Description
Technical field
Motor is the utility model is related to, especially a kind of dither motor.
Background technology
The rotor afterbody of vibrating motor typically sets an elastic component, and one end of elastic component is fixed on stator or motor
On housing.When the forward and reverse energization of motor, rotor rotation can distort elastic component, and it can rely on elasticity after current interruptions
The resilience of part, which is realized, to be resetted.
Such as existing patent：Reciprocal dither motor (the patent No.：201310685800.7), its elastic component is to pass through bolt
The form of fastening is connected on the fixed block provided with notch, then fixed block is fixed on electric machine casing, and these parts are more
Tiny, assembling is extremely inconvenient, and elastic component easily occurs deforming when screw tightens, offset, and causes elastic feedback to differ, stable
Property it is poor, reduce motor working efficiency.
The content of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of dither motor.
Technical scheme is used by the utility model solves its technical problem：
A kind of dither motor, including motor body, the motor body include determining in upper and lower two groups of frame-type docking
Son and the rotor assembly positioned at inframe, the motor body both ends are respectively installed with forward and backward end cap, in the forward and backward end cap
Be provided with bearing, the rotor assembly both ends are worn to connect and are fixed on the bearing, the rotor assembly by rotating shaft, magnet is installed
Plastic stent and elastic component form；Realize and fix that its end is then with plastic stent integrated injection molding in the front end of the elastic component
Integrated injection molding has the Access Division being fixed on rear end cap.
The Access Division is the cylindrical body of the vertical rotor axis；The rear end cap is provided with the fixation chimeric with Access Division
Groove.
The forward and backward end cap is spliced by upper and lower two parts, and can be by the motor during upper and lower shell splicing
The both ends of main body connect and fix.
The elastic component is metal clips.
The injection molding end of the elastic component is provided with neck.
The rotating shaft being made of metal and the plastic stent integrated injection molding.
The beneficial effects of the utility model are：Rotor assembly of the present utility model is by making the front end of elastic component and plastics branch
Frame integrated injection molding, which is realized, to be fixed, and then integrated injection molding has Access Division for end, one end of elastic component is connected to rear end solid and reliablely
Cover, assembling is more simple, and elastic component is tightly combined with Access Division, and precision is high, can improve the stability of motor amplitude, increases
Forceful electric power machine intensity, improve electrical machinery life.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the utility model motor；
Fig. 2 is the decomposing schematic representation of the utility model motor；
Fig. 3 is the structural representation of the utility model rotor assembly；
Fig. 4 is the sectional view of the utility model rotor assembly.
Embodiment
Referring to figs. 1 to Fig. 4, a kind of dither motor, including motor body 1, motor body 1 include docking in frame-type
Upper and lower two groups of stators 11 and the rotor assembly 12 positioned at inframe, the both ends of motor body 1 be respectively installed with drive end bearing bracket 7, rear end
Lid 8, be provided with bearing 9 in forward and backward end cap, the both ends of rotor assembly 12 are worn to connect and are fixed on bearing 9, rotor assembly 12 by rotating shaft 3,
The plastic stent 4 and elastic component 5 for being provided with magnet are formed；The front end of elastic component 5 and plastic stent 4 made of metal clips
Integrated injection molding, which is realized, to be fixed, and then integrated injection molding has the Access Division 6 being fixed on rear end cap 8 for its end, and assembling is more simple,
And elastic component is tightly combined with Access Division, precision is high, can improve the stability of motor amplitude, strengthens motor intensity, improves electricity
The machine life-span.
Further, drive end bearing bracket 7, rear end cap 8 are spliced by upper and lower two parts, when being spliced by upper and lower two parts
The both ends of motor body 1 are connected and fixed, without as separately setting electric machine casing in the past, reducing manufacturing cost.
Therefore, Access Division 6 can be designed as to the cylindrical body of the axis of vertical rotor component 12, and in the upper part of rear end cap 8
Or lower part is provided with the fixing groove 81 chimeric with Access Division 6, Access Division is consolidated in the lump by the splicing of two parts up and down of rear end cap 8
Fixed, assembling is easy, more solid and reliable.
Further, the rotating shaft 3 being made of metal and the integrated injection molding of plastic stent 4, it is more solid and reliable；And elasticity
Two injection molding ends of part 5 can be provided with the neck 51 of depression or projection, and plastics can be poured in neck during injection, be not easy to release.
Clever structure of the present utility model is reasonable, and assembling is more simple, and elastic component 5 is tightly combined with Access Division 6, precision
Height, improve stability and the life-span of motor amplitude.
