Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer core lamination technology, and more specifically, to a lamination mechanism for transformer core production. Background Technology
[0002] Transformers are common devices that can transform AC voltage, current, and impedance. A transformer mainly consists of an iron core and coils. The iron core, as the main magnetic circuit part of the transformer, plays a role in conducting magnetism, allowing electrical energy to be converted into magnetic energy, and then back into electrical energy. During the production of transformer iron cores, multiple iron cores need to be stacked together for assembly. This process requires the use of appropriate lamination devices to assist manual lamination of the iron cores. However, existing technologies have the following shortcomings in their use:
[0003] The iron core usually has two through holes. When the iron core is placed on the workbench and the two uprights on the workbench are located in the two through holes, the iron core can be limited. However, the two uprights are usually fixed on the workbench and cannot be adjusted. They can only be used for a single type of iron core. If the two through holes are not on the same axis, it is difficult to stack multiple iron cores. This has certain limitations in practical use, low practicality, and is not conducive to practical promotion.
[0004] Therefore, there is an urgent need for a lamination mechanism for transformer core production to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to address the problem that existing iron cores typically have two through holes. When the iron core is placed on a workbench and the two uprights on the workbench are positioned within the two through holes, the iron core can be limited. However, the two uprights are often fixedly installed on the workbench and cannot be adjusted. This method can only accommodate a single type of iron core. If the two through holes are not on the same axis, it is difficult to stack multiple iron cores. This has certain limitations in practical use, resulting in low practicality and hindering its widespread adoption.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A lamination mechanism for transformer core production is proposed to improve the above-mentioned problems.
[0008] The application is as follows:
[0009] A lamination mechanism for transformer core production includes a worktable. Two fixed plates are fixedly connected to the top of the worktable, and a first guide rail is fixedly mounted on the top of both fixed plates. A connecting shaft is rotatably connected to the center of the top of the worktable via a bearing. A connecting block is fixedly connected to the top of the connecting shaft. A second guide rail is fixedly connected to one end face of the connecting block. Guide grooves and openings are provided on both the first and second guide rails. A slider is slidably connected in the guide groove. A vertical rod is fixedly connected to the top of the slider. A bearing plate is fixedly sleeved on the vertical rod. A threaded rod is fixedly connected to the slider. A limiting block is threadedly sleeved on the threaded rod. A rubber pad is fixedly connected to the limiting block. A plurality of positioning slots are provided on the top of the worktable. A positioning mechanism that mates with the positioning slots is provided on the end face of the second guide rail away from the connecting block. A support mechanism is provided at the bottom of the second guide rail.
[0010] As a preferred technical solution of this application, the positioning mechanism includes a fixing block fixedly connected to one end face of the second guide rail, an mounting block is provided directly below the fixing block, a guide rod passing through the fixing block is fixedly connected to the top of the mounting block, a spring located outside the guide rod is fixedly connected between the mounting block and the fixing block, and a positioning insert rod located in one of the positioning slots is fixedly connected to the bottom of the mounting block.
[0011] As a preferred technical solution of this application, the support mechanism includes a fixed shaft fixedly connected to the bottom of the second guide rail, and a pulley is installed at the bottom of the fixed shaft, with the pulley in contact with the top surface of the worktable.
[0012] As a preferred technical solution of this application, a plurality of the positioning slots are arranged in an arc shape at equal angles, and the positioning rod is adapted to the positioning slots.
[0013] As a preferred technical solution of this application, the first guide rail and the second guide rail have the same specifications, and the two bearing plates are respectively attached to the first guide rail and the second guide rail.
[0014] As a preferred technical solution of this application, the two openings are respectively connected to two guide grooves, and the two threaded rods are respectively located in the two openings.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] In the scheme of this application:
[0017] 1. By pulling the two uprights, the two sliders slide in the two guide grooves respectively, and the position of the two uprights can be adjusted. By rotating the two limit blocks, the two rubber pads are made to fit with the first guide rail and the second guide rail respectively, which can position the two uprights. At the same time, after pulling the mounting block upward, the adjustment range of the uprights can be increased by rotating the second guide rail, which is convenient to adapt to different types of iron cores and facilitates practical promotion.
[0018] 2. By cooperating with the positioning slot, the second guide rail can be positioned. After the second guide rail is adjusted, it can be prevented from rotating, which facilitates the subsequent lamination of the iron core. Attached Figure Description

[0031] Example:
[0032] like Figure 1-5As shown, this embodiment proposes a lamination mechanism for transformer core production, including a workbench 1. Two fixed plates 2 are fixedly connected to the top of the workbench 1. A first guide rail 3 is fixedly mounted on the top of both fixed plates 2. A connecting shaft 4 is rotatably connected to the center of the top of the workbench 1 via a bearing. A connecting block 5 is fixedly connected to the top of the connecting shaft 4. A second guide rail 6 is fixedly connected to one end face of the connecting block 5. Guide grooves 7 and openings 8 are provided on both the first guide rail 3 and the second guide rail 6. A slider 9 is slidably connected within the guide groove 7. A vertical rod 10 is fixedly connected to the top of the slider 9. Pulling the two vertical rods 10 causes the two sliders 9 to slide within the two guide grooves 7 respectively. The vertical rods 10 are fixedly connected to... The fixed sleeve is equipped with a bearing plate 11, and a threaded rod 12 is fixedly connected to the slider 9. The two threaded rods 12 move synchronously with the two sliders 9 respectively. A limit block 13 is threaded on the threaded rod 12. After the two uprights 10 are pulled to the appropriate position, the two limit blocks 13 are rotated. A rubber pad 14 is fixedly connected to the limit block 13, so that the two rubber pads 14 are respectively in contact with the first guide rail 3 and the second guide rail 6, thereby fixing the two sliders 9 and the two uprights 10. Several positioning slots 15 are opened on the top of the worktable 1. The end face of the second guide rail 6 away from the connecting block 5 is provided with a positioning mechanism that cooperates with the positioning slots 15. A support mechanism is provided at the bottom of the second guide rail 6.
[0033] like Figure 1 and Figure 2 As shown, the positioning mechanism includes a fixing block 16 fixedly connected to one end face of the second guide rail 6. A mounting block 17 is provided directly below the fixing block 16. A guide rod 18 is fixedly connected to the top of the mounting block 17, passing through the fixing block 16. A spring 19 located outside the guide rod 18 is fixedly connected between the mounting block 17 and the fixing block 16. A positioning insert 20 located in one of the positioning slots 15 is fixedly connected to the bottom of the mounting block 17. Pulling the mounting block 17 upward causes the positioning insert 20 to disengage from the positioning slot 15. Then, the second guide rail 6 is rotated to a suitable position. Then, the mounting block 17 is released, and the elastic force of the spring 19 drives the mounting block 17 to move downward, so that the positioning insert 20 is inserted into the corresponding positioning slot 15, thereby fixing the second guide rail 6 and completing the adjustment of the two uprights 10, which is beneficial for practical use.
[0034] like Figure 1 and Figure 4 As shown, the support mechanism includes a fixed shaft 21 fixedly connected to the bottom of the second guide rail 6. A pulley 22 is installed at the bottom of the fixed shaft 21. The pulley 22 is in contact with the top surface of the workbench 1. Through the fixed shaft 21 and the pulley 22, in conjunction with the connecting shaft 4, the support effect on the second guide rail 6 can be guaranteed, which facilitates the subsequent stacking of multiple iron cores.
[0035] like Figure 2 and Figure 5As shown, several positioning slots 15 are arranged in an arc at equal angles. The positioning rod 20 is adapted to the positioning slots 15. By cooperating with the positioning slots 15, the second guide rail 6 can be fixed.
[0036] like Figure 1 and Figure 3 As shown, the first guide rail 3 and the second guide rail 6 have the same specifications, and the two bearing plates 11 are respectively attached to the first guide rail 3 and the second guide rail 6.
[0037] like Figure 1 and Figure 3 As shown, the two openings 8 are connected to the two guide grooves 7 respectively, and the two threaded rods 12 are located in the two openings 8 respectively.
[0038] Specifically, when using the lamination mechanism for transformer core production: The operator pulls the two uprights 10 according to the actual positions of the two through holes on the core, causing the two sliders 9 to slide within the two guide grooves 7 respectively. The two threaded rods 12 move synchronously with the two sliders 9. After pulling the two uprights 10 to the appropriate position, the two limiting blocks 13 are rotated, causing the two rubber pads 14 to engage with the first guide rail 3 and the second guide rail 6 respectively, thus fixing the two sliders 9 to the two uprights 10. Then, the mounting block 17 is pulled upwards to position the insertion rod. The positioning rod 20 is disengaged from the positioning slot 15, and the second guide rail 6 is rotated to the appropriate position. Then, the mounting block 17 is released, and the mounting block 17 is moved downward by the elastic force of the spring 19, so that the positioning rod 20 is inserted into the corresponding positioning slot 15, thereby fixing the second guide rail 6 and completing the adjustment of the two uprights 10. Finally, multiple iron cores are sequentially sleeved on the two uprights 10 to realize the stacking of iron cores. The overall structure is simple and ingenious, with low production cost, and can adapt to different types of iron cores, making it more practical and conducive to actual promotion.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
