Example Embodiment

[0024] The spline consistency requirements data of BE second axis 3rd and 4th gears are as follows figure 1 Shown. The P1-P distance of the 3rd and 4th gears is 58.32, and the spline consistency deviation requirement is ≤0.05, which is the special requirement of the BE second axis 3rd and 4th gears.

[0025] BE two-axis cloth knife figure 2 , Figure 5 Shown. It adopts one Italian MS5 rolling machine with five-axis CNC. BE second-axis 5-speed rolling wheels, 3-4-speed rolling wheels, 1 / 2-speed rolling wheels, and thread rolling wheels are sequentially distributed in BE second-axis station 3, second-axis station 2, and second-axis station 1, Two-axis station 4 on four stations. The processing method of the 3-4 gear rolling wheel is: 1. Process the rolling wheel and add a circle; 2. Assemble the two rolling wheels to process the spline; 3. Disassemble the assembled rolling wheel; 4 , Padded between the two rolling wheels, and adjust the angle of the two rolling wheels; (the straigh...

Abstract

The invention relates to a technology for rolling various multi-station spline threaded shafts, belonging to the technical field of automobile gear box spline threaded shaft processing technology. The technology mainly solves the problem that the existing technology only can process BE uniaxial or biaxial spline and thread by three rolling devices and a gear rolling device. The technology is mainly characterized in that a rolling machine with five numeric control shafts is adopted; a principal axis is provided with four stations sequentially and is correspondingly provided with rolling wheels or screw rolling wheels, wherein, 3-4 rolling wheels are formed by two same rolling wheels which are alternatively fixed along the same straightness; a BE biaxial or uniaxial workpiece is respectively moved to the position 1, the position 2, the position 3 and the position 4 to be processed into a corresponding spline and thread; and the BE biaxial work piece after processing is returned to an initial position. The invention has the characteristics of using one device to process the BE uniaxial or biaxial spline and thread, meeting the requirement of processing quality and least invest cost. The technology is mainly used for processing the BE uniaxial or biaxial spline and thread.

Description

technical field [0001] The invention belongs to the technical field of processing technology for spline threaded shafts of automobile gearboxes. Specifically, it relates to a rolling processing technology of a BE gearbox spline thread first shaft (hereinafter referred to as BE first shaft) and a spline thread second shaft (hereinafter referred to as BE second shaft). Background technique [0002] There are clutch splines, 3 / 4 splines, 5 splines, 3 splines and 1 thread on the BE first shaft, and 5 splines, 4 splines, 3 splines, 1 / 2 splines on the BE second shaft. The gear spline has 4 sections of splines and 1 section of thread, and BE 1st and 2nd shafts have a total of 7 sections of splines and 2 sections of thread. PSA Group uses 3 sets of rolling equipment to process the splines and threads on the first axis of BE, and uses 2 sets of rolling equipment and 1 set of gear rolling equipment to process the splines and threads of the second axis of BE. Among them, the gear roll...
