Abstract
An electromagnetic vibrator comprises a vibrating table and a base disposed sequentially from top to bottom. Springs are symmetrically supported between the vibrating table and the base. An electromagnet is embedded in the base. The upper end face of the vibrating table is provided with a moving contact electrically connected to one pole of the electromagnet. A fixed contact electrically connected with the other pole of the electromagnet is further disposed right above the moving contact. The electromagnet comprises an electromagnetic coil and an electromagnetic core disposed in the center of the electromagnetic coil. An anode of the electromagnetic coil is electrically connected with the moving contact through an anode binding post on one side of the base. A cathode of the electromagnetic coil is sequentially and electrically connected with a direct-current power source and the fixed contact through a cathode binding post on one side of the base. The fixed contact is fixed on the base through a troughed support and screws. Compared with the prior art, the electromagnetic vibrator has the advantages that through the use of the electromagnet and the moving and fixed contacts, the structure is simplified and processing is easy; vibrational amplitude and frequency are convenient to adjust; the electromagnetic vibrator is low in noise and economical and durable.
Description
Technical field
The present invention relates to a kind of vibrator, relate in particular to a kind of vibrator that utilizes Electromagnetic Drive.
Background technology
The vibrational structure of existing a lot of mechanical devices, adopt mechanical eccentric mechanism to realize vibration mostly, such mode of vibration, and improper complex structure, processing inconvenience, and also often noise is large in use, and energy consumption is high, and fault rate is high, and service life is short.
Summary of the invention
For above-mentioned technological deficiency, technical problem to be solved by this invention is to provide a kind of simple in structure, easy to operate, little durable vibrator of noise.
In order to solve the problems of the technologies described above, the present invention takes following technical scheme:
A kind of electromagnetic vibrator, comprise the shock platforms and the pedestal that from top to bottom set gradually, support and be provided with spring symmetrically between described shock platforms and pedestal, be embedded with electromagnet in described pedestal, described shock platforms upper surface is provided with the moving contact be electrically connected to a utmost point of electromagnet, also is provided with the static contact be electrically connected to another utmost point of electromagnet directly over this moving contact.
Further, described electromagnet comprises solenoid and is arranged at the middle electromagnetic core of solenoid.
Further, the positive pole of described solenoid is electrically connected to moving contact by the positive terminal that is arranged on pedestal one side, and the negative pole of solenoid is electrically connected to dc source, static contact successively by the negative terminal that is arranged on pedestal one side.
Further, described static contact is fixed on pedestal by Troffer and screw.
Further, between described static contact and support, between moving contact and shaking platform, be provided with the insulation interlayer.
The present invention compared with prior art, by electromagnet and dynamic/static contact are set, simplifies the structure, and is easy to processing, is convenient to adjusting amplitude and frequency, and noise is little, economy and durability.
The accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
The specific embodiment
For the ease of those skilled in the art's understanding, below in conjunction with accompanying drawing, the invention will be further described.
A kind of electromagnetic vibrator as shown in Figure 1, comprise the shock platforms 1 and the pedestal 3 that from top to bottom set gradually, support and be provided with spring 2 symmetrically between described shock platforms 1 and pedestal 3, be embedded with electromagnet in described pedestal 3, described shock platforms 1 upper surface is provided with the moving contact 13 be electrically connected to a utmost point of electromagnet, also is provided with the static contact 12 be electrically connected to another utmost point of electromagnet directly over this moving contact 13.
Described electromagnet comprises solenoid 4 and is arranged at the middle electromagnetic core 15 of solenoid.
The positive pole of described solenoid 4 is electrically connected to moving contact by the positive terminal 6 that is arranged on pedestal 3 one sides, and the negative pole of solenoid 4 is electrically connected to dc source 7, static contact 12 successively by the negative terminal 5 that is arranged on pedestal 3 one sides.
Described static contact 12 is fixed on pedestal 3 by Troffer 9 and screw 8.
Between described static contact 12 and support 9, be provided with insulation interlayer 11 between moving contact 13 and shaking platform 1.
The operation principle of this shaking platform is as follows: shaking platform 1 moves upward under the effect of spring, thereby driving moving contact 13 moves upward, when moving contact 13 moves to while contacting with static contact 12, form power supply 7 by electric wire 10, static contact 12, moving contact 13, positive terminal 6, solenoid 4, negative terminal 5, the power circuit of power supply 7, solenoid 4 is switched on and is made electromagnetic core 15 produce magnetic, the elastic force that causes shaking platform 1 to overcome spring moves downward and attempts and draws close to pedestal 3 directions, when shock platforms 1 continues to move downward, the moving contact 13 be fixedly installed on shaking platform 1 is separated with the static contact 12 be fixed on pedestal 3, make described energising return to disconnect, solenoid 4 outages, electromagnetic core 15 loses magnetism, then lose the attraction to shaking platform 1, now shaking platform 1 is under the effect of spring 2, move upward, when moving to certain position, moving contact 13 contacts with static contact 12, make the power circuit conducting, thereby the continuation aforementioned activities of going round and beginning again, realize vibration.
Above-described embodiment of the present invention, do not form limiting the scope of the present invention.Any modification of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included in claim protection domain of the present invention.
