Description
Technical field
The utility model relates to gear-hobbing machine fixture components, more particularly, to a kind of dedicated chuck of high speed gear hobber.
Background technique
Scroll chuck is also known as scroll chuck, its three claws be linkage, have it is convenient for mounting and clamping, can from
The advantages of dynamic centering；But scroll chuck generates coaxiality error, causes to process in gear hobbing with precision will be greatly reduced later long
When there is shake knife and mandrel locating bias phenomenon, to cause Product Precision bad, there is surface roughness in the gear processed
Situations such as unqualified or circular runout is bad；When in addition being processed using scroll chuck compared with miscellaneous goods, lathe cutter saddle is easy to appear dry
It relates to, leads to not process；Therefore chuck (the i.e. manual four paws single action card of lathe is used on existing high speed gear hobber more
Disk), structure includes a disk body, four vertical screw rods of the equalization setting on disk body, and the card driven respectively by each screw rod
Pawl (four) compositions, claw be the terraced structure highly gradually decreased outward from disk body center, and when work passes through four lead screws
Four claws, each claw independently moving, although the position by adjusting four claws being capable of the various rectangles of clamping are driven respectively
Or irregular workpiece, but the card access surface of claw and workpiece is plane contact, when with the clamping gear on gear-hobbing machine, is easy damage
Hurt bore, and can not self-centering, lead to not the quick-clamping for realizing same model high-volume gear.
Summary of the invention
The utility model aim is to provide the dedicated four paws of high speed gear hobber that a kind of gear clamping is convenient, positioning accuracy is high
Chuck.
To achieve the above object, the utility model can take following technical proposals:
The dedicated chuck of high speed gear hobber described in the utility model, including disk body, the disk body upper surface offer
Cross chute is provided with four groups of lead screws in the cross chute, and there are four claw, four institutes for setting in cross chute
Claw is stated to connect with lead screw transmission described in four groups respectively；The claw is the L-type structure of transverse arm outwardly, the trailing arm lateral surface of claw
For arcuate structure, transverse arm length is less than the root circle of gear away from the thickness of inner hole wall；Pass through in the trailing arm upper end of the claw
Screw fitting is fixed with inverted L shape sheet copper, and the stringer board of the inverted L shape sheet copper fits with the trailing arm lateral surface of the claw,
The circular cone counterbore that cone angle is 60 ° is offered at the bottom center of the disk body.
The arcuate structure of the claw trailing arm lateral surface is adapted to the fitting of the inner hole wall of gear.
The utility model advantage is that structure is simple, easy to operate.The special jaw of L-type structure makes itself and work gear to be added
Contact area increase, to improve the supporting power of claw；The arcuate structure of claw trailing arm lateral surface is interior with work gear to be added
Hole adaptation fitting, can preferably fix gear, and cooperation fitting is fixed on the inverted L shape sheet copper of trailing arm upper end, prevents card
Hurt bore, moreover it is possible to guarantee the machining accuracy of gear；60 ° of cone angle of circular cone counterbore can be realized automatically at disk body bottom center
Centering, it is convenient to be attached assembly with lower part tooling.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the top view of Fig. 1.
Specific embodiment
As shown in Figure 1, 2, the dedicated chuck of high speed gear hobber described in the utility model, including disk body 1, on disk body 1
Surface offers cross chute 2, and four groups of lead screws are provided in cross chute 2, and there are four cards for setting in cross chute 2
Pawl 3, four claws 3 are connect with four groups of lead screw transmissions respectively；Claw 3 is the L-type structure of transverse arm outwardly, on the transverse arm for making claw 3
Surface can have bigger area and Gear Contact to be processed, to improve the supporting power of claw, in addition transverse arm length is less than tooth
Thickness of the root circle of wheel away from inner hole wall, hobboing cutter will not hurt claw 3 when guaranteeing gear hobbing；The trailing arm lateral surface of claw 3 be with
The arcuate structure of the inner hole wall fitting adaptation of gear, can preferably fix gear, realize the fast quick-mounting with model gear
It unloads；Inverted L shape sheet copper 5, the stringer board and claw 3 of inverted L shape sheet copper 5 are fixed with by the fitting of screw 4 in the trailing arm upper end of claw 3
Trailing arm lateral surface fit, using the flexible nature of copper, cooperate the arcuate structure of 3 trailing arm lateral surface of claw, can be effective
Card is prevented to hurt bore；The circular cone counterbore 6 that cone angle is 60 ° is offered at the bottom center of disk body 1, it is automatic fixed to can be realized
The heart, it is convenient to be attached assembly with lower part tooling.
The utility model is very suitable to high-volume and works with the gear hobbing of model gear, places gear to be processed when use
In on 3 transverse arm of claw, the trailing arm of four claws is located in the inner hole of gear, then adjusts separately lead screw, makes 3 clamping teeth of claw
Wheel can carry out the gear hobbing work of gear later.
