[0002] The transformer winding device is usually a tool used in the manufacturing and maintenance process of the transformer. It is used to accurately wind the wire or cable onto the transformer core. The electromagnetic performance and service life of the transformer largely depend on the winding quality of the cable or wire. Therefore, the winding device is a very important link.

[0003] However, for the existing transformer winding machine, the transformer is fixed by arranging slidable clamping plates on both sides of the transformer, and the sliding plates are driven to slide by rotating the nuts to clamp the transformer. The operator needs to manually rotate the nuts to adjust the position of the sliding plates. The operation process is relatively laborious, especially when the position of the clamping plates needs to be adjusted frequently, which increases labor intensity and fatigue. In addition, the clamping plates are directly connected to the transformer. If the clamping force of the clamping plates is too large, the transformer will be deformed, and if the force is too small, the transformer cannot be fixed, so it is not very practical.
