Description

Technical Field

[0001] The utility model relates to a high-precision wire winding tooling, belonging to the technical field of tooling. Background Art

[0002] Wire winding tooling is usually used in the automated and precise wire winding process, which can improve production efficiency, enhance wire winding accuracy, reduce human errors, and also reduce the dependence on labor, thereby reducing production costs.

[0003] When making cables made of some wires with relatively high hardness (such as aluminum litz wire, aluminum stranded wire), it is necessary to wind cables with corresponding shapes to adapt to the use of products, and it is required to have high precision on the premise of relatively high hardness itself.

[0004] However, the existing wire winding tooling often fails to achieve the corresponding functions, or the cost of the wire winding tooling is relatively high.

[0005] Therefore, there is an urgent need for a low-cost and high-precision wire winding tooling. Summary of the Invention

[0006] Aiming at the deficiencies of the existing technology, the utility model provides a high-precision wire winding tooling, which can accurately control the distance between adjacent wires, has a good effect on winding wires with relatively high hardness, improves the wire winding efficiency and precision on the premise of low cost, and increases the production capacity of the winding wires used in high-power stators.

[0007] The technical solution of the utility model is as follows:

[0008] A high-precision wire winding tooling for winding wires arranged in a square with intervals, the wire winding tooling includes a fixedly connected wire winding plate and a cover plate, and a wire winding space is formed between the fixed wire winding plate and the cover plate;

[0009] The wire winding plate is provided with a wire inlet hole, and a plurality of lower positioning holes are sequentially arranged from the inside to the outside along the diagonal direction at the four top corners of the wire winding plate. A positioning pin is arranged on the lower positioning hole, so that when the wire passes between two adjacent positioning pins in the top corner direction, the winding direction of the wire changes, realizing the directional winding of the wire.

[0010] Preferably according to the utility model, a spacer block is arranged between the wire winding plate and the cover plate. The size of the spacer block can be adjusted according to the thickness of the wire to be wound to ensure that there is a suitable wire winding space for the wire to pass through.

[0011] Preferably according to the utility model, the cover plate is provided with upper positioning holes, and the positions of the upper positioning holes correspond to those of the lower positioning holes one by one.

[0012] Preferably according to the present utility model, the wire winding tooling further includes a magnetic ring, which is fixed in the upper positioning hole. During the use of the wire winding tooling, the positioning pin sequentially passes through the magnetic ring, the upper positioning hole, and the lower positioning hole. By using the positioning pin and the magnetic ring in cooperation, when the wire needs to turn during the winding process, the positioning pin is inserted into the upper positioning hole and the lower positioning hole, and under the magnetic force of the magnetic ring, the fixing of the positioning pin is facilitated.

[0013] Preferably according to the present utility model, wire grooves are formed on the wire winding board, and the wire grooves that communicate with each other are sequentially formed from the inside to the outside around the center of the wire winding board, and the wire grooves are formed at positions between adjacent positioning pins.

[0014] Preferably according to the present utility model, the wire inlet hole is connected to the wire groove. So that the wire can be wound from the inside to the outside in sequence.

[0015] Preferably according to the present utility model, the wire grooves are arranged in a square pattern on the wire winding board. Thus, wires arranged in a square pattern are obtained.

[0016] Specifically, the cross-section of the wire groove can be changed according to needs, and it can be circular or square.

[0017] The beneficial effects of the present utility model are as follows:

[0018] 1. The wire winding tooling provided by the present utility model is composed of a wire winding board and a cover plate, forming a fixed wire winding space. There is a wire inlet hole on the wire winding board, and there are multiple lower positioning holes at the four top corners along the diagonal direction. Through the positioning pin, the wire can change the winding direction between adjacent positioning pins during the winding process, realizing the precise positioning of the wire, and having a good effect on winding wires with relatively high hardness. On the premise of low cost, the winding efficiency and precision are improved, and the production capacity of the winding wires used for high-power stators is increased.

[0019] 2. An adjustable spacer is arranged between the wire winding board and the cover plate, and the size of the spacer can be adjusted according to the thickness of the wire to be wound, so as to ensure that the wire winding space is suitable for the winding of the wire.

[0020] 3. In order to realize the directional winding of the wire, on the one hand, positioning is carried out through the cooperation of the positioning pin and the magnetic ring. By using the magnetic force of the magnetic ring, the positioning pin can be fixed more conveniently. When the wire winding needs to turn, the cooperation of the positioning pin and the magnetic ring can achieve precise positioning. On the other hand, wire grooves are arranged between different adjacent positioning pins, so that the wire can be smoothly wound from the inside to the outside. At the same time, the wire grooves that communicate with each other are formed on the wire winding board and are arranged from the inside to the outside around the center of the wire winding board, so as to ensure that the wires are arranged in a square shape or other required shapes.
