The horizontal moving component 5 that slides with the rotating component 4 is installed on the upper part of the lifting platform 2, and the right end of the horizontal moving component 5 is connected to the adaptive expansion component 6.
[0028] When the device is used to wind the coil, first, according to the internal diameter of the coil, the size of the adaptive expansion component 6 is adjusted, and then the coil to be wound is put on the adaptive expansion component 6, and the end of the copper wire wound on the winding drum 3 is placed on the coil, and then the adaptive expansion component 6 is driven by the rotating component 4 to start rotating, and the winding on the coil is started. At the same time, the horizontal moving component 5 is controlled to move horizontally repeatedly so that the copper wire can be evenly wound on the coil. When the copper wire on the winding drum 3 decreases or increases, the winding drum 3 can be driven by the lifting platform 2 to move upward or downward so that the distance between the copper wire on the winding drum 3 and the coil is kept consistent, so that the coil can be wound under the same tension. After the coil is wound, the rotating component 4 and the horizontal moving component 5 are controlled to stop working, and the copper wire is cut and the wound coil is removed.
[0029] like Figure 3 As shown, the rotating component 4 includes a guide cylinder 41, a large gear 42, a motor I 43 and a pinion 44. The guide cylinder 41 is fixedly connected to the top of the lifting platform 2 by bolts, and the large gear 42 is coaxially mounted on the left side of the guide cylinder 41. The lifting platform 2 below the large gear 42 is fixedly connected to the motor I 43 by bolts, and the output shaft of the motor I 43 is connected to the pinion 44 through a coupling, and the pinion 44 is meshed with the large gear 42.
[0030] The horizontal moving component 5 includes a sliding shaft 51, a cylinder 52 and a connecting plate 53. The sliding shaft 51 is coaxially rotatably connected in the guide cylinder 41.

The wedge block I 65 is connected to the middle of the surface, the threaded rod 67 is rotatably connected in the connecting column 61, the threaded rod 67 passes through the connecting column 61 and is connected to a handwheel at the right end, a circle of the sliding groove 66 is opened in the middle of the connecting column 61, the middle of the threaded rod 67 is threadedly connected to the wedge blocks II 68 of the same number as the wedge blocks I 65, the wedge blocks II 68 pass through the sliding groove 66, and the inclined surface of the wedge block II 68 fits with the inclined surface of the wedge block I 65.
[0032] When winding the coil, first, according to the diameter of the coil, the threaded rod 67 is rotated by the hand wheel, thereby driving the wedge block II 68 to move to the right, thereby driving the wedge block I 65 to expand outward, so that the arc strip 63 expands outward, the spring 62 is stretched, and when the arc strip 63 expands outward to the required width, the threaded rod 67 is stopped from rotating, and then the coil is sleeved on the outside of the arc strip 63, and then the motor I 43 is controlled to rotate, driving the small gear 44 to rotate, and then driving the large gear 42 to rotate, and then driving the slide shaft 51 to rotate, thereby driving the connecting column 61 and the components thereon to rotate, so that the coil rotates and starts winding. During the process of winding the coil, the cylinder 52 is controlled to extend or shrink, driving the slide shaft 51 to move first to the right and then to the left, so that the adaptive expansion component 6 moves left and right repeatedly, so that the copper wire can be evenly wound around the coil. After the coil is wound, the cylinder 52 is controlled to reset, and the motor I 43 is controlled to stop working.

[0035] Before winding the coil, the copper wire is passed through the guide wheel II 83 below the mounting plate 71, the slotted hole on the mounting plate 71 and the limit ring 82 on the guide wheel I 81 in sequence, so that the copper wire between the coil and the guide wheel I 81 is in a vertical state, thereby improving the effect of coil winding. After the coil is wound, the motor II 74 is controlled to rotate counterclockwise, driving the transmission gear 75 on the front side to rotate counterclockwise, and then driving the transmission gear 75 on the rear side to rotate clockwise, and driving the blades 73 to move closer to each other through the rotating shaft 72 to cut the copper wire, and then controlling the motor II 74 to rotate clockwise, driving the blades 73 to separate and reset, and then controlling the motor II 74 to stop working.
