[0038] Exemplarily, the second sleeve 22 can be movably sleeved inside the first sleeve 21 or movably sleeved outside the first sleeve 21 , wherein in this embodiment, the second sleeve 22 is movably sleeved inside the first sleeve 21 .

The selection basis of the cylindrical guide rail 32 and the butterfly slider 31 is heavy load-bearing, the overall load-bearing meets the 5t iron core stacking, and the safety factor is 1.5.

[0043] Specifically, Figure 1 Combination Figure 2 As shown, the lamination workbench is installed with three parallel guide rails 32 according to the planar three-phase yokeless core structure. Each guide rail 32 is equipped with three butterfly-shaped sliders 31, and the three butterfly-shaped sliders 31 are respectively fixed to the first sleeve 21 of the telescopic assembly 2.

The lift 43 is used to ensure smooth lifting or lowering, reliable operation, large load-bearing capacity, synchronization of the four corners, and strong stability. The transmission mechanism 42 includes three T-bevel gear reducers, each of which includes an input shaft and two output shafts. The three T-bevel gear reducers are respectively the first T-bevel gear reducer 421, the second T-bevel gear reducer 422 and the third T-bevel gear reducer 423, wherein the first T-bevel gear reducer 421 is located in the middle of the second load-bearing frame 12, the second T-bevel gear reducer 422 and the third T-bevel gear reducer 423 are located on both sides of the second load-bearing frame 12, the input shaft of the first T-bevel gear reducer 421 is coaxially connected with the drive motor 41 by a coupling, the two output shafts of the first T-bevel gear reducer 421 are coaxially connected with the input shaft of the second T-bevel gear reducer 422 and the input shaft of the third T-bevel gear reducer 423 by a coupling, and the corresponding output shafts of the second T-bevel gear reducer 422 and the third T-bevel gear reducer 423 are transmission-connected with the elevator 43. Optionally, the elevator 43 can be, but is not limited to, a worm gear elevator or a screw elevator.

[0049] Furthermore, a plurality of bottom plates 5 with mounting holes 51 are arranged at circumferential intervals on one side of the second supporting frame 12 away from the first supporting frame 11. At least four bottom plates 5 are installed to the four corners of the second supporting frame 12, and expansion bolts are used to pass through the mounting holes 51 of the bottom plates 5 and firmly connected to the fixed points on the ground to prevent the lamination from being displaced by the crane after the core is assembled. The frame of the base assembly 1 uses 100*100 square tubes, which meet the support requirements and seal the bottom. From a structural point of view, it is prohibited for operators to store debris under the lamination workbench to avoid contact between the limbs and the core.
