Description

A kind of liquid level of fuel sensor demarcates pick-up unit and method
Technical field
The present invention relates to liquid level of fuel sensor and demarcate field, particularly relate to a kind of liquid level of fuel sensor and demarcate pick-up unit and method.
Background technology
Need to carry out liquid level demarcation after fuel sensor processes, it is mostly carry out detection resistance by moving the position of fuel sensor that its liquid level is demarcated, then curve plotting figure obtains, detect the standard mainly moved around by fuel sensor float manually as detecting in the prior art, it must be deep in the middle of fuel tank, the position that fuel sensor float is floating in fuel tank is on the one hand not easy to determine, on the other hand when manual mobile fuel sensor, poor stability in its moving process, easy deflection or imbalance, affect the measurement of fuel sensor resistance value, thus cause testing result error amount very large, and its detection method trouble, efficiency is low, request for utilization can not be met .
Summary of the invention
The object of the invention is the deficiency in order to make up prior art, provide a kind of liquid level of fuel sensor and demarcate pick-up unit and method, utilize driven by motor screw mandrel to detect can locate accurately, and transparent plastic pail, glass water tank maybe can see the use of the cylindrical shell of liquid level in cylindrical shell clearly, the testing result error amount made reduces greatly, not only increase the accurate performance of fuel sensor, simultaneously easy to detect, work efficiency is high.
The present invention is achieved through the following technical solutions:
A kind of liquid level of fuel sensor demarcates pick-up unit and method, include base, it is characterized in that: described base is provided with guide pillar, the side erection of described guide pillar has screw mandrel in parallel, described screw mandrel coordinates and is provided with guide bracket, be provided with claw outside described guide bracket, described screw mandrel is also provided with on the guide bracket between claw the pilot hole coordinated with guide pillar, base below described claw is provided with cylindrical shell, and described screw mandrel is driven by motor.
The upper and lower side of described screw mandrel is rotatably installed on the upper and lower screw mandrel mount pad of guide pillar side respectively, and described upper and lower screw mandrel mount pad is fixedly mounted on guide pillar respectively.
The outside of described guide bracket is connected with claw web joint, and described claw web joint is provided with U-shaped claw.
Described cylindrical shell is the cylindrical shell that transparent plastic pail, glass water tank maybe can see liquid level in cylindrical shell clearly.
Described cylindrical shell is distributed with scale mark.
Described claw is installed with fuel sensor to be detected, and the float of fuel sensor to be detected is positioned at cylindrical shell, concrete steps are as follows: first in cylindrical shell, load onto quantitative oil or water, make the float of clamping fuel sensor to be detected at oil or water float, then rotated by driven by motor screw mandrel, thus indirectly drive moving up and down of fuel sensor to be detected, the data line of described fuel sensor to be detected is connected with single-chip data processor, the voltage that real-time calculating and curtage and the motor of display fuel sensor to be detected export or electric current, the voltage exported by curtage and the motor of same time list fuel sensor to be detected or electric current, simulate the curve coefficients between voltage or electric current that the curtage of fuel sensor to be detected and motor export, curve coefficients remote mode or short range mode are input among the calculation procedure in single-chip data processor, namely the oil mass completing fuel sensor to be detected is demarcated.
Its principle is: move up and down with driven by motor screw mandrel, fuel sensor is contained on claw, move together, its good stability, be not easy deflection, keep balance, facilitate electric current, the stably measured of voltage, and described cylindrical shell is transparent plastic pail, glass water tank maybe can see the cylindrical shell of liquid level in cylindrical shell clearly, directly can observe the position of fuel sensor float in cylindrical shell, convenient movement and the control controlling screw mandrel simultaneously, the testing result error amount made reduces greatly, improve the accurate performance of fuel sensor, do not need to carry out in mailbox when it detects simultaneously, easy to detect, work efficiency is high.
Advantage of the present invention is:
Reasonable in design of the present invention, utilize driven by motor screw mandrel to detect can locate accurately, and transparent plastic pail, glass water tank maybe can see the use of the cylindrical shell of liquid level in cylindrical shell clearly, the testing result error amount made reduces greatly, improve the accurate performance of fuel sensor, easy to detect, work efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
