Remanufacturing CNC Gear Hobbing Machine Based on Lathe Hardware Platform

Abstract

The invention relates to a lathe hardware platform based remanufacturing numerical control hobbing machine. The machine comprises, a lathe bed, a main shaft possessed by a lathe and driven by a three-phase asynchronous motor C, a large carriage, a small carriage, and a screw nut pair driving the large carriage, and a numerical control system, wherein a hobbing cutter assembly is positioned on the small carriage, and the small carriage is installed on the large carriage in a sliding manner and is driven by a servomotor X to realize the radial feed motion of hobbing cutters; a self-centering clamp concentric with the main shaft is fixed on the large carriage, and a workpiece is clamped by a chuck on the main shaft and the self-centering clamp; the screw nut pair is driven by a servomotor Z to drive the large carriage to move along a lathe guide rail; and the numerical control system adopts an electronic gearbox program and a differential electronic gearbox program to program, synergistically controls the motions of the three-phase asynchronous motor C, a three-phase asynchronous motor B, the servomotor X and the servomotor Z, substitutes an index change gear gearbox and a differential change gear gearbox on traditional mechanical hobbing machines, and simplifies the transmission structure.

AI Technical Summary

Problems solved by technology

[0005] The traditional gear hobbing machine is the metal cutting machine tool with the most complex transmission principle. Its complex transmission chain makes the mechanical structure very complicated, and the precision is poor, the speed is low, the wear is serious, the adjustment is difficult, and it cannot process gears with a small number of teeth (especially those with less than 4 teeth. gears), it cannot meet the requirements of high-speed and high-precision machining gears (especially the requirements of dry cutting non-metallic materials for gear hobbing machines), and the orbital travel of general traditional gear hobbing machines is not long, so it is difficult to process long gear shafts

[0006] At present, most of the gear hobbing machines used in China adopt vertical structure, which is not suitable for processing long shaft parts.
