Abstract
The utility model discloses a fixed structure of a micro motor stator and an end cover. A micro motor comprises a stator (1), an end cover (2) and a rotor (3), wherein, the stator (1) is provided with a stator guiding groove (4) and a fixed groove (7); the end cover (2) is provided with an end cover guiding groove (5), and a steel wire (6) is arranged inside the stator guiding groove (4) and the end cover guiding groove (7); adhesives is coated between the stator (1) and the end cover (2). The micro motor with the fixed structure has small volume, light weight, and high coaxial degree and high installation precision of the stator and the end cover, and overcomes the weaknesses of the prior art.
Description
Technical field
The utility model relates to a kind of micromachine, the fixed structure of particularly a kind of micromachine stator and end cap.
Background technology
The stator and the end cap of micromachine at present commonly used use connected modes such as screw, plastic packaging, riveted joint usually, screw connecting mode needs bigger installing space, plastic packaging, riveted joint connected mode can not adjust motor properties, simultaneously also be unfavorable for improving the axiality and the installation accuracy of stator and end cap, can not satisfy and produce in the needs for the higher performance requirement of micromachine.
The utility model content
Technical problem to be solved in the utility model is, the fixed structure of a kind of micromachine stator and end cap is provided, adopt the micromachine volume of this structure little, in light weight, the axiality and the installation accuracy height of stator and end cap, overcome deficiency of the prior art.
The technical solution of the utility model: this micromachine comprises stator, end cap and rotor, and stator is provided with stator gathering sill and holddown groove, and end cap is provided with the end cap gathering sill, is provided with steel wire in stator gathering sill and end cap gathering sill; Between stator and end cap, be coated with bonding agent.
The above-mentioned micromachine stator and the fixed structure of end cap, stator gathering sill are an annular recess on the stator inner surface.
The fixed structure of aforesaid micromachine stator and end cap, end cap gathering sill are an annular recess of end cap outer surface.
The fixed structure of aforesaid micromachine stator and end cap, holddown groove are a groove of stator outer surface, and holddown groove communicates with the stator gathering sill.
The fixed structure of aforesaid micromachine stator and end cap, the cross-sectional area of steel wire be both greater than the cross-sectional area of stator gathering sill, again greater than the cross-sectional area of end cap gathering sill.
The fixed structure of aforesaid micromachine stator and end cap, stator gathering sill are provided with two internal thread holes.
Compared with prior art, the utility model utilization embeds steel wire in the gathering sill and has limited stator and end cap in axial relative motion, rounds along gathering sill because of steel wire again, so can bear bigger axial tension; In addition, also be coated with bonding agent between stator and the end cap, also eliminated stator and end cap in radially relative motion, thus the complete alternative screw of fixed form, can effectively alleviate finished weight and reduce to assemble volume, help realizing the microminiaturization of motor.In addition, because the offset that does not exist screw to cause, this fixed form also helps to improve the axiality and the installation accuracy of stator and end cap.

Accompanying drawing 1 is for adopting the micromachine assembling schematic diagram of fixed form of the present utility model;
Accompanying drawing 2 is the structural representation of end cap;
Accompanying drawing 3 is that the A-A-A of accompanying drawing 2 is to cross-sectional schematic;
Accompanying drawing 4 is the structural representation of stator;
Accompanying drawing 5 is that the B-B-B of accompanying drawing 4 is to cross-sectional schematic.
Embodiment
Embodiment of the present utility model: require to choose suitable cooperation according to installation accuracy, process an annular recess at stator 1 inner surface, be stator gathering sill 4, process a groove at stator 1 outer surface, be holddown groove 7, holddown groove 7 is communicated with stator gathering sill 4; Process an annular recess at end cap 2 outer surfaces, be end cap gathering sill 5, the spacing that processes 8, two internal thread holes 8 of two internal thread holes on stator gathering sill 4 should be less than the length of holddown groove 7.
According to conventional method produce each parts of micromachine, the luggage of going forward side by side is joined, the assembling of stator 1 and end cap 2 is operated as follows: end cap 2 is filled in stator 1, with stator gathering sill 4 and 5 alignment of end cap gathering sill, select the steel wire 6 of cross-sectional area while for use greater than stator gathering sill 4 and end cap gathering sill 5, steel wire 6 is penetrated the back along the gathering sill circle that detours from holddown groove 7, then the two ends of steel wire 6 are filled in two internal thread holes 8 respectively and used screw-driving.At last, adjust the end cap position, use bonding agent that stator and end cap clung at last to matching requirements.
