Abstract
The invention discloses and a kind of ensure the processing method of external splines axiality in hollow shaft, it completes the processing of external splines in hollow shaft according to following steps: step one, rough turn hollow shaft left end end face, cylindrical, hole and hollow shaft right-hand member end face, cylindrical, hole；Step 2, hollow shaft two ends are joined stifled, centering；Step 3, with two ends centre bore location finish turning hollow shaft left end cylindrical and hollow shaft right-hand member cylindrical；Step 4, grinds hollow shaft left end cylindrical, by face grinding A；Step 5, grinds hollow shaft right-hand member cylindrical, by face grinding B, C；Step 6, goes to block up；Step 7, with hollow shaft left end cylindrical and end face A for centering benchmark, grinds hollow shaft left end endoporus, by face grinding E；Step 8, on gear shapping machine, plug hole mandrel left end internal spline；Step 9, is placed directly in workpiece on gear shaper workbench and positions with end face E face, and plug hole mandrel right-hand member external splines can complete the processing of workpiece.Ensure that the unification of hollow shaft inside and outside spline locating and machining benchmark and centering benchmark, improve machining accuracy.
Description
Technical field
The present invention relates to machine industry processing hollow shaft type workpiece inside and outside spline processing technique field, tool
Say it is a kind of to ensure the processing method of external splines axiality in hollow shaft body.
Background technology
At present, in the prior art, it is ensured that the processing of hollow shaft inside and outside spline axiality, annoying always
Each processing technique field, when processing inside and outside spline, positioning datum and centering benchmark are not unified all the time, tradition
Processing technology be: rough turn-mill stifled-centering-fine turning outer circle-cylindrical grinding of splined hole-join-go blocks up-inserts interior
Spline-insert external splines.Now rear institute's processing excircles center is blocked up not at a center line with joining in internal splined hole center
On.Reason is exactly that the center after grinding out is not with joining center stifled, centering, turning, cylindrical grinding
One benchmark, so causing inside and outside spline ensuring coaxiality not.That is technological datum is not one
Benchmark, affects product assembly quality, main shortens product service life.This processing method is the fullest
The high quality of products design requirement that foot is not the most present.
Summary of the invention
It is an object of the invention to, overcome the defect of existing technique, it is provided that external splines in a kind of guarantee hollow shaft
The processing method of axiality, redesigns new technological method for processing, it is ensured that the inside and outside spline of hollow shaft
Axiality.
The technical solution adopted for the present invention to solve the technical problems is, completes in hollow shaft according to following steps
The processing of external splines: step one, rough turn hollow shaft left end end face, cylindrical, hole and hollow shaft right-hand member end face,
Cylindrical, hole；Step 2, hollow shaft two ends are joined stifled, centering；Step 3, positions with two ends centre bore
Finish turning hollow shaft left end cylindrical and hollow shaft right-hand member cylindrical；Step 4, grinds hollow shaft left end cylindrical, by mill end
Face A；Step 5, grinds hollow shaft right-hand member cylindrical, by face grinding B, C；Step 6, goes to block up；Step 7,
With hollow shaft left end cylindrical and end face A for centering benchmark, with right-hand member cylindrical as positioning datum, grind hollow shaft left end
Endoporus, by face grinding E；Step 8, on gear shapping machine, plug hole mandrel left end internal spline, look for when inserting internal spline
Positive hollow shaft left end cylindrical and end face E face, with end face B face or C face as positioning datum；Step 9, plug hole
Mandrel right-hand member external splines, centering hollow shaft right-hand member cylindrical and end face C when inserting external splines, with E face as positioning datum.
The invention has the beneficial effects as follows, owing to having unified positioning datum and the centering benchmark of splined hole and cylindrical,
Ensure that the splined hole positioning datum with cylindrical is same benchmark with centering benchmark, thus improve internal spline with outer
The axiality requirement of spline.Thoroughly solve the inside and outside overproof problem of spline axiality, improve adding of workpiece
Work precision, and simple to operate, easy to use.
Accompanying drawing explanation
Fig. 1 is the manuscript of finish turning of the present invention, cylindrical grinding；
Manuscript when Fig. 2 is gear shaping of the present invention.
In figure: A, B, C, E are hollow shaft end face.
Detailed description of the invention:
From Fig. 1～2, mill splined hole operation is changed to cylindrical grinding aft-loaded airfoil, and necessary during cylindrical grinding
Mill associated end face to be leaned on, so just can be with centering cylindrical grinding and leaned on face grinding during mill splined hole, it is ensured that flower
Keyhole and the same center of cylindrical.In guarantee hollow shaft, the procedure of processing of external splines axiality is as follows:
The processing of external splines in hollow shaft is completed according to following steps:
Step one, rough turn hollow shaft left end end face, cylindrical, hole and hollow shaft right-hand member end face, cylindrical, hole；
Step 2, hollow shaft two ends are joined stifled, centering；
Step 3, with two ends centre bore location finish turning hollow shaft left end cylindrical and hollow shaft right-hand member cylindrical；
Step 4, grinds hollow shaft left end cylindrical, by face grinding A；
Step 5, grinds hollow shaft right-hand member cylindrical, by face grinding B, C；
Step 6, goes to block up；
Step 7, with hollow shaft left end cylindrical and end face A for centering benchmark, with right-hand member cylindrical as positioning datum,
Mill hollow shaft left end endoporus, by face grinding E；
Step 8, on gear shapping machine, plug hole mandrel left end internal spline.Centering hollow shaft left end when inserting internal spline
Cylindrical and end face E face, with end face B face or C face as positioning datum；
Step 9, plug hole mandrel right-hand member external splines, centering hollow shaft right-hand member cylindrical and end face when inserting external splines
C, with E face as positioning datum.
Should be appreciated that above is to show by preferred embodiment to the detailed description that technical scheme is carried out
Meaning property and nonrestrictive.Those of ordinary skill in the art can on the basis of reading description of the invention
So that the technical scheme described in embodiment is modified, or wherein portion of techniques feature is carried out equivalent replace
Change；And these amendments or replacement, do not make the essence of appropriate technical solution depart from embodiment of the present invention technology
The spirit and scope of scheme.
