The groove of cloth, a center bridge often is provided with bar groove, center bridge can move in groove；It has been bolted on the base
Gland, is provided with through hole on the gland above center bridge, and a through hole corresponds to one piece of center bridge, passes through spiral shell in each through hole
Bolt is fixed with a steady pin, is connected between steady pin and center bridge by spring；Centering tapered sleeve is provided with the mandrel, it is fixed
The outer surface of heart tapered sleeve and the side of center bridge fit, and its contact area is not less than the 85% of centering tapered sleeve outer surface, center bridge
Opposite side withstand in the endoporus of work gear to be added, it is described centering tapered sleeve top fastening spiral shell has been connected through a screw thread in mandrel
It is female.In the present invention, so contacted by tapered sleeve of feeling relieved with determining the power for being bonded offer and positioning gear between block block by face
The power of transmission is highly stable, and precision is very high；And with multiple center bridges, preferably 6 center bridges, by tooth to be processed
Wheel is positioned and fixed, therefore the gear to be processed after fastening is highly stable.
Above-mentioned three-dimensional multi-functional beveler high-precision positioning fixture, it is preferred that limited block is provided with the center bridge,
The top of limited block is located in the stopper slot of gland, and limited block is merely able to move in stopper slot.Limited block limitation center bridge
Move radially, control the home position of center bridge, ensure the smooth entrance of centering tapered sleeve and exit.
Above-mentioned three-dimensional multi-functional beveler high-precision positioning fixture, it is preferred that the center bridge below steady pin
On be provided with screw fastening tieholen.Locating piece can be locked by the screwed hole and screw fastening tieholen of steady pin using longer bolt
Tightly.
Above-mentioned three-dimensional multi-functional beveler high-precision positioning fixture, it is preferred that the top of the centering tapered sleeve is provided with
Annular groove, the annular groove have been embedded in clamp, and clamp is bolted on clamp nut.It is upward that clamp can limit centering tapered sleeve
Play.Clamp is bolted on clamp nut, and the tapered sleeve that be able to will be felt relieved by clamp when such clamp nut screws out carries
Come up, will not because centering tapered sleeve it is too heavy and caused by exit inconvenience situation.
Above-mentioned three-dimensional multi-functional beveler high-precision positioning fixture, it is preferred that set between the mandrel and centering tapered sleeve
It is equipped with latch, the relative rotation between latch limitation mandrel and tapered sleeve of feeling relieved.
When in use, clamp nut is screwed in downwards for the three-dimensional multi-functional beveler high-precision positioning fixture of the present invention
In mandrel so that centering tapered sleeve is pressed down against, and centering tapered sleeve produces radial load with center bridge, moves radially center bridge, is felt relieved
Block it is mobile can holddown spring, and center bridge withstands the endoporus of work gear to be added so as to have the function that centering；Unclamp fastening
Nut can cause centering tapered sleeve to exit from mandrel, and this when, the elastic force of spring was discharged so that center bridge is radially retracted.
In the present invention, when fixture needs finishing, using the screw of steady pin on gland, practical longer bolt and
Screw fastening tieholen on center bridge locks center bridge, makes center bridge fixed, then is connected with bistrique reconditioning with centering tapered sleeve
Tactile arc binding face.
