[0018] The present utility model provides a nanocrystalline transformer for a high-frequency welding machine as Figures 1-5 shown, which includes a plurality of magnetic cores 1. The outer sides of the magnetic cores 1 are wound with a primary winding 2 and a secondary winding 3. A card slot 4 is formed on the front side of the magnetic core 1. Two groups of limiting plates 5 are arranged on the front side of the card slot 4, and each group of limiting plates 5 has two. An arc connecting bar 6 is connected to the rear side of the magnetic core 1, and the other side of the arc connecting bar 6 is connected to a card plate 7. The card plate 7 corresponds to the limiting plate 5. By inserting the card plate 7 on one magnetic core 1 into the card slot 4 on another magnetic core 1 and rotating one of the magnetic cores 1, the magnetic core 1 drives the arc connecting bar 6 to rotate, and the arc connecting bar 6 drives the card plate 7 to rotate, and the two card plates 7 are inserted into the two groups of limiting plates 5. The position of the card plate 7 is limited by the limiting plate 5, so that the two magnetic cores 1 are connected to each other, improving the connection stability of two adjacent magnetic cores 1. A pressing assembly 8 is arranged on the outer side of the magnetic core 1.
[0019] The side walls of multiple said cores 1 are connected with L-shaped mounting plates 9, and mounting holes are formed on the surfaces of the L-shaped mounting plates 9, which can facilitate the installation of multiple cores 1.
[0020] The pressing component 8 includes a connecting portion 81, a pressing portion 82 and a locking portion 83. The connecting portion 81 is connected to the outside of the core 1. A first threaded hole is formed on the surface of the locking portion 83, and a bolt 84 is threadedly connected in the first threaded hole. A second threaded hole corresponding to the bolt 84 is formed on the outside of the core 1. By clamping the primary winding 2 and the secondary winding 3 into the pressing portion 82 and rotating the bolt 84 to screw the bolt 84 into the second threaded hole on the core 1, the primary winding 2 and the secondary winding 3 are pressed by the pressing portion 82, and thus the winding stability of the primary winding 2 and the secondary winding 3 can be improved.
[0021] High-temperature resistant tapes are wound around the outside of the primary winding 2 and the secondary winding 3, which can facilitate improving the high-temperature resistance effect of the primary winding 2 and the secondary winding 3.
[0022] The working principle of the present utility model:
[0023] By clamping the clamping plate 7 on one core 1 into the clamping groove 4 on another core 1 and rotating one of the cores 1, the core 1 drives the arc-shaped connecting bar 6 to rotate, and the arc-shaped connecting bar 6 drives the clamping plate 7 to rotate. The two clamping plates 7 are clamped into two groups of limiting plates 5, and the limiting plates 5 are used to limit the position of the clamping plate 7, so that the two cores 1 are connected to each other, improving the connection stability of two adjacent cores 1. By clamping the primary winding 2 and the secondary winding 3 into the pressing portion 82 and rotating the bolt 84 to screw the bolt 84 into the second threaded hole on the core 1, the primary winding 2 and the secondary winding 3 are pressed by the pressing portion 82, and thus the winding stability of the primary winding 2 and the secondary winding 3 can be improved.
