Abstract
Description
Technical Field
[0001] This utility model belongs to the field of iron core lamination technology, and particularly relates to a device for laminating iron core laminations of permanent magnet motors. Background Technology
[0002] Permanent magnet motor laminations are typically circular in design. During use, they are clamped together using stacked silicon steel sheets, and finally formed into a rotor through stamping or welding. Permanent magnet motor cores come in many models, each with a different core radius. Currently, each size of core lamination has its own dedicated lamination mold. Different core sizes require different radii for the lamination mandrel used in the mold, and the lamination mold needs to be changed when the motor core size changes.
[0003] In the prior art, patent CN210536461U discloses a lamination stacking mechanism for permanent magnet motors. This technical solution achieves autonomous clamping of laminations through a clamping drive, ensuring the positioning of the laminations. The size of the laminations can be changed autonomously by adjusting the clamping drive, without the need for manual screw adjustment. However, during use, the upper pressure plate of this stacking device cannot be adjusted adaptively, requiring the replacement of pressure plates of different specifications, which is detrimental to the lamination stacking operation.

[0012] Beneficial effects

A second electric telescopic rod 14 is provided on the fixing plate 13. A pressing plate 15 is fixedly connected to the bottom of the second electric telescopic rod 14. The side wall of the pressing plate 15 is provided with several pressing arc plates 18 that can be pulled out and moved.
[0023] After the transmission mechanism is working, the distance between multiple positioning clamps 10 can be adjusted to adapt to different specifications of punches for positioning. After the pressing arc plate 18 is pulled and moved, the pressing area can be adjusted to adapt to different specifications of punches for stacking work.
[0024] After the stacking is completed, the lifting plate 5 can be driven down by the drive mechanism, and the lifting plate 5 can drive multiple positioning clamps 10 down, reducing the space occupied by the positioning clamps 10, which facilitates the subsequent material handling operation after the stacking is completed, and is beneficial to the production and processing of permanent magnet motor cores.
[0025] Furthermore, the drive mechanism includes a motor 2, which is fixedly connected to the upper part of the inner cavity of the housing 1. The output shaft of the motor 2 is fixedly connected to a threaded rod 3, the bottom end of which is rotatably connected to the bottom of the inner wall of the housing 1. A threaded sleeve 4 is threadedly connected to the surface of the threaded rod 3, and the threaded sleeve 4 is fixedly connected to the side wall of the lifting plate 5.
[0026] In this embodiment, after the motor 2 drives the threaded rod 3 to rotate, the threaded sleeve 4 can drive the lifting plate 5 to move up and down. Multiple sets of drive mechanisms can be set.
[0027] Furthermore, a guide rod 6 is vertically fixedly connected to the bottom of the inner wall of the container 1, and the lifting plate 5 is slidably sleeved on the surface of the guide rod 6.
