Parallel rotating angle measuring mechanism

Abstract

This invention refers to a parallel rotation angle measuring mechanism, which contains rigid body, first straight line displacement sensor, movement pair, revolving pair, second straight line displacement sensor, third straight line displacement sensor and machine frame, wherein two ends of three straight line displacement sensors respectively connected with machine frame by revolving pair, the active rule and static rule connected by straight line displacement pair. Said invention solves the problem of rigid body rotation angle when one rigid body of measured plane rotates around any axle in vertical plane.

Description

technical field [0001] The invention relates to measurement technology engineering, in particular to a novel parallel rotation angle measurement mechanism. Background technique [0002] At present, the sensors that measure angles in real time include rotary encoders and angle encoders, etc., and their rotation centers are required to be concentric with the measurement axis during installation, which limits the scope of use. When a rigid body on the plane rotates around any point of itself, the angle of rotation cannot be directly measured by the angle sensor; the encoder is used as the mechanism for measuring components. When the accuracy of the measurement angle is high, the encoder is selected. The cost is high, and when there is a high displacement accuracy requirement, the algorithm that uses the encoder to measure the angle and multiply the arc length cannot meet the displacement accuracy requirements. Utilize the high-precision linear displacement sensor to measure th...

[0002] At present, the sensors that measure angles in real time include rotary encoders and angle encoders, etc., and their rotation centers are required to be concentric with the measurement axis during installation, which limits the scope of use

When a rigid body on the plane rotates around any point of itself, the angle of rotation cannot be directly measured by the angle sensor; the encoder is used as the mechanism for measuring components. When the accuracy of the measurement angle is high, the encoder is selected. The cost is high, and when there is a high displacement accuracy requirement, the algorithm that uses the encoder to measure the angle and then multiply the arc length cannot meet the displacement accuracy requirements

Using a high-precision linear displacement sensor to measure linear displacement and then calculate the mechanism for measuring angle has not been reported yet.
