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 small hole of 2mm below the lightweight bracket 8. 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 value dynamometer 7 is connected with the balance hook hanging the right pallet 4 by a string.

Abstract

The invention provides a pulling force metering device for a micro-force value measuring instrument. The device comprises an equal arm balance, and the equal arm balance comprises a balance cross beam, a left pallet and a right pallet. The right side of the balance cross beam is provided with a light support, and the lower part of the light support is provided with a small hole through drilling. The central axis of the small hole is required to be consistent with a stress axis of a right edge of the equal arm balance. A working platform is fixed above the right pallet, and is provided with a three-dimensional workbench. The micro-force value measuring instrument is fixed on the three-dimensional workbench, and a force bearing point of the micro-force value measuring instrument is connected with a balance hook for hooking the right pallet through a fine rope. The device can guarantee that the pulling force metering of the micro-force value measuring instrument with the range from 2mN to 10N meets force value metering requirements, and solves a key technical difficulty in building a (pulling) metering standard device for the verification / correction of the micro-force value measuring instrument.

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 ...
