Method, which is characterized in that be adjusted by the method being added gasket on block working face or on oblique guide working face, method is such as
Under:
(1) it is added gasket on the block working face tangent with mandrel
Step 1, it establishes in two side block blocks working face normal thickness difference T1Mapping between disk-like accessory axial direction taper error Δ is closed
System are as follows: T1=L Δ/(l sin θ)；Wherein, the axial width of disk-like accessory is l, and the central span of two oblique guide T-slots is L,
The inclination angle of oblique guide working face is θ；Gauge block group A1, B1, C1 of choose three groups of specifications 1 grade and the above precision are as adjusting pad
Piece, thickness are respectively t0Sin θ, t0, t0sinθ+T1；
Step 2, by B1 group gauge block pad among disk part by performing and high accuracy platform, two groups of gauge blocks of A1 and C1 are padded respectively in two sides
On the working face of block, wherein A1 group gauge block pad one end big in disk-like accessory taper error, C1 group gauge block pad is in disk-like accessory
The small one end of taper error；Disk-like accessory is mounted on mandrel, two side block blocks are fixed on oblique guide, it is ensured that mandrel locating shaft
Section is tangent with oblique guide and two groups of gauge blocks of A1, C1；Then mandrel and disk-like accessory are removed, then removes A1, B1 and C1 tri- simultaneously
Disk-like accessory and mandrel, are finally fixed on oblique guide by group gauge block again, at this point, disk-like accessory bus and round bottom plate working face
Between produce the taper error of Δ；With the progress of polishing, disk-like accessory bus tends to be tangent with round bottom plate working face, most
Realize that the accurate of disk-like accessory axial direction taper error is eliminated eventually；
(2) it is added gasket on oblique guide working face
Step 1, it establishes in two sides oblique guide working face normal thickness difference T2With the mapping between disk-like accessory axial direction taper error Δ
Relationship are as follows: T2=L Δ/(l cos θ)；Gauge block group A2, B2, C2 of choose three groups of specifications 1 grade and the above precision are as adjusting pad
Piece, thickness are respectively t0Cos θ, t0, t0cosθ+T2；
Step 2, by B2 group gauge block pad among disk-like accessory and high accuracy platform, two groups of gauge blocks of A2 and C2 are padded respectively in two skew backs
On the working face of guide rail, wherein A2 group gauge block pad is in the biggish one end of disk-like accessory taper error, and C2 group gauge block pad is in disk class zero
The lesser one end of part taper error；Disk-like accessory is mounted on mandrel, two side block blocks are fixed on oblique guide, it is ensured that mandrel is fixed
Position shaft part and block working face and two groups of gauge blocks of A2, C2 are tangent；Then mandrel and disk-like accessory are removed, then simultaneously remove A2,
Disk-like accessory and mandrel are finally fixed on oblique guide, at this point, disk-like accessory bus and round bottom plate by tri- groups of gauge blocks of B2 and C2 again
The taper error of Δ is produced between working face；With the progress of polishing, disk-like accessory bus becomes with round bottom plate working face
In tangent, the final accurate elimination for realizing disk-like accessory axial direction taper error.
