Technical field
The utility model is related to the processing tools of the automotive transmission conjunction gear fine forge piece of automobile, especially automobile variable speed
The device conjunction gear thin-walled gear ring endoporus Vehicle Processing core that rises.
Background technology
Automotive transmission combination gear is one of vital part of automobile gearbox, the gear parameter and performance indicator compared with
Height, the performance indicators such as machining accuracy directly determine automotive transmission total quality, and then determine vehicle motor overall performance.
In the prior art, it is thin-wall workpiece because this combines toothed ring gear, is easily deformed using common self-centering three-jaw when processing, gear ring endoporus
Size requires tolerance within 0.016, and circularity causes after lathe process between 0.008-0.015 without change after actual processing
Dynamic tolerance range, it is difficult to reach higher performance indicator, it is difficult to meet the needs of actual production.Moreover, the performances such as its machining accuracy
Index directly determines that automotive transmission total quality is not high, reduces vehicle motor overall performance.In addition, what machining generated
Waste product is higher, reduces production efficiency, and the cost of workpiece is higher.
Invention content
The utility model is difficult to reach higher performance indicator, is difficult to meet reality for the machining of existing speed changer conjunction gear
The deficiencies of needs of border production, manufactures and designs a kind of automotive transmission conjunction gear thin-walled gear ring endoporus Vehicle Processing core that rises, machine adds
Gear blank is sleeved on this and risen on core positioning surface by working hour, and strength is cut in receiving portion cutting, obtains higher circularity etc..
The technical solution of the utility model：The automotive transmission conjunction gear thin-walled gear ring endoporus Vehicle Processing core that rises,
Including ontology, it is characterised in that：The ontology is revolving body, has centre bore, is arranged on the boss of ontology lower end
There are stepped hole and threaded hole；Ontology upper end is the cylinder of thin slice, and the lateral surface of cylinder is machining positioning surface, the medial surface of cylinder
It is inclined-plane.
Further feature is：In the lower end of cylinder, it is disposed radially several cross-drilled holes.
The cross-drilled hole is threaded hole.
The center line of each cross-drilled hole is generally aligned in the same plane, and cross-drilled hole is evenly distributed in the circumferential direction.
The utility model automobile automotive transmission conjunction gear thin-walled gear ring endoporus Vehicle Processing core that rises, relative to existing skill
Art has following feature：
1, gear ring circularity increases substantially：Circularity≤0.007mm, lathe ensure that dimensional tolerance can expire within 0.007
Foot production.
2, production rejection rate is improved by early period 30% to 3%, reduces the machining cost of workpiece.
3, the machining production efficiency for improving workpiece, also reduces processing cost.
Description of the drawings
Fig. 1 is that the utility model rises the sectional structure chart of core；
Fig. 2 is the left view of Fig. 1；
Fig. 3 is the right view of Fig. 1；
Fig. 4 be the utility model rise core processing use state diagram.
Specific implementation mode
As shown in Figure 1,2,3, 4, the automotive transmission conjunction gear thin-walled gear ring endoporus Vehicle Processing core that rises of the utility model,
Including ontology 1, the ontology 1 is revolving body, has centre bore 2, stepped hole 3 and screw thread are provided on the boss of 1 lower end of ontology
Match with other component respectively by penetrating the bolt of adapted in stepped hole 3, penetrating the screw etc. of adapted in threaded hole 4 in hole 4
Close connection；1 upper end of ontology is the cylinder 5 of thin slice, and the lateral surface of cylinder 5 is machining positioning surface 6, and the medial surface of cylinder 5 is oblique
Face 7.When processing, machining positioning surface 6 and semi-finished product gear workpieces interior side contacts to be processed, the matched pull rod of processing
It penetrates and rises in core centre bore 2, coordinate with inclined-plane 7, radially outer active force, tensioner semi-finished product to be processed are generated to inclined-plane 7
Gear workpieces prevent gear workpieces when machining from deforming, ensure gear ring circularity.
In the lower end of cylinder 5, several cross-drilled holes 8 are disposed radially, cross-drilled hole 8 is evenly distributed in the circumferential direction, each horizontal
The height of the center line in hole 8 is equal, or is generally aligned in the same plane；The cross-drilled hole 8 can be processed as threaded hole according to processing needs.
The effect of cross-drilled hole 8 is to eliminate stress in tensioner, because laminar cylinder 5 easily fractures, 5 folding of cylinder when preventing tensioner from acting on
It is disconnected.
In use, by the automotive transmission conjunction gear thin-walled gear ring endoporus Vehicle Processing core that rises of the utility model, first with
Ring flange is connected and is fixed, and flange terminal pad is connected on lathe spindle；Then by semi-finished product gear workpieces set to be processed
On machining positioning surface 6, and the positioning disk shared in 5 outer sheath establishing of cylinder, positioning disk are located at gear blank to be processed
Between the outside of cylinder 5, then the centre bore that the matched pull rod of processing is penetrated to semi-finished product gear workpieces to be processed,
Rise in core centre bore 2, pull pull rod, pull rod that the cylinder 5 of thin slice is then pushed to generate outward force, act on to be processed half at
On the inside of product gear workpieces, positioning and the active force for offsetting machining generation；After installation connects, starts numerically controlled lathe and add by technique
Work obtains qualified part.Specifically：Preparatory technology requires cutter, editor's nc program to carry out examination processing, processing blades
TNMG160408-TS T9125,1200 revs/min of rotating speed, feed 0.12mm/ turn, and confirm and carry out batch after part processing is qualified
Processing.
Finally, it should be noted that above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application technology
Scheme, although applicant is described in detail the utility model with reference to preferred embodiment, those skilled in the art
It should be appreciated that those are modified or replaced equivalently the technical solution of the utility model, without departing from the technical program
Objective and range should all cover in the right of the utility model.
