Description
Technical field
The present invention relates to a kind of hobbing machine frock dedicated on gear-hobbing machine, and in particular to the gear on gear-hobbing machine
Blank wheel clamping device, belongs to machining process equipment technology domain.
Background technology
Using during gear hobbing process method finishing gear, it is necessary to using clamping device by need finish gear be positioned at work
Make on platform, required tooth form is then processed by gear hob.The clamping device used at present mainly includes support, centering
Part and compressing member；The upper surface of support has positioning reference plane, and centering member is generally mandrel；There is positioning hole in the middle part of gear,
The inner surface of the positioning is Internal hole positioning face, and when finishing the gear, from the mandrel of correspondingly-sized, gear is positioned over into branch
On the positioning reference plane of frame so that the positioning hole on gear passes through mandrel, and the centering of gear is realized with this, and clamping element is then used for
Limiting gear relative to workbench rotation and gear relative to centering member in the vertical direction movement.
During actual processing, after prolonged processing, centering member can deform and wear and tear, and cause processing
The accuracy of gear is poor.In addition, also there is following defect in above-mentioned clamping device：When processing various sizes of gear, it need to change not
With the centering member of size, versatility is poor, and changes necessary transporting supports during different centering member, wastes time and energy.In summary,
The problem of how solving above-mentioned in the presence of the processing of gear, it has also become those skilled in the art's technology urgently to be resolved hurrily is difficult
Topic.
The content of the invention
It is an object of the invention to provide a kind of gear blank wheel clamping device on gear-hobbing machine, the clamping device can
The machining accuracy of gear is improved, while also having efficiency higher, workman can be mitigated and divide labor intensity.
The present invention is achieved through the following technical solutions：A kind of described gear blank wheel on gear-hobbing machine clamps dress
Put, it includes base（1）, be fixed on base（1）The platform on top（2）, it is fixed on platform（2）The electromagnetism of upper plane

Mounted in piston cylinder（4）Piston rod top in the middle of, described cone（5）Top be formed with section for square prism（7）,
The prism（7）Force for convenient wrench is installed, in cone（5）Surrounding be uniformly arranged several contract blocks（8）, it is described
Contract block（8）Face inside have and cone（5）The opposite taper angle of periphery, several contract blocks（8）Periphery composition circle
Post, in contract block（8）If periphery on be formed with arterial highway annular groove（10）, in described annular groove（10）Inside it is provided with annular drawing
Spring（9）, the annular extension spring（9）Ensure all contract blocks（8）With cone（5）It will not separate, in its natural state, all contract blocks
（8）The outside diameter constituted is more than magnechuck（3）Intermediate throughholes diameter.
The present invention is such in use, by workpiece（11）Endoporus be socketed in contract block（8）What is constituted is cylindrical
On post, now start piston cylinder（4）Start working, make piston cylinder（4）Piston rod pull downward on cone（5）, due to all
Contract block（8）The outside diameter constituted is more than magnechuck（3）Intermediate throughholes diameter, all contract blocks（8）Can not be with cone
（5）Downwardly together, so, all contract blocks（8）Just to peripheral direction spreading, by workpiece（11）Endoporus is determined in the way of the center of circle is positioned
Position, then starts magnechuck（3）Start working, by workpiece（11）After being completely fixed, it is possible to workpiece（11）Processing.
Beneficial effect：In the present invention, 1, workpiece is fixed by electromagnet, has the advantages that efficiency is higher, 2, pass through
Change different contract blocks（8）To the workpiece of different center bores（11）Centralized positioning is carried out, has the advantages that versatility is higher, 3,
Contract block（8）Outside diameter according to the specific inner hole of workpiece diameter to be positioned customization, have the advantages that positioning precision is higher.
