Abstract
The invention discloses a method for manufacturing an automotive bevel gear shaft. The method is performed according to the following sequence: firstly, manufacturing a workpiece blank by means of die forging, machining central holes in the both ends of the workpiece, positioning the workpiece by virtue of the central holes, then turning a tooth blank section according to design dimensions; secondly, still positioning by virtue of the central holes of the workpiece, implementing tooth forming by means of cutting, and performing conventional heat treatment on the workpiece which finishes tooth-cutting machining; finally, positioning and installing a tooth die in a clamp and the bevel gear of the workpiece, and then performing finish turning until each shaft neck on the shaft section of a cantilever beam shaft to achieve design dimensions. The method disclosed by the invention is short in process route, high in production efficiency, capable of avoiding external damages and internal stress generated on the surface of the workpiece, and beneficial to improve the inherent quality of the workpiece. Most of all, each shaft neck on the shaft section of the workpiece is positioned by teeth and subjected to finish turning, and due to the positioning structure, the superposition of a machining positioning reference and an installation reference is realized, thus greatly improving the coaxial accuracy of the teeth and the shaft necks, and contributing to improve the transmission quality of the workpiece after being installed.
Description
Technical field
The present invention relates to a kind of axle part manufacture method, specifically, the present invention relates to a kind of automobile-used bevel gear shaft manufacture method.
Background technology
Bevel gear shaft is the main driving member in automobile, tractor and driving bridge for engineering machinery, and its architectural feature is that one end of axle is provided with integrated bevel gear, and shaft part directly affects transmission quality with the coaxial index of bevel gear.Due to the particularity of bevel gear shaft structure, bevel gear and axle journal section must separating machine processing.So the process route of prior art is longer, operation is more, and concrete technology route is: rough forging → Vehicle Processing tooth billet → cutting processing → bulk heat treatmet → alignment → flaw detection → finish turning axle journal.It is positioning datum that cutting operation in above-mentioned technique be take the preset centre bore in workpiece two ends conventionally, and this positioning datum is consistent with design basis, can reach expection cutting quality completely.Workpiece after cutting axle journal section when implementing bulk heat treatmet inevitably occurs bending and deformation, although the alignment process arranging afterwards can reduce the flexibility of shaft part, can not eliminate distortion completely.Through heat treated workpiece combination property, must increase, increase thus the difficulty of alignment, the alignment of exerting pressure easily produces impression, micro-crack and internal stress etc. problem on shaft part.For fear of defective products, proceed to subsequent production, be provided with flaw detection operation after alignment process, the workpiece being up to the standards just can forward finish turning axle journal operation to.It is positioning datum that finish turning axle journal still be take the preset centre bore in workpiece two ends,, the preset centre bore in workpiece two ends, in the position of bulk heat treatmet and alignment process front and back, trace occurs to be changed, cutting processing and the position error of finish turning axle journal, consequently bevel gear and axle journal disalignment afterwards before causing.The installation of bevel gear shaft in drive axle is to take axle journal as positioning datum, is not the preset centre bores in workpiece two ends, so bevel gear and axle journal disalignment must reduce transmission quality.
Summary of the invention
The present invention, mainly for the not good enough problem of bevel gear shaft quality of prior art processing, proposes a kind of automobile-used bevel gear shaft manufacture method, and the method operation is few, do not produce internal stress, easily machined is accurately located, is convenient in realization.
The present invention is achieved through the following technical solutions technical goal.
Automobile-used bevel gear shaft manufacture method, its improvements are to do in the following order machined:
A, rough forging
Adopt die forging method to manufacture workpiece blank;
B, Vehicle Processing tooth billet
First process the centre bore at workpiece two ends, with centre bore positioning workpieces, then by design size Vehicle Processing tooth billet;
C, cutting processing
Still, with workpiece two ends centre bore location, adopt cutting way to implement tooth portion and be shaped;
D, bulk heat treatmet
The workpiece that completes cutting processing is done to conventional heat treatment;
E, finish turning axle journal
With the tooth mould in fixture, coordinate with the cone tooth of workpiece and make location and installation and clamp, then finish turning is each axle journal on cantilever Beam shaft part to design size.
The present invention compared with prior art, has following good effect:
1, save alignment and flaw detection two procedures, significantly improve work efficiency, save production cost;
2, not alignment of workpiece, avoids producing wound and internal stress, is conducive to improve workpiece inherent quality;
3, with each axle journal on tooth portion positioning accurate turner part shaft part, processing positioning datum and reference for installation overlap, and greatly improve the coaxial precision of tooth portion and axle journal, are conducive to improve the transmission quality after workpiece installation.
Accompanying drawing explanation
Fig. 1 is the structural representation of automobile-used bevel gear shaft described in the present invention.
The specific embodiment
Below in conjunction with embodiment, the invention will be further described.
The present embodiment is the bevel gear shaft in motor bus drive axle automobile differential, wherein bevel gear major parameter: tooth number Z=9, big end surface modulus m
s=12, tip diameter D
e=137mm, bevel gear axial length L=294mm, axle journal diameter d=65mm.Because the bevel gear shaft size in automobile-used drive axle is relatively little, the automobile-used bevel gear shaft manufacture method of different size is identical, and it carries out in the following order:
A, rough forging
Adopt die forging method to manufacture workpiece blank;
B, Vehicle Processing tooth billet
First process the centre bore at workpiece two ends, with centre bore positioning workpieces, then by design size Vehicle Processing tooth billet;
C, cutting processing
Still, with workpiece two ends centre bore location, adopt cutting way to implement tooth portion and be shaped;
D, bulk heat treatmet
The workpiece that completes cutting processing is done to conventional heat treatment;
E, finish turning axle journal
Press the relevant cone of embodiment toothing parameter and make tooth mould, tooth mould is arranged in fixture, coordinates do also clamping of location and installation with the tooth mould in fixture with the cone tooth of workpiece, and then finish turning is each axle journal on cantilever beam shaft part to design size.
The bevel gear shaft that adopts said method to process, saves alignment and flaw detection two procedures than prior art, significantly improves work efficiency, saves production cost.Also avoid, when implementing alignment, surface of the work is produced to wound and internal stress, be conducive to improve the inherent quality of workpiece simultaneously.The benefit of maximum of the present invention be workpiece with each axle journal in tooth portion positioning accurate axletree section, this kind of location structure accomplished to process positioning datum and overlapped with reference for installation, greatly improves the coaxial precision of tooth portion and axle journal, is conducive to improve the transmission quality after workpiece is installed.
