[0015] The motor rotor winding tool is composed of a positioning mechanism and a pressing mechanism. When fixing the winding skeleton, the motor rotor winding tool is first installed on the rotor winding equipment, that is, the positioning mechanism is installed on the driving shaft of the equipment through the first installation shaft segment, and the pressing mechanism is rotatably installed on the equipment through the first installation shaft segment. Then the winding skeleton is sleeved on the expansion sleeve, and then the pressing mechanism is driven by the winding equipment to move towards the positioning mechanism. During this process, when the limiting shaft segment of the pressing mechanism contacts the expansion sleeve, the limiting shaft segment starts to drive the expansion sleeve to slide on the conical shaft segment. Under the drive of the conical shaft segment, the outer diameter of the expansion sleeve will continuously increase until the outer circle of the expansion sleeve well fits the inner hole wall of the winding skeleton, that is, the radial fixation of the winding skeleton is formed.

[0024] The motor rotor winding tool of the present application is composed of a positioning mechanism and a compression mechanism. The limiting shaft segment drives the expansion sleeve to slide on the tapered shaft segment, so that the outer circle of the expansion sleeve is well fitted with the inner hole wall of the winding framework, that is, the radial fixation of the winding framework is formed. And the winding framework is finally pressed between the positioning sleeve and the flange shaft segment of the first rotating shaft, forming the axial fixation of the winding framework. And the pressure applied to the positioning sleeve by the compressed spring after compression makes the positioning sleeve tightly press against the winding framework, avoiding the axial displacement of the winding framework. The radial and axial of the winding framework are well fixed, improving the assembly quality of the winding framework, avoiding the poor winding caused by poor limiting of the winding framework, and improving the product quality.

[0033] In the embodiment, at least two compression springs 4 are arranged between the fixing part 5 and the positioning sleeve 3, and the two ends of each compression spring 4 abut against the fixing part 5 and the positioning sleeve 3 respectively. The second mounting shaft section 602 is used to be connected with the rotor winding equipment to drive the compression mechanism to move towards the positioning mechanism, and the winding framework 9 sleeved on the expansion sleeve 2 is fixed between the positioning sleeve 3 and the flange shaft section 103 of the first rotating shaft 1, and the shaft end face of the limiting shaft section 601 abuts against the shaft end face of the expansion sleeve 2 to form the axial fixation of the expansion sleeve 2.
