Abstract
The utility model relates to a magnetic shock absorber which comprises a cylindrical shock-absorption upper shell and a disc-shaped shock-absorption lower baseboard, wherein an upper magnet is arranged in the shock-absorption upper shell and a lower magnet is arranged on the shock-absorption lower baseboard; the upper magnet and the lower magnet are arranged in a way that the same pole is opposite to each other; a clearance which is formed by the repulsive force between the upper and lower magnets and can change along with the change of the load or the vibration in the thickness is arranged between the upper magnet and the lower magnet; at least one pair of guide pillars is arranged on the shock-absorption lower baseboard; and the heights of the guide pillars are lower than the height of the upper shell. The shock absorption function of the magnetic shock absorber is bidirectional, so that the vibration interference from the ground to instruments are reduced and the vibration caused by self-vibrating equipment to the ground and the periphery is reduced and any energy is consumed; and the magnetic shock absorber is simple and compact in structure, convenient for mounting and free of routine maintenance and adjustment.
Description
Technical field
The utility model relates to a kind of vibration damper, more specifically says so into reducing extraneous vibration to precision instrument and equipment, as the magnetic vibration reducing device of interference such as electron microscope, optical precision measurement.
Background technique
At aspects such as various industrial technologies application and precision measuremnts, be influence and the interference of avoiding shaking, need to use various technological means, specifically just be to use the vibration damper of various principles.Vibration damper can be divided into active and passive type two big classes according to working principle.The passive type vibration damper just utilizes the physical property of isolated material to reduce vibrations, current existing rubber type, spring, the steam cushion formula etc. of mainly containing.Because the intrinsic physical property of material and structure is limit, existing passive type vibration damper is unsatisfactory in the face of the low-frequency vibration effect of tens of Hz.Disturb particularly owing to the resonant frequency that is difficult to reduce them, thereby for the vibrations below the 20Hz, do not have damping effect substantially.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of not only can the minimizing and shakes interference more than the 20Hz, and can effectively reduce the magnetic vibration reducing device that the following low-frequency vibration of 20Hz disturbs.
The technological scheme that realizes the utility model purpose is as follows:
A kind of magnetic vibration reducing device, comprise cylindrical shape damping upper shell, disc damping lower shoe, be provided with upper magnet in the damping upper shell, the damping lower shoe is provided with lower magnet, upper magnet and lower magnet are that the same sex is oppositely arranged, and between upper magnet and the lower magnet, are formed with the gap that thickness changes with the variation of loading or vibrate by the repulsive force between magnet, at least be provided with a pair of guide pillar on the described damping lower shoe, the height of guide pillar is less than the height of upper shell.
Described damping lower shoe is provided with three guide pillars, and three guide pillars are evenly distributed in the upper-end surface of damping lower shoe.
Described damping lower shoe is provided with four guide pillars, and four guide pillars are evenly distributed in the upper-end surface of damping lower shoe.
All offer mounting groove on described damping upper shell, the damping lower shoe, upper magnet, lower magnet are separately positioned in separately the mounting groove.Upper magnet, lower magnet can be each defined in like this in the mounting groove on damping upper shell, the damping lower shoe, guarantee that upper magnet, lower magnet can not be displaced to other positions, and influence damping effect.
Described upper magnet and lower magnet are samarium-cobalt magnet.
Adopt such scheme, be provided with a pair of guide pillar on the damping lower shoe at least, the height of guide pillar is less than the height of upper shell.When vibration damper was worked, guide pillar can make the damping upper shell move fully longitudinally with respect to the damping lower shoe, can not make owing to the principle of magnetic force the damping upper shell left or right avertence move, the shock-absorbing function of vibration damper is given full play to.Cushioning effect of the present utility model is two-way, both can be with reducing in the face of the vibration interference of instrument and equipment, also can reduce vibrations are arranged self equipment to ground and vibrations on every side, do not consume any energy in addition, it is simple and compact for structure, and is easy for installation, does not need regular maintenance and adjustment.
