After preliminary alignment, the output shaft of the cylinder 10 is extended to drive the drive motor 15 and the calibration mechanism 5 to move synchronously to the inside of the fan shell, and then the calibration mechanism 5 is driven to calibrate and position the horizontal positions of the lower shell 2 and the upper shell 1 by the rotation of the output shaft of the cylinder 10. At this time, the electric clamp 12 and the upper shell 1 are driven by the lifting frame 9 to move so that they contact the alignment mechanism 4. After the alignment is completed, the alignment mechanism 4 is unlocked, and then the output shaft of the electric push rod 11 is extended and retracted to drive the electric clamp 12 to move downward. After the upper shell 1 is placed on the lower shell 2, the electric clamp 12 is released, and then the staff screws the upper shell 1 and the lower shell 2 together to fix them.

The fixed plate 58 is fixedly arranged at the bottom of the drive motor 15, and four limiting channels are fixedly arranged on the side wall of the fixed plate 58 away from the drive motor 15. The four sliding rods 56 are respectively slidably inserted inside the four limiting channels. The four arc-shaped plates 55 are respectively fixed at the ends of the four sliding rods 56.

The four arc-shaped grooves 52 are arranged in a circular array on the turntable 51, and several limiting teeth 53 are fixed on the side wall of the turntable 51. The output shaft of the driving motor 15 rotates to drive the turntable 51, and the rotation of the turntable 51 drives the arc groove 52 to rotate synchronously. The rotation of the arc groove 52 drives the limit column 54 to move, and the movement of the limit column 54 drives the sliding rod 56 to slide inside the limit plate 57. The movement of the sliding rod 56 drives the arc plate 55 to move synchronously, and the inner side walls of the upper shell 1 and the lower shell 2 are restrained and limited by the arc plate 55; it is achieved that the assembly of fan shells of different sizes can be quickly limited, ensuring that the cross section is at the same center of a circle when the upper shell 1 is docked with the lower shell 2, adapting to the docking of fan shells of various sizes, and only one positioning is required without multiple adjustments. The operation is simple, convenient, fast and practical.

First, the lower contact rod 46 is driven to move by the lower shell 2 against the lower contact rod 46, and the lower contact rod 46 moves so that the alignment slot 48 on the lower contact rod 46 is aligned with the long rod. Then, the electric clamp 12 and the upper shell 1 are driven to move by the hanging frame 9 until the upper shell 1 contacts the upper contact rod 45, so that the upper contact rod 45 moves to the corresponding alignment slot 48 and is aligned with the L-shaped long rod 42. At this time, the long rod is unlocked, so that the contact plate 47 releases the limit on the I-plate 41, so that the electric clamp 12 can move downward, and the upper shell 1 is placed on the lower shell 2 for docking; unlocking by the long rod is achieved. In this way, it is possible to determine whether the upper shell 1 and the lower shell 2 are aligned, and avoid the situation where the cross sections are at the same center of a circle but the sides are not aligned.

[0026] Specifically, the width of the two alignment slots 48 is greater than the thickness of the L-shaped long rod 42 .

[0027] Working principle: First, the upper shell 1 is lifted by the electric clamp 12, and then the uninstalled lower fan shell 2 is placed on the conveyor belt 7, and the shell is transported to the bottom of the electric clamp 12 by the conveyor belt 7. After preliminary alignment, the output shaft of the cylinder 10 is extended to drive the drive motor 15 and the calibration mechanism 5 to move synchronously to the inside of the fan shell, and then the output shaft of the drive motor 15 is rotated to drive the turntable 51 to rotate, and the rotation of the turntable 51 drives the arc groove 52 to rotate synchronously, and the rotation of the arc groove 52 drives the limit column 54 to move, and the movement of the limit column 54 drives the sliding rod 56 to slide inside the limit plate 57, and the movement of the sliding rod 56 drives the arc plate 55 to move synchronously, and the inner wall of the upper shell 1 and the lower shell 2 is restrained by the arc plate 55. At this time, the electric clamp 12 and the upper shell 1 are driven to move by the lifting frame 9, and the lower shell 2 is restrained by the lower contact. The rod 46 drives the lower contact rod 46 to move, and the lower contact rod 46 moves so that the alignment slide 48 on the lower contact rod 46 is aligned with the long rod, and then the electric clamp 12 and the upper shell 1 are driven to move by the lifting frame 9 until the upper shell 1 contacts the upper contact rod 45, so that the upper contact rod 45 moves to the corresponding alignment slide 48 and is aligned with the L-shaped long rod 42. At this time, the long rod is unlocked, so that the contact plate 47 releases the limit on the I-plate 41, so that the electric clamp 12 can move downward, and the upper shell 1 is placed on the lower shell 2 for docking. After the alignment is completed, the long rod is unlocked to determine whether the upper shell 1 and the lower shell 2 are aligned, and then the electric clamp 12 is driven downward by the extension and contraction of the output shaft of the electric push rod 11. After the upper shell 1 is placed on the lower shell 2, the electric clamp 12 is released, and then the staff can screw the upper shell 1 and the lower shell 2 together to fix them.
