Upward, the reference edge of another herringbone bear is downward for the reference edge of wheel.As shown in Figs. 1-2, the reference edge court of the first herringbone bear
On, the reference edge of the second herringbone bear is downward.Using the bottom face for matching herringbone bear as horizontal plane, the first herringbone bear is measured
The corresponding Z of top end faceTop 1Value measures the corresponding Z of top end face of the second herringbone bearTop 2Value.Preferably, pairing herringbone bear is put
It puts down on the table, after being laid flat, centering wheel rim end face run-out.
In step S22, one group of Z is obtained using the method for probe measurementOn、ZUnderValue.For the first herringbone bear 1, along Z
Axis direction mobile probe contacts probe with the ipsilateral side of the upper lower tooth of the datum tooth of the first herringbone bear 1, contact point two
It is a, record the corresponding Z in two contact pointsUpper 1、ZLower 1Value.The second herringbone bear is measured using same method, is recorded
ZUpper 2、ZLower 2Value.
In step S23, pass through calculation formula L=| ZTop-(ZOn+ZUnder)/2 | two centers of pairing herringbone bear are calculated
The distance between plane and corresponding top end face value L1And L2, wherein L1=| ZTop 1-(ZUpper 1+ZLower 1)/2|；L2=| ZTop 2-(ZUpper 2+
ZLower 2)/2|；Pass through L1The central plane C1 for determining the first herringbone bear 1, passes through L2Determine the central plane of the second herringbone bear
C2。
It preferably, further include slightly fixed to pairing herringbone bear using the method for binodal pole school high point before step S2
Position, is accurately positioned again after coarse positioning, is improved efficiency.
In step S3, it is C that the datum level for determining each herringbone bear, which includes: to central plane,1The first herringbone bear, choosing
Taking away from its top end face distance is h1Section be the first section, the datum tooth 11 of the first herringbone bear 1 is corresponding on the first section
Face where the axis of the inner hole 12 of first tooth top center line, the first tooth top center line and the first herringbone bear is the first herringbone bear
1 datum level；It is C to central plane2The second herringbone bear, choose away from its top end face distance be h2Section be the second section,
The datum tooth of second herringbone bear corresponding second tooth top center line, the second tooth top center line and second people on the second section
Face where the axis of word bore is the datum level of the second herringbone bear；Wherein, L1-h1=L2-h2, h1>=0, h2≥0。
Positioning includes, according to the actual conditions of lathe, using end mill head and side milling head in step S3；Workpiece is adjusted, makes the
In ZX plane, the axis of the inner hole 11 of the first herringbone bear 1 is overlapped the datum level of one herringbone bear 1 with Z axis axis；Adjust work
Part makes the datum level of the second herringbone bear in ZX plane, and the axis of the inner hole of the second herringbone bear is overlapped with Z axis axis.Such as
This can realize the corresponding positioning of the first herringbone bear 1 and the second herringbone bear.
The present embodiment additionally provides a kind of processing method for matching herringbone bear, using above-mentioned localization method to pairing people
Word gear is positioned, and is processed after positioning to herringbone bear.Processing to herringbone bear includes the inner hole in herringbone bear
Middle loading copper sheathing adjusts copper sheathing center, location hole is processed on herringbone bear.
By taking the first herringbone bear 1 as an example, the center of adjustment copper sheathing 3 includes: with datum tooth 11 for midpoint, to two sides across corresponding
Pitch circle rod 2 is placed in the tooth socket of tooth pitch, plays table at the first section, and by guarantee two sides pitch circle rod, readings are consistent adjusts copper sheathing
3 centers, 3 center of copper sheathing adjusted is on the first tooth top center line；Equally, for the second herringbone bear, it is with datum tooth
Initial point, to two sides across respective teeth away from tooth socket in place pitch circle rod, play table at the second section, pass through guarantee two sides pitch circle rod
Readings are consistent to adjust copper sheathing center, and copper sheathing center adjusted is on the second tooth top center line.
