Shown in Figure 21 and 22, also be provided with two-layer four otic placodes 14 up and down on the sample stage 1,15,16, upper strata otic placode upper surface is concordant with chute 21 part upper surfaces, lower floor's otic placode lower surface has with a certain distance from chute 21 part bottom surfaces, otic placode 14, on 15 respectively correspondence be provided with through hole 141 and 151, up and down on two otic placodes 16 respectively correspondence through hole 161 is set, by through hole 141,151 and 161, photoconduction axle 8 and fine setting axle system are installed on sample stage 1, photoconduction axle 8 is assemblied on the sample stage 1 by the threaded hole 141 on unthreaded hole on the otic placode 15 151 and the otic placode 14, and its revolving shaft is vertical with sample stage 1 bottom surface.The fine setting axle system is made up of 91,92 and inner nuts 93 of fine setting 9, two bearing of axle, after bearing 92 inner ring and inner nut 93 wringing fits, through hole wringing fit on outer ring and the lower ear plate 16, through hole wringing fit on another bearing 91 outer rings and the upper ear plate 16, fine setting axle 9 is by the little double-screw bolt and inner nut 93 threaded engagement, upper shaft neck portion and loose removable cooperation of bearing 91 inner rings of its lower end, form the fine setting axle system, be arranged on the sample stage 1, the revolving shaft of fine setting axle 9 is vertical with sample stage 1 bottom surface.Simultaneously, photoconduction axle 8 is set on the sample stage 1 and probe plate 7 is set with the place of finely tuning axle 9.The outline center is provided with a threaded hole on the probe plate 7, in order to the probe 71 that assembles external displacement transducer.Probe plate length direction two ends are symmetrically arranged with two lugs, with the screwed hole of centre symmetry threaded hole and a unthreaded hole are set respectively on the lug, cooperate with photoconduction axle 8 and fine setting axle 9 respectively, to guarantee rotating the fine setting axle at 9 o'clock, probe plate 7 and assembling probe 71 thereon can only move freely in vertical direction.Probe 71 is the probe of non-contact displacement transducer, and non-contact displacement transducer comprises eddy current displacement sensor, capacity plate antenna displacement transducer, optical fibre displacement sensor etc.
As shown in figure 23, anchor clamps of the present invention are placed on the frame platform 524 of indentation test machine, the pressure head 523 of indentation test machine is suspended on the crossbeam 525 of indentation test machine frame, be connected with the external sensor moving-member---fixing pressure head 523 on the support of Target Board 522, the position of Target Board 522 can be adjusted, guaranteeing probe 71 centerings of Target Board 522 and external sensor, and the axis of the probe 71 of sensor and Target Board 522 planes are perpendicular.Directly measure the relative displacement of fixed part probe 71 with the moving-member Target Board 522 of external sensor, can reject most of frame flexibility in the indentation test machine effectively, thereby reduce the frame flexibility that comprised in the displacement measurement data as much as possible.
The function of these anchor clamps has: the clamping and the locomotive function of sample positioning function, external independent displacement sensor.
First's function realizes planar translation of sample, simultaneously, realizes the anchor clamps easy conversion of sample bearing part between plane positioning platform and integrated accurate rigid platfor.When mobile example, unclamp clamping screw, anchor clamps are in the plane positioning platform status, and sample is moved to testing position, and clamping screw makes anchor clamps become interim integral structure again.
Second portion is chosen the very near part frame of separating test sample in whole frame, insert external displacement transducer, guarantees that simultaneously external sensor can adjust to best operational position at the trial.
In these anchor clamps, displacement measurement is the displacement of the moving-member of external sensor with respect to fixed part.Wherein, local frame flexibility is the stand stretch between external sensor moving-member (as: Target Board of eddy current displacement sensor) bite and fixed part (as: probe of the eddy current displacement sensor) bite.The design of the modular construction of this compact has reduced the content of displacement measurement mid frame flexibility significantly, the algorithm by data processing again, the influence that can reject the frame flexibility effectively.Pressure head is in the process of approaching the sample testing surface, and load is zero in theory, and this part stroke (promptly approaching stroke) in data processing, by determining to be pressed into zero point, also can be good at rejecting.
So, at first on the jig Design structure, the major part of whole frame flexibility is rejected from displacement measurement, rejected remaining local frame flexibility and approach stroke by data processing again, finally obtain compression distance.
It is to be noted and any distortion of making according to the specific embodiment of the present invention all do not break away from the scope that spirit of the present invention and claim are put down in writing.
