Processing unit 1 is delivered to, and the image that can be shown is formed by the processing of processing unit 1, it is this area routine techniques, therefore this implementation
Example is not described in detail.
As shown in Figure 2, Figure 4 shows, illumination adjustments component 4 include regulation pedestal 41, first hydraulic cylinder 42, second hydraulic cylinder 43,
Hydraulic pipe 44, regulation screw mandrel 45 and adjusting nut 46；The first hydraulic cylinder 42 is embedded in the bottom of the second storage tank 212
And its tailpiece of the piston rod is connected with the LED cold light sources 23, the second hydraulic cylinder 43 is embedded in the adjusting cavity 411 of regulation pedestal 41
Interior, the adjusting nut 46 is built in the adjusting cavity 411 and is connected with the piston end of the second hydraulic cylinder 43, the regulation
Screw mandrel 45 is rotatably connected with regulation pedestal 41 and one end is extended in adjusting cavity 411 and is connected with the screw thread of adjusting nut 46
Connect, the hydraulic pipe 44 is built in connection pipe body 31 and its both ends cylinder with first hydraulic cylinder 42 and second hydraulic cylinder 43 respectively
Body connects.It is specific when setting, because the second storage tank 212 is arranged to two, then first hydraulic cylinder 42, second hydraulic cylinder 43, liquid
It is two to press conduit 44, regulation screw mandrel 45 and adjusting nut 46, and corresponds and set with the second storage tank 212.Wherein,
One hydraulic cylinder 42 is coaxially disposed with the second storage tank 212, is easy to the piston rod of first hydraulic cylinder 42 axial along the second storage tank 212
Move and drive LED cold light sources 23 to be axially moved along the second storage tank 212；And second hydraulic cylinder 43 is set with the regulation dislocation of screw mandrel 45
Put, and the piston rod of second hydraulic cylinder 43, along the axially arranged of regulation screw mandrel 45, the piston end of second hydraulic cylinder 43 can adjusted
It is axially moved when screw mandrel 45 rotates in the presence of adjusting nut 46 along regulation screw mandrel 45；And hydraulic pipe 44 then connects the first liquid
Cylinder pressure 42 and second hydraulic cylinder 43, when adjusting screw rod rotates forward, adjusting nut 46 drives the piston end of second hydraulic cylinder 43
Motion upwards, negative pressure being formed in second hydraulic cylinder 43, then hydraulic oil enters second hydraulic cylinder 43 by first hydraulic cylinder 42, then and first
Negative pressure is formed in hydraulic cylinder 42, the tailpiece of the piston rod of first hydraulic cylinder 42 moves to away from the direction of illuminating lens 22, and it can drive LED
Away from illuminating lens 22, and when regulation screw mandrel 45 rotates backward, the piston end of second hydraulic cylinder 43 moves downward cold light source 23,
Then the piston end of corresponding first hydraulic cylinder 42 moves to the direction close to illuminating lens 22, and it can drive LED cold light sources 23 to lean on
Near lightning lens 22, its can by adjust between the rotation adjustment control LED cold light sources 23 of screw mandrel 45 and illuminating lens 22 away from
From, and coordinated by adjusting the screw thread between screw mandrel 45 and adjusting nut 46, it can ensure the precision of regulation.
In practical application, in order to ensure the precision of adjustment control, it is described for driving that illumination adjustments component 4 also includes one
The stepper motor 47 and one that low bar rotates is used for the impulse generator 48 that Driving Stepping Motor 47 rotates the setting number of turns, and it can pass through
Impulse generator 48 controls the number of turns that the quantity control stepper motor 47 for sending pulse rotates, and then controls to adjust nut about 46
For the distance of motion to control the distance that LED cold light sources 23 move, it can ensure the precision of control.
The present embodiment illumination adjustments component 4 also includes a guide cylinder 49 mutually agreed with the inwall of the second storage tank 212,
The guide cylinder 49 is connected with the side walls of the second storage tank 212, and the LED cold light sources 23 are built in guide cylinder 49, is led to
Cross and set a guide cylinder 49 to ensure that LED cold light sources 23 are axially moved along the second storage tank 212, avoid it that radial wobble occurs,
It ensure that the accuracy of light regulation.Meanwhile the side wall of the second storage tank 212 be provided with it is at least one along its axial arranged guide groove
212a, the outer surface of guide cylinder 49 set the sliver 491 agreed with guide groove 212a phases, when specifically setting, guide groove 212a and sliver 491
Two are disposed as, it can avoid guide cylinder 49 that circumferential movement occurs with respect to the second storage tank 212, and it advantageously ensures that LED is cold
The stability that light source 23 moves.
As shown in Fig. 2, Fig. 5, Fig. 6, and in order to ensure that it is coaxial that the piston rod of first hydraulic cylinder 42 and guide cylinder 49 move
Property, a U-bracket 40 can be set, the U-bracket 40 includes a connection piece 401 and prolonged from the free end of connector 401 to its side
Two support members 402 to be formed are stretched, the free end of the support member 402 is connected to the outer rim of guide cylinder 49, first hydraulic cylinder 42
Piston rod is connected to the middle part of the connector 401, and the length of connector 401 can be set and the internal diameter phase of the second storage tank 212
Together, corresponding support member 402 is arranged to what is mutually agreed with the inwall of the second storage tank 212 with respect to the inwall side of the second storage tank 212
Arc, it advantageously ensures that U-bracket 40 is axially moved along the second storage tank 212, ensures the precision that guide cylinder 49 is axially moved.
Image adjustment component 5, it is essentially identical with the control principle of illumination adjustments component 4, and it is mainly used in described in regulation
The distance between ccd sensor 25 and object lens 24, it is advantageous to focus.Because the internal face of cavity to be seen senses with respect to CCD
Device 25 is inclined, and it is unintelligible that it is easily caused portion, although focus adjustment can be realized by Automatic zoom lens focusing device,
It can not be clearly observed local, therefore the present embodiment sets image adjustment component 5, and it can be by adjusting ccd sensor 25
The distance between object lens 24 automatically adjust focal length, in order to clearly be observed each position in cavity to be seen, its profit
In raising subsequent procedures quality.
Compared with prior art, the present invention illumination adjustments component 4 is set with adjust illuminating lens 22 and LED cold light sources 23 it
Between distance so that the dispersion angle that illuminating lens 22 emits beam to LED cold light sources 23 is adjusted, so adjust it is to be seen
The ray density of diverse location on cavity inner wall, it can reduce the probability to form shade and speck, consequently facilitating being formed more clear
The observation image of Chu.
The embodiment of present invention described above, is not intended to limit the scope of the present invention..Any basis
The various other corresponding changes and deformation that the technical concept of the present invention is made, should be included in the guarantor of the claims in the present invention
In the range of shield.
