Example Embodiment
[0036] Example one:
[0037] The thermal sleeve positioning tooling of the stator core and the casing includes an upper base 1, a lower base 2, a guide post, a support panel 4, a lifting drive source 5, a mounting seat 6, a positioning boss 61, and an inner support slider 7 , Telescopic guide rod 8, spring 10, positioning seat 11, limiting structure and positioning structure.
[0038] Specifically, such as figure 1 As shown, the number of uprights 3 in this embodiment is two, each upright 3 has external threads at both ends, and the upper end of the upright 3 passes through the fixing sleeve 22 on the upper base 1 and is fixed to the upper base 1 by a nut 24 , The lower end of the column 3 passes through the fixing sleeve 23 on the lower base 2 and is fixed to the lower base 2 by a nut 24. A flange linear bearing 25 is fixed on the support panel 4, and the column 3 passes through the corresponding flange straight line. Bearing 25 on. The upper base 1, the lower base 2 and the col...
Example Embodiment
[0048] Embodiment two:
[0049] The technical solution in this embodiment is basically the same as that in the first embodiment. The difference is that in this embodiment, the limiting structure includes a plurality of screw holes fixed on the mounting base 6 and matching the screw holes of the casing 31 Limit pin.
Example Embodiment
[0050] Embodiment three:
[0051] The technical solutions in this embodiment are basically the same as those in the first and second embodiments. The difference is that in this embodiment, the positioning structure includes a convex body with elasticity, and the center of the upper end of the positioning seat 11 is higher than the positioning The convex portion 111 of the seat 11 has an annular receiving groove 112 on the outer periphery of the convex portion 111, and the convex body is fixed on the outer surface of the convex portion 111. When the stator core 32 is placed in the accommodating groove 112, by rotating the stator core 32 in a circumferential direction, the convex body is elastically deformed and locked into the stator slot 321, thereby realizing the positioning of the stator core 32.
