Description
Technical Field
The utility model relates to a motor manufacturing technology field, in particular to workable stator core is with card line insulating ring.
Background
A plurality of convex teeth are arranged on the stator iron core and used for winding coils, and the rotor moves through electromagnetic induction. The number of the coils wound on the stator core is generally more than one, a complex winding structure can be formed, and the coils cannot be loosened after the winding is finished, so that the coils are often fixed by binding wires on the periphery of the coils. However, the operation of the specific binding wire is complicated, the positions are many, much manpower is needed, and the production efficiency is delayed.
Therefore, the insulating ring capable of clamping the wire is designed, and the structure is that an outward turning structure is arranged on the plate surface of the insulating ring, so that the wire end is clamped in the outward turning structure after being bound. However, the insulating plate is inconvenient to manufacture because the insulating ring is manufactured in an injection molding mode, and the outward turning structure causes the material removal to be troublesome and careless, and the outward turning edge is broken when the material is removed, so that the product is scrapped because the wire clamping effect cannot be achieved.
Therefore, it is necessary to develop a new structure to solve the above problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an workable stator core is with card line insulating ring can let the card line part simple structure of shaping insulating ring.
The utility model discloses a following technical scheme realizes above-mentioned purpose: the utility model provides an workable stator core is with card line insulating ring, includes annular board body, the periphery equipartition of board body has a plurality of dogtooths, the inner edge of board body is provided with the arc limit up the arch, card line portion is stretched out toward the centre of a circle direction of board body to the upper end on arc limit, the board body is just being provided with the technology perforation that the structure corresponds on the position of card line portion.
Specifically, the arc edges all use the axis of the plate body as the center of a circle and are divided into multiple sections which are independent from each other, and each arc edge is provided with at least one line clamping part.
Specifically, an expansion part used for embedding the knurled nut is further arranged on the arc edge.
The utility model discloses technical scheme's beneficial effect is:
the insulating ring not only has the wire clamping function, but also can enable the wire clamping part to be produced by a simple vertical demolding mold, simplifies the manufacturing process and lightens the weight of the insulating ring.

Detailed Description
The present invention will be described in further detail with reference to specific examples.
Example (b):
as shown in fig. 1 to 3, the utility model discloses an workable stator core is with card line insulating ring, including annular board body 1, the periphery equipartition of board body 1 has a plurality of dogtooths 11, and the inner edge of board body 1 is the arch up and is provided with arc limit 12, and card line portion 13 is stretched out toward the centre of a circle direction of board body 1 to the upper end of arc limit 12, and board body 1 is provided with the technology perforation 14 that the structure corresponds on just to the position of card line portion 13. In actual use, the insulating ring is fixed on the side of the stator core 2, and the arc edge 12 is outward, at this time, the convex teeth 11 correspond to the branch parts 21 of the stator core 2 one by one, and the coil is wound on the outer sides of the convex teeth 11 and the branch parts 21. After the coil is wound, the wire end only needs to be bundled in a small range and then is directly clamped in the wire clamping part 13, so that the trouble of manually binding the wire on the whole stator core is avoided. Because the process through hole 14 is formed in the plate body 1, the clamping wire part 13 can be formed only by partially protruding the die cavity in the process through hole 14, after the material is solidified, the material can be directly removed from the vertical direction of the plate surface by removing the material, and the insulation ring can be produced by using a common vertical demolding die, so that the manufacturing process is simplified, and the weight of the insulation ring is reduced.
As shown in fig. 1 and 2, the arc edge 12 is centered on the axis of the plate body 1 and divided into multiple independent segments, and each segment of the arc edge 12 has at least one clipping line portion 13. In practical application, the coil has more than one leading-out end, and the winding position is outside the arc-shaped side 12, so the arc-shaped sides 12 are mutually disconnected, and the leading-out end of the coil can be clamped below the wire clamping part 13 nearby.
As shown in fig. 1 and 2, the arc edge 12 is further provided with an expansion portion 15 for embedding the knurled nut. In some stator cores, the insulating ring is used for fixing other parts through screws, and the insulating ring is usually subjected to injection molding, so that knurled nuts can be embedded in the insulating ring, and the requirements on strength and precision are met.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
