Description
Technical field the utility model relates to a kind of data computation device, and particularly a kind of Brinell hardness and Vickers hardness of being used for measured, and by input impression size and necessary test parameters setting, directly calculates the counter of hardness number.
Known Brinell hardness of background technology and Vickers hardness measuring method be, by the pressure head of sclerometer with definite shape, size, defeats into the test specimen surface with certain test, measures the size of impression then, again by tabling look-up and interpolation arithmetic obtains hardness number.
The Brinell hardness of standard and Vickers hardness test have constituted the test (or claim scale of hardness) of various ways according to the various combination of test condition, also exist other modes such as hammering Brinell test and impact type Brinell test simultaneously.
Various test methods all have its different computing formula, calculating parameter, have in addition do not have computing formula to have only the calculating numerical table.
The major defect of current methods is that its process complexity is loaded down with trivial details, the error of calculation is bigger.Because the form of this two classes hardness test is various, the quantity of numerical table and the workload of tabling look-up are very big in addition.
Utility model content the purpose of this utility model is to provide a kind of hardness calculation device, solves loaded down with trivial details tabling look-up and interpolation arithmetic in the hardness test operation, and can help to improve the accuracy of hardness test.
The technical solution of the utility model is as follows:
A kind of hardness calculation device, comprise microprocessor, storer, LCD and hummer is characterized in that: also comprise impression/parameter button, the pressure head parameter is provided with button, cloth dimension conversion keys, impression input button calculates button, single two-parameter calculating conversion keys, statistic behavior conversion keys and inquire and browse button; Each button all links to each other with the input port of microprocessor, and LCD links to each other with the output port of microprocessor with hummer, and storer links to each other with the I2C STD bus with microprocessor.
Also comprise power button, it links to each other with the input port of microprocessor.
Also comprise all batteries of required power supply of hardness calculation device circuit are provided, it is installed in the battery case of hardness calculation device.
Good effect of the present utility model is: this hardness calculation device manages coordination with all kinds of computing formula, calculating parameter and calculating numerical table with microprocessor, and the user only needs just can calculate hardness result by the input of simple setting and test impression size.Can make things convenient for and simplify the process of the test of all kinds of Brinell hardness and Vickers hardness greatly, improve the accuracy of test findings data processing to a certain extent.
Simultaneously, this hardness calculation device is also integrated relevant data statistics and data storage function simplified the statistical study process in the hardness test.
