As shown in fig. 1 to 10, the winding pressing tool 400 includes a force-receiving portion 410, a plurality of extending portions 420 and a plurality of pressing portions 430, the plurality of extending portions 420 are annularly arranged and connected to the force-receiving portion 410, one side of the extending portion 420 away from the force-receiving portion 410 is connected to at least one pressing portion 430, and the pressing portion 430 is used for being inserted between two adjacent tooth portions 210 on the iron core 200 and abutting against the winding 300 sleeved on the tooth portions 210, so that a preformed concave portion 510 opposite to the pressing portion 430 is formed on the potting adhesive 500 fixing the winding 300.

The side of the stress portion 410 that deviates from the extension portion 420 can be the action surface of the external force, and when the external force acts on the action surface, the winding 300 can be compressed, specifically, the compression portion 430 is inserted between two adjacent tooth portions 210 and abuts against and is sleeved on the winding 300 on the tooth portion 210, so that the winding 300 can be subsequently fixed by pouring glue, after the pouring glue 500 is cured, the winding compression tool 400 is taken down, and then the cured pouring glue 500 is formed with a reserved concave portion 510.

The external force may be mechanical equipment or a weight, and the external force may be uniformly dispersed on each of the extensions 420, so that each of the windings 300 may be uniformly stressed, and displacement and deviation of the windings 300 during glue filling are prevented, thereby fixing the windings 300 at a desired position.

As shown in fig. 1, the force receiving portion 410 is annular, a plurality of extending portions 420 extend along the axial direction of the force receiving portion 410, and the length of the force receiving portion 410 in the axial direction is smaller than the length of the extending portions 420 in the axial direction, in one example, the length of the extending portions 420 in the axial direction is two times or more than the length of the force receiving portion 410 in the axial direction. Of course, the force-receiving portion 410 may also be circular or square, and the like, without limitation.

The plurality of extensions 420 are disposed at equal intervals along the circumferential direction of the force-receiving portion 410, so that the plurality of extensions 420 are annularly arranged, wherein the distance between two adjacent extensions 420 is the same as the distance between two adjacent teeth 210, referring to fig. 8, when the winding pressing tool 400 presses the winding 300, the pressing portion 430 and the teeth 210 are disposed in a staggered manner, and each pressing portion 430 can press the winding 300 located between two adjacent teeth 210.

As shown in fig. 1 and 8, the cross section of the extension part 420 is rectangular, and the extension part 420 is not inserted between two adjacent teeth 210, so the shape of the extension part 420 is not limited, and may be a sector shape. The length of the extension portion 420 in the radial direction of the force-receiving portion 410 may be the same as the width between the inner and outer sidewalls of the force-receiving portion 410, and may be flush with each other.

The length of the pressing portion 430 in the circumferential direction of the force receiving portion 410 is smaller than or equal to the distance between two adjacent teeth 210, so that the pressing portion 430 can be inserted between two adjacent teeth 210. It can be seen that each of the pressing portions 430 can simultaneously abut on the windings 300 outside two of the teeth portions 210, refer to fig. 8.

Referring to fig. 1, the pressing portion 430 and the extension portion 420 have the same length in the circumferential direction of the force receiving portion 410. And the length of the pressing portion 430 in the radial direction of the force receiving portion 410 is smaller than the length of the extension portion 420 in the radial direction of the force receiving portion 410. The length of the pressing portion 430 in the radial direction of the force-bearing portion 410 determines the size of the reserved concave portion 510, and when the reserved concave portion 510 is smaller, the contact area between the potting adhesive 500 and the winding 300 is larger, that is, the fixing effect is better. Preferably, the radial length of the tooth portion 210 is five or more times the length of the pressing portion 430 in the radial direction of the force receiving portion 410.

Since the length of the winding 300 in the radial direction of the core 200 is long and the compressing effect of one compressing portion 430 is limited, the compressing effect can be improved by increasing the number of the compressing portions 430. In one example, two pressing portions 430 are connected to each extension portion 420, and the two pressing portions 430 are spaced apart from each other in a radial direction of the force receiving portion 410.

As shown in fig. 1, the compressing portion 430 is trapezoidal, wherein the width of the connection end between the compressing portion 430 and the extension portion 420 is wider than the width of the end of the compressing portion 430 away from the extension portion 420, that is, the contact surface between the compressing portion 430 and the winding 300 is smaller, and the connection surface between the compressing portion 430 and the extension portion 420 is larger, which not only improves the connection strength between the compressing portion 430 and the extension portion 420, but also increases the contact area between the potting adhesive 500 and the winding 300, thereby improving the fixing effect of the winding 300. Of course, the pressing portion 430 may also be in the shape of a circular truncated cone or a cone.

The force-receiving portion 410, the extending portion 420 and the pressing portion 430 may be integrally formed, but may also be assembled by fastening or screwing.

In summary, the winding pressing tool 400 receives an external acting force through the stress portion 410, and the pressing portion 430 is inserted between two adjacent tooth portions 210 and abuts against the winding 300 sleeved on the tooth portions 210, so that a reserved concave portion 510 opposite to the pressing portion 430 is formed on the potting adhesive 500 for fixing the winding 300, wherein a contact surface between the pressing portion 430 and the winding 300 is smaller than a connection surface between the pressing portion 430 and the extension portion 420, which not only improves a connection strength between the pressing portion 430 and the extension portion 420, but also increases a contact area between the potting adhesive 500 and the winding 300, and further improves a fixing effect of the winding 300. The use of slot wedges or pressing plates is avoided, the working procedures are simplified, and the assembly efficiency is effectively improved.

As shown in fig. 2 to 10, the utility model also provides a winding fixed knot constructs, including casing 100, iron core 200 and winding 300, the iron core 200 is fixed in the casing 100, including a plurality of tooth portions 210 that are around arranging, every tooth portion 210 all overlaps outward and is equipped with winding 300, utilize the winding to compress tightly the portion 430 butt of frock 400 in winding 300, and the inside pouring sealant 500 that fills of casing 100, so that after the solidification form on the pouring sealant 500 with compress tightly the relative reservation concave part 510 of portion 430.
