The transformer iron core superposition device convenient to operate has the working principle that:
firstly, the gap between a pair of slide bottom plates 31 is adjusted according to the size of the iron core 40, and the method is as follows: synchronously starting a pair of starting cylinders 21 to drive an electromagnet 22 to penetrate through a left guide block 311 and a right guide block 311 to be contacted with an attraction block 312, then electrifying the electromagnet 22 to generate magnetism, so that the electromagnet 22 attracts the attraction block 312, then synchronously starting a pair of starting cylinders 21 to drive the attraction block 312 to be synchronously far away until the size of an iron core 40 is met, then screwing a support rod 32 into a corresponding limit threaded hole 310, then unscrewing a bolt 325 to take down an upper limit plate 324, placing the iron core 40 from top to bottom in sequence, enabling a vertical sliding limit groove 400 of the iron core 40 to penetrate through the support rod 32 and abut against an upper support ring 323, and descending the upper support ring 323 along with the increase of the iron core 40; then the electromagnet 22 loses magnetism, so that the support rod 32 clamps the iron core 40 under the action of the tension spring 24, and finally the upper limiting plate 324 is installed at the top of the support rod 32 through the bolt 325, so that the iron core 40 is conveniently and accurately superposed, and meanwhile, the iron core 40 is arranged in a suspended mode, so that the follow-up procedures are convenient to carry out.
