Embodiment:
With reference to Fig. 1, Fig. 2 and Fig. 3, measurement of the steel plate instrument, it includes base 1, cantilever 2, screw mandrel lifting slide unit 3 and vernier caliper 4; Base 1 is permanent magnetic chuck preferably, whether controls adhesive by change-over switch 11, stablizes and is pull-in on irony testing stand, guarantee that cantilever 2 does not rock during measurement; Cantilever 2 one end is fixed on base 1, and another is positioned with screw mandrel lifting slide unit 3, can adopt fixing or location of sliding, and the screw mandrel lifting slide unit 3 of location of sliding can slide along cantilever 2, and measurement range is larger; Screw mandrel lifting slide unit 3 comprises fixed block 31 and elevator 32, and be slidably matched by dovetail groove 33, and be positioned with screw mandrel 34 at fixed block 31 1 side shaft, screw mandrel 34 end winding support stretched out outside fixed block has knob 36; Elevator 32 internal fixtion has nut 35, and this nut 35 is screwed on the thread segment of screw mandrel 34, regulates the lifting of elevator 32 by knob 36, and can the height and position of lock-bit elevator 32.
Described vernier caliper 4 comprises main scale 41, vernier 42, pit gauge 43 and back-moving spring 44; This example does suitable improvement to vernier caliper 4, unwanted internal measure-hand and external pelivimetry pawl is removed, and because the wave value measured is very little therefore by the contraction in length of vernier caliper, and proper extension depth survey bar makes it to stretch out blade.Described main scale 41 is fixed on elevator 32, and back-moving spring 44 is located between vernier 42 and main scale 41, makes vernier 42 self-zeroing, be in wait measuring state all the time by this back-moving spring 44; Vernier 42 has extended outwardly a lever 45, and the pit gauge 43 fixed with vernier 45 stretches out the end of main scale 41, sample surface of can directly conflicting.
Measuring method: the first step, permanent magnetic chuck base 1 is utilized to be pull-in on the irony testing stand at thin plate sample edge, because the scope of side wave or middle wave is usually all little, so also can directly permanent magnetic chuck base be pull-in on testing stand through measurement sample in the position not affecting measured value on thin plate sample, in magnetic force change-over switch " ON " before to determine permanent magnetic chuck base 1 place position, pit gauge lower end is moved to simultaneously peak to be measured top (by knob 36 by the coarse adjustment of pit gauge lower end to close to thin plate, be easy to like this find peak to be measured), second step, regulates the knob 36 in screw mandrel lifting slide unit 3, vernier caliper 4 is declined, until the wave place (needing range estimation) of thin plate sample is just touched in pit gauge bottom, 3rd step, manual depression lever 45, vernier 42 together moves down together with pit gauge 43, until pit gauge 43 is by compressive strain under thin plate sample wave, (acting force only makes wave transformation, and thin plate thickness of sample can not be out of shape because pit gauge presses down) conflict on testing stand, now, on main scale 41, reading is wave height.Once shed lever two-way pressure, vernier 42, under back-moving spring 44 acts on, automatically returns to the position of zero, waits for that next time measures.
The utility model adopts the vernier caliper of improvement, and as survey instrument, principle is ripe and precision is high, and the reading mode of vernier caliper, also can be scale-type, pointer-type, or digital display type select a structure.And according to different reading mode, precision can reach ± and 0.03mm to ± 0.02mm, improve more than thin plate sample wave measurement precision order of magnitude.
Moreover, the conveniently needs of diverse location Quick Measurement or nonferromugnetic material test desk, base 1, except adopting permanent magnetic chuck, also can be hand-screw screw mandrel fixture, can directly be folded in testing stand edge, locked by screw mandrel, and in this structure, the location between cantilever 2 and base 1, can adopt axle to locate, make cantilever 2 can be rotatable around base 1, facilitate comprehensive measurement; Base 1 also directly can utilize the column on testing stand, cantilevered axle is positioned at column, can reaches same effect.And cantilever 2 itself also can have two class formations, a class is rigid arm, and two classes are folding or telescopic arm; If the former, the fixed block in described screw mandrel lifting slide unit 3 can adopt and be slidably located on cantilever 2, by the slippage on cantilever 2 of screw mandrel lifting slide unit 3, to meet the need of diverse location measurement; And adopting folding or telescopic cantilever, nature directly can change jib-length or angle, certainly coordinates the axle location of cantilever, makes its dirigibility just higher.
