[0027] In order to facilitate the full fixation of the rotor, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, it includes a base 1, on which is provided a base 13 for placing the rotor. There are four bases 13, and they are arranged symmetrically in pairs. The opposite sides of each two symmetrical bases 13 are provided with inclined portions 6, and a gap is reserved between the two symmetrical bases 13, forming a V-shaped placement groove between the inclined portions 6, which facilitates subsequent operation of the rotor. A pressure block seat 2 for fixing the rotor to the base 13 is provided vertically above the base 13. The pressure block seat 2 is provided with a first driving component for driving the pressure block seat 2 to rise and fall in the absence of power. A rod is inserted into the pressure handle 5, and the rod is rotated to make the pressure block seat 2 descend, and the pressure block 14 can also be abutted against the rotor for fixing. A connecting rod is provided on the outside of the pressure block seat 2. The connecting rod is connected to a housing 17 at one end away from the pressure block seat 2 for abutting and fixing one end of the rotor. A second driving component is provided in the housing 17 for driving the pressure block seat 2 to rise and fall when the power is on. The second motor 23 is started, and the power output end of the second motor 23 drives the first gear 22 to rotate, driving the second gear 24 to rotate, causing the second screw 18 to rotate, causing the first bearing sleeve 25 to descend on the second screw 18, driving the telescopic rod 12 to descend, thereby lowering the pressure block seat 2 and allowing the pressure block 14 to abut against the rotor. A third driving component is also provided in the base 1 for changing the axial position of the housing 17 on the base 1 according to the length of the rotor. The first screw 10 is driven to rotate by the power output end of the first motor 7, causing the second bearing sleeve 26 to move on the first screw 10, driving the movement of the housing 17, and causing the housing 17 to abut against one end of the rotor.

[0028] In order to improve the stability when wearing the rotor, refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, a support frame 3 is provided on the upper surface of the base 1, and the first driving assembly includes a clamping bolt 4 mounted on the support frame 3. The clamping bolt 4 passes through the support frame 3, and a threaded hole is provided on the support frame 3 to match the clamping bolt 4. A pressure handle 5 for rotating the clamping bolt 4 is connected to the upper surface of the clamping bolt 4, and the lower surface of the clamping bolt 4 is connected to the pressure block seat 2. A second slide groove 16 is provided on both sides of the support frame 3, and a first connecting rod 15 slides in the second slide groove 16. The end of the first connecting rod 15 away from the second slide groove 16 is connected to the pressure block seat 2. The first connecting rod 15 slides axially in the second slide groove 16, so that the pressure block seat 2 can be rotationally limited, thereby ensuring that the pressure block seat 2 can be raised or lowered. The second drive assembly includes a second screw 18 installed in the housing 17, and a first bearing sleeve 25 is provided on the second screw 18. The first bearing sleeve 25 is connected to the telescopic rod 12. A second motor 23 is also provided in the housing 17. The second motor 23 is existing technology and will not be described here. The power output end of the second motor 23 is connected to the first gear 22, and the outer side of the first gear 22 is meshed with the second gear 24. The second gear 24 is installed on the rotating shaft, the upper surface of the rotating shaft is connected to the second screw 18, and the lower surface of the rotating shaft is installed on the lower surface of the shell 17. Third slide grooves 21 are opened on both sides of the shell 17, and a second connecting rod 19 slides in the third slide groove 21. The second connecting rod 19 is connected to the first bearing sleeve 25 at one end away from the third slide groove 21. The second connecting rod 19 slides in the third slide groove 21 to limit the rotation of the first bearing sleeve 25 so that the first bearing sleeve 25 can move on the second screw 18 to realize the displacement of the shell 17. When the shell 17 approaches the pressure block seat 2, the telescopic rod 12 will be squeezed and the telescopic rod 12 will contract. When the shell 17 is away from the pressure block seat 2, the telescopic rod 12 is stretched.

[0029] Furthermore, the third drive assembly includes a strip groove 8 formed on the upper surface of the base 1. A first screw 10 is provided in the strip groove 8. A second bearing sleeve 26 is provided on the outer side of the first screw 10. Two third connecting rods 20 are symmetrically provided on the outer side of the second bearing sleeve 26.

The upper surface of the second bearing sleeve 26 is connected to the lower surface of the housing 17. When the first screw 10 rotates, the third connecting rod 20 slides in the first sliding groove 9, limiting the rotation of the second bearing sleeve 26 so that the second bearing sleeve 26 can move on the first screw 10. The first screw 10 extends through the strip groove 8 to the outside of the base 1 and is connected to the first motor 7. The upper surface of the pressure block seat 2 is provided with a reinforcing rib 11. The reinforcing rib 11 increases the self-stress resistance of the pressure block seat 2 and improves the stability after the rotor is fixed. A pressing block 14 for pressing the rotor is provided on the lower surface of the pressing block seat 2. The contact surface between the pressing block 14 and the rotor is arc-shaped, so as to better fit the rotor and fix the rotor.

[0031] In step A, the rotor is first placed on the inclined portion 6 between the bases 13. The first motor 7 is started according to the axial length of the rotor. The power output end of the first motor 7 drives the first screw 10 to rotate, causing the second bearing sleeve 26 to rotate accordingly. As the third connecting rod 20 slides in the first chute 9, the second bearing sleeve 26 is rotationally limited, allowing the second bearing sleeve 26 to move on the first screw 10, driving the movement of the housing 17, so that the housing 17 abuts against one end of the rotor.

[0032] Step B, when there is power, start the second motor 23, the power output end of the second motor 23 drives the first gear 22 to rotate, and the first gear 22 is engaged with the second gear 24, driving the second gear 24 to rotate, so that the second screw 18 rotates, driving the first bearing sleeve 25 to rotate, as the second connecting rod 19 slides in the third slide groove 21, the first bearing sleeve 25 is rotationally limited, so that the first bearing sleeve 25 descends on the second screw 18, driving the telescopic rod 12 to descend, thereby lowering the pressure block seat 2, allowing the pressure block 14 to abut against the rotor;

[0033] Step C: When there is no power, insert a rod into the pressure handle 5 and rotate the rod to drive the clamping bolt 4 to rotate. As the first connecting rod 15 slides in the second slide groove 16, the pressure block seat 2 is rotationally limited, causing the pressure block seat 2 to descend. The pressure block 14 can also be fixed against the rotor;

[0034] Step D: Finally, after fixing the rotor between the pressing block 14 and the base 13, the flange on the main shaft is docked and fixed with the annular flange bracket in the middle of the inner cavity of the rotor yoke cylinder to complete the rotor insertion.
