Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the key diagram of cup depth.
Embodiment
Following according to Fig. 1 and Fig. 2, a better embodiment of the present utility model is described.
As shown in Figure 1, the utility model comprises a base 1, the rotating mechanism 2 that is arranged on this base 1 and the utility model is rotated, one connect base 1 and and this base 1 vertical and be with the lifting column 4 of scale, horizontal direction at base 1, also has a crossbeam 8 that is slidedly arranged on this lifting column 4 and band scale, the sliding perpendicular displacement survey sensor 7 of establishing a band probe 71 on the crossbeam 8; In the one side, the horizontal shift measurement mechanism 9 of a band scale is set also.On the base 1, the column latch mechanism 3 of a scalable column 4 is set also; On the column 4, but the crossbeam latch mechanism 5 of a fixed cross beam 8 is set also; On the crossbeam 8, but the horizontal fixed mechanism 6 of a fixed vertical displacement transducer 7 and horizontal shift measurement mechanism 9 is set also;
Below be the principle of work that the utility model is used to measure cup depth:
Rotation rotating mechanism 2 makes crossbeam 8 be positioned at the top, testing site, adjusts lifting column 4 and crossbeam 8 by column latch mechanism 3 and crossbeam latch mechanism 5, and the probe 71 of perpendicular displacement survey sensor 7 is touched near the testing site; Adjust horizontal fixed mechanism 6 and rotate rotating mechanism 2, make the probe of perpendicular displacement survey sensor 7 correctly navigate to the testing site; The displacement readings X1 (mm) of record perpendicular displacement survey sensor 7 and the reading on lifting column 4 and the crossbeam 8 at this moment; Rotation rotating mechanism 2 makes the probe 71 of perpendicular displacement survey sensor 7 depart from the testing site; The testing site is loaded, carry out testing site depression test; Behind the stand under load of testing site, adjust according to the reading on above-mentioned lifting column 4 and the crossbeam 8, make the probe 71 of perpendicular displacement survey sensor 7 get back to former testing site, the displacement readings X2 (mm) of record perpendicular displacement this moment survey sensor 7 can obtain cup depth d (mm)=X2-X1.
Below be that the utility model is used to measure the principle of work of Surface Method to angle:
At first, according to testpieces curve form and drawing, confirmed test point maximum curvature planar orientation and normal direction angle measuring route; Rotation rotating mechanism 2, column latch mechanism 3, crossbeam latch mechanism 5, adjust lifting column 4 and crossbeam 8, make crossbeam 8 be positioned at maximum curved surface plane, testing site, and adjust probe 71 that horizontal fixed mechanism 6 makes perpendicular displacement survey sensor 7 and contact with the testing site and reach and be positioned at normal direction angle measuring route, Rotary cloumn latch mechanism 3, make lifting column 4 fixing, rotate horizontal fixed mechanism 6 simultaneously, the probe 71 of perpendicular displacement survey sensor 7 is contacted with the testing site well, (X1 X2) adjusts to X1=X2 with symmetria bilateralis position, testing site by the horizontal shift measurement mechanism on the crossbeam 8; Pop one's head in 71 at X1 by read sensor on the perpendicular displacement survey sensor 7 simultaneously, the measured value Y1 at X2 place, Y2; Get Y=(Y1+Y2)/2, and record.By tg α=Y/X1 or Y/X2, try to achieve and the platform vertical axis between angle α, i.e. testing site place normal direction angle.
