Description

Technical Field

[0001] This utility model belongs to the field of generator technology, specifically relating to a winding device for winding coils of a linear generator. Background Technology

[0002] Currently, the coils of linear generators used in trains such as maglev trains all use a "pancake" winding process.

[0003] CN211630042U discloses a coil winding device, including four winding molds and two mounting plates. The coil winding device is mounted on a LIG winding machine and completes coil winding in cooperation with the LIG winding machine. The device includes two mounting plates for docking with the LIG winding machine's shaft. A winding mold is positioned between the two mounting plates. The winding mold has two conical bodies arranged side-by-side for coil winding, and the surface of each conical body has multiple grooves. This invention can complete the winding of four layers and seven turns of enameled wire in one operation with a LIG winding machine, eliminating the need for manual operation and control during the winding process, thus improving the efficiency of the linear generator coil winding process and ensuring the quality of the coils.

[0004] During the entire winding process, existing winding equipment cannot meet the requirements for fully automated winding of this process, and manual intervention is often required to perform operations such as "turning the pancake", which is inefficient. Utility Model Content

Figure 1 and Figure 3 Installation is then carried out. In practical application, the mold core 16 is first manually installed into the mold, and the cylinder moves the mold to the required external dimensions. Then, the connecting shaft 9 in the left-hand rotation drive system drives the mold and mold core 16 to rotate, and the wire laying device moves to lay the wires, discharging the conductors. The first layer of 7-turn conductors is arranged in a barrel shape on the outside of the mold, the second layer of 7-turn conductors is arranged in a disc shape, the third layer of 7-turn conductors is arranged in a barrel shape, and the fourth layer of 7-turn conductors is arranged in a disc shape. The wire laying device is existing technology used to discharge the conductors; it is a structure different from this invention and belongs to existing mature technology, so it will not be further described in this invention.

[0076] Specifically: First, manually press the mold core 16... Figure 3 As shown, the components are installed in mold 14 and mold 2 18. Cylinders 2 12 and 3 13 bring mold 14 and mold 2 18 to the required external dimensions. One end of the wire is fixed to the fixing rod 17.

[0077] After the coil is wound, cylinder 10 ejects the mold core 16, which is then manually removed. The right translational pressing system moves forward and attaches to the outside of the pre-wound coil. At this time, the pressure block at the front end of the pressure mold 21 inserts into the mold gap, supporting the wound coil. Subsequently, the mold shrinks, separating it from the wire. At this point, the center end face of the mold and the end face of the pressure mold clamp the two ends of the wound coil. Then, the right translational pressing device moves forward again, pressing the first 6 turns of the pre-wound coil and the third 6 turns of the pre-wound coil back into the corresponding first turn of the coil, holding this position for a period of time to shape the coil. Finally, the right translational pressing device moves backward, and the shaped coil is manually removed from the mold.
