The utility model discloses a thereby locating component that sets up on the skeleton body installs the coil on stator core to solved the unstable and position of installation of terminal on the iron core and taken place the problem that deflects before wire winding, thereby influenced wire-wound quality, leaded to wire-wound back stator condemned problem.

Description

Stator winding framework

Technical Field

The utility model relates to the field of electric machines, concretely relates to stator bobbin.

Background

Stator winding skeleton among the prior art is owing to assemble the skeleton on stator core through equipment, because the detection that does not possess skeleton installation stability of equipment, the fixed of skeleton is just advanced to fix on stator core by the winding enameled wire in addition to consequently lead to the problem that the installation of terminal on the iron core is unstable and the position takes place to deflect before the wire winding, thereby has influenced wire-wound quality, leads to wire winding back stator to scrap. Therefore, it is necessary to provide a stator bobbin with a stable installation.

Disclosure of Invention

The utility model aims at solving the problem that the winding quality caused by the unstable installation of the existing stator winding framework on the stator core.

In order to achieve the aim, the utility model provides a stator winding skeleton, which comprises a skeleton body, be equipped with a plurality of winding displacement posts that are used for twining the enameled wire along circumference on the skeleton body, be equipped with the wire winding passageway between the winding displacement post, its characteristic still includes still be equipped with the locating component that the skeleton body of being convenient for was firm to be installed on stator core on the skeleton body.

Preferably, the positioning assembly comprises a plurality of positioning columns arranged on the framework body and a plurality of annular clamping plates arranged on the positioning columns.

Preferably, the positioning assembly comprises a plurality of positioning columns arranged on the framework body and a plurality of clamping tooth structures obliquely arranged on the positioning columns.

Preferably, the winding displacement column is provided with a baffle plate for preventing the enameled wire from falling off.

Preferably, the wire arranging column, the wire winding channel, the framework body, the positioning assembly and the framework body are integrally formed in an injection molding mode.

The utility model has the advantages that: thereby the locating component who sets up on the skeleton body will install the coil on stator core to the installation of terminal on the iron core is unstable and the position takes place the problem of deflecting before wire winding has been solved, thereby has influenced wire-wound quality, leads to wire-wound back stator condemned problem.

Detailed Description

The following description will be made with reference to the embodiments and the accompanying drawings for a stator bobbin of the present invention.

Example 1

As shown in fig. 1-3: the utility model discloses a skeleton body 1, be equipped with a plurality of winding displacement posts 2 that are used for twining the enameled wire along circumference on the skeleton body 1, be equipped with wire winding passageway 3 between the winding displacement post 2, still be equipped with the skeleton body of being convenient for on the skeleton body 1 and stabilize locating component 4 of installing on stator core. The positioning assembly 4 comprises a plurality of positioning columns 401 arranged on the framework body 1 and a plurality of annular clamping plates 402 arranged on the positioning columns 401; the winding displacement column 2 is provided with a baffle 201 for preventing the enameled wire from falling off; the winding displacement column 2, the winding channel 3, the framework body 1, the positioning assembly 4 and the framework body are integrally formed by injection molding.

When the utility model is applied, the stator core is provided with a positioning hole matched with the positioning component of the framework body, then, by inserting the positioning column 401 into a positioning hole on the stator core, the framework body is extruded towards the direction of the core by the equipment, so that the annular clamping piece 402 on the positioning column 401 is attached to the hole wall of the positioning hole of the stator core, and along with the downward extrusion force of the equipment, the positioning hole on the stator core generates opposite force to the annular clamping piece 402, the annular clamping piece is turned up towards the force application direction to generate deformation, so that the positioning column is extruded and more stably fixed in the positioning hole of the stator core, thereby installing the skeleton body and providing the effect of fixing in advance and fixing a position on stator core, consequently avoided the installation of terminal on the iron core unstable and the problem that the position takes place to deflect before the wire winding to influenced wire-wound quality, leaded to wire-wound back stator condemned problem.

Example 2

Referring to fig. 1 and 4, the difference between this embodiment and embodiment 1 is that the positioning column 401 replaces the annular card with a plurality of latch structures 403 obliquely disposed on the positioning column 401. When the positioning column is inserted into the positioning hole on the stator core, the hole wall of the positioning hole generates extrusion force on the latch structure 403 on the positioning column, and the latch structure also generates reaction force on the hole wall of the positioning hole, so that the stability of the positioning column in the positioning hole of the stator core is improved; thereby installing the skeleton body and providing the effect of fixing in advance and fixing a position on stator core, consequently avoided the installation of terminal on the iron core unstable and the problem that the position takes place to deflect before the wire winding to influenced wire-wound quality, leaded to wire-wound back stator condemned problem.

As shown in the figure: be equipped with on the stator core with reference column assorted guiding hole, the skeleton body passes through the guiding hole that the reference column inserted on the stator core, realizes that the skeleton body is firm to be connected on the stator core fast.

The utility model discloses a use method, with the skeleton body through the reference column install the guiding hole on the stator core, through the stator coiling machine, twine the enameled wire on the winding displacement post, draw the enameled wire on the different winding displacement posts at last.

The above-mentioned embodiment is right the utility model discloses an explanation, it is not right the utility model discloses a limited, any right the scheme after the simple transform of the utility model all belongs to the protection scope of the utility model.
