Abstract

This utility model discloses a winding structure for transformer production, belonging to the technical field of transformer production equipment. It includes a frame, with fastening plates slidably mounted on turntables on both sides of the shaft. A limiting plate is slidably inserted into the shaft. Uniformly distributed limiting grooves are formed on the outer walls of the left and right sides of the shaft. The inner side of the limiting plate is inserted into the corresponding limiting groove. A positioning slide is rotatably mounted at the end of the shaft, and the positioning slide can slide along the shaft. A positioning post is fixedly connected to the inner side of one end of the positioning slide. When the coil drum is fixed, the positioning post is inserted tightly to the top front of the limiting plate. This utility model achieves double limiting of the limiting plate, thereby enhancing the limiting and fixing effect of the limiting plate on the coil drum. It saves time and effort in operation, effectively improves the loading and unloading efficiency of the coil drum, ensures the stability of the winding process, and thus effectively improves the technical effect of improving the working efficiency of transformer winding.
