Detailed Description
The embodiment provides a shaping device for a stator end of a shielded motor, which is shown in a figure and comprises a stud 1, wherein the stud 1 penetrates through the center of a stator core 2, and external threads are arranged at two ends of the stud 1.
The first shaping tire 9 is arranged outside the first tire core 3 in a matched mode, the second shaping tire 10 is arranged outside the second tire core 4 in a matched mode, the first shaping tire 9 and the second shaping tire 10 are both located in an inner cavity formed by the stator winding 11 and are in contact with the stator core 2, the first shaping tire 9 and the second shaping tire 10 are both integrally processed and are axially trisected, and therefore effective shaping can be conducted according to actual sizes when the shaping tire is used. The outer contours of the first tire core 3 and the second tire core 4 are both conical inclined surface structures, the inner contours of the first shaping tire 9 and the second shaping tire 10 are conical inclined surface structures, when the first driving nut 5 is screwed towards the central direction, the first tire core 3 can move inwards, force is transmitted to the first shaping tire 9 through mutual contact of the conical surface structures, and the first shaping tire 9 can move along the radial direction to realize shaping.
The surfaces of the first core 3 and the second core 4 are provided with three grooves 14 along the axial direction, so that the contact area with the first shaping tire 9 and the second shaping tire 10 can be reduced, and the friction force can be reduced.
The outer end edges of the first shaping tire 9 and the second shaping tire 10 are both fillet structures, the sharp-corner structures are prone to damaging the motor stator winding 11 in the shaping process, and the fillet structures can effectively avoid the risk of damage to the insulation of the stator winding 11 in the shaping process.
The two ends of the outer side of the stator core 2 are respectively detachably connected with a first outer cylinder 12 and a second outer cylinder 13, the first tire core 3 and the first shaping tire 9 are arranged in the first outer cylinder 12, and the second tire core 4 and the second shaping tire 10 are arranged in the second outer cylinder 13. The first outer cylinder 12 and the second outer cylinder 13 are both of two equal-part structures which are detachably connected with each other, and lifting lugs 15 are arranged on the first outer cylinder 12 and the second outer cylinder 13.
The specific working process is as follows: the method comprises the steps of installing a first outer barrel 12 and a second outer barrel 13 at two ends of the outer side of a motor stator core 2 respectively, placing a first shaping tire 9 and a second shaping tire 10 in inner cavities at two ends of a motor stator winding 11 respectively, penetrating a stud 1 through the middle parts of a first tire core 3 and a second tire core 4, installing a first driving nut 5, a first locknut 6, a second driving nut 7 and a second locknut 8 at two ends of the stud 1 respectively, and screwing the first driving nut 5 and the second driving nut 7 at two ends of the stud 1 simultaneously.
