Gear turning machine

Abstract

The invention discloses a gear turning machine. The gear turning machine is characterized in that a six-axis four-linkage machining mode is adopted, an X axis formed by a machine tool bed and other parts is responsible for radial cutter depth feeding, a Z axis formed by a machine tool stand column and other parts is responsible for axial cutting feeding, a C axis is responsible for workpiece rotation, a B axis is responsible for cutter rotation, hydraulic pressure is provided for workpiece clamping and cooling through a hydraulic station connected through an oil pipe, an A axis formed by an Aaxis dragging plate, a stand column dragging plate and other parts is responsible for adjustment of the angle of a cutter, and a Y axis formed by the A axis dragging plate and other parts is responsible for adjustment of the center of the cutter. According to the gear turning machine, gear machining is achieved through simultaneous action of gear shaping and gear hobbing, and the problems of low efficiency and low precision of traditional gear machining are solved; high-efficiency and high-precision machining is achieved; the efficiency of machining a common gear is 4 times or more that of a traditional machining process, and the precision grade can reach grade 6; and cutter angle adjustment adopts direct connection, and the positioning precision is high; and the C axis adopts a direct drive motor, then the power transmission links are few, the transmission rigidity is high, the efficiency is high, and the positioning precision is better.
