Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0017] Referring to Figures 1-4 , the present invention provides a lamination positioning device for laminated cores, including a workbench 1, on which a plurality of parallel support beams 2 are fixedly connected. The distance between adjacent support beams 2 is the same. Core laminations 3 are placed on the top of the support beams 2. Bottom plates 4 are respectively arranged on both sides of the core laminations 3. The bottom plates 4 are slidably connected to the support beam 2 located in the middle. A control component for controlling the movement of the two bottom plates 4 towards or away from each other is installed in the support beam 2 at the middle position. Corresponding top plates 5 are arranged on the bottom plates 4. The top plates 5 are arranged parallel to the bottom plates 4. A positioning component is installed between the bottom plates 4 and the top plates 5. An adjusting component for adjusting the height of the positioning component is installed between the top plates 5 and the bottom plates 4. By controlling the two bottom plates 4 to move towards each other through the control component, the two positioning components can be driven to move towards each other, which can be adjusted according to the size of the core laminations 3, facilitating the limitation of both sides of the core laminations 3, and then positioning them using the positioning component. The structure is stable and not prone to dislocation. The adjusting component can adjust the overall height of the positioning component, enabling it to be adjusted according to the lamination height to ensure the lamination effect.

[0018] In a specific embodiment, the control component includes a receiving groove 6 formed in a support beam 2 at the middle position. A push plate 7 is fixedly connected to one side of the bottom plate 4 away from the iron core laminations 3. The push plate 7 is slidably connected to the support beam 2. A protrusion that is slidably adapted to the receiving groove 6 is fixedly connected to the bottom of the push plate 7. A bidirectional threaded rod 8 is rotatably connected in the receiving groove 6. The two ends of the bidirectional threaded rod 8 have opposite thread directions. The bidirectional threaded rod 8 passes through both protrusions and is threadedly connected to the protrusions. The two push plates 7 are respectively located on both sides of the bidirectional threaded rod 8. One end of the bidirectional threaded rod 8 passes through the side wall of the receiving groove 6 and is fixedly connected to an adjustment knob 9. By driving the bidirectional threaded rod 8 to rotate through the adjustment knob 9, since the two ends of the bidirectional threaded rod 8 have opposite thread directions, the bidirectional threaded rod 8 will drive the two push plates 7 to move towards or away from each other through the protrusions when rotating, and then adjust the position of the positioning component through the bottom plate 4, so that the device can perform positioning work on iron core laminations 3 of different sizes.

[0019] In a specific embodiment, the positioning component includes an intermediate positioning plate 10 fixedly connected to the top plate 5 and two side positioning plates 11 fixedly connected to the bottom plate 4. The intermediate positioning plate 10 and the side positioning plates 11 are flush with the side of the bottom plate 4 close to the iron core laminations 3 at the same time. The two side positioning plates 11 are symmetrically arranged on both sides of the intermediate positioning plate 10. A plurality of moving positioning plates 12 are slidably connected between the intermediate positioning plate 10 and the side positioning plates 11. Both ends of the moving positioning plates 12 are respectively in contact with the top plate 5 and the bottom plate 4. Chute grooves 13 are formed on one side of the moving positioning plates 12 and the side positioning plates 11 close to the intermediate positioning plate 10. Square columns 14 are fixedly connected to both sides of the intermediate positioning plate 10 and the side of the moving positioning plates 12 facing the adjacent chute grooves 13. The square columns 14 are respectively slidably connected to the chute grooves 13, and the square columns 14 are located at the bottom of the chute grooves 13. The iron core laminations 3 can be positioned through the intermediate positioning plate 10, the side positioning plates 11 and the moving positioning plates 12. When the height of the laminations is higher than the top plate 5, the height of the top plate 5 can be adjusted through the adjusting component, and then the intermediate positioning plate 10 and the moving positioning plates 12 are pulled to move upward. At this time, the intermediate positioning plate 10, the side positioning plates 11 and the moving positioning plates 12 can still position the sides of the iron core laminations 3.

[0020] In a specific embodiment, the adjusting component includes a telescopic electric cylinder 15. The bottom end of the telescopic electric cylinder 15 is fixedly connected to the bottom plate 4, and the telescopic end of the telescopic electric cylinder 15 is fixedly connected to the top plate 5. The telescopic electric cylinder 15 is located at the side of the intermediate positioning plate 10. By driving the top plate 5 to move upward through the telescopic electric cylinder 15, the adjustment can be made according to the lamination height, so that the positioning component can always position the laminations. Specifically, the adjusting component can also adopt an existing lifting device to control the lifting of the top plate 5. This technology is a conventional technical means and will not be elaborated here.

[0021] Working process of the utility model: During use, adjust the positions of the two bottom plates 4 according to the width of the core laminations 3. Rotate the adjustment knob 9, and the adjustment knob 9 drives the bidirectional threaded rod 8 to rotate. Since the thread directions on both sides of the bidirectional threaded rod 8 are opposite, the two push plates 7 move towards each other, thereby driving the bottom plates 4 to move towards each other, so as to adjust the position of the positioning assembly, facilitating the positioning of the core laminations 3, and then laminating is carried out. When the lamination height is higher than the height of the top plate 5, start the telescopic electric cylinder 15. The telescopic electric cylinder 15 drives the top plate 5 to move upward. At the same time, the top plate 5 drives the intermediate positioning plate 10 and the moving positioning plate 12 to move upward, so that the intermediate positioning plate 10, the side positioning plate 11, and the moving positioning plate 12 can position the entire lamination with a certain height.
