Summary of the invention
The utility model is designed to overcome the deficiencies of the prior art to provide a measurement of characteristics of a good, the technical indicators in line with national standards GB/T13634-2008 and international standards ISO376: 2004 in a characteristic requirements, and simple structure, shape Small light weight, the figures show a sub-shaped uniaxial tension and compression standard dynamometer.
The utility model is intended to achieve the following technical solutions A uniaxial tension and compression Asian font standard dynamometer, which includes capping one, ball two, pull the head 3, the right cantilever 4, left cantilever 5, the elastic member 6, the table frame 7, the lever 8, the rod 9, the digital indicator 10, the lower slider 11, a base 12 formed, characterized in that: lid 1 and the ball 2 is fixedly connected together, the measured pressure 3 placed on the upper slider concave ball, the elastic member 6 was sub-vertical beam-shaped structure, which pull the head 3, the drop-down head 11, the right cantilever 4, 5 composed of one cantilever left and right cantilever 4 and Table frame seven solid together, left lever 8 cantilever 5 and fixedly connected together, the lower end of the table frame 7 install a digital dial gauge 10, the lower end of the lever 8 9 installed measuring rod, measuring rod 9 right end face and digital dial gauge in close contact with the header 10, the base 12 has a head 11 fitted with pull-down the internal threads, the measured pressure is the fashion base 12.
As the utility model elastic element 6 is designed to sub-shaped stand beam structure, than the known flat annular curved beam structure dynamometer, it's more than half to reduce weight, it also reduces the relative error return into the two more than one half, with good metrological characteristics, technical specifications than JJG144-2007 "standard dynamometer" in 0.3, to GB/T13634-2008 and ISO376: 2004 standard specifies a characteristic requirements, the beneficial effects reflected in:
1, can draw and can press, simple in structure, the shape corpusculum is light, the material-saving saving of labor, cost is low, meets low-carbon (LC) spirit.
2, accuracy is high, and indicating value is stable, advances the backhaul relative error less than 0.30%, and each item technical indicator is higher than 0.3 grade among the JJG-2007, reaches the characteristic requirements of 1 grade of GB/T13634-2008 and ISO:2004 standard, has solved domestic demand, and has realized in line with international standards.
3, digital dial gauge indicating value digital display is directly perceived, and can be connected with computing machine, realizes functions such as data processing and printing as a result.
