Plane parallelism measurement device

Abstract

The invention discloses a plane parallelism measurement device. The plane parallelism measurement device comprises a square or cylindrical shell (1), an A / D (analogue-to-digital) converter (8), a microcontroller (9), a power supply (10), a display screen (11) and a measurement module, wherein the measurement module comprises three grooves and three distance sensors, wherein one distance sensor is fixedly arranged in one groove correspondingly; the three grooves are all positioned on the same plane of the shell (1), and the central points of the three grooves are not arranged on the same line; the three distance sensors are respectively connected with the A / D converter (8); the A / D converter (8) is connected with the microcontroller (9), the power supply (10) and the display screen (11) in sequence; distance is measured by the three distance sensors at the same time and then is processed, and a measurement result is output through the display screen (11). By the plane parallelism measurement device, the distance between two planes are measured, the parallelism is judged directly and accurately, and the parallelism measurement of planes can be provided very well by utilizing automatic measurement.

Description

Technical field [0001] The present invention involves a measurement device, which specializes in a device for plane parallel measurement, which belongs to the technical field of measurement equipment. Background technique [0002] During the measurement process, it is often tested in a given plane such as vertical plane or horizontal plane. The commonly used measuringrs have a precision meter instrument with a frame level instrument, the elephant level, electronic level, and the self -standard direct instrument.These devices are measured for a plane, and when the measurement between the two planes is needed, there are problems, and the two plane position relationship cannot be obtained directly by measurement.Especially when the measured surface of the test has a straight line error. When the measuring device is placed on different measured parts, its tilt corner will change, making the measurement difficult, and the measurement can also be measured by measuring the horizontal c...

Problems solved by technology

[0002]In the process of measurement, detection is often carried out on a given plane such as a vertical plane or a horizontal plane. The commonly used measuring instruments include frame level, composite level, and electronic level Precision measuring instruments such as autocollimators and autocollimators for measuring small angle changes, these devices are all for the measurement of a plane, but when it is necessary to measure between two planes, there is a problem, and the measurement of the two planes cannot be obtained directly Positional relationship

In particular, there is a straightness error on the surface to be measured. When the measuring instrument is placed on different parts to be measured, its inclination angle will change, making the measurement difficult, and the measurement can be judged by measuring the level of the two planes respectively. The parallelism increases the measurement steps and prolongs the measurement process, which easily leads to the existence of errors in the measurement process. Therefore, there are certain limitations in the existing measurement of the positional relationship between the two planes, and for the two planes The device for direct measurement of the parallelism has not been widely involved
