The utility model is mainly characterized in that a metal non-contacting sensor is adopted; the function of digital display impact toughness is obtained; a meter disk is cancelled to simplify the structure; the impact toughness is displayed by digit, and accuracy is high; meanwhile, a communication interface is provided, which can acquire computer management and network.
Description
Affiliated field
The utility model belongs to a kind of surveying instrument of material property, specifically is a kind of metal material impact flexibility digital measuring apparatus.
Background technology
Being used for impact test method at present measures the withstand shocks instrument of Dynamic Fracture performance of load-up condition of metal material two kinds of forms is arranged, the one, dial type shock-testing machine, this testing machine structure is simple, impact the poor of the height drift angle β that rises the back by reading angle of elevation alpha before the pendulum test and pendulum, convert according to differential seat angle again by the indicator registration and to obtain the notched bar impact strength of this test specimen, the data of this test machine are to obtain by the observation of human eye, so be easy to cause error, therefore the test result that obtains neither be accurate; Another kind is advanced digitizing impact testing machine, this impact testing machine is scrambler to be installed replace carving index on the testing machine main shaft, measure ballistic work, its principle also is to utilize differential seat angle to calculate the impact flexibility of test specimen, the test result of this tester is much more accurate than the tester of dial type, and structure is much also complicated; Above-mentioned two kinds of measuring instruments be dial type or digitized all be that proving installation is installed on the main shaft, because test specimen main shaft when being subjected to the pendulum impact certainly will produce vibration and be easy to cause pointer and the digital error that shows, finally causes measurement to produce deviation.
Summary of the invention
The purpose of this utility model provides a kind of metal material impact flexibility digital measuring apparatus, the problem that exists with the surveying instrument that solves above-mentioned metal material performance.
The purpose of this utility model is to realize like this, it is made up of frame, pendulum, pendulum rod, main shaft, measurement display, its feature is, below frame, over against the pendulum rod place, install, realize that numeral shows the function of impact flexibility near switch sensor and digital operation control device and display.
Concrete structure of the present utility model has, and numerical control device is made of impulse meter and arithmetical unit, and sensor connects impulse meter, and impulse meter connects arithmetical unit, and arithmetical unit is connected with display and communication interface respectively.
Concrete structure of the present utility model has its impulse meter to adopt the time pulse counter.
The utility model adopts near switch sensor and digital indicator, and its principal character is to adopt the metal non-contacting sensor, and impact flexibility shows that with numeral the precision height is provided with communication interface simultaneously, can realize computer management and networking.

Embodiment
Below in conjunction with accompanying drawing a specific embodiment of the present utility model is elaborated.
As shown in the figure, the purpose of this utility model is to realize like this, it is made up of frame 1, pendulum 2, pendulum rod 3, main shaft 8, test display, its feature is, below frame 1, over against pendulum rod 3 places, install, realize that numeral shows the function of impact flexibility near switch sensor 4 and digital operation control device 5 and display 6.
Concrete structure of the present utility model has, numerical control device is made of impulse meter and arithmetical unit, and sensor 4 connects impulse meter, and impulse meter connects arithmetical unit, arithmetical unit is connected with display 6 and communication interface respectively, and what its impulse meter adopted is the time pulse counter.
As shown in Figure 6, existing impact testing machine principle is such, and the numerical value of the merit that pendulum is done sample (ballistic work) AK is calculated by following formula:
AK=PL (cos β-cos α) ... (1) because PL, α are constant, as disregard factors such as friction loss and air resistance, then AK is only relevant with β, and metal material impact flexibility ak is divided by the cross-sectional area F at sample grooving place.Then
Existing impact testing machine obtains the impact flexibility of material by measuring β just.The utility model is based on a kind of new measuring method of narrating below, and promptly pendulum is raised to C point required time t and β
Definite funtcional relationship is arranged:
β=f (t) ... (3) will obtain in (3) formula substitution (2) formula:
The utility model is the impact flexibility of demarcating material according to (4) formula by time t.
Measuring Time adopts pulse counting method, sensor 4 sends a pulse at regular intervals, when pendulum thrusts sample through the B point, the sensor action, the beginning pulse count, pendulum is elevated to the C point when getting back to the B point again, and sensor 4 moves again, stop counting, so just obtain the t that represents with pulse number.Carry out computing through arithmetical unit again, finally the number with notched bar impact strength shows on display, and communication interface is installed on arithmetical unit, can realize computer management and networking.The utility model can be cancelled dial plate makes its structure obtain simplifying, and data are accurate.
Claims (3)
1, a kind of metal material impact flexibility digital measuring apparatus, it is made up of frame (1), pendulum (2), pendulum rod (3), main shaft (8), test display, its feature is, in the below of frame (1), locate to install near switch sensor (4) and digital operation control device (5) and display over against pendulum rod (3).
