Embodiment
Below in conjunction with accompanying drawing reciprocator of the present utility model is carried out concrete description.
Overall structure of the present utility model comprises support 1, guide rail 2, permanent magnet 3, slide block 4, roller 5 and the first solenoid 61, the second solenoid 62, three solenoid 63, the 4th solenoid 64 as shown in Figure 1 to Figure 3.
Wherein, the guide rail 2 of arc is that parallel two single tracks (2a, 2b) form, and from front view, guide rail 2 is semicircle.Arc is the some of the periphery just justified, preferential semicircle.
The first solenoid 61, the second solenoid 62, three solenoid 63 and the 4th solenoid 64 can be fixed between two single tracks (2a, 2b) by screw respectively, as depicted in figs. 1 and 2, the two stands 1 of guide rail 2 belows both supported guide rail 2, again the first solenoid 61, the second solenoid 62, three solenoid 63 are fixed connection with the 4th solenoid 64, and limit first to fourth solenoid and be positioned between two single tracks (2a, 2b).Wherein, the first solenoid 61 and the second solenoid 62 lay respectively at the bilateral symmetry position of the middle position of below, guide rail bottom, three solenoid 63 and the 4th solenoid 64 lay respectively at the top of the first solenoid 61 and the second solenoid 62, are positioned at the monosymmetric position of middle position with respect to below, guide rail 2 bottoms.
One of mode of magnetization of permanent magnet of the present utility model is axial magnetized, the parallel distribution of the magnetic induction line of permanent magnet internal magnetic field.
The another kind of mode of magnetization of the utility model permanent magnet, for magnetizing along the external magnetic field magnetic line of force, at this moment, the magnetic induction line of permanent magnet inside is divergent shape and distributes, and the direction of magnetization is the direction along the external magnetic field magnetic line of force.This mode of magnetization can be so that easier the generation with the external magnetic field of permanent magnet interacts.
After the solenoid energising, according to Ampere's law (also claiming right-hand screw rule), solenoid one end is geomagnetic into the N utmost point, and the other end is geomagnetic into the S utmost point, the analogy of magnetic field of its external magnetic field and bar magnet.Therefore, because the effect of energization solenoid surrounding magnetic field, according to the principle that homopolar-repulsion, heteropole are inhaled mutually, permanent magnet will be attracted or repel, so move along the arc-shaped rail generation.Below carry out concrete operating state explanation.
When first to fourth solenoid was not all switched on, the magnetic slide assemblies that is comprised of permanent magnet 3, slide block 4 and roller 5 was in the bottom centre place of arc-shaped rail, as depicted in figs. 1 and 2 under action of gravitation.
When 61 energising of the first solenoid, generate an electromagnetic field in its outside, the principle of inhaling mutually according to homopolar-repulsion, heteropole, under the effect of electromagnetic field, permanent magnet 3 is attracted, thereby drive whole magnetic slide assemblies along the direction of guide rail 2 to the first solenoid 61, the highest high order end place that is moveable to the first solenoid 61.
When 62 energising of the second solenoid, in like manner, permanent magnet 3 also can move to the direction of the second solenoid 62 along guide rail 2, the highest low order end place that is moveable to the second solenoid 62.
It is pointed out that the electromagnetic field that can produce different directions and varying strength by regulating solenoidal "on" position, thereby permanent magnet is produced the effect that attracts or repel, permanent magnet drives whole magnetic slide assemblies and moves back and forth along guide rail.The cooperation of the direction of solenoidal wire canoe and impressed current, should make the magnetic slide assemblies during in the energising of the first solenoid 61 or the direction of motion during 62 energising of the second solenoid be opposite.
If the first solenoid 61 and the second solenoid 62 be staggered energising continuously, the magnetic slide assemblies that is comprised of permanent magnet 3, slide block 4 and roller 5 can move back and forth along guide rail 2 between the low order end of the high order end of the first solenoid 61 and the second solenoid 62.
When the first solenoid 61 and three solenoid 63 are switched on simultaneously, all generate an electromagnetic field in its outside, then permanent magnet 3 can be under the effect of this electromagnetic field successively to the direction motion of the first solenoid 61 left ends, three solenoid 63 left ends, and drive the motion of whole magnetic slide assemblies, the highest high order end place that is moveable to three solenoid 63 of this slide assemblies.
In like manner, if the second solenoid 62 and the 4th solenoid 64 are switched on simultaneously, the magnetic slide assemblies is moveable to the low order end of the 4th solenoid 64 successively to the direction motion of the second solenoid 62 right-hand members, the 4th solenoid 64 right-hand members.
It is pointed out that the cooperation of the direction of solenoidal wire canoe and impressed current herein, should make at the magnetic slide assemblies during in 63 energising of the first solenoid 61 and three solenoid that the direction of motion of magnetic slide assemblies is identical; When the second solenoid 62 and the energising of the 4th solenoid 64, the direction of motion of magnetic slide assemblies is identical, but the direction of motion of the magnetic slide assemblies of this motion when switching on the first solenoid 61 and three solenoid 63 is opposite.
When the first solenoid 61 and three solenoid 63 are switched on simultaneously, the second solenoid 62 and the 4th solenoid 64 are switched on simultaneously, and the first solenoid 61 and three solenoid 63 and the second solenoid 62 and the 4th solenoid 64 be continuously during staggered energising, and the magnetic slide assemblies can move back and forth between the low order end of the high order end of three solenoid 63 and the 4th solenoid 64.
If need to allow the slide assemblies stop motion, then need the first solenoid 61, the second solenoid 62, three solenoid 63 and the 4th solenoid 64 are all cut off the power supply, like this, under action of gravitation, the magnetic slide assemblies will slide into along guide rail 2 the bottom center position of guide rail 2, i.e. reset condition before the energising.Simultaneously, in order to prevent the back and forth generation of concussion, need the first solenoid 61 and three solenoid 63, perhaps the second solenoid 62 and the 4th solenoid 64 input reverse currents.The solenoid that passes into reverse current can produce rightabout magnetic field when working, thereby effectively stoped the reciprocal concussion of magnetic slide assemblies, make the quickly stop motion of magnetic slide assemblies, and finally stop at the middle position of guide rail bottom, whole device quits work.
Above-mentioned structure and working method make reciprocator of the present utility model can realize directly driving controlled device is carried out reciprocally swinging in limited angular range function, and do not need the mode that adopts traditional electric rotary machine to be combined with machinery or electronics transmission mechanism, thereby simple in structure, have higher reliability and higher efficient and control precision.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
