Abstract
A centerless grinding fixture for grinding multi-diamtter forms that do not lend themselves to be ground on a conventional centerless grinder. An example of such a part will be shown in which all surfaces,including the sides,may be ground without removing the workpiece from the grinding fixture.
Claims6
A fixture for a centerless grinding machine comprising a base, a regulating wheel assembly for a particular piece of work mounted on said base, said regulating wheel assembly formed from at least two sections secured together in spaced relationship to each other, a support shaft, said sections of the regulating wheel assembly removably mounted on said support shaft, aligned drive shafts mounted on said base, means for removably attaching said support shaft to said drive shafts so the drive shafts and support shafts are in linear alignment whereby the entire regulating assembly can be lifted off the base and stored for future use.
A fixture for a centerless grinding machine comprising a casting, said casting having upstanding side walls, said side walls having facing surfaces, oppositely extending hubs formed in the side walls, sets of bearings mounted in the hubs in such a way that the center line of the bearings in the side walls are in alignment, drive shafts mounted in each side wall with the axes of each drive shaft aligned with the center line of the bearings, positioning supports mounted on the facing surfaces of each side wall, support clamps fixedly mounted each side wall and positioned by said positioning supports, a support shaft for a regulating wheel, clamping means for each end of the support shaft for releasably clamping the support shaft on the shaft supports to the drive shafts so that the axis of the support shaft is in alignment with the axes of the drive shafts.
In a centerless grinding machine, a casting, said casting having upstanding side walls, a bearing support hub on each side wall, sets of bearings for supporting drive shafts mounted in said hubs in such a way that the center line of the bearings in the side walls are in alignment, drive shafts mounted in said hubs and supported by said bearings with the axes of each drive shaft aligned with the center line of the bearings, positioning supports mounted on the facing surfaces of each side wall, shaft supports fixedly mounted each side wall and positioned by said positioning supports, a support shaft for a regulating wheel, clamping means for each end of the support shaft for releasably clamping the support shaft on the shaft supports to the drive shafts so that the axis of the support shaft is in alignment with the drive shafts.
A fixture for a centerless grinding machine comprising a casting, said casting having upstanding side walls, said side walls having facing surfaces, a bearing supporting hub on each side wall, sets of bearings for supporting drive shafts mounted in said hubs in such a way that the center line of the bearings in the side walls are in alignment, drive shafts mounted in said hubs supported by said bearings with the axes of each drive shaft aligned with the center line of the bearings, positioning supports mounted on the facing surfaces of each side wall, clamping means fixedly mounted each side wall and positioned by said positioning supports, a regulating wheel assembly ,a support shaft for said regulating wheel assembly, clamping means for each end of the support shaft for releasably clamping the support shaft on the shaft supports to the drive shafts so that the axis of the support shaft is in alignment with the drive shafts, said regulating wheel assembly having two sections spaced apart by means of a spacer, a secondary tube threaded at each end concentric with and extending through said regulating wheel sections, threaded washers threaded onto the threaded portions of the secondary tube that extend through the regulating wheel sections so that when the washers are tightened, the regulating wheel sections are tied together, said support shaft removably positioned inside said secondary tube, an additional washer threaded onto the tube to lock the secondary tube to the support shaft.
