Rotate around rotary shaft, thus adjust the laser direction that laser machine is launched.In the present embodiment, described laser instrument is internally integrated and expands
Collimation camera lens, it is provided that the high depth of parallelism, low divergence laser.
The tooth surface equation of described enveloping worm 16 is
Wherein, A=-cos αdCos θ, B=-cos
αd sinβsinθ±sinαdCos β, C=-cos αd cosβsinθ±sinαdSin β, D=rd cosθ-a0, E=rd sinβ
sinθ±0.5SaCos β, F=-rd cosβsinθ±0.5Sa cosβ,nx=sin αd cosθ,ny=sin α sin θ sin β+
cosαdCos β, nz=-sin αd sinθcosβ+cosαdSin β, αdFor processing the emery wheel profile angle of enveloping worm 16, rdFor adding
The grinding wheel radius of work enveloping worm 16, SaFor processing the emery wheel top width of enveloping worm 16, β is that the emery wheel of processing enveloping worm 16 inclines
Oblique angle,Corner for worm screw.
Formula has three variablees to be determined: tool rest angle of revolution in the course of processingMeshing point P is along emery wheel side surface direction
From distance u of wheel top grinding and the grinding wheel spindle cross section at meshing point P place and iaAngle theta.
One is selected in the operation interval of processingValue, the then value of a selected u, root in fully teeth height numerical range
Variable θ can be drawn according to the tooth surface equation of enveloping worm 16.The tooth surface equation of enveloping worm 16 is solved as Newton iteration: by processing
Practical situation may determine that, the θ value of the tooth surface equation meeting enveloping worm 16 is near 180 °, therefore at 170 ° to 190 °
In the range of obtain one group of tooth surface equation meeting enveloping worm 16ValueWill
ArriveSubstitute intoFormula
In I.e. can get a contact point on enveloping worm 16.Corresponding to same
IndividualValue, takes different values by u in fully teeth height scope, can be contacted different θ values by conjugate condition equation successively, thus can
Obtain multiple contact point, contact point is connected and can form a contact line.Finally corresponding to differentValue, can obtain difference
Contact line, these contact lines just constitute worm spiral face.
