Background technique
Waveform turbine (as shown in Figure 5) is the key part of lubricating oil pump in certain vehicle, is all for many years to rely on import,
The manufacturing process country is not yet broken through, and existing processing method needs dedicated copying lathe (not can guarantee the notch and end face wave at step
Shape has relative positional relationship) or five kinematic axis machining center.Existing turbine (gear) processing technology, to the step of end face and
Taper WEDM is relatively easy to, and the wave mode end face main critical technological point of part is that its part end face is three-dimensional waveform curvature portion
Processing technology, the present invention can be not only made to meet the emphasis technique that the production domesticization of key components and parts needs and carries out and break through
China gets rid of the technology dependence to developed country, and to domestic equipment manufacturing technical level is promoted, to turning-milling complex processing
Center has certain facilitation using horizontal raising.
For at present, when being normally applied complex milling machine tool based on milling radial shape, when milling axial shape
Seldom.Processing difficulties have been captured under the continuous tackling key problem of technical staff, using turning-milling complex processing, have passed through test of many times, success
The part (waveform turbine) for the imported product that is enough to match in excellence or beauty is processed.
Summary of the invention
It is an object of the present invention to provide a kind of processing methods for being directed to parts peculiar waveform turbine (gear), are processed by this
Technique (model XKC-S16B) can realize the processing of end face waveform three-dimensional structure on CNC sliding headstock auto-lathe, while can control it
Angle position of the remaining processing department split-phase for waveform.
The present invention is achieved by the following technical scheme:
A kind of waveform turbine (gear) processing method, includes the following steps:
(1), round bar pin type tooling is prepared
Round bar pin type tooling includes the oval body of rod, and step inner hole, the oval body of rod one are equipped in described oval body of rod one end
End side surface is provided with dowel hole.
(2), it blanking and is heat-treated.
(3), part mid-module, numerical control turning machine model: XKC-30F vehicle: are processed by part process schematic diagram；
The part mid-module completed the process includes turbine body, and the turbine body side is integrally extended with technique collet round bar, institute
Stating technique collet round bar end face has the step matched with the step inner hole in oval body of rod one end convex, and the turbine body is another
One side is reserved with the boss for machine-shaping part side step, and part axial hole is machined at the boss.
(4) it beats location hole: opening up dowel hole on the technique collet round bar of part mid-module.
(5) turnning and milling is compound: numerical control lathe, lathe model: XKC-S16B complex milling machine tool, processes end face waveform；
According to the shape of forming part, middle part is hole axle, then front end face is specially that 8 type faces are distributed with centered on hole axle,
Respectively type face 1, type face 2, type face 3, type face 4, type face 5, type face 6, type face 7, type face 8, medium-sized face 2 and type face 6 are symmetrical simultaneously
As concave plane, type face 4 and type face 8 are symmetrically and as convex flat face, inclined-plane of the type face 1 as connecting-type face 2 and type face 8, type face 3
As the inclined-plane in connecting-type face 2 and type face 4, inclined-plane of the type face 5 as connecting-type face 4 and type face 6, type face 7 is used as connecting-type face 6
With the inclined-plane in type face 8, hole axle has part side step between type face 1 and type face 3.Similarly, part rear end face is specially
8 type faces, respectively type face 9, type face 10, type face 11, type face 12, type face 13, type face 14, type face are distributed with centered on hole axle
15, type face 16, medium-sized face 9 is corresponding with type face 7, and type face 10 is corresponding with type face 8, and type face 11 is corresponding with type face 1, type face 12 and type
Face 2 is corresponding, and type face 13 is corresponding with type face 3, and type face 14 is corresponding with type face 4, and type face 15 is corresponding with type face 5, and type face 16 and type face 6 are right
It answers.
Process is as follows:
Firstly, part mid-module to be inserted into the step inner hole of round bar pin type tooling one end by its technique collet round bar, so
Afterwards by pin shaft insertion process collet round bar and the corresponding dowel hole of the oval body of rod, part mid-module and round bar pin type are completed
The assembly of tooling；Round bar pin type tooling is finally installed on machine tool chief axis；
Start lathe, milling cutter is made to start to rotate into milling preparation state；At this point, milling cutter is located at part front end face；Use lathe
X, Z, C three-shaft linkage functional localization milling cutter to type face 8 and 1 transition arc of type face starting point；With the function of Z, C two-axle interlocking
According to the requirement of part front shape, point-by-point fitting processes the transition arc between type face 8 and type face 1, then finishing type face 1
Processing；Type face 1 is after processing is completed with the transition arc between point-by-point fit approach processing type face 1 and type face 2；Transition arc processing
After the completion, forming surface 2 is processed with C s function；Be fitted point by point with Z, C two-axle interlocking function again process type face 2 and type face 3 it
Between transition arc, the then processing in finishing type face 3；After the completion of type face 3, processed between type face 3 and type face 4 with point-by-point fitting
Transition arc；Forming surface 4 is processed with C s function again；To first circulation that end face waveform is completed herein；With such
It pushes away, completes the processing of the part front totally 2 waveform cycles；
The rear end face that milling cutter is moved to part, using X, Z, C three-shaft linkage functional localization milling cutter of lathe to type face 16 and type face 9
Between transition arc starting point；Point-by-point fitting is required to process according to part front shape with the function of Z, C two-axle interlocking
Transition arc between type face 16 and type face 9, the then processing in finishing type face 9；Then with point-by-point fit approach processing type face 9 with
