Full closed-loop numerical control gear shaper for large-scale hydraulic main drive cutting

Abstract

The invention relates to a full closed-loop numerical control gear shaper for large-scale hydraulic main drive cutting, comprising a rotary table, a shaper body assembly, an intermediate shaper body assembly, a stand column, a cutter relieving mechanism, a cutter rest mechanism, a numerical control system, a hydraulic system, a lubricating system and a cooling chip removing system. Serve motors are arranged on both sides of the rotary table and are connected with a worm gear motion pair through a shaft coupler to form a dual-driving mechanism of the rotary table; a cutter shaft of the cutter rest mechanism is driven by a hydraulic cylinder to do reciprocating motion; a motor base of the cutter rest mechanism is provided with a servo motor; and the cutter relieving mechanism is provided with camshafts of a conjugate dual cams to connect and drive the servo motor. The invention has the advantages that the gear shaper adopts the servo hydraulic cylinder to drive to provide reciprocating motion of the cutter shaft, adopts a torque motor to provide the rotary motion of the cutter shaft and adopts the servo motor to drive the cutter relieving mechanism to meet the processing requirement of large-scale precise gears; the rotary table bears heavy load and has high operation stability; the processing range, the stroke length and the cutting force are enlarged; the processing precision is high; and the processing flexibility adaptability is strong.

Description

technical field [0001] The technical field of the numerical control gear shaping machine of the present invention, in particular relates to a large-scale hydraulic main drive cutting full-closed-loop numerical control gear shaping machine. Background technique [0002] Large-scale gears are key components of large-scale wind power generation, large-scale forging equipment, large-scale metallurgical equipment, and large-scale ship transmissions. Large-scale CNC gear shaping machines are their indispensable working machines. At present, my country's large-scale precision multi-axis CNC gear shaping machines are still blank. [0003] CNC gear shaping machines generally have control axes such as the rotary motion of the rotary table, the reciprocating main drive of the cutter shaft, the rotary motion of the cutter shaft, the radial feed motion, the tool letting motion and the oblique tool letting movement. At present, the driving method of the rotary table of large-scale CNC gea...
