Diagonal rolling cut three-axis numerical control hobbling machine

Abstract

The invention relates to a three-axis numerical control hobbling machine for realizing diagonal rolling cut by replacing a flee cutter saddle with a tangential cutter saddle, which solves the problems that in the prior art, the Y axis and the C axis of the three-axis numerical control hobbling machine cannot realize linkage and consequently normal teeth separation cannot be guaranteed. The three-axis numerical control hobbling machine comprises a machine tool body, an upright post mechanism, a rolling cutter saddle mechanism and a workbench mechanism, wherein the lifting upright post mechanism comprises a Z axis; a roller arranged in the rolling cutter saddle rotates around the roller; the workbench moves along an X axis which is vertical to the Z axis and the Y axis respectively and rotates around the C axis which is parallel to the Z axis; the roller is driven to rotate by a main motor; the Z axis is driven by a Z-axis servo motor; the rolling cutter saddle is driven by a Y-axis servo motor; the workbench is driven by a X-axis servo motor; the speed at which the rolling cutter saddle axially moves along the Z axis is equal to that at which the rolling cutter moves along the Y axis axially so as to form linkage; the output end of the upright post mechanism is provided with a first gear pair; the output end of the main motor is provided with a second gear pair; the output of the upright post mechanism is combined with that of the main motor to be connected to the workbench mechanism to drive the workbench to rotate along the C axis; the rotating speed of the Z axis is equal to that of the Y axis; and the Z axis is linked with the C axis of the workbench, so that the Y axis is connected with the C axis to form the linkage. Thus, the rotation of the C axis can get comprehension during rolling cut to avoid generating gear cutting.

Description

technical field [0001] The invention relates to a three-axis numerically controlled gear hobbing machine which uses a shifting tool holder instead of a tangential tool holder to realize diagonal hobbing. Background technique [0002] When hobbing gears, the processing method of axial feed and tangential linkage feed is called diagonal hobbing method. [0003] The tangential feed in diagonal hobbing will destroy the normal splitting motion. There are two conventional methods to ensure that the splitting motion is not destroyed: [0004] One is to use a mechanical transmission chain to connect the tangential motion of the tangential tool holder with the rotary motion of the worktable, and perform differential compensation through differential synthesis. gear module), table compensation rotation 1 / Z turn (z-gear teeth number); [0005] Second, on the four-axis CNC gear hobbing machine, use the table to rotate the C-axis to track the tangential feed Y-axis. When the Y-axis mov...
