Embodiment Construction

[0012] The current force value standards are all traceable to the gravity generated by mass weights ( F = mg). Since the force application method of the force value weight is always vertically downward, how to apply the force value generated by the force value weight that is always vertically downward to the compression force dynamometer step by step, completely smoothly and effectively , and there can be no impact or swing phenomenon. It is an urgent problem to be solved that the axis line of the force value of the weight loaded step by step must be consistent with the center line of the compressive force received by the micro force dynamometer.

[0013] In view of the above problems, a tensile force measurement device of a micro force value dynamometer is provided, which includes an equiarm balance 1 with a maximum weighing capacity of 1 kg and a minimum division value of 5 mg, and left hooks are respectively installed on both sides of the balance beam 2 3. A vertical penda...

Abstract

The invention provides a metering device for verifying / calibrating the compressive force of a small force value dynamometer, which includes an isometric balance, which includes a balance beam, a left hook, a right hook, a left tray, and a right tray. The left hook and the right hook are respectively installed on both sides of the beam, and a plumb pendant is installed on the left hook. The central axis of the plumb pendant is consistent with the force axis of the left knife edge of the balance. , A π-shaped work platform is fixed above the left pallet, a pair of three-dimensional workbench is installed on the π-shaped workbench, and the micro force value dynamometer is fixed on the three-dimensional workbench. The invention can ensure that the measurement of the compression force value of the micro-force dynamometer in the range of 2mN to 10N meets the force measurement requirements, and solves the key technical difficulties in establishing a verification / calibration micro-force dynamometer (compression direction) measurement standard device.

Description

technical field [0001] The invention relates to a compression force measurement device of a micro force value dynamometer, which belongs to the technical field of measurement devices. Background technique [0002] The micro-force dynamometer we define here refers to a dynamometer with a force measurement range of 2mN~10N, hereinafter referred to as a "micro-force dynamometer". The measurement device (pull direction) of the micro-force dynamometer is a verification device used to measure the micro-force dynamometer to ensure the accuracy of the measurement indication of the micro-force dynamometer and meet the force measurement requirements. [0003] At present, the measurement value transmission work of the micro-force dynamometer has not been carried out in China. JJG2045-2010 "National Metrology Verification System Table for Force Value (≤1MN) Measuring Instruments" only stipulates the traceability relationship of force value measuring instruments above 10N. For the meas...
