The two ends of the connecting plate 23 are respectively connected to the inner ring positioning piece 21 and the moving end of the inner ring cylinder 22. The connecting plate 23 drives the inner ring positioning piece 21 to move under the push of the inner ring cylinder 22 to complete the circle splicing operation.

[0059] In another embodiment of the present invention, Figures 1 to 4 As shown, the outer ring positioning device 30 includes an outer ring cylinder 31, a moving block 32 and a fixing part 33. The outer ring cylinder 31 is fixedly installed on the top of the mounting plate 50. The outer ring cylinder 31 is fixedly connected to the assembly plate. The moving block 32 is slidably installed on the top of the mounting plate 50. The fixing part 33 is fixedly installed on the moving block 32, and the fixing part 33 is extended toward the direction of the inner ring positioning part 21. The outer ring cylinder 31 pushes the fixing part 33 to move close to the inner ring positioning part 21 to achieve clamping of the core assembly.

[0060] In another embodiment of the present invention, Figures 1-2 As shown, the circle splicing device 10 includes a base plate 11, a first movable plate 12, a second movable plate 13 and a movable cylinder 14. The first movable plate 12 and the second movable plate 13 are both slidably arranged on the base plate 11. The movable cylinder 14 is fixedly installed on the first movable plate 12, and the movable end of the movable cylinder 14 is connected to the second movable plate 13. Two mounting plates 50 are respectively fixedly installed on the first movable plate 12 and the second movable plate 13. At the same time, a fixed plate is arranged between the first movable plate 12 and the base plate 11. The fixed connection between the first movable plate 12 and the base plate 11 is realized by the fixed plate, ensuring that when the movable cylinder 14 pushes the second movable plate 13 to move, the position of the first movable plate 12 remains unchanged, completing the splicing and opening action of the first movable plate 12 and the second movable plate 13, thereby realizing the completion of the iron core circle splicing operation.

[0061] In another embodiment of the present invention, Figures 1 to 3 As shown, the mounting plate 50 is arranged in a semicircular shape, and the two mounting plates 50 are combined to form a complete circle. The mounting plate 50 is arranged in a semicircular shape, which is more suitable for each outer ring positioning device 30 and inner ring positioning device 20 arranged in a centrally symmetrical arrangement, and saves the material of the mounting plate 50, thereby reducing the cost to a certain extent.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
