Abstract
The utility model discloses a fuel sensor liquid level standardization detector which comprises a base and is characterized in that a guide pillar is arranged on the base, a lead screw which is parallel to the guide pillar is arranged on one side of the guide pillar in an erected mode, a guide seat is arranged on the lead screw in a matched mode, a clamping claw is arranged on the outer side of the guide seat, a guiding hole which is matched with the guide pillar is further formed in the position, between the lead screw and the clamping claw, of the guide seat, a cylinder body is arranged at the position, below the clamping claw, of the base, and the lead screw is driven by a motor. The fuel sensor liquid level standardization detector is reasonable in structural design. According to the fact that the lead screw is driven to detect through the motor, location can be accurately achieved, and due to use of a transparent plastic bucket, a glass water tank or the cylinder body enabling a liquid level inside the cylinder to be seen clearly, an error value of a detection result is reduced greatly and an accurate property of a fuel sensor is improved.
Description
Technical field
The utility model relates to the fuel sensor liquid level and demarcates field, relates in particular to a kind of fuel sensor liquid level and demarcates pick-up unit.
Background technology
after processing, fuel sensor needs to carry out the liquid level demarcation, it is mostly to move and detected resistance by the position to fuel sensor that its liquid level is demarcated, then curve plotting figure obtains, detect in the prior art is mainly the standard manually the fuel sensor float moved around as detecting, it must be deep in the middle of fuel tank, fuel sensor float floating position in fuel tank is not easy to determine on the one hand, 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, thereby cause the testing result error amount very large, can not meet request for utilization
.
The utility model content
The purpose of this utility model is in order to make up the deficiency of prior art, provide a kind of fuel sensor liquid level to demarcate pick-up unit, utilizing the driven by motor screw mandrel to detect can locate accurately, and transparent plastic pail, glass water tank maybe can be seen the use of the cylindrical shell of liquid level in cylindrical shell clearly, the testing result error amount made reduces greatly, has improved the accurate performance of fuel sensor.
The utility model is achieved through the following technical solutions:
A kind of fuel sensor liquid level is demarcated pick-up unit, include base, it is characterized in that: described base is provided with guide pillar, one bogie side frame of described guide pillar is provided with screw mandrel in parallel, coordinate on described screw mandrel guide bracket is installed, the described guide bracket outside is provided with claw, on the guide bracket between described screw mandrel and claw, also is provided with the pilot hole coordinated with guide pillar, the base of described claw below 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 in respectively on the upper and lower screw mandrel mount pad of guide pillar one side, 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 the claw web joint, and described claw web joint is provided with the U-shaped claw.
Described cylindrical shell is the cylindrical shell that transparent plastic pail, glass water tank maybe can be seen liquid level in cylindrical shell clearly.
Be distributed with scale mark on described cylindrical shell.
Its principle is: with the driven by motor screw mandrel, move up and down, fuel sensor is contained on claw, motion together, the phase good stability, be not easy deflection, keep balance, facilitate the stably measured of resistance value, and described cylindrical shell is the cylindrical shell that transparent plastic pail, glass water tank maybe can be seen liquid level in cylindrical shell clearly, but diameter is observed the position of fuel sensor float in cylindrical shell, convenient movement and the control of controlling screw mandrel simultaneously, the testing result error amount made reduces greatly, has improved the accurate performance of fuel sensor.
The utility model has the advantages that:
The utility model reasonable in design, utilizing the 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, has improved the accurate performance of fuel sensor.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
