[0002] Transformer winding refers to the circuit part of the transformer, usually refers to the coil in the transformer, which is a coil wound by wire. The transformer is generally wound by two or more copper wires or aluminum wires with high conductivity. It is used in power systems. The transformer winding should have sufficient insulation strength, mechanical strength and heat resistance. Transformer windings are usually divided into layer type and pancake type. The transformer winding is the core component of the transformer. During the winding process, the tightness of the winding determines the electrical performance and mechanical strength of the winding, so the winding needs to be compressed during the winding process.

[0025] As an embodiment of the present invention, an oil cylinder 2 71 is provided inside the extrusion cylinder 7, and a push rod 18 is installed inside the extrusion cylinder 7 through a spring.

[0026] When the clamping head 5 moves back and forth in the rotating plate 6, the movable rack 1 62 fixedly installed on both sides of the top of the clamping head 5 engages with the rotating gear 63, and then the rotating gear 63 engages with the movable rack 2 64, so that the tail end of the movable rack 2 64 moves as a piston inside the oil cylinder 1 67, and the internal oil is transmitted to the oil cylinder 2 71 through the hose 65, so that the piston rod 72 in the oil cylinder 2 71 moves outward and squeezes the spring inside the extrusion cylinder 7, thereby increasing the pressure of the spring, and thereby increasing the pressure of the push rod 18 on the rotating plate 6.

[0031] Working principle: When using this device, the motor drives the rotating rod 8 to rotate, causing the rotating plate 6 fixedly connected to the rotating rod 8 and the extrusion cylinder 7 fixedly installed through the connecting rod 81 to rotate synchronously. When the offset is completed, the rotating shaft 68 at the bottom of the rotating plate 6 is rotated to drive the threaded rod 61 to rotate, thereby causing the pressing head 5 connected to the threaded rod 61 to adjust its front and rear position along the slide groove on the rotating plate 6, so that the pressing head 5 can be adjusted to the appropriate position to apply pressure to the transformer winding; When the pressing head 5 moves back and forth, if the specifications of the transformer are different, the pressing head 5 is driven to move toward the bottom end of the rotating plate 6 by rotating the rotating shaft 68.
