Technical field
The utility model patent relates to a kind of vibrator, particularly a kind of endurance permanent magnetism vibrator.
Background technology
Vibrator be attached to some machinery and equipment in order to produce the device of exciting force, be the vitals that utilizes mechanical oscillation.Vibrator can make to be swashed object and obtain certain forms and big or small vibratory output, thereby object is vibrated and strength test, or vibration testing instrument and sensor are calibrated.Vibrator also can be used as driver unit and forms vibrating machine, in order to realize the work such as making firm by ramming of the conveying, screening of material or object, closely knit, moulding and soil sandstone.Vibrator can produce unidirectional or multidirectional, the exciting force of simple harmonic quantity or non-simple harmonic quantity.
The domestic research of magneto vibrator is since the eighties in 20th century.Mainly concentrate on ferrite as the research of permanent magnet.The volume of the permanent magnetism vibrator of prior art is larger; spring leaf is arranged on top or the bottom of vibration column; location, one end; use a period of time after vibration post movement locus to change; spring leaf and vibration column adopt fixing connected mode, and vibration resistance is excessive, and the heat of generation is more; reduced service life, spring leaf is fixedly connected with and causes spring leaf easily to damage with vibration column.
Summary of the invention
The purpose of this utility model is the deficiency existing for prior art, provides a kind of volume little, and vibration resistance is little, vibration column stability-of-path, producing heat few, spring is not fragile, the endurance permanent magnetism vibrator of long service life.
For achieving the above object, the technical scheme that the utility model endurance permanent magnetism vibrator adopts is:
A kind of endurance permanent magnetism vibrator, comprise outer cover, bottom at outer cover is provided with permanent magnet, described permanent magnet is provided with magnetic core, outer gap at magnetic core is socketed with vibration column, described vibration column reaches outer cover outside, in the bottom of vibration column and the arranged outside of magnetic core overlapping position, there is solenoid, outer side clearance at vibration column is socketed with the support fixing with outer cover, in the surrounding of support, be evenly equipped with the uprighting spring sheet of vertical setting, at the two ends of uprighting spring sheet, be connected with horizontal spring sheet, two-layer horizontal spring sheet and the bilevel step overlap joint that is arranged on vibration column outside.Spring leaf and vibration column overlap joint, reduced the resistance of spring leaf to vibration column, reduced the generation of heat, reduced the free degree restriction to spring leaf simultaneously, and one way is stressed respectively for bilevel horizontal spring sheet, the service life of having improved spring leaf; Two-layer horizontal spring sheet is separately positioned on the two ends of uprighting spring sheet, to vibration column, provides good guiding, has guaranteed that the movement locus of vibration column is steady, has improved the service life of vibrator, adopts permanent magnet to reduce the volume of vibrator.
Described uprighting spring sheet and horizontal spring sheet are layer structure, comprise the beryllium-bronze plate and the carbon fiber board that are bonded as one.Spring leaf is changed into the composite plate of beryllium-bronze plate and carbon fiber board by common epoxy plate, phosphorus copper plate, improved fatigue strength, has strengthened reliability, can effectively reduce and eliminate the resonance point that in operating frequency, reed causes.
Described permanent magnet is Nd-Fe-B permanent magnet.Neodymium iron boron is as rare earth permanent-magnetic material, the feature with high energy product, high-coercive force and high residual magnetization, coercivity is ferritic ten several times of common permanent magnet, the 3-5 of common rare-earth permanent magnet aluminium nickel cobalt doubly, can effectively improve magnetic gap magnetic field intensity, improve power efficiency, and can reduce vibrator size.
Described support inner side is provided with short-circuited conducting sleeve, this short-circuited conducting sleeve and vibration column matched in clearance.
The step in vibration column outside is boss, within bilevel boss is limited in two-layer spring leaf.
The utility model compared with prior art, has the following advantages:
Spring leaf and vibration column overlap joint, reduced the resistance of spring leaf to vibration column, reduced the generation of heat, reduced the free degree restriction to spring leaf simultaneously, and one way is stressed respectively for bilevel horizontal spring sheet, the service life of having improved spring leaf; Two-layer horizontal spring sheet is separately positioned on the both sides of uprighting spring sheet, to vibration column, provides good guiding, has guaranteed that the movement locus of vibration column is steady, has improved the service life of vibrator, adopts permanent magnet to reduce the volume of vibrator.Spring leaf is changed into the composite plate of beryllium-bronze plate and carbon fiber board by common epoxy plate, phosphorus copper plate, improved fatigue strength, has strengthened reliability, can effectively reduce and eliminate the resonance point that in operating frequency, reed causes.Neodymium iron boron is as rare earth permanent-magnetic material, the feature with high energy product, high-coercive force and high residual magnetization, coercivity is ferritic ten several times of common permanent magnet, the 3-5 of common rare-earth permanent magnet aluminium nickel cobalt doubly, can effectively improve magnetic gap magnetic field intensity, improve power efficiency, and can reduce vibrator size.
