In above-mentioned technical proposal, the longitudinal cross-section product of second sliding block 430 is accumulated more than the longitudinal cross-section of third sliding block 347
And accumulated less than the longitudinal cross-section of the first sliding block 330, when the first sliding block is driven to be individually moved, the hydraulic liquid of per stroke change
Product is maximum；When second sliding block moves, the hydraulic oil volume that per stroke changes is taken second place；It is single when driving third sliding block is individually moved
The hydraulic oil volume of position stroke alteration is minimum；Namely when driving the first sliding block Moving Unit stroke, the movement of the second sliding block
Distance is more than unit displacement distance, and when driving third sliding block that per stroke is individually moved, the displacement distance of the second sliding block is less than
Unit displacement distance.
In the present invention, third sliding block is individually moved to be finely adjusted for the hydraulic pressure oil capacity to the second guide rail interior, also
It is that the position of the second sliding block is finely adjusted, therefore third sliding block individually serves as the effect of an inching switch, passes through hydraulic oil
Volume carry out the fine tuning of position, adjust step pitch smaller, adjustment distance more controllable precise.First sliding block is used to lead to second
Hydraulic pressure oil capacity inside rail carries out homophony, that is, carries out homophony, therefore the first sliding block integrally fills to the position of the second sliding block
When the effect of a homophony switch, the adjusting of position is carried out by the volume of hydraulic oil, it is rapider to adjust process.
Change the position and movement distance of slide unit, realize the scanning imagery to target object, specifically, controller control connection
Moving axis is engaged with the first screw, and the first sliding block shift motion is controlled by rotary drive mechanism, you can the shifting of the second sliding block of control
Dynamic stroke, the first sliding block play the second slide position homophony, when universal driving shaft is controlled to be engaged with the second screw, pass through and rotate driving
Mechanism controls third sliding block shift motion, you can the shift motion of the second sliding block of control, third sliding block individual play slide unit position
Fine tuning effect, the first sliding block plays the role of the homophony of position, by the shift motion of the first sliding block of control, the second sliding block is fast
Speed is moved near target location, and then by individually controlling the shift motion of third sliding block, the second sliding block accurate movement is arrived
Target location, the position for accelerating slide unit are regulated the speed, while improve the mobile accuracy of slide unit, and then improve scanning device
Quality of scanning.
Meanwhile the shift position of the second sliding block and displacement distance are fed back by straight-line displacement ball bar, for feedback control
The movement of first sliding block and third sliding block.Accumulative operation, unavoidably will appear position deviation, once when the position of the second sliding block
And when deviation occurs in goal-setting position, for example the position of the second sliding block does not reach target location also, at this point, controller calculates the
The offset distance of two sliding blocks, because the longitudinal cross-section in first and second guide rail and accommodating cavity inside space product is certain, you can calculate
The deviation volume of the hydraulic oil in the second guide rail interior space, the first sliding block of controller or control third sliding block single movement, adjustment
The The hydraulic oil in the second guide rail interior space, after the hydraulic oil in the second guide rail interior space obtains the hydraulic oil of deviation volume, i.e.,
The target location that the linkage slide unit arrival of the second sliding block can be driven to specify, so as to eliminate offset deviation in time, improves the scanning of equipment
Precision.
In order to verify the effect of platform of the present invention, using 5mW lasers as testing tool, 5mW lasers are arranged on slide unit,
Test stability during system operation, jitter conditions when slide unit is run.Record the setting range ability and reality when slide unit is run
Border range ability tests the accuracy of system.Finally, system output waveform is tested, this pulse will be sent to subsequent spoke
Meter measuring system is penetrated, as its standby signal, analyzes its accuracy.
Test proves that the shake of slide unit during system operation is all very small, and the shake of vertical direction is than horizontal direction
It is also much smaller, illustrate to absorb by hydraulic system, shake very little caused by motor operation, system is very stable.Meanwhile system
The setting position of operation and the error of physical location are almost without it can be seen that system operation accuracy is very high.
From the above mentioned, the present invention is slided under the premise of a rotary drive mechanism is only used by homophony sliding block and fine tuning
Block is used cooperatively, and improves the mobile accuracy of slide unit, and it is simple to operate, stability is good；Meanwhile the present invention has precision
High, simple to operate, the features such as stability is good, safe, necessary platform base is provided for industrial production and research；
By homophony and vernier control, slide unit moving process of the invention more accurately and quickly, and eliminates the shake of slide unit.
Although the embodiments of the present invention have been disclosed as above, but its be not restricted in specification and embodiment it is listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easy
Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, it is of the invention and unlimited
