Abstract
The utility model provides an improved three position electromagnetic actuating mechanism, comprising two sets of field coils. When the two sets of the coils are electrified solely and both not electrified, output shafts are positioned in three different positions. The positions of the output shafts can be adjusted by screws (3) and can also be adjusted by adjusting second iron core (2).
Description
The utility model relates to a kind of three-position solenoid actuator that has improved.
Three-position solenoid actuator has two groups of magnetizing coils.When two groups of magnetizing coils all during no power, the output shaft of actuator mediates.When two groups of coils were switched on separately, output shaft can two-wayly move.
The United States Patent (USP) of nineteen eighty-two once provided a kind of three-position solenoid actuator No. 4361309.But there are two movable cores in this mechanism, and spring is placed on outside the top of axle, and structure is compact inadequately, and three positions of output shaft fix, and can not adjust.
The purpose of this utility model be to overcome above-mentioned shortcoming propose a kind of compact conformation, position can three-position solenoid actuator.
To achieve these goals, the utility model proposes a kind of three-position solenoid actuator that has improved.Its structure is such.Magnetic conduction casing, a magnetic guiding loop is being fixed at its middle part, first and second liang of group magnetizing coils are arranged in the both sides that are contained in magnetic guiding loop in the housing coaxially, the both sides of two coils have first and second liang of iron cores to link to each other with housing, two iron cores stretch into and form first and second liang of magnetic poles in two coils, an armature is movable in the hole at magnetic guiding loop between two magnetic poles, first and second liang of springs of armature both sides mediate armature, and form working gas gap between first and second liang of magnetic poles
GFirst and
GSecond, output shaft are contained on the armature regularly, stretch out from the endoporus of spring and iron core.Its operating principle is such, when first and second liang of group coils are switched on respectively, and air gap
GFirst and
GSecond is dwindled respectively, and armature is attracted to first, second two iron cores respectively.This two positions is called position first and position second.And when two coils all during no power, the initial position that armature is mediated by two spring resets.Also have a threaded regulating element at the center of second iron core, regulate its compressible or pull-off spring second, thereby change the initial position of armature.
Another kind of form of the present utility model is the second iron core to be made with housing be threaded, thereby rotates the position that the second iron core can change output shaft.
The three-position solenoid actuator that has improved, only with the armature of an activity, spring is in the armature both sides, compact conformation, and armature directly slides in magnet ring, and magnetic resistance is little, and the number of ampere turns of excitation is also little.Need not add any enforceable stopping means when driving load, required actuating force is also little.Owing to above reason, it has that volume is little, in light weight, cost is low, stroke is adjustable and regulates again advantage very easily.
Be described further below in conjunction with illustrated embodiments and accompanying drawing thereof.Fig. 1 is the axial cutaway view of three-position solenoid actuator.
Referring to Fig. 1, the capable mechanism of holding of three-position electromagnetic comprises housing (6), the middle part installs a magnetic guiding loop (8), and A-wire coil assembly (9) and second coil block (7) are arranged in the both sides of housing internal fixation in magnetic guiding loop (8) coaxially.First iron core (13) is fixedlyed connected with housing (6), second iron core (2) becomes to be threaded with housing (6), armature (10) slides in the hole of magnetic guiding loop (8), initial position in the middle of the first spring (11) in left side and the second spring (5) on right side are positioned at armature forms two working gas gaps with the first and second liang of iron cores (13) (2) that stretch into two coils (9) (7)
GFirst and
GSecond, output shaft (12) is fixedly connected with armature (10), stretches out versatilely from the centre bore that first iron core (13) is limited.When first and second liang of coils (9) (7) when switching on separately, output shaft is with respect to the initial position L that moved right left respectively
2And L
1Apart from in-position first and position second.And when becoming another coil electricity by a coil electricity, then output shaft has moved L
1+ L
2Distance.As seen exportable three kinds of two-way displacements of three-position solenoid actuator.Because second iron core (2) becomes to be threaded with housing (6), rotation second iron core (2) just can change position second, also with regard to scalable L
1+ L
2Regulating the back locks with big nut (1).And screw (3) is housed in the centre of second iron core (2), rotating screw (3) compressible and loosen second spring (5) thus move armature (10), change the initial position of output shaft (12), also just regulated L
1And L
2Regulating the back pins with primary nut (4).So three displacements of the utility model are all adjustable.
Obviously, second iron core (2) also can fix with housing (6) and connect or removably be connected with housing (6) by bolt, only adjusts the position that screw (3) is regulated output shaft (12).
Though said mechanism is directly exported the straight line amount of movement, as long as its output shaft is linked to each other with transmission mechanism also and can carry out three controls to other part that moves along a curved path.This three-position solenoid actuator can directly be used for machinery is carried out three bit manipulations.For example come operating diesel machine fuel injection equipment (FIE) in the mode of starting---normal operation---shutdown; and for example go the air-flow control element of operating air conditioner device to pass to heating installation or cold air as required by it with the mode of heating---not exchanging---cooling, this three-position solenoid actuator also can go to drive contact circuit is done three bit maps.This three-position solenoid actuator, except go to do three controls with switching value, the size that also available simulate amount is an electric current goes to do successive control, and purposes is very extensive.
Embodiment shown in Figure 1 is one-sided output, if need bilateral output as long as also fix a last output shaft again as left end at armature (10) right-hand member, second spring (5) is placed on the outside of axle, change screw (3) into swivel nut with holes, push down above-mentioned second spring (5) with its end face and still can keep adjustable function.
