This invention relates to an apparatus for mounting lathe chucks and faceplates on a lathe. The installation and removal of chucks and face plates from lathes has presented a difficult problem, particularly in the larger size lathes wherein the chucks and face plates are relatively heavy and cannot be easily handled by one man. In installing and removing the chucks or the like, it is necessary to support the chuck in proper alignment with the lathe spindle and then rotate either the chuck or the spindle to thread the former onto the spindle. If the chuck is not properly supported in alignment with the spindle, the chuck may bind on the threads of the spindle as the chuck is screwed on or off the spindle and thus damage the threads. Moreover, the chuck may fall, if not properly supported, thereby damaging the chuck, lathe bed, or both. An important object of this invention is to provide an improved support fixture for handling chucks or face plates and adapted for mounting on the cross slide of a lathe for movement therewith longitudinally and laterally of the lathe spindle. Another object of this invention is to provide a lathe chuck mounting fixture arranged for mounting on the lathe cross slide without any modification in the construction of the lathe. A more particular object of this invention is to provide a fixture for mounting lathe chucks and the like and arranged to be detachably clamped to the cross slide by the tool clamping mechanism on the tool holder, to thereby enable rapid attachment and detachment of the fixture from the lathe. A further object of this invention is to provide a fixture for mounting lathe chucks and the like arranged to handle all sizes of chucks and face plates which are used oh the lathe and which has provision for counteracting the overbalance on the cross slide, due to the weight of the chuck when the latter is carried by the fixture. |
