Description
Technical field
The present invention relates to fluid damping device technical field. More specifically, it relates to a kind of magnetic current for vertiplane high-definition camera installation and debugging becomes vibroshock.
Background technology
Aviation machine construction environment is severe, and job status is complicated, and the requirement closing heavy parts is very high. high-definition camera vibroshock is as one of important Parts in aviation machine, it is desired to it is conveniently suitable for, structure is light, reliability height. in high-definition camera use procedure, helicopter vibration is big, and the shooting effect of camera is had very big interference, camera shooting image blurring unclear, it is thus desirable between camera and vertiplane mounting shock absorber, reduce helicopter vibration to the impact of camera. current vibroshock on the market generally has air cushion shock absorber, rubber absorbers and steel rope damper etc. after these vibroshocks dispatch from the factory, its elasticity and damping just determine, can not carry out again regulating and change, and in the installation process of high-definition camera, need to install and can ensure that high-definition camera photographs the vibroshock with suitable elasticity and damping of clear picture effect, and in order to install the vibroshock needed for the work of applicable high-definition camera, then it needs to be determined that the elasticity of vibroshock required during high-definition camera shooting clear picture under helicopter flight state and damping parameter, then according to the parameter determined, suitable vibroshock is installed, therefore in order to reduce the convenient and swift of test job, need to design low-cost and high-performance vibroshock easy to use.
Summary of the invention
It is an object of the invention to provide a kind of magnetic current for vertiplane high-definition camera installation and debugging and become vibroshock, conveniently regulate the elasticity between camera and vertiplane and damping.
For achieving the above object, the present invention adopts following technical proposals:
Magnetic current for vertiplane high-definition camera installation and debugging becomes a vibroshock, and described magnetic current becomes vibroshock and comprises: pedestal, coil and magnetic flow liquid;
The 2nd connection section that described pedestal comprises the first connection section being connected with camera and admittedly connects with vertiplane; Described first connection section comprises the first accommodation section holding coil and holds the 2nd accommodation section of magnetic flow liquid, and described first accommodation section is looped around the periphery of described 2nd accommodation section.
Further, described magnetic current becomes vibroshock and also comprises groove body; Described first connection section comprises a groove, and the sidewall of described groove is provided with the first accommodation section holding coil, and described inside grooves accommodates groove body, and the sidewall of described groove body is provided with the 2nd accommodation section holding magnetic flow liquid.
Further, described first accommodation section is the first annular groove, and described 2nd accommodation section is the 2nd annular groove.
Further, described magnetic current becomes vibroshock and also comprises motion bar, and one end of described motion bar is stretched into the inside of groove body and is connected with bottom land.
Further, described motion bar is provided with threaded hole, and the material of described motion bar is aluminium.
Further, the 2nd connection section of described pedestal is threaded rod, and the material of described pedestal is aluminium.
Further, the material of described groove body is vulcanized rubber.
The useful effect of the present invention is as follows:
(1) structural reliability height, is provided with vulcanized rubber between pedestal and motion bar, coil is arranged in base seat groove, compact construction. Pedestal is all aluminum casting with motion bar and becomes, and therefore structural weight is little.
(2) elasticity and damping are adjustable, are provided with coil and magnetic flow liquid in vibroshock, can change elasticity and the damping of vibroshock by changing the size flowing into coil current.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
Fig. 1 is the overall appearance schematic diagram that magnetic current of the present invention becomes vibroshock;
Fig. 2 is that magnetic current of the present invention becomes shock absorber structure schematic diagram.
In figure: 1-pedestal; 2-coil; 3-groove body; 4-motion bar; 5-base thread bar; 6-magnetic flow liquid; 7-threaded hole.
Embodiment
In order to be illustrated more clearly in the present invention, below in conjunction with preferred embodiments and drawings, the present invention is described further.
As illustrated in fig. 1 and 2, magnetic current change vibroshock comprises pedestal 1, coil 2, groove body 3, motion bar 4, threaded rod 5, magnetic flow liquid 6 and threaded hole 7; The 2nd connection section that pedestal 1 comprises the first connection section being connected with camera and admittedly connects with vertiplane; First connection section comprises the first accommodation section holding coil 2 and holds the 2nd accommodation section of magnetic flow liquid 6, and the first accommodation section is looped around the periphery of described 2nd accommodation section; Concrete, the first connection section comprises groove, and the sidewall of groove is provided with the first accommodation section holding coil 2, and inside grooves then holds groove body 3, and the sidewall of groove body 3 is provided with the 2nd accommodation section holding magnetic flow liquid 6;
First accommodation section is the first annular groove, and the 2nd accommodation section is the 2nd annular groove, one end of motion bar 4 is stretched in groove body 3 and bottom land with groove body 3 is connected, the material of groove body 3 is vulcanized rubber, motion bar 4 is provided with threaded hole 7, camera is connected with motion bar by threaded hole 7, and because motion bar 4 is connected with the groove body 3 of vulcanized rubber material, thus between motion bar 4 and pedestal 1, it is provided with elasticity and damping, simultaneously, because pedestal 1 is also provided with the first annular groove installing coil 2, the sidewall of groove body 3 is provided with the 2nd annular groove groove holding magnetic flow liquid 6, first annular groove is looped around the periphery of the 2nd annular groove, when coil 2 is energized, just can form electromagnetic field, the state of magnetic flow liquid 6 is changed, thus produce damping, therefore the vibration load being passed to pedestal by vertiplane can reduce, thus camera is played the effect of damping, the bottom of pedestal 1 outside groove is provided with threaded rod 5, pedestal 1 is connect admittedly by threaded rod 5 and vertiplane.
Installation and debugging of the present invention are simple, and quality is little, is suitable for use in the damping of vertiplane high-definition camera. In use, start vertiplane engine, allow the vibration of vertiplane be in normal operation state, open the image that high-definition camera observes shooting, in coil, lead to the electric current into different size, observe the image of camera shooting, until image stabilization is clear; Recording the size of electric current in now coil, the relevant equipment of application measures elasticity and the damping of now vibroshock of the present invention, can determine to need the performance perameter of the vibroshock installed, reach the object of high-definition camera damping debugging.
