DETAILED DESCRIPTION

[0016] The following is a specific embodiment of the utility model and further describes the technical scheme of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.

[0017] As Figs. 1-2As shown, this embodiment includes a clamping tray 1, a fixing component 2, a gripper 3, and a drive motor. Clamping plates 11 are fixedly installed on both sides of the clamping tray 1. The gripper 3 is connected to one side of the drive motor. The gripper 3 achieves the clamping effect on the fixing component 2 and the clamping tray 1 by engaging with the outer side of the clamping plate 11. The fixing component 2 includes a first base plate 21, a second base plate 22, a magnetic fixing strip 23, a pressure plate 24, and a fixing collar 25.

[0018] Specifically, such as Figs. 1-2 As shown, the first base plate 21, the second base plate 22, and the pressure plate 24 are all ring structures. The first base plate 21 is placed on the upper end of the clamping tray 1. A fixing ring 212 is installed inside the first base plate 21, and the fixing ring 212 is fixedly connected to the clamping tray 1 to fix the first base plate 21 to the clamping tray 1. Several arc-shaped grooves 211 are opened on the first base plate 21, and fixing blocks 26 are fixed in the arc-shaped grooves 211. The number of magnetic fixing strips 23 is several and arranged in a circumferential array. The tail end of the magnetic fixing strip 23 is located at the upper end of the arc-shaped groove 211 and... The magnetic fixing strip 23 is fixedly connected to the first base plate 21 by bolts to the fixing block 26. The end of the magnetic fixing strip 23 extends out of the inner side of the first base plate 21. The second base plate 22 covers the upper end of the first base plate 21 and the magnetic fixing strip 23. The outer edge of the second base plate 22 has connecting teeth 221, which are in contact with the outer edge of the first base plate 21. The pressure plate 24 is installed on the upper end of the second base plate 22. The fixing collar 25 is connected to the inner side of the upper end of the second base plate 22 and is located inside the pressure plate 24.

[0019] To elaborate further, such as Figs. 1-2 As shown, a limiting groove 12 is provided on the front side of the clamping tray 1, and an extension block 213 is formed at the front end of the first base plate 21. A handle 214 is fixed on the extension block 213. The extension block 213 extends out of the limiting groove 12, and the first base plate 21 can be rotated by the handle 214.

[0020] To elaborate further, such as Figs. 1-2 As shown, the stator core is placed downwards through the fixing collar 25. The end of the magnetic fixing strip 23 extending out of the inner side of the first base plate 21 contacts the bottom end of the stator core. The magnetic field generated by the magnetic fixing strip 23 magnetizes the stator core, generating opposite magnetic poles, thereby firmly adsorbing the stator core to the working position in this embodiment. This adsorption method can provide a stable fixing force and can automatically align the position of the stator core to a certain extent.
