Description

Technical Field

[0001] This utility model relates to the field of inductor processing technology, specifically to a winding fixture for inductors. Background Technology

[0002] Inductor winding fixtures (or winding machines, winding tools) are equipment specifically designed for the efficient and precise winding of inductor coils. Inductor manufacturing requires precise winding processes to ensure that the inductance, stability, and performance meet design requirements. Fully automatic winding machines are used for mass production and can efficiently wind inductors of various specifications. Fully automatic winding machines feature accurate counting, constant winding speed, and adjustable coil spacing, which improves production efficiency, reduces human error, and ensures the consistency and high quality of inductors.

[0003] For example, a winding fixture for inductors, disclosed in CN222600739U, includes: a main assembly, which includes a support frame; and a clamping assembly, which includes a fixed post, a movable frame, a movable plate, a connecting rod, a silicone plate, and a connecting groove. The fixed post is fixed to the middle of the upper surface of the support frame, the connecting groove is opened inside the top of the fixed post, the movable frame is fixed to the upper surfaces on both sides of the fixed post, and two sets of movable frames are provided. The movable plate is movably connected inside the movable frame, and the connecting rod is fixed to the middle of the lower surface of the movable plate. This design addresses the problem that in existing winding fixtures, during actual use, the inductor's valve core is placed inside the rotating post, and the valve core can be rotated. With the cooperation of a winding machine, the inductor can be processed. However, when the winding machine stops, the enameled wire retracts into the unwinding reel, requiring time to find the wire end during subsequent production, thus reducing the efficiency of inductor production.

[0004] The aforementioned patent proposes that by setting a clamping component, the end of the enameled wire is placed inside the connecting groove. When the movable plate is moved and the concealed snap-fit ​​block is inserted into the concealed snap-fit ​​groove, the end of the enameled wire can be quickly found. After fixing the enameled wire, a pushing force is applied to the handle, and the blade cuts the enameled wire. However, in actual use, the diameter of the enameled wire is different for different inductors, resulting in poor fixing effect of the above device on the enameled wire, which affects the production efficiency of inductors. Utility Model Content

[0005] The purpose of this invention is to provide a winding fixture for inductors to solve the problem of poor fixing effect of enameled wire mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a winding fixture for an inductor, comprising a winding structure and a base installed at the bottom of the winding structure, wherein a rotating shaft is movably installed at the top of the base and on one side of the winding structure, the winding structure comprising a fixed shaft, wherein an upper moving member and a lower fixing member are respectively installed at the upper and lower ends of the fixed shaft, an adjusting member is installed between the outer sides of the lower fixing member and the upper moving member, and a cutting member is installed on the outer surface of the fixed shaft;

[0007] The upward moving component includes a fixed ring B and a tapered tube B installed at the bottom end of the fixed ring B. A positioning groove is provided on the outer surface of the fixed shaft, and a positioning block B is installed on the inner wall of the fixed ring B.

[0008] Preferably, the lower fixing component includes a fixing ring A and a tapered tube A installed at the top of the fixing ring A. A positioning block A is installed on the inner wall of the tapered tube A, and rubber rings are installed on the outer surfaces of the lower end of the tapered tube B and the upper end of the tapered tube A.

[0009] Preferably, the adjusting component includes an outer strip A and an outer strip B disposed at the lower end of the outer strip A. A limiting plate is installed at the top of the outer strip B. A threaded hole is provided through the middle of the limiting plate and the outer strip B. A rotating rod is movably installed at the middle of the outer strip A. A threaded groove is provided on the outer surface of the lower end of the rotating rod.

[0010] Preferably, a hand handle is installed above the outer strip A and at the top of the rotating rod, and a limiting seat is installed at the bottom of the rotating rod and at the lower end of the outer strip B.

[0011] Preferably, the cutting component includes a rectangular strip, with an inverted T-shaped post installed at both the bottom and top of the rectangular strip, an outer sliding cylinder slidably installed on the outer surface of the rectangular strip, and a cutter fixedly installed on the outer surface of the outer sliding cylinder.

[0012] Preferably, an upper extension plate and a lower extension plate are respectively installed at the upper and lower ends of the fixed shaft, and an inverted T-shaped groove is formed at the bottom end of the upper extension plate and the top end of the lower extension plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The present invention discloses a winding fixture for an inductor, wherein one end of an enameled wire is inserted between a lower fixing component and an upper moving component. The position of the upper moving component is adjusted according to the diameter of the enameled wire. A rubber ring installed on the outer surface of tapered tube B and tapered tube A makes direct contact with the enameled wire.

The position of the upper moving component can be adjusted, which makes it easy for this device to fix enameled wires of different diameters and avoids the difficulty in finding the end of the enameled wire when winding the next set of wires.

[0015] 2. The present invention discloses a winding fixture for an inductor, which pushes the cutting component to move to one side of a fixed axis. The inverted T-shaped posts installed at both ends of the rectangular strip slide within the lower and upper extension plates respectively. The inverted T-shaped grooves on the outer surfaces of the lower and upper extension plates restrict the movement of the inverted T-shaped posts, thereby preventing the cutter from shifting position when cutting the enameled wire.

[0022] Example 1: Please refer to Figure 1 , Figure 2 and Figure 4A winding fixture for an inductor includes a winding structure 1 and a base 2 installed at the bottom of the winding structure 1. A rotating shaft 3 is movably installed at the top of the base 2 and on one side of the winding structure 1. The winding structure 1 includes a fixed shaft 11. An upward moving member 14 and a lower fixing member 13 are respectively installed at the upper and lower ends of the fixed shaft 11. An adjusting member 12 is installed between the outer sides of the lower fixing member 13 and the upward moving member 14. A cutting member 15 is installed on the outer surface of the fixed shaft 11.

[0023] The upward moving component 14 includes a fixed ring B141 and a tapered tube B142 installed at the bottom of the fixed ring B141. A positioning groove 111 is provided on the outer surface of the fixed shaft 11. A positioning block B143 is installed on the inner wall of the fixed ring B141. The positioning block B143 is slidably installed inside the positioning groove 111.

[0024] The lower fixing component 13 includes a fixing ring A131 and a tapered tube A132 installed at the top of the fixing ring A131. A positioning block A133 is installed on the inner wall of the tapered tube A132. Rubber rings 16 are installed on the outer surfaces of the lower end of the tapered tube B142 and the upper end of the tapered tube A132. The positioning block A133 is slidably installed inside the positioning groove 111. The rubber rings 16 increase the friction between the device and the enameled wire.

[0025] The adjusting component 12 includes an outer strip A121 and an outer strip B122 disposed at the lower end of the outer strip A121. A limiting plate 123 is installed at the top of the outer strip B122. A threaded hole 128 is provided through the limiting plate 123 and the middle end of the outer strip B122. A rotating rod 125 is movably installed at the middle end of the outer strip A121. A threaded groove 126 is provided on the outer surface of the lower end of the rotating rod 125. The outer strip A121 is installed on the outer surface of the fixing ring B141, and the outer strip B122 is installed on the outer surface of the fixing ring A131.

[0026] A hand lever 127 is installed above the outer bar A121 and at the top of the rotating rod 125. A limit seat 124 is installed at the bottom of the rotating rod 125 and at the lower end of the outer bar B122. The hand lever 127 is convenient for the operator to hold, and the limit seat 124 restricts the movement range of the upward moving member 14.

[0027] In this embodiment: One end of the enameled wire is inserted between the lower fixing member 13 and the upper moving member 14. The position of the upper moving member 14 is adjusted according to the diameter of the enameled wire. The handheld lever 127 is held and rotated, causing the rotating rod 125 with the threaded groove 126 to rotate inside the threaded hole 128.
