Forming and milling process of automotive differential clutch engagement sleeve

Abstract

The invention discloses a forming and milling process of an automotive differential clutch engagement sleeve. The process includes the steps: 1) clamping a workpice, mounting an engagement sleeve workpiece on an index plate, and adjusting an angle alpha between an engagement surface of the engagement sleeve workpiece and a milling machine workbench through the index plate, wherein the angle alpha is an included angle between a cutting edge I of a backoff milling cutter and an axis of the backoff milling cutter; 2) setting the cutter to enable the backoff milling cutter to be positioned in a radial direction of the engagement sleeve workpiece in a feed direction parallel to a milling machine workbench direction; 3) performing primary milling by utilizing the backoff milling cutter to mill a side tooth crest, a side tooth flank and a side tooth socket on the engagement sleeve workpiece; 4) rotating the engagement sleeve workpiece by 180 degrees; 5) performing secondary milling by utilizing the backoff milling cutter to mill another side tooth crest, another side tooth flank and another side tooth socket on the engagement sleeve workpiece; and 6) rotating the engagement sleeve workpiece with a rotating angle equal to a mechanical angle of between two adjacent engagement teeth, and repeating the step 3) to the step 5) until all engagement teeth are machined.

Description

technical field [0001] The invention belongs to the technical field of milling, in particular to a forming milling process for an engagement sleeve of an automobile differential clutch. Background technique [0002] Such as figure 1 As shown, it is a structural schematic diagram of the meshing sleeve of the automobile differential clutch, and the meshing surface of the meshing sleeve 1 of the automobile differential clutch is uniformly arranged with meshing teeth 2 in a ring. Such as image 3 As shown, the shape and structure of the meshing teeth 2 are relatively complex. The two ends of the tooth tops of the meshing teeth 2 are provided with a tooth top bevel angle θ=7°, and the bottom width of the meshing tooth groove between two adjacent meshing teeth 2 Wider than the width of the top, that is, the inclination angle of the tooth side is δ=1°38'±3', and there is a circular arc transition between the tooth side and the groove bottom of the meshing tooth groove. Because t...
