Description

Technical Field

[0001] This utility model belongs to the technical field of motor manufacturing, and in particular relates to a centrifugal force winding fork mechanism. Background Technology

[0002] In the production process of electric motors, the winding of enameled wire is required. This operation is often carried out manually or by a winding machine. Manual winding is relatively troublesome, time-consuming and labor-intensive, while using a winding machine can significantly improve the winding efficiency. Currently, the pilot-operated flying fork type winding machine is widely used. This type of winding machine consists of two parts: a rotating chassis and a rotating flying fork. The rotating flying fork is mounted on the rotating chassis and driven by the chassis. After passing through the tensioner, the enameled wire is connected to the rotating flying fork. The rotation of the rotating flying fork winds the enameled wire onto the corresponding position of the motor stator. Therefore, the quality and performance of the rotating flying fork determine the quality of the winding.

[0003] Therefore, a winding fly fork, as disclosed in patent number CN201821167146.5, was developed. This fly fork includes a frame, a first side plate, and a second side plate. The first and second side plates are positioned opposite each other and form a gap. A first wire guide hole and a first roller are provided in the gap. The first wire guide hole and the first roller are spaced along the length of the fly fork frame to form a first wire passage channel. A first wire guide is also provided in the first wire passage channel to guide and protect the enameled wire passing through it. However, this structure has rollers inside the fly fork frame. The rollers are meant to guide and protect the enameled wire passing through, preventing wire skipping, scratches, and damage during winding, thus ensuring winding quality and reducing motor manufacturing costs. However, during use, it was found that although the rollers also have a tensioning effect on the enameled wire passing through, this tension is constant, resulting in poor tension and potentially leading to unsatisfactory winding later on. Utility Model Content

[0004] The purpose of this utility model is to provide a centrifugal winding fork mechanism, which solves the problem that the existing winding fork uses rollers inside to guide and tension the enameled wire, but the tension force of the rollers on the enameled wire is constant, resulting in poor tension effect and easy to lead to unsatisfactory winding in the later stage.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a centrifugal winding fork mechanism, comprising an integrated fork frame. The integrated fork frame has a wire hole extending along its length. One end of the wire hole is fitted with a wire tube. A second wire hole extending along its length is located within the wire tube. The second wire hole communicates with the first wire hole to form a passageway for the enameled wire. A first inclined groove and a second inclined groove are provided within the first wire hole, penetrating the first wire hole. The first and second inclined grooves are parallel and vertically distributed within the first wire hole. A third inclined groove is located between the first and second inclined grooves within the first wire hole. The third inclined groove mirrors the first inclined groove. A tungsten steel rod is movably inserted into the lower end of the first inclined groove. A tungsten steel rod is movably inserted into the lower end of the second inclined groove. A tungsten steel rod is fixedly connected to the lower end of the third inclined groove. The tungsten steel rods one, two, and three form an S-shaped channel for the enameled wire to pass through.

[0007] Preferably, for ease of installation, the integrated fly fork holder includes a fly fork base and a fly fork handle. The wire hole is placed inside the fly fork handle. Each side of the fly fork base has one or more mounting through holes. The center of the fly fork base has a wire through hole communicating with the wire hole. One end of the wire tube is inserted into the fly fork handle.

[0008] Preferably, to facilitate adjustment of tension, a set screw for adjusting the position of the tungsten carbide rod three in the third inclined groove is threaded to the side of the fly fork handle. The head of the set screw is rotatably connected to the side of the tungsten carbide rod three, and the other end of the set screw is provided with an internal hexagonal groove.

[0009] Preferably, to facilitate the replacement or removal of the corresponding tungsten steel rod later, one end of the first inclined waist groove, the second inclined waist groove, and the third inclined waist groove protrudes from the side of the fork handle, and the side of the fork handle is detachably connected to a pressure plate that closes one end of the first inclined waist groove, the second inclined waist groove, and the third inclined waist groove.

[0010] Preferably, for easy removal, the pressure plate is provided with two mounting through holes, and a locking screw passes through each mounting through hole and is then threaded to the side of the fork handle.

[0011] Preferably, in order to further tension the enameled wire, a guide rod 1 and two parallel guide rods 2 are also provided from top to bottom inside the wire hole 1, and the two guide rods 2 form a wire channel.

[0012] As a preferred option, for ease of later installation, a locking screw is inserted into the side of the fork handle and connected to the threaded conduit inside the fork handle.

[0013] Preferably, the end of the conduit placed inside the fork handle is provided with a wire nozzle.

[0014] The present invention has the following beneficial effects: As the fork disc rotates, the two movable tungsten steel rods swing back and forth along the corresponding inclined grooves under centrifugal force, thus forming an S-shaped tension force. Therefore, the internal tension force can be automatically changed with the rotation of the fork, thereby improving the tensioning effect. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Example 1

[0024] Please see Figure 1-5As shown, this embodiment discloses a centrifugal winding fork mechanism, including an integrated fork holder 1. The integrated fork holder 1 has a wire hole 2 extending along its length. A wire tube 3 is provided at one end of the wire hole 2. A second wire hole 4 extending along its length is provided inside the wire tube 3. The second wire hole 4 communicates with the first wire hole 2 to form a wire passage for the enameled wire. A first inclined groove 5 and a second inclined groove 6 penetrating the first wire hole 2 are provided inside the first wire hole 2. The first inclined groove 5 and the second inclined groove 6 are parallel to each other. The wires are arranged vertically and horizontally within the wire hole 2. A third inclined groove 7 is located between the first inclined groove 5 and the second inclined groove 6 within the wire hole 2. The third inclined groove 7 is mirror-finished with the first inclined groove 5. A tungsten steel rod 8 is movably inserted into the lower end of the first inclined groove 5. A tungsten steel rod 9 is movably inserted into the lower end of the second inclined groove 6. A tungsten steel rod 10 is fixedly connected to the lower end of the third inclined groove 7. The tungsten steel rods 8, 9, and 10 form an S-shaped channel for passing through the enameled wire.

[0025] Preferably, for ease of installation, the integrated fly fork holder 1 includes a fly fork base 101 and a fly fork handle 102. The wire hole 2 is placed inside the fly fork handle 102. The fly fork base 101 has one or more mounting through holes 103 on both sides. The center of the fly fork base 101 has a wire through hole 104 communicating with the wire hole 2. One end of the wire tube 3 is inserted into the fly fork handle 102. Preferably, the end of the wire tube 3 placed inside the fly fork handle 102 is provided with a wire nozzle 19. With the above structure, the installation operation of this device can be achieved by simply passing a screw through the mounting through hole 103 and threading the screw to the fly fork disc.

[0026] Preferably, to facilitate tension adjustment, a set screw 11 for adjusting the position of the tungsten carbide rod 10 in the third inclined groove 7 is threaded onto the side of the fork handle 102. The head of the set screw 11 is rotatably connected to the side of the tungsten carbide rod 10, and the other end of the set screw 11 is provided with an internal hexagonal groove 12. Later, by inserting a professional tool into the internal hexagonal groove 12, the set screw 11 can be rotated to adjust the position of the tungsten carbide rod 10 in the third inclined groove 7, thereby manually adjusting the tension.

[0027] Preferably, to facilitate the replacement or removal of the corresponding tungsten steel rods later, one end of the first inclined groove 5, the second inclined groove 6, and the third inclined groove 7 is exposed on the side of the fork handle 102. The side of the fork handle 102 is detachably connected to a pressure plate 13 that closes one end of the first inclined groove 5, the second inclined groove 6, and the third inclined groove 7. To facilitate removal, the pressure plate 13 is provided with two mounting through holes 18. A locking screw 17 passes through each mounting through hole 18 and is threaded to the side of the fork handle 102. In this embodiment, to facilitate the replacement of the corresponding tungsten steel rods later, a pressure plate 13 is pressed against the side of the fork handle 102 by two locking screws 17. After loosening the locking screws 17, the pressure plate 13 can be removed, exposing the various inclined grooves inside.

[0028] Preferably, in order to further tighten the enameled wire, a guide rod 14 and two parallel guide rods 15 are also provided from top to bottom inside the wire hole 2. The two guide rods 15 form a wire channel. In this embodiment, the guide rods 14 and 15 are provided inside the wire hole 2 to guide the passing enameled wire.

[0029] Preferably, to facilitate later installation, a locking screw 16 is inserted into the side of the fork handle 102 and threadedly connected to the conduit 3 inside the fork handle 102. In this embodiment, the conduit 3 can be removed from the fork handle 102 by unscrewing the locking screw 16 later, which facilitates later installation and disassembly.

[0030] The working principle of this structure is as follows: First, the device is installed on the fork plate, so that the winding fork can rotate with the fork plate, and the entire enameled wire routing is as follows. Figure 4 As indicated by the arrow, in this structure, three inclined grooves are set inside the fly fork handle 102, allowing the tungsten steel rod 8, tungsten steel rod 9, and tungsten steel rod 10 inside to form an S-shaped wire passage for passing the enameled wire. The tungsten steel rods placed in two of the inclined grooves are movable, while the tungsten steel rod in the middle inclined groove is fixed. During operation, as the fly fork disc rotates, the two movable tungsten steel rods move along the corresponding inclined grooves (i.e., swing back and forth) under centrifugal force, ultimately forming an S-shaped tension. Therefore, this structure can automatically change the internal tension as the fly fork rotates, ultimately improving the tensioning effect.

[0031] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
