Abstract
A device for adjusting posture of a camera comprises a camera, a universal joint, an upper support arm, locking screws, a lower support arm and a base plate. A ball socket structure is utilized in the universal joint design. A rotation ball head rotates freely in a supporting seat so as to adjust the space posture of the camera. The rotation ball head is locked via a fastening screw so as to fix the space posture of the camera. Meanwhile, the upper support arm can slide up and down and rotate in the lower support arm so as to adjust the distance between the camera and an identification point. The device for adjusting the posture of the camera is simple in structure, and convenient and reliable to install; and the requirement for flexibly adjusting observation view field of the camera in wind tunnel test can be satisfied.
Description
Technical field
The utility model relates to a kind of device for adjusting posture of the video camera for video measuring, is mainly used in the device that in high-speed wind tunnel model attitude video measuring system, video camera locus and attitude are adjusted.
Background technology
In the wind tunnel test process, the attitude angle of model and deflection are very important parameters, and its measuring accuracy has direct impact to the design of final aircraft.Usually ignored the vibration of model in model deadweight, model elastic deformation and test in traditional attitude, deformation measurement metering method, all there is certain error in measurement result, is difficult to meet the designing requirement that contemporary aircraft more and more becomes more meticulous.
In the model attitude video measuring, measurement result is benchmark with the video camera reference.Therefore, must meet in wind tunnel test process under the prerequisite of camera field of view requirement and guarantee its not vibration-generating.In the high-speed wind tunnel process of the test, be subject to the restriction of test chamber physical dimension, video camera is placed in wind-tunnel inside to be difficult to obtain satisfied visual field usually, and high velocity air can cause the continuous variation of positioning datum.Therefore, video camera need to be positioned over to the wind-tunnel outside, video camera is by the locus of identification point on optical glass view window tracing model.In order to meet the structural strength requirement of wind tunnel wall, the view window diameter is limited in 1 meter usually, and transonic-test section has double-deck view window.When model is different, the test attitude angle is when different, all needs to readjust position and the viewing angle of video camera so that whole process of the test is all within the visual field of video camera, this has just proposed higher requirement to the install and adjust mechanism of video camera.
The utility model content
Technology of the present utility model deal with problems for: overcome the deficiencies in the prior art, the device that provides a kind of video camera attitude to adjust, can adjust position and the viewing angle of video camera, easily and flexibly to improve to greatest extent the field of view of video camera.
Technical solution of the present utility model is:
A kind of video camera device for adjusting posture comprises: video camera, universal joint, upper branch arm, lock-screw, lower branch arm and chassis, and wherein, universal joint comprises again rotating ballhead, baffle ring, pin, housing screw and bearing; Between video camera and universal joint, by the internal thread on rotating ballhead, be connected, the ball head of rotating ballhead is placed in the ball-and-socket of bearing, and baffle ring blocks rotating ballhead at the ball-and-socket mouth, and pin is fixed together baffle ring and bearing; Rotating ballhead is locked in fixing position by housing screw; One end of upper branch arm is threaded with bearing, and upper branch arm slides up and down and rotates in lower branch arm, fixes the support platform that chassis is described video camera device for adjusting posture by lock-screw.The center of gravity of video camera is adjusted on the axis of lower branch arm by upper branch arm.
The utility model has the advantages that:
1, the utility model video camera device for adjusting posture, can adjust position and the attitude of video camera in the wind-tunnel outside, the observation visual field of effectively having improved video measuring system neatly.
2, the utility model video camera device for adjusting posture, rotate with slide unit and can firmly lock, and the design of upper branch arm adds chassis counterweight effect, has guaranteed the reliability of video measuring system benchmark, has avoided adjustment and the correction work of video camera in the process of the test.
3, the utility model video camera device for adjusting posture, simplicity of design, reasonable, location is reliable, practical.

Embodiment
As shown in Figure 1 and Figure 2, a kind of high-speed wind tunnel video camera of the utility model device for adjusting posture, comprise: video camera 1, universal joint 2, upper branch arm 3, lock-screw 4, lower branch arm 5 and chassis 6, wherein, universal joint 2 comprises again rotating ballhead 7, baffle ring 8, pin 9, housing screw 10 and bearing 11;
Between video camera 1 and universal joint 2, by the internal thread on rotating ballhead 7, be connected, the ball head of rotating ballhead 7 is placed in the ball-and-socket of bearing 11, and baffle ring 8 blocks rotating ballhead 7 at the ball-and-socket mouth, and pin 9 is fixed together baffle ring 8 and bearing 11; Rotating ballhead 7 is locked in fixing position by housing screw 10; One end of upper branch arm 3 is threaded with bearing 11, and upper branch arm 3 can slide up and down and rotate in lower branch arm 5, and sliding stroke is 500mm, fixing by lock-screw 4, the support platform that chassis 6 is described video camera device for adjusting posture.The center of gravity of video camera 1 is adjusted to by upper branch arm 3 on the axis of lower branch arm 5, to guarantee the stability of integrated adjustment, prevents from toppling over.
In the utility model, universal joint 2 adopts the socket arrangement design, and rotating ballhead 7 rotates freely to adjust the position of video camera 1 in bearing 11; Bearing 11 inside surfaces were radius goalpost face, port blocks rotating ballhead 7 by baffle ring 8, prevents that rotating ballhead 7 from deviating from from bearing 11, and pin 9 is fixed together baffle ring 8 and bearing 11, when video camera 1 is adjusted to correct position, available lock-screw 10 locking rotating ballheads 7.
