Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

Referring to fig. 1, the present invention provides a high-precision level, which comprises two containers 1, wherein a liquid and a buoy 3 suspended on the liquid are arranged in the container 1. The container 1 is an aluminum product. The buoy 3 is a hollow plastic block or a hollow aluminum block, so that the influence of water absorption on floating is avoided.

The two vessels 1 are communicated through a connecting pipe 2 so that the liquid level inside is leveled. The connection pipe 2 is a hose, and the connection pipe 2 is connected to the bottom of the container 1.

A sensor 4 for measuring the height position change of the buoy 3 is arranged in the container 1. Fig. 1 is a schematic representation of the sensor 4, and does not specifically show the structure, connection manner, connection structure, and location thereof. The sensor 4 may be a grating displacement sensor, a magnetic grating displacement sensor, a gravity sensor or other form of, but not exhaustive, sensor 4 for measuring distance. The sensor 4 can directly measure the distance, and the selection requirement is that the precision at least reaches 0.01 mm; when the distance cannot be directly measured and conversion is required, the accuracy of the converted distance is 0.01 mm. In addition, the structural form of the sensor 4 includes:

1. when the sensor 4 needs to be implemented by a transmitting end and a receiving end, the transmitting end and the receiving end are respectively arranged on the buoy 3 and the top of the container 1;

2. referring to fig. 2, when the sensor 4 is a magnetic grid displacement sensor or a grating sensor, the magnetic grid plate 5 is disposed on the top of the buoy 3 and the magnetic grid measuring head 6 is disposed on the inner wall of the container 1, or the grating plate is disposed on the top of the buoy 3 and the grating measuring head is disposed on the inner wall of the container 1;

3. referring to fig. 3, when the gravity sensor 7 is selected, the gravity sensor 7 is disposed on the top of the container 1, the gravity sensor 7 is connected to the float 3 through a flexible rope, when the liquid level in the container 1 occurs, the force applied to the gravity sensor 7 by the float 3 will change, and the moving distance of the float 3 can be known through conversion.

The sensor 4 is electrically connected to a processor for displaying the value measured by the sensor 4. The sensor 4 directly displays the value measured by the sensor 4, and the reading is very convenient.

In specific implementation, the two containers 1 are placed on a reference plane (the reference plane is a workbench top with standard flatness), then the numerical values are cleared to correct the reference, then the two containers 1 are respectively placed at two ends of a plane to be measured, and then the numerical values displayed by a processor are read. The liquid levels in the two containers 1 are always flush, the height from the top of the buoy 3 to the liquid level is also fixed, but when the two ends of the plane to be measured are uneven, the distance between the sensor 4 at the top of the container 1 and the buoy 3 is changed, so that the levelness of the plane to be measured can be known according to the change of the number. For example, if the plane to be measured is left low and right high, the processor will display the values of the two sensors 4 as 0.03mm and-0.03 mm, respectively, so that the difference in height between the left and right ends of the plane to be measured is known to be 0.03 mm.

It is to be noted that when the gravity sensor 7 is used, the measured values are based on the values detected by the sensor 4 in the container 1, in which the liquid level is falling.

In conclusion, the whole operation process does not need complicated operations, such as tool adjustment, driving of a machine tool during meter printing and the like; the numerical value can be read quickly and directly, and the method is very convenient; the high-precision measurement is realized by relying on the high-precision sensor 4, the two liquid levels are always parallel and level, so that the position change of the buoy 3 is very accurate, and compared with other structural tools, the error causes are fewer.

In addition, the device can be used for measuring whether the height difference of the two planes reaches the standard or not.
