[0046] like Figures 1 to 4 As shown, two clamping jaws 1 are arranged opposite to each other; the outer bracket 2 is arranged on both clamping jaws 1, and the two outer brackets 2 have clamping plates 21 extending to opposite sides, and the clamping plates 21 are used to support the end surface of the stator; the first gasket 3 is arranged on the clamping jaw 1; the second gasket 4 is arranged on the surface of the clamping plate 21 close to the clamping jaw 1; the driving member 5 is used to drive the two clamping jaws 1 to move relative to each other;

[0047] As in the above structure, when clamping the stator, the driving member 5 is used to drive the jaws 1 to open and close, the first gasket 3 on the inner side of the jaws 1 is used to contact the circumferential surface of the stator, and the clamping plate 21 of the outer bracket 2 is used to support the end surface of the stator 100. In order to prevent the stator 100 from being damaged, a second gasket 4 is provided on the clamping plate 21 for buffering protection; in this way, the clamp can firmly clamp the stator 100, and it is not affected by the irregular inner hole of the stator 100 and the installation of parts, and has the advantage of a wide range of adaptability.

[0048] like Figure 3 As shown, the clamping jaw 1 is in a U-shaped structure, the first gasket 3 is arranged in the opening of the clamping jaw 1, and the first gasket 3 is provided with a trapezoidal groove;

[0049] As in the above structure, by setting the clamping jaw 1 to be U-shaped, the first gasket 3 can be positioned during assembly, and a trapezoidal groove is provided on the first gasket 3, which can better fit the surface of the stator 100.

[0050] like Figure 3 and Figure 4 As shown, the edge of the clamping plate 21 away from the outer bracket 2 is in an arc shape;

[0051] As in the above structure, by setting the edge of the clamping plate 21 to be in an arc shape, it can fit the surface of the stator to achieve stable clamping.

[0052] like Figure 3 As shown, the outer bracket 2 and the clamping plate 21 are arranged at an angle, and each clamping jaw 1 is provided with two outer brackets 2 and two clamping plates 21; the clamping jaw 1 is connected to the outer bracket 2 by bolts;

[0053] As in the above structure, since the stator 100 has various models, the outer bracket 2 is mounted on the clamping jaw 1 by bolts, so as to adapt to different models of stators 100 by replacing the clamping jaw 1, thereby improving the clamping adaptability range.

[0054] like Figure 2 As shown, the driving member 5 includes a mounting frame 51 and a linear driving mechanism 52, wherein the linear driving mechanism 52 is arranged on the mounting frame 51, and a clamping claw 1 is arranged on the movable end of the linear driving mechanism 52; a clamping claw 1 is also arranged on the side of the mounting frame 51 away from the movable end of the linear driving mechanism 52;

[0055] As in the above structure, the mounting frame 51 is used as the mounting base, so the linear drive mechanism 52 can be directly installed on the mounting frame 51, and then a clamp 1 can be installed on the movable end of the mounting frame 51 and the linear drive mechanism 52 respectively. When the linear drive mechanism 52 is in motion, the two clamps 1 are relatively opened and closed.

[0056] like Figure 2 As shown, the mounting frame 51 is a rectangular frame structure, and the mounting frame 51 has a first chamber 501 and a second chamber 502 adjacent to each other; one side of the second chamber 502 is open, and the linear drive mechanism 52 is disposed in the second chamber 502, and the movable end of the linear drive mechanism 52 extends out through the opening;

[0060] As in the above structure, the suspension 6 is used to connect the lifting equipment to realize the lifting work. After the stator 100 is clamped by the clamp, the clamp is driven to rotate by the rotating cylinder 8 through the driving shaft 9, thereby realizing the flipping work of the stator 100.

[0062] As shown in the above structure, the control box 10 is used for the electrical control of the sling, and it can also be used for the electrical control of the lifting equipment. The armrest 11 is used to adjust the position of the sling, and the armrest 11 can integrate switches electrically connected to the clamp, sling and lifting equipment to control the movement of the components.

[0063] Specific implementation steps:

[0064] First, the linear drive mechanism 52 is used to drive the clamp 1 to move and clamp the stator 100. During clamping, the first gasket 3 abuts against the circumferential surface of the stator 100, and the second gasket 4 abuts against the end surface of the stator 100. After stable support is achieved, the handrail 11 is used to drive the hanger to move. After the stator 100 moves to a suitable position, the rotating cylinder 8 drives the clamp and the stator 100 to flip together through the drive shaft 9. After the angle is adjusted, the stator 100 can be placed.
