The invention discloses a spherical moving device. The spherical moving device comprises an arc guide rail, an arc guide rail moving device, an upper hanging piece, an annular guide rail and an annular guide rail moving device, wherein the arc guide rail moving device can move along the arc guide rail, the upper hanging piece is connected with the upper end of the arc guide rail in a hinging way, the annular guide rail moving device can move along the annular guide rail, the bottom end of the arc guide rail is fixedly connected with the annular guide rail moving device, the circle center of the arc guide rail is in the axis of the annular guide rail, and the arc guide rail moving device is provided with a positioned element. The spherical moving device disclosed by the invention has the advantages that the positioned element is enabled to move on a spherical surface, the positioned element can reach any position on the spherical surface, the reachable space is sufficient, the axis of the positioned element always points to the spherical center of a motion spherical surface, longitude and latitude locating information of the positioned element can be directly associated to the motion quantity of a motion joint, the resolving quantity is small, the structural stiffness is large, the reliability is also realized when the positioned element moves on a large-radius spherical surface, and the system stability is ensured due to the design on the motion joint.
Description
technical field [0001] The invention relates to a mobile device, in particular to a mobile device on a large radius spherical surface. Background technique [0002] At present, the mobile devices developed at home and abroad can be divided into three types: 1. Cartesian coordinate type; 2. Spherical coordinate type; 3. Cylindrical coordinate type. It is rare for mobile devices moving on hollow spherical surfaces. The Cartesian coordinate mobile device calculates the movement amount of each linear motion drive mechanism through the latitude and longitude positions on the spherical surface, and then adjusts the posture of the end to meet the position of the positioned component pointing to the virtual center point; the spherical coordinate mobile device uses a spherical joint. It is rare in practical application, but two rotating hinges are used to replace the spherical hinge, its structure is complex, and it is also necessary to calculate the motion parameters from the latit...
