Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
As shown in Figure 1, Figure 2 and Figure 3, in one embodiment, a kind of Non-contact motion mode conversion device, comprises housing 110, motor 120, magnetic rotation whirlpool assembly 130 and driven element 140.Motor 120 is installed in housing 110, and housing 110 comprises fore shell 110a and back cover 110b.
Housing 110 has accepting groove 112, and driven element 140 is installed on also can to-and-fro motion in accepting groove 112 in accepting groove 112.In the present embodiment, housing 110 also has motor base station 114 and two slots 116.The two ends of motor base station 114 are inserted in two slots 116, and the main shaft of motor 120 is through motor base station, and the shell of motor 120 is installed on motor 120 base station.
Magnetic rotation whirlpool assembly 130 has opposite polarity two magnetic faces 1322,1342 toward the outer side.In the particular embodiment, magnetic rotation whirlpool assembly 130 comprises the first magnet 132, second magnet 134 and magnet holder 136.First magnet 132 and the second magnet 134 have opposite polarity two magnetic faces 1322,1342.Usually, the first magnet 132 and the second magnet 134 are magnetite, magnet or electromagnet.Magnet holder 136 has two draw-in grooves 1362,1364, first magnet 132 and the second magnet 134 and to be arranged in two draw-in grooves 1362,1364 respectively, and makes opposite polarity two magnetic faces 1322,1342 exposed and opposing.Magnet holder 136 also has axis hole 1366, and the main shaft interference fit of axis hole 1366 and motor 120, opposite polarity two magnetic faces 1322,1342 are parallel to the shaft axis of axis hole 1366 respectively.Be understood that, in other embodiments, the shaft axis of opposite polarity two magnetic faces 1322,1342 and axis hole 1366 also can respectively in certain angle.Can also be the shaft axis that one of them magnetic face is parallel to axis hole 1366, the shaft axis of another magnetic face and axis hole 1366 be an angle.
Driven element 140 has identical two the magnetic faces 1422,1442 of polarity, and two magnetic faces 1422,1442 non-contact that polarity is identical is oppositely arranged.In the present embodiment, driven element 140 has the 3rd magnet 142, the 4th magnet 144 and two driving arms 146,148.3rd magnet 142 and the 4th magnet 144 have identical two the magnetic faces 1422,1442 of polarity, 3rd magnet 142 and the 4th magnet 144 are arranged on two driving arms 146,148 relative two sides respectively, and make polarity identical two magnetic faces 1422,1442 relative.Usually, the 3rd magnet 142 and the 4th magnet 144 are respectively magnetite, magnet or electromagnet.
Magnetic rotation whirlpool assembly 130 is connected with the main shaft of motor 120, and extends in the region between identical two the magnetic faces 1422,1442 of polarity, when magnetic rotation whirlpool assembly 130 rotates with the main shaft of motor 120, drives driven element 140 to-and-fro motion in accepting groove 112.
Be described below in conjunction with instantiation, if opposite polarity two magnetic faces 1322 on magnetic rotation whirlpool assembly 130, the polarity of 1342 is respectively N pole and S pole, be set to assembly N pole and assembly S pole, driven element 140 has two identical magnetic faces 1422 of polarity, the polarity of 1442 is N pole, be respectively a N pole and the 2nd N pole, magnetic rotation whirlpool assembly 130 with motor 120 main shaft rotate time, assembly N pole and assembly S pole are along with rotation, in assembly N pole in a N pole approach process, promote the lateral movement of driven element 140 to a N pole gradually, when assembly N pole is in the 2nd N pole approach process, promote the lateral movement of driven element 140 to the 2nd N pole gradually, the rotation of assembly N property polar period, thus drive driven element to complete to-and-fro motion.In like manner, in assembly S pole in a N pole approach process, attract driven element 140 to a lateral movement of the 2nd N pole gradually, when assembly N pole is in the 2nd N pole approach process, attract driven element 140 to a lateral movement of a N pole gradually, the rotation of assembly N property polar period, thus attract driven element to complete to-and-fro motion.When assembly N pole and assembly S is extremely opposing arrange time, assembly N pole produces while repulsive force, and assembly S pole produces attraction force, increases driven element 140 unidirectional stressed, contributes to the to-and-fro motion of driven element 140.In like manner known, when two magnetic face polarity of driven element 140 are S pole, the to-and-fro motion of driven element 140 can be realized equally.
In a word, magnetic pole has the two poles of the earth, be respectively N pole and S pole, therefore, magnetic rotation whirlpool assembly 130 only there is a magnetic face identical or contrary with the polarity in two magnetic faces of driven element 140, magnetic rotation whirlpool assembly 130 with motor 120 main shaft rotate time, opposite polarity two magnetic faces 1322,1342 are along with rotation, when magnetic identical with two magnetic face polarity of driven element 140 on magnetic rotation whirlpool assembly 130 can produce repulsive interaction in one of them magnetic face approach process of driven element 140, thus promote the lateral movement of driven element 140 to this magnetic face; When magnetic identical with two magnetic face polarity of driven element 140 on magnetic rotation whirlpool assembly 130 can produce repulsive interaction in another magnetic face approach process of driven element 140, thus promote the lateral movement of driven element 140 to this another magnetic face, vortex assembly 130 Periodic Rotating, thus make driven element 140 to-and-fro motion in accepting groove 112.In addition, when magnetic rotation whirlpool assembly polarity 130 contrary two magnetic faces 1322,1342 opposing arrange time, when magnetic identical with two magnetic face polarity of driven element 140 on magnetic rotation whirlpool assembly 130 produces repulsive interaction in the face of one of them magnetic face of driven element 140, another magnetic on magnetic rotation whirlpool assembly 130 produces sucking action in the face of another magnetic face of driven element 140, thus it is unidirectional stressed to increase driven element 140, contributes to the to-and-fro motion of driven element 140.
Above-mentioned Non-contact motion mode conversion device, rely on magnetic force to complete the conversion that rotary motion forwards straight reciprocating motion to, mechanical connects, vibrate more weak, noise is less, the wearing and tearing that mechanical connects and high-precision processing request, structure is comparatively simple, easy processing.
The above embodiment only have expressed several mode of execution of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
