Description
Technical field
The invention belongs to laser lighting shadowgraph imaging engineering device technique fields, and in particular to a kind of ultrahigh speed sequence laser shade
Imaging Focalizing arrangement for camera.
Background technology
Superelevation sequence laser shadowgraph imaging instrument is that a kind of realize sets the important test of ultrahigh speed target progress shadowgraph imaging
Standby, in hypervelocity impact, UNSTEADY FLOW and targeted attitude fields of measurement research, which is essential important test
Technology.
Camera is that ultrahigh speed sequence laser shadowgraph imaging instrument is ultimately imaged medium, due to ultrahigh speed sequence laser shade into
As the image-forming principle of instrument determines that the clarity of imaging surface can only be realized by adjusting the vertical ranges of image planes to image forming medium,
By adjusting the pedestal of focusing drum image planes can be made all to be imaged to camera target surface simultaneously.
In order to realize portable, the rapid focus of 8 cameras, and consider long-time service stability and structure it is both artistic and practical
Property, the effect of Focalizing arrangement for camera is most important.Traditional locked mode all locks for screw, and a camera adjusting seat just needs
To match somebody with somebody tens of screws, and we need camera using 8 or more, it is necessary to which the screw of installation just reaches using imager
Up to a hundred, which appearance both unsightly, while adjusting screw is too many, is also inconvenient to operate.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of devices of camera rapid focus, can quickly finish camera
Focusing, while whole device, without screw, appearance is neat and artistic, highly practical.
In order to solve the above-mentioned technical problem, technical scheme is as follows：
A kind of ultrahigh speed sequence laser shadowgraph imaging Focalizing arrangement for camera, including camera connecting flange, lock nut, phase
Machine adjusting seat, clamp nut and adjustment pedestal, camera connecting flange, lock nut, camera adjusting seat, clamp nut and adjustment bottom
Seat is all columnar structured；
Camera connecting flange is placed in camera adjusting seat, for connecting the camera being ultimately imaged；
It adjusts and gap is equipped in pedestal, the bottom of camera adjusting seat is built in the gap of adjustment pedestal, is adjusted in pedestal
Aperture diameter be more than camera adjusting seat bottom diameter, camera adjusting seat be placed in adjustment pedestal in after with bottom cover shut adjustment bottom
Seat；
Clamp nut insertion adjustment pedestal simultaneously locks camera adjusting seat；
Lock nut is placed on the junction of camera connecting flange and camera adjusting seat, for locking camera connecting flange and phase
Relative position between machine adjusting seat.
The structure that total of the present invention is compressed using nut, none screw, while appearance is neat and artistic, greatly
The convenience for simplifying adjusting；The apparatus structure is simple, of low cost, can be connected with the shadowgraph imaging system of any sequence
It uses, the Fast Installation of multichannel camera is adjusted when can realize shadowgraph imaging, convenient for promoting the use of.

Specific embodiment
Embodiment 1
A kind of ultrahigh speed sequence laser shadowgraph imaging Focalizing arrangement for camera, as shown in Figure 1, Figure 2 and Figure 3, including camera
Connecting flange 1, lock nut 2, camera adjusting seat 3, clamp nut 4 and adjustment pedestal 5, camera connecting flange 1, lock nut 2,
Camera adjusting seat 3, clamp nut 4 and adjustment pedestal 5 are all columnar structured；
The structure of camera connecting flange 1 is placed on camera adjustment as shown in figure 5, for connecting the camera being ultimately imaged
In seat 3, the structure of camera adjusting seat 3 is as shown in Figure 6；
The structure of pedestal 5 is adjusted as shown in fig. 7, being equipped with gap in adjustment pedestal 5, the bottom of camera adjusting seat 3 is built in
In the gap for adjusting pedestal 5, the diameter that the aperture diameter in pedestal 5 is more than 3 bottom of camera adjusting seat, camera adjusting seat 3 are adjusted
After being placed in adjustment pedestal 5 adjustment pedestal 5 is shut with bottom cover；
The structure of clamp nut 4 is as shown in figure 8, the insertion of clamp nut 4 adjusts pedestal 5 and locks camera adjusting seat 3；
The structure of lock nut 2 is as shown in figure 4, lock nut 2 is placed on the company of camera connecting flange 1 and camera adjusting seat 3
Place is met, for locking the relative position between camera connecting flange 1 and camera adjusting seat 3.
Using locked 2 fixed camera connecting flange 1 of nut and camera adjusting seat 3, camera adjusting seat 3 and camera connecting flange
One-dimensional square push-and-pull can be carried out between 1, to adjust imaging surface to the position of camera target surface, it is ensured that obtain clearly imaging
Spot；
By camera adjusting seat 3 with that after adjustment 5 mating installation of pedestal, can realize camera adjusting seat 3 two in adjustment pedestal
It ties up direction to adjust, finally using clamp nut 4, locks camera adjusting seat 3 and the relative position of adjustment pedestal 5.
