The output end of the electric push rod 9 contracts and drives the driving column 10 and the two groups of moving blocks 13 to move forward along the track of the slide rail 11. The two groups of moving blocks 13 simultaneously drive the driving shafts 14 on the left and right sides to move respectively. The two groups of driving shafts 14 simultaneously apply the force to the connecting shafts 12 on the left and right sides through the connecting rods 15, so that the connecting shafts 12 on the left and right sides simultaneously drive the first sliders 4 and the limit plates 5 on the left and right sides to move outward along the track of the first slide groove 3.

When the two groups of limiting plates 5 have completed the limiting of the iron core 2, the fastening plate 18 is not in contact with the back of the iron core 2. Then the round rod 21 is rotated clockwise, and the round rod 21 drives the lead screw 20 to rotate clockwise. The lead screw 20 is threadedly connected with the fixing plate 8 and the fixing cylinder 19, so that the lead screw 20 applies a force of forward movement to the fastening plate 18, so that the fastening plate 18 drives the limiting shaft 17 to move forward relative to the fixing plate 8 and the limiting cylinder 16 to limit the iron core 2. When the limiting plate 5 and the fastening plate 18 have completed the limiting of the iron core 2, the iron core 2 can be stacked more accurately.
[0031] S2. Release the limit of the iron core 2 and start the electric push rod 9. The output end of the electric push rod 9 extends to drive the driving column 10 and the two sets of moving blocks 13 to move backward along the trajectory of the slide rail 11, so that the connecting shafts 12 on the left and right sides can simultaneously drive the first sliders 4 and the limiting plates 5 on the left and right sides to move inward.

[0032] In summary, the transformer processing iron core pre-stacking device, by setting the output end of the electric push rod 9 to drive the driving column 10 and the moving block 13 to move along the track of the slide rail 11, the second slider 7 and the fixed plate 8 also move with the movement of the driving column 10, not only the two sets of limiting plates 5 have a certain movement stroke, which can conveniently limit the iron cores 2 of different sizes, but also the fastening plate 18 can conveniently move back and forth in the horizontal direction, thereby greatly improving the stability of the iron core 2 limit, by setting the manual rotation of the round rod 21, the screw 20 can be conveniently rotated with the rotation of the round rod 21, so that the fastening plate 18 can be conveniently It can stably move back and forth in the horizontal direction, so that the fastening plate 18 can limit the iron core 2 more accurately and effectively, further avoiding the phenomenon of the iron core 2 being scattered during the stacking process, and further improving the stability of the iron core 2 stacking process. By setting the first slider 4 and the second slider 7, they can move synchronously. When the limiting plates 5 on the left and right sides and the first slider 4 release the limit on the iron core 2, the second slider 7 can also drive the fixing plate 8, the screw 20 and the fastening plate 18 to move backward along the trajectory of the second slide groove 6, thereby more effectively improving the convenience of releasing the limit of the iron core 2, and thus more effectively improving the convenience of stacking the iron core 2.
