[0032] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] See also Figure 1-Figure 5 A stator inner winding machine clamping fixture according to a preferred embodiment of the utility model comprises a stator seat 2, the stator seat 2 comprises a stator mounting seat 21 and a clamping platform 22, the clamping platform 22 is convexly arranged on the stator mounting seat 21, a mounting cavity 212 for placing the stator 1 is arranged at the lower part of the stator mounting seat 21, and a plurality of through holes 211 connected to the mounting cavity 212 are also arranged on the side of the stator mounting seat 21. The stator seat 2 is in a circular shape as a whole, and is formed by cutting three planes arranged in an array on it.

[0034] The rotating seat 3 is mounted on the upper part of the clamping platform 22 of the stator seat 2 . The clamping platform 22 is cylindrical and protrudes from the mounting seat 21 .

[0035] A fixed block 6 is installed at the bottom of the rotating seat 3, and a pressure arm 5 is installed in the fixed block 6 through a first pin shaft 7. One end of a spring 4 is connected to the upper part of the pressure arm, and the other end of the spring 4 is snap-fitted into the upper outer wall of the rotating seat 3. The bottom of the pressure arm 5 is rotatably connected to one end of a clamping block 9 through a second pin shaft 8, and the main body of the clamping block 9 is slidably set into the through hole 211.

[0036] There are three through holes 211 arranged in an array on the outer wall of the stator mounting seat 21 , and the through holes 211 are square through holes.

[0037] A circular groove is arranged on the upper part of the rotating seat 3, and one end of the spring 4 is arranged in the circular groove. The specific fixing can be carried out in various ways, such as welding fixing, adhesive fixing, or clamping fixing.

[0038] The end of the fixing block 6 away from the second pin 8 is arc-shaped in order to fit the circular outer surface of the stator.

[0039] The working principle of the utility model is as follows:

[0040] The utility model has three sets of pressing arms arranged on the rotating seat, the pressing arms are pressed by springs, and the pressing blocks are connected to the lower parts of the pressing arms through pin connecting rods, so that the pressing blocks can press the internal stator to fix the stator.

[0041] The main purpose of this structure is to meet the needs of passing wires on the upper end of the winding stator. When the space is relatively small, this clamping method is used to fix the stator without occupying the wire passing space on the upper part of the stator.
