[0046] Embodiment 2:

[0047] The difference from the above embodiment is that, please refer to Figure 4 - Figure 6The turning mechanism 5 includes a tool holder body 51, a tool lifting cylinder 52 and a tool limiting frame 55. The tool holder body 51 is fixedly installed on the top of the cutting moving seat 3, the tool lifting cylinder 52 is installed on the transmission mechanism 8, a tool lifting rod 53 is slidably installed inside the tool lifting cylinder 52, and a turning tool 54 is fixedly installed on the top of the tool lifting rod 53. A lifting rail 57 is slidably installed on the inner side wall of the tool holder body 51, and the tool limiting frame 55 is slidably installed on the inner side of the lifting rail 57. A tool sliding groove 56 is opened inside the tool limiting frame 55. An adjusting handle 59 is rotatably installed on the top of the tool holder body 51, and an adjusting screw 58 is fixedly connected to the bottom of the adjusting handle 59;

[0048] The top of the adjusting screw 58 passes through the tool holder body 51 and is fixedly connected to the adjusting handle 59 , and the outside of the adjusting screw 58 is threadedly connected to the inside of the tool limiting frame 55 .

[0049] One end of the tool lifting rod 53 is slidably installed inside the tool lifting cylinder 52, and the other end of the tool lifting rod 53 passes through the tool sliding groove 56 and is fixedly connected to the turning tool 54. The tool limiting frame 55 is divided into three layers horizontally. The upper layer of the tool limiting frame 55 is threadedly connected with the adjusting screw 58, and the lower layer of the tool limiting frame 55 is provided with a tool sliding groove 56. The turning tool 54 contacts the upper surface of the lower layer of the turning mechanism 5.

[0050] When the transmission mechanism 8 is working, it can drive the tool lifting cylinder 52 to move laterally inside the tool holder body 51. When the tool lifting cylinder 52 moves laterally, it can drive the turning tool 54 to move laterally through the tool lifting rod 53 to perform turning operations.

[0051] Both sides of the tool limit frame 55 are slidably installed on the inner wall of the tool holder body 51 through the lifting slide rail 57. When the adjusting handle 59 drives the adjusting screw 58 to rotate, it can drive the tool limit frame 55 to move up and down as a whole inside the tool holder body 51. When the tool limit frame 55 moves up and down, it can drive the turning tool 54 to move synchronously. When the turning tool 54 moves up and down, it can drive the tool lifting rod 53 to slide up and down inside the tool lifting cylinder 52.

[0052] During operation, due to the different structures of motor rotors of different models, the cutting positions of the motor rotors are also different. When the adjusting handle 59 is rotated, the adjusting screw 58 can be driven to rotate. When the adjusting screw 58 is rotated, the tool limit frame 55 can be driven to move up and down as a whole inside the tool holder body 51 along the lifting slide rail 57. When the tool limit frame 55 moves up and down, it can drive the turning tool 54 to move synchronously. When the tool limit frame 55 rises, it can drive the position of the turning tool 54 to rise. When the position of the turning tool 54 rises, the tool lifting rod 53 moves upward inside the tool lifting cylinder 52. When the tool limit frame 55 descends, it can drive the position of the turning tool 54 to descend. When the position of the turning tool 54 descends, the tool lifting rod 53 moves downward inside the tool lifting cylinder 52. The turning tool 54 and the screw mounting block 86 are connected through the tool lifting cylinder 52 and the tool lifting rod 53, so that the transmission mechanism 8 can drive the turning tool 54 to perform turning operations in a cycle when the turning tool 54 is at different heights.

[0053] Embodiment three:

[0054] The difference from the above embodiment is that, please refer to Figure 7 - Figure 8 The rotor fixing mechanism 7 includes a fixed sleeve 71, a telescopic sleeve 72 is fixedly installed inside the fixed sleeve 71, a telescopic spring 73 is fixedly installed inside the telescopic sleeve 72, a telescopic rod 74 is fixedly connected to the top of the telescopic spring 73, a spiral adjustment groove 75 is provided on the outside of the telescopic rod 74, a block connecting plate 76 is slidably installed on the outside of the telescopic rod 74, a rotor block 77 is slidably installed inside the block connecting plate 76, a block spring 78 is fixedly connected inside the rotor block 77, and a block cover plate 79 is fixedly installed inside the fixed sleeve 71;

[0055] The telescopic rod 74 is slidably installed inside the telescopic sleeve 72 , and the bottom of the telescopic rod 74 is connected to the inside of the telescopic sleeve 72 via a telescopic spring 73 .

[0056] The inner side of the block connecting plate 76 is provided with a protrusion which engages with the spiral adjustment groove 75 provided on the outer side of the telescopic rod 74. The diameter of the telescopic rod 74 is larger than the diameter of the central shaft of the motor.

[0057] A plurality of rotor blocks 77 are slidably mounted inside the block connecting plate 76 , the bottoms of the plurality of rotor blocks 77 are inserted into the inside of the block connecting plate 76 , and the bottoms of the plurality of rotor blocks 77 are connected to the block connecting plate 76 via block springs 78 .

When the motor center axis contacts the telescopic rod 74, the telescopic rod 74 can be retracted into the telescopic sleeve 72. When the telescopic rod 74 moves, it can drive the block connecting plate 76 to rotate through the external spiral adjustment groove 75. When the block connecting plate 76 rotates, it can drive the rotor fixing mechanism 7 to rotate as a whole through the rotor block 77.

[0060] When the tailstock 6 of the machine tool approaches the direction of the fixed turntable 4, the rotor block 77 will also approach the direction of the motor rotor. When the position of the rotor block 77 does not match that of the motor rotor, the motor center shaft is inserted into the fixed sleeve 71 from the opening on the block cover plate 79 and contacts the telescopic rod 74. When the tailstock 6 of the machine tool continues to move, the motor center shaft presses the telescopic rod 74 into the telescopic sleeve 72 to compress the telescopic spring 73. The motor rotor will also press the rotor block 77 into the fixed sleeve 71 and compress the block spring 78. When the telescopic rod 74 moves, the block connecting plate 76 can be driven to rotate through the spiral adjustment groove 75 provided on the outside. When the block connecting plate 76 rotates, it can drive the rotor fixing mechanism 7 as a whole through the rotor block 77. Rotation, after the rotor block 77 matches the position of the motor rotor, the block spring 78 rebounds and drives the rotor block 77 to move in the direction of the electronic rotor and fix the position of the motor rotor. When the fixed turntable 4 drives the motor shaft to rotate, the motor rotor and the rotor block 77 can also be engaged to drive the rotor fixing mechanism 7 to rotate as a whole. When the rotor fixing mechanism 7 rotates as a whole, the turning mechanism 5 can be driven to perform turning operations through the transmission mechanism 8. After turning is completed, the machine tool tailstock 6 is away from the fixed turntable 4, and then the motor shaft is pulled out from the inside of the rotor fixing mechanism 7. The telescopic spring 73 rebounds and drives the telescopic rod 74 to move, so that the rotor block 77 can automatically calibrate the position of the rotor when the machine tool tailstock 6 is close to the motor rotor.

[0065] The fixed turntable 4 drives the motor central axis to rotate, which can drive the rotor fixing mechanism 7 to rotate through the motor rotor. When the rotor fixing mechanism 7 rotates, it can drive the roller connecting rod 84 to rotate through the upper roller 81 and the roller belt 83. When the roller connecting rod 84 rotates, it can synchronously drive the reciprocating screw 85 to rotate. When the reciprocating screw 85 rotates, it can drive the turning mechanism 5 to perform a cyclic turning operation through the screw mounting block 86.

[0066] When the rotor fixing mechanism 7 rotates, the upper roller 81 can be driven to rotate. When the upper roller 81 rotates, the lower roller 82 and the roller connecting rod 84 can be driven to rotate through the roller belt 83.
