Force value calibrating device for working dynamometer
Technical Field
The utility model relates to a calibrating device technical field specifically is a work dynamometer force value calibrating device.
Background
Force gauges are portable metering devices for measuring various force values or loads. Also known as a load cell. There are various classifications, which are classified into a working load cell and a standard load cell according to the objects used. The main indexes for evaluating the accuracy grade of the dynamometer are repeatability R and stability Sb. R reflects the change of data obtained by loading (unloading) for multiple times in one complete verification process; sb reflects the difference between the data obtained by assay after a period of time and the last data.
The standard dynamometers used for detecting or comparing dead weight type, lever type, hydraulic type and stacked type dynamometers are mostly in a dynamometric sensor type, and the accuracy of the dynamometric sensor type is divided into three levels of 0.01, 0.03 and 0.05. After the force sensors in various forms are matched with proper electric measuring instruments, a sensor type force measuring instrument or an electronic type force measuring instrument is formed. The standard dynamometer currently mainly uses a resistance strain sensor with wide measuring range, high accuracy and strong adaptability. The standard dynamometer used for the detection or calibration of various material testing machines is mostly in a dial gauge type, and the accuracy of the standard dynamometer is divided into three levels of 0.03, 0.05 and 0.1.
However, the existing force value calibration device has the following disadvantages: the traditional force value calibration device is usually used on a fixing frame directly welded by each mechanism, is invariably moved, needs to be disassembled again for long-distance detection, and greatly influences the use efficiency.
