To operator without technical requirements.
Embodiment
Below in conjunction with example, the present invention is further described.
A kind of generating method gear grinding machines digital control system, comprise PLC programmable logic controller, touch-screen, servomotor and worktable, described touch-screen connects PLC programmable logic controller, described PLC programmable logic controller (PLC) controls servomotor moves, described servomotor drives worktable to become relative movement with the exhibition of workpiece, it is achieved to the grinding of involute gear.
A control method for generating method gear grinding machines digital control system, comprises the following steps:
To process ZL50 type shovel loader oil pump gear, tooth number Z=12, modulus M=5 with y7132 gear grinding machines;
1, inputting tooth number Z, modulus M by touch-screen, PLC programmable logic controller carries out float-point arithmetic, draws following numerical value successively:
(1) the round as a ball girth C of workpiece is calculated, C=Z*M*3.1416=12*5*3.1416=188.496 millimeter=188496 micron (if helical teeth, C=(Z*M*3.1416)/cos ��, �� is pitch angle), wherein Z is the number of teeth, M is modulus, and namely adjacent two teeth are with the ratio of the tooth pitch p between the flank profil of side and pi;
(2) calculate workpiece rotate a circle umber of pulse N, N=servomotor run one week umber of pulse * step-down gear reduction ratio; (Y7132 gear grinding machines workpiece rotary worm head number is: 1; The worm gear number of teeth is: 120, and therefore reduction ratio is: 120), therefore, and 10000*120=1200000 pulse/week.
(3) point dentition number FX, a FX=N/C=1200000/188496=6.36618 is calculated;
(4) calculating workpiece and rotate interpolation value, length opened up into by worktable is 60000, and workpiece rotates interpolation value=worktable and opens up into length * FX=60000*6.36618=381970.8; Get 381971, less than 1 pulse, do not affect precision; The track gone out by this numerical value interpolation and standard involute path.
2, adjust worktable servo-driver electronic gear proportion so that it is corresponding one 0.001 millimeter of pulse, then worktable opens up into length and servomotor runs umber of pulse;
Believing EP-100 driving mechanism for wheat, PA12/PA13=5/3, then driving mechanism often receives a pulse, movable workbench one 0.001 millimeter.
The electronic gear proportion of servo illustrates: is point frequency multiplication by changing electronic gear proportion, realizes different pulse equivalents. The line number that the precision of servosystem is encoder determines, but this is only the precision of servomotor. Connecting different physical construction in practice, such as ball-screw, worm gear worm gear pair, the parameter such as pitch, the number of teeth is different, and mobile amount of motor rotation needed for least unit amount is different. Electronic gear proportion is the minimum mobile amount of coupling motor pulses number and machinery. The electronic gear proportion arranging servo needs to know, mechanical drive department assigns to the transmitting ratio between motor, is exactly that motor revolves and turns around, and mechanical part rotates how many.
Such as, servomotor code-disc 2500 line, system 4 frequency multiplication, leading screw pitch L=6mm, direct-connected, then: PA12/PA13=4x2500/6x1000=10000/6000=10/6=5/3.
3, when worktable operates, workpiece synchronous rotary, the involute urve that its workpiece rotates the track shown in interpolation value and gear launches track.
In addition, it is possible to adjusted the deviation of profile of tooth generation by amendment point dentition number.
The present invention is not limited to above-mentioned enforcement mode, and anyone should learn the change made under the enlightenment of the present invention, and every have identical or close technical scheme with the present invention, all falls within protection scope of the present invention.
Technology that the present invention does not describe in detail, shape, structure part are known technology.
