Abstract
The utility model discloses an electric actuator of reciprocating rotation with a fixed angle. The electric actuator of reciprocating rotation with a fixed angle of the utility model is provided for simplifying the structure and reducing faults. The utility model comprises a U-shaped stator (1), two fan-shaped magnetic poles (2) and (3), non-magnetic conductive materials (8), a rotor (4), a rotating shaft (5) and magnet coils. The rotor (4) can make the reciprocating rotation by dint of the electromagnetic power in the angle which is smaller than 180 DEG and limited by the two fan-shaped magnetic poles. The utility model can replace an angle stroke electric actuator to drag the load which just needs the reciprocating rotation with a fixed angle.
Description
The utility model is to come and go the electric operator of rotation with fixed angle.
As everyone knows, the angle stroke electric actuator by motor, decelerator and position transducers (or travel switch) are formed jointly can drag the spinning movement that different angles are done in its load after receiving the different signals of telecommunication.At present, only need also usually use similar above-mentioned mechanism in the mechanical device with the round rotation of certain fixing angle at some.As the pistol electric target of sports tournament aspect, only need target body to do the spinning movement that comes and goes 90 degree.In order to realize this angle rotation of fixing 90 degree, the electronic target of SQB type that Kunming physical culture electronic equipment research institute produces has just used the comprehensive organ that comprises motor, reduction box and travel switch.The spy opens the target that clear 54-66599 document introduced and has also used the comprehensive organ that comprises motor and slow down machinery.These complicated mechanisms have not only improved cost but also have increased failure rate.
The purpose of this utility model is, provide a kind of simple in structure, easy to use, can be to come and go the electric operator of rotation less than certain fixed angle of 180 degree.
The electric operator that comes and goes rotation with fixed angle provided by the utility model as shown in the figure.The two ends symmetry of U-shaped stator (1) is fixed two fan-shaped magnetic poles (2) and (3).Rotor (4) is fixed together with rotating shaft (5).Because stopping of fan-shaped magnetic pole (2) and (3) so rotor (4) can only rotate in the fixed angle less than 180 degree that two fan-shaped magnetic poles are limited.
When ferrimagnet such as silicon steel sheet or electrician's soft iron is all used in rotor (4) and stator (1) and fan-shaped magnetic pole (2) and (3), then on stator (1) and rotor (4), be wound with solenoid (6) and (7) respectively.When applying alternating voltage simultaneously or applying direct voltage simultaneously on these two groups of solenoids, so and the magnetic field of generation will make rotor (4) be attached on the corresponding a pair of side of two fan-shaped magnetic poles.If one group of solenoid is wherein applied rightabout voltage, then rotor (4) will promptly rotate an angle and be adsorbed to fan-shaped magnetic pole another on the side.To the voltage of transformation direction endlessly of one group of solenoid wherein, voltage direction of another group solenoid remains unchanged, and then rotor will constantly come and go rotation.The angle of each rotation all is changeless, can not produce the fault that the anglec of rotation changes.
When only using DC power supply, can be stator (1), one of them of rotor (4) or fan-shaped magnetic pole (2) and (3) used the permanent magnetic material manufacturing instead, and stator (1) and rotor (4) are only gone up like this needs around one group of solenoid.
In order to reduce " remanent magnetism " and because the magnetic flux density of rotor and stator differs the dead phenomenon of bigger caused suction, fixedly the non-magnet material of suitable thickness (8) non-magnet material (8) while is also played the restrict rotor anglec of rotation between fan-shaped magnetic pole and rotor.It can be fixed on the end face of fan-shaped magnetic pole and also can be fixed on the side of rotor.
If fan-shaped magnetic pole (2) and (3) are fixed on the two ends of rotor (4), can play magnetic conduction too and limit anglec of rotation effect.
The utility model has been realized having reduced cost by the translation function of the signal of telecommunication to the fixed angle mechanical location with simple mechanism, has reduced fault.
The utility model embodiment: rotor is made with the bar shaped permanent magnetic material.Be wound with one group of solenoid on the U-shaped stator, use 6 volts of DC power supply work.Rotor is done the spinning movement that comes and goes 90 degree.Embodiment is used in the pistol shooting simulation trainer.
Claims (4)
1, comes and goes the electric operator of rotation with fixed angle.Feature of the present utility model is: comprise U-shaped stator (1), two fan-shaped magnetic poles (2) and (3), non-magnet material (8) rotor (4) and rotating shaft (5).Rotor (4) and rotating shaft (5) are fixed together and can be by electromagnetic force round rotations in the angle that two fan-shaped magnetic poles (2) and (3) are limited.
2, according to the electric operator of claim 1, it is characterized in that: when rotor (4), U-shaped stator (1), fan-shaped magnetic pole (2) and (3) are when adopting ferrimagnet, then to be wound with solenoid (6) and (7) respectively on U-shaped stator (1) and the rotor (4).
3, according to the electric operator of claim 1, it is characterized in that: is one of them of rotor (4), U-shaped stator (1), fan-shaped magnetic pole (2) and (3) to adopt permanent magnetic material, and all the other are when adopting ferrimagnets, and then go up only need be around one group of solenoid for U-shaped stator (1) and rotor (4).
4, according to the electric operator of claim 1 or 2 or 3, its feature also is: non-magnet material (8) is fixed on the end face of the fan-shaped magnetic pole between fan-shaped magnetic pole and the rotor or on the side of rotor.
