Description
Technical field
The utility model relates to gear machining technology, relates to specifically a kind of grinding die of duplicate gear pinion.
Background technology
Mainly adopt corase grind, half operating process of finish grinding and finish grinding during present gear grinding commonly used, 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 to be 0.03mm substantially, partly finish grind every stroke amount of feeding at 0.02mm, finish grind every stroke amount of feeding at 0.01mm.The corase grind grinding wheel speed with also with the correct grinding rotating speed distinguish to some extent.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, judge the underproof principal element of the accuracy of gear when this jitter values is overproof.
Although existing conventional teeth grinding method is divided into slightly, half essence and finish grind three circles and realize, the teeth grinding method of this routine cause the gear produced every several teeth just appearance obviously beat.This generation of beating is the shape that becomes teeth groove with the Buddha's warrior attendant running roller abrasive grinding wheel in the gear grinding machines just because of the principle of form grinding, is exactly the parameter value that profile of tooth requires and come the part that stays tooth behind the grinding teeth groove with this emery wheel.So the parameters precision of each tooth depends on parameter and the shape of roll flute emery wheel fully.Yet the several teeth of the every grinding of emery wheel are because the contacting passivation and come off of sand grains and gear teeth face, and the surface changes, and cause tooth parameter that grinding goes out to have nuance between each.Be to guarantee the machining accuracy of postorder teeth groove, just need according to the timely grinding action of carrying out again all the other teeth after with the Buddha's warrior attendant running roller that grinder buffing is sharp of what of each grinding and feeding amount.But the impact just because of this regular grinding wheel, the profile of tooth of last tooth of grinding just obviously shows difference when causing first tooth of the wheel grinding of just having polished and emery wheel to be about to polish after being worn out on the tooth pitch deviation, and such roll flute operates in half correct grinding and correct grinding repeats the 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 is provided with the push broach groove between described pinion A and the gear wheel B; Add man-hour, it is that 1.6 μ m can not reach instructions for use that pinion A finishes rear surface fineness at gear shaping, can occur between each tooth at gear after adopting above-mentioned grinding method grinding significantly beating.
Summary of the invention
Problem to be solved in the utility model 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 utility model by the following technical solutions:
A kind of grinding die of duplicate gear pinion, comprise die shoe, upper bolster, described die shoe and upper bolster are slidingly 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 be further improvement of the utility model:
The flute profile grinding attachment comprises the grinding cutter of several circular array, and the tooth on the grinding cutter of several circular array and the duplicate gear pinion is corresponding and match with profile of tooth on the duplicate gear pinion one by one.
Further improve:
Described flute profile grinding attachment can be done intermittent the rotation relative to counterdie.
Further improve:
Be equipped with on the described upper bolster and drive the Power Drive Unit that the flute profile grinding attachment rotates.
Further improve:
Power Drive Unit comprises the motor fixing seat that is fixed on the upper bolster, be fixedly connected with the RV reductor in the described motor fixing seat, the power intake of described RV reductor is connected with servomotor, and the clutch end of RV reductor is fixedly connected with the flute profile grinding attachment.
Further improve:
Be provided with in the described counterdie for the alignment pin with 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 equipped with electronic stopper, and electronic stopper is used for the stroke of restriction flute profile grinding attachment, and the excess of stroke is destroyed workpiece when preventing that the flute profile grinding attachment is descending again.
The utility model adopts such scheme, each tooth to pinion in the duplicate gear carries out the while grinding, patrix is finished the grinding process one time, in the backhaul process, rotate to an angle and guarantee in second time process different position on the grinding worm, can guarantee that so repeatedly each tooth grinding is even on the pinion, guarantee grinding accuracy, reduced Grinding Error; The circular runout of having avoided simultaneously 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.
The utility model is described in further detail below in conjunction with drawings and Examples.
