Description
Technical field
The utility model belongs to engineering metering apparatus field, relates to a kind of small force value calibrating installation, particularly relates to a kind of horizontal reed dynamometer calibrating installation.
Background technology
At present, reed dynamometer is used for the contact point pressure such as mechanical pressure, blattnerphone snubber assembly pressure such as relay tip pressure, electronic switch, microswitch, valve, spring pressure, index dial surveying instrument main shaft pressure, dial system equipment contact and armature pressure and the pressure of other precision, the test of pulling force, is widely used in the measurement of small force value in automated machine, exact instrument, automation control system.During test, as long as stir the object needing test with contact pilotage, make it the position moving to needs from stationary state.Reed dynamometer both can along clockwise direction, also can be tested in the counterclockwise direction, but contact pilotage arm must be vertical with the direction of push-pull effort all the time.For many years because of without vertification regulation also without standard verification apparatus, therefore this quasi-instrument in use fails well to carry out assay calibration, and its value cannot obtain unified, directly has influence on product quality.Metering institute of Heilongjiang Province had once formulated JJG (black) 1-87 " reed dynamometer " vertification regulation in 1987, after by national verification code JJG445-2000 " work dynamometer " vertification regulation substitute, but value testing does not have clear stipulaties specific standards device in calibrating project, most calibrating unit adopts the method for rope hanging counterweight to examine and determine.The gravity that rotation due to contact pilotage arm makes counterweight produce is decomposed, and contact pilotage head shapes is varied, and the gravity that counterweight is produced not necessarily all acts on contact pilotage head, and therefore this method can produce comparatively big error, and repeatability is bad, uses inconvenience.In order to improve small force measurement precision, easy to use, therefore we are on the basis that long-term detection technique accumulates, and have developed horizontal reed dynamometer calibrating installation.Its structure relative compact, measurement range is more extensive, and calibrating and calibration efficiency and precision obtain large increase.
Utility model content
The purpose of this utility model is to examine and determine and calibrate reed dynamometer, provide a kind of rational in infrastructure, measure accurately, the horizontal reed dynamometer calibrating installation of stable performance.
The utility model adopts following technical scheme to realize above-mentioned purpose.Horizontal reed dynamometer calibrating installation, comprising: supporting upright post 1, reed dynamometer contact pilotage 2, reed dynamometer clamp device 3, reed dynamometer main body 4, digital display device 5, precision indexing instrument handwheel 6, precision indexing instrument 7, base 8, force value sensor 9; It is characterized in that: precision indexing instrument 7 and supporting upright post 1 are fixed on base 8 respectively by register pin, reed dynamometer main body 4 is fixed on precision indexing instrument 7 by reed dynamometer clamp device 3, precision indexing instrument handwheel 6 is arranged on precision indexing instrument 7, force value sensor 9 is fixed on supporting upright post 1, force value sensor 9 and reed dynamometer main body 4 are in same level, digital display device 5 is arranged on base 8, and be connected by wire with force value sensor 9, the reed dynamometer contact pilotage 2 in reed dynamometer main body 4 inserts in force value sensor 9.
The utility model can reach following good effect after adopting technique scheme:
1, this calibrating installation adopts the afterburning mode of horizontal rotary to detect reed dynamometer first, ensure that the contact pilotage head Impact direction of reed dynamometer is consistent with digital display force cell Impact direction all the time, it is many that the mode overcoming traditional measurement reed dynamometer rope hanging counterweight examines and determine the uncertain factor caused, error is large, repeatability is bad, uses the shortcomings such as inconvenient.Its advantage is: under not occurring that large situation of change does not appear in large vibration, environment, and its physical construction is relatively stable, reliable, in maintenance or relatively more directly perceived when safeguarding, and convenient operation and debugging.
2, this calibrating installation uses 0.1 grade of digital display force value sensor to substitute mass weight as standard calibration reed dynamometer, overcome round-off error when counterweight combined error, quality and force value are changed, overcome reading error, improve accuracy of measurement, make measurement Simple visual more.
