Detailed Description
The present invention will be further described with reference to the accompanying drawings. The utility model provides a fan motor stator and shell rapid Assembly structure which characterized in that: the motor stator fixing device comprises a fixing shell 1, wherein the fixing shell 1 is in a cylindrical shape with an opening and a bottom, a sinking platform 2 is arranged on an inner hole of the fixing shell 1, the motor stator 3 is sleeved in the fixing shell 1 and is born on the sinking platform 2 through the lower end face of the fixing shell, and a plurality of fixing screws 4 penetrate through the fixing shell 1 to be in threaded connection with the motor stator 3, so that the motor stator 3 and the fixing shell 1 are connected into a whole.
The fixing screw 4 is a self-tapping screw which is screwed with the motor stator 3 after drilling through the fixing shell 1.
The excircle of the motor stator 3 is provided with a plurality of connecting bosses 5, and the fixing screws 4 penetrate through the fixing shell 1 and are in threaded connection with the connecting bosses 5.
The fixed shell 1 is in a two-section open shape with a large upper part and a small lower part, and a sinking platform 2 is formed at the joint of the two sections of shells.
The working principle is as follows: the shell in this case sets up big-end-up's two sections formula open tube-shapes, and the junction of two sections casings forms heavy platform 2. Therefore, the shell can be formed through the die in an integrated mode, when the motor stator is assembled with the shell, the motor stator only needs to be placed in an inner hole of the shell, and the outer circle of the motor stator and the inner hole of the shell are coaxially matched. Meanwhile, the motor stator is pressed inwards, so that the lower end face of the motor stator is in close contact with the sinking platform, and the axial positioning of the motor stator is achieved. Through the axial and radial dual positioning, the relative installation position between the motor stator and the shell can be accurately positioned.
In order to prevent the motor stator and the shell from displacing in the later use process, the self-tapping screw directly penetrates through the shell to be in threaded connection with the motor stator, and the relative position between the shell and the motor stator is locked, so that the fan motor can work stably and efficiently for a long time.
Furthermore, in order to prevent the self-tapping screw from easily touching the coil during installation, the motor stator in the present case may further have a plurality of connection bosses 5 on an outer circle thereof, and the fixing screw 4 penetrates through the fixing shell 1 and is screwed with the connection bosses 5.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed.
