Description
Technical field
The present invention relates to positioning clamping device field, specially a kind of ring flange stationary fixture.
Background technology
Existing ring flange causes ring flange that play occurs in slotting internal tooth process because slotting power is larger, so as to
Cause random tooth phenomenon, in the clamping process of ring flange, alignment time it is longer, it is low to influence operating efficiency, crudy, and it is pacified
It is not convenient enough that assembly and disassembly are unloaded, and ring flange steadiness during slotting is poor to wait shortcomings.
In order to solve problem above, Chinese Patent Application No. is 201520080691.0 utility model patent, is disclosed
A kind of ring flange gear shaping positioner, including positioning disk, positioning disk top are provided with positioning spigot；Ring flange is placed on the positioning
Inside seam；In the middle part of the positioning disk and both sides are respectively equipped with row and cut groove and U-lag；Briquetting passes through inverted T shaped with the ring flange
Slot bolt is fixed.Ring flange is positioned and is clamped on positioning disk in above scheme, makes ring flange more stable during slotting
Reliably, solve ring flange well and random tooth phenomenon caused by play occurs, while also reduce the clamping of ring flange, centering
Time, substantially increase processing efficiency and crudy.
Above scheme solves deficiency of the prior art by the setting of positioning disk, but above scheme also exist it is following
Problem：Only the side of ring flange is fixed by briquetting for above scheme, and fixed spacing position is less, is carrying out gear shaping behaviour
When making, play still easily occurs for ring flange.
The content of the invention
The invention is intended to provide a kind of to carry out many places to ring flange and fix and consolidate the ring flange of ring flange fixing-stable
Clamp has.

Face tapered bar will contact and offset with contact roller close to one end of contact roller, and contact roller will press two-sided tapered bar to close to the side of tapered bar
To motion, two-sided tapered bar will promote tapered bar to be moved to the direction close to ring flange, and supported flange disk again, strengthen consolidating for push rod
It is set for using, while also achieves the 5th compression so that the stability of ring flange further strengthens.
Further, both sides are provided with symmetrical rubber blanket in locating slot, and negative pressure hole, negative pressure trough and negative pressure are provided with rubber blanket
Hole connects.Rubber blanket is more soft and has certain elasticity, more preferably more closely can be bonded with ring flange wall, sealing is more
Good, ring flange can be carried out absorption fixation by rubber blanket well by negative pressure hole so that outside air is not easily accessible negative pressure trough
It is interior, so as to ensure the state of negative pressure in negative pressure trough, it ensure that suction-operated of the negative pressure trough to ring flange.
Further, drive mechanism is cylinder.It the setting of cylinder, can drive compressor arm is upper and lower reciprocally to move, realize pressure
The automatic operating of tight bar.
Further, roller is installed, compressor arm is mutually against in the wedge groove of piston by roller on the wedge surface end of compressor arm.Rolling
The setting of wheel so that the sliding friction change rolling friction between compressor arm and piston, reduce between compressor arm and piston
Rubbing action, so as to extend the service life of compressor arm and piston.
