Description
Technical field
The present invention relates to positioning clamping device field, specially a kind of flange gear shaping fixture.
Background technique
Existing ring flange causes ring flange that play occurs in slotting internal tooth process since slotting power is larger, thus
Lead to random tooth phenomenon, in the clamping process of ring flange, alignment time it is longer, it is low to influence working efficiency, processing quality, peace
It is not convenient enough that assembly and disassembly are unloaded, and ring flange stability during slotting is poor to wait shortcomings.
In order to solve problem above, the utility model patent that Chinese Patent Application No. is 201520080691.0, discloses
A kind of ring flange gear shaping positioning device, including positioning disk, positioning disk top are equipped with positioning spigot；Ring flange is placed on the positioning
Inside seam allowance；In the middle part of the positioning disk and two sides are respectively equipped with row and cut slot 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, keeps ring flange more stable during slotting
Reliably, it has well solved ring flange and random tooth phenomenon caused by play occurs, while having also reduced the clamping of ring flange, centering
Time substantially increases processing efficiency and processing quality.
Above scheme solves deficiency in the prior art, but there is also following for above scheme by the setting of positioning disk
Problem: above scheme only passes through briquetting and the side of ring flange is fixed, and the position of fixed limit is less, is carrying out gear shaping behaviour
When making, ring flange is still easy to happen play.
Summary of the invention
The invention is intended to provide a kind of multimode that can carry out ring flange fix and insert the flange of ring flange fixing-stable
Tooth fixture.
Flange gear shaping fixture in this programme, including rack, rack are equipped with positioning disk, are provided with positioning on positioning disk
Slot, symmetrical two pressing devices centered on locating slot are provided on positioning disk, and pressing device includes being used for supported flange disk

Plug, first piston and water storage tank far from being connected with spring between the one side wall of cold air path, water storage tank far from cold air path one
Be equipped on side wall for heater and close for cold air case the second button.
The principle of this programme are as follows: rack is used to support entire stationary fixture, and positioning disk can be fixed and prop up to ring flange
Support will need the ring flange processed to be put into the locating slot of positioning disk, and first the position of ring flange is fixed for locating slot, pressure
Tight device can carry out multidirectional fixation to ring flange, start driving mechanism, and driving mechanism drives compressor arm to the side close to ring flange
To movement, compressor arm is moved with dynamic pressure plate to the direction close to ring flange, and pressing plate will be contacted with water pocket, and pressing plate will make water pocket to calmly
It is swung on the Pan Bi of position, until clamping water pocket between pressing plate and positioning disk wall, water pocket will be deformed, and the water in water pocket will be extruded to
It in hole for water spraying, and is ejected on ring flange from hole for water spraying, compressor arm also compresses ring flange, realizes to the primary solid of ring flange
It is fixed；While water pocket is compacted, the first button will be also pressed, opens for cold air case, will be provided into cold air path for cold air case
Cold air, temperature gradually decreases in the positioning disk wall around locating slot, when temperature is down to zero it is following after, compressor arm and ring flange it
Between water will freeze, and ring flange is fixed again, realizes secondary fixation；By the combination of the above secondary fixation,
Realize the function of pressing device multimode fixed flange；Temperature reduction in another aspect cold air path can also be in ring flange
When carrying out Gear Shaping, cool down to ring flange.
While cold air path temperature reduces, the temperature in water storage tank will pass to cold air path by heat conductive rod, store up
Temperature in sink reduces, and until the temperature in water storage tank is reduced to subzero, the water in water storage tank gradually becomes from liquid
Solid-state Cheng Bing, ice become larger relative to the volume of water, and first piston will be pushed to move to the direction close to the second button, Zhi Dao
One piston touches the second button, closes for cold air case, and heater is opened, and heater heats cold air path and water storage tank, so that pressure
The ice in ice and water storage tank between tight bar and ring flange becomes water, starts driving mechanism, so that compressor arm resets, completes
Gear shaping operation to ring flange, takes out ring flange.
Compared with prior art, this programme has the beneficial effect that setting of this programme by pressing device, so that entire folder
While tool can be fixed ring flange, icing fixed operation is carried out, the combination of secondary fixation realizes fixture to method
