[0023] In the following description, embodiments of the transformer silicon steel sheet stacking fixture of the present invention will be described with reference to the accompanying drawings.
[0024] Figures 1-4This invention illustrates a transformer silicon steel sheet stacking fixture according to an embodiment of the present invention. It includes a mounting slide 2 fixedly mounted on the top of a silicon steel sheet stacking moving platform 1. A connecting plate 3 is slidably connected to the top of the mounting slide 2. Four rails 5 are provided on the top of the connecting plate 3. Four fixing blocks 4 are fixedly connected to the top of the connecting plate 3. The tops of the four fixing blocks 4 are fixedly connected to the bottoms of the rails 5. Through the cooperation of the fixing blocks 4 and the rails 5, when the moving plate 6 slides on the top of the rails 5, the fixing blocks 4 limit the movement of the moving plate 6 on the rails 5, ensuring that the moving plate 6 remains within the rails. When the top of track 5 slides, track 5 will not move at the top of connecting plate 3, improving the stability of track 5 during use. Each of the four tracks 5 has a sliding plate 6 slidably connected to its top. A rotating column 7 is fixedly connected to the opposite side of the bottom of each of the four moving plates 6. A rotating disk 8 is located at the central axis of the top of connecting plate 3, and the rotating column 7 is rotatably connected to the rotating disk 8. A cylinder 11 is installed at the bottom of connecting plate 3, and a connecting block 9 is fixedly connected to the central axis of the top of connecting plate 3. The top of the connecting block 9 is rotatably connected to the rotating disk 8. The output end of cylinder 11... At the central axis of the connecting block 9, the rotating disk 8 and the connecting block 9 work together. When the rotating disk 8 rotates on top of the connecting block 9, the connecting block 9 guides the rotating disk 8, ensuring that the moving plate 6 slides stably when the rotating column 7 is rotated by the rotating disk 8, thus improving the stability of the rotating column 7 during rotation. The output end of the cylinder 11 extends to the top of the connecting plate 3 and is fixedly connected to the rotating disk 8. A fixing sleeve 10 is fixedly connected to the central axis at the bottom of the connecting plate 3, and the cylinder 11 is fixedly installed in the fixing sleeve 10. The inner cavity, through the setting of the fixing sleeve 10, plays a supporting role for the cylinder 11, ensuring that the cylinder 11 will not detach from the connecting plate 3 when the connecting plate 3 moves, thus improving the stability of the cylinder 11 during use. The top of the four moving plates 6 on opposite sides are all fixedly connected with clamping plates 12. The top of the connecting plate 3 is fixedly connected with multiple support legs 13, and the top of the multiple support legs 13 is fixedly connected with a placement plate 14. The top of the rotating disc 8 is provided with an arc-shaped groove for the rotating column 7 to rotate. The top of the placement plate 14 is tightly fitted with the transformer silicon steel sheet.
[0025] Working Principle: In use, the user stacks the transformer silicon steel sheets one by one on top of the placement tray 14. At this time, the cylinder 11 inside the fixing sleeve 10 is activated. The output end of the cylinder 11 drives the rotating disk 8 to rotate via the connecting block 9. The rotating disk 8 then rotates on top of the connecting block 9, causing the rotating column 7 within the arc-shaped groove to rotate. This causes the rotating column 7 to move the moving plate 6 to slide on the surface of the track 5. Then, the four moving plates 6 slide towards each other on top of the connecting plate 3, thereby moving... The moving plate 6 will drive the clamping plate 12 to slide towards each other, so that the clamping plate 12 will clamp the transformer silicon steel sheet on the top of the placement tray 14. Due to the setting of the clamping plate 12, the clamping plate 12 will not damage the four sides of the transformer silicon steel sheet when clamping it, which improves the quality of the transformer silicon steel sheet during stacking, and thus makes the transformer silicon steel sheet neat on the top of the placement tray 14. Finally, the silicon steel sheet stacking moving table 1 and the installation slide 2 will drive the connecting plate 3 to move, and the user will take out the neat transformer silicon steel sheet from the top of the placement tray 14.
[0026] In summary, this transformer silicon steel sheet stacking fixture, by stacking the transformer silicon steel sheets one by one on the top of the placement disk 14, and then through the coordinated use of the moving plate 6, rotating column 7, and rotating disk 8, causes the moving plate 6 to drive the clamping plates 12 to move towards each other, thereby clamping the four sides of the transformer silicon steel sheets on the top of the placement disk 14. This achieves the purpose of using a rotating internal support clamping structure, ensuring that the four sides of the transformer silicon steel sheets are neatly clamped after stacking, and that the silicon steel sheets are neatly stacked without deviation. This ensures that the magnetic circuit is completely distributed according to the design path, with good continuity and uniformity of the magnetic circuit, and ensures that the insulation spacing between the iron core and the winding is uniform, thus improving the stacking quality of the transformer silicon steel sheets.
