The utility model embodiment provides a kind of transformer coiling tooling, comprising:
Wire-winding unit, as shown in Figures 1 to 7, wire-winding unit include connecting shaft 1, first flap 2, second flap 3 and third
Baffle 4, first flap 2 offer the first through hole 21 cooperated with connecting shaft 1, and second flap 3 offers and the cooperation of connecting shaft 1
Second through-hole 31, third baffle 4 offer the third through-hole 41 cooperated with connecting shaft 1；
Driving assembly, driving assembly are connect with connecting shaft 1, are rotated for being drivingly connected axis 1；
Wherein, as shown in figure 8, when first flap 2 and second flap 3 are mounted in connecting shaft 1, first flap 2 and
Spacing between two baffles 3 is the first spacing, and the difference of the line footpath of the first spacing and a strand is in the first preset threshold, such as Fig. 9
Shown, when first flap 2 and third baffle 4 are mounted in connecting shaft 1, the spacing between first flap 2 and third baffle 4 is
The difference of the line footpath of second spacing, the second spacing and two strands is in the second preset threshold.
Wherein, first flap 2 can be socketed in connecting shaft 1 by first through hole 21, and second flap 3 can pass through second
Through-hole 31 is socketed in connecting shaft 1, and third baffle 4 can be socketed in connecting shaft 1 by third through-hole 41.First flap 2,
Two baffles 3, third baffle 4 all can be round, perhaps can be it is rectangular or can be irregular shape etc., this is practical newly
Type embodiment is to this without limiting.Driving assembly can be spooling equipment 7, provide driving force for connecting shaft 1, specifically, even
The left side of spindle 1 can be packed into 7 transmission shaft of spooling equipment, and be fastened with hexagon socket head cap screw, when 7 transmission shaft of spooling equipment rotates
When, it drives connecting shaft 1 to rotate, so that the first flap 2 being socketed in connecting shaft 1 and second flap 3 be driven to rotate, or drives
First flap 2 and third baffle 4 rotation being socketed in connecting shaft 1.
Wherein, the first preset threshold can be 0.01mm, perhaps can be 0.1mm or can be 0.5mm etc. arbitrarily
Value.When first flap 2 and second flap 3 are mounted in connecting shaft 1, the first preset threshold can make first flap 2 and second
A strand is placed between baffle 3, and after a strand is placed, which will not be between first flap 2 and second flap 3
There is biggish mobile space, it is preferred that a strand there will not be mobile space between first flap 2 and second flap 3.
Wherein, the second preset threshold can be 0.01mm, perhaps can be 0.1mm or can be 0.5mm etc. arbitrarily
Value.When first flap 2 and third baffle 4 are mounted in connecting shaft 1, the second preset threshold can make first flap 2 and third
