Workpiece handling mechanism of a C-N-C lathe machine

A workpiece handling mechanism for a computer numerical control lathe machine, said lathe machine including a machine body which has a first motor and a main shaft mounted thereon, a hydraulically operated chuck provided at one end of said main shaft for holding a workpiece, a second motor and a first screw shaft mounted on said machine body parallel to said main shaft, said first screw shaft being driven by said second motor, a first carriage mounted on said machine body and moved by said first screw shaft towards and away from said hydraulic chuck, a second carriage mounted on said first carriage, said second carriage including a third motor, a cutting device being mounted on said second carriage for cutting the workpiece, a second screw shaft mounted on said second carriage and driven by said third motor to move said cutting device forward and backward in a direction perpendicular to said first screw shaft, a hydraulic control system for controlling the operations of said hydraulic operated chuck and said cutting device, an electric control system including a programmable control panel having a display member and, said control panel receiving a plurality of pre-fed instructions to permit automatic control of the operation of said lathe machine, said workpiece handling mechanism comprising:

• a workpiece carrying arm mounted on said second carriage;
• and
• a workpiece support spaced from said machine body and adjacent to said workpiece carrying arm, said workpiece support having a rotary disk for holding a plurality of workpieces;
• wherein said workpiece is automatically removed from said rotary disk of said workpiece support by said workpiece carrying arm and placed into said chuck, said workpiece is automatically cut by said cutting device while being held in said chuck, and, after being cut, said workpiece is automatically discharged from said chuck and placed into said workpiece support by said workpiece carrying arm.
