In the embodiment of the present application, the assembly jig may also be referred to as an assembly jig, for example, as a component in a production line, and in an assembly process, the housing 101 may be fixed to the assembly jig, and then a subsequent motor assembly work may be performed. For example, the housing 101 may be fixed to an assembly jig by a fixing member such as a pin, and a force may be applied to the linear positioning portions 1015a and/or 1015b of the housing 101, so that the housing 101 can be reliably fixed with respect to the assembly jig, thereby ensuring accurate positioning of the housing 101. In the embodiment of the present application, a component corresponding to the positioning portion 1015a and/or 1015b may be disposed in the assembly fixture to apply a force to the positioning portion of the housing 101, for example, the component may be a slider, a push block, or the like, which is not limited in the embodiment.

In the present embodiment, the positioning portion is a linear portion on the outer periphery of the rim portion 1012, and may be, for example, a portion shown as 1015a or 1015b in fig. 1 and 2, or both 1015a and 1015b may be used as the positioning portion, which is not limited in the present embodiment, and in the present embodiment, the linear portion may be a straight line or a substantially straight line; the positioning portion 1012 may have other shapes, such as a concave shape or a convex shape, on the outer periphery of the rim portion 1012.
