Really grasp the information that figure layer falls off.
In use, and detected member is fixed in bench vice 505 and is adjusted good position, then by adjust clump weight 305
Keep crossbeam 302 horizontal, then adjusts the distance between 307 detected member of load bar, be adjusted to contact head 309 and connect with detected member
Touching then by increasing counterweight 324 on scale pan 306, and compresses counterweight 324 with nut 325, both right by contact head 309
Detected member forms a constant loading force, then starts material surface property tester, so that detected member forms left and right
It moves back and forth, i.e. relative motion between realization contact head 309 and detected member, the Yin Mo of contact head 309 during the experiment
The effect for wiping power can generate the small displacement in left and right and be further driven to linear bearing so that load bar 307 be driven to move left and right
401 and bearing holder (housing, cover) 402 move, power is transferred to adjusting screw 404 by bearing holder (housing, cover) 402 again, to realize that friction force sensor 403 is right
Frictional force experiment is completed in the measurement of frictional force；Contact head 309 can move up and down because of the smooth situation on detected member surface simultaneously,
Contact head 309 drives load bar 307 to move up and down, and load bar 307 makes 302 the right and left of crossbeam or more is small to wave, thus
So that the data that load force snesor 315 collects loading force fluctuate, to complete elasticity modulus detection, pass through more changing-over
The experiments such as Thickness sensitivity, abrasion loss detection can be completed in contact 309, can also be even by control loading motor 214 in experimentation
Fast slowly decline, to realize that stablizing for loading force increases function, in experimentation measured piece overlay coating fall off can generate it is micro-
Small sound fluctuation, acoustical signal collector 314 can collect fluctuation signal at this time, after completing battery of tests, stop material
Surface property tester by adjusting workbench 5 completes that it is real next group of contrast properties can be carried out by the position movement of test specimen
It tests.
