Abstract

The invention discloses a calibration device for an inclination angle sensor, which is characterized in that a dividing head is arranged on an adjustable horizontal base; a three-jaw chuck fixedly connected with the lateral part of the dividing head is used for clamping a sensor fixed frame; an angular displacement platform capable of adjusting a horizontal inclination angle is mounted on the sensor fixed frame; a to-be-calibrated sensor is mounted on the angular displacement platform through a sensor clamp; the dividing head adopts a rotatable component with a horizontal rotating shaft; the end of the horizontal rotating shaft of the dividing shaft is fixedly connected with a rotating handle; the dividing head is used for measuring a rotating angle of the sensor fixed frame by means of an angle vernier coded disc and a dividing head angle coded disc arranged on the horizontal rotating shaft of the dividing head; and the rotating shaft of the sensor fixed frame and the rotating shaft of the dividing head are arranged at 90 degrees in a horizontal plane. The invention has the advantages of simple structure, high calibration accuracy and convenient use.

Description

technical field [0001] The invention relates to an angle sensor calibration device, in particular to an inclination sensor calibration system. Background technique [0002] For a long time, people have relied on bubble-type spirit levels to measure levelness, and judge the level by checking whether the bubble is level in the observation window. Since the bubble level can only qualitatively judge whether it is level, it cannot quantitatively measure the degree of level / inclination, and cannot directly read, the measurement results are greatly affected by human factors, which brings a lot of inconvenience and errors in practical applications. With the development of electronic technology, people have developed a variety of inclinometers for levelness and inclination measurement, such as digital inclinometers, pulse inclinometers and photoelectric inclinometers. However, these inclinometers are affected by problems such as the consistency of the output of their inclination sen...
