A device for measuring the volume of weights

Abstract

The invention discloses a weight volume measuring device, which comprises a fixed table top, a mass comparator, a lower hanging weighing pan, a liquid storage container, a weight placing tool and a weight loading unit. The mass comparator is placed at the center of the fixed table top, The lower hanging weighing pan is suspended below the mass comparator, and the lower hanging weighing pan is placed in the liquid storage container, and weight placement tooling and weight loading units are arranged symmetrically and sequentially on both sides of the liquid storage container, and the weight placement tooling It is fixed on the fixed platform and is used to place the weight to be tested, and the weight loading unit is used to grab the moving weight to realize the measurement of the weight. The device adopts track control, and moves back and forth up and down to load the weight. Due to the two positioning of the track, the positioning is more accurate and the weight measurement is more convenient. The lower suspension mechanism and air-removing device are used to reduce the error introduced by the measurement and make the measurement more accurate.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a weight volume measuring device. Background technique [0002] At present, the measurement of weights mostly adopts the hydrostatic pressure method, that is, the measurement method based on the liquid density, and the volume of the weights is calculated by the buoyancy of the measured weights in the liquid. The use of mass comparators requires high accuracy of weight measurement. There are many factors that affect the measurement accuracy in existing weight volume measurement devices. Loading and weighing are carried out on the weighing pan of measuring instruments in air and solution, but the turntable is prone to shift, resulting in inaccurate weight positioning; the shift of the balance device during weight measurement; the weight is immersed in the solution to bring air bubbles to the measuring weight Many influencing factors such as weight directly affect the accuracy of weight ...
