Abstract
Description
Technical Field
[0001] This application relates to the field of transformer manufacturing technology, specifically to a movable and adjustable iron core positioning device. Background Technology
[0002] In the core stacking process of electromagnetic components such as transformers and chargers, traditional methods rely on specialized positioning templates with fixed column arrays to achieve precise lamination of silicon steel sheets or amorphous alloy sheets. Specifically, during operation, core materials are fitted one by one onto the fixed columns of the template, and positioning is achieved through the matching relationship between the columns and the openings in the core, ultimately forming a closed magnetic circuit with aligned layers. However, this method has the following significant drawbacks:
[0003] 1. Low Template Universality: The core dimensions, lamination shapes, and positioning hole distributions of different product specifications vary greatly. Each new product requires a uniquely designed and manufactured template. The template needs precision machining (such as CNC cutting and EDM) to ensure micron-level dimensional tolerances for the fixing columns, resulting in a single template costing tens of thousands of yuan. For multi-variety, small-batch orders, the template cost can even exceed the material cost of the core itself.
[0004] Second, the production preparation cycle is lengthy: From product design finalization to template delivery, multiple stages are required, including structural surveying, 3D modeling, machining programming, and trial production verification. The development cycle for a single template typically takes 20-40 working days. Especially for irregularly shaped iron cores or composite laminated structures, the layout of template positioning columns often needs to be repeatedly revised, further delaying the mass production process.
[0005] The aforementioned pain points force companies into a vicious cycle of "high R&D investment and slow order response," which in particular restricts the demand for high-frequency product iteration in emerging fields such as new energy and customized power supplies. Utility Model Content
[0006] In view of the above problems, this application provides a movable and adjustable iron core positioning device to solve the technical problem of low versatility of the above-mentioned iron core fixing device.
[0007] To achieve the above objectives, this application provides a movable and adjustable iron core positioning device for fixing the iron core during iron core installation, comprising:
[0008] A substrate for placing the iron core, the upper surface of the substrate is provided with a plurality of parallel transverse grooves and at least one longitudinal groove, the longitudinal groove being perpendicular to the transverse grooves;
[0009] At least one additional slide groove is detachably disposed on the upper surface of the substrate, and one end is slidably disposed in the transverse slide groove, while the other end faces the adjacent transverse slide groove.
[0010] Multiple fixing rods are disposed on the upper surface of the substrate, and their bottoms are slidably disposed within the transverse groove, the longitudinal groove, and the additional groove. The fixing rods are used to abut against the side of the iron core to define the position of the iron core on the substrate.
[0011] Furthermore, a rotating engagement part and a locking part are provided at the bottom of one end of the additional slide groove. The rotating engagement part is cylindrical and its diameter is smaller than the width of the transverse slide groove, so that the additional slide groove can rotate and slide within the transverse slide groove. The locking part is provided at the end of the rotating engagement part and is used to lock the position of the rotating engagement part within the transverse slide groove.
[0012] Furthermore, the bottom of the fixing rod is provided with a sliding joint and a locking nut. The thickness of the sliding joint is less than the width of the transverse sliding groove, and the width of the sliding joint is greater than the width of the transverse sliding groove. The locking nut is threaded to the end of the sliding joint to tighten the position of the sliding joint within the transverse sliding groove.
[0013] Furthermore, the top of the fixing rod is provided with an arc-shaped guide portion.
[0014] Furthermore, the longitudinal groove is provided at least on the outer edge of the substrate.
[0015] Furthermore, the longitudinal groove consists of two or more grooves arranged intermittently.
[0016] Furthermore, a scale is provided at least along the length of the transverse groove.
[0017] Furthermore, the upper surface of the substrate is provided with two or more magnets, which are arranged adjacent to the fixing rod for magnetically attracting the iron core.
[0018] Unlike existing technologies, the movable and adjustable iron core positioning device described above includes a base plate and a transverse slide groove, a longitudinal slide groove, and an additional slide groove disposed on the base plate. A fixing rod is slidably disposed within the transverse slide groove, the longitudinal slide groove, and the additional slide groove. The multiple transverse slide grooves are arranged parallel to each other, and the longitudinal slide groove is perpendicular to the transverse slide groove. The additional slide groove is detachably disposed within the transverse slide groove. The position and angle between the additional slide groove and the transverse slide groove can be adjusted as needed. Therefore, by adjusting the position of the fixing rod on the base plate, it can be applied to iron cores of various sizes and shapes, greatly improving the versatility of the positioning device.

[0041] Please see Figures 1 to 5 This embodiment provides a movable and adjustable iron core positioning device 1. This movable and adjustable iron core positioning device 1 allows for more flexible setting of the position of the fixing rod 13 on the substrate 11, thus making it applicable to iron cores 20 of more sizes and shapes. The iron core 20 is a sheet-like metal structure used in electromagnetic components such as transformers and chargers. During the production process of transformers and chargers, the sheet-like iron cores 20 need to be stacked layer by layer to form a large iron core with a certain height. The winding wires in the transformer and charger are wound around the outside of this large iron core. In this embodiment, the movable and adjustable iron core positioning device is used to fix the iron core 20 during the assembly process. The movable and adjustable iron core positioning device can be applied to manual assembly of large iron cores or to iron core 20 stacking equipment.
[0042] like Figure 1 As shown, in this embodiment, the movable and adjustable iron core positioning device includes: a base plate 11, a plurality of fixing rods 13 and at least one additional slide groove 14.
[0043] The base plate 11 is used to place the iron core 20, and the base plate 11 is the main body of the movable and adjustable iron core positioning device. The base plate 11 can be made of steel plate, aluminum alloy plate, etc. The iron core 20 is assembled by stacking on the upper surface of the base plate 11. The upper surface of the base plate 11 is provided with multiple parallel transverse sliding grooves 121 and at least one longitudinal sliding groove 122, the longitudinal sliding groove 122 being perpendicular to the transverse sliding grooves 121. Figure 1 As shown, a longitudinal groove 122 is provided on the outer edge of the substrate 11. The longitudinal groove 122 is composed of two or more grooves 12 arranged intermittently.
[0044] The additional slide 14 is detachably disposed on the upper surface of the substrate 11, and one end of the slide 14 is disposed in the transverse slide 121, while the other end faces the adjacent transverse slide 121.
[0045] The fixing rod 13 is disposed on the upper surface of the substrate 11, and its bottom is slidably disposed in the transverse groove 121, the longitudinal groove 122 and the additional groove 14. The fixing rod 13 is used to abut against the side of the iron core 20 to limit the position of the iron core 20 on the substrate 11.
[0046] like Figure 1 As shown, in this embodiment, at least eight transverse sliding grooves 121 are provided on the substrate 11, and a longitudinal sliding groove 122 is provided on the left side of the substrate 11; and four additional sliding grooves 14 are provided. Each additional sliding groove 14 has a groove 141 with the same width as the transverse sliding grooves 121 and the longitudinal sliding groove 122, therefore the bottom of the fixing rod 13 can be applied to the transverse sliding grooves 121, the longitudinal sliding groove 122, and the additional sliding grooves 14. Figure 4 As shown, the number of transverse grooves 121 and longitudinal grooves 122 is fixed after the substrate 11 is formed, but the number of additional grooves 14 can be increased or decreased as needed. In this embodiment, fixing rods 13 can be provided in all or some of the transverse grooves 121 as needed, and the position of the fixing rods 13 can be adjusted. Appropriate additional grooves 14 can be selected as needed, and the position of the additional grooves 14 on the transverse grooves 121 can be adjusted, so that fixing rods 13 can also be provided in the area between two adjacent transverse grooves 121. The substrate is provided with two or more mounting holes 15, through which the substrate can be mounted on a core lamination device or other support platform.
[0047] like Figure 2 As shown, the position of the fixing rod 13 can be adjusted according to the shape and size of the iron core 20, so that different fixing rods 13 abut against the sides of different positions of the iron core 20, thereby stably fixing the iron core 20 to the base plate 11, so that the iron core 20 can only move vertically, while being completely restricted in the horizontal direction by each fixing rod 13. Therefore, this movable and adjustable iron core positioning device can be applied to fixing various types of iron cores 20, and, as Figure 3 As shown, the fixing rod 13 can be set at any position in the area between two adjacent transverse slides 121 by means of the additional slide 14, thus greatly reducing the number of transverse slides 121.
[0048] like Figure 4 As shown, in this embodiment, the bottom of the fixing rod 13 is provided with a sliding part 132 and a locking nut 134. The thickness of the sliding part 132 is less than the width of the transverse sliding groove 121, thereby allowing the fixing rod 13 to be slidably connected to the transverse sliding groove 121. The width of the sliding part 132 is greater than the width of the transverse sliding groove 121; the end of the sliding part 132 is provided with a connecting thread 133, which is adapted to the locking nut 134. The locking nut 134 is threadedly connected to the end of the sliding part 132 to tighten the position of the sliding part 132 within the transverse sliding groove 121. Because the width of the sliding part 132 is greater than the width of the transverse sliding groove 121, the fixing rod 13 cannot rotate within the transverse sliding groove 121, but can only slide to adjust its position. After the position is adjusted, the fixing rod 13 can be fixed by tightening the locking nut 134.
[0049] like Figure 5 As shown, the bottom of one end of the auxiliary slide groove 14 is provided with a rotating engagement portion 142 and a locking portion 143. The rotating engagement portion 142 is cylindrical, and its diameter is smaller than the width of the transverse slide groove 121, allowing the auxiliary slide groove 14 to rotate and slide within the transverse slide groove 121. The locking portion 143 is located at the end of the rotating engagement portion 142 and is used to lock the position of the rotating engagement portion 142 within the transverse slide groove 121. Specifically, the locking portion 143 can be a lock nut. The locking portion 143 is threadedly connected to the end of the rotating engagement portion 142.
[0050] like Figure 4 As shown, in this embodiment, the top of the fixing rod 13 is provided with an arc-shaped guide portion 131. The arc-shaped guide portion 131 can facilitate the placement of the iron core 20 into the position defined by each fixing rod 13, and can prevent the top of the fixing rod 13 from scratching the surface of the iron core 20.
[0051] In some embodiments, in order to facilitate the adjustment of the position of the fixing rod 13 on the transverse slide 121, a scale is provided in the length direction of the transverse slide 121.
[0052] like Figure 1 As shown, the upper surface of the substrate 11 is provided with two or more magnets 16, which are arranged adjacent to the fixing rod 13 and are used to magnetically attract the iron core 20. The magnets 16 can be high-permeability magnets such as neodymium iron boron magnets and samarium cobalt magnets.
[0053] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
