Abstract
A honing tool slot protecting bushing is disclosed for gripping an abrasive element while mechanically isolating the abrasive element from the remainder of the honing tool. The slot liner is in the form of a bushing having four interconnected wall portions extending generally parallel to one another and including either a lip arrangement or a threaded fastener arrangement for holding the bushing fixedly within the body of the honing tool. The abrasive element is supported by the bushing and retained therein due to the frictional forces between the abrasive element and the bushing.
Claims13
In a honing tool having a generally cylindrical body portion provided with a plurality of longitudinally extending outwardly opening radial slots, an abrasive element formed entirely of abrasive material disposed in each of said slots, a like plurality of expander plates adjacent to but unconnected with the corresponding abrasive elements, carried by the body and projecting radially outwardly with the outer end portions thereof being disposed in the slots and engaging respective abrasive elements, and means for selectively urging all the expander plates and therefor also the abrasive elements simultaneously radially outwardly and into engagement with a workpiece, an improved means for mounting and retaining individual abrasive elements in their respective slots comprising a bushing supported against radial movement in the body portion within the slot and extending radially to simultaneously girdle at least a portion of the abrasive element and at least a portion of the pertaining expander plate with the abrasive element being supported for radial movement relative to the bushing and being retained therein by frictional engagement between the abrasive element and the bushing.
