Description

Technical Field

[0001] This utility model relates to the field of transformer coil manufacturing technology, specifically a copper busbar positioning device for foil-wound coils. Background Technology

[0002] Low-voltage transformer coils often use foil winding, especially in dry-type transformers. During coil winding, copper foil is soldered onto copper busbars. To save on copper busbar usage, the soldered portion between the busbar and the foil is often beveled. This makes positioning the copper busbars on the mold difficult, resulting in the start and end of the finished coil not being perfectly aligned, affecting the overall product quality.

[0003] If fixed iron strips are used for positioning, the upper and lower copper busbars will still not align because they cannot be adjusted. Furthermore, the width and angle of the copper busbars vary for different product specifications, requiring multiple positioning blocks to match them. This necessitates frequent replacement of positioning blocks, which severely impacts production efficiency and product consistency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the existing technology and provide a foil-wound coil copper busbar positioning device with simple structure, flexible adjustment and adaptability to various specifications of copper busbars, so as to solve the problems of inconvenient adjustment and poor versatility of traditional positioning devices.

[0005] To solve the above-mentioned technical problems, this utility model provides a copper busbar positioning device for foil winding coils, comprising: a fixed plate, a positioning block, a pin, an adjusting shaft, a bushing, a locking nut, and an adjusting nut; the lower end of the fixed plate is fixed to the winding mold by bolts, and the upper end is connected to one end of the adjusting shaft by the bushing; one end of the adjusting shaft is hinged to the positioning block, the other end is threaded to the locking nut, and the middle part is threaded to the adjusting nut, and the adjusting shaft is controlled by the adjusting nut to move its axial linear motion; the contact surface between the positioning block and the copper busbar is an inclined surface.

[0006] Further optimization involves a vertical Z-shaped structure with a through hole on the upper surface and an elongated hole on the lower surface.

[0007] In a further optimization, the bushing is fixedly installed inside the through hole, and the inner diameter of the bushing is larger than the diameter of the adjusting shaft.

[0008] Further optimization involves a portion of the adjusting shaft being a threaded screw structure and another portion being a semi-circular flat connecting block; one end of the semi-circular flat connecting block is provided with a connecting hole.

[0009] Further optimization involves providing a semi-circular open limiting groove at the connection between the semi-circular flat connecting block and the positioning block.

[0010] Further optimization involves making the positioning block a T-shaped structure from steel plate, with the hinged part hinged to the adjusting shaft via a pin, and the positioning part fitting against the inclined surface of the copper busbar via one side of the inclined surface.

[0011] The beneficial effects of this utility model are as follows: 1. Adjustable positioning structure: The positioning block slides along the inclined surface of the copper busbar by adjusting the telescopic control of the shaft, adapting to different inclined surface angles; 2. Versatile design: The hinged design of the T-shaped positioning block and the adjusting shaft is compatible with various specifications of copper busbars; 3. Quick locking mechanism: Combining the adjusting nut and the locking nut, the position of the copper busbar is accurately fixed and dynamically calibrated.

[0012] This invention features a simple structure, flexible adjustment, and compatibility with various copper busbar specifications. Through an adjustable screw mechanism and hinged positioning block design, it achieves rapid alignment and fixation of the copper busbar's inclined surface. The device is suitable for copper busbars of different specifications, significantly improving positioning accuracy and production efficiency, and solving the technical problem of poor adaptability of traditional fixed positioning blocks.

Detailed Implementation

[0014] The present invention will now be described in detail with reference to the accompanying drawings.

[0015] like Figure 1-5 As shown, the foil-wound coil copper busbar positioning device of this utility model includes: a fixing plate 1, a positioning block 2, a pin 3, an adjusting shaft 4, a bushing 5, a locking nut 6, and an adjusting nut 7; The lower end of the fixed plate is fixed to the winding mold 8 by bolts, and the upper end is connected to one end of the adjusting shaft by a bushing; one end of the adjusting shaft 4 is hinged to the positioning block 2, the other end is threaded to the locking nut 6, and the middle part is threaded to the adjusting nut 7. The adjusting shaft 4 is controlled to move linearly in the axial direction by the adjusting nut 7; the contact surface between the positioning block 2 and the copper busbar 9 is an inclined surface.

[0016] The adjustable screw mechanism and hinged positioning block design enable rapid alignment and fixation of the copper busbar's inclined surface. The device is suitable for copper busbars of different specifications, significantly improving positioning accuracy and production efficiency, and solving the technical problem of poor adaptability of traditional fixed positioning blocks.

[0017] In this embodiment, the fixing plate 1 has a vertical Z-shaped structure with a through hole on the upper surface and an elongated hole on the lower surface; the through hole is welded to the bushing, and the elongated hole is fixed to the winding mold 8 by bolts.

[0018] In this embodiment, the bushing 5 is a tubular shape machined from round steel, with a length of 10mm. The inner diameter of the bushing is 0.5mm larger than the diameter of the adjusting shaft.

[0019] In this embodiment, part of the adjusting shaft 4 is a threaded screw structure, and the other part is a semi-circular flat connecting block; one end of the semi-circular flat connecting block is provided with a connecting hole; a semi-arc-shaped open limiting groove is provided at the connection between the semi-circular flat connecting block and the positioning block, which mainly serves to limit the positioning block after it is attached to the copper busbar, so that the positioning block and the copper busbar are more tightly attached.

[0020] In this embodiment, the positioning block 2 is a T-shaped structure made of steel plate. The hinge part is hinged to the adjusting shaft by a pin, and the positioning part is attached to the inclined surface of the copper busbar by one side of the inclined surface.

[0021] The working principle or process of this utility model: Combined with appendix Figure 1-4 The detailed process is as follows: The mold is insulated, and the first end of the copper busbar is placed against the baffle. The inclined surface of the positioning block is placed against the inclined surface of the copper busbar, with its lower surface pressed firmly against the mold. The adjusting nut is rotated to move the positioning block to the lower end of the copper busbar. The bolts connecting the positioning plate and the mold are tightened. The adjusting nut is then rotated to move the adjusting shaft forward, causing the positioning block to slide forward along the inclined surface of the copper busbar, thus securing the copper busbar. Simultaneously, the tail end of the copper busbar can be finely adjusted to ensure its edge is parallel to the mold. Finally, the locking nut is tightened. This completes the positioning and copper busbar alignment process by keeping the positioning device stationary.

[0022] During winding, the copper busbar may shift at the tail due to the tension of the copper foil. In this case, rotating the adjusting nut will correct the horizontal position of the copper busbar. For copper busbars of different widths, the position of the elongated hole at the bottom of the positioning plate can be adjusted to accommodate busbars with significantly different widths.

[0023] This invention features a simple structure, flexible adjustment, and compatibility with various copper busbar specifications. Through an adjustable screw mechanism and hinged positioning block design, it achieves rapid alignment and fixation of the copper busbar's inclined surface. The device is suitable for copper busbars of different specifications, significantly improving positioning accuracy and production efficiency, and solving the technical problem of poor adaptability of traditional fixed positioning blocks.

[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
