Lower suspension mechanism for weight volume measurement

Abstract

The invention discloses a lower suspension mechanism used for weight volume measurement. The lower suspension mechanism comprises a mass comparator induction scale pan, an induction connecting sheet I, an induction connecting sheet II, a placing rack and rollers. The induction connecting sheet I and the induction connecting sheet II are symmetrically connected on the two sides of the mass comparator induction scale pan to form similar shoulder pole structures; the two ends of the U-shaped hollow placing rack are fixedly connected on the lower end of the induction connecting sheet I and the lower end of the induction connecting sheet II respectively, semicircular placing grooves are formed in the two rack plates of the placing rack respectively, each roller is composed of a roller body anda roller neck, the roller necks are contained in the placing grooves, and the roller bodies are located in the hollow portions of the placing rack. The lower suspension mechanism of the shoulder polestructure is good in balance, the center point of the mass comparator can be kept unchanged to the maximum extent, and measurement errors caused by center unbalance loading are reduced.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a lower suspension mechanism used for weight volume measurement. 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. When measuring weights, it is required that the weights must be placed on the center reference line of the mass balance instrument. If the balance device is shifted during the measurement, it will directly affect the accuracy of the measurement. At present, most measuring devices use hooks to hang the lower weighing pan Under the mass comparator, this kind of hook connection is easy to make the measurement center point shift, and the balance is not good. The invention provides a lower suspension mechanism used for weight volume measurement to solve t...
