Description

Technical Field

[0001] The utility model relates to the technical field of transformer winding, in particular to a transformer winding jig. Background Art

[0002] The winding package of the high-voltage transformer is usually wound by a winding jig and a winding machine, and is generally wound into two types: rectangular wire packages and round wire packages. Traditional network transformer winding jigs can only wind rectangular wire packages or round wire packages, and cannot have the function of winding both types of wire packages. In addition, when winding wire packages of different sizes, the jig of the corresponding size needs to be replaced.

[0003] Patent CN212542182U proposes a network transformer winding jig component, which connects the mounting block with the winding machine. When winding a rectangular wire package, the L-shaped rod of the locking mechanism is clamped with the end of the cylinder to lock the circular wire package mechanism inside the cylinder. The rectangular wire package is wound by the exposed rectangular wire package mechanism, and rectangular wire packages of different sizes can be wound by selecting winding rods of different steps; when winding a circular wire package, first overcome the elastic force of the compression spring to lift the ring and the L-shaped rod, then slide the circular wire package mechanism out of the cylinder through the hoop, and then rotate the L-shaped rod to release the L-shaped rod. The compression spring force causes the L-shaped rod to be clamped at the end of the cylinder away from the end plate, locking the circular wire package mechanism. At this time, the circular wire package mechanism completely covers the rectangular wire package mechanism, and circular wire packages of different diameters can be wound by four winding petals of the same diameter at different steps of the circular wire package mechanism.

[0004] In the above scheme, the staggered L-shaped rods and cylinders can be used to switch between winding circular wire packages or rectangular wire packages. However, although this technical method has multiple sizes to choose from for the winding of each wire package, it is impossible to accurately adjust the size of the fixture. For some specific products, it is impossible to meet the winding requirements of precise wire package sizes. Utility Model Content
