The specific dimensions used in the present example are only for illustrating the technical solution and do not limit the scope of protection of the present invention.
In the prior art, a method for winding a coil by a transformer generally depends on manual winding, which leads to low winding efficiency, and meanwhile, the winding uniformity has a large hidden trouble because the tensioning degree cannot be ensured, so after a plurality of tests, the application provides a transformer winding tensioning device which mainly comprises a base 1, a support 11, a crank arm 2, a lead 4 and a brake cable 5, wherein the support is arranged on the surface of the base, the crank arm is arranged at the top of the support, one end of the lead sequentially penetrates through a wire coil, the support and the crank arm to the winding end of the transformer, and one end of the brake cable sequentially penetrates through the crank arm and the support to the brake end;
the principle on which the structure is based is that a weight hanger 3 is suspended on a crank arm, and the tension of the lead is adjusted by adjusting the balance weight of the weight hanger.
Since it is important to adjust the balance weight of the weight to meet the demand, and the crank arm is used as an intermediate linkage mechanism, the present application provides a preferred embodiment of the crank arm, which comprises a driving arm 21 and a braking arm 22, and one end of the driving arm is connected with one end of the braking arm; the connecting part of one end of the driving arm and one end of the brake arm is separately provided with an assembling hole 26, the top of the bracket is provided with a crank arm shaft 12, the crank arm is fixed on the crank arm shaft through the assembling hole, and the crank arm can rotate around the crank arm shaft; therefore, the sub-crank arm is used as a middle linkage mechanism, the balance of the device can be realized through the adjustment of the posture of the sub-crank arm, and the purpose of self-adjustment is achieved.
A suspended weight shaft 24 penetrates through the other end of the driving arm, one end of the suspended weight shaft extends out of the driving arm, and a rotating wheel 23 is sleeved at one end of the suspended weight shaft extending out of the driving arm; the rotating wheel frame is arranged on a lead which passes through the rotating wheel frame, and the rotating wheel is driven to rotate in the moving process of the lead; the other end of the brake arm is penetrated with a pull wire shaft 25; a weight is suspended on the suspension weight shaft, and the descending direction of the weight faces to the base; a plurality of counterweight steelyards 31 are arranged on the steelyard.
In the above device, the bracket is crucial as a mounting part of the crank arm, and in the preferred embodiment, the top of the bracket is in a U-shaped structure, and two vertical arms of the U-shaped structure are parallel to the base at the same time; the transverse part of the U-shaped structure is provided with an extension frame; a bogie is arranged at the position of the bracket close to the base; a vertical arm close to the brake arm is provided with a wire inlet hole 13, a vertical arm close to the driving arm is provided with a wire outlet hole 14, the extension frame is provided with a wire passing hole 15, and the bogie is provided with a steering hole 16;

In the process of balancing and adjusting the whole device, in order to improve the winding quality, some details are restricted, such as that the wire inlet hole and the wire outlet hole are positioned on the same horizontal line. The wire inlet hole, the wire outlet hole, the wire passing hole and the steering hole can be replaced by the steering wheel.
Finally, the application provides a tensioning method of the tensioning device to clarify the advantages of the transformer winding tensioning device, which specifically includes two situations, when the tensioning force of the transformer winding wire is insufficient, the supporting force of the wire between the wire inlet hole and the wire outlet hole to the rotating wheel on the crank arm is reduced, the wire cannot support the gravity of the weight on the weight through the rotating wheel, the bending degree of the wire is increased, the position of the weight on the main arm is reduced towards the base direction, the brake arm rotates around the crank arm shaft along with the main arm (the crank arm rotates anticlockwise as seen from the view angle in fig. 1), the brake arm is far away from the wire coil hole, the brake wire is tightened, the brake resistance borne by the rotation is increased, the wire tension is reduced, the rotating speed of the wire coil is reduced, because the winding state of the transformer is continuous, the speed of the wire pulled by the transformer end is not changed, the length of the wire between the wire inlet hole and the wire outlet hole is reduced, the bending degree of the wire between the wire inlet hole and the wire outlet hole is reduced, the tension of the lead is increased, and the supporting force of the lead to the crank arm rotating wheel and the pulling force of the lead to the crank arm are balanced again.
When the tension force of a wound wire of the transformer is too large, the bending degree of the wire between the wire inlet hole and the wire outlet hole is reduced, the wire between the wire inlet hole and the wire outlet hole provides an upward thrust force for a rotating wheel on a crank arm, the position of the rotating wheel rises, the rotating wheel drives a lead hanging end of a driving arm to rise, the brake arm rotates around a crank arm shaft along with the driving arm (the crank arm rotates clockwise when seen from a visual angle in fig. 1), the brake arm is closer to the wire outlet hole, the brake wire is loosened, the brake resistance borne by the rotation of the wire coil is reduced, the tension force of the wire is increased, the rotating speed of the wire coil is increased, the speed of the wire pulled by the winding end of the transformer is unchanged, the length of the wire between the wire inlet hole and the wire outlet hole is increased, the bending degree of the wire between the wire inlet hole and the wire outlet hole is increased, the tension force between the wires is reduced, the lead hanging end of the driving arm descends to the base direction, and then balance is achieved again.
In summary, the transformer winding tensioning device provided by the application adjusts the tensioning degree of a transformer winding lead by using the gravity of a counterweight on a weight hanger, the counterweight weight with required weight is placed on the weight hanger, the counterweight weight enables a driving arm of a crank arm to have a downward movement trend away from an assembly hole end, a brake arm and the driving arm are fixed, the downward movement of the driving arm can cause a wire pulling shaft of the brake arm to be away from a wire passing hole, a brake is tensioned, the brake acts on the lead wire coil of the winding transformer, the rotation resistance of the coil is increased, the lead tension is correspondingly increased, and therefore the tensioning degree of the lead is ensured; the whole structure is simple, manual intervention is not needed, and the device is suitable for large-scale popularization.
