Description
Technical field
The utility model relates to the quartz watch field, relates in particular to a kind of precision positioning device that is applied to the timepiece movement motor.
Background technology
Present domestic quartz watch movement to what the fixed form of the stator piece of motor and iron-core coil mainly adopted is: 1, screw is fixed mode, and its shortcoming is that cost height and assembling speed are slow; 2, not rivet hot fixed form behind the pressure tight loop (nail); Its shortcoming is when assembling rivet hot compressing tablet or in transit or tight loop (nail) is easy in other vibration processes rebounds; Loosening phenomenon occurs, cause the imprecision that contacts between stator piece and the iron-core coil, influence magnetic conduction; 3, press tight loop (nail) after heat rivet clasp decide mode, shortcoming is to increase operation, and tight loop (nail) dismantles extremely inconvenience after rivet hot, and part is scrapped easily, thereby has caused the waste of resource.
Summary of the invention
In order to overcome above-mentioned defective, the purpose of the utility model provided a kind of simple installation, repacking cost low, can realize that core motor is difficult for displacement, the difficult precision positioning device that becomes flexible of the stator piece on positive plate and the core motor and iron-core coil especially.
For realizing above-mentioned purpose, the technical scheme of the utility model is:
A kind of precision positioning device that is applied to the timepiece movement motor, it comprises motor and positive plate, said motor is provided with stator piece and iron-core coil, it is characterized in that:
Said positive plate acts directly on the keeper of stator piece and iron-core coil, makes the keeper difficult drop-off, thereby strengthens the fastening effect of keeper to stator piece and iron-core coil;
Perhaps said positive plate is provided with between itself and stator piece and iron-core coil and urges parts, and positive plate can be acted directly on stator piece or iron-core coil or both through urging parts;
Perhaps said positive plate is provided with between itself and stator piece and iron-core coil and urges parts; Positive plate can be acted directly on the keeper of stator piece and iron-core coil through urging parts; Make the keeper difficult drop-off, thereby strengthen the fastening effect of keeper stator piece and iron-core coil.
Said keeper comprises that one has the reference column and a clench nail of middle part through hole, and said stator piece and iron-core coil are nested with successively on reference column, and the middle through hole of reference column is stretched in the lower end of said clench nail, and the clench nail head of a nail is pressed on the iron-core coil; The said parts that urge are located between the positive plate and the fastening head of a nail, make positive plate to act on the fastening head of a nail through urging parts, then stator piece and iron-core coil are played fastening effect.
Described urge that parts are provided in a side of on the positive plate and with one or more salient points of iron-core coil opposite position.
The usefulness of technique scheme is:
1, make the elasticity that clench nail can be through the positive plate salient point, prevent when the rivet hot compressing tablet or in transportation or in other vibration processes clench nail break away from reinforcement effect to iron-core coil and stator piece, make the contact between iron-core coil and the stator piece tightr.
2, reduce cost, accelerate assembling speed, be easy to dismounting or refitting simultaneously, reduced because of assembling the improper wasting of resources that causes.
3, increase salient point at positive plate, can reduce the thickness of the fastening head of a nail, avoid " top-heavy " phenomenon, be convenient to robotization and select materials.
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model.
Embodiment
Embodiment
A kind of precision positioning device that is applied to the timepiece movement motor as shown in Figure 1 comprises that other functional part and the machine core shell of motor, positive plate 1, movement, said motor are provided with stator piece 2 and iron-core coil 3; And be fastened on the base of a machine core shell through clench nail 4, on positive plate 1, establish a positive plate salient point 6, the position of positive plate salient point 6 is satisfied salient point and can be leaned on the fastening head of a nail; And make positive plate 1 have certain elastic potential energy; Make stator piece 2 and the pressure of iron-core coil 3 through positive plate 1, contact closelyr, clench nail 4 is difficult for becoming flexible simultaneously; Thereby it is loosening that stator piece 2 and iron-core coil 3 are difficult for, and realizes that then core motor is difficult for displacement.
The invention emphasis:
Stator piece of this New-type electric machine and iron-core coil lean on stator piece and iron-core coil the positive plate indirectly-acting through utilizing the elastic force of positive plate, and realize its fastening effect.Comprise 2 kinds of schemes: 1) make positive plate directly lean stator piece and iron-core coil separately or on the common keeper; 2) urge parts establishing between positive plate and stator piece and iron-core coil or between on the keeper of stator piece and iron-core coil.
Said stator piece of the foregoing description and iron-core coil are installed in on the positioning piece; Certainly different cassette mechanism also different situations possibly occur; Be that both are not installed in on the positioning piece; Then positive plate can add strong fix separately to stator piece, also can ought solely add strong fix to iron-core coil, also can add strong fix to both simultaneously.
The foregoing description has been introduced the technical scheme of a kind of positive plate indirectly-acting on stator piece and iron-core coil; Salient point is the parts that urge of emphasis of the present invention on the positive plate; But this salient point makes positive plate formation elastic force and this elastic force transfer function on stator piece and iron-core coil, and its quantity obviously can be set at more than one as required.
Said stator piece of the foregoing description and iron-core coil are nested with successively on the reference column (7 among Fig. 1) that has the middle part through hole; Said iron-core coil is provided with a clench nail; The middle through hole of reference column (7 among Fig. 1) is stretched in the lower end of said clench nail; The clench nail head of a nail is pressed on the iron-core coil, and the said parts that urge are located between the positive plate and the fastening head of a nail, makes positive plate to act on the fastening head of a nail through urging parts; Then stator piece and iron-core coil are played fastening effect; Obviously all quartz watch movements that is applied to, and spacing by this novel technical characterictic to utilize positive plate that stator piece and iron-core coil are carried out, there are pair stator piece and the iron-core coil to adopt any locator meams all at the novel protection domain of basis.
