[0028] See also Figure 3 and Figure 4The elastic component 22 includes a first spring 221, a transmission plate 222, a connecting block 223 and a movable rod 224. One end of the first spring 221 is fixedly connected to one side of the fixed plate 21, one side of the transmission plate 222 is fixedly connected to the other end of the first spring 221, one end of the connecting block 223 is fixedly connected to the other side of the transmission plate 222, the other end of the connecting block 223 is fixedly connected to one side of the compression arc plate 24, one end of the movable rod 224 is fixedly connected to one side of the transmission plate 222, and the other end of the movable rod 224 is movably connected to the fixed plate 21 through the movable rod 224 for supporting the transmission plate 222, and the connecting block 223 is used to connect the transmission plate 2 22 and the compression arc plate 24, the expansion and contraction of the first spring 221 can drive the compression arc plate 24 to move through the transmission plate 222 and the connecting block 223, the fixing plate 21 is penetrated with engaging holes 211 on both sides, the engaging component 25 includes a fixing block 251, a second spring 252 and a engaging block 253, one side of the fixing block 251 is fixedly connected to one side of the transmission plate 222, one end of the second spring 252 is embedded and fixedly connected to the other side of the fixing block 251, the inner wall of the engaging block 253 is fixedly connected to the other end of the second spring 252, and the engaging block 253 is embedded and slidably connected to the other side of the fixing block 251 through a slider, the second spring 252 and the engaging block The engaging blocks 253 are symmetrically arranged in two groups, and the fixed blocks 251 and the engaging holes 211 are arranged correspondingly. The extension and contraction of the second spring 252 can drive the engaging blocks 253 to move, and the movement of the pressing arc plate 24 can drive the fixed blocks 251 to move through the connecting block 223 and the transmission plate 222. The extrusion component 23 includes a mounting plate 231, a guide rod 232, an extrusion plate 233 and a third spring 234. One side of the mounting plate 231 is fixedly connected to the other side of the fixing plate 21, and the mounting plate 231 is arranged with two groups at intervals. The guide rod 232 is fixedly arranged between the two groups of mounting plates 231. The upper end of the extrusion plate 233 is connected to the outer surface of the guide rod 232. The surfaces are movably connected, and two groups of extrusion plates 233 are arranged at intervals. The third spring 234 is fixedly arranged between the two groups of extrusion plates 233, and the third spring 234 is movably connected to the outer surface of the guide rod 232. One side of the two groups of extrusion plates 233 is slidably connected with the other side of the fixed plate 21 through a slider, and the two groups of extrusion plates 233 are respectively arranged on both sides of the engaging hole 211. The expansion and contraction of the third spring 234 can drive the two groups of extrusion plates 233 to move. The two groups of mounting plates 231 are used to support the guide rod 232, and the guide rod 232 is used to support the third spring 234, which can prevent the third spring 234 from being severely deformed due to its own weight.

[0029] External force is applied to move and compress the arc plate 24 so that the fixing block 251 is embedded in the engaging hole 211. During this process, the two groups of engaging blocks 253 are squeezed by the engaging hole 211 until the second spring 252 rebounds and drives the engaging block 253 to extend. At this time, the position of the fixing block 251 is fixed, so that the position of the compressing arc plate 24 is also fixed.

The compression arc plate 24 can squeeze the copper wire wound on the winding die, so that the copper wire is tightly attached to the winding die, which can prevent the copper wire from loosening and short-circuiting the oil-immersed power transformer during use. At the same time, the compression arc plate 24 can be fixed by the fixing block 251, the second spring 252 and the engaging block 253, so that the compression arc plate 24 will not affect the installation of the winding die, which is easy to use.

[0030] Embodiment 2:

[0031] See also Figure 5 and Figure 6The winding assembly 4 includes a motor 41, a rotating shaft 42, a fixed component 43 and a driving component 44. One end of the motor 41 is fixedly connected to the inner wall of the fixed housing 3, one end of the rotating shaft 42 is fixedly connected to the output end of the motor 41, and one end of the rotating shaft 42 is rotatably connected to one side of the fixed housing 3. The driving component 44 is arranged inside the rotating shaft 42, and two groups of driving components 44 are arranged. The fixed component 43 is arranged between the two groups of rotating shafts 42, and four groups of fixed components 43 are evenly arranged in an annular shape. The motor 41 is used to drive the rotating shaft 42 to rotate, and the rotating shaft 42 is used to drive The fixing part 43 rotates, and the driving part 44 is used to drive the fixing part 43, so as to adjust the spacing between the four groups of fixing parts 43.

One end of the second electric telescopic rod 441 is fixedly connected to the inner wall of one end of the rotating shaft 42, and one side of the extrusion plate 442 is fixedly connected to the other end of the second electric telescopic rod 441. The extension and retraction of the second electric telescopic rod 441 can drive the extrusion plate 442 to move horizontally. The fixing part 43 includes a support rod 431, a fixing rod 43 2 and a fixed arc plate 433, one end of the support rod 431 is rotatably connected to the other side of the extrusion disk 442, one end of the fixed rod 432 is rotatably connected to the other end of the support rod 431, the lower end of the fixed arc plate 433 is fixedly connected to the upper end of the fixed rod 432, and the outer surface of the rotating shaft 42 is provided with a movable groove for the support rod 431 and the fixed rod 432 to move, and the support rod 431 is symmetrically arranged in two groups. When the two groups of extrusion disks 442 are close to each other, the two groups of extrusion disks 442 will squeeze the two groups of support rods 431, so that the two groups of support rods 431 push the fixed rod 432 to move, Thereby, the fixed rod 432 can drive the fixed arc plate 433 to move toward the outside of the rotating shaft 42. Conversely, when the two groups of extrusion plates 442 move away from each other, the fixed arc plate 433 and the fixed rod 432 will be pulled by the support rod 431 to move toward the inside of the rotating shaft 42. The fixed component 43 also includes a rubber sheet 434 fixedly connected to the outer surface of the fixed arc plate 433. The rubber sheet 434 can increase the friction of the outer surface of the fixed arc plate 433 to avoid slipping between the fixed arc plate 433 and the winding mold. The motor 41 and the two groups of second electric telescopic rods 441 are electrically connected to the single-chip microcomputer.

[0032] The winding mold is put on the outer surface of the rubber sheet 434 of the four groups, and the second electric telescopic rod 441 of the two groups is started to extend by the single-chip computer, so that the extrusion plates 442 of the two groups are close to each other, so that the fixed rods 432 and the fixed arc plates 433 of the four groups are moved to the outside of the rotating shaft 42, and the winding mold can be squeezed and fixed by the extrusion of the fixed arc plates 433 of the four groups. The rubber sheet 434 can prevent the winding mold from slipping during winding, and the installation of the winding mold can be achieved. When the winding mold needs to be disassembled, the second electric telescopic rod 441 of the two groups is started to shrink by the single-chip computer, so that the fixed rods 432 of the four groups are moved to the inside of the rotating shaft 42, and the winding mold can be removed at this time. The operation is simple and easy to use. The spacing between the four groups of fixed rods 432 can be adjusted, and winding molds of different diameters can be fixed, which is convenient for manufacturing coils required for different oil-immersed power transformers.
