Description
Technical field
The utility model is the permanent-magnet manipulating mechanism of quick straight reciprocating motion, can be used on the quick straight reciprocating motion apparatus operating of needs.
Background technology
The mechanism that is used in straight reciprocating motion often adopts toggle etc. rotation to be converted into the mode of translation.The patent No. is that 90106697.4 patent " line reciprocator " has been carried out new design with regard to the mode of rotating translation, but adopts the mode that is converted into translation, and not only energy transmission efficiency is low, and mechanism's complexity, easily damage.Linear electric motors are methods of existing a kind of straight reciprocating motion.The patent No. is that the patent " electromagnet type linear electric motors " of 200410046893.x adopts many group coils, but uses relatively too complexity, and it is not high to exert oneself.
Summary of the invention
Technical problem: the utility model purpose is to overcome the shortcoming of prior art, and a kind of quick linear permanent-magnet operating mechanism is provided, and realizes straight reciprocating motion by utilizing two groups of coil alternate energisations.By utilizing the repulsion between the permanent magnetism to realize buffering, limit the collision of sound iron core simultaneously.
Technical scheme: a kind of quick linear permanent-magnet operating mechanism of the present utility model comprises connecting rod, fixed core, first coil, second coil, the moving iron core of permanent magnet, the first buffering permanent magnet and the second buffering permanent magnet; Connecting rod is positioned in the middle of the fixed core, and the first buffering permanent magnet and the second buffering permanent magnet lay respectively at the two ends up and down at middle part in the fixed core, and the moving iron core of permanent magnet is positioned at the middle part of fixed core and is fixed on the connecting rod, and first coil and second coil stationary are in fixed core.
The first buffering permanent magnet is identical with the second buffering permanent magnet polarity, and it is all opposite with the moving polarity unshakable in one's determination of permanent magnet, during the coil no power, because the suction between moving iron core of the repulsion effect of permanent magnetism and permanent magnet and fixed core, the moving iron core of permanent magnet is in the equilbrium position at the middle pole shoe of fixed core position.
Connecting rod is a non-magnet material, and passes the preformed hole in the middle of fixed core, permanent magnet and the permanent magnet, and fixed core is a permeability magnetic material.
Permanent magnet is moving unshakable in one's determination by the first moving permanent magnet unshakable in one's determination, armature and the second permanent magnet replacement moving unshakable in one's determination, and armature is permeability magnetic material.The first moving permanent magnet unshakable in one's determination is identical with the second moving permanent magnet polarity unshakable in one's determination, and all opposite with the second buffering permanent magnet polarity with the first buffering permanent magnet.
When coil did not have applied voltage, owing to the repulsion effect of permanent magnet on the fixed core and the suction of moving iron core of permanent magnet and pole shoe, the moving iron core of permanent magnet was in the equilbrium position; During work, control circuit gives first coil logical positive current earlier, and the moving iron core of permanent magnet is subjected to downward thrust, moves downward; Turn-off first coil then, give second coil logical positive electricity, the moving iron core of permanent magnet is subjected to thrust upwards, through oppositely accelerated motion after the moderating process; When the moving iron core of permanent magnet is got back to the equilbrium position, turn-off second coil, give first coil logical positive current; So straight reciprocating motion.
In motion process, because the repulsion effect of permanent magnet on the fixed core, it is far away more that the moving iron core of permanent magnet departs from the equilbrium position, and the permanent magnet expulsive force that is subjected to cushioning permanent magnet is big more, is in the reciprocating motion at center thereby iron core is remained on the equilbrium position.When moving iron core passes the equilbrium position, make coil realize break-make alternately, reciprocating motion remains.
Beneficial effect: switching coil electric current when the equilbrium position, moving unshakable in one's determination stressed big, for moving reciprocating motion unshakable in one's determination provides enough energy; Since permanent magnet moving unshakable in one's determination with the buffering permanent magnet near the time, it is big that permanent magnet expulsive force becomes, and cuts down the trend of sound contact unshakable in one's determination rapidly; The tooth mouth can increase the stability in the moving motion process unshakable in one's determination on the pole shoe.
