Embodiment
The technical scheme in the utility model embodiment will be clearly and completely described below, it is clear that described
Embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.Based on the implementation in the utility model
Example, all other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to
The scope of the utility model protection.
Referring to Fig. 1, the utility model embodiment includes：
A kind of device for processing approximate log shape roller, including：
Emery wheel 1, the emery wheel with depression arc, is ground to roller 9.
Guide wheel 2, the guide wheel with convex bulging arc drives the rotation of roller 9 to promote.
It is grinding area between emery wheel 1 and guide wheel 2, grinding zone position is controlled by adjusting means 3.
Emery wheel 1 and the side of guide wheel 2 are equipped with corrector 4 and gauge finder 5.
The corrector 4 is driven by oil cylinder 6, and contacts profiling with gauge finder 5 by the V-shaped part on corrector 4.
Gauge finder 5 carries interior radian or outer radian, is that amendment emery wheel 1 or guide wheel 2 provide arc benchmark.
Support plate 7 is provided between emery wheel 1 and guide wheel 2, support plate 7 plays a part of supporting roller 9, and with approximate guide wheel
The outer radian of 2 gauge finders.
The import of grinding area is all provided with restricted roller 9 with outlet and is oriented to feeding or the guide plate 8 sent out.
The utility model has carried out the improvement to gauge finder 5, support plate 7, makes its motion under the lifting of support plate of roller 9
Track is moved along the convex bulging arc track of guide wheel 2, and the radian of roller bus is realized by the emery wheel with depression arc.
The utility model further relates to a kind of processing technology for processing approximate log shape roller, comprises the following steps：
1）Roller bus is processed as one section of amendment by pre-grinding arc slope, the arc action of pre-grinding 70%-80% × Lw sections of roller length
Linear curve, the pre-grinding radius for defining emery wheel is R sand, and the pre-grinding radius of guide wheel is led for R, and R leads ≈ R sand × K in advance, and COEFFICIENT K is pre-
=0.75~0.88.
To realize that approximate log is laid a good foundation, the complicated design of approximate log superfinishing deflector roll is avoided and approximate right
The accurate processing of number deflector roll.
2）Approximate log curve is refined, on the curve of modified line shape, is processed using superfinishing deflector roll, you can obtains near
Like logarithmic curve, wherein, the super ≈ R sand × K of fine grinding radius R of superfinishing deflector roll surpass, COEFFICIENT K super=0.6~0.65.
The processing method is conducive to bus to intersect with radian, radian and chamfering intersection rounding off, while ensure that near
Specifically required like logarithmic curve change.
Embodiment 1：By taking φ 9xl4 rollers as an example.
1）Pre-grinding arc slope, the arc action of 75% × Lw sections of completion, is commonly called as convexity.Emery wheel gauge finder R is set as 2500mm, and
Guide wheel gauge finder R is 2000mm, the R of emery wheel, guide wheel can be avoided because of the interference produced by decentraction, adjustment adjusting means can improve
The diameter difference of roller two ends diameter.
The roller of table one can obtain following technological parameter after being processed through pre-grinding arc slope：
Now, roller bus actual curve is the linear curve of one section of amendment, as shown in table one, in order to reach theoretical ginseng
Number, pre-grinding R is using R sand 2500mm, and R leads 2000mm, and R leads ≈ R sand × K in advance, and COEFFICIENT K is in advance=0.75~0.88；It can avoid preventing
Process caused by R sand and R lead decentraction is interfered.In camber line and straight edge line in the curve theory of roller bus now
At friendship, also there is wedge angle in camber line, with chamfering intersection so stress concentration is still present.
2）Approximate log curve is refined,
On the curve of modified line shape, it is processed using superfinishing deflector roll, R surpasses for 1500, can be obtained after convexity ultra-precision grinding
To the approximate log curve that it is as shown in the table, each precision parameter is as shown in Table 2：
The key point of approximate log is realized, superfinishing deflector roll selects the R2500 than pre-grinding to reduce, and K supersystems number is 0.6, i.e. K
≈ 1500 of super super ≈ R2500 of=0.6, R × O.6, it is ensured that infinite when approximate log curve tends to straight line in 50%th area is approached
With it is outer and chamfering intersection tends to rounding off formed by infinite approach 83%.
The actual curve of table two is to meet the whole precision indexs of theoretical curve.
The utility model simplifies approximate log processing method, and realizing medium-sized and small enterprises also can conveniently process approximate log song
Line roller, and due to the method using pre-grinding convexity, the roller proximal end diameter difference after superfinishing（Asymmetry）Also it is effectively improved.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure or equivalent flow conversion made using the utility model description, or directly or indirectly it is used in other phases
The technical field of pass, is similarly included in scope of patent protection of the present utility model.
