It is scheduled on left end cap；The right mandrel is fixed on the left tailstock spindle of gear shaving machine, and the right end cap is fixed on right mandrel, described
Right gland is fixed on right end cap.
The limit sleeve is fixed on spline ringfeder.
The left mandrel is provided with the male cone (strobilus masculinus) to match with spline ringfeder, and spline ringfeder and limit sleeve are fixed on one
It rises and then fills in workpiece to be processed hole.When in the first extreme position, spline ringfeder inner hole and left mandrel male cone (strobilus masculinus) match grinding.
It is preferred: to have aperture in the middle part of the spline ringfeder, slot on the side wall of through-hole, the inner hole of spline ringfeder is processed into
Inner conical surface, there are four threaded holes for the osculum end face of spline ringfeder, for fixing limit sleeve.
Preferred: left mandrel and spline ringfeder faying face have a male cone (strobilus masculinus) with spline ringfeder equal angular, in spline ringfeder
Match grinding at hole and left mandrel taper.
It is preferred: spline ringfeder and involute inner spline tooth parameter having the same.
Preferred: the limit sleeve is split type limit sleeve.
The utility model compared with prior art, has the advantages that
The utility model not only greatly facilitates artificial loading and unloading, shortens processing beat, and is later automation
Processing provides possibility, it is most important that improves production efficiency.
Detailed description of the invention
Fig. 1: fixture schematic cross-sectional view
In figure: the right gland 6- right end cap 7- limit sleeve of the left gland 4- spline ringfeder 5- of the left mandrel 2- left end cap 3- of 1-
The right mandrel of 8- tight sleeve 9-.
Specific embodiment
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate, it should be understood that these examples are only used for
Bright the utility model rather than limitation the scope of the utility model, after having read the utility model, those skilled in the art
Member falls within the application range as defined in the appended claims to the modification of the various equivalent forms of the utility model.
A kind of automatic Fixture for Gear-shaving of expansion sleeve type, as shown in Figure 1, including left mandrel 1, left end cap 2, left gland 3, spline ringfeder
4, right gland 5, right end cap 6, limit sleeve 7, tight sleeve 8, right mandrel, the left mandrel 1 and right mandrel are fixed on gear shaving machine or so
On tailstock spindle, left end cap 2 is fixed on left mandrel 1, and the left gland 3 is fixed on left end cap 2, and the right end cap 6 is fixed
On right mandrel, the right gland 5 is fixed on right end cap 6, and the left mandrel 1 is provided with to match with spline ringfeder 4
Spline ringfeder 4 and limit sleeve 7 are fixed together and then are filled in workpiece to be processed hole by male cone (strobilus masculinus).In the first extreme position
When, 4 inner hole of spline ringfeder and left 1 male cone (strobilus masculinus) match grinding of mandrel.
Aperture is had in the middle part of the spline ringfeder 4, is slotted on the side wall of through-hole, the inner hole of spline ringfeder 4 is processed into inner cone
Face, there are four threaded holes for the osculum end face of spline ringfeder 4, for fixing limit sleeve 7.
Left mandrel 1 and 4 faying face of spline ringfeder have a male cone (strobilus masculinus) with 4 equal angular of spline ringfeder, 4 inner hole of spline ringfeder with
Match grinding at left 1 taper of mandrel.
Spline ringfeder 4 and involute inner spline tooth parameter having the same.
There is the interface being connected with tailstock spindle in right mandrels tail portion.
The limit sleeve 7 is split type limit sleeve, is fixed on spline ringfeder in this way, will not influence the spreading of spline ringfeder
And contraction, while major function is after the completion of work pieces process, for left mandrel toward when retraction, spline ringfeder will not be with left mandrel
It returns, is still retained in workpiece hole together.
Right mandrels are all made of 40Cr material, and spline ringfeder material is 65Mn material.
The processing technology of the utility model is as follows: before processing, workpiece is not integrated with fixture, but is separated
, when only workpiece is in Working position, clamp workpiece, workpiece rotates together with fixture, relative velocity 0, completes to add
Work process.Left mandrel 1 and right mandrel 9 are fixed on gear shaving machine or so tailstock spindle, and left end cap 2 and right end cap 5 are separately fixed at
On left mandrel 1 and right mandrel 9.Spline ringfeder 4 and limit sleeve 7 are fixed together and then are filled in workpiece hole before undressed
In.Place into automatic loading and unloading device, then workpiece is sent to machining position, right mandrel 9 be fixed on right tailstock spindle first with
Fixed journey system push, since right gland 5 and right end cap 6 are fixed on right mandrel 9, so right gland 5 first touches workpiece right end
Face.Then left mandrel 1 is released to the right again, while release, 4 spreading of spline ringfeder, until left 3 workpiece pressing left side of gland is
Only, terminate the clamping process of entire fixture.
The above is only the preferred embodiment of the utility model, it should be pointed out that: for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
