Description
The utility model relates to detecting instrument, and it relates to the electromechanical transformation apparatus of spring digital display scale specifically.
(patent No.: the spring sensor of invention has been realized the conversion of spring deformation to electronic signal to the inventor ZL00251500.8) at utility model patent " a kind of spring sensor ", the digitizing of spring scale scale is shown become possibility, the physical construction of spring balance also will greatly be simplified simultaneously, to reduce production cost, improve the reliability and the serviceable life of scale.
The purpose of this utility model just provides the electromechanical transformation apparatus of spring digital display scale, realizes that the digitizing of spring balance shows.
The electromechanical transformation apparatus of the utility model spring digital display scale is by spring sensor (19), scale base is formed, scale base is by the plane EFGH (1) that weighs, baseplane (2), frontal plane FBCG (3), the parallelogram hollow cylinder that back plane EADH (4) surrounds constitutes, the baseplane of scale base (2) is placed horizontally on the worktable, except that baseplane (2) maintain static as the reference plane, its excess-three plane is all movable, weigh plane EFGH (1) as the scale pan, place weighed object, angle between adjacent two planes can change freely, the weighing spring of spring balance is exactly the spring L of spring sensor (19), spring L one end is fixed on the immobile point of scale base by insulated column (15), the other end is by lead (20), dead ring (16) is fixed on the free cheek, and the output terminal of spring sensor (19) is connected with data processor after the conversion of A-D converter.
The electromechanical transformation apparatus of the utility model spring digital display scale has solved the conversion of spring digital display weigher tool to electronic signal, and simple and reliable cost is low, has reduced the height of scale, makes the spring balance profile more practical.
The utility model has following accompanying drawing:
Fig. 1 is the electromechanical transformation apparatus schematic diagram of spring digital display scale.
Fig. 2 is spring Fundamentals of Sensors figure.
Existing accompanying drawings the utility model embodiment.Spring sensor (19) is by square wave oscillation generator IC1, resistance R 1, crystal JZ, capacitor C 1, C2, triode G1 forms, the inertia circuit is by resistance R 2, spring L is composed in series the inertia circuit of differential form, pulse conversion circuit is by triode G2, simulation beginning IC2, resistance R 3, R4, capacitor C 3 is formed, the output in square-wave pulse signal source is connected with the end of R2 in the inertia circuit by the emitter e of the G1 on 7 pin of IC1, the output terminal resistance R 2 of inertia circuit is connected with the base stage b of the common contact of spring L with the input end G2 of pulse conversion circuit, the other end ground connection of L in the inertia circuit, 7 pin of IC1 in 13 pin of the control input end IC2 of IC2 and the square-wave pulse signal source are connected, the output terminal R4 of pulse conversion circuit, the common contact of C3 is an output terminal, is connected by the input end of lead (22) with the one-chip computer PIC16C73 (21) of band A-D converter.
Baseplane (2) is plane ABCD, plane ABCD, plane (1), (3), (4) adjacent two planes connect with hinge (7), (8), (9), (10), (11), (12), (13), (14), the angle of plane ABCD and back plane (4) is greater than 90 °, the end of spring L is fixed on the ABCD of plane by insulated column (15), and the other end is fixed on the back plane (4) by lead (20), dead ring (16).Display is in the school zero condition when weighing thing not putting, when weighed object is positioned over the plane of weighing (scale pan) (1), it is big that angle between plane ABCD and the back plane (4) becomes, spring L elongation, the DC voltage of spring sensor (19) output diminishes, the variation of this voltage shows the weight result through nixie display (26) after band A-D converter single chip computing machine PIC16C73 (21) calculation process.As mix unit price input keyboard (25) and interlock circuit, then can show the amount of money.Spring digital display scale with the utility model manufacturing can be widely used in making basic measurement instrument in the trade in urban and rural peasant market, is the regeneration product of spring scale scale.
