智能球鉸鏈空間回轉(zhuǎn)角度測量及精度提升技術(shù)
[Abstract]:The spherical hinge has three degrees of freedom of rotation, can realize free rotation in any direction, and has the characteristics of compact structure, high stiffness, flexible motion, strong bearing capacity, large workspace and so on. It is widely used in robot and parallel mechanism. Parallel machine tool and parallel measuring machine, etc. The detection of spherical hinge space rotation angle is of great significance to the prediction, feedback and attitude control of the motion error of the mechanism. At present, there is still a lack of methods to detect the spherical hinge space rotation angle with high precision. In this paper, a kind of embedded intelligent ball hinge based on magnetic effect is developed, which embeds the permanent magnet into the ball head without affecting the key indexes such as the bearing capacity of the ball hinge, the precision of rotation and the flexibility of movement, and so on, in this paper, a kind of embedded intelligent ball hinge based on magnetic effect is developed. A number of Hall sensors are embedded in the ball nest and the permanent magnet rotates with the ball rod. The sensor detects the magnetic field of its position changes. According to the theory of magnetic field modeling and inverse solution the spherical hinge space rotation angle can be identified and measured. The main work of this thesis is as follows: based on the equivalent magnetic charge model, the expressions of the external magnetic field distribution with single and multiple permanent magnets as magnetic field sources are established respectively; The shape of permanent magnet and the placement mode of Hall sensor are determined. The optimal matching position between the sensor and permanent magnet is obtained by Matlab simulation, and the first embedded spherical hinge prototype of the project team is designed and manufactured. The measuring accuracy and resolution of the prototype are analyzed by the experimental comparison device. The experimental data show that when the angle of spherical hinge is small, the measurement accuracy of 偽 and 尾 angle is higher, and the measurement error increases with the increase of measuring range. In the range of 鹵10 擄rotation, the maximum error of 偽 is 32.34, and the minimum error is 0.12. The average error is 11.58, the maximum error of 尾 is 26.16, the minimum error is -0.24 and the average error is 12.060.The average error of 偽 and 尾 is 18.84 'and 20.34' respectively within 鹵20 擄. Compared with the previous research results, the measuring range, measuring precision and resolution of this method are improved, and it basically has the conditions of application in the field of medium and low precision.
