Description

Technical Field

[0001] The utility model relates to the technical field of the combination of inductance coils, in particular to a combination mold for inductance coils. Background Technique

[0002] An inductance coil is an electronic component that works based on the principle of electromagnetic induction and is widely used in various circuits. Its basic working principle is that when an electric current passes through a wire, a magnetic field is generated around the wire, and this magnetic field will in turn affect other wires within the range of this electromagnetic field. The inductance coil can store energy and generate a magnetic field for energy transfer and transformation, and has self-inductance, which can stabilize the change of the electric current. The design and manufacture of inductance coils need to consider multiple factors, including the number of turns of the coil, the winding method, the presence or absence of a magnetic core and the magnetic core material, etc. Generally, the more turns the coil has and the denser the winding, the greater the inductance.

[0003] In the prior art, most of the combination molds for inductance coils adopt a fixed-frame design. Such molds with a fixed frame have obvious limitations when winding inductance coils. The number of winding turns and the coil diameter are both preset and fixed, and cannot be flexibly adjusted according to actual needs. If it is necessary to change the number of turns or the diameter of the coil, the operator has to disassemble the existing mold and replace it with a suitable new mold. This process is not only complicated and cumbersome, but also may lead to long-term shutdowns, seriously affecting production efficiency. Moreover, the mold replacement process usually involves multiple steps, including the disassembly, cleaning, reinstallation and debugging of the mold. This series of operations not only increases the difficulty and labor intensity of the operation, but also is prone to problems such as improper installation or inaccurate debugging, thus affecting the quality of the final product. The time required to replace the mold also significantly extends the entire production cycle, further reducing production efficiency and increasing production costs at the same time. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a combination mold for inductance coils to solve the technical problem that the mold cannot adjust the number of winding turns and the diameter.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A combination mold for inductance coils, including a base, one side of the base is fixedly connected with a motor, the output end of the motor is fixedly connected with a fixed disk, and fixed disks are arranged on both sides of the base. A lead screw is movably connected between the two groups of fixed disks. A fixed block is sleeved on the surface of the lead screw. A connecting block is fixedly connected to the surface of the fixed block, and the connecting blocks are symmetrically distributed at equal intervals on the four sides of the fixed block. The top end of the connecting block is fixedly connected with a movable ring. First rotating shafts are symmetrically and movably connected to the surface of the movable ring at equal intervals. One end of the first rotating shaft is fixedly connected with a connecting plate, one end of the connecting plate is fixedly connected with a second rotating shaft, and a winding plate is movably connected to one side of the second rotating shaft.

[0006] By adopting the above technical solution, a lead screw is arranged between two sets of fixed disks. The lead screw is rotated by a handle, thereby driving a fixed block sleeved on the surface of the lead screw to move reciprocally. The fixed block is connected to a movable ring through a connecting block. Under the action of a limiting ring and through the action of a rotating shaft, an outward thrust or an inward pulling force is generated on four sets of winding plates simultaneously. Sliders at both ends of the winding plates expand or contract synchronously along the guiding tracks, so that the distance between the winding plates can be accurately adjusted. Thus, the number of turns and the diameter of the inductance coil can be flexibly adjusted without replacing the mold. This design simplifies the operation process, reduces the labor intensity, and improves the production efficiency and flexibility.

[0007] Further, the winding plates are evenly and symmetrically distributed at the top of the second rotating shaft, and the four sets of winding plates are arc-shaped.

[0008] By adopting the above technical solution, the winding plates play the role of winding the coil.

[0009] Further, a slider is fixedly connected to the bottom end of one side of the winding plate, and a guiding track matched with the slider is provided on the fixed disk.

[0010] By adopting the above technical solution, the guiding track plays the role of guiding the slider.

[0011] Further, a housing is movably connected between the two sets of fixed disks, and a wire slot is provided on the surface of the housing.

[0012] By adopting the above technical solution, the housing plays the role of protecting the internal structure, and the wire slot plays the role of fixing the wire ends.

[0013] Further, a limiting ring is fixedly connected to the outer side of the movable ring, and a groove matched with the connecting plate is provided on the surface of the limiting ring.

[0014] By adopting the above technical solution, the limiting ring plays the role of limiting the movable ring and the connecting plate.

[0015] Further, a handle is fixedly connected to one side of the lead screw, and one end of the lead screw penetrates through the fixed disk.

[0016] By adopting the above technical solution, the handle plays the role of rotating the lead screw.

[0017] In summary, the present utility model mainly has the following beneficial effects: By arranging a lead screw between two groups of fixed disks, the present utility model rotates the lead screw by using a handle, thereby driving a fixed block sleeved on the surface of the lead screw to move reciprocally. The fixed block is connected to a movable ring through a connecting block. Under the action of a limiting ring and through the action of a rotating shaft, the movable ring generates an outward thrust or an inward pulling force on four groups of winding plates simultaneously. The sliders at both ends of the winding plates expand or contract synchronously along the guiding tracks, so that the distance between the winding plates can be accurately adjusted. Thus, the number of turns and the diameter of the inductance coil can be flexibly adjusted without replacing the mold. This design simplifies the operation process, reduces the labor intensity, and improves the production efficiency and flexibility. BRIEF DESCRIPTION OF THE DRAWINGS

A winding plate 7 is movably connected to one side of the second rotating shaft 12. When in use, the wire to be wound is passed through the wire slot 4 on the surface of the housing 3. After starting the motor 2, the motor 2 drives the fixed disk 5 to rotate, and the fixed disk 5 drives the four winding plates 7 to rotate synchronously, so as to realize the winding of the coil;

[0028] If it is necessary to adjust the number of turns and diameter of the winding, the handle 17 can be rotated. When the handle 17 is rotated, it drives the lead screw 8 to rotate, so as to drive the fixed block 9 sleeved on the surface of the lead screw 8 to move reciprocally along the lead screw. The fixed block 9 is connected to the movable ring 14 through the connecting block 10. Under the action of the limiting ring 15, the movable ring 14 exerts a simultaneous outward thrust or inward pulling force on the four winding plates 7 through the action of the rotating shaft. During this process, the sliders 14 at both ends of the winding plate 7 will expand or contract synchronously along the guide rail 6, so as to accurately adjust the distance between the winding plates 7 and realize the adjustment of the number of winding turns and diameter.

[0029] Please refer to Figure 1 、 Figure 4 、 Figure 5 and Figure 6 .
