AI Technical Summary

Technical Problem

In the machining of internal gear rings, existing CNC gear shaping machines suffer from insufficient cutting fluid flow rate, leading to chip retention, which causes the gear shaping cutter to collide with and damage the chips, resulting in surface quality defects on the workpiece.

Method used

A CNC gear shaping machine was designed. By setting a chip removal component on the machining base and connecting the power output end of the main cutting component to the cleaning unit, a pulse airflow synchronized with the cutting action is generated, which forces the waste chips to be blown away and discharged along the inclined surface, thus avoiding the gear shaping cutter from hitting the waste chips.

Benefits of technology

This effectively prevents the gear shaper from chipping due to chip impact, thus improving the machining accuracy of the internal gear ring and the tool life.

Abstract

This invention discloses a CNC gear shaping machine, belonging to the technical field of gear shaping machines. It includes a machine tool, a base assembly, a main cutting assembly, a fixture assembly, and a chip removal assembly. The rotary table surface of the base assembly has a ramp. The main cutting assembly is positioned above the base assembly and drives the gear shaping cutter to perform reciprocating cutting motion in the vertical direction. The fixture assembly is fixed on the rotary table. The chip removal assembly is mounted on the machining base and includes a linkage unit and a cleaning unit. The linkage unit connects the power output end of the main cutting assembly and the cleaning unit, converting the reciprocating cutting power of the main cutting assembly into the pumping power of the cleaning unit. The output end of the cleaning unit extends to the machining area of ​​the gear shaping cutter. This invention utilizes a linkage structure to synchronously generate pulsed airflow during the cutting return stroke, which, combined with the ramp surface, forcibly blows away waste chips, effectively solving the problems of tool chipping and workpiece surface damage caused by waste chip accumulation in internal gear machining.
