The positioning post is buckled in a position limiting hole which is arranged on the top surface of the shell in a predetermined mode. The guide frame positioning structure of a shell of a small size motor can be prompted to achieve the practical efficacy and purposes of combined positioning precision, excursion prevention, convenient processing, convenient operation, energy saving and consumption reduction.

Description

Miniature motor housing saddle location structure

Technical field

The utility model is the structure of relevant a kind of miniature motor housing saddle.

Background technology

The conventional small motor is (as Fig. 1, shown in 2) be to be installed with stator 11 and rotor 13 in its housing 10, central shaft 14 bottoms of this rotor 13 are pivot frame axle sleeves 16 in housing 15 bottoms, and the driving section 17 of central shaft 14 outer ends be pass housing 10 and saddle 20 wear

mouthfuls

18,19, and it is framework axle sleeves 21 in saddle 20 outer ends that central shaft 14 drives section 17 outer ends, wherein saddle 20 be in advance with a solid welding group in the top of housing 10, when so assembling because of its actual spot welding, since housing 10 and saddle 20 wear mouthfuls 18, the situation of 19 dislocation skews is very frequent, as shown in Figure 3, cause the center skew of rotor 13 central shafts 14 pivot framves and can't bear use, the auxiliary fixture that installs contraposition again separately additional also can not improve the shortcoming of dislocation skew fully, the inconvenience that but causes process operation on the contrary also makes the required electric energy of spot welding increase the leakage loss possibility of non-location of short circuit.

Therefore, how researching and developing a kind of location structure of novel miniature motor housing saddle, looked forward to by the dealer in fact, also is that the target and the direction of breakthrough are developed in the required effort of relevant dealer.

In view of this, the inventor this in manufacturing development and the design experiences of being engaged in Related product for many years, at above-mentioned target, in detail design and scrupulous assessment back eventually the utility model of a true tool practicality.

Summary of the invention

Main purpose of the present utility model is that a kind of miniature motor housing saddle location structure is being provided, mainly to be nationality wear that mouthful frame pipe that following one is extended is directly worn wearing mouthful of frame motor shell and in inboard rivet clasp by saddle for it, cooperate the reference column on the saddle involutory in the default spacing hole of housing end face, the structural design of its specific combination must impel it to reach practical effect and purpose that the precise combination location prevents to be offset, to make things convenient for process operation and saves energy loss.

The purpose of this utility model is achieved in that

A kind of miniature motor housing saddle location structure is provided, the inner group of its motor shell is provided with stator, the inside of this stator is formed with rotor hole, and this rotor hole content is provided with rotor, this centre of rotor axle bottom is the axle sleeve of pivot frame in the motor shell bottom, and the driving section of central shaft outer end, it is the mouth of wearing that passes this housing and saddle, and it is the axle sleeve of pivot frame in this saddle outer end that this central shaft drives the section outer end, wherein this saddle is to organize admittedly in advance on the top of this housing, it is characterized in that: it is that downward one is extended with the frame pipe that this saddle is worn mouth, and this pipe is to wear frame wearing mouth and making this pipe end edge expansion build-in wear a mouthful inboard in this in this housing, convex with reference column with this pipe homonymy on this saddle again, and that this reference column gets is involutory in the default spacing hole of this housing end face.

Advantage of the present utility model and good effect are:

One, directly wears the wear mouth of frame because the utility model saddle is worn a mouthful frame pipe that extends, must make the assembling of housing and saddle, cut off the possibility of not having the skew dislocation, and thoroughly reach the main effect and the purpose of precise combination location in housing.Two, the spacing hole of the reference column of saddle and housing is involutory, and the effect of saddle and the stop of housing rotation direction is provided.Three, get rid of the shortcoming that traditional spot weld operation and contraposition auxiliary fixture make the process operation inconvenience, also can get rid of the leakage loss of electric energy simultaneously.

Embodiment

At first, please consult the 4th earlier, shown in 5 figure, the utility model provides a kind of miniature motor housing saddle location structure, its motor shell 30 inner groups are provided with stator 31, the inside of this stator 31 is formed with rotor hole 32, and rotor hole 32 contents are provided with rotor 33, central shaft 34 bottoms of this rotor 33 are framework axle sleeves 36 in motor shell 35 bottoms, and the driving section 37 of central shaft 34 outer ends, be pass housing 30 and saddle 40 wear

mouthfuls

38,39, and it is pivot frame axle sleeves 41 in saddle 40 outer ends that central shaft 34 drives section 37 outer ends, wherein saddle 40 is to organize admittedly in advance on the top of housing 30, be primarily characterized in that: it is that downward one is extended with frame pipe 42 that this saddle 40 is worn mouth 39, and frame pipe 42 is to wear frame to wear mouthfuls 38 in housing 30, and make frame pipe 42 ora terminalis expansion build-in in wearing mouthful 38 inboards, convex with reference column 43 with frame pipe 42 homonymies on the saddle 40 again, and this reference column 43 must be involutory in the default spacing hole 44 of housing 30 end faces.
