Specific embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common
All other embodiment that technical staff is obtained under the premise of creative work is not made, belongs to the model of present invention protection
Enclose.
Fig. 1 is referred to, the embodiment of the present invention 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 propulsion of roller 9.
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 and is oriented to feeding or the guide plate 8 sent out with outlet.
The present invention has carried out the improvement to gauge finder 5, support plate 7, makes its movement locus under the lifting of support plate of roller 9
Moved along the convex bulging arc track of guide wheel 2, the radian of roller bus is realized by the emery wheel of band depression arc.
The invention further relates to a kind of processing technology for processing approximate log shape roller, comprise the following steps：
1）Pre-grinding arc slope, the arc action of pre-grinding 70%-80% × roller length Lw sections, is processed as one section of amendment linear by roller bus
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 it is pre- that R leads ≈ R sand × K, 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 right with approximate
The accurate processing of number deflector roll.
2）Fine grinding approximate log curve, on the curve of modified line shape, is processed using superfinishing deflector roll, you can obtain 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, completes 75% × Lw sections of arc action, is commonly called as convexity.It is 2500mm to set emery wheel gauge finder R, and
Guide wheel gauge finder R is 2000mm, and the R of emery wheel, guide wheel can be avoided because of the interference produced by decentraction, and 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 parameter, in advance
Using R sand 2500mm, R leads 2000mm to mill R, and R leads ≈ R sand × K in advance, and COEFFICIENT K is in advance=0.75~0.88；Can avoid preventing because of R sand
The process caused by decentraction is led with R to interfere.In the curve theory of roller bus now at camber line and straight edge line friendship,
Also there is wedge angle in camber line, with chamfering intersection so stress concentration is still present.
2）Fine grinding approximate log curve,
On the curve of modified line shape, it is processed using superfinishing deflector roll, it is 1500 that R surpasses, is can obtain such as after convexity ultra-precision grinding
Approximate log curve shown in table, each precision parameter is as shown in Table 2：
Realize the key point of approximate log, superfinishing deflector roll from being reduced than the R2500 of pre-grinding, K supersystems number be 0.6, i.e. K it is super=
≈ 1500 of 0.6, R super ≈ R2500 × O.6, it is ensured that infinite when approximate log curve tends to straight line in 50%th area approach and
The rounding off that outside 83% and chamfering intersection tends to infinite approaching and formed.
The actual curve of table two is to meet theoretical curve whole precision index.
This invention simplifies approximate log processing method, realizing medium-sized and small enterprises also can conveniently processing approximate log curve rolling
Son, and due to the method using pre-grinding convexity, the roller proximal end diameter difference after superfinishing（Asymmetry）Also it is effectively improved.
