When changing lathe, a whole set of fixture is unloaded, the bottom adaptation disk and switching pull bar of new machine is changed, then loads onto machine
Bed.
In new construction, without being rigidly connected between ringfeder 2 and chuck body 3, ringfeder 2 easily can be torn open from chuck body 3
Unload down, reduce labor intensity：Pintongs groove is respectively opened respectively in the bottom of ringfeder 2 and stretching set upper side, in use, by ringfeder 2 four
The protruding parts 24 of valve slot structure (such as Fig. 2) is put into ringfeder after being directed at the depressed area 23 of the pintongs slot structure (such as Fig. 3) of expanding sleeve 7
2, it is rotated by 90 °, and it is spacing with holding screw, it can complete to clamp workpiece after oil cylinder drop-down；During dismounting, oil cylinder is unclamped, is exited tight
Determine screw, ringfeder 2 is slightly lifted and is rotated by 90 °, you can propose ringfeder 2.
When changing production, it is not required to dismantle a whole set of fixture from lathe, only need to unloads old ringfeder by upper bar method, load new ringfeder
It can be produced, without centering fixture again, save a large amount of change and produce the time.
New fixture can cover outside diameter and existGear ring class part, can almost meet big at present
Partly in the demand of gear ring processed, even if having new product later, as long as being just not required to throw fixture processed again again within this range, save big
Measure manufacturing cost；As shown in figures 4 a and 4b, the tensile bolt 15 in clamp structure of the present utility model can be with different model machine
Bed, which matches, to be used, and need to only design corresponding adaptation disk and switching pull bar, have very strong versatility, eliminate conventional fixture and exist
Can not be general between different lathes the shortcomings that, simultaneously because reducing the quantity of fixture, also allow for the management of fixture.With AT, subtract
The raising year by year of fast machine yield, the general slotting Fixture for internal tooth of the quick-changing type by power-assisted in the gearbox gear ring for producing high quality, together
When be alternatively other gear-shaping clamps design provide reference.
More than, preferred embodiment only of the present utility model, it is not limited only to practical range of the present utility model, Fan Yiben
The equivalence changes and modification that the content of utility model patent scope is done, it all should be technology category of the present utility model.
