[0025] It should be noted that both the upper top head 7 and the lower top head 8 are cylindrical with the axial direction being the vertical direction, and the two are coaxially arranged. The upper top head 7 and the lower top head 8 cooperate to fix the rotor to complete the subsequent assembly of the stator and the rotor.

A through hole is provided in the middle of the top plate 3, enabling the lower top head 8 to pass through the top plate 3 and cooperate with the upper top head 7.

[0026] In use, first place the partially assembled motor with the stator installed on the top plate 3 by means of a manipulator, respectively control the upper mounting plate 5 and the lower mounting plate 6 to lift and lower, and then clamp the rotor tooling through the upper top head 7 and the lower top head 8. Then, control the upper mounting plate 5 and the lower mounting plate 6 to move downward, so that the upper top head 7 and the lower top head 8 drive the rotor tooling to move downward into the motor assembly to be installed, and the installation of the generator stator is completed.

[0027] Further, as shown by Figure 1 - Figure 4 In order to make the transportation of the rotor workpiece 2 more stable, the lifting part further includes a first lifting plate 9 and a second lifting plate 10. A first guide rail 11 is provided on the rear side of the first lifting plate 9, and the first lifting plate 9 is slidably connected to the front side wall of the back plate 1 through the first guide rail 11. A second guide rail 12 is provided on the rear side of the second lifting plate 10, and the second lifting plate 10 is slidably connected to the front side wall of the first lifting plate 9 through the second guide rail 12. The lower mounting plate 6 is fixedly connected to the bottom of the first lifting plate 9, and the upper mounting plate 5 is fixedly connected to the top of the second lifting plate 10;

[0028] It should be noted that the number of the first guide rail 11 and the second guide rail 12 is 2 each.

[0029] Further, as shown by Figure 1 - Figure 4 In order to make the height adjustment more accurate, the driving part includes a first lead screw 13 rotatably connected to the rear side of the back plate 1 and a second lead screw 14 rotatably connected to the rear side of the first lifting plate 9. A first lead screw bearing 15 is threadedly connected to the middle of the first lead screw 13. A first connecting block 16 is fixedly connected to the side of the first lead screw bearing 15 close to the rotor workpiece 2, and the first connecting block 16 is fixedly connected to the first lifting plate 9.

A second connecting block 19 is fixedly connected to the front side of the second lead screw bearing 18, and the front side of the second connecting block 19 is fixedly connected to the second lifting plate 10;

[0030] In use, when the first lead screw 13 rotates, the first lifting plate 9 is driven to adjust the height through the first lead screw bearing 15 and the first connecting block 16. When the second lead screw 14 rotates, the second lifting plate 10 is driven to adjust the height relative to the first lifting plate 9 through the second lead screw bearing 18 and the second connecting block 19.

[0031] Further, as shown by Figure 1 - Figure 4As shown, a first assembly block 20 is fixedly connected to the rear side of the back plate 1. The first lead screw 13 is rotatably connected to the back plate 1 through the first assembly block 20. A second assembly block 21 is fixedly connected to the rear side of the first lifting plate 9. The second lead screw 14 is rotatably connected to the first lifting plate 9 through the second assembly block 21.

[0032] Furthermore, as shown by Figure 1 - Figure 4 As shown, for the convenience of the staff's operation, a manual turntable 22 is fixedly connected to the upper sides of both the first lead screw 13 and the second lead screw 14.

[0033] Furthermore, as shown by Figure 1 - Figure 4 As shown, in order to increase the conveying safety of the device, reinforcing ribs are provided on the rear side of the back plate 1.

[0035] When the present utility model is in use, first, the part of the motor assembly with the stator installed is placed on the top plate 3 by the manipulator. The corresponding manual turntable 22 is manually rotated to drive the first lead screw 13 to rotate. The first lead screw bearing 15 drives the first connecting block 16 to move upward along the axial direction of the first lead screw 13, so that the lower top head 8 moves upward to the upper side of the motor assembly. Subsequently, according to the actual situation, the second lead screw 14 is adjusted by the manual turntable 22, so that the second lead screw bearing 18 drives the second connecting block 19 to move upward along the axial direction of the second lead screw 14, so that the upper top head 7 moves away from the lower top head 8. One end of the rotor workpiece 2 grabbed by the manipulator is placed on the upper side of the lower top head 8. Then, the second lead screw 14 is adjusted by the manual turntable 22 to rotate, so that the upper top head 7 moves downward. When the upper top head 7 and the lower top head 8 fix the rotor workpiece 2, the manual turntable 22 is rotated to rotate the first lead screw 13 to drive the first connecting block 16 to move downward, so that the first lifting plate 9 moves downward, and further the entire lifting part drives the rotor workpiece 2 to move downward together. The rotor workpiece 2 descends and is engaged inside the stator of the motor assembly to be installed, realizing the assembly of the stator and rotor. The operation is simple and fast.

[0036] The structure of the present utility model is novel, ingeniously conceived, and simple and convenient to operate.
