Description
Technical field
The utility model relates to the novel screw type loading frame of precision optical machinery and precision optical instrument.
Prior art
Various Experiments of Machanics be unable to do without the loading to test specimen, and the common mechanical load that is loaded with is as tensile, compressive, bending, turn round; Thermal force; Dynamic loading is as impact, explosion; Random load etc.The loading frame of using for the mechanical load of a single state also is not quite similar.As the lever loading frame is to utilize lever principle to load; The linear bearing loading frame is to utilize linear guides to slide to load.Above-mentioned loading frame shortcoming clearly, as the loading center be difficult to regulate, can not apply torsion load, be difficult to apply quantitative load, structural instability, bulky etc.
And test the height that most situation can only be regulated measured object, can not often arbitrarily move the experiment measuring instrument.So design the suitable loading frame that can conveniently regulate the loading center, be the key of this class work success.
Illustrated in figures 1 and 2 is existing two kinds of loading frame structural representations that generally use.Wherein:
Shown in Figure 1 is a kind of existing commonly used lever loading frame, and it comprises: weight equalizer 11, fulcrum 12, inner thread sleeve 13, load screw rod 14, measured object 15, fixedly hook 17, rear portion stiffening plate 18 and the balance stem 19 of degree of freedom base 16, extension sliding weight of steelyard.Its principle of work is:
At first want shifting balance weight 11 to make balance stem 19 levels, allow the initial load be zero; Rotation inner thread sleeve 13 makes its loading end touching on measured object 15, and keeps the level of balance stem 19; Hang the sliding weight of steelyard of constant weight on the hook 17 of hanging sliding weight of steelyard, by loading the loading end of screw rod 14, power is applied on the measured object 15.
Its shortcoming is:
1, first step adjustment is very difficult and not too accurate, and keep initial load is zero always;
