Description
Technical field
The present invention relates to a kind of big load mechanical type angle vibration table, belong to the vibration detection technology field, be specially adapted to high precision photoelectric equipment, especially the lasting accuracy of airborne photoelectric equipment detects.
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 characteristics such as wide frequency range.But its load capacity is less, and the maximum load amount has only more than ten kilogram usually, is used for the performance test of inertia device is detected with calibration more.High precision photoelectric equipment, the especially lasting accuracy of airborne photoelectric equipment detect and to need angle vibration table to provide angular oscillation for it, but its volume, weight are bigger, and dozens or even hundreds of kilogram is often all arranged, and therefore, need have the angle vibration table of bigger load.
Summary of the invention
The objective 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, direction is opposite, frequency is identical bigger exciting force when avoiding motor, can realize the angular oscillation under the big load, big load mechanical type angle vibration table simple in structure the direct driving of table top main shaft, work.
Technical scheme of the present invention is:
A kind of big load mechanical type angle 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 to encourage 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 big belt wheel, and the belt wheel on the inertia vibration generator is a small pulley.
Big 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 are with synchronous pulley and be with driving coupling synchronously, are used to make the rotation axis of two inertia vibration generators to rotate with same rotational speed, opposite phase.
A stretching pulley in the middle of being with synchronously, two inertia vibration generators of the present invention is arranged.
Inertia vibration generator of the present invention is an 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 bigger exciting force.
Make both eccentric directions opposite when 2, two inertia vibration generators are installed, and, can guarantee that rotating speed is identical, phase place is opposite, produce a pair of equal and opposite in direction, direction is opposite, frequency is identical exciting force during work by band transmission synchronously.
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 big.
