The invention discloses a
numerical control gear shaping machine based on double-drive synchronous compensation, and belongs to the technical field of
gear shaping machines. Comprising a lathe
bed, a stand column vertically and fixedly connected to one side of the top of the lathe
bed, a tool rest slidably connected to one side of the stand column, a slotting cutter detachably installed at the bottom of the tool rest, a radial sliding table slidably arranged on the other side of the top of the lathe
bed and a sliding plate slidably arranged on the top of the radial sliding table. The
workbench is rotationally arranged at the top of the sliding plate; and the rotating motor drives the
workbench to rotate. The radial feeding
system composed of the
servo motor, the
ball screw and the sliding block is symmetrically arranged at the top of the radial sliding table, driving force can be applied to a
machining part in a balanced mode from the two sides,
radial stress generated in the scene of large-load
machining or large-
diameter workpiece
machining can be effectively offset, the deflection deformation amount of the
ball screw is greatly reduced, and the machining precision is improved. Radial positioning precision fluctuation caused by lead screw deformation is avoided, the precision stability of key parameters such as the tooth
pitch and the tooth shape in the gear
machining process is finally ensured, and the precision
gear manufacturing requirement is met.
