[0007] Further, in order to support the partition disc, prevent the limiting ring and rotating lug from deforming due to excessive stress, a plurality of ring grooves are formed on the outer periphery of the middle pole, and the partition disc is clamped in the ring groove when it is sleeved on the middle pole.
[0008] Further, a grommet is installed on the lower end of the lower disc by a screw.
[0009] Further, in order to facilitate the transfer of multiple semi-finished products and limit the partition disc to prevent it from rotating during transfer, a concave rod is inserted into the lower disc, and the vertical section of the concave rod is arranged on the partition disc.
[0010] Furthermore, in order to limit the semi-finished product located on the top layer, a pressure plate is provided at the upper end of the vertical section of the concave rod, and the pressure plate acts on the upper end of the annular iron core located on the top layer.
[0011] Furthermore, in order to lock the lower end of the concave rod to facilitate the transfer of multiple semi-finished products, a capped pin is threadedly connected to the lower end of the concave rod. The diameter of the cap on the upper end of the capped pin is equal to the diameter of the concave rod. A pair of rotating shafts are rotatably provided on the lower plate. A rotating plate is provided at the upper end of the rotating shafts. The rotating plate is located above the lower plate. A limiting plate is provided at the lower end of the rotating shafts. A slot is machined on one side of the inner end of the limiting plate. The rod part of the capped pin passes through the slot.
[0012] The advantages of the above technical solution are:
[0013] This invention enables the stacking of semi-finished toroidal transformers, thereby improving the utilization rate of the processing platform area. In addition, it facilitates the lifting and transfer of multiple finished toroidal transformers. Attached Figure Description
[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0016] Figure 2 A three-dimensional structure of one embodiment is shown. Figure Two .
[0017] Figure 3 A three-dimensional structure of one embodiment is shown. Figure Three . Detailed Implementation
[0018] like Figures 1-3 As shown, a ring-shaped iron core placement fixture includes a lower plate 1, and a washer 10 is installed at the lower end of the lower plate 1 by screws.
[0019] A central rod 3 is coaxially fixed to the lower plate 1 by screws. A side rod 2 is installed on the lower plate 1 by screws. The side rod 2 is located on one side of the central rod 3. A rotating convex plate 20 is rotatably provided on the side rod 2. A partition plate 22 is integrally formed at the other end of the rotating convex plate 20. Limiting rings 21 are provided on the upper and lower sides of the rotating convex plate 20, and the limiting rings 21 are fixed to the side rod 2 by pins. An arc-shaped groove 23 is opened on the partition plate 22. The central rod 3 passes through the arc-shaped groove 23, and the arc-shaped groove 23 is located on the axis of the side rod 2 with the center of the side rod 2. Multiple annular grooves 30 are opened on the outer periphery of the central rod 3. When the partition plate 22 is sleeved on the central rod 3, the partition plate 22 is locked in the annular grooves 30.
[0020] A concave rod 4 is inserted into the lower plate 1. The vertical section of the concave rod 4 passes through the partition plate 22. A pressure plate 40 is provided at the upper end of the vertical section of the concave rod 4, and the pressure plate 40 acts on the upper end of the annular iron core located at the top layer. The lower end of the concave rod 4 is connected to a capped pin 49 by a thread. The diameter of the cap at the upper end of the capped pin 49 is equal to the diameter of the concave rod 4. A pair of rotating shafts 41 are rotatably provided on the lower plate 1. A rotating plate 42 is provided at the upper end of the rotating shafts 41. The rotating plate 42 is located above the lower plate 1. A limiting plate 43 is provided at the lower end of the rotating shafts 41. A slot 44 is machined with an opening on one side of the inner end of the limiting plate 43. The rod part of the capped pin 49 passes through the slot 44.
[0021] In a specific application scenario, such as when placing a toroidal transformer, the bottom partition plate 22 is rotated first, and the middle rod 3 is inserted into the arc-shaped groove 23. Then, the semi-finished toroidal transformer is inserted onto the middle rod 3 from top to bottom and placed on the bottom partition plate 22. Then, multiple semi-finished toroidal transformers are placed on the fixture from bottom to top. After this placement, multiple semi-finished toroidal transformers are stacked vertically, and there is no contact between adjacent semi-finished toroidal transformers, thus avoiding damage to the semi-finished toroidal transformers.
[0022] When transferring the semi-finished transformer, the operator inserts the lower end of the concave rod 4 onto the lower plate 1. During insertion, the concave rod 4 passes sequentially through the partition plate 22, preventing the partition plate 22 from rotating during the transfer and thus avoiding potential damage to the toroidal transformer. Furthermore, after the concave rod 4 is inserted, the rotating plate 42 needs to be rotated so that the rod portion with the capped locking pin 49 passes into the locking groove 44. This limits the lower end of the concave rod 4, and simultaneously limits the upper end of the semi-finished toroidal transformer on the top layer with the pressure plate 40, ensuring safety during transfer. Additionally, during the transfer process, the operator can hold the upper end of the concave rod 4 to perform the transfer operation.
[0023] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
