Description

Technical Field

[0001] This utility model relates to the technical field of transformer production equipment, specifically a transformer frame mounting shaft for a transformer winding machine. Background Technology

[0002] In transformer manufacturing, the winding machine is the core equipment used to precisely wind copper or aluminum wire onto the transformer bobbin. The transformer bobbin mounting shaft, as a critical component of the winding machine, functions to fix the bobbin and ensure stability and coaxiality during the winding process, directly affecting winding accuracy and the transformer's electrical performance. However, traditional mounting shafts have significant drawbacks in practical applications and urgently require technological improvement.

[0003] Currently, most widely used transformer bobbin mounting shafts are fixed-size rectangular shafts, which have poor compatibility with the bobbin's internal cavity. The main problems include:

[0004] 1. Because the rectangular shaft and the inner cavity of the bobbin cannot fit completely, there is a gap between them (usually 0.1-0.5mm). During winding, the bobbin is prone to slippage or radial wobble, leading to winding deviation, loosening, or even breakage. To solve this problem, operators need to wrap multiple layers of tape (such as polyester tape) around the surface of the rectangular shaft to fill the gap. However, the tape wears out rapidly during high-speed winding due to friction and mechanical stress, resulting in a short service life (usually only lasting a few hours). Frequent machine shutdowns are required for replacement, severely reducing production efficiency.

[0005] 2. The internal cavity dimensions of transformer frames vary greatly depending on the model. Traditional rectangular shafts need to be designed separately for each specification, which increases production costs.

[0006] Therefore, this application provides a transformer bobbin mounting shaft for a transformer winding machine to solve the above problems. Utility Model Content

[0026] Furthermore, the adjusting plate 5 has an inclined surface on the side away from the limiting seat 1, which facilitates the insertion of the transformer frame onto the mounting shaft 3.

[0027] Furthermore, a rubber pad 51 is provided on the side of the adjusting plate 5 away from the mounting shaft 3, which can increase the friction between the adjusting plate 5 and the transformer frame and prevent the transformer frame from sliding or sliding along the axial direction during the winding process.

[0030] The transformer frame is fitted onto the mounting shaft 3, and one end of the transformer frame is in contact with the inclined surface of the isosceles trapezoidal part of the connecting platform 2.

[0031] By rotating the worm 6 with handle 61, the worm 6 drives the worm wheel 41 to rotate, and the worm wheel 41 drives the screw 4 to rotate. As the screw 4 rotates, the adjusting plate 5 moves along the slide groove, thereby making the adjusting plate 5 contact the inner wall of the transformer frame, thus positioning the transformer frame and preventing the transformer frame from shaking during the winding process.
