Abstract
The invention discloses a displacement signalling device, including the potentiometer and the thread pole, between which there are the axis and the gear, by whith the vertical motion of the thread pole is transformed into the rotation of the potentiometer. The signalling device can also be set with two travel switches matching two cams on the third axis. The output signal is analogue one, which is converted into digital signal. The travel precision can reach 1 mm.
Description
Technical field
The invention belongs to the measurement technical field of measurement and test, be specifically related to a kind of displacement signal device, be particularly useful for the measurement of lock position.
Background technology
On the home market multiple displacement signal measurement device is arranged now, count example with liquid level, multiple shaped article is arranged on the market, but be numeric type, its price is expensive.As commercially available ZGC-2 type full dose photoelectric coding gate level meter, its range is that 0～10m or 0～20m, precision are 0.5cm or 1cm, and error ± 0.2%, speed are 0～30cm/s.And measurement resolution can only reach 0.5cm, is difficult to satisfy various engine requests.
Summary of the invention
The object of the present invention is to provide a kind of displacement signal device that can overcome above-mentioned defective, its measuring accuracy is higher, and range of application is wider, and cost is lower.
For achieving the above object, a kind of displacement signal device comprises potentiometer and the screw mandrel that links to each other with measured object, is provided with axle and gear therebetween, the vertical movement of screw mandrel is converted into the rotation of described potentiometer by axle and gear.
Displacement signal device provided by the invention, its output signal is a simulating signal, after analog module converted digital signal to, the stroke accuracy of lock position can reach 1mm, and simple in structure, manufacturing cost is lower, can satisfy the requirement of intelligence system.
Description of drawings
Fig. 1 shows for the structure of a kind of embodiment of displacement signal device of the present invention
Intention (front view);
Fig. 2 is the vertical view of displacement signal device shown in Fig. 1.
Embodiment
Structure of the present invention as shown in Figure 1 and Figure 2, comprise first gear 13 and second gear 14 that are positioned on first 9, first gear 13 is meshed with the screw mandrel 8 that links to each other with measured object, second gear 14 is meshed with the 3rd gear 15 that is positioned at second 4, also be provided with the 4th gear 16 on second 7, the 4th gear 16 is meshed with the 5th gear 17 that is positioned on the 3rd 7, at the 3rd the other end potentiometer 2 is housed.In order to limit the stroke of its standard-sized sheet, complete shut-down, this displacement signal device also comprises two cams 6,6 ' that are positioned on the 3rd 7, and the travel switch 5,5 ' that is complementary with it.Two ends at above-mentioned parts are equipped with support plate 3,10, its outer outer cover 1 that is with.
The present invention is sent to the lifting moving of screw mandrel 8 on the potentiometer 2 with set of gears 13-17 (being designated as z1, z2, z3, z4, z5), the rotation that becomes potentiometer will be moved, make the proportional variation of physical location of the resistance and the screw mandrel of potentiometer, import in the computing machine from the electric signal that potentiometer is obtained.
Determining of speed ratio: establish screw mandrel pitch T, total travel L, according to screw mandrel, pitch is determined several and the number of teeth of touching of Z1.
Then Z1 saves garden perimeter L 1=3.14*m1*Z1
The Z1 rotating speed, n1=L/L1
If 320 ° of potentiometer rotation angle, n2=320/360
Gear ratio I=n1/n2=Z3*Z5/ (Z2*Z4)
As can be seen, above-mentioned concrete structure is not the unique implementation of the present invention from the explanation of above-mentioned principle and structure, can be according to the size of measured object stroke section, the number of axle and gear between screw mandrel and the potentiometer is set.Its stroke section is big, and a plurality of axles and gear just need be set, and vice versa.
This displacement signal device can cooperate reservoir strobe computer remote automatic control system to be used for the reaction gate screw mandrel displacement instrument of switch.
Displacement signal device of the present invention, its basic functional principle to the electric signal of converting with the collection of an angular displacement precision resistor again for through gearing mesh the vertical motion of lock position being converted to circular motion, delivers to PLC and handles.Simultaneously, standard-sized sheet, the travel limits of complete shut-down also is aided with two micro limit switch with two cams and is achieved.The entire equipment volume is small and exquisite attractive in appearance, and is easy for installation, the measuring accuracy height.Through field test, its working stability is reliable, and transmission precision surpasses other similar products.
