Abstract
The utility model relates to a powdered iron core wire wrapping tool fixture. A check block is welded with a large shaft at one end of a lower-pressure central spindle. One end of a column-shaped powdered iron core penetrates through an insulating gasket and is arranged in a blind hole formed in the large shaft of the lower-pressure central spindle and the check block. The insulating gasket is in interference fit with the column-shaped powdered iron core. A dowel is arranged in a blind hole in one end of the column-shaped powdered iron core through a through hole formed in the check block so as to fix the column-shaped powdered iron core on the lower-pressure central spindle. The other end of the column-shaped powdered iron core penetrates through a circular hole of a press plate and is arranged in a core hole of a semi-circular powdered iron core. A U-shaped clamping groove in the upper end of the press plate locks the semi-circular powdered iron core. The column powdered iron core is in transit fit with the semi-circular powdered iron core. The press plate and the semi-circular powdered iron core are in interference fit with the column-shaped powdered iron core. A novel wire winding tool is provided for powdered iron core wire winding, and an ignition coil of a powdered iron core structure is made to fix an enamelled wire tail end and a check line only through the press plate and the insulating gasket. Simple and reliable dowels are used for realizing clamping, so that production cost is reduced, and working efficiency is improved.
Description
Technical field
The utility model relates to a kind of ferrocart core wire winding tool fixture.
Technical background
At present, traditional COP ignition coil uses laminated core mostly.The laminated core of this product is because of complex manufacturing technology, and often molding effect is bad, thereby affects the assembling of ignition coil; And the gap that the lamination between iron core produces also can make the coupling effect of coil exert an influence, and causes output voltage low, and primary current is large, and ignition energy is low, and the fuel consumption of automobile engine is large.For traditional design exist deficiency, by the iron core of lamination change into powder metallurgy structure ferrocart core, one makes fabrication of iron core simple process, and then enhances productivity; Its two eliminations lamination gap, has realized the low current of coil, high output and high-energy.And directly coiling on ferrocart core, although saved low-voltage framework, has reduced cost, the thing followed is how to solve a coiling difficult problem, the one, and it is bad fixing that enamelled wire plays tail head, and the 2nd, do not keep off the easy loose wire of line structure, the 3rd, clamping difficulty, wastes time and energy.Therefore, developing a kind of frock that can solve a powder core coiling difficult problem, is the direction that ignition coil designer makes great efforts.
Summary of the invention
In view of the deficiency that prior art exists, the purpose of this utility model is exactly the ignition coil for ferrocart core structure, and a kind of ferrocart core wire winding tool fixture is provided, and while making to wind the line, frock clamping is easy, reduces production costs, and enhances productivity.
The utility model for achieving the above object, the technical scheme adopting is: a kind of ferrocart core wire winding tool fixture, comprise cylindricality ferrocart core, semicircle ferrocart core, it is characterized in that: also comprise pressing plate, insulating washer, block, low pressure mandrel, pin, the macro-axis of described block and low pressure mandrel one end welds together, one end of described cylindricality ferrocart core is placed in through insulating washer the blind hole forming on low pressure mandrel macro-axis and block, insulating washer and cylindricality ferrocart core are interference fit, the blind hole that the through hole that described pin is provided with by block is placed in cylindricality ferrocart core one end is fixed on cylindricality ferrocart core on low pressure mandrel, the other end of described cylindricality ferrocart core is placed in the core hole on semicircle ferrocart core through the circular hole of pressing plate, the U-shaped draw-in groove of pressing plate upper end pins semicircle ferrocart core, cylindricality ferrocart core and semicircle ferrocart core are interference fits, pressing plate and semicircle ferrocart core and cylindricality ferrocart core are interference fit.
The beneficial effects of the utility model are: this programme provides a kind of novel wire winding tool for ferrocart core winds the line, make the ignition coil pressing plate of ferrocart core structure and insulating washer can realize fixing enamelled wire and play tail head and gear line, utilize simple and reliable pin to realize clamping, reduce production cost, improved operating efficiency.
