It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Examples
In order to solve the above technical problem, the present embodiment provides a novel motor stator assembly structure, as shown in fig. 1-2, including a casing 10 having an opening formed at one end, a magnetic ring 20 coaxially disposed in the casing 10, an end cover 30 covering the opening end of the casing 10, and further abutting against one end of the magnetic ring 20 through the end cover 30, so that the magnetic ring 20 is fixed in the casing 10, thereby avoiding the existing manner of fixing through glue, and improving stability. At least two positioning bosses 11 protruding towards the inner side are formed on the casing 10, positioning grooves 21 embedded in the positioning bosses 11 are formed at the end parts of the magnetic ring 20, the magnetic ring 20 and the casing 10 are in clearance fit, after the magnetic ring 20 is installed in the casing 10, the positioning bosses 11 of the magnetic ring 20 are embedded in the casing 10, so that the magnetic ring 20 and the casing 10 are quickly positioned and cannot relatively rotate, the magnetic ring 20 is ensured not to be reversely installed, the magnetic ring 20 is fixed in the casing 10 through the end cover 30, the assembling structure avoids the problem that the magnetic ring 20 and the casing 10 are damaged and scrapped due to interference fit, and meanwhile, the assembling precision is high, and the assembling efficiency is high.
Furthermore, in order to prevent the magnetic ring 20 from being incorrectly assembled, a plurality of positioning bosses 11 may be provided on the housing 10, as shown in fig. 3, at least two positioning bosses 11 have different sizes. Wherein, location boss 11 is provided with two in this embodiment to the symmetry sets up at the casing 10 inside wall, and two location boss 11's size is inequality, forms the constant head tank 21 that corresponds to two location boss 11 sizes respectively at the 20 tip of magnetic ring simultaneously, and then through the location boss 11 of equidimension not, plays the effect of preventing slow-witted in the assembly process, improves the equipment degree of accuracy, guarantees motor assembly quality.
After the magnetic ring 20 is installed in the casing 10, in order to fix the magnetic ring 20 in the casing 10, as shown in fig. 4, an abutting block 31 is formed on an end surface of the end cover 30, and after the end cover 30 covers an end portion of the casing 10, the abutting block 31 of the end cover 30 abuts against an end surface of the magnetic ring 20, so that the magnetic ring 20 is fixed in the casing 10, and the magnetic ring 20 is fixed.
Further, a snap ring 32 is formed on the outer peripheral surface of the end cap 30, and the snap ring 32 is fitted to the inner side surface of the end portion of the casing 10.
