It is positioned using holding screw 5 between pressing plate 1 and ontology 7；Holding screw passes through the slot of 1 periphery of the insertion pressing plate of ontology 7
In, limit the relative rotation of pressing plate and ontology 7；The length of the slot of periphery is more than the head sizes that holding screw is inserted into, 1 energy of pressing plate
Enough move up and down.
The butterfly spring ringfeder is located between the disk lower end and the upper end of ontology of pressing plate 1.
Butterfly spring ringfeder 2 be butterfly spring, the multiple radial opening slots of circumference, in addition to an open slot, other open slots
Inner stuffing is oil resistant rubber, is fitted closely with spiral bevel gear endoporus in positioning principle, tensioner using elasticity, is realized high-precision
Degree positioning；An open slot (positioning cotter way 13) on butterfly spring ringfeder is used for across straight pin 3, for limiting butterfly spring
The relative rotation of ringfeder and ontology 7 (or positioning disk).
The positioning disk 4, closely the placement of ontology 7, is sleeved on the periphery of ontology, is fastened with ontology using the second screw 9, wherein
Use cylinder finger setting positioning disk 4 and butterfly spring.
The ontology coordinates with tapered bore of machine tool spindle, and contact area is not less than 80%, is connected with lathe using the first screw 6
It connects, wherein jackscrew and briquetting is installed in the tapped through hole of ontology.
7 lower end periphery of ontology is that (up big and down small) pyramidal structure is inserted into tapered bore of machine tool spindle cooperation.Lathe table top can be with
The lower end ladder table top (pyramidal structure top) of ontology 7 coordinates.Ladder table top is fixed with lathe table top by the first screw 6.
Ontology upper end has step type as a result, i.e. boss is sleeved in butterfly spring；Ladder platform terrace except boss periphery
End face run-out be less than 0.005mm, the circular runout of boss periphery is less than 0.005mm；Stair-step surface roughness reaches 0.4 μ
m。
Calibrating device 12, before processing part, replacement of parts examines gear grinding clamp installation accuracy, protects spring ringfeder.
As shown in Fig. 2, dotted portion, which is spiral bevel gear, installs modes of emplacement.It is radial when the type gear grinding clamp is installed
Bounce is not more than 0.005mm, end surface full jumping 0.005mm little greatly.
Further, 7 material of ontology is 20Cr, and carburizing and quenching is handled, and hardness reaches HRC60, and standard is used with positioning disk 4
