks parallel to one another and inclined relative to said planes, a means for adjusting the wheels relative to the second member so that the planes are parallel in spite of the inclination of the tracks, and means for decreasing the distance between the planes in proportion to wear on the grinding surface during movement of the second member relative to the first member in a grinding pass between the grinding surface and the object.
A grinding machine comprising a base frame, a pair of beams, means for supporting the beams for universal movement relative to the base frame and means for restricting such movement, a pair of elongated tracks supported by the upper sides of the beams, means for adjusting the supporting means to locate the tracks parallel to one another, a grinding wheel assembly supported by the base frame spaced above the tracks and having a downwardly depending grinding means, a truck having a deck for supporting a part to be ground, a plurality of wheels in parallel rows on the truck for riding on the tracks to support the truck with the deck positioned below the grinding wheel.
A grinding machine comprising a frame, a grinding wheel assembly, means for supporting the grinding wheel assembly from the frame, the grinding wheel assembly having a grinding wheel for grinding in a plane, a pair of beams supported for universal movement from the frame, a pair of tracks supported by the beams, means for adjusting the beams relative to the frame so that the tracks define a plane inclined to the grinding plane, truck for supporting a part to be ground, and a plurality of vertically adjustable wheels on the truck engageable with the tracks for supporting the truck thereon, and means for adjusting the wheels.
A grinding machine comprising a frame, a truck movably supported by the frame, a grinder supported by the frame and having a grinding wheel spaced above the truck for grinding contact with an object resting on the truck, the frame having means defining bearing surfaces on which the truck is movably supported, means for adjusting the plane of said bearing surface means, and means to restrict lateral movements of the bearing surface means during operation of said adjusting means.
