[0043] When in use, firstly, the compacting mechanism 5 is raised, and the telescopic platform 201 is raised. Then, according to the number of demonstration sector pieces 601 surrounding the demonstration rotor piece 6, the outer side tightening mechanism 4 with the same number of slide grooves 402 is selected and placed in the annular groove 102. The positioning spring 105 pushes the fixing block 104 outward to fix the outer side tightening mechanism 4 and make the outer side tightening mechanism 4 coaxial with the central axis 2. The same number of inner side tightening mechanisms 3 are sleeved on the positioning column 205, and the positioning ring 301 is inserted after adjusting the angle from the top of the positioning column 205, so that the hinge points of the extension rods 304 of different inner side tightening mechanisms 3 and the positioning ring 301 are distributed in a circular array in a top view (such as Figure 2 As shown in the figure, it is recommended to insert them in sequence at the same interval angle, and then adjust the telescopic rod 312 and the outer side pressing mechanism 4 so that the middle rod 306 and the screw rod 403 are on a straight line pointing to the center of the round table 101 in a top view, and part of the bottom plate 313 is under the pressing plate 202, and then the telescopic table 201 is retracted, and the pressing plate 202 presses down and presses the bottom plate 313 to fix the telescopic rod 312. Then, the demonstration sector piece 601 can be put between the inner stick 310 and the outer stick 408. After putting it in, turn the adjustment block 404 to adjust the outer side The module 405 is pressed against the position so that the distance between the outer stick 408 and the axis of the positioning column 205 is the same as the maximum radius of the demonstration rotor sheet 6. The outer stick 408 limits the demonstration sector sheet 601 on the outside, and the drive motor 204 is started to rotate the positioning column 205. The positioning column 205 drives the positioning ring 301 to rotate. After the telescopic rod 312 is fixed, the middle rod 306 can only slide in the through hole 314. After the positioning column 205 rotates, the angle between the middle rod 306 and the extension rod 1 304 becomes larger, and the extension rod 1 304 pushes the middle rod 306 outward.

Subsequently, the drive motor 204 is slightly reversed to retract the inner stick 310 slightly, and the demonstration sector piece 601 of the next layer of demonstration rotor piece 6 is continuously placed from top to bottom. After placement is completed, the drive motor 204 is rotated forward to retract the inner stick 310. 310 squeezes the groove 602 outwards. Due to the hinged setting of the second extension rod 308, when the middle rod 306 is pushed outwards, the inner rod 310 will be stretched to both sides after contacting the groove 602, so that the groove 602 of the demonstration sector piece 601 is aligned, and then the demonstration sector piece 601 is continuously laid until the rotor stacking is completed. After the stacking is completed, the external hydraulic equipment presses down the compacting mechanism 5, and the cylinder wall of the pressing cylinder 502 presses down the stacked rotor to compact it, and then the rotor is welded by argon arc welding using external equipment to complete the manufacture of the rotor;

[0044] When processing rotors of different specifications, the same number of inner clamping mechanisms 3 are placed in the above-mentioned manner according to the number of demonstration sector pieces 601 of the single-layer demonstration rotor piece 6, and the outer clamping mechanisms 4 with the same number of slide grooves 402 are selected according to the number of demonstration sector pieces 601, and the adjustment block 404 is rotated according to the outer diameter of the single-layer demonstration rotor piece 6 to adjust the position of the outer rod 408, and the angle between the extension rod 304 and the middle rod 306 is adjusted according to the distance between the inner diameter of the single-layer demonstration rotor piece 6 and the groove 602 closest to the two ends of the single-piece demonstration sector piece 601, so as to adjust the distance from the middle rod 306 to the center of the positioning ring 301, and a pressing cylinder 502 of suitable size is selected for pressing down after stacking is completed. The present invention can flexibly adapt to the production of rotors of various specifications.
