The two second arc-shaped clamping plates 7 are respectively welded to the corresponding second movable plate members 6. The two first movable plate members 3 respectively slide along the corresponding surface of the workbench 1. The two first arc-shaped clamping plates 4 are respectively welded to the corresponding first movable plate members 3. The two first arc-shaped clamping plates 4 respectively clamp the outside of the rotor core segments 16 from the outside, and the two second arc-shaped clamping plates 7 respectively clamp the inside of the rotor core segments 16 from the inside.
[0021] The first bidirectional lead screw 10 rotates through the workbench 1. The two first threaded sleeves 2 are symmetrically distributed on the first bidirectional lead screw 10. The inner surfaces of the two first threaded sleeves 2 are respectively threadedly connected to the surface of the corresponding first bidirectional lead screw 10.
[0022] The second bidirectional lead screw 15 rotates through the workbench 1. The two second threaded sleeves 5 are symmetrically distributed on the second bidirectional lead screw 15. The inner surfaces of the two second threaded sleeves 5 are respectively distributed and threadedly connected to the surface of the corresponding second bidirectional lead screw 15.
[0023] Two movable plate members 3 are respectively fixedly sleeved on corresponding threaded sleeves 2, and two movable plate members 6 are respectively fixedly sleeved on corresponding threaded sleeves 5.
[0024] A first motor 8 is installed on the left side of the workbench 1. The output shaft of the first motor 8 is fixedly sleeved with a first motor gear 9. The surface of the first bidirectional lead screw 10 is fixedly sleeved with a first gear 11, and the surface of the first gear 11 meshes with the surface of the first motor gear 9.
[0025] A second motor 12 is installed on the left side of the workbench 1. The output shaft of the second motor 12 is fixedly sleeved with a second motor gear 13. The surface of the second bidirectional lead screw 15 is fixedly sleeved with a second gear 14, and the surface of the second gear 14 meshes with the surface of the second motor gear 13.
[0026] When it is necessary to clamp the rotor core slices;
[0027] First, start the second motor 12. The start of the second motor 12 drives the second motor gear 13 to rotate. The rotation of the second motor gear 13 drives the second gear 14 to rotate. The rotation of the second gear 14 drives the second bidirectional lead screw 15 to rotate. The rotation of the second bidirectional lead screw 15 drives the two threaded sleeves 5 to move away from each other. The movement away from each other of the two threaded sleeves 5 drives the corresponding movable plate members 6 to move away from each other. The movement away from each other of the two movable plate members 6 drives the corresponding arc-shaped clamping plates 7 to move away from each other to support the inside of the rotor core slice 16.
[0028] Secondly, start the first motor 8. The start of the first motor 8 drives the first motor gear 9 to rotate. The rotation of the first motor gear 9 drives the first gear 11 to rotate. The rotation of the first gear 11 drives the first bidirectional lead screw 10 to rotate. The rotation of the first bidirectional lead screw 10 drives the two threaded sleeves 2 to move relatively. The relative movement of the two threaded sleeves 2 respectively drives the corresponding movable plate members 3 to move relatively. The relative movement of the two movable plate members 3 drives the corresponding arc-shaped clamping plates 4 to move relatively to clamp the outside of the rotor core slice 16.
[0029] By providing the two arc-shaped clamping plates 4 and the two arc-shaped clamping plates 7 in the clamping assembly, wherein the two arc-shaped clamping plates 4 clamp the rotor core slice 16 from the outside. At the same time, the two arc-shaped clamping plates 7 support and clamp the rotor core slice 16 from the inside of the rotor core slice 16. Compared with the general method of clamping from the two sides outside the rotor core slice 16, the method of clamping both inside and outside at the same time is more stable and reliable.
[0030] By setting both the two arc-shaped clamping plates 1-4 and the two arc-shaped clamping plates 2-7 to perform relative movements, where the two arc-shaped clamping plates 1-4 perform relative movements with the same process, and the two arc-shaped clamping plates 2-7 perform opposite movements with the same process, so that the positions at the centers of the rotor core segments 16 after each clamping are kept consistent, thus facilitating subsequent processing of the rotor core segments 16.
[0031] Working principle:
[0032] When it is necessary to clamp the rotor core segments;
[0033] First, start the second motor 12. The start of the second motor 12 drives the second motor gear 13 to rotate. The rotation of the second motor gear 13 drives the second gear 14 to rotate. The rotation of the second gear 14 drives the two-way lead screw 2-15 to rotate. The rotation of the two-way lead screw 2-15 drives the two threaded sleeves 2-5 to move away from each other. The opposite movement of the two threaded sleeves 2-5 drives the corresponding movable plate members 2-6 to move away from each other. The opposite movement of the two movable plate members 2-6 drives the corresponding arc-shaped clamping plates 2-7 to move away from each other to support the inside of the rotor core segment 16.
[0034] Secondly, start the first motor 8. The start of the first motor 8 drives the first motor gear 9 to rotate. The rotation of the first motor gear 9 drives the first gear 11 to rotate. The rotation of the first gear 11 drives the two-way lead screw 1-10 to rotate. The rotation of the two-way lead screw 1-10 drives the two threaded sleeves 1-2 to perform relative movements. The relative movements of the two threaded sleeves 1-2 respectively drive the corresponding movable plate members 1-3 to perform relative movements. The relative movements of the two movable plate members 1-3 drive the corresponding arc-shaped clamping plates 1-4 to perform relative movements to clamp the outside of the rotor core segment 16.
[0035] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the purpose of the present invention.
