The clamping assembly 4 also includes a bidirectional screw rod 47 rotatably connected to the inner side of the mounting frame 2, and the lower end of the bidirectional screw rod 47 is rotatably connected to the support table 1. One side of the first rotating rod 41 and the second rotating rod 42 is respectively rotatably connected to the first threaded block 45 and the second threaded block 46, and the first threaded block 45 and the second threaded block 46 are respectively threadedly connected to the outer side of the bidirectional screw rod 47, and the inner side of the mounting frame 2 is fixedly connected to a guide rod 48, and the first threaded block 45 and the second threaded block 46 are both slidably connected to the guide rod 48.

[0024] Specifically, by rotating the bidirectional screw rod 47 and then cooperating with the guide rod 48, the first threaded block 45 and the second threaded block 46 can be easily moved relative to each other. At this time, the first rotating rod 41 and the second rotating rod 42 are respectively rotated on the outside of the first threaded block 45 and the second threaded block 46, so that the two connecting blocks 43 can be easily pushed to push the corresponding two clamping plates 44 to clamp multiple core bodies 6 at the same time, thereby conveniently making the multiple stacked core bodies 6 neatly arranged front and back.

[0025] In this embodiment, the inner sides of the first threaded block 45 and the second threaded block 46 are respectively fixedly connected with a rotating shaft 411, and the first rotating rod 41 and the second rotating rod 42 are respectively provided with a circular hole 412 that matches the two rotating shafts 411. The first rotating rod 41 and the second rotating rod 42 are respectively rotatably connected to the corresponding rotating shaft 411 through the circular holes 412.

[0026] Specifically, through the rotational cooperation between the rotating shaft 411 and the circular hole 412 , the first rotating rod 41 and the second rotating rod 42 can be conveniently rotated on the outsides of the first threaded block 45 and the second threaded block 46 respectively.

[0027] In this embodiment, the lower end of the bidirectional screw rod 47 is fixedly connected to the slave cone wheel 49, which is arranged at the lower end of the support table 1.

[0033] It should be noted that the present invention is an automatic stacking device for transformer cores. The user places multiple core bodies 6 on the outside of the two limit plates 8 in turn. At this time, the design of the two limit plates 8 and the vertical plate 7 can easily make the two sides of the multiple core bodies 6 neat. However, the front and rear ends of the multiple core bodies 6 stacked together are uneven. Then, the dual-axis motor 11 is started, and the front and rear output ends of the dual-axis motor 11 will drive the corresponding main cone wheel 410 to rotate. The rotation of the main cone wheel 410 will drive the rotation of the slave cone wheel 49. The rotation of the slave cone wheel 49 will drive the bidirectional screw rod 47 to rotate. Then, through the cooperation of the guide rod 48, the relative movement of the first threaded block 45 and the second threaded block 46 can be easily achieved. At this time, through the rotation cooperation of the rotating shaft 411 and the round hole 412, It is convenient to realize the rotation of the first rotating rod 41 and the second rotating rod 42 on the outside of the first threaded block 45 and the second threaded block 46 respectively, and then the first rotating rod 41 and the second rotating rod 42 are rotatably connected to the connecting block 43, so that the two clamping plates 44 can be conveniently clamped on multiple iron core bodies 6 at the same time, and then the multiple stacked iron core bodies 6 can be conveniently made neatly arranged front and back. When the stacking is completed, the dual-axis motor 11 is started in reverse, so that the two clamping plates 44 can be moved away from the iron core body 6. At this time, the short cylinder 9 is started, and the output end of the short cylinder 9 will drive the support plate 10 to move upward, so that the support plate 10 can drive multiple neatly stacked iron core bodies 6 to move upward, thereby facilitating the staff to transfer the neatly stacked iron core bodies 6, which is more practical.
