Description

Technical Field

[0001] The utility model relates to the technical field of transformer winding equipment, in particular to a winding transposition tool. Background Art

[0002] Transformer conductor winding transposition tools are specialized devices used to change the position of conductors during transformer coil winding. In transformers, conductors are wound around an iron core according to specific patterns to create coils. When winding multiple layers of coils, transposition is necessary between layers to balance the current. In longer coils, transposition is also required between sections to evenly distribute the current.

[0003] Winding needs to ensure the tightness and consistency of the winding. For complex winding shapes, such as S-shaped bends, specially designed winding transposition tools may be required to assist in winding transposition. Traditional winding transposition tools generally weld connecting columns on the base plate and perform winding transposition through two columns. However, this cannot adapt to wires of different thicknesses and winding requirements of different pitches, and has low universality. Utility Model Content

[0004] The utility model aims to provide a winding transposition tool that is suitable for wires of different thicknesses and meets the bending requirements of different pitches to improve universality.

[0005] The utility model provides the following basic solution: a winding transposition tool, comprising: a base plate;

[0006] The bottom plate is provided with a long through hole, and a through hole is further provided along the direction of the long through hole, and the through hole is located on one side of the long through hole;

[0007] A first stud is provided in the long through hole, passes through the long through hole, is connected to a nut at one end, and is threadedly connected to a first nut at the other end; a first annular protrusion is provided in the middle of the first stud, and the diameter of the first annular protrusion is greater than the width of the long through hole;

[0008] A second stud is fixedly arranged in the through hole, one end of the second stud is fixedly arranged in the through hole, and the other end is threadedly connected to a second nut, and the second nut and the first nut are located on the same side of the bottom plate.

[0009] Furthermore, the long through hole is a flat elliptical through hole.

[0010] Furthermore, the width of the middle area of ​​the bottom plate is greater than the width of the two side areas. The middle area is a flat elliptical bottom plate, and the arc areas on both sides are respectively connected to a long strip bottom plate, and the connection points are smooth chamfers.

[0011] Furthermore, the long through hole and the through hole are arranged on the flat elliptical bottom plate.

[0012] Furthermore, a second annular protrusion is provided in the middle of the second stud, and the diameter of the second annular protrusion is larger than the diameter of the through hole.

[0013] The beneficial effects of this solution are as follows: for transformer conductor winding transposition with different thicknesses and different spacing requirements, when using this tool, the first stud passes through the long through hole, and the first annular protrusion is located between the base plate and the first nut, which serves as a limit for the first stud. The first stud is slid in the long through hole to change the distance between the first stud and the second stud. After reaching the appropriate position, the nut is turned to fix the first stud, so that the tool is suitable for the current spacing requirement, wherein the spacing refers to the bending requirement of different wire lengths, that is, how long the wire is bent once. By adjusting the distance between the two studs, the control of the S-bend transposition distance of different gears is met, and it is suitable for different spacing requirements; at the same time, the height of the first nut and the second nut is adjusted to adapt to different thicknesses. The first nut and the second nut are placed between the base plate, and the gap between the nut and the base plate can be adjusted by rotating the two nuts, which can better clamp the transposed wire and avoid lateral torque deformation, making the tool suitable for transposition of wires of various thicknesses. In addition, during operation, the two ends of the base plate are designed as handles, which bear force at the same time, making the operation labor-saving and stable, making the tool easy to operate and use.

[0014] Through the above method, this solution is suitable for wires of different thicknesses and meets the bending requirements of different pitches. It can effectively improve the universality of winding and transposition tools. There is no need to customize several winding and transposition tools according to different thickness and pitch requirements, which effectively saves production costs.

[0025] The bottom plate 1 is provided with a long through hole 2, wherein the long through hole 2 is a flat oval through hole 3, and a through hole 3 is further provided along the direction of the long through hole 2. The through hole 3 is located on one side of the long through hole 2, that is, a through hole 3 is provided on one side of the arc of the long through hole 2. Figure 2 As shown;

[0026] like Figure 3 As shown, a first stud 4 is provided in the long through hole 2. The first stud 4 passes through the long through hole 2 and is connected to a nut 5 at one end. In this embodiment, a cap nut 5 is used and a first nut 6 is threadedly connected to the other end. A first annular protrusion 7 is provided in the middle of the first stud 4, and the diameter of the first annular protrusion 7 is greater than the width of the long through hole 2. When installed, the first annular protrusion 7 is located between the base plate 1 and the first nut 6 as a limit for the first stud 4. The structure of the first stud 4 is as shown in FIG. Figure 4 As shown;

[0027] A first fixing nut 5 is provided between the second nut 9 and the base plate 1 , and the first fixing nut 5 is threadedly connected to the first stud 4 ;

In this embodiment, the second annular protrusion 10 is made to have the same thickness as the first annular protrusion 7, so that the thickness of the first stud 4 and the second stud 8 close to the wire is the same. The structure of the second stud 8 is as shown in FIG. Figure 5 shown.

[0029] The width of the central region of the base plate 1 is greater than that of the side regions.
