Background In the field of small motor manufacturing, a stator core is used as one of core components of a motor, and the manufacturing quality and efficiency of the stator core directly influence the performance and production cost of the motor. The stator core is generally formed by stacking a plurality of silicon steel sheets, and the silicon steel sheets are mutually attached through a specific process so as to form a core structure with good electromagnetic performance. However, the existing stator core fixing device of the small motor has a plurality of problems in practical application, and severely restricts the manufacturing efficiency and quality of the stator core. In the existing stator core fixing device, dislocation is extremely easy to occur in the stacking process of silicon steel sheets. This is due to the lack of efficient positioning and guiding mechanisms in the structural design of existing fixtures.

Once the sheet is misaligned, it is then necessary to adjust it. Not only does this increase the workload of the worker, but the adjustment process is often cumbersome. The worker needs to carefully check the position of each sheet of silicon steel and then fine-tune it using a special tool to ensure that all sheets of silicon steel are properly aligned.
