Detailed Description
Fig. 1 and fig. 2 schematically show a motor stator core pre-pressing tool according to an embodiment of the present invention. As shown in fig. 1 and fig. 2, the motor stator core prepressing tool includes a support base plate 4, a prepressing plate 6 and a double-headed screw 1.
The support base plate 4 is in the shape of a circular arc flat plate. One pair of corresponding two sides are arc sides with the same radian, wherein the length of one arc side is greater than that of the other arc side, and the other pair of corresponding two sides are symmetrically arranged straight sides. The surface of the support chassis 4 is provided with bosses 41. One arc edge of the boss 41 coincides with the shorter arc edge of the support base plate 4, and the other arc edge of the boss 41 does not coincide with the longer arc edge of the support base plate 4 and has the same radian. The motor stator iron core 5 is formed by overlapping a plurality of layers of punching sheets. The working area of the support base 4 is larger than the end area of the core. A first plurality of second threaded holes are formed in the supporting base plate 4. And a second threaded hole on the supporting bottom plate 4 corresponds to a groove of the punching sheet. The second screw hole is equipped with three. The pre-press plate 6 is pressed against the stack. And a second threaded hole corresponding to the first threaded hole is formed in the prepressing plate 6. And a second threaded hole on the prepressing plate 6 corresponds to a groove of the punching sheet. The double-end screw 1 sequentially penetrates through a first threaded hole of the prepressing plate 6, the multilayer laminated core 5 and a second threaded hole of the supporting base plate 4. The double-ended screw 1 is screwed in a first fastening nut 8 at one end of the prepressing plate 6. The double-headed screw 1 is screwed into the second fastening nut 2 at the other end of the support base plate 4. The double-end screw 1 is of multiple length specifications, and is suitable for electronic iron core pre-pressing tools of different specifications. A first gasket 7 is arranged between the first fastening nut 8 and the prepressing plate 6, and a second gasket 3 is arranged between the second fastening nut 2 and the supporting bottom plate 4.
Firstly, a supporting bottom plate is placed before lamination, lamination operation is carried out on the boss surface of the supporting bottom plate 4, the supporting bottom plate is folded to the height needing prepressing, a prepressing plate 6 is hoisted, a double-head screw 1 penetrates into corresponding holes on the upper portion and the lower portion of the supporting bottom plate 4 and the prepressing plate 6, the supporting bottom plate 4 and the prepressing plate 6 are tightened through a fastening nut, and therefore the effect of prepressing the iron core 5 is achieved.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
