Embodiment Construction

[0011] Such as figure 1 As shown, the tensile force measuring device of the micro-force dynamometer includes an equiarm balance 1 with a maximum weighing of 1kg and a minimum division value of 5mg. The equiarm balance 1 includes a balance beam 2, a left tray 3 and a right tray 4, Install a lightweight bracket 8 on the right side of the balance beam 2, and drill a Ø2mm small hole under the lightweight bracket 8. The central axis of the small hole is required to be consistent with the force axis of the knife edge on the right side of the isometric balance 1. A work platform 5 is fixed above the right pallet 4, and a pair of three-dimensional workbench 6 is installed on the work platform 5 (the X, Y, Z axis directions can be moved, and the purpose is to adjust the force coaxiality of the tiny force value dynamometer 7 and use Equilibrium balance 1 is balanced), and the micro force value dynamometer 7 is fixed on the three-dimensional workbench. The stress point of the tiny force...

Abstract

The invention provides a tensile force measurement device of a micro force value dynamometer. It includes an isometric balance, which includes a balance beam, a left tray and a right tray. A light bracket is installed on the right side of the balance beam, and a small hole is drilled under the light bracket. The force axis of the knife edge on the right side of the balance is consistent; a working platform is fixed above the right pallet, and a three-dimensional workbench is installed on the work platform. The micro-force dynamometer is fixed on the three-dimensional workbench. The string is attached to the balance hook that hangs the right tray. The invention can ensure that the measurement of the tensile force value of the micro-force dynamometer in the range of 2mN to 10N meets the requirements of force measurement, and solves the key technical difficulties in establishing a measurement standard device for the verification / calibration of the micro-force dynamometer (pull direction) .

Description

technical field [0001] The invention relates to a tensile 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 measurement device used to measure the pulling force of the micro force dynamometer, so as to ensure the accuracy of the tensile force measurement of the micro force dynamometer, which is in line with the force measurement Require. [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 ...
