Description
Technical field
The present invention relates to a kind of gear machining technology, relate to specifically a kind of grinding die of duplicate gear pinion.
Background technology
During current conventional gear grinding, mainly adopt the operating process of corase grind, half fine grinding and fine grinding, the major parameter of gear grinding Performance Detection is gear circular runout and tooth pitch deviation, the every stroke amount of feeding of corase grind grinding is slightly large is 0.03mm substantially, partly refine every stroke amount of feeding at 0.02mm, refine every stroke amount of feeding at 0.01mm.The grinding wheel speed of corase grind is also distinguished to some extent with the rotating speed of fine grinding.Such method for grinding can also reach at 6 class precisions that guarantee the form of gear tooth, teeth directional, but often occurs surpassing the phenomenon of 6 grades of tolerances during the numerical value of keeping under strict supervision close inspection tooth pitch deviation and circular runout.Some gear circular runouts reach 9 grades unexpectedly, and this jitter values judges the underproof principal element of the accuracy of gear when overproof.
Although the teeth grinding method of existing routine is divided into slightly, half smart and fine grinding three circle realizations, the teeth grinding method of this routine causes the gear of producing obviously to be beated with regard to occurring every several teeth.This generation of beating is with the Buddha's warrior attendant running roller abrasive grinding wheel in gear grinding machines, to become the shape of teeth groove just because of the principle of form grinding, and carry out the part that leaves tooth after grinding teeth groove with this emery wheel, is exactly the parameter value that profile of tooth requires.So the parameters precision of each tooth depends on parameter and the shape of roll flute emery wheel completely.Yet the several teeth of the every grinding of emery wheel are because sand grains and gear teeth face contacts passivation and come off, surface changes, and causes tooth parameter that grinding goes out to have nuance between each.For guaranteeing the machining accuracy of postorder teeth groove, just need according to grinding and feeding amount at every turn number carry out again the grinding action of all the other teeth after grinder buffing is sharp with Buddha's warrior attendant running roller in time.But the impact just because of this regular grinding wheel, while causing first tooth of the wheel grinding of just having polished and emery wheel to be about to polish after being worn out, the profile of tooth of last tooth of grinding just obviously shows difference in tooth pitch deviation, and such roll flute operates in half fine grinding and fine grinding repeats time, gradually the accumulation of error, has also just formed obviously beating with regard to occurring every several teeth of the whole left flank of tooth of gear or the right flank of tooth.
As shown in Figure 1 and Figure 2, duplicate gear comprises pinion A, gear wheel B, and pinion A gear wheel B one connects, and between described pinion A and gear wheel B, is provided with push broach groove; Add man-hour, it is that 1.6 μ m can not reach instructions for use that pinion A completes rear surface fineness at gear shaping, between each tooth at gear after adopting above-mentioned grinding method grinding, there will be significantly and beats.
Summary of the invention
The problem to be solved in the present invention is for overcoming above-mentioned technological deficiency, and a kind of grinding die that also can guarantee the duplicate gear pinion of grinding accuracy when can effectively avoid circular runout is provided.
In order to address the above problem, the present invention by the following technical solutions:
The grinding die of duplicate gear pinion, comprise die shoe, upper bolster, described die shoe and upper bolster are slidably connected by guide pillar, described die shoe top is provided with for the fixing counterdie of duplicate gear, the corresponding position of mould, described upper bolster up and down is in transmission connection and is useful on the flute profile grinding attachment of grinding duplicate gear pinion, and described flute profile grinding attachment relatively counterdie moves up and down.
Below further improvement of the present invention:
Flute profile grinding attachment comprises the grinding cutter of several circular array, and the grinding cutter of several circular array and tooth on duplicate gear pinion are corresponding and match with the profile of tooth on duplicate gear pinion one by one.
Further improve:
Described flute profile grinding attachment can be done intermittent rotation relative to counterdie, and its rotation angle is once identical with the space width between adjacent teeth on duplicate gear pinion.
Further improve:
The Power Drive Unit that drives flute profile grinding attachment to rotate is installed on described upper bolster.
Further improve:
Power Drive Unit comprises the motor fixing seat being fixed on upper bolster, in described motor fixing seat, be fixedly connected with RV reductor, the power intake of described RV reductor is connected with servomotor, and the clutch end of RV reductor is fixedly connected with flute profile grinding attachment.
Further improve:
In described counterdie, be provided with for by the alignment pin of duplicate gear and counterdie location.
Further improve:
The quantity of described alignment pin is at least two.
Further improve:
The lower end of described flute profile grinding attachment is provided with electronic stopper, and electronic stopper, for limiting the stroke of flute profile grinding attachment, prevents flute profile grinding attachment excess of stroke destruction workpiece when descending.
The present invention adopts such scheme, each tooth to pinion in duplicate gear carries out while grinding, patrix completes grinding process one time, in backhaul process, rotate to an angle and guarantee in process for the second time different position on grinding worm, so repeatedly can guarantee that on pinion, each tooth grinding is even, guarantee grinding accuracy, reduced Grinding Error; The circular runout of simultaneously having avoided single gear grinding to bring, has guaranteed the uniformity of gear wheel and pinion position; Improve production efficiency, reduced production cost, can be used for batch production; The precision of RV reductor swing offset is high, can guarantee the degree of accuracy of grinding cutter and gear location, improves machining accuracy.
Below in conjunction with drawings and Examples, the invention will be further described.
