Abstract
The utility model discloses a standard weight for an automatic verification system of an electronic weigher. As a weight used in the conventional manual verification is influenced by factors of manual operation, the accuracy of the weight is reduced, and the weight can not be used in the field of automation. The standard weight comprises a cylindrical standard weight body, and a hanging bar is arranged at the top of the standard weight and is fixed together with the standard weight by virtue of support bars at two ends. The standard weight is simple in structure, is made of non-magnetic stainless steel, is designed to be cylindrical, can be automatically loaded and unloaded by matching use of the closed hanging bar on the upper surface of the standard weight and a hook in the automatic verification system, and does not generate added weight in operational process.
Description
Technical field
The utility model belongs to the metrological testing technology field, relates to a kind of standard test weight that is used for the electronic scales automatic verification system.
Background technology
In the mass metrology, counterweight is the standard utensil of quality transmission of quantity value in modern times.Any calibrating activity all be unable to do without reference instrument equipment, for the calibrating of scale, just be unable to do without standard test weight.Counterweight is as the standard of calibrating weighing apparatus, and its accuracy directly influences the error of weighing apparatus legal management and consumer's interests.The counterweight of traditional-handwork calibrating reduces accuracy, and can not be used for automatic field because it receives the influence of manual operation factor.
Different counterweights applies to different metering occasions, at present the ranking score of counterweight is for 9 grade: E1, E2, F1, F2, M1, M2, M22, M3, and the counterweight of different brackets is measured according to its uncertainty and distinguished.The shape of counterweight also is diversified, and right cylinder, cone, plate shape, sheet shape or the like are arranged.
Summary of the invention
The purpose of the utility model provides a kind of standard test weight that solves the automatic field calibrating, to improve accuracy, dirigibility and the convenience of calibrating.
The utility model comprises the standard test weight body, and said standard test weight is a right cylinder, is provided with peg at the standard test weight top, and peg is fixed through the pole and the standard test weight at two ends.
The beneficial effect of the utility model is: simple in structure; With non-magnetic stainless steel as manufactured materials; Designed the standard test weight of cylinder form; Be used through the closed peg of its upper surface and the hook in the automatic verification system, realize the automatic loading and unloading of counterweight, and in operational process, can not produce impost.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Further specify the utility model technology contents below in conjunction with accompanying drawing.This standard test weight is mainly used in calibrating class of accuracy
level and following weighing apparatus.According to the difference of standard test weight quality, the size of its standard test weight and the thickness of peg also are different.
With reference to Fig. 1, the utility model comprises counterweight body 1 and peg 2.Peg 2 is positioned at counterweight body 1 top, and peg 2 is connected with counterweight body 1 through the pole at two ends, the hook that this counterweight can be through joining the type use with it be connected to Pneumatic component (like cylinder).For the standard test weight of different quality, its counterweight body 1 profile cylinder dimensions is different with the structural parameters of peg 2.The standard test weight accuracy that the utility model relates to is the M2 level, and like the standard test weight of 2.5kg, other structural parameters are that counterweight body radius is 30mm, highly are 114mm, and the peg height is 105mm, and thickness is 5mm.
