Description

Technical Field

[0001] The utility model relates to the technical field of stator winding end plates, in particular to a stator winding end plate. Background Art

[0002] The stator winding end plate is an important component in the motor, mainly used to fix and support the stator winding, that is, the coil in the motor. The stator winding end plate is usually made of insulating materials such as plastic, epoxy resin, etc. Existing motors will generate vibration and mechanical stress during operation. These forces act on the stator winding end plate for a long time, which may cause the fixings to loosen or the material to fatigue, thereby causing the winding end plate to fall off, affecting the electronic operation. Therefore, a stator winding end plate is proposed. Utility Model Content

[0003] The main purpose of the present invention is to provide a method for effectively solving the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a stator winding end plate, including an end plate body, a plurality of winding plates arranged on the end plate body for winding enameled wire, a baffle arranged on the winding plate, and a winding groove formed between the winding plates, characterized in that it also includes a limiting step arranged at the bottom of the winding groove and adapted to the step on the stator core, and a plurality of inclined cotter pins arranged at the bottom of the winding plate and adapted to the fixing hole on the stator core.

[0005] Preferably, it also includes a plurality of positioning conical columns arranged at the bottom of the winding plate and adapted to the positioning holes on the stator core.

[0006] Preferably, a toothed damping strip is provided on the outer side of the limiting step.

[0007] Preferably, a limiting strip for limiting the installation position of the end plate body is provided at the bottom of the winding plate.

[0008] The present utility model has the following beneficial effects: by setting the limiting steps, the resistance of the contact surface between the end plate body and the stator core is increased. Each limiting step corresponds to a step connected to the stator core, and the shape of the limiting step matches the shape of the step set on the stator core, thereby increasing the adaptability of the end plate body and the stator core; by setting the inclined cotter pin, the inclined cotter pin is pressed so that the outer surface of the inclined cotter pin is squeezed inwardly, so that the diameter of the inclined cotter pin becomes smaller, and it can quickly enter the fixing hole on the stator core. After entering, the opening is reset, and the inclined cotter pin is expanded, which can effectively prevent the end plate body from being separated from the stator core when the motor vibrates or is pulled out by external force, thereby increasing the fit firmness of the end plate body 1 and the stator core. By setting the positioning cone, the end plate body 1 and the stator core can be quickly positioned and installed.

[0009] The toothed damping strip increases the resistance of the contact surface between the limit step and the stator core, effectively preventing the end plate body or the stator core from being separated by external forces during the operation of the motor, thereby affecting the operation of the equipment. It forms a double lock with the inclined cotter pin, so that the end plate body can be firmly fixed on the stator core.

[0010] By setting the limiting strip, the cooperation between the end plate body and the stator core is limited, and the contact area between the end plate body and the stator core is also increased, thereby increasing the strength of the end plate body. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figure 1-4As shown, a stator winding end plate comprises an end plate body 1, a plurality of winding plates 2 arranged on the end plate body 1 for winding enameled wire, a baffle 3 arranged on the winding plate 2, and a winding groove 4 formed between the winding plate 2 and the winding plate 2, characterized in that it also includes a limiting step 5 arranged at the bottom of the winding groove 4 and adapted to the step on the stator core, and a plurality of inclined cotter pins 7 arranged at the bottom of the winding plate 2 and adapted to the fixing hole on the stator core; by setting the limiting step 5, the resistance of the contact surface between the end plate body 1 and the stator core is increased, and each limiting step 5 corresponds to a fixed connection. A step is formed on the stator core, and the shape of the limiting step 5 matches the shape of the step provided on the stator core, thereby increasing the adaptability of the end plate body 1 to the stator core; through the provision of the inclined cotter pin 7, the inclined cotter pin 7 is pressed to squeeze the outer surface of the inclined cotter pin inwardly, so that the diameter of the inclined cotter pin 7 becomes smaller, and it can quickly enter the fixing hole on the stator core. After entering, the opening is reset, and the inclined cotter pin 7 is expanded, which can effectively prevent the end plate body 1 from being separated from the stator core when the motor vibrates or is pulled out by external force, thereby increasing the firmness of the fit between the end plate body 1 and the stator core.

[0018] In one embodiment, it also includes a plurality of positioning conical columns 6 arranged at the bottom of the winding plate 2 and adapted to the positioning holes on the stator core; the arrangement of the positioning conical columns 6 facilitates the rapid positioning and installation of the end plate body 1 and the stator core.

[0019] In one embodiment, a toothed damping strip 8 is provided on the outer side of the limiting step 5; the provision of the toothed damping strip 8 increases the resistance of the contact surface at the connection between the limiting step 5 and the stator core, effectively preventing the end plate body 1 or the stator core from being affected by external forces and detaching during the operation of the motor, thereby affecting the operation of the equipment; and forms a double locking with the inclined cotter pin 7, so that the end plate body 1 can be firmly fixed on the stator core.

[0020] In one embodiment, a limiting strip 9 is provided at the bottom of the winding plate 2 for limiting the installation position of the end plate body 1; by setting the limiting strip 9, the cooperation between the end plate body 1 and the stator core is limited, and the contact area between the end plate body 1 and the stator core can also be increased, thereby increasing the strength of the end plate body 1.

[0021] During the installation process of the present invention, the positioning conical column 6 is first aligned with the positioning hole on the stator core, and the limiting step 5 is aligned with the step on the stator core, and the inclined cotter pin 7 is aligned with the fixing hole on the stator core. Then, the end plate body 1 is pressed, and the inclined cotter pin 7 is squeezed inward by force until it completely enters the fixing hole on the stator core. The opening of the inclined cotter pin 7 is reset, and the limiting step 5 is inserted into the step on the stator core. The end plate body 1 is firmly fixed on the stator core through the double locking of the toothed damping strip 8 on the outside of the limiting step 5 and the inclined cotter pin 7.
