Then, the bevel gear A drives the rotating shaft to rotate through the driving mechanism, and the rotating shaft drives the two groups of winding posts A to rotate around the rotating shaft. At the same time, the two groups of winding posts A drive the two groups of winding posts B to rotate. When the two groups of winding posts A and two groups of winding posts B rotate, the two wires wound on the two groups of winding posts A and two groups of winding posts B are wound onto the two groups of winding posts A and two groups of winding posts B respectively to form a uniform winding mechanism. coils; when winding coils on two sets of winding posts A, rotate the lead screw, and the lead screw adjusts the distance between the two sets of winding posts A through two sets of sliders until the distance between the two sets of winding posts A matches the diameter of the wire to be wound, then wind the wire around the two sets of winding posts A, and then rotate the two sets of winding posts A around the axis of the rotating shaft to complete the winding; when winding coils on two sets of winding posts B, first loosen the bolt A, and then adjust the distance between the two sets of winding posts B by moving the slider until the distance between the two sets of winding posts B matches the diameter of the wire to be wound, then tighten the bolt A to fix the slider, and then wind the coils on the two sets of winding posts B.

[0038] Two vertical plate groups are symmetrically arranged at the bottom of the lifting plate 9. The vertical plate group includes two vertical plates 91. The distance adjustment component 7 includes a first double-headed screw 71. The outer surfaces of the first double-headed screw 71 are provided with threads of opposite rotation at both ends.

When the upper passive gear 75 rotates, the upper passive gear 75 drives the upper rotating shaft 74 and the upper driving bevel gear 76 on the upper rotating shaft 74 to rotate. The upper driving bevel gear 76 drives the upper passive bevel gear 73 to rotate. The upper passive bevel gear 73 drives the first double-headed screw 71 to rotate, thereby allowing the two adjustment plates 72 in the same distance adjustment assembly 7 to move closer to or farther away from each other.

[0039] A second cylinder 10 is fixedly provided on the top of the lifting plate 9. The output end of the second cylinder 10 passes through the lifting plate 9 and is fixedly connected to a fixed block 11. A servo motor 12 is fixedly provided on the front side of the fixed block 11. An upper driving gear 121 and a lower driving gear 122 are fixedly sleeved on the output end of the servo motor 12.

[0040] When it is necessary to adjust the distance between the two lower winding posts 52 and the upper winding post 54 in the same movable box 2, the first cylinder 13 is started, and the output end of the first cylinder 13 drives the lifting plate 9 to drop vertically to the specified position. The adjusting plate 72 contacts the corresponding moving bar 53. During the vertical descent of the lifting plate 9, the locking control component 8 can cooperate with the corresponding locking component 6 to unlock the corresponding moving bar 53. Then the second cylinder 10 is started, and the output end of the second cylinder 10 drives the fixed block 11 to drop vertically. The fixed block 11 drives the servo motor 12 and the upper driving gear 121 and the lower driving gear 122 on the servo motor 12. The whole body descends vertically until the lower driving gear 122 meshes with the lower driven gear 46, and the servo motor 12 is started. The output end of the servo motor 12 drives the upper driving gear 121 and the lower driving gear 122 to rotate, and the lower driving gear 122 drives the lower driven gear 46 to rotate. The transverse drive component 4 operates to make the two moving components 5 move closer to or away from each other, thereby adjusting the distance between the two lower winding posts 52 and the two upper winding posts 54. When the transverse drive component 4 operates, it can drive the locking control component 8 to operate, and the rack 84 follows the corresponding moving component 5 to move in the same direction at the same time, and the second cylinder 10 is started. The output end of the second cylinder 10 drives the fixed block 11 to rise vertically, and the fixed block 11 drives the servo motor 12 and the upper driving gear 121 and the lower driving gear 122 on the servo motor 12 to rise vertically as a whole, until the upper driving gear 121 is engaged with the upper passive gear 75, and the servo motor 12 is started. The output end of the servo motor 12 drives the upper driving gear 121 and the lower driving gear 122 to rotate, and the upper driving gear 121 drives the upper passive gear 75 to rotate, so that the distance adjustment component 7 is operated, so that the two adjustment plates 72 in the same distance adjustment component 7 can approach each other or move away from each other. When the two adjustment plates 72 are close to each other, When the two movable bars 53 in the middle are squeezed, the tension spring 55 is stretched. When the two adjustment plates 72 move away from each other, the two upper winding posts 54 move away from each other under the tension of the corresponding tension spring 55 until the designated positioning port 531 is on the internal axis of the lower winding post 52. Then, the distance between the two upper winding posts 54 is adjusted for the second time, so that the distance between the two upper winding posts 54 and the two lower winding posts 52 in the same movable box 2 finally reaches the predetermined distance. Then, the lifting plate 9 is raised vertically, and the locking control component 8 cooperates with the corresponding locking component 6 again to lock the corresponding movable bar 53.

During the vertical movement of the lifting plate 9, the rack 84 can be meshed with the corresponding matching gear 64.

[0043] When the lifting plate 9 descends, it drives the rack 84 to descend synchronously, and the rack 84 is meshed with the corresponding matching gear 64, so that the matching gear 64 rotates, and the matching gear 64 drives the longitudinal threaded rod 62 to rotate, so that the longitudinal slider 63 moves longitudinally in the direction close to the matching gear 64 until the longitudinal slider 63 disengages from the inside of the lower winding column 52, releasing the locking state of the moving bar 53, so that the moving bar 53 can move; when the transverse drive assembly 4 is running, the driving threaded rod 41 drives the lower rotating gear 43 to rotate, and the lower rotating gear 43 drives the upper rotating gear 88 to rotate, and the upper rotating gear 88 drives the transverse rotating shaft 86 and the lower pulley 87 on the transverse rotating shaft 86 to rotate, and the lower pulley 87 drives the upper pulley 85 to rotate through the second belt 89, and the upper pulley 85 drives the second double-headed screw 81 to rotate, so This causes the two displacement blocks 83 in the same locking control component 8 to move, and then the displacement blocks 83 and the rack 84 follow the corresponding moving components 5 to move in the same direction at the same time, so that the rack 84 and the corresponding matching gear 64 always remain in meshing relationship; when the lifting plate 9 rises vertically, the lifting plate 9 descends and drives the rack 84 to rise synchronously, causing the matching gear 64 to rotate in the opposite direction, and the matching gear 64 drives the longitudinal threaded rod 62 to rotate in the opposite direction, causing the longitudinal slider 63 to move longitudinally away from the matching gear 64 until the longitudinal slider 63 passes through the designated positioning port 531 and the longitudinal slider 63 passes through the lower winding column 52 to lock the moving bar 53. It should be noted that before the moving bar 53 is locked, the adjustment plate 72 is always in conflict with the moving bar 53 to prevent the moving bar 53 from moving before it is locked.
