[0017] As shown in the figure, 1. Elastic clamping device, 2. Magnetic core, 3. Screw. Detailed Implementation

[0018] like Figure 1 and Figure 2 As shown, this embodiment provides a simple I-shaped, holeless magnetic core winding clamp. The winding clamp is easy to assemble and disassemble quickly in small-batch production. It includes an elastic clamping device 1. The main body of the elastic clamping device 1 is cylindrical, and half of the cylindrical feature of the elastic clamping device 1 is a hollow structure with a cut through groove in the middle. The other half is a connecting part, in which the interior of the connecting part is a blind hole threaded groove for threaded connection with the winding machine shaft. One end of the hollow structure of the elastic clamping device 1 has an inwardly concave stepped surface, and the stepped surface contains an I-shaped magnetic core 2. At the same time, a screw 3 is provided on the vertical side end face of the hollow structure for fastening the clamp.

[0019] The elastic clamping device 1 is made of brass round bar; and the diameter of the stepped surface of the elastic clamping device 1 after processing is larger than the outermost circumference diameter of the magnetic core 2, and the value range is 0.5 to 1 mm.

[0020] The depth of the inner hole of the stepped surface at one end of the elastic clamping device 1 is less than the circumferential height of one end of the clamped magnetic core skeleton 2.

[0021] Screw 3 is located in a set of coaxial circular holes. The circular holes are located on the vertical sides of the through slot cut in the elastic clamping device 1. The set of circular holes includes one through hole feature and one threaded hole feature. Screw 3 is a standard screw of national standard and is matched with the threaded hole feature. It can be tightened by tools or by hand according to the worker's operating habits. Furthermore, in the automated production line, screw 3 can also be replaced by a pneumatic or hydraulic detachable clamping mechanism.

[0022] The hollow structure of the elastic clamping device 1 is machined using a boring tool. The thickness of the hollow structure is no more than 1.5mm, and the length of this section of the hollow structure is more than 3 times the inner diameter of the elastic clamping device 1 to ensure sufficient elastic deformation distance.

[0023] The through slots cut into the hollow structure are processed by wire EDM, and the opening distance is 1mm. This dimension must match the dimension of the step surface, otherwise the workpiece cannot be clamped.

[0024] like Figure 3As shown, the connecting part at the other end of the elastic clamping device 1 is a groove structure. By connecting to different specifications of adapter threaded ports, it is compatible with different models of winding machines. It can be redesigned or adapter parts can be added according to the shaft structure of different winding machines.

[0025] The standard winding clamp used to clamp the I-shaped magnetic core 2 in this embodiment is as follows: Figure 1 This illustrates the usage of standard winding clamps and universal winding machines, as follows: Figure 3 This is an illustration; the operating steps are as follows:

[0026] The winding clamp is mounted on the winding shaft of the general winding machine and fixed in place; ensuring that the rotation axes are aligned and that the clamp does not jump violently when the winding shaft rotates.

[0027] Insert the I-shaped magnetic core 2 into the stepped groove of the winding clamp. Secure the winding clamp with screw 3; after securing, the workpiece should not rotate or fall out. Perform the winding operation on the workpiece using wire.

[0028] Remove the wound workpiece from the winding fixture and repeat the process for the next product.

[0029] Specifically, the entire winding fixture is mounted on the winding shaft of the winding machine, and then the magnetic core 2 is installed. The beginning of the enameled wire is soldered to one end pin of the I-shaped magnetic core 2. The winding machine is turned on, and the winding shaft is rotated to allow the enameled wire to be wound in parallel stacks inside the I-shaped magnetic core 2. After winding to the specified number of turns, the enameled wire is cut, and the end is soldered to the other end pin of the magnetic core 2. The screw 3 is loosened, and the wound magnetic core (now called an inductor coil) is removed. A new empty I-shaped magnetic core 2 is then installed to continue the process.

[0030] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
