Abstract
Rod stock pieces are successively fed in a path to a work station of a multiple spindle automatic turning machine such as a lathe. A slide member supports a trailing rod stock piece and is mounted on the machine for movement towards and away from the work station. The slide member is coupled with a drive of the turning machine to thereby move the slide member together with the rod stock piece supported therewith through a stroke of predetermined length. The length of the stroke of the slide member is adjusted in dependence upon the length of the leading rod stock piece located at the work station.
Claims9
An arrangement for advancing rod stock pieces in a turning machine of the type having a drive and a work station at which successive workpiece portions of the rod stock pieces are to be treated, comprising means for successively feeding a rod stock piece to the work station, including a slide member for supporting a rod stock piece and being mounted on the machine for movement towards and away from the work station;
- means for coupling said slide member with the drive to thereby move said slide member together with the rod stock piece supported therewith through a stroke of predetermined length, including a slide carriage mounted on the machine for movement towards and away from the work station, means on said slide carriage and on said slide member for interconnecting said slide carriage and said slide member to thereby permit concomitant movement on said slide carriage and said slide member, and a control unit having a piston component and a cylinder component, one of said components being connected with said slide carriage and the other of said components being connected with the drive;
- and means for adjusting the length of the stroke of said slide member in dependence upon the length of the rod stock piece at the work station, including means for displacing one of said components relative to the other of said components to thereby move said slide carriage together with said slide member through a stroke of length greater than said predetermined stroke length.
An arrangement for advancing rod stock pieces in a turning machine of the type having a drive and a work station at which successive workpiece portions of the rod stock pieces are to be treated, comprising means for successively feeding a rod stock piece to the work station, including a slide member for supporting a rod stock piece and being mounted on the machine for movement towards and away from the work station so as to move successive workpiece portions of the rod stock piece to the work station;
- means for coupling with the drive to thereby move said slide member together with the rod stock piece supported therewith through a stroke of a predetermined length;
- and means for displacing said slide member together with said rod stock piece through an additional stroke sufficient to expel the remaining rod stock piece when the length of said rod stock piece decreases to a predetermined minimum length.
