To achieve these goals, the present invention adopts following technical scheme, a kind of special fixture manufacturing collar, comprise columniform plug, there is the locating ring of centre bore and sleeve, locating ring is provided with the locating slot of flat wire, locating ring outside locating slot is provided with baffle plate, and baffle plate is fixed on locating ring by the first screw; Be provided with dextrorotation rectangular thread groove at the middle part of described plug, the left end of plug is arranged in the centre bore of locating ring, and is fixedly connected with by the lock-screw on locating ring, and locating ring is fixed with handle; The right-hand member of plug is arranged in sleeve, and can rotate in sleeve, and sleeve is fixed with locating piece, and the lower end of locating piece has draw-in groove, and described draw-in groove is corresponding with the dextrorotation rectangular thread groove of plug, and described locating piece is fixed on sleeve by the second screw.
The using method of the special fixture of described manufacture collar, comprises the steps:
Step one: by one end bending to 90 ° of flat wire;
Step 2: the curved end of flat wire is positioned in the locating slot of locating ring, covers baffle plate, and by the first screw, baffle plate is fixed on locating ring;
Step 3: the other end of flat wire is positioned in the dextrorotation rectangular thread groove of plug, the left end of plug is penetrated the centre bore of locating ring, and by lock-screw, plug is fixed in locating ring;
Step 4: the right-hand member of plug is positioned in sleeve, the position of adjustment locating piece, makes the top of flat wire enter in the draw-in groove of locating piece, and is fixed on sleeve by the second screw by locating piece;
Step 5: hold tight sleeve for one, another holds tight rotatable handle, makes flat wire advance in the track that the dextrorotation rectangular thread groove of plug and the draw-in groove of locating piece are formed, flat wire is all wrapped on plug;
Step 6: take off sleeve after being wound around, unclamps the first screw, unloads the part after lower baffle plate and processing.
Beneficial effect of the present invention:
When adopting the present invention to be wound around flat wire, the flatness of part after being wound around and the dimensional requirement of part can be ensured, manufacture and process qualified part.In the track that draw-in groove flat wire being installed to dextrorotation rectangular thread groove and locating piece is formed, the route along track is advanced, and owing to there being the restriction of both sides rectangle teeth, the part after winding not easily produces " dish ".
The present invention successfully solves and adopts small-scale flat steel silk to be wound around the yielding technical barrier of collar part, for the development of similar techniques from now on and use provide technical foundation; Its good mouldability and adaptability ensure that the use needs of part, in engineering machinery, obtain applications well.
