[0042] See also Figure 1 , Figure 2 and Figure 4 , the rotor winding shaping mechanism provided in the embodiment of the present application is now described. The rotor winding shaping mechanism is used to wind the rotor core 10, including a frame 1, a rotating assembly 2, a shaping assembly 3 and a plug assembly 4. Optionally, the rotor core 10 can be mounted on the frame 1 and can be rotated on the frame 1, so that the winding mechanism can be used for winding. The rotating assembly 2 is mounted on the frame 1, and the rotating assembly 2 can be connected with the rotor core 10, so that the rotor core 10 can be driven to rotate on the frame 1. The shaping assembly 3 includes two shaping blocks 31 and two shaping driving members 32, the two shaping driving members 32 are respectively mounted on the frame 1, and the two shaping driving members 32 are respectively connected to the two shaping blocks 31. The two shaping assemblies 3 can be respectively arranged at the two ends of the rotor core 10, and the two shaping driving members 32 can drive the two groups of shaping blocks 31 to approach or move away from each other along the X-axis direction, so that the winding at the end of the rotor core 10 can be shaped. See also Figure 5, the insert assembly 4 includes an insert body 41 and an insert driver 42, the insert driver 42 is mounted on the frame 1 and connected to the insert body 41; the insert driver 42 can drive the insert body 41 to reciprocate in and out of the slot of the rotor core 10, so that the winding can be pressed into the slot. Among them, each shaping driver 32 and the insert driver 42 can be a cylinder. In this structure, the two shaping blocks 31 are driven to move away from or close to each other by the two shaping drivers 32 respectively. When the two shaping blocks 31 are close to each other, the two shaping blocks 31 can shape the winding at the end of the rotor core 10, squeeze the winding toward the middle of the rotor core 10, and reduce the bulging of the winding at the middle position of the rotor core 10. The insert driver 42 can drive the insert body 41 to reciprocate in and out of the slot of the rotor core 10, and the bulging winding at the slot position of the rotor core 10 can be shaped. In this way, by shaping the windings at the ends and the middle of the rotor core 10 respectively, bulging defects of the windings of the rotor core 10 can be effectively avoided, thereby improving the winding quality of the rotor core 10.

[0043] In one embodiment, see Figure 4 As a specific implementation of the rotor winding shaping mechanism provided in the embodiment of the present application, each group of shaping blocks 31 includes a shaping plate 311 connected to the shaping drive member 32 and two shaping seats 312 installed on the shaping plate 311 at intervals. Specifically, the two shaping plates 311 are arranged at intervals, and the four shaping seats 312 on the two groups of shaping blocks 31 are arranged opposite to each other in pairs. The two shaping seats 312 on each shaping plate 311 can adjust the installation position, so that the distance between the two shaping seats 312 can be adjusted to adapt to rotor cores 10 of different sizes. In this structure, the shaping operation is performed through four shaping seats 312, and the four shaping seats 312 are divided into two groups. The two groups of shaping seats 312 can shape the windings at both ends of the rotor core 10 respectively, so that the shaping efficiency of the ends of the rotor core 10 can be improved.

[0044] In one embodiment, see Figure 4 As a specific implementation of the rotor winding shaping mechanism provided in the embodiment of the present application, each shaping seat 312 is provided with an arc-shaped groove portion 3121. Specifically, each shaping seat 312 is provided with an arc-shaped groove portion 3121 on the side facing the rotor core 10; each arc-shaped groove portion 3121 is roughly in a semicircular structure. This structure can be adapted to the rotor core 10 in a cylindrical configuration through the arc-shaped groove portion 3121, so that the shaping efficiency can be improved; at the same time, it can also achieve the avoidance of the rotating shaft 20 on the rotor core 10.

[0045] In one embodiment, see Figure 3 and Figure 5As a specific implementation of the rotor winding shaping mechanism provided in the embodiment of the present application, the insert assembly 4 includes a first stopper 43 mounted on the insert driving member 42; and a second stopper 11 is mounted on the frame 1. This structure can limit the maximum moving stroke of the insert body 41 through the cooperation and abutment between the first stopper 43 and the second stopper 11, thereby preventing the insert body 41 from damaging the winding due to exceeding the stroke.

[0046] In one embodiment, see Figure 2 As a specific implementation of the rotor winding shaping mechanism provided in the embodiment of the present application, the number of the inserting blade assemblies 4 is two, and the two inserting blade assemblies 4 are respectively arranged at both ends of the rotor core 10. Specifically, the two inserting blade assemblies 4 are symmetrically distributed; each inserting blade assembly 4 can be respectively arranged between two corresponding shaping seats 312. In this structure, the shaping efficiency of the notch of the rotor core 10 can be improved through the two inserting blade assemblies 4.

Among them, the rotating driving member 24 can be a cylinder. In this structure, when the rotating driving member 24 drives the sliding seat 22 to slide on the mounting seat 21, the sliding seat 22 can also drive the hook 23 to move, and the hook 23 can drive the rotor core 10 engaged therewith to rotate during the movement. When the unhooking position is reached, the hook 23 is unhooked from the rotor core 10, and the rotor core 10 rotates into place. When the rotating driving member 24 drives the sliding seat 22 to move in the reverse direction and reset, the hook 23 stops when it engages with the next notch of the rotor core 10. Repeating the operation can drive the rotor core 10 to rotate, and then cooperate with the shaping assembly 3 and the insert assembly 4 to achieve the shaping of the winding.

[0048] In some embodiments, the rotating assembly 2 may also be a plug plate, a lifting cylinder for driving the plug plate to reciprocate in and out of the slot of the rotor core 10, and a transverse cylinder for driving the plug plate to move laterally; the plug plate is connected to the lifting cylinder, the lifting cylinder is connected to the transverse cylinder, and the transverse cylinder can be installed on the frame 1. In this structure, the lifting cylinder can drive the plug plate to extend into the slot, and the transverse cylinder can drive the plug plate to move laterally, thereby driving the rotor core 10 to rotate. In some other embodiments, the rotating assembly 2 may also be a motor installed on the frame 1, and the motor is directly connected to the rotating shaft 20, and can also drive the rotation of the rotor core 10. Of course, in other embodiments, the structure of the rotating assembly 2 can also be adjusted according to actual needs, and this is not the only limitation.

[0050] In one embodiment, see Figure 6 The mounting seat 21 is also provided with a positioning groove 212 for the sliding seat 22 to extend into, and the length direction of the positioning groove 212 is the same as the sliding direction of the sliding seat 22. This structure can guide the sliding seat 22 through the positioning groove 212, thereby improving the reliability of the sliding seat 22 sliding back and forth on the mounting seat 21.

In this structure, the rotor core 10 to be wound can be transferred by the frame and the transmission line, and the rotor core 10 on the frame can be lifted to the shaping position by the lifting drive unit 5, so that automatic loading can be achieved. After the rotor core 10 is shaped, it can also be transferred to the frame again by the lifting drive unit 5 and removed by the transmission line.
