Abstract

The machine disclosed includes apparatus for splining thin-walled sleeves of power transmission members that are mounted on a toothed mandrel between a pair of toothed dies by an automatic loader which also removes the members from the mandrel after the splining. Loading and unloading members of the loader are moved axially along the axis of mandrel rotation by associated actuating cylinders to move members to be splined from an indexer onto the mandrel and to move the members after splining from the mandrel back to the indexer. Clamping surfaces on the end of the mandrel and a rotatable clamp of the loading member position the sleeve of a member being splined over the mandrel teeth. The unloading member is received within a central opening of the mandrel and has an annular centering surface that properly locates the member being splined. In one preferred embodiment, the toothed dies comprise straight racks that are slidably movable on opposite sides of the mandrel with one of the racks fixed to a timing rack which meshes with a timing gear on the spindle to coordinate the mandrel rotation with rack movement. In another preferred embodiment, the toothed forming faces of the dies are curved.
