Description
Technical field
The present invention relates to a kind of calibration equipment, relate in particular to a kind of weight detecting equipment, specifically be meant a kind of gram group counterweight volume calibrating installation.
Background technology
Usually to examine and determine it with the degree of accuracy of counterweight in order to guarantee weighing, in the calibrating project wherein except examining and determine the measurement to the quality of counterweight, because the volume size of counterweight will influence counterweight in the buoyancy size of measuring suffered counterweight place medium, thereby also will examine and determine its volume.
Traditional volume measuring method has a variety of, and relatively Chang Yong method then is workpiece for measurement to be put into the container of full of liquid, and putting into of workpiece can make that liquid overflows, and reaches the purpose of measuring workpieces volume by the volume of measuring overflowing liquid.But because this measuring method is subjected to the influence of liquid tension easily, thereby the volume of the feasible liquid that overflows can not be represented the volume of workpiece for measurement fully, and precision is relatively poor.
Have the people that workpiece is measured its quality respectively now in two kinds of different mediums, because the density of medium difference, the buoyancy size that it is subjected to is also different, thereby the quality of measuring also is different, can calculate the volume of workpiece again by the way of mathematical modeling.This measuring method has the precision advantage of higher, thereby is used widely.
Thereby how to guarantee that workpiece carries out the weighing of quality in two media precision has just become very crucial problem, as everyone knows, utilize the quality comparator very high to the precision that workpiece carries out quality weighing, but since the quality comparator when requiring weighing workpiece to place precision very high, promptly require the center of gravity of workpiece for measurement will be on the center of gravity reference line of mass balance instrument.Usually dispose the balance device of various center of gravity self-alignings for the quality comparator, after can guaranteeing that promptly workpiece is placed on the balance device, the center of gravity of workpiece and balance device is on the center of gravity reference line, if but when measuring, it still is the accuracy of workpiece calibration that beat taken place balance device words can influence, thereby in order to guarantee not beat of balance device, to take usually long time place work piece with the center of gravity of the center of gravity that guarantees workpiece and balance device all on the center of gravity reference line.The placement of workpiece is at present still manually placed usually, thereby still has the problem that standing time is long, waste time and energy at present.
Summary of the invention
