Abstract
A kind of motor housing structure, described motor housing is cylindrical housing, the upper end of motor housing is evenly equipped with two to six button tongues, described button tongue is triangular in shape, button tongue while be connected with motor housing with the axis being parallel of motor housing, the button following self-clinching tongue of tongue starts to tilt upward with the point that is connected of motor housing, detains tongue and be pressed into rotatably in motor housing with the limit that is connected of motor housing around button tongue, on the upper limb being pressed in the stator core loading motor housing lower end below of button tongue during use.Beneficial effect is: can reliablely and stablely stator core is fixed in the cylindrical housing of motor, have that structure is simple, less investment, cost is low, production efficiency is high and fraction defective is low advantage.
Description
Technical field
The utility model relates to machine field, especially relates to a kind of motor housing structure.
Background technology
The stator core of motor normally adopts following several mode to be fixed in the cylindrical housing of motor:
1. stator core and cylindrical housing carry out interference fit, namely utilize hot jacket or large-sized hydraulic press directly stator core to be installed in cylindrical housing.Problems existing is: power consumption is large, and production efficiency is low;
2. the button tongue be pressed into vertically in the middle part of cylindrical housing is set on cylindrical housing, utilizes button tongue to position stator core.Problems existing is: require high to the accuracy of manufacture of stator core, fixing poor reliability, finally causes the bad phenomenon of friction rotor stator;
3. screwed hole is set on cylindrical housing, screws in, be pressed on the outside of stator core with screw from tubular shell.Problems existing is: easily cause stator core to be out of shape, and produces the bad phenomenon of friction rotor stator.
Summary of the invention
It is simple that main inventive object of the present utility model is to provide a kind of structure, stator core can be fixed on the motor housing structure in the cylindrical housing of motor reliable and stablely.
The utility model technical scheme used is: a kind of motor housing structure, described motor housing is cylindrical housing, the upper end of motor housing is evenly equipped with two to six button tongues, described button tongue is triangular in shape, button tongue while be connected with motor housing with the axis being parallel of motor housing, the button following self-clinching tongue of tongue starts to tilt upward with the point that is connected of motor housing, detain tongue during use to be pressed into rotatably in motor housing with the limit that is connected of motor housing around button tongue, on the upper limb being pressed in the stator core loading motor housing lower end below of button tongue.
Button tongue described here is triangular in shape, refers to button tongue by the shape after open and flat one-tenth plane.The utility model, by the button sublingual limit structure tilted, can than the dimensional tolerance adapting to stator core significantly, and button tongue is not easy in use to get loose, thus can reliablely and stablely stator core be fixed in the cylindrical housing of motor, have that structure is simple, less investment, cost is low, production efficiency is high and fraction defective is low advantage.
As preferably, the upper end of motor housing is evenly equipped with four button tongues, button tongue below and the angle of horizontal plane be more than or equal to 10 °, be less than or equal to 25 °.This preferred version, structure is simple, and processing and manufacturing cost is low, and result of use is good.
As preferably, detain the rectangular triangle of tongue.This preferred version, structure is simple, and processing and manufacturing cost is low.
In sum, the beneficial effect that the utility model brings is: can reliablely and stablely stator core is fixed in the cylindrical housing of motor, have that structure is simple, less investment, cost is low, production efficiency is high and fraction defective is low advantage.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1, motor housing described in the utility model is cylindrical housing, the upper end of motor housing is evenly equipped with two to six button tongues 1, described button tongue 1 is triangular in shape, button tongue 1 while be connected with motor housing with the axis being parallel of motor housing, the following 1.1 self-clinching tongues 1 of button tongue 1 start to tilt upward with the point that is connected of motor housing, detain tongue 1 during use to be pressed into rotatably in motor housing with the limit that is connected of motor housing around button tongue 1, on the upper limb being pressed in the stator core loading motor housing lower end below of button tongue 1, thus effectively can prevent stator core play in motor housing.The concrete mounting structure of stator core in motor housing, because being known technology, does not repeat at this.As preferably, the upper end of the present embodiment motor housing is evenly equipped with four button tongues 1, and being more than or equal to 10 ° with the angle of horizontal plane, being less than or equal to 25 ° below of button tongue 1, is preferably 15 °, the rectangular triangle of button tongue 1.
The specific embodiment of the above is only the utility model preferably execution mode, not limits concrete practical range of the present utility model with this.The equivalence change that all shapes according to the utility model, structure are done ought to all be included in protection range of the present utility model.
