Abstract
The utility model discloses a rubber digital display durometer which is a dynamics pointer for assaying the hardness of the rubber and plastics, which comprises a pressured needle (1), an indenter foot (2), a spring (3) and an indicating arrangement (5). The working principle of the rubber digital display durometer is that the utility model makes the pressured needle (1) smoothly contact with the measured rubber or the plastics after switching on, exerts external force, makes the expansion and contraction of the pressured needle adjust the resistance of a potentiometer for commanding the indicating arrangement to directly read out indication on a liquid crystal display under the function of the spring (3). The utility model alters traditional mechanical rubber hardness measurement instrumentations, and has the advantages of convenient operation and high precision.
Description
The utility model is to measure scleroscopic improvement invention about mechanical type total indicator reading rubber, is a kind of with the mensuration rubber of numeral demonstration and the table meter of plastics hardness.
In the prior art, the table meter of measuring rubber, plastics and analog hardness thereof all adopts the Shao Er hardness test method of mechanical type total indicator reading, this table meter also has pressing, presses foot, spring and indicating device, but this sclerometer is the gear that utilizes the flexible drive of compression set spring to contact with pressing to rotate and makes pointer reading on index dial, shortcomings such as pointing accuracy is poor, pointer is ineffective often occur.
In view of the deficiency that known technology exists, the purpose of this utility model is to provide a kind of modern durometer that shows reading with numeral.It is easy to use that this sclerometer can reach, the display precision advantages of higher.
The utility model is realized as follows, its table meter includes pressing, presses foot, spring and indicating device, one end of pressing contacts with sensor, the connected mode of sensor and indicating device is for being electrically connected, be that pressing is contained in the pressure foot center with spring, one end of pressing contacts with potentiometer (promptly finely tuning sensor), work as energized, pressing firmly is pressed in the measured object surface, when applying external force, thereby under the effect of spring, pressing is stretched to adjust the resistance commander liquid crystal indicator of potentiometer to show reading.To reach the hardness of similar articles such as measuring rubber and plastics.
The utility model and prior mechanical pointer indication sclerometer is compared, and has easy to use, accuracy of reading, and rational in infrastructure, make easily, its electric part only need be purchased standard component and assemble and get final product.Press the rubber digital display sclerometer of the utility model design motif made, will play positive result of use at rubber and plastic industry mensuration hardness.
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is an electrical schematic diagram of the present utility model
Fig. 3 is power supply process Installation figure of the present utility model
Fig. 4 is electric bridge plate process Installation figure of the present utility model
Fig. 5 is an electric hookup of the present utility model.
Accompanying drawing has been represented structure of the present utility model and embodiment, describes the relevant details of embodiment below more in conjunction with the accompanying drawings.Whole sclerometer comprises pressing (1), presses foot (2).Spring (3) is contained in presses in the foot (2), and pressing (1) links to each other with the pressure foot and passes the center of pressing foot (2), and an end of pressing contacts with sensor (4) (being adjustable potentiometer), and sensor (4) becomes to be electrically connected with the LCD panel of indication.Its electric part is that stabilized voltage supply, bridge diagram and Ic7601 assembly constitute display circuit board, and Fig. 2,3,4,5 is seen in the installation of embodiment.Its each electric elements all are standard component, will not give unnecessary details.The principle of work of complete machine is to connect with the mains, and stabilized voltage supply is that Ic7601 supplies 9 volts of voltage stabilizing electricity, and numeral appears in display board, supplies with measuring bridges for 6 volts, transfers 1W
1, 1W
3, 3W
1Occur zero, work as 1W
2When being driven 2.5mm by connecting rod, full scale is 100.0, in case mix up, as long as mechanical linkage is stable, and in 1W
2Be connected firmly the instrument use of just can switching at any time.
Signal results from the balance of measuring bridge, when being mechanical shift, make the electric bridge out of trim produce voltage, the size and the displacement of this voltage are in direct ratio, and linearization is from 0～2.5 displacement, electric bridge is changed out the signal of 0～100mv, sends into the Ic7601 signal and goes into end, produces dual integration A/D conversion, warp is from zero-bit, signal integration, reverse integral produces pulsed quantity and promptly enters the counting demonstration.
Claims (3)
1, a kind of rubber digital display sclerometer includes pressing (1), presses foot (2), spring (3) and indicating device (5), it is characterized in that an end of pressing (1) is that electric wiring is connected with sensor (4) contact, sensor (4) with the connected mode of indicating device.
2, rubber digital display sclerometer as claimed in claim 1 is characterized in that indicating device (5) shows for liquid crystal digital.
