223 form that triangle is skewed, and reverse push withstands wheel shaft with wheel shaft, then manipulate the energization of electromagnetic block 233, generate in a ring mutual
The magnetic force of effect, and tightly touched by being bonded block 231 with wheel shaft, then adjust the position of locating piece 6, and its along adjusting sliding rail
7 inwards sliding clamp wheel shaft, and as rotation top plate 4 drives spiral bevel gear at the uniform velocity to rotate, because the lower end of wheel shaft is by fitting block
231 clamp, the lines for the horizontal direction that inner surface is equipped with, so that wheel shaft is rotatable, but can not slide in generation is opposite up and down,
The case where shaking or abjection that cooperation locating piece 6 prevents spiral bevel gear from occurring when rotated.
Problems solved by the invention is the spiral bevel gear roll flute folder of the prior art, because spiral bevel gear roll flute is in roll flute
Rotatable engagement is needed to grind the spiral helicine gear teeth, but the fixture with turning effort can be because the centrifugal force rotated, causes tooth
There are a degree of shakings for wheel, or even slowly deviate from from fixture, influence the precision of roll flute, and the present invention passes through above-mentioned component
Be combined with each other, the present invention passes through the rotatable auxiliary device of reverse ejection that is equipped with, forms three with the wheel shaft of spiral bevel gear
Corner structure tightly clamps spiral bevel gear under the mating reaction of electromagnetic force using the stablizing effect direction ejection wheel shaft of the structure
The wheel shaft of wheel, and by the lines of horizontal direction, keep spiral bevel gear rotatable, but the mutual cunning on vertical direction can not occur
Dynamic, when can effectively prevent rotation, gear guarantees spiral umbrella because of the case where shaking existing for centrifugal force and even deviating from from fixture
Stability of the gear in roll flute, improves the precision of roll flute.
