Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also accompanying drawing 1 and Fig. 2, the embodiment of the invention comprises:
A kind ofly measure the sample holder that Low Frequency Internal Friction is used, described sample holder 2 primary structures are cylindrical tube bar 20; Described pipe bar 20 upper ends are fixed with adjusting gear 22; The center pit of described adjusting gear 22 is connected in the mode that the hole axle excessively cooperates with described pipe bar 20; Also excessively be combined with pipe close 21 in the mouth of pipe of described pipe bar 20 lower ends, be connected with lower clamp body 23 in the inner described pipe closes 21 of pipe bar 20 on axially; Described lower clamp body 23 lower ends cooperate with the through hole at place, described pipe close 21 axle center, and use screw rod 25 and pad 29 to axially fasten.Described pipe bar 20 and described pipe close 21 are stainless steel material and make.Have clamping groove 27 on the tube wall of described pipe bar 20 lower ends, be convenient to sample 12 and be installed on the pipe bar 20 inner described undercarriages concrete 23; Described clamping groove 27 notch blunt or chamferings.Described adjusting gear 22 upper/lower terminal faces all are processed with ball grooves 28, cooperate ball 4 and surface of contact to produce the rolling friction of slight drag.Described lower clamp body 23 upper ends axially on be processed with U-shaped deep trouth, it is used for device lower clamp head 24; Described lower clamp head 24 is fastening by chuck screw 26 and lower clamp body 23.
In conjunction with a kind of working method of measuring the sample holder that Low Frequency Internal Friction uses of preferred embodiments explanation the present invention:
See Fig. 2, the center pit that sample holder 2 passes on the panel 3 is installed on the panel 3, in the ball grooves 28 of adjusting gear 22 upper and lower end faces, put into ball 4, guarantee that ball 4 can drive sample holder 2 flexible rotatings, the upper surface of adjusting gear 22 is pushed down with intermediate plate 3, and utilize trip bolt 11 to be fixed on the panel 1, with fixed sample support 2.Sample holder 2 is not offset with intermediate plate in rotation process, sample holder 2 is played certain radial location.
During the clamping sample, first upper end and vertical pendulum bar 6 bottoms of sample 12 are fixed, and the lower end of sample 12 is installed on the lower clamp body 23 on the sample holder 2, cooperate chuck screw 26 fixing by lower clamp head 24, a rectangle mirror 10 has been installed on the vertical pendulum bar 6, for the signal that reflects and the reception measuring equipment sends, the upper end of vertical pendulum bar 6 hitches counterweight 8 with a thin cotton thread 9 and is fulcrum by supporting mechanism 7, the sample 12 that vertical pendulum bar 6 is connected reaches balance, when vertical pendulum bar 6 is rotated by tangential stress, because the rigidity of vertical pendulum bar 6 is much larger than sample 12, the resistance of 9 pairs of rotations of thin cotton thread of upper end is very little simultaneously, can ignore, so tangential force can only make the sample 12 on the vertical pendulum bar 6 produce distortion.
In the operating process, when the rectangle mirror 10 on being installed in vertical pendulum bar 6 can not be aimed at receiving sensor, just need to adjust the position of vertical pendulum bar 6, because the upper end of vertical pendulum bar 6 is thin cotton threads 9, so can only adjust by the position of adjusting sample holder 2 position of vertical pendulum bar 6, when rotating the driving gear 5 that meshes with adjusting gear 22, sample holder 2 just can be clockwise or inhour rotate, make the rectangle mirror 10 that is installed on the vertical pendulum bar 6 aim at the receiving sensor of measuring equipment, just can carry out next step operation subsequently, finish surveying work.
The characteristics such as the present invention is a kind of to measure the sample holder that Low Frequency Internal Friction is used, and what provide a kind ofly measures the sample holder that Low Frequency Internal Friction is used, and its primary structure adopts stainless steel material to make, and has good rigidly, and is high temperature resistant, anti-oxidant.And it is reasonable in design, and is simple in structure, and the method for utilizing ball to cooperate with gear realizes the purpose of steady angular adjustment.Simultaneously, have the clamping groove at the pipe bar, so that the clamping process of sample is more quick, also can change different specimen holders according to the needs of experiments of measuring in the measuring process.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
