Description
Изобретение относитс к силоизмерительной технике и может быть использовано дл градуировки и поверки силоизмерителей.The invention relates to load measuring technique and can be used for the calibration and calibration of force-measuring instruments.
Известное устройство дл градуировки силоизмерителей, содержащее колеблющуюс массу, присоединенную к градуируемому динамометру через резонирующий упругий элемент, не обеспечивает требуемой точности градуировки 1.The known device for calibrating the force meters, containing an oscillating mass, attached to the calibrated dynamometer through a resonating elastic element, does not provide the required accuracy of the calibration 1.
Наиболее близким по технической сущности вл етс устройство дл градуировки и поверки силоизмерителей, содержащее станину, две инерционные массы, одна из которых выполнена в виде груза с п,патформой , резонирующий упругий элемент и возбудитель колебаний 2.The closest in technical essence is a device for calibration and verification of force meters, containing a stand, two inertial masses, one of which is made in the form of a load with n, patform, a resonant elastic element and a vibration exciter 2.
К недостаткам известного устройства относитс низка точность градуировки и поверки силоизмерителей.The disadvantages of the known device are low accuracy of calibration and calibration of load cells.
Цель изобретени - повышение точности градуировани и поверки.The purpose of the invention is to improve the accuracy of calibration and verification.
Эта цель достигаетс за счет того, что в него введен динамометр, инерционные массы выполнены различными по величине и свободно подвещены К станине, причем меньща по величине инерционна масса соединена с одной стороны с резонирующим упругим элементом, а с другой - с возбудителем колебаний через динамометр, и выполнена в виде основани с укрепленными на нем сменными грузами.This goal is achieved due to the fact that a dynamometer is inserted into it, the inertial masses are made different in size and freely inserted into the bed, and the smaller inertial mass is connected on the one hand to the resonant elastic element, and on the other to the oscillator through a dynamometer, and made in the form of a base with removable cargoes fixed on it.
На чертеже изображено предлагаемое устройство.The drawing shows the proposed device.
Станина 1 установки покоитс на упругих опорах 2, выполненных, например, в виде пружин. На станине смонтирован возбудитель 3 колебаний, который через динамометр 4 соединен с маЛой массой 5. Эта масса подвещена к станине на подвесах б, выполненных , например, в виде струн. Мала масса 5 выполнена в виде основани 7, к которому ПЛОТНО креп т на разъемных, например болтовых, соединени х сменные грузы 8.The installation bed 1 is resting on elastic supports 2, made, for example, in the form of springs. On the frame is mounted the exciter of 3 oscillations, which through a dynamometer 4 is connected to a low mass of 5. This mass is connected to the frame on the suspensions of b, made, for example, in the form of strings. The low mass 5 is made in the form of a base 7, to which TIGHTLY fastened on detachable, for example bolted, joints interchangeable loads 8.
