Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.In addition, if below in described each embodiment of the utility model involved technical characteristic do not form conflict each other and just can mutually combine.
As shown in FIG. 1 to 3, a kind of attitude-control device, comprise bracing frame 1, support frame as described above 1 comprises plural spring base 11, and spring base about 11 is arranged, is provided with the vertical spring 2 of more than Hooks coupling universal coupling 12 and two between adjacent two spring bases 11, the material of spring 2 is two-way memory alloy, preferably, spring 2 is made up of CuZnAl two-way memory alloy material, its electroplating surfaces with tin.The two ends up and down of spring 2 are fixedly connected on two spring bases 11 up and down of being adjacent respectively, linked together by Hooks coupling universal coupling 12 between adjacent two spring bases 11, the top and bottom of each Hooks coupling universal coupling 12 are fixedly connected on the spring base 11 above and below it respectively, Hooks coupling universal coupling 12 can all directions rotate, thus flexible spring seat 11 all directions can be with to rotate.Preferably, described spring base 11 is overall in the form of annular discs, and such spring base 11 is under the drive of Hooks coupling universal coupling 12, and can carry out gesture stability in a plurality of directions, the dirigibility of attitude-control device is higher.
Shown in Fig. 1 ~ Fig. 3 be three spring bases 11 time situation.During use, can also expand.The spring base 11 of the top and bottom superposes spring 2, Hooks coupling universal coupling 12 and spring base 11 etc.If a spring base 11, the Hooks coupling universal coupling 12 be connected on certain one end of spring base 11, many springs 2 and multiple collet 3 are regarded as one make moving cell, then these do moving cell can carry out superposition install, such attitude-control device just can have N number of start cell operation (wherein N is positive integer).
Further, every root spring 2 is all connected with spring base 11 by collet 3, and collet 3 is fixedly connected on spring base 11, and the end of every root spring 2 is all fixedly connected on collet 3, and the material of collet 3 is machinable devitrified glass ceramics.As preferably, every root spring 2 is all threaded on the inwall of collet 3.With reference to Fig. 4, the inner chamber of described collet 3 is provided with and cuts off platform 31, cuts off platform 31 and the inner chamber of collet 3 is separated into epicoele and cavity of resorption.The arranged outside of collet 3 has external thread, and inner side is provided with internal thread, and the outside screw of collet 3 is connected on spring base 11, its inside thread linking springs 2.If two springs 2 opposing upper and lower are arranged in same collet 3, then the partition platform 31 in collet 3 can prevent two springs 2 connected in it from mutually extruding and affecting pre-stretched amount or pre compressed magnitude.Because spring 2 can carry out heat temperature raising, therefore collet 3 can effectively prevent in heat diffusion on spring 2 to other part, in case affect the normal use of other part.
Further, the quantity of the spring 2 arranged between adjacent two spring bases 11 is 2 ~ 6, these springs 2 are divided into two row and are arranged on spring base 11, such ratio is easier to the rotation direction of control spring seat 11, the rotation of spring base 11 is more accurate, not easily to shake and out of position, and contribute to the driving force improving attitude-control device.Preferred as one, if the quantity of spring 2 is set to 4, then these 4 spring rows are listed on foursquare four summits, and discoid like this spring base 11 freely can carry out gesture stability in multiple directions.
Further, select as one, the CuZnAl memory alloy material that described spring 2 can extend for high temperature during heating is made, and its phase transition temperature being in elongation state is 80 DEG C ~ 95 DEG C, and the prestretched amount of the every root spring 2 between adjacent two spring bases 11 is 10% ~ 30%.Or, alternatively, the CuZnAl memory alloy spring that described spring 2 can shorten for high temperature during heating, its phase transition temperature being in shortening state is 65 DEG C ~ 85 DEG C, and the pre compressed magnitude of the every root spring 2 between adjacent two spring bases 11 is 10% ~ 30%.Every root spring 2 first carries out prestretched or precompression when mounted, after being convenient to electrified regulation like this, it is with flexible spring seat 11 to move fast, this structure can significantly improve the response speed of attitude-control device, driving force and gesture stability angle, contributes to increasing work efficiency.
The utility model attitude-control device adopts the spring 2 of two-way memory alloy material as gesture stability executive item, and original state, spring 2 drag of attitude-control device both sides is identical, therefore attitude-control device is in equilibrium state, spring base 11 not gesture stability.When giving spring 2 electrified regulation of side, undergo phase transition at thermal excitation lower spring 2, prestretched or the precompressed spring 2 of opposite side have the trend being returned to former length, and spring 2 drag of attitude-control device both sides is unbalance, therefore attitude-control device is to a lateral movement.After the excitation of electrified regulation removes, spring 2 can return to again the identical state of spring 2 drag of original both sides, and attitude-control device comes back to original equilibrium state.The utility model not only has that driving force is large, structure is simple, can Reusability, reliability high, can work long hours, cost is low, noise is low, be convenient to the advantages such as installation, and there is the excellent properties of class biology and the structure of concision and compact, spring 2 flexible, ensures the impact resistance of attitude-control device.
If the quantity of spring base 11 is more than three, then the spring base 11 of bottom can not gesture stability, at upper all spring bases 11 all energy gesture stability, the gesture stability angle of attitude-control device can form by the gesture stability angle of multiple spring base 11 is cumulative, more than spring base 11, attitude-control device gesture stability angle is larger, the flexibility of attitude-control device is larger, its gesture stability dirigibility is higher, this attitude-control device has the excellent properties of class biology and the structure of concision and compact, achieves bionical driving and soft drive.
Those skilled in the art will readily understand; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
