Description

Technical Field

[0001] This utility model relates to a winding positioning device, and more particularly to a high-voltage coil winding positioning device. Background Technology

[0002] The existing method for winding high-voltage coils involves manually marking lines with a ruler, then winding copper wire along those lines. As the coil mold rotates, the coil is wound onto the mold. However, this winding positioning method has significant technical drawbacks: firstly, marking lines with a ruler is prone to error; secondly, the lack of a limit on the copper wire winding along the line makes it prone to deviation, causing considerable inconvenience to production. This makes the traditional high-voltage coil winding method require more effort to achieve product quality, and it cannot fully guarantee quality. Therefore, there is an urgent need to provide a positioning device for high-voltage coil winding. Utility Model Content

[0003] To address the shortcomings of the aforementioned technologies, this utility model provides a high-voltage coil winding positioning device.

[0004] To solve the above technical problems, the technical solution adopted by this utility model is: a high-voltage coil winding positioning device, which includes a bracket, and a middle plate is horizontally arranged inside the frame of the bracket;

[0005] Several telescopic guide rods of the same specification are supported on the bracket. One end of the telescopic guide rod passes upward through the linear bearing and is locked to the bearing roller at the end. The other end of the telescopic guide rod passes downward through the middle plate and is limited and locked by the cylindrical pin.

[0006] A spring is fitted onto the telescopic guide rod, and the spring is limited between the retaining ring and the intermediate plate.

[0007] Preferably, the bracket includes a vertically distributed base portion and an inclined forward portion connected above the base portion, with an intermediate plate located between the base portion and the inclined forward portion.

[0008] Preferably, the top of the forward-leaning section is provided with a top plate, and the middle plate is parallel to the top plate.

[0009] Preferably, the linear bearing is mounted on the top plate via a flange seat.

[0010] Preferably, the telescopic guide rod is provided with a retaining ring near the linear bearing.

[0011] Preferably, the telescopic guide rod has pin holes for inserting cylindrical pins on its body as it passes downward through the intermediate plate, so that the cylindrical pins are distributed below the intermediate plate.

[0012] Preferably, the telescopic guide rod passing downward through the intermediate plate is cuboid in shape, and the intermediate plate has a square through hole for the cuboid rod to pass through.

[0013] Preferably, a shaft is fixed to the top end of the telescopic guide rod, and a bearing roller is mounted on the shaft.

[0014] Preferably, the surface of the bearing roller has a concave groove.

[0015] This utility model discloses a high-voltage coil winding positioning device. It employs bearing rollers to limit the coil's position, and a telescopic guide rod extends and retracts back and forth according to the coil's shape via spring pressure, maintaining the limiting position without affecting coil rotation. Since the coil mold remains unchanged, the high-voltage coil winding device only needs to be fixed relative to the mold position to perform the winding process. Compared to existing manual marking methods, this device eliminates the possibility of errors during manual marking, reducing product defect rates. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] This utility model discloses a high-voltage coil winding positioning device, mainly used for guiding and positioning the high-voltage coil winding operation on the coil mold 15. The overall structure is set as follows: Figure 1 As shown, the main structural components include: bracket 1, telescopic guide rod 2, spring 4, linear bearing 5, and bearing roller 7.

[0025] Among them, bracket 1 serves as the structural support for this coil winding positioning device, and its arrangement is as follows: Figure 2 As shown, for ease of description, the bracket 1 is divided into a base part 11 and a forward tilting part 12, and a middle plate 14 is horizontally provided inside the frame of the bracket 1.

[0026] The base portion 11 is vertically distributed to support the bracket 1, and mounting holes are provided on the bottom plate of the base portion 11 to facilitate the installation and fixing of this high-voltage coil winding positioning device.

[0027] The forward tilting part 12 is inclinedly connected above the base part 11 so that the subsequent bearing roller 7 can better fit the winding mold 15.

[0028] The intermediate plate 13 is located between the base portion 11 and the forward tilting portion 12, and is parallel to the top plate 13 provided at the top of the forward tilting portion 12, so that the telescopic guide rod 2 is installed based on the support of the top plate 13 and the intermediate plate 14.

[0029] like Figure 1 As shown, several retractable guide rods 2 of the same specification are supported on the bracket 1. The retractable guide rods 2 are spaced apart and arranged in a straight line. One end of the retractable guide rod 2 passes upward through a linear bearing 5 and is locked to a bearing roller 7 at the end. The bearing roller 7 is used to guide and position the high-voltage coil.

[0030] The other end of the telescopic guide rod 2 passes downward through the intermediate plate 4 and is locked by the cylindrical pin 3. Specifically, the telescopic guide rod 2 passes downward through the intermediate plate 14 and has a pin hole for inserting the cylindrical pin 3, so that the cylindrical pin 3 is distributed below the intermediate plate 14.

[0031] Preferably, the linear bearing 5 is installed on the top plate 13 of the forward tilting part 12 via the flange seat 9, providing guidance and support for the upward and downward extension and retraction of the telescopic guide rod 2.

[0032] A bearing roller 7 is locked and installed at the top end of the telescopic guide rod 2 that passes upward through the linear bearing 5. Specifically, a shaft 8 is fixed at the top end of the telescopic guide rod 2, and the bearing roller 7 is installed through the shaft. Based on the bearing structure characteristics, the outer bushing of the bearing roller 7 is rotatable.

[0033] like Figure 3As shown, a concave groove 10 is formed on the outer bushing surface of the bearing roller 7 to better support the coil and prevent the coil from detaching from the bearing roller 7.

[0034] For example Figure 1 As shown, a spring 4 is fitted onto the telescopic guide rod 2, and the spring 4 is distributed between the retaining ring 6 and the intermediate plate 14. The retaining ring 6 is located near the heating position of the linear bearing on the telescopic guide rod. During the rotation of the winding mold 15, the different forces on the coil cause the bearing roller 7 to be stressed, which in turn acts on the telescopic guide rod 2. The downward movement of the retaining ring 6 on the telescopic guide rod 2 compresses the spring 4, and the tension of the spring 4 causes the telescopic guide rod 2 to spring back. Thus, as the coil mold 15 rotates, the telescopic rod continuously adjusts its distance through the extension and retraction of the spring, ensuring that the bearing roller is always in contact with the coil mold.

[0035] As a preferred option, such as Figure 4 As shown, the lower half of the telescopic guide rod 2 is cuboid in shape, and a square through hole is provided on the middle plate 14 for the cuboid rod to pass through, as shown. Figure 5 As shown, cuboid rods are distributed above and below the intermediate plate 14 to allow the telescopic rod 2 to reciprocate. Furthermore, the cuboid rods, in conjunction with the square through holes, also serve to prevent the telescopic guide rod 2 from rotating.

[0036] Therefore, the state of the high-voltage coil winding positioning device disclosed in this utility model when working in conjunction with the coil mold is as follows: Figure 4 As shown, the winding mold 15 is mounted on a square shaft 16, with both ends of the shaft pressed against the winding device to allow the winding mold 15 to rotate and wind the wire. The bearing roller 7 of the high-voltage coil winding positioning device is brought close to the furthest position of the winding mold 15, with the copper wire of the winding resting against the groove of the bearing roller 7. Then, the winding mold 15 is rotated. The telescopic guide rod 2 continuously adjusts the distance via spring extension and retraction as the winding mold 15 rotates, ensuring that the bearing roller 7 is always in contact with the coil mold. This novel coil winding positioning device replaces traditional manual marking, eliminating the possibility of errors during manual marking and reducing product defect rates.

[0037] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
