Background technology
Present angle vibration table mainly is the electric angle vibrative table that adopts motor direct-drive table top main shaft, and that this shaking table has is simple in structure, control accuracy is high and the characteristics such as wide frequency range.But its load capacity is less, and the maximum load amount only has more than ten kilogram usually, and is multiplex in performance test and calibration detection to inertia device.The lasting accuracy of high precision photoelectric equipment, especially airborne opto-electronic device detects needs angle vibration table to provide angular oscillation for it, but its volume, weight are larger, and dozens or even hundreds of kilogram is often arranged, and therefore, need to have the angle vibration table of larger load.
Summary of the invention
The object of the invention is to, overcome the shortcoming of prior art, provide a kind of and produce a pair of equal and opposite in direction, opposite direction, larger exciting force that frequency is identical when avoiding motor to the direct driving of table top main shaft, work, can realize the angular oscillation under the large load, large load mechanical angular vibration table simple in structure.
Technical scheme of the present invention is:
A kind of large load mechanical angular vibration table, it comprises stand, table top, frequency control motor and inertia vibration generator; The place is equipped with bearing seat in the middle of the described stand top, and the table top middle part connects with the table top main shaft with bearing seat; The stand both upper ends thereof is equipped with spring-damper, and the table top two ends are supported by spring-damper: the table top bottom is equipped with two inertia vibration generators by table top main shaft both sides; Frequency control motor is positioned at inertia vibration generator below, be installed on the stand, with the inertia vibration generator driving coupling, be used for excitation table top generation angular oscillation.
Two inertia vibration generator symmetries of the present invention are installed on the table top main shaft both sides of table top.
Frequency control motor of the present invention and inertia vibration generator driving coupling are the band driving coupling; Belt wheel on the frequency control motor is large belt wheel, and the belt wheel on the inertia vibration generator is small pulley.
Large belt wheel on the frequency control motor of the present invention and the small pulley on the inertia vibration generator are the V belt wheel, and driving-belt is the V band.
Two inertia vibration generators of the present invention connect with synchronous pulley and toothed belt transmission, are used for making the rotation axis of two inertia vibration generators to rotate with same rotational speed, opposite phase.
In the middle of two inertia vibration generator Timing Belts of the present invention a stretching pulley is arranged.
Inertia vibration generator of the present invention is eccentric block formula vibrator, or box vibrator, or the centrifugal vibrator of crosshead shoe.
Spring-damper of the present invention is the spring-damper of metal dry friction formula or rubber type or fluid pressure type.
Obvious technical effects of the present invention:
1, motor need not directly to drive the main shaft of table top, but by driving inertia vibration generator, its inner eccentric block is rotated, and produces centrifugal force, has avoided the high speed rotating of motor, thereby can produce larger exciting force.
Make both eccentric directions opposite when 2, two inertia vibration generators are installed, and by toothed belt transmission, can guarantee identical, the single spin-echo of rotating speed, produce a pair of equal and opposite in direction, opposite direction, exciting force that frequency is identical during work.
3, owing to the main shaft both sides that are installed on table top of two inertia vibration generator symmetries, the exciting force application point equates that to the distance of table top main shaft the exciting force of its generation has formed the moment of cosine rule, acts on table top, produces angular oscillation thereby drive table top.
4, the present invention is simple in structure, load is large.
